Have there been any recent physical expansion or wiring topology changes in your external network switches or routers? This kind of symptom is sometimes caused by layer 2 routing or spanning tree loops in the external switch topology, which cause the external network boxes to stop forwarding frames while the switches try to sort out the spanning tree topology. You'd see exactly this kind of thing if that were the case -- traffic will just stop periodically. Are your test systems for SSH and other services that continue to work on the same switch or switches downstream from a common switch? If it's not a spanning-tree problem, or is limited to one protocol only, I'd suspect an external firewall or router ACL. > Traceroute all blanks (* * *). Good reason to not disable ICMP entirely. Tough to debug your network if you can't get useful diagnostics. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
