Prevent screen(1) from resizing your SecureCRT windows

November 12, 2015freebsd, unixcmp

Have you ever noticed that when you start or reattach screen it resizes every SecureCRT tab you have open to 80 columns?

There’s an extremely easy fix. First, find out which term you are using. This must be done outside of screen or your term is simply screen.

[cmp@server ~]$ echo $TERM
vt100

Then add the following line to your ~/.screenrc file, adjusting for your term, as needed:

termcapinfo vt100* 'is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;4;6l'

For xterm, you’d replace vt100 with xterm.

Your terminal will now be the width of your SecureCRT window.

Fixing Postfix permissions on FreeBSD

October 4, 2015freebsd, postfix, unixcmp

I recently ran into issues with Postfix not being able to create files in the mail queue because of a permissions problem. Postfix was installed via pkg so it’s a bit perplexing that the permissions were not set as part of the install process. This was inside a jail, but I don’t see how that should make a difference. Here’s the error I was seeing in /var/log/maillog:

Oct  2 15:36:25 monitor postfix/postdrop[20795]: warning: mail_queue_enter: create file maildrop/615300.20795: Permission denied
Oct  2 15:36:29 monitor postfix/postdrop[20823]: warning: mail_queue_enter: create file maildrop/695303.20823: Permission denied

Here’s how I fixed it:

/usr/sbin/service postfix stop
/usr/bin/killall -9 postdrop
/usr/bin/chgrp -R maildrop /var/spool/postfix/public
/usr/bin/chgrp -R maildrop /var/spool/postfix/maildrop/
/usr/local/sbin/postfix set-permissions 
/usr/local/sbin/postfix check
/usr/sbin/service postfix start

Juniper BGP path selection

June 24, 2015junipercmp

Verify that the next hop can be resolved.
Choose the path with the lowest preference value (routing protocol process preference).
Prefer the path with higher local preference. For non-BGP paths, choose the path with the lowest preference2 value.
If the accumulated interior gateway protocol (AIGP) attribute is enabled, prefer the path with the lower AIGP attribute.
Prefer the path with the shortest autonomous system (AS) path value.
Prefer the route with the lower origin code. Routes learned from an IGP have a lower origin code than those learned from an exterior gateway protocol (EGP), and both have lower origin codes than incomplete routes (routes whose origin is unknown).
Prefer the path with the lowest multiple exit discriminator (MED) metric.
Prefer strictly internal paths, which include IGP routes and locally generated routes (static, direct, local, and so forth).
Prefer strictly external BGP (EBGP) paths over external paths learned through internal BGP (IBGP) sessions.
Prefer the path whose next hop is resolved through the IGP route with the lowest metric.
If both paths are external, prefer the currently active path to minimize route-flapping.
Prefer a primary route over a secondary route. A primary route is one that belongs to the routing table. A secondary route is one that is added to the routing table through an export policy.
Prefer the path from the peer with the lowest router ID. For any path with an originator ID attribute, substitute the originator ID for the router ID during router ID comparison.
Prefer the path with the shortest cluster list length. The length is 0 for no list.
Prefer the path from the peer with the lowest peer IP address.

Cisco BGP path selection

June 24, 2015ciscocmp

Prefer the path with the highest WEIGHT. (Weight is a Cisco-proprietary attribute and is non-transitive)
Prefer the path with the highest LOCAL_PREF. (Default value is 100 and is non-transitive)
Prefer the path that was locally originated via a network or aggregate BGP sub-command or through redistribution from an IGP.
Prefer the path with the shortest AS_PATH.
Prefer the path with the lowest origin type.
Prefer the path with the lowest multi-exit discriminator (MED).
Prefer eBGP over iBGP paths.
Prefer the path with the lowest IGP metric to the BGP next hop.
Determine if multiple paths require installation in the routing table for BGP Multipath.
When both paths are external, prefer the path that was received first (the oldest one).
Prefer the route that comes from the BGP router with the lowest router ID.
If the originator or router ID is the same for multiple paths, prefer the path with the minimum cluster list length.
Prefer the path that comes from the lowest neighbor address.

Fixing your Juniper SRX branch series boot partition

July 19, 2014junipercmp

A recent storm caused us to lose power and the next time I logged in into my SRX100H2 home router, I was greeted with this warning:

***********************************************************************

Luckily, the fix was easy and kudos to Juniper for implementing the two-partition system. Here’s the fix:

request system snapshot slice alternate

To verify the procedure, issue the following command:

show system snapshot media internal

The results should look something like this:
