On my SLES8 guests I set MTU in /etc/sysconfig/network/ifcfg-eth0 file. This can also be changed with ifconfig command. I hope This Help, Al Schilla State of Minnesota

Our network, hence my linux guests, use an MTU size of 1500. As it turns out, our z/os systems use an MTU size of 1492. We just started using a z/os HTTP server outside the firewall to do reverse proxy inside to our linux guests. When I do not go through the z/OS httpd server, things go swimmingly. I suspect I'm getting retransmit delays with an 8 byte difference in MTU. I'm not sure under SLES8 where to change the MTU size for ETH0 to see if making those match will change the behaviour we are seeing. Anyone know where to tweak this particular thing after the fact? ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
