email[edit]

This server hosts mail for johncompanies.com (mail.johncompanies.com). Sendmail 8.13.6/8.13.6 is listening on 69.55.230.2 port 25 for incoming mail. Relaying is allowed per /etc/mail/relay-domains Other addresses (aliases) are defined per /etc/mail/aliases

The following active users have mail hosted on this server:

dave
linux
support
payments
sales
tech1
info

Traditionally, mail is checked via shell apps (pine). qpopper (pop3s) is running to allow mail downloading. Checking mail in this way causes an opened INBOX in pine to lock read-only. For this reason, we tee incoming mail to support and linux to tech1.

Procmail rules are setup to filter spam and send text messages. They are enabled for info, support, linux, tech1, dave and can be found in ~/Procmail/, for example:

# more ~support/Procmail/rc.emergency
:0c # use c only if you want to forward a copy and file the original later
* ^Subject:.*\<emergency\>
* ! ^Subject:\<re\>
  {
   :0h
   FROMANDSUBJECT=|formail -XFrom: -XSubject:

   :0fwh
   | /usr/local/bin/formail -I"Subject: " -I"To: pager@johncompanies.com" ; echo $FROMANDSUBJECT ; echo

   :0
  ! -t
  }

control: cd /etc/mail; make stop (stop), cd /etc/mail; make start (start)

The following aliases are also in place:

debian:         linux
jobs:   info
careers:        info
#reboot:         6128102202@txt.att.net
#reboot:         8582298897@vtext.com
reboot:         pager
#pager: 8582298897@vtext.com
pager:  4158718324@txt.att.net
tech1on:  "| /usr/local/sbin/tech1on.sh"
tech1off:  "| /usr/local/sbin/tech1off.sh"

To change them, edit /etc/aliases and then run newaliases

Note on tech1: this address was setup as a read-only address to be mirrored on all email coming into support and linux. We set this up so we could easily check support mail via a pop client- popping email locks out the user in pine so checking support/linux directly via pop was not an option. When checking and responding to email that comes into tech1, care should be taken to make sure it is sent as/under an address other than tech1. This is cause tech1 is not monitored by support staff as closely as email to support/linux. Further, the tech on call may not be checking tech1. Lastly, because of the nature of the copying, you will sometimes notice certain automated email/notices are received 2x in support- this is because of/related to the tech1 mirror.

To enable it (on mail, run):

~support/tech1on.sh

To disable

~support/tech1off.sh

Or via email:

tech1on@johncompanies.com tech1off@johncompanies.com

bigbrother[edit]

There is a client running on mail (which monitors the services running on mail and mail itself), installed under /usr/home/bb/bbc1.9e-btf
And the big brother pager/server (which displays information gathered from all bb-monitored machines, including mail) is installed under /usr/home/bb/bbsrc/bb1.9i-btf

Both are running under the user bb

Refer to BigBrother for more about use.

DNS (ns1c.johncompanies.com)[edit]

ns1c is a jail running on the mail server, who's IP is 69.55.225.225

It's running from /mnt/data1/ns1c-dir

See DNS for more details

nat[edit]

Summary[edit]

This is the main machine to which we ssh and runs all our screen sessions. Further, it's ip runs in a special block which is not routed through the firewall and this is somewhat immune to DoS attacks which hobble our firewall. Lastly, it acts as a nat server for certain/random devices on the private network.

Location: castle, cab 3-7
OS: FreeBSD 9.1 i386
Networking: Priv IP: 10.1.4.1, Pub IPs: 69.55.233.195, 69.55.233.196, 69.55.233.197, 69.55.233.198, 69.55.233.199. 1 onboard and 1 PCI

A simple entry looks like:

bimap fxp0 10.1.4.240/32 -> 69.55.233.197/32

Which essentially means make private IP 10.1.4.240 reachable on 69.55.233.197 and allow 10.1.4.240 to communicate with the public internet via 69.55.233.197

To reload new rule config:

ipnat -C -F -f /etc/ipnat.rules

You may want to setup natting, as above, when you need to reach a DRAC card's web interface, wherin the DRAC card only has a private IP.

bwdb[edit]

Summary[edit]

This machine tracks and stores network traffic (netflow) at castle. It is our means to monitor customer bandwidth usage.

