Hi Renato, I tried that. Prints a lot of information. It doesn't reference anything in regards to the username logged on as. Would I know split that info and do a lookup in the access.log file? -----Original Message----- From: Renato Policani [mailto:RenatoPolicani@xxxxxxxxxxxx] Sent: 30 March 2005 05:52 PM To: Douglas Lane; squid-users@xxxxxxxxxxxxxxx Subject: RES: [squid-users] Determining "who is online" Hi, Use /usr/sbin/lsof -i | grep squid [ ]´s Renato Policani. -----Mensagem original----- De: Douglas Lane [mailto:doug@xxxxxxxxxxxxxxxx] Enviada em: quarta-feira, 30 de março de 2005 12:06 Para: squid-users@xxxxxxxxxxxxxxx Assunto: [squid-users] Determining "who is online" Hi all, I am looking for a solution that will allow me to see "who is online" using my proxy server. The proxy server is setup to use authentication. What I want is a utility that will show me who is logged onto the squid server with their username and ip address. I suppose I could build a script that monitors the access.log file pulling all the user names, and then matching up an IP address, and finally showing it on the console. But how accurate would it be? How would I know when someone stops accessing it? Or should I then match the IP address from the log file to a "netstat -na | grep :3128" and establish whether the client is online or offline. Any ideas? Or anyone know of a program? All help is appreciated!
