I'm using BSD 4.3. I'd like to set something up so that certain users are niced to a given value whenever they login. If possible, I'd like them not to be able to increase their priority, but I could live without this. Any ideas welcome. Jeff Siegal

You can change a users nice value with some special characters in the gecos field of their password entry. Suppose the login entry is: name:password,aging:uid:gid:info:home:shell changing it to: name:password,aging:uid:gid:pri=5 info:home:shell will make their nice value 25 (higher nice but lower priority). changing it to: name:password,aging:uid:gid:pri=-10 info:home:shell will make their nice value 1 (lower nice but higher priority). Some systems set the priority of their uucp logins this way. This was documented in some older versions of UNIX. Try it out in BSD and see if it works. Larry Cipriani cbsck!lvc