Location: castle, cab 3-7
OS: FreeBSD 4.10 x86
Networking: Priv IP: 10.1.4.203 There are 2 onboard nic's, one of which is the "listener"
Hardware: Custom 1U. Single power supply.
Drives: one 250 GB (2 x 250GB) RAID1 array running on a Promise IDE RAID card.

Services Provided[edit]

netflow
mysql
bigbrother
snmp

netflow[edit]

The main function of this server is to run netflow on an eth device in promiscuous mode so as to hear everything happening on the port (wherein all network traffic is mirrored to that port via the cisco swith). Every 15min, it creates a flow file under /usr/home/flows/ (organized by date). The flow file contains all traffic data for a 15min increment of time.

A cronjob moves that flow file (or files if there are multiple due to some delay)

1,16,31,46 * * * * /usr/home/flowbin/queue.pl

into a processing queue: /usr/home/working

Then a separate file processes whatever flow files it finds there, inserting the data into the local mysql database:

2,17,32,47 * * * * /usr/home/flowbin/processflows.pl

mysql[edit]

The database storing all the traffic data is named traffic Tables:

+---------------------------+

So as you see we store each class-C block in its own table, for efficiency. Further, we store and organize data in 4 ways: "daily" tables and 15-minute granularity tables, and for each of those we track simple IP traffic and port-specific traffic. The daily tables contains 2 entries (one for each direction) for each IP for each day. For the current day, the row data is incremented as the day goes on.

mysql> describe dailyIpTotals_69_55_224;
+-----------+-------------+------+-----+---------+-------+
| Field     | Type        | Null | Key | Default | Extra |
+-----------+-------------+------+-----+---------+-------+
| id        | varchar(23) |      | PRI |         |       |
| date      | date        | YES  |     | NULL    |       |

| packets   | int(11)     | YES  |     | NULL    |       |
+-----------+-------------+------+-----+---------+-------+

mysql> select * from dailyIpTotals_69_55_224 limit 1\G
*************************** 1. row ***************************
       id: 6955224194-20100917-1
     date: 2010-09-17
       ip: 69.55.224.194
direction: 1
   octets: 8821
  packets: 91

The id is a unique identifier (key), direction indicates incoming or outgoing traffic (outbound = 2, inbound = 1), octets are the amount of traffic in kilobytes, and packets is the total number of packets.

The 15-minute table has similar information, but it's organized in 15 minute increments:

mysql> describe ipTotals_69_55_224;
+-----------+------------+------+-----+---------+-------+
| Field     | Type       | Null | Key | Default | Extra |
+-----------+------------+------+-----+---------+-------+
| date      | datetime   | YES  |     | NULL    |       |
| ip        | char(15)   | YES  | MUL | NULL    |       |
| direction | tinyint(1) | YES  |     | NULL    |       |
| octets    | bigint(20) | YES  |     | NULL    |       |
| packets   | int(11)    | YES  |     | NULL    |       |
+-----------+------------+------+-----+---------+-------+

mysql> select * from ipTotals_69_55_224 limit 2\G
*************************** 1. row ***************************
     date: 2010-01-11 19:30:00
       ip: 69.55.224.13
direction: 1
   octets: 288
  packets: 6
*************************** 2. row ***************************
     date: 2010-01-11 19:30:00
       ip: 69.55.224.12
direction: 1
   octets: 216
  packets: 4

So for a given IP, there will be 192 rows in a given day: 4 rows per hour, *2 for 2 directions, *24 for 24hours in a day. Obviously this table is large which is why we broke it down into a daily table for quick, easy, daily-summary access.

