GitHub + Rebasing from upstream/master to origin/master

So, every now and then on a PR I need to rebase and fix things so I can retest etc. – I always forget this so blogging it to remember.

Scenario:

I have a diff on origin/master on my forked repo and I need a rebase from upstream/master (where I forked from).

Process:
Github recommends merging (https://help.github.com/articles/syncing-a-fork/), this is not always the best way. I do the following:

  1. git remote add upstream https://github.com/python/cpython.git
  2. git fetch upstream master
  3. git rebase upstream/master (no space here ‘/’ instead)

I hope this saves you some time as I continually waste time here.

IPv6 Tacacs+ Support (tac_plus)

Recently @ Facebook we found that we required IPv6 access to TACACS for auth (AAA) for the majority of our production Network Equipment. Tacacs+ (tac_plus) is an old daemon released by Cisco in the late 90s. It still works (even at our scale) and the config was doing what we required, so it was decided that we should add IPv6 Support to it to move forwards until we no longer require TACACS for authentication, authorization and accounting.

IPv6 has been added in true dirty 90s C code style via pre-processor macros. The source is publicly available via a GitHub Repository.

This version is based off F4.0.4.19 with the following patches (full history can be seen in the Git Repository):

  • Logging modifications
  • PAM Support
  • MD5 support
  • IPv6 (AF_INET6) Socket Listening

Readme.md has most of the information you require to build the software and I have included RPM .spec files (that have been tested on CentOS 6). The specs generate two RPMS with tacacs+6 relying on the tacacs+ rpm to be installed for libraries and man pages.

RPMS Build on CentOS 6.5 x86_64 + SRC rpms avaliable here: https://cooperlees.com/rpms/

Usage Tips:

  • Do not add listen directives into tac_plus.conf so that each daemon can load the same conf file (for consistency)
  • Logging:
    • /var/log/tac_plus.acct and tac_plus6.acct are where accounting information will go (as well as syslog) – Logrotate time …
    • /var/log/tac_plus.log and tac_plus6.log is where default debug logs will go
  • Configure syslog to send the LOG_LOCAL3 somewhere useful (this will get both tac_plus and tac_plus6 log information)
  • Pid Files will live in /var/run/tac_plus.pid.0.0.0.0 and tac_plus6.pid.::
  • The RPM does not /sbin/chkconfig –add or enable, so be sure to enable the version of tac_plus you require.

Tested Support on Vendor Hardware

  • Arista EoS (4.13.3F): need to use ‘ipv6 host name ::1’ as TACACS conf can’t handle raw IPv6 addresses (lame) 
  • Cisco NXOS (6.0(2)U2(4) [build 6.0(2)U2(3.6)]):
    feature tacacs+
    tacacs-server key 7 “c00p3rIstheMan”
    tacacs-server host a:cafe::1
    tacacs-server host b:b00c::2
    aaa group server tacacs+ TACACS
    server a:cafe::1
    server b:b00c::2
    source-interface Vlan2001 (ensure what IP request will come from)
  • Juniper: >= Junos 13.3R2.7 required for IPv6 Tacacs (Tested on MX)

I know it’s old school code but please feel free to submit bug patches / enhancements. This should allow us to keep this beast running until we can deprecate it’s need …

30 Levels of NAT Lab #2 – Juniper SRX100s

Well, I had the chance again to play with lots of Firewalls, so I did. A customer had ordered > than 30 SRX100s for clustered branch deployments so I took the opportunity to ask for permission to pull 30 of them out of boxes and reproduce my 30 levels of NAT lab. It’s never the same doing it alone so I put the word out to some nerd mates and got Mr Aijay Adams (@aijayadams) and Master Mitch Hewes (@mitcdh) to tag along and enjoy the extremly draining NAT filled day. The day included unboxing, ‘racking’ and cabling, configuring and then packing it all up. It was a long day, especially since we tried to get routing instances to NAT 10 times on each SRX … We were not successful, it seems LT interfaces are not NAT friendly (which is good, cause it’s stupid and I hate NAT).

Here is the logical layout:

Of course, for good measure, a quick video of our fun 🙂

So we set the SRX’s up identically to the PIX501s

Nat Lab 2
(not as neat – Time didn’t allow that :))

The results were similiar to the Cisco’s latency wise, but throughput was what I really expected originally (before I did the Cisco NAT LAB), the SRX100s were able to achieve the full 100mbit through the 30 levels of NAT.

After getting the same level of NAT achieved as the Cisco lab we set out to better it, by using routing-instances and lt interfaces, but it seems NAT from an lt-* interfaces is not supported in Junos (all be it a stupid requirement, still handy to know). If someone can see what I did wrong in the config below I would love to know. We had to call it quits after many hours trying to get the routing-instances to work, but we were so close!
P.S. I know I could of used all the physicals, I did not have enough patch cables !

