Google "pin NFS ports" for how to fix them for firewalls. Yes, indeed. In fact I don't know why this has only just bitten me; I've been doing the same thing for years without problem. That search turns up so many answers that I don't know where to start, even prefixing the phrase with "gentoo". Most of them seem to date from 10 years ago or more. -- Regards, Peter.

I can't see anything else wrong. I don't see why it shouldn't work, but there's a couple commands I use to debug NFS. They're not *great*, but they work. I haven't used Gentoo in a while so I forget exactly what env-update does, but I assume mounting the network share works successfully and this is just a command that accesses /var. You can use these commands to make the kernel driver output debugging information to dmesg. On the client: > # rpcdebug -m nfs -s all On the server: > # rpcdebug -m nfsd -s all On both sides, if the others don't give useful info, this is for the lower level protocol: > # rpcdebug -m rpc -s all Then, try running the command again. It will spew a lot of info but hopefully you can figure out from it what's going on. -Marco :-) signature.asc Description: This is a digitally signed message part.

[gentoo-user] Debugging NFS mounts
Hello list, My little server needs help with compiling, so I NFS-export /var (which has its own partition) to a chroot on my workstation. I mount all the partitions on both server and workstation. Then when I chroot, env-update hangs for ever. Well, over an hour anyway. Is it possible to export /var in this way? I can't see anything else wrong. -- Regards, Peter.