That covers the simple traffic tabulation tables. We also track traffic by port:

mysql> describe dailyPortTotals_69_55_224;
+-----------+-------------+------+-----+---------+-------+
| Field     | Type        | Null | Key | Default | Extra |
+-----------+-------------+------+-----+---------+-------+
| id        | varchar(28) |      | PRI |         |       |
| date      | date        | YES  |     | NULL    |       |
| ip        | varchar(15) | YES  | MUL | NULL    |       |
| direction | tinyint(1)  | YES  |     | NULL    |       |
| protocol  | smallint(3) | YES  |     | NULL    |       |
| port      | int(11)     | YES  |     | NULL    |       |
| octets    | bigint(11)  | YES  |     | NULL    |       |
| packets   | int(11)     | YES  |     | NULL    |       |
+-----------+-------------+------+-----+---------+-------+
8 rows in set (0.00 sec)

mysql> select * from dailyPortTotals_69_55_224 limit 1\G
*************************** 1. row ***************************
       id: 695522496-20091218-1-6-23
     date: 2009-12-18
       ip: 69.55.224.96
direction: 1
 protocol: 6
     port: 23
   octets: 1796
  packets: 30

mysql> select * from portTotals_69_55_224 limit 1\G
*************************** 1. row ***************************
     date: 2010-09-07 18:45:00
       ip: 69.55.224.254
direction: 1
 protocol: 6
     port: 99999
   octets: 144
  packets: 3

This is largely the same with 2 more additions: protocol (1=ICMP, 6=TCP, 17=UDP), and port which we set to 99999 if the traffic is return traffic and the port is above 1024. Obviously the potential for number of rows grows quickly when you consider the addition of port and protocol tracking per IP.

Regular maintenance[edit]

Check RAID array
archive data from database

archive_daily.pl 2012 09

This will archive data for the given year and month from the daily summary tables. Generally we want to have a year of history in the database.

archive_15min.pl 2012 09

This will archive data for the given year and month from the 15min-increment tables. Generally, we want to have 6 months of history in the database.

if space becomes tight, move flow files and exported data to a backup server, both located in /usr/home/flowbin/archive and /usr/home/exported, respectively

Slaving[edit]

If we were going to setup traffic database slaving (we don't do this anymore), perhaps cause the bwdb machine gets busy and it cannot handle traffic requests and netflow, here's how it's done:

On the traffic master:

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'10.1.4.8' IDENTIFIED BY 'qERUG8wf';

in my.cnf:

bin-log
server-id=1
max_binlog_size=500M
expire_logs_days = 3

on slave: in my.cnf:

server-id       = 2
master-host     =   10.1.4.203
master-user     =   repl
master-password =   qERUG8wf
master-connect-retry=60
replicate-wild-do-table=traffic.daily%
max_relay_log_size=500M
expire_logs_days = 3

replicate-wild-do-table=traffic.%

on master:

touch /usr/home/working/.lock

(make sure processflows not running)

FLUSH TABLES WITH READ LOCK;
cd /usr/home/database/traffic
tar -czf mysql-traffic-snapshot.tgz ./daily*
(~1G)
SHOW MASTER STATUS;

Compiling from source on AMD64 will not work. So, we use a linux-compiled version and rely on linux compat. Linux compat won't install on 8.x - libtool 2.4 need. So, instead we copy(ed) over linux:

cd ../..
chown -R bb .
su bb
cd
cd bbc1.9e-btf
./runbb.sh start

chmod +x /usr/local/etc/rc.d/bb.sh

If this is at i2b, punch a hole in the firewall to allow it to communicate with bb monitor:

ipfw add 00096 allow tcp from 66.181.18.0/27 to 69.55.230.2

configure bb on mail

Copy over the backup script:

scp backup2:/d4/bin/freebsd8.x/rsync.backup /usr/local/etc/

Edit rsync.backup and change config var to point to correct config file location: /usr/local/etc/backup.config

We notice that sometimes flow-capture is failing due to swap exhaustion (even after adding more swap). So we crontab flow-capture to restart (it's ok to start if it's already running, it just quits):

crontab -e

setup traffic db[edit]

Install mysql:

cd /usr/ports/databases/mysql50-server
make install clean

cat >> /etc/rc.conf
mysql_enable="YES"

Move db data dir:

/usr/local/etc/rc.d/mysql-server stop
mkdir /usr/home/database/
mv /var/db/mysql/* /usr/home/database/
chown -R mysql:mysql /usr/home/database

Edit database location in startup script:

vi /usr/local/etc/rc.d/mysql-server
# : ${mysql_dbdir="/var/db/mysql"}
: ${mysql_dbdir="/usr/home/database"}

/usr/local/etc/rc.d/mysql-server start

Install mysql perl database modules:

cd /usr/ports/databases/p5-DBI
make install clean
cd /usr/ports/databases/p5-DBD-mysql50
make install clean
(no to SSL support)

Setting up database

rehash
/usr/local/etc/rc.d/mysql-server start
mysql -u root
create database traffic;
grant all on *.* to root@localhost identified by '5over3';
grant all on traffic.* to jc@10.1.4.5 identified by '2gMKY3Wt';

If this was a new server we'd setup new tables. See mysql for how those tables would be setup.

