restricting access

[trystan macdonald]

Hi,
Does anyone now how to quickly restrict login access to root and informix users without deleting other accounts on the system.
Thanks,
Trystan.

Trystan,

Well, there's the nologin feature of /etc/default/security, but that keeps everyone but root out. For more granularity, you would need to have a global login script (like /etc/profile) and do some sort of checking in there, like for the presence of a file called /etc/justrootandinformix, and do an exit for everyone else.

Hi,

- vipw and add comment sign (or anything else) to username or password for non-administrative users. Remove this later to allow access again.

- edit /etc/profile: check on loginname and exit if different from root,informix,...

- ...

Stay logged in on one terminal, and test login. Don't lock yourself out.

good luck,
Thierry.

Just a little note. Any user id below 100 is for the system. Don't mess with those. If you delete them your system could have a major malfuncion. Don't change their entries in /etc/profile because they need the priviledges they have.

You can set up a file called /var/adm/inetd.sec

This can let you fine tune who can access the system by what protocol and where.

If this is a security issue, you might find the Bastille security hardeninig utility of use. I've included a link.
