ZM 1.22.0 Problems with shared memory. And su.

[r0y]

Hi i've got some problems with 1.22.0 here are the erros:

Feb 7 13:56:47 surveilance zmpkg[21249]: ERR [Unable to find valid 'su' syntax]

And lots of these:

Feb 7 13:58:26 surveilance zmu[21340]: ERR [Can't shmget, probably not enough shared memory space free: Invalid argument]

I've tryed to increase memory now its:

shmall: 154217728
shmmax: 154217728

How much memory do i have to set here and how to fix the invalid syntax?

Can you tell us what distro you are using?

[r0y]

Sorry, its a fresh gentoo install.

Any one got a ide? I need to get this setup up and running becasue i want to se if those ppl in the appartment downstairs are stealing food from us.. hehe

My best advice: use a more thoroughly tested Linux distribution as your plattform. I'm using Fedora Core 4 and it works wonderfully. Only took me 2 hours to set everything up from scratch.

And with Cordel's RPM, it should be even a quicker install!

There are plenty of people running ZM on gentoo so I'm a little surprised why you are getting the su error. Can you edit your installed zmpkg.pl and change the value of DBG_LEVEL to 1. Then try and start ZM and post the relevant parts of your zmpkg.log file.

Well i don't like RedHat/Fedora, and found that the only distro i like is gentoo, i did however try the Livecd but i didn't get any picture. And all of my computers witch is runnig linux is running gentoo

Ok with debug level 1 here it is:

su apache -c 'true'
su apache --shell=/bin/sh --command='true''

Can you try those two commands interactively and post what you get.

[r0y]

I tihnk i know whats wrong

su apache --shell=/bin/sh --command='true'' <- one too many of '

Here is goes:

surveilance zoneminder # su apache -c 'true'
surveilance zoneminder # su apache --shell=/bin/sh --command='true''
>

surveilance zoneminder # su apache --shell=/bin/sh --command='true'
surveilance zoneminder #

[zoneminder]

I think that was just me making a cut'n'paste typo. Actually what we need to know is whwther the command succeeded, so try this

Code: Select all

su apache -c 'true'
echo $?

su apache --shell=/bin/sh --command='true'
echo $?

[lazyleopard]

The apache user may need a shell defined? The default Gentoo install sets apache's shell to /bin/false.

[zoneminder]

Yes, I think I'll change this for 1.22.1 to fork and exec instead.

[r0y]

Thats nice, but any workarounds now? Cause i really need this up and running

[lazyleopard]

Try using vipw to edit /etc/passwd, changing

Code: Select all

apache:x:81:81:apache:/www:/bin/false

to

Code: Select all

apache:x:81:81:apache:/www:/bin/bash