We are assuming here we are moving data from an existing db, here's how that's done (from the current traffic db):

rsync -av --progress /usr/home/database/traffic/ 10.1.4.203:/usr/home/database/traffic/

When you're ready to do the cutover, shut down mysql on both hosts and do one last sync.

process flows from bwdb2[edit]

On traffic database server (bwdb):

crontab -e
#import sql from bwdb2
10,25,40,55 * * * * /usr/home/flowbin/processsql.pl

Add access to mysql:

mysql -u root -p 
grant all on traffic.* to bwdb2@localhost identified by 's1lver4d';

Make sure bwdb is reachable from the outside only to bwdb2:

On nat, add to /etc/ipnat.rules

# bwdb
bimap fxp0 10.1.4.203/32 -> 69.55.233.199/32

Reload:

ipnat -C -F -f /etc/ipnat.rules

Setup firewall rule on firewall:

ipfw add 00094 allow ip from 66.181.18.5 to 69.55.233.199 22
ipfw add 00094 deny ip from any to 69.55.233.199

Setup firewall on bwdb to restrict access now that it's nat'd:

cat >> /usr/local/etc/rc.d/boot.sh
ipfw add 1 allow tcp from any to any established
ipfw add 2 allow ip from 10.1.4.0/24,66.181.18.5,69.55.233.195 to me 22
ipfw add 3 allow ip from 10.1.4.5 to me 3306

ipfw add 9 allow udp from 10.1.4.5 to me 161
ipfw add 100 deny ip from any to me

chmod 0700 /usr/local/etc/rc.d/boot.sh

From bwdb2, add ssh key:

cat /root/.ssh/id_dsa.pub | ssh 69.55.233.199 'cat - >> /root/.ssh/authorized_keys'

Confirm no password access:

ssh 69.55.233.199 hostname

bwdb2[edit]

Summary[edit]

This machine tracks and stores network traffic (netflow) at i2b. It is our means to monitor customer bandwidth usage.

Location: i2b, cab6
OS: FreeBSD 6.4 x86
Networking: Priv IP: 10.1.2.4 There are 2 onboard nic's, one of which is the "listener"
Hardware: Custom 2U. Single power supply.
Drives: two 150 GB (2 x 150GB) RAID1 arrays running on a 3ware 7006 RAID card.

Services Provided[edit]

netflow
bigbrother

netflow[edit]

The main function of this server is to run netflow on an eth device in promiscuous mode so as to hear everything happening on the port (wherein all network traffic is mirrored to that port via the cisco swith). Every 15min, it creates a flow file under /usr/home/flows/ (organized by date). The flow file contains all traffic data for a 15min increment of time.

A cronjob moves that flow file (or files if there are multiple due to some delay)

1,16,31,46 * * * * /usr/home/flowbin/queue.pl

into a processing queue: /usr/home/working

Then a separate file processes whatever flow files it finds there, and builds sql files ready for insertion into the traffic database:

2,17,32,47 * * * * /usr/home/flowbin/processflows-sql.pl

Then yet another process copies the sql files to the traffic database server for processing and insertion into the mysql database:

8,23,38,53 * * * * /usr/home/flowbin/sendsql.pl

Regular maintenance[edit]

Check RAID array

if space becomes tight, move sql files and flow files to backup server, both located in /usr/home/flowbin/archive

firewall (newgateway)[edit]

Summary[edit]

This machine is the primary (only) firewall for the entire network at castle.

