Re: [squid-users] Squid3 issues

Please outline your scenario in detail. If you are facing problems
about FDs, then I take it that you already have a running instance,
but that your load is quite high to require more than the default 1024
FDs.

Did you get your OS limits changed to more than 1024? I modify my
servers to 65536 whenever I'm running Squid on them.

Please outline your problem in more details, so that we can help you.

Regards
HASSAN

>> Your rant can be summarized as follows:
>>
>> 1.  You are using a OS (and version) which (according to you) has poor documentation or other info.  Ubuntu / Debian are very popular Linux flavours.  As someone who claims to have been a Linux administrator for "several years", haven't you ever come across the FD issue in any situation? Strange!
>>
>> 2.  You are a single man catering to "many" servers, so you don't want to "waste time" with a software that you could not get running on an OS as in #1.  The "we" in my email was meant to be my company.  I personally see over all the installations we have.  No one else as a helping hand.
>>
>> 3.  You find a lot of people complaining that they can't run squid.  But, you ignore a lot of other people (like myself and Jan who responded to your post) who are saying this is a brilliant piece of software.
>>
>> Instead of ranting, I would suggest you change your attitude, and start laying down the problems that you are facing.  Someone from the community will always get back to you, as they have for me in the past.
>>
>> I have no intention of starting a flame war here.  I just want you to calm down, and assure you, Squid in itself is a brilliant piece of code. Remember, this is the same software that serves Wikipedia, and that speaks a lot about how stable this software is.
>>
>> Also, Squid 3.0 is still under active development, and is not suitable for all scenarios.  We use 2.7 because we use it as a forward proxy, and many features available in the 2.x branch have not yet been fully migrated to the 3.x branch.  So, 2.7 suits our scenario more.  Perhaps you can also mention what your scenario is.
>>
>> As for OS, I've seen some people say FreeBSD is one of the best OS for Squid.  But, we ourselves are pretty happy with CentOS 5.x.  So, find out what works for you.  Ubuntu / Debian are also very popular Linux flavours, so I think you need to search some more about how to increase FDs.
