/etc/init.d/pcscd works only at first start.

[Wolf Pichler]

"/etc/init.d/pcscd *" resp. "service pcscd *" works only at first "start".
In all other cases it just does nothing resp. starts one more pcscd.

Examples:

root@liberty:/etc# service pcscd start
root@liberty:/etc# ps -ef|grep pcscd
root 3850 1884 0 16:09 pts/10 00:00:00 /usr/sbin/pcscd

root@liberty:/etc# service pcscd start
root@liberty:/etc# ps -ef|grep pcscd
root 3850 1884 0 16:09 pts/10 00:00:01 /usr/sbin/pcscd
root 5230 1884 0 17:49 pts/10 00:00:00 /usr/sbin/pcscd

root@liberty:/etc# service pcscd stop
root@liberty:/etc# ps -ef|grep pcscd
root 3850 1884 0 16:09 pts/10 00:00:01 /usr/sbin/pcscd
root 5230 1884 0 17:49 pts/10 00:00:00 /usr/sbin/pcscd

root@liberty:/etc# /etc/init.d/pcscd stop
root@liberty:/etc# ps -ef|grep pcscd
root 3850 1884 0 16:09 pts/10 00:00:01 /usr/sbin/pcscd
root 5230 1884 0 17:49 pts/10 00:00:00 /usr/sbin/pcscd

root@liberty:/etc# service pcscd restart
 * Restarting PCSC Lite resource manager pcscd [ OK ]
root@liberty:/etc# ps -ef|grep pcscd
root 3850 1884 0 16:09 pts/10 00:00:01 /usr/sbin/pcscd
root 5230 1884 0 17:49 pts/10 00:00:00 /usr/sbin/pcscd
root 5295 1884 0 17:52 pts/10 00:00:00 /usr/sbin/pcscd

###

The problem is caused by these lines in /etc/init.d/pcscd:

# create $IPCDIR with correct access rights
rm -rf $IPCDIR
mkdir $IPCDIR
chgrp pcscd $IPCDIR
chmod g+w $IPCDIR

Since PIDFILE=$IPCDIR/$NAME.pid it will be deleted by the first of these commands and
"start-stop-daemon" in /etc/init.d/pcscd using option "--pidfile $PIDFILE" can not work anymore.

Commenting the lines above makes the script work as expected (or at least as expected by _me_).

###

Another minor problem is the line "chgrp pcscd $IPCDIR" in the init script: Group pcscd does not exist.
Creating the group myself does not change anything, neither positive nor negative -
except for the fact that the group is then set on $IPCDIR:

wolf@liberty:/run$ ls -ld pcscd
drwxr-xr-x 2 root pcscd 80 Dez 22 17:52 pcscd

wolf@liberty:/run$ ls -l pcscd
total 4
srw-rw-rw- 1 root root 0 Dez 22 17:52 pcscd.comm
-rw-r--r-- 1 root root 6 Dez 22 17:52 pcscd.pid

Since this is my first fault report here I probably made the mistake to assign it to pcsc-cyberjack instead to pcscd => trying to fix it right now ....

[Ludovic Rousseau (ludovic-rousseau-gmail)]

pcscd version 1.8.10-1 should have:
    # create $IPCDIR with correct access rights
    if [ ! -d $IPCDIR ]
    then
        rm -rf $IPCDIR
        mkdir $IPCDIR
    fi
    chmod 0755 $IPCDIR

Maybe you should reinstall your pcscd package.

[Wolf Pichler (w-pichler)]

Wow ....

I figured out that /etc/init.d/pcscd is simply not getting installed by the package although it is contained in pcscd_1.8.10-1ubuntu1_amd64.deb.

This is why I still had an old version of it on my machine.

Since I am no package expert I just can guess that this happens because it is not in the DEBIAN/md5sums file of the package.

So as a workaround one has to copy it manually.

Is there anything I can/should do concerning this bug?

Thanks for the fast response!

This file is a conffile and is not managed like the other files of a package.

A local modification is not overwritten unless explicitly accepted by the admin. I guess you edited the file and refused to upgrade it during the install of a newer version of pcscd.

I will close the bug.

[Wolf Pichler (w-pichler)]

The only way to get /etc/init.d/pcscd installed is to first purge the pcscd package and then install it newly.

The installation process never asks whether or not to overwrite a modified version of the file - neither in Synaptic nor with apt-get on command line
.
Even if I delete /etc/init.d/pcscd and subsequently reinstall pcscd the file it is not going to be installed.

I repeated this several times, it always behaves like this.