Here is a screenshot of a traceroute of out NATHELL

Updating Juniper QFabric

The follow post shows output obtained and the  upgrade process performed recently on a clients QFabric system. This output was captured updating from 12.2X30 to 12.2X50 Junos release via a ‘Non Stop Services Upgrade’ (NSSU) method. This method basically is a very conservative approach updating redundant components one at a time.

The overall process is:

  1. Upgrade Director Group
  2. Upgrade QFabric Interconnects
  3. Upgrade each node group
    1. Network Node group (NW-NG-01)
    2. Each redundant server node group (RSNG)
    3. Each server node group (my client did not have any SNGs)

Before Upgrade Backup

All that is required to be backed up is the QFabric configuration file, everything else about the install is the QFabric standard and able to be restored using documented Juniper methods.

To backup the config log into the device and:

  1. Capture the output from ‘show configuration | no-more’

or

  1. ‘show configuration | save QFabric.conf’
    1. Remotely: scp username@x.x.x.x:/pbdata/packages/QFabric.conf

Upgrade Process with Output

Director Group Upgrade

Copy the RPM image to the director to /pbdata/packages. This process takes around 2 hours. We started at 7:15am and finished at 9:15am.

  1. scp FILE.rpm root@x.x.x.x:/pbdata/packages
  2. Log into the DG via the VIP and start the upgrade
  • request system software nonstop-upgrade director-group FILE.rpm
    • Junos looks in /pbdata/packages by default

Director group upgrade complete

Interconnect Upgrade

This process takes around an hour. It will upgrade Junos on each System Control Board (SCB) partition grabbing the code automatically via the FTP running on the active Director Group member. We observed roughly that time starting at 7:15am and finished at 9:15am.

  1. From the DG CLI initiate the config:
  • request system software nonstop-upgrade fabric FILE.rpm

Node Group Upgrades

The NWNG took around an hour (for 4 nodes) and around 40 minutes for a RSNG. This process upgrades a node at a time in the group and updates both slices. Currently there is no command to verify each slice’s version, it is a known issue.

Node Groups tested were 1 Network node group and 2 RSNGs:

  • NW-NG-0
  • RSNG01
  • RSNG02
  1. From the DG CLI initiate the config:
  • request system software nonstop-upgrade node-group GROUP-NAME FILE.rpm

Output:

Conclusion

The NSSU QFabric upgrade is a very simple and well polished process. Apart from being very time consuming, it’s great and I really like how it’s been designed and implemented. It’s quite verbose and keeps the operator well informed, which I like, loving knowing what is actually going on. I also like (some may argue this is bad) the automatic upgrade of each SCB on the Interconnects and each slice on the nodes, saving that extra step post upgrade, but does make rollback harder.

Well done Juniper, this is another great part of the QFabric Solution!

P.s. Just give me a ssh client and automatic system archival.

Juniper SRX Chassis Cluster RG0 Nagios Check

I was required to check (as this customer did not have a trap collector) which node was active for redundancy group 0 on a SRX cluster. So I thought I would check for a SNMP OID that is only presented by the active RG0 node. This script uses snmpwalk and is configured to use SNMP v2c (this can be easily changed). It has been tested on:

  • CentOS 5
  • Junos 11.4R2
  • SNMP v2c

Here is the little hacky shell script:

[bash]
#!/bin/bash

# Cooper Lees <me@cooperlees.com>
# Dirty Cluster RG0 checker
# Lasted Updated: 20120818

HOST=$1
COMMUNITY=$2

if [ "$HOST" == "" ] || [ "$COMMUNITY" == "" ]; then
echo "ERROR: No host or SNMP community specified"
exit 2
fi

SNMPOUTPUT=$(snmpwalk -v 2c -c $COMMUNITY $HOST 1.3.6.1.4.1.2636.3.1.14.1.7)

echo $SNMPOUTPUT | grep "INTEGER: 2" > /dev/null
if [ $? == 0 ]; then
echo "Host $HOST is the Chassis cluster ACTIVE RE"
exit 0
fi

echo $SNMPOUTPUT | grep "No Such Object available on this agent at this OID" > /dev/null
if [ $? == 0 ]; then
echo "Host $HOST is the INACTIVE RE"
exit 2
fi

echo "WTF – Something is not right …"
exit 3
[/bash]

It checks for the “jnxRedundancyState” OID – this OID reports on RE states and is only accurate on Junos routers (e.g. M and MX series etc.).

Enjoy …

VMWare Guest Consoles over a WAN with Latency

Have you ever used the VMWare console over a WAN with latency and it enters multiple key strokes into the console and makes using the console super annoying! It makes me HATE VMWare and want to smash it into 10000 pieces with a baseball bat.

Well the answer is to add a line to your VMs VMX file to allow it to be ‘laggier’. For example the following will give you 2 second between key strokes:

  • keyboard.typematicMinDelay = “2000000”
