Package: autofs
Version: 5.0.7-3
Severity: wishlist
Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
While setting up a new lab based on IPv4 NIS + IPv6 NFSv4 + IPv6 autofs, I
encountered an automount failure with numerical IPv6 address.
Using an FQDN host name with valid AAAA and PTR DNS RRs makes automount work
fine.
I would like to know if FQDN names are mandatory.
Here are the troubleshooting steps I followed before to mail this bug report.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. Numerical IPv6 static mount OK
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# mount -t nfs4 [2001:db8:feb2:10::12]:/home /ahome
root@clnt:/home/etu# ls -lAh /ahome/etu-nis/
total 16K
-rw------- 1 etu-nis etu-nis 385 mai 21 2013 .bash_history
