usermod command changed permissions - Disaster

Team:

I did this command.

usermod -u 209 www (to change the UID of the user www) and it changed every permission on the machine under / recursively.
How do i revert this? How come it changed everything under root directory? Anyone help please.

Thanks

Brian.

Are you sure this command changed the permissions?? Are the permissions changed or the ownership of file/dirs changed??

Do you have the latest backup??

All the directories are now owned by www:other

Thanks

swverify will identify everything that is no longer the system default.

# swverify \*
Look at the /var/adm/sw/swagent.log for details. It will include permissions, owner and group problems in great detail.

Hi Brian,

Frankly I'm having a hard time believing that the usermod command did this. The *only* way to affect files with the usermod command is with the -d (home dir) & -m (move home dir) parameters.
It's more likely that a chown command followed after the usermod & it's the culprit.

My 2 cents,
Jeff

Beleive me!!!!! I tried it on other B2000 workstation and DISASTER AGAIN. It changes all ownerships to www:other. Just usermod -u 209 www. That is all. Any ideas??

Thanks

Hi Brian,

I believe you.
You haven't stated the OS, but if 11.0 look at PHCO_29380 - useradd/usermod cumulative:

http://www2.itrc.hp.com/service/patch/patchDetail.do?BC=patch.breadcrumb.main|patch.breadcrumb.search|&patchid=PHCO_29380&context=hpux:800:11:00

It definitively spells out that symptom.
Curiously I don't find that in the 11.11 patch.

HTH,
Jeff

Just wanted to confirm. This was a reported problem. The fix was originally released in a patch March 2003:
Patch Name: PHCO_28505
Patch Description: s700_800 11.00 user/group(add/mod/del)(1M) cumulative patch

And as Jeff correctly indicated, it is now supersede PHCO_29380
