How to log all requests by an app including post data? (Squid?)

I've come across a similar behaviour in squid (this was about 5 years ago - never got to the bottom of it) but in my case it would start slowing down after being up for 2-3 days.

Something like this run from cron should give the required behaviour for it locking up completely (assuming it stops writing to the log files):

 #!/bin/bash

 LOGFILE=/var/log/cache.log
 # you may need to change the above to point to your logfile
 LASTRUN=/var/local/squidcheck
 # above can be whatever - but dir must exist

 if [ ! -f ${LASTRUN} ] ; then
      touch ${LASTRUN}
 fi
 if [ ${LASTRUN} -nt ${LOGFILE} ] ; then
       /usr/sbin/squid -k reload
 fi
 touch ${LASTRUN}

This needs to run as root - so either in the root crontab, or the system crontab...

 */5 * * * * /path/to/shellscript

(note you should not edit the crontab file in place - use crontab -l >copy_ctb to get a copy of the current crontab, edit it, then load the new config using crontab copy_ctb)

Original

From a command prompt:

sudo route add default gw i.p.add.ress eth1

Then, in /etc/network/interfaces, add this line:

up route add default gw i.p.add.ress eth1

Of course, replacing i.p.add.ress with the gateway's IP in both lines.

Edit for new question

If you need to delete a route, just change "add" to "del". Example:

(command) sudo route del default gw 128.0.x.x eth0
(/etc/network/interfaces) up route del default gw 128.0.x.x eth0

You can set a static route for the branch office through the route command as well

route add -net (network_id/prefix) GW (gateway) (interface)
