Hi list,
I have an LTSP environment, which is working fine with kernels before =
2.6.20 series. I think I started to test with 2.6.20-rc3, up to latest =
2.6.20.1, but mounting nfs shares from the clients fails with =
"permission denied". If I reboot server to 2.6.19.x without changing =
configuration, it works again.
When I try to mount /home from my laptop (with kernel 2.6.20), I get the =
well known message:
mount: tiare.sysnux.pf:/home failed, reason given by server: Permission =
denied
But, on the server I have:
[jdg@tiare ~]$ cat /proc/fs/nfs/exports
# Version 1.1
# Path Client(Flags) # IPs
/home =
192.168.10.0/255.255.255.0(rw,insecure,root_squash,sync,wdelay,no_subtree_c=
heck,insecure_locks)
Client and server are based on Mandriva 2007. Server is 64 bits SMP. =
nfs-utils has been updated to 1.0.10. I can provide more details if needed.
I think I have done all checks recommended in the troubleshooting =
section of the nfs-howto. Any help would be greatly appreciated.
Thanks,

Thanks Kevin for very prompt reply, but I can't find that code in =
net/sunrpc/svcsock.c of the 2.6.20.1 kernel. At line 925 I have:
if (!(newsvsk =3D svc_setup_socket(serv, newsock, &err, 0)))
goto failed;
/* make sure that we don't have too many active connections.
Thanks,

That bug was never in mainline, so I doubt that was it. :-)
