Certain Users cannot write to /var/tmp

Steven Sobkowski — Tue, 14 May 2002 19:49:34 GMT

Any help on this would be appreciated:
I have an 11.X System in an NIS environment. The permissions on /var/tmp are correct bin:bin 777 (no sticky bit, even though there should be). There are a number of users that cannot create a file under /var/tmp. Most of the users can and I have been unable to locate any common theme among the users that cannot write to /var/tmp, they simply get a "cannot create" error. Can anyone think of a reason for this to occur?? Of course, there is plenty of space available under /var/tmp.
Thanks for any feedback,
Steven Sobkowski

what is the ownership and permissions on /var? they have to be able to navigate the entire directory path.

/var is also bin:bin and 777, so that looks okay too.

are they having problems with just certain file names or creating any file? it may be that the file they are looking to create is a common file to the application, and may already exist with limited ownership/permissions which is what is restricting their access.

I would check the permissions of the /var mountpoint or /var/tmp if /var/tmp is a separate filesystem. You must unmount the filesystem to check this but this could very easily be your problem.

Thought number two: Are ACL's in play?

Good Question about the ACL's. Unfortunately I am ACL illiterate (and I inherited this machine unwillingly of course). There is a good chance that they are in place, I will start looking at how to find that out, unless someone posts a message and tells me how.

Thanks,
Steve.

check the man pages for acl and lsacl

It doesn't appear ACLs are in play here :(. Also in response to an earlier question, the users having the problem cannot create any file under /var/tmp .. regardless of the name.

Thanks ...

Hi Steven

If the user is trying to create a file which is already there then also u will get this error , may be you can delete all files for that application and restart the same to know if that is not the case.

Just a thought

If this is a vxfs filesystem(which it probably is) then lsacl won't work - that's for hfs filesystems only. getacl /var/tmp will display the ACL's. Man getacl for details.

I would have these same users try to write to another filesystem. If that works then I would definitely look at the mountpoint permissions.

Thanks for all the inputs. I notices that /var was mounted with the quota option. Although there were no quoto's specified for the users having the problems, it turned out that by doing a quotacheck -F vxfs /var mysteriously corrected the problem.

Thanks again ..
Steve.
