We have two Linux boxes in our Windows environment. They predate me and anyone else still working here, so essentially they sit there largely untouched most of the time.
Recently part of the process they perform has stopped working. The cron logs indicate that one of the boxes fails to mount the other system, claiming permission denied. I noticed on booting that there's actually 2 mounts that fail.
My first question is, how do I go about troubleshooting/resolving this, and I'd be curious to know why this suddenly happened? (As of 7/18 as far as I can tell).
Machine 1 = 10.0.28.3
Machine 2 = 10.0.29.48 (trying to mount to machine 1)
Windows machines can connect to shares that machine 2 cannot mount to.
fstab on Machine 2:
10.0.28.3:/u/apps/mysql /u/mnt/qxxxxxxx/mysql nfs defaults 0 0
/u/mnt/qxxxxxxx/Cxxxxx_Oxxxx_Lxxxx nfs defaults 0 0
//xxx2/ftp /u/mnt/xxx2/ftp smbfs username=xxx2,password=xxx2 0 0
/etc/exports on Machine 1 (that pertain to Machine 2):
