Unable to mount NFS shares
Hi,
I have a new problem that surfaced after my ISP corrected a connection
problem and apparently changed the assigned IP addresses for each box on
my home network. I corrected the IP addresses and succeeded in
reestablishing ssh, remote desktop, remote printer connections for all
machines and nfs shares on all machines but one; I am unable to mount
nfs shares on my Ubuntu 8.10 box.
Home Network:
Debian Sid, 686 desktop, wired connection
Ubuntu 8.10, 686 desktop, wireless connection
Debian 5.0, laptop, wireless connection
Each is configured as both nfs server and client.
The following files appear to be correct for all:
/etc/hosts
/etc/export
/etc/fstab
Again, I am unable to mount the shares from the Debian Sid box on the
Ubuntu box. The process simply hangs without any output, connection or
termination (until I manually terminate the action). I cannot find any
problems in the log files. Strace output is at the end of this message.
I'd appreciate any suggestions.
Thanks,
Tom Ashley
