Fixing “RPC: AUTH_GSS upcall timed out.” from dmesg ( Debian and other linux distro)

In case you see this in your dmesg then please read further. The issue is also giving slow connection ( first) time on a NFS share (takes ~30seconds ).

There is a bug (!?) in the NFS client configuration and it runs a module called rpcsec_gss_krb5.

You can check if this module is running with “lsmod”.

Solution : do not load the module :

as root type :

echo blacklist rpcsec_gss_krb5 > /etc/modprobe.d/dist-blacklist.conf

then reboot

Problem solved : fast connection on NFS share and no dmesg error message.

auto mount your NAS share

I have discovered a better way on mounting the NAS shares .

Previously I was using /etc/fstab but this was not very convenient.

So I found “autofs”. It is taking care of automounting the CD/DVD/ external shares (NFS/CIFS, etc) based on the usage. I mean that when you click on the folder then it will mount it , but when not using the mount folder then at a predefined timeout time it will umount it . This is a good feature for me since I wanted to unmount automatically when I do not use that share.

 

So after installing the autofs ( from repository) then you have to configure two files.

 

First is /etc/auto.master. You should put here the timeout setting and the mount directory.

If you have more mounting paths you can put different timeout settings.

My example below:

file:   /etc/auto.master

+auto.master
/mnt/nfsfreenas /etc/auto.misc --timeout 60 --ghost

The second file is /etc/auto.misc . This contain the mount settings ( somehow similar with /etc/fstab file)

My example file here:

file : /etc/auto.misc

bsddataset    -fstype=nfs,soft,sync,rsize=6000,wsize=6000    192.168.1.20:/mnt/data1/bsdshare

So what I have here is a Freenas Unix share on 192.168.1.20 ( bsdshare) that is NFS type.

You can put in this file the CIFS/Samba also or sshfs or other shares. CD/DVD disks work also.

at the end , after updating this two files with your setup please restart the autofs service with

service autofs restart
