Presumably you meant "the file server *shares* (or *exports*) the
/usr/local/bin directory over NFS to several other Solaris 8 machines"
- a file server client NFS-mounts a file system, a file server exports
or shares a file system.
I.e., "/usr/local/bin" is a local file system on the file server.
When I execute ethereal (ethereal -i hme0) on the NFS'd machine, I
get /dev/hme permissions not set. It looks like permissions are valid
I.e., the permissions on "/dev/hme" *on the machine on which you're
running Ethereal* allow you (not root, *you*) to open it for reading
and writing?
If not, then the permissions aren't valid for allowing users to capture
while running Ethereal as themselves - you have to run it as root.
and everything is setup properly. Ethereal runs properly on my file
server.
Then either
1) "/dev/hme" is readable and writable by whoever's running Ethereal
(although that will, I think, not let you capture in promiscuous mode -
which will, I think, mean you won't see outgoing traffic);
2) Ethereal's set-UID to root, and the machine that's mounting
"/usr/local/bin" is mounting it "nosuid" so that the set-UID bit
doesn't have any effect on that machine;
3) you're running it as root on your file server, but not on the
machine that's mounting "/usr/local/bin" over NFS.
What could be the problem on the NFS'd machine? Is ethereal supported
across NFS?
Ethereal has no idea whether it's running from a binary on an NFS
server or not. It works just fine on Solaris 8 when running from an
NFS server (I did that for years when I was working at Network
Appliance).