Location: castle, cab 3-8
OS: FreeBSD 4.11 x86
Networking: Priv IP: 10.1.4.223, Pub IPs: 69.55.233.164 (external), 69.55.233.156 (internal). It has 3 network connections (2 onboard, 1 PCI) connecting to the external, internal and private networks. If you're looking at the back of the server, the internal-network-facing nic is on the right (em1), and the external-facing-network (3750) is on the left (em0).
Hardware: 6 SCSI SCA drive bays (2 columns of 3, drive 0 top left, drive 1 just below) all hot-swap. Dual power supply.
Drives: 36 GB (2 x 36GB) RAID1 array running on an Adaptec 2120S PCI RAID card.

Firewall Rule Configuration[edit]

See Firewall Rule Configuration for more discussion on how to actually manipulate firewall rules.

Disaster Recovery[edit]

If there is ever an outage with the firewall, the old firewall "gate" is located just below and is running with the proper network configuration, but with no firewall rules in place (to facilitate good throughput). Have castle move the cable on the left on the current firewall to the left port in the old firewall and the right cable to the right port.

Here's what you need to put in /etc/rc.conf to get a firewall going (as far as routes and IPs)

Reset counters and remove pipe rules on the 1st of the month. Pay attention when setting up a rule as 3 4 5 (that's not a temporary traffic cap).

Inside /etc/daily.local you will see a call to /etc/makepiperules.pl This script will create /etc/firewall.sh which contains all the firewall and pipe rules in place at the time the script was run.

DOS attacks[edit]

See Handling a DoS attack regarding how to handle a DOS attack.

Theres a background process (running from user shell) that monitors the firewall for incoming UDP DoS attacks. When it notices packets above a certain level it will

enter a rule that allows all UDP to go through
send an emergency email to support and indicating an attack is in progress
send an email to castle (nocstaff@castleaccess.com and jcsupport@castleaccess.com) telling them to investigate and put up a null if warranted
wait for a couple minutes to see if the attack subsides- if so it will remove the pass-all UDP rule, if not it will repeat the process from #1

This file lives under /usr/home/user/doswatch.pl To run:

cd /usr/home/user
./doswatch.pl &

To kill;

fg
^C

It writes its findings to /usr/home/user/doswatch.log

backup1[edit]

Summary[edit]

This machine acts as the primary backup location for all VPS-based customers. No customer directly accesses this server to perform their backups. We also store cancelled customers on this server.

Location: castle, cab 3-8
OS: Ubuntu 8.04.1 server x86
Networking: Priv IP: 10.1.4.8, Pub IP: 69.55.230.11 (firewalled from all but JC infrastructure @ i2b)
Hardware: 6 SATA drive bays (2 columns of 3, drive 0 top left, drive 1 just below) all hot-swap. Single power supply.
Drives: 4.5 TB (6 x 1TB) RAID5 array running on a 3ware 9650SE-8LPML (8-port) card

Services provided[edit]

backup via rsync
mysql - traffic data
nfs server - for backups
snmp client - for big brother
bigbrother client

Usage and Notes[edit]

all data is stored under /data
virtually all jc infrastructure, and all VPS machines are setup to mount to backup1 via nfs (mountpoint: /backup1), and they all have their ssh keys setup to allow passwordless rsync's
each virt or jail backs up each evening to backup1. Each server has it's own directory (named for the server). Under those directories are 7 daily snapshots (0-6)
at the time of writing, the mysql server running here is replicating from (slave to) the mysql instance on bwdb. Requests for bandwidth data usage for customers (coming from management, account manager, and accounting scripts running on mail) all direct towards the database "traffic" running on this server.
cancelled customer systems are compressed and stored under /data/deprecated
archived bwdb2 flow files are stored under /data/bwdb2
critical files from backup2 are stored under /data/backup2

Cronjobs[edit]

00 5 * * * /usr/local/sbin/backupwatch.pl 2>&1 > /dev/null
35 5 * * * /usr/local/sbin/usage_check; /usr/local/sbin/snapshot_archive; /usr/local/sbin/snapshot_rotate  /data/backuplog.log

this runs daily the scripts to report on how much disk space each customer system occupies and how long their backups took. Then it rotates backups for each system, removing the oldest backup. It will email support@johncompanies.com at it’s conclusion. This email can be deleted, however note when it begins to take significantly longer to complete, ie runs past 2200 pm – this usually indicates a problem on the backup server.

