What operating system?

------Original Message------ From: Robin Scher To: StudioSysAdmins ReplyTo: discuss@studiosysadmins.com Subject: Problems with TCP Sent: Mar 6, 2010 3:13 AM

Has anyone seen a problem where two machines can communicate on a UDP socket connection just fine but the same two processes on the same two machines fail to connect (connect timeout) when trying to communicate with TCP? Any ideas where to look? The network is a mess, with machines routed through three different switches, but the problem even affects two processes on the same machine trying to connect to each other.

It's very late and I'm really tired so if there is something I'm missing, maybe one of you has an idea or has experienced something similar before?

Thanks for any pointers you may have.
