Unable to Switch User Error - su: no shell

Tuesday, August 19, 2008

We had some users complaining about not being able to switch or substitute user, su. Here is the error message they were receiving: "su: no shell.” At first I thought the users had inadvertently locked out their accounts. But after querying nisplus and checking the file-based users, I didn’t observe any locked accounts. I tried switching to various users from root and received the same error. Then I tried switching user on a different workstation - no problem. The problem was tied to a particular box.

Then we used the truss command to trace the system/lib calls. It pointed to an unexpected access/permission issue. Observed the /usr directory was set to 600. Frankly speaking, the permission problem was somewhat a surprise since it was working fine the previous day. At any rate, changed the permissions and things were back to normal.

Goosh.org - NOT an Official Google Shell

Sunday, June 15, 2008

After reviewing my statistics today, I found a couple referrals from this website, goosh.org. At first, I did not think much of its Spartan appearance (like I have room to talk). But after tinkering with it awhile, I realized it was pretty darn functional. As you can see below, it behaves similar to a UNIX shell.

By the way, the author of the utility states this is NOT an official Google product! As usual, here is an example run.
