Hi.

I've got a Haupage BT878 ImpactVCB card and can get video to stream using xawtv.

When I add a monitor to ZM, it adds the monitor, but video doesn't come in.

I've looked at the logs. The zmwatch.log file contains a message

02/27/06 09:33:01.024119 zmwatch[16637].ERR [Can't get shared memory id '7a6d2006', 6: No such file or directory]
02/27/06 09:33:01.024499 zmwatch[16637].INF [Restarting capture daemon for Vid1_2, shared memory not valid]
02/27/06 09:33:01.261404 zmwatch[16637].INF ['zmc -d /dev/video1' stopping at 06/02/27 09:33:01]

Any idea what I need to do to get this monitor to work?

Thanks,

Bruce

You will almost certainly find other error messages in /var/log/messages so if you haven't checked already I would look there.

Here is some information from messages file:

It appears that the "su" command for apache is failing as well?

Please help.

Can you tell us what distro you are using? It is likely that you will have to edit /etc/passwd and give the apache user a login shell I think. This should be addressed in 1.22.1 so you don't have to do this.

Distribution is 1.22.0 on SUSE Linux 10.0 Kernel 2.6.13.

I've created an "apache" account manually (useradd) and placed it in an apache group with a login directory. I also set the suid for the zmpkg.pl script and changed the owner to root in order to get the "su" command prefix to work.

What else should I do? I really want to get this to work.

Thanks ahead of time.

Are you saying that the su command works now? If so then is something else failing? If not then you need to make sure your apache user has a login shell specified in /etc/passwd.

Phil,

It turns out that the permission on /tmp/zmdc.sock was not writable by "others" and "group". When I set these, things seem to work.

Question for you ... every time I reset the zmpkg.pl restart, I need to do a chmod on /tmp/zmdc.sock to allow write permission for others and group. How can I avoid this?

Thanks.

I have to say that I don't know. It should be created by the script so the script should be able to delete itm which it will do on normal shutdown as well as on startup.