10,25,40,55 * * * * /usr/local/sbin/processsql.pl

this processes prepared sql command files sent from/by bwdb2 (@ i2b) and imports them into the traffic database.

0 0 * * * /usr/local/sbin/3wraidchk

backup2[edit]

Summary[edit]

THIS SERVER IS OUT OF SERVICE AND REPLACED BY BACKUP4

This machine is used for archiving data and is a backup server for colo customers. It was the former primary backup location for all VPS-based customers before backup1 was installed. Only dedicated customers directly accesses this server to perform their backups. NOTE: power button is broken, so the reset button (paper clip) was rewired to be the power button.

Location: castle, cab 3-7
OS: FreeBSD 6.1 x86
Networking: Priv IP: 10.1.4.3, Pub IP: 69.55.230.10 (firewalled from all but JC infrastructure @ i2b)
Hardware: 16 IDE drive bays (4 columns of 4, drive 0-0 top left, drive 0-1 just to the right TODO) all hot-swap. Triple power supply.
Drives:
- 3ware 7500-8:
  - 200 GB JBOD (1 x 200G) labeled 0-0
  - 500 GB RAID5 (3 x 250G) 0-1 thru 0-3
  - 700 GB RAID5 (4 x 250G) 0-4 thru 0-7
- 3ware 7500-8:
  - 700 GB RAID5 (4 x 250G) 1-0 thru 1-3
  - 700 GB RAID5 (4 x 250G) 1-4 thru 1-7

All drives MUST be western digital IDE drives. Other brands will not fit.

In case of an outage, nfs will hang on all connected servers until the nfs service returns. If you can't get backup2 back online, you can get nfs running elsewhere and fake backup2's MAC's: priv: 00:0e:0c:59:c1:a6, pub: 00:07:e9:5b:c6:45

To configure:

ifconfig fxp0 link 00:90:27:f9:0a:d9

Services provided[edit]

backup via rsync and nfs
samba
nfs
snmp
bigbrother

Usage[edit]

all data is stored under 4 mount points, corresponding to the 4 large RAID5 arrays: /mnt/data1 /mnt/data2 /mnt/data3 /mnt/data4
iso images provided for customers wanting to mount an ISO as a CDROM via the IPKVM are provided via samba on this server. Images live under /mnt/data2/iso
this used to be our primary backup server so you will see old backups from virt and jails around- missing customer data though, just the machine's data
this server serves as an archive for exported db data from bwdb and old flow files.
isys backs up here
customers are nfs-moutned under /mnt/data3/customers as file-backed md devices
in /mnt/data4 there are lots of useful things used for building our vps servers, customer servers, and management scripts:
- /bin: the master repository of scripts and custom binaries we use on jails and virts. Each night every virt and jail rsync's what's in here to update the local files. So any global updates to scripts would need to be made here (or will be overwritten with what's in here)
- /build: files we use for setting up big brother, 3ware cli and scripts for colo's, vzcp customized setup files and so on
- /vzrpms: contains the OS templates for many-to-most of the OS's we offer on vz systems

backup3[edit]

Summary[edit]

This machine is used for archiving data, is a backup server for colo customers, runs a samba server to make available iso's to the IPKVMs, and allows us to connect to the digi serial multiplexer at i2b. Only dedicated customers directly accesses this server to perform their backups.

Location: i2b, cab 6
OS: Ubuntu 10.04.1 server amd64
Networking: Priv IP: 10.1.2.3, Pub IPs: 69.55.229.4 AND 69.55.231.2
Hardware: 16 drive SATA bays (4 columns of 4, drive 0 top left, drive 1 just below) all hot-swap. Dual power supply.
Drives: 5 TB (6 x 1TB) RAID5 array running on an Areca Technology Corp. ARC-1160 16-Port

Moving from one server to another[edit]

