With all the VPS's I have, if you login and do a w to see who is logged in, it always says there are 0 users logged in -- even if there are 5 users on.


07:10:57 up 17:27, 0 users, load average: 0.00, 0.00, 0.00
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT


any way to fix this to properly display who is logged in?

Can you please file a bug report for that? It looks like this is a bug somewhere... Do not forget to specify your arch and template.

If you would find a submitted bug report in red hat's bugzilla or somewhere else that would be nice. Or just submit a bug report to RH yourself...

I have fixed this issue with a custom kernel, it required two options to be enabled and then custom compiled with rpmbuild.

I have a copy of the following kernel's;

Enterprise
Original
Smp

If you need a copy of any of the above, drop me an email to the address in my signature, and i'll send over a copy of the kernel.

Regards,

Hello,

You have to enable this to 'y';

CONFIG_AUDIT=y

And just underneath the above, copy the following into the kernel config;

CONFIG_AUDITSYSCALL=y

Hope that helps

w command shows only that logins, that are registered in utmp file.
See more information in manpage on utmp.

AFAIK, some implementaitions of openssh and other login-programs create bogus utmp-records or just don't create them.

"vzclt enter" command doesn't create such record. So w shows nothing. But if you login with ssh - here you are - w shows everything.

If it isn't so - it's a bug.

On a fresh CentOS VPS logging in via SSH directly to the VPS itself shows nothing in the 'w' command.

It is because OpenSSH changed something in their latest update, well that's what i heard.

But yeah i tested this on my VPS HostNode and all works fine.

Yeah, I can verify this.

Originally I thought it was an OpenVZ security thing not to report the users.

Logged in via console (as opposed to SSH) and who, finger commands both work fine.

It has been reported earlier in this thread that a Kernel rebuild with the following options enabled fixes this issue:
You have to enable this to 'y';

CONFIG_AUDIT=y

And just underneath the above, copy the following into the kernel config;

CONFIG_AUDITSYSCALL=y

I have added this info as part of a comment to http://bugzilla.openvz.org/show_bug.cgi?id=124

I have rebuilt the latest Kernels here:

http://www.julianyap.com/wiki/Custom_OpenVZ_kernels

Feel free to download them. I have quite a lot of bandwidth.

I am a FOSS advocate so a donation is appreciated to assist in my endeavours.

Feel free to ask any questions or if you want me to put up any explanations.
