Am running an application on Sco Unix but am having the following problem. Application is hunging sporadically. Am accessing the application via telnet.Have changed the link thinking that this could be the problem but to no avail. Have increased keep alives on the routers and increased capacity on them. service tcp-keepalives-in and out.But this has not sorted the problem out. Any thing that i need to be looking at or am missing Thanks
I don't think this is the appropriate list for asking a question about a problem with telnet to a sco box. I don't understand why you think "service tcp-keepalives-in/out" has any effect on traffic to and from a host to a SCO box. This command is for traffic to and from the router itself. Look for errors on the link, double check all routing, in both directions, check masks, gateways, things like that. Fiddling with knobs on the router is likely not the fix, especially the ones you are messing with. Brian On May 27, 2010, at 2:47 PM, jacob miller wrote:

I'm not sure why anyone is running SCO Unix. Call their technical support, enjoy the crickets. Andrew On 05/27/2010 03:01 PM, Brian Feeny wrote:

That seems consistent with my memory of SCO Unix.
Did you remember to get the licence for the TCP/IP stack?
As well as the "don't sue me because I want to stop using them" license? Ask Autozone about that one :) Ken Matlock Network Analyst Exempla Healthcare (303) 467-4671 matlockk@exempla.org -----Original Message----- From: John Peach [mailto:john-nanog@johnpeach.com] Sent: Thursday, May 27, 2010 1:31 PM To: nanog@nanog.org Subject: Re: Hung Telnet Sessions on Sco Unix On Thu, 27 May 2010 21:26:27 +0200 Joe Abley <jabley@hopcount.ca> wrote:

Are your telnet sessions running through a firewall-like device? If so, perhaps the firewall tables are timing out the session after a long enough period of activity? -- Henry Yen Aegis Information Systems, Inc. Senior Systems Programmer Hicksville, New York

Are there any firewalls doing NAT and keeping table entries for inspecting sessions among your "routers"? Check for drops there. -andreas
