[squid-users] Squid Host Logging with rdesktop and Thin Clients

[Jason Sopko]

I was wondering if it is possible to log the hostname of a thin client 
that's using Squid for its proxy. I currently have thin clients running 
a small custom Linux package that boots the kernel, spawns the xwindows 
system and then immediately connects to a Windows 2000 Terminal Server 
via rdesktop. The thin client users run Microsoft Internet Explorer from 
the Windows 2000 Terminal Server and are forced to authenticate with a 
Squid proxy before connecting to the Internet. The usernames are being 
logged fine with Squid, but I'd also like to be able to log the thin 
client that the person is seated in front of, too. Currently, each log 
entry appears from the IP address of the Windows 2000 Terminal Server, 
since that is the host that they are running Internet Explorer from. 
Each thin client has a unique hostname associated with it, by using the 
'-n $hostname' switch in rdesktop. A different hostname is defined for 
each thin client based on its MAC address during boot time. This 
$hostname parameter is used for a software package called IBM Client 
Access, which is essentially a TN3270 terminal emulation package used to 
connect to an AS/400 server. The AS/400 uses the $hostname variable to 
determine which thin client is connecting to it, even though the actual 
program is running on the Windows 2000 Terminal Server. The AS/400 then 
knows which default printer to use for that particular thin client, 
among other settings. What I'd like to do is somehow pass a similar 
parameter to Squid from the thin clients, so that both the username and 
the thin client name were logged. Is this possible, and if so how would 
I go about doing it? Thank you in advance for your help.
