Hi,
i have never seen this behavior before, but in my current setup when
people access imap with squirrellmail from first server (WEB), after
successful login there stays a connection in TIME_WAIT stage on the
imap server (MAIL). On my other clusters and also with other imap
clients on this server, no one leaves TIME_WAIT behind.
One can easily leave 100+ opened connections for tracking by clicking
Check mail periodically thus reaching my limit of connections per IP,
causing DOS. :-)
I have:
squirrelmail-1.4.10a
Installed Plugins
1. translate
2. retrieveuserdata
3. spamcop
4. filters
5. message_details
6. delete_move_next
7. change_sqlpass
8. select_range
php-5.2.5
courier-imap-4.0.6
2.6.22-hardened gentoo kernel
every browser
Need i to specify more?
Lines look like:
tcp 0 0 XX.XX.XX.1:143 XX.XX.XX.2:37294
TIME_WAIT -
netstat -apln | grep 143 | grep TIME_WAIT | wc -l
86
And i did click 40+ times on check myself.
after some time it comes back down:
netstat -apln | grep 143 | grep TIME_WAIT | wc -l
36
Please help me get connection from squirrelmail closed properly.
Thank you.
Regards,
M.
