Mike Kick start via NFS through multiple routers is much more reliable over TCP than with UDP. I have run in some very strange issues with anaconda and NFS via UDP. I recommend TCP as the default for all RHEL / Centos 4 and 5 builds. I don't believe that --opts=tcp is supported in earlier version is an anaconda.

Maybe this was already known, but anyway, this simplifies finding trees over NFS and can be useful: Assume you have /mnt/nfs and that is accessible as nfs://foosball.example.org/somepath To import all distribution trees under /mnt/nfs and to get the "url" lines set up automatically, all you do is... cobbler import --name=someprefix --mirror=/mnt/nfs --available-as=nfs://foosball.example.org/somepath It does not however add the opts --tcp. What's the reason for the interest in --opts=tcp ? We could perhaps change the default. > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tim French > Sent: Thursday, October 02, 2008 6:11 PM > To: cobbler mailing list > Subject: RH NFS TCP UDP installs > > I know it's not a cobbler question but maybe someone has run into this > prob. > > It seems that RH (and thus cobbler) uses UDP for NFS kickstarts. > > How are folks NFS kickstarting with their Filers using NFS over TCP? > > The official RH line is to use a boot command line option for RH4. > > > Further research shows: > > It look like adding > --opts=tcp to the nfs line in the ks file would works. > > Since the ks file is generated on-the-fly how do I get something that > looks like this > > # INSTALLATION TYPE > nfs --server $nfs_server --dir $nfs_distro_root/$distro --opts=tcp > > > Timothy French <[EMAIL PROTECTED]> > Office of Information Technology, University of Utah > Key fingerprint = 838C F04D AAC8 6D9C 7ED7 2629 925E BF3E 1FD1 826C > This is a bit kludgy, so you might want to rethink why you want to do it. > _______________________________________________ > cobbler mailing list > [email protected] > https://fedorahosted.org/mailman/listinfo/cobbler > > > _______________________________________________ > cobbler mailing list > [email protected] > https://fedorahosted.org/mailman/listinfo/cobbler > _______________________________________________ cobbler mailing list [email protected] https://fedorahosted.org/mailman/listinfo/cobbler _______________________________________________ cobbler mailing list [email protected] https://fedorahosted.org/mailman/listinfo/cobbler
