Lost connection to hardware

Hi all

I've just had an issue with a couple of dtc's that are attached to one of our servers via a hub - I spoke to the site who advised that there were no changes going on at the time. All users connected to the dtc lost there sessions with "connection aborted" message

I checked the local router - could see the devices in the arp cache - couldn't ping

Couldn't ping them from the server

Checked lanadmin to see if any errors, all ok

I could log onto the server remotely

Checked the syslog

May 10 10:26:00 ocd[852]: (200) ERROR: Unable to obtain data from networ
k: system error 232: Connection reset by peer

May 10 10:22:12 ocd[846]: (264) ERROR: Unable to read binary negotiatio
from network: system error 232: Connection reset by peer

The 'ocd' onward connection daemon is used for communication to peripherals

I attempted to hard reset the devices and the hub - no joy - Had to reboot the server , which brought everything back ok

Any help appreciated

Re: Lost connection to hardware

Steve,

We have had problems where we lose connection to the dtc's and looking in netstat -rn we have dynamic routes to the dtc's via the wrong router - normally after a failover from FBS to ISDN. Removing the dynamic routes sorts out our problem.

Don't know if this is of any help.

Hi

Thanks for the reply.

Hmmm ,I should have checked the routing table entries.
