[LARTC] Routing for Squid

[Abd. Samad Awang]

hi all,

i'm using squid as a proxy server, and have 2 gateway for internet access,
currently i'm using 1 gateway for the internet access, if that gateway is
down then i have to change it manually the the 2nd gateway.
can anyone help me with the configuration that will automatically switch to
2nd gateway if the 1st gateway is down.

Thanks in advance

/asa

Hi asa,

You can make a script to ping your internet gateway 
every 5 minutes and if it´s down it automatically switch 
the default route do gateway 2. You set a script to run 
x time with cron job.

Hi

try monit (http://www.tildeslash.com/monit/) or mon
(http://www.kernel.org/software/mon/) to test the connectivity with an external
element like google, and control the default gateway of your proxy.

pinging the internal gateway is not so effective.

Hi.

I use squid (2.5.STABLE4) with probing to parent squid's on ISP-side (2
ISP in my case). And also use "weight" parameter for parents.
For first ISP I'v use weight 1, for second 10.
Like this

cache_peer 1.1.1.1 parent 3128 3130 no-delay weight\x10
cache_peer 2.2.2.2 parent 3128 3130 no-delay weight=1

So most requests go via 10-weghted ISP untill it not marked "dead" (see
/var/log/squid/cache.log) or "tcp connection failed". In that case
request will go via second ISP (weight=1).
when 1.1.1.1 "wake ip" :) requests again return in "right way".