Here are the steps you would take to move settings and data from one server to a new backup server:

rsync over all /data/customers (we do this cause if we didn't use *-file it would copy over the files AND the data in the mountpoint)

rsync -av --progress --ignore-times *-file root@10.1.2.33:/data/customers/

after umounting all the customers, copy over the (empty) directories separately:

for f in `find .  -type d`; do rsync -av $f root@69.55.229.25:/data/customers; done

copy mount script

[root@backup3 /data/customers]# scp /etc/nfs_backup_mounts.sh root@69.55.229.25:/etc/nfs_backup_mounts.sh

copy rc.local

[root@backup3 /data/customers]# scp /etc/rc.local root@69.55.229.25:/etc/rc.local

copy /etc/exports

[root@backup3 /data/customers]# scp /etc/exports root@69.55.229.25:/etc/exports

edit /etc/hostname on both machines (set current to oldbackup3)

edit /etc/network/interfaces (swap IPs).

stop mounts from mounting on old and new servers so it doesnt start with reboot right away:

chmod 000 /etc/nfs_backup_mounts.sh

reboot both servers @ same time

check everything out

run /etc/nfs_backup_mounts.sh on new server

if switch port changed update mrtg to reflect correct port pub nic is on (on p20):

vi /usr/local/www/mgmt/mrtg/mrtg1.cfg

console[edit]

Summary[edit]

This box's only purpose is to serve as a means to connect to the digi serial multiplexer boxes at castle. Connect to it using the blue (cisco) ribbon cable with the beige RJ-45 to serial connector, 9600 8N1.

OBSOLETE

Location: castle, cab 3-8
OS: SunOS 5.8 (solaris)
Networking: Priv IP: 10.1.4.4
Hardware: Sun Netra

To connect to consoles, ssh in as user 'console' and use the tip command to connect to devices listed in /etc/remote

SSH WORK ~2021 ssh user@console.johncompanies.com

PW: 674*****

i.e.

tip switch-p1
tip jail1

Configuring digi/ports[edit]

/etc/remote[edit]

This is where the configuration/mapping for ports and custom names which we use along with the tip command to connect to various ports on the digi switches.

We have 2 digi's at castle we connect to:

#3-7 10.1.4.10
virt15:dv=/dev/dty/CO001s:br#38400:el=^C^S^Q^U^D:ie=%$:oe=^D:
virt13:dv=/dev/dty/CO002s:br#115200:el=^C^S^Q^U^D:ie=%$:oe=^D:hf:

and

#3-6 10.1.4.11
jail4:dv=/dev/dty/CP001s:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:hf:
jail16:dv=/dev/dty/CP002s:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:hf:

The only things you need to edit are the first part (i.e. jail4) and the speed (i.e. 9600). You can decipher which port on the digi each line corresponds to by the CP001s or CO001s (port 1 on digi1 and digi2), CP002s or CO002s (port 2 on digi1 and digi2)

drpadmin[edit]

The tool you use to configure a device to a digi box is drpadmin:

bash-2.03$ su
Password:
# drpadmin

Please select an option (a)dd (d)elete (s)how (r)eset (q)uit : s

Please select an option (a)dd (d)elete (s)how (r)eset (q)uit :

Use those commands above to modify the devices available.

Switching IP/hostname[edit]

Edit:

/etc/defaultrouter
/etc/hosts
/etc/hostname.hme0
/etc/nodename
Maybe needed to run: # ifconfig hme0 10.1.4.4 up

devweb[edit]

We do web development on devweb.johncompanies.com

Currently this is a jail running on jail17 / 69.55.230.8

If the jail is restarted, you will need to manually restart the web service with:

httpsdctl restart

All website development work should be done here first. It works exactly like and is setup like our main site.

firewall2[edit]

Summary[edit]

This machine is the primary firewall for the entire network at i2b. firewall3 is a hot standby replacement for firewall2. Both firewall2 and firewall3 should not be connected at the same time since they use the same internal and external IP addresses.

Location: i2b, cab 6
OS: FreeBSD 6.4 x86
Networking: Priv IP: 10.1.2.2, Pub IPs: 66.181.18.3 (external), 69.55.229.1 & 69.55.231.1 (internal). It has 3 network connections (2 onboard, 1 PCI) connecting to the external, internal and private networks. TODO: describe NIC location/orientation

Hardware: 2 SCSI SCA drive bays (2 columns of 3, drive 0 top left, drive 1 just below) all hot-swap. Dual power supply.
Drives: 73 GB (2 x 73GB) RAID1 array running on an LSI MegaRAID SCSI 320 PCI RAID card.

