Resource management questions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

I am currently exploring two options for resource managing, and wondering whether I am looking in the right spot...

(1) User access

We have a compute server that only some groups of users have access to, since the others' boss didn't chip in. I attempted to disable logins for users without a HOME on the machine by setting

DEFAULT_HOME    no

in /etc/login.defs, but find that HOMEless people can still ssh in. What is the equivalent of the above option for sshd on Arch?

(2) Resource control

On said server, I would like students' jobs to run at a lower priority. In a /etc/security/limits.d/nt-limits.conf file, I set priority limits for the respective groups

@students         -       priority        10

but they still login with default priority value. The system log has nothing relevant. Is this supposed to work, and what does it take to make it?

Cheerio,
Hauke
