I just change these option only in squid.conf

Defalt was Change to
* http_port -------------------> http_port 3128
* cache_mem-----------------> 8 MB
* cache_dir--------------------> cache_dir usf /var/spool/squid
* cache_accesss_log--------> cache_accesss_log /var/log/squid/access.log
* cache_log-------------------> cache_log /var/log/squid/cache.log
* cache_store_log-----------> cache_log /var/log/squid/store.log
* cache_effective_user-----> cache_effective_user squid
* cache_effective_group---> cache_effective_group squid
* visible_hostname---------> visible_hostname iServer

Any Idea? whats problem?

ym uses another port when entering chat rooms. you can check the squid log files if its denying some port access when you attempt to go into ym chat rooms and then allow it in squid.conf's port acl listing.

hth.

thansk born4linux,
I got YM port from Yahoo Help its 5050-5070, and I enable these port, but still problem here.

Squid is a proxy for http. I'm not sure if yahoo messenger uses http. Try a packet sniffer to be sure.
