-host in auto.master not mounting nfs exports

[dsijbesma]

[SRU justification]

[Impact]

Using the auto.net in auto.master recognizes the nfs shares but unable to cd into the latest directory which contains the actual data.

-host doesn't mount anything

I am having same problem with auto.net. When I try to cd to /net/salmo (one of our servers) I get in syslog:

automount[234566]: key "salmo" not found in map source(s).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Todd Kaehler (todd-kaehler)]

In /etc/auto.master if I change:

/net -hosts

to

/net /etc/auto.net

it works...

[pd5rm (pd5rm)]

I had this problem as well after an upgrade from 14.04 to 14.10.

The workaround suggested in comment #4 works for me. Thanks a lot!

[dsijbesma (dsijbesma)]

Changing the entry

/net -hosts

to

/net /etc/auto.net

in /etc/auto.master does work for me now as well. In the time of
initiating this bug report it wasn't.

This appears to be a bug in the version of autofs that Ubuntu is shipping. See this report from ArchLinux: https://bugs.archlinux.org/task/38379

[Paul Smith (psmith-gnu)]

Also there's a problem reported in Fedora against 5.0.7, but apparently still present for 5.0.8: https://bugzilla.redhat.com/show_bug.cgi?id=1038356

[Dwaine Gonyier (dgonyier)]

Having the same issue, using work around similar to comment #4 works for me.

From an strace of /usr/sbin/automount, the call to RPC portmapper is being made to port 28416 (0x6f00) instead of 111 (0x006f).

I think there's a missing htons() call in there somewhere.

13151 sendto(5, "y!\201\10\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\2\0\0\0\0\0\0\0\0\0\0\0\0"..., 40, 0, {sa_family=AF_INET, sin_port=htons(28416), sin_addr=inet_addr("192.168.2.249")}, 16) = 40

Is there a reason we can't just go get the patches that Ian Kent already provided for Fedora (see my link to the Red Hat bugzilla entry, which contains references to RPM versions that fix the problem) and apply them here and/or in Debian since the bug exists there as well?

[Chris J Arges (arges)]

@xtrusia:

1) Can you make the changelog include the bug it closes for example:
"Fix mount issues when using '-host' in conf file. (LP: #1386869)"

2) Can you ensure the patch is in DEP-3 format:
http://dep.debian.net/deps/dep3/

Thanks,
--chris

[Chris J Arges (arges)]

@xtrusia:
1) The changelog looks good except you should format your name correctly. Use 'Seyeong Kim' instead of 'seyeong.kim'.

2) You still haven't formatted the patch using DEP-3.

[Greg Stachowski (greg-stachowski)]

This bug has now appeared in 14.04 LTS after the upgrade to autofs 5.0.7-3ubuntu3.2 (a couple of weeks ago, it doesn't manifest until autofs was restarted at reboot). The fix in #4 doesn't work. Can we get the 5.0.8-1ubuntu1.2 package backported to 14.04 ASAP? For an LTS release breaking autofs and leaving it without a fix is unacceptable.

[Seyeong Kim (seyeongkim)]

@greg-stachowski

Is it the same after rebooting?

I tested it today, right after installing autofs i could reproduce it

but after rebooting the machine, it works fine

Please check this again

Thanks

[C. Alex. North-Keys (erlkonig-talisman)]

autofs function (5.0.7-3ubuntu3.2) can apparently be broken by enabling DoS features in a TP-LINK TL-SG3424 switch, specifically the one labelled "SYN sPort less 1024". This has turned out to be the problem at my site. I'm not in a position right now to see if higher autofs versions (5.1.1+) have the same weakness, so for now I'm just going to leave that DoS defense disabled.
