Hello, I''m not able to use my serial modem in dom0 (xen-3.0-testing on Fedora Core 3). Using firefox to query a web-site results in keeping the browser querying and I cannot see any sent response in the tcpdump. traceroute tells me, that one of the routers seems to have a problem with packets > 400 byte and everything works fine when I set the mtu size of the ppp interface to 400, but I lose a lot of bandwith. I''ve testet this with other Xen versions (2.0.7 and unstable) and I don''t use a firewall (iptables -F). I don''t have this problem with the same (vanilla) kernel version. The router accepts all packages when I use the default mtu (my provider uses 1492 as default). Any idea what could cause this problem? -Ralf- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
