[squid-users] Fwd: Getting a squid clients list

Sun Sep 5 08:59:43 UTC 2021

 Thanks so much Amos, really appreciate it. It also turns out that I did have the squidclient tool on my squid server, it just wasn't in the path :) I ran: squidclient mgr:client_list | grep "Address" and it gave me 28 IPs, then I also ran mgr:info and that too showed "Number of clients accessing cache:  28" which confirmed it as well.However, if you have a couple of minutes, I wanted to clarify one thing regarding the total squid clients that I'm trying to find.Before I was able to run squidclient, I had run a 'netstat -an' and grep'ed for 3128 and ran this in a loop for 4-5 days to get all connections to the proxy. The list of clients resulting from that shows 62. My understanding of squidclient is that it captures all the information since squid was started, which in my case is July 2020, so the client_list from squidclient tool should have had everything that I found from my 4-5 days of netstat, no? What am I missing or not understanding correctly? And more importantly, which source (squidclient or netstat) should be trusted?
Thanks once again-uzee

You just need to adjust the squid.conf of the running Squid to allow 
management access to the machine you are fetching from.

Be aware:
  Make sure that you only use reconfigure and avoid a restart of the 
proxy after making these changes. A restart will erase some or all of 
the info you are looking to find.

With the CLIENT_IP being address of the machine you are going to do the 
fetch from these commands go at the top of squid.conf:

  acl mgr_client src CLIENT_IP
  http_access allow mgr_client
  cachemgr_passwd none client_list

... *reconfigure* (not restart) the proxy.

... run the squidclient fetch you want

.. undo or at least comment out the above settings and reconfigure.
