OLD ENTRY: It's been a week already since I was able to use pidgin to login to the Yahoo network on my Ubuntu installation. There seems to be a problem with the scs.msg.yahoo.com. To fix this problem, go to Accounts -> Manage Accounts then select the Yahoo account then click on Modify. Go to the Advanced tab and set Pager server to cn.scs.msg.yahoo.com. Click on Save and restart Pidgin.
