DEar Team,

We had installed Squid3 on Ubuntu 12 . Squid proxy working, but in a day or twice the user unable to internet and we dont what is issue. Please suggest steps so i can troubleshoot. I am trying to solve the issue but it making me tough for me???

Thanks for your support.

If you're the administrator, what have you done/tried so far?? What would you NORMALLY check for server problems? Perhaps the log files, for the system and squid? Any sort of monitoring you have on the server? CPU? Memory? ANYTHING???

As the administrator, and after being registered here for three YEARS now, these should be obvious things to check as at least a first step.

Dear Team,

I finding this error.

=========================
In the squid.conf file DNS has entered.

Also now i added dns entry at resolve.conf file.
======================================================================

Please suggest if anything extra i have to do.

Ok, so you found an error message. You STILL don't provide any details (version of Squid, version/distro of Linux, etc.), and what you posted for a follow-up is not clear.

What do you mean by "file DNS has entered"? WHAT "dns entry at resolve.conf" (hoping that's a typo, since it's "resolv.conf"). You don't say what you're working with, or what exactly you've done, so we have no idea what you might have to do. The Squid forums have dealt with this before...have you looked?

Yes...right....seen it, you posted the same error before. You seem to not be reading what's posted/suggested.

AGAIN:

• You are having a DNS issue.
• You were pointed to a thread on the Squid forums where the problem was encountered/solved.
• Did you read/understand it?
• What do you mean by "file DNS has entered"?
• WHAT "dns entry at resolve.conf"

You STILL aren't answering questions asked of you. Having to guess/ask about each and every point is not pleasant...we can't/won't guess as to what you've done or tried. If you don't want to answer questions asked, there's little point in posting.
