Re: [suse-security] FW port 113 keeps open
This behaviour is quite normal.

According to /etc/services this is ident-service.

Even if you pop email the server may try to contact
this service. If you simply drop such packets the
retries of the pop-servers takes a while before
it is sending you the mails without such a identification.

If you reject packets on 113, the server knows that
it is senseless to retry and is sending emails instantly.

Hope that helps
