Fedora 17: autofs and nfs broken

kromberg · #1 27th January 2013, 08:16 AM

What ports are being used with autofs and nfs? If I have the firewall enable, autofs is not able to mount exported filesystems. With the firewall enabled, I am able to mount the filesystems manually fine. If I disable the firewall, autofs works as expected. When the firewall is enabled, I have nfs set as a trusted service. What other ports do I need to open up? With Fedora 16, things just worked.

No one else is seeing this problem?

Can you show your auto.* mount files and your /etc/exports file? As root, execute netstat-ltp to view the listening ports. Execute rpminfo -p to view portmapper, nfs and mountd processes. And here's a good tutorial on NFS/Autofs configuration.

Looking more into it, it is an issue with autofs or nfs, but the firewall. With it disabled everything works as expected. The ports that system-config-firewall does not open the needed ports any more with Fedora 17. Autofs or nfs is using a new port that system-config-firewall does not open. This is happening on the server side. I can leave the client firewall enabled.

well, i've the same problem with autofs and nfs (nfs4);
it seems a bug: https://bugzilla.redhat.com/show_bug.cgi?id=805252

These are legit bugs but I thought the idea of using automounting was for an "as needed" mounting system. I mount cifs file systems also but not through the client machines fstab as stated in the bug report. I automount my remote cifs file systems through the use of the /etc/auto.* files (master and misc). Then when I want to use files from the remote file systems I cd to /misc/music (for example) and the file system is mounted and files are available. I use the option [--timeour=60] in the master file to make the remote file system umount if the file system is detected as idle or not in use.

someone of them use nfs4 with autofs successifull?

here my /etc/exports:

HTML Code:

/var/run/media/vage/BIG        192.168.1.34(rw,insecure,sync,fsid=0,no_root_squash)

here my /etc/auto.master (on client 192.168.1.34):

HTML Code:

/mnt/BIG	/etc/auto.net4 --timeout 60

here my /etc/auto.net4 (on client 192.168.1.34)

HTML Code:

BIG	-rw,soft,intr,rsize=8192,wsize=8192	192.168.1.35:/

192.168.1.35 is server ip address

here the "mount" output:

HTML Code:

/etc/auto.net4 on /mnt/BIG type autofs (rw,relatime,fd=7,pgrp=5704,timeout=60,minproto=5,maxproto=5,indirect)

and the "ls" command:

ls -l /mnt/BIG
.. (nothing)

many thanks!

Hi friends,
as a result of various difficulties encountered in configuring the service nfs4 on Fedora, I decided to make this tutorial:

The language is Italian, made with LibreOffice Draw, if among you there were those who want to translate it I will be happy to provide the file sources.

ciao
