I'd had problems dealing with PCMCIA support on my TuxTops 20U laptop,
reported here January 30.
Characteristics were that running 'cardmgr' would produce the following
/var/syslog output:
May 21 00:18:58 ego cardmgr[15743]: starting, version is 3.1.22
May 21 00:18:58 ego cardmgr[15743]: open_sock(socket 0) failed:
Permission denied
May 21 00:18:58 ego cardmgr[15743]: no sockets found!
May 21 00:18:58 ego cardmgr[15743]: exiting
...which had me stymied.
So, I read the manpage *carefully* and note:
At startup, cardmgr requires that /tmp reside on a
filesystem that permits special device files (i.e., a real
linux filesystem, that is not mounted "nodev").
...well, guess what yours truly had had for /tmp -- it's a modest
security precaution.
Just checked -- it *is* possible to mount /tmp 'nodev' *after* cardmgr
is started, so all that's really required is to make sure the partition
(if any) is mounted 'dev' while cardmgr is launched.
I've added the following functions to my /etc/init.d/pcmcia script
(following the "cleanup" function):
# KMSelf -- some functions to check mounting of /tmp and deal with it if
# it's mounted 'nodev'
tmpdevck()
{
if grep -q ' /tmp .*nodev' /proc/mounts; then
echo -e "Hmmm... /tmp is mounted nodev, saving opts... \c"
tmpopts=$( awk '/ \/tmp / { print $4 }' /proc/mounts )
echo "$tmpopts"
fi
}
tmpmntdev()
{
if [ ! -z "$tmpopts" ]; then
echo -e "Remounting /tmp dev... \c"
if mount -o remount,dev /tmp; then
echo "successful"
else echo -e"\aFAILED!"
fi
fi
}
tmpmntrestore()
{
if [ ! -z "$tmpopts" ]; then
echo -e "Remounting /tmp as $tmpopts... \c"
if mount -o remount,$tmpopts /tmp; then
echo "successful"
else echo -e"\aFAILED!"
fi
fi
}
...and invoke them before and after running cardmger in the script:
echo " cardmgr."
tmpdevck
tmpmntdev
/sbin/cardmgr $CARDMGR_OPTS
tmpmntrestore
...which does the trick.
Modify to suite if you don't have /tmp mounted as its own partition.
