To those linux-OS users with Pidgin as their IM messenger application, or even those with Windows... this might be useful if you have troubles connecting with your Yahoo accounts.
Just noticed that after the latest patch release by Ubuntu, which includes an update to Pidgin... I had this unusual trouble of trying to connect to my Yahoo messenger account. After reading some forum helpdesk sites of Ubuntu, it was indeed also experienced by some users. Apparently, the latest version has an "isolated" case of having trouble connecting to scs.msg.yahoo.com. To try and fix this problem, just "edit" your account profile and go to the advanced tab where the network details of yahoo are placed. Replaced scs.msg.yahoo.com with the direct IP address, which is "184.108.40.206".
This fix worked for me after being applied. Hope this helps...