OS: FreeBSD 9.1 amd64
Networking: Priv IP: 10.1.2.5, Pub IPs: 66.181.18.3 (external), 69.55.229.1 & 69.55.231.1 (internal). It has 3 network connections (2 onboard, 1 PCI) connecting to the external, internal and private networks.


The internal network NIC is the left one on the motherboard (69.55.229.1/24, ...).
The external network NIC is the right one on the motherboard (66.181.18.3/28).
The PCI ethernet card is connected to our private network (10.1.2.5/24).

Hardware: 2 SCSI SCA drive bays (2 columns of 3, drive 0 top left, drive 1 just below) all hot-swap. Dual power supply.
Drives: 160 GB (2 x 160GB) RAID1 array running on an LSI MegaRAID SCSI 320 PCI RAID card.

Firewall Rule Configuration[edit]

See Firewall Rule Configuration for more discussion on how to actually manipulate firewall rules.

Disaster Recovery[edit]

To put the backup firewall3 into service:

Move the internal cable (to our networks) from firewall2 to em1 which is the left most ethernet port (69.55.229.1).
Move the external cable (to outside world) from firewall2 to em0 which is the port to the right on the motherboard (66.181.18.3).
The PCI ethernet port (fxp0) should already be connected to private network (10.1.2.5).

DOS attacks[edit]

See Handling a DoS attack regarding how to handle a DOS attack.

build[edit]

partition map:
/ 58g
swap 4g
/var 512m
/tmp 512m
/usr 5.5g

4. edit /etc/make.conf 
echo "WITHOUT_X11=yes \
KERNCONF=firewall3 \
BOOT_COMCONSOLE_SPEED=115200" >> /etc/make.conf

5. add settings to /boot/loader.conf and /boot.config

echo "-Dh" >> /boot.config

echo 'console="comconsole,vidconsole" \
boot_multicons="YES" \
boot_serial="YES" \
comconsole_speed="115200"' >> /boot/loader.conf


6. turn off all ttyv's except 0 and 1 in /etc/ttys
also turn on ttyd0, change type to vt100:
vi /etc/ttys

ttyv2   "/usr/libexec/getty Pc"         cons25  off secure
ttyv3   "/usr/libexec/getty Pc"         cons25  off secure
ttyv4   "/usr/libexec/getty Pc"         cons25  off secure
ttyv5   "/usr/libexec/getty Pc"         cons25  off secure
ttyv6   "/usr/libexec/getty Pc"         cons25  off secure
ttyv7   "/usr/libexec/getty Pc"         cons25  off secure
# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0   "/usr/libexec/getty std.9600"   vt100   on  secure

kill -1 1

on console server:
vi /etc/remote
(rename port to jail8 depending on where and which digi plugged into)
test serial console


7. populate hosts
echo "69.55.230.10 backup2" >> /etc/hosts
echo "69.55.230.11 backup1" >> /etc/hosts
echo "10.1.2.3 backup3" >> /etc/hosts

8. put key in authorized_keys on backup3
cd
ssh-keygen -t dsa -b 1024 
(default location, leave password blank)

Punch a hole in firewall1 to allow traffic to backup servers @ castle:

ipfw add 99 allow ip from 66.181.18.0/27 to 69.55.230.10 22
ipfw add 95 allow ip from 66.181.18.0/27 to 69.55.230.11 22

cat /root/.ssh/id_dsa.pub | ssh backup3 'cat - >> /root/.ssh/authorized_keys' 
cat /root/.ssh/id_dsa.pub | ssh backup2 'cat - >> /root/.ssh/authorized_keys' 
cat /root/.ssh/id_dsa.pub | ssh backup1 'cat - >> /root/.ssh/authorized_keys' 

confirm that you can ssh to backup3 and backup 2 without getting a login prompt

ssh backup3 hostname

ssh backup2 hostname

ssh backup1 hostname


10. edit root's path and login script:
vi /root/.cshrc

Change alias entries (add G):
alias la        ls -aG
