[ILUG] RE: FTP and other services ceasing to function... (Richard Eibrand)

Hi Richard,
Maybe is it possible that your hub port is set to auto negotiate between 10
and 100 Meg speeds and every so often it is failing to autonegotiate ? That
would explain the eth0: autonegotiation failed, link ok error messages.
Try hard coding the switch port to 10BaseT.
Regards,
Richard.

If you look at http://www.linuxdoc.org and the HOWTO sections you'll see
many HOWTOs on setting up NFS sharing, Sharing Printers, and Setting up a
proxy to the internet.. If you need help, then this list (and the SuSE
