Hi,
How, if possible, do I only show a user's quota limits when he logs into SSH?
For example, I set a soft limit of 10GB on this user, but when he logs in he can see all the limits:
-sh-3.2$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/fluid01-root 38G 36G 530M 99% / /dev/mapper/fluid01-home 48G 15G 30G 34% /home /dev/md0 190M 33M 148M 19% /boot tmpfs 881M 0 881M 0% /dev/shm /dev/mapper/fluid01-cpbackup 203G 184G 9.4G 96% /cpbackup -sh-3.2$
Is it possible to show him only his limits, and for that matter mounted partitions, which in this case is /cpbackup/knocky ?

quota -vls
?

These are not limits, this is a program he can run. Your question sounds like you want to show a certain result (quota) when the user logs in. But that doesn't seem to be what you want. What you likely want is give users a limited shell. Google for "limited shell", "restricted shell" and "jail".

Hi Kai,
I know what the limits are, and that the program he runs is not related to the limits.
Let me re-phrase :)
Is it possible, with CentOS (or Linux), to allow a user to only see his file quotas (user quotas) when he logs in via SSH, instead of the whole server's disk space?
i.e. when the user logs in, and types df -h, I want him to see something like this:
root@knocky:[~]$ df -h Filesystem Size Used Avail Use% Mounted on /cpbackup 20G 15G 4.6G 77% / root@knocky:[~]$
Is this possible?

try to add "df -h" (without quotes) in user/.bashrc but it will show to the user quotas even if he is connected via terminal instead of ssh

Gregory, it will still show the user the whole server's disk usage, and not his own file quotas. Only difference is that it does it automatically @ login.
And I don't want to limit the shell either.

Dave has already given you this answer I think. You are using the wrong command.

Kai, so are you saying I should replace "df -h" with "quota -vls" ?
OR should I completely un-install df?

df does not show quota. quota shows quota. And if you do not want to have the user access to a certain program you have to remove it or prohibit access otherwise (-> restricted shell).

Kai, don't take this the wrong way, but I can see this is going nowhere.
When Bob logs into the server, via SSH, I want him to see how much space he has left. The server uses quotas to limit the user's space, and "df -h" only shows the whole server's disk usage, not the users. Is it possible, with df to show the user's disk usage, or not?

Yes, code your own df utility, but without secure limits to shell or kernel people can get full information on other ways...

No it is not possible to do this with df.
df is not able to show user quotas nor is it possible to limit it to display only the user space available.
Perhaps if you were to create a partition specifically for the user then you could allow them to use df.

du -sh /home/user, perhaps may help.

Good idea :-)... however, the user would still be able to run df -h unless the shell was restricted.

Thanx :)
Your suggestion is probably not a bad idea though, to have an LVM for each user, instead of relying on file quotas. But that would probably have some performance impact then?
I'll test it our in any case

No, no and no again. I told this already several times. I'm at a loss why you didn't get it.

You could just put an alias in their.bashrc... alias df="/path/to/myowndf" Put anything you want in myowndf script/program, like quota -vls... Of course, they could bypass the alias if they really wanted to but... is that really a problem?
