If I try to touch a file which is on NFS mounted directory, I get "Permission denied" despite group I belong to has full access to this file. I can edit and remove the file with no problems, but touch doesn't work. This is rather tricky situation, as compiling code gets quite difficult for this group, as only the owned can touch the file despite the effective permissions on file (and previous directories). -Tuoppi- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

As Neil points out truncated packets do not help, so the trace again
with -s 1500 as an argument to tcpdump:

NFS v2 attribute problem with 2.2.18?
I just installed the new 2.2.18 kernel and I get a strange problem with
NFS v2 servers (for example AIX 4.1.5). The problem does not appear if
the NFS server is a newer V3 for example from Solaris 7. The problem is
that I am unable to create new files in a newly created directory for a
while:
ramses$ /bin/mkdir yyy; /bin/touch yyy/xxx
/bin/touch: yyy/xxx: Permission denied
The permission denied error goes away after a while. I did trace the
above command using tcpdump (I hope this helps to diagnose the
problem):
