Squid3 problems

jwhostet

Is my thread dead? :(

I have a system on the network that I thought might have been causing squid to go crazy and hang draining internet to a stop.
So I added it to the list that are supposed to bypass proxy but it did not help solve the issue.

Any body have any ideas?

Can you try to include this on squid.sh startup script after line 4.
Remember to do not save squid config on gui while you test.

sysctl kern.ipc.nmbclusters=65536
sysctl kern.ipc.somaxconn=16384
sysctl kern.maxfiles=131072
sysctl kern.maxfilesperproc=104856
sysctl kern.threads.max_threads_per_proc=4096

Hey thanks for getting back to me!! :)

sorry I didn't get back sooner, school got kinda hectic on me for a couple days.

I can definitely try to do that!
One question though, how do i not save squid config on gui?

Thanks again for the help…. I feel repetitive but I do truly mean it!!!!!

do not press save on squid gui after changing rc.d file ;)

Haha…. Oh that makes sense. Thanks for the help I forgot this went on to a second page Till right now. I'll probably start testing that tomorrow and hope things go well to report back with good news!!

jwhostet

Well we are having major ISP issues here at work so it might be a couple days before I can truly test your possible solutions will post back asap with results!

Ok :)

I love squid but i find too many limitations, at least with when i use it in pfsense. (i don't like how it works in other platforms)

What is going on right now is that https pages cannot be access with the squid3 package installed from pfsense.
I can use lusca and it works well with both http and https pages but it's very outdated and is not being updated an maintained anymore.

So i want to update my pfsense platform but i really feel that squid3 is useless if it doesn't allow me to work with https just like lusca and squid 2.7 without using crazy configurations.

Also squid crashes when i set the maximum object size in RAM above about 450 KB.

In fact i assign 32 GB of RAM to PFSense of which 20 GB are for dedicated for Squid RAM caching and the only way to use all that RAM and make it useful is having the maximum limit of at least 512 KB or even 1024KB for objects stored in RAM.

check dns_v4_first option on squid config gui and try again.

Marcellok so you say that i have to set dns_v4_first off or on?

This is a brand new command that i just discovered thanks to you Marcellok
The problem is that in the squid guide it doesn't say all the values, just the default
and talks about this command: –enable-internal-dns

I wonder if i have to stick --enable-internal-dns with all the other squid settings

http://www.squid-cache.org/Doc/config/dns_v4_first/

With the IPv6 Internet being as fast or faster than IPv4 Internet
for most networks Squid prefers to contact websites over IPv6.

This option reverses the order of preference to make Squid contact
dual-stack websites over IPv4 first. Squid will still perform both
IPv6 and IPv4 DNS lookups before connecting.

WARNING:
This option will restrict the situations under which IPv6
connectivity is used (and tested). Hiding network problems
which would otherwise be detected and warned about.

Also do you know what are maximum size for objects in RAM?

Can i safely set 4096 KB as maximum Object size in RAM?

I used to cache in disk objects big as 9 Gigabytes (a full dvd) with lusca and it works, but if i go beyond 512Kilobytes of object size in RAM sometimes quid crashes.

Marcellok do you work for the squid guys or you just work in the squid3 package for pfsense.

If you work for the squid-cache people, can you please import the ultra aggressive caching features of lusca inside squid? Because lusca is actually a tuned up squid.

Thanks for your support!

Well major issues here… first ISP issue then after they finally came back online I find out there is some sort of failover that my GM added me into. So now im limited to 10Mbps till a new card is installed in his failover box. So I might have to scrap my whole setup/squid may just end up being a basic router... Or nothing.

Thanks for all the help, if something changes in the next few days and I get everything I had before back I will try your fix and report back.

Or I will create another post and start over new.

Again thanks!
