I can't seem to play any games and I'm stumped.

I'm in the games group and directory permissions appear to be correct, but I can't access /usr/games/bin as my user at all.
Code:
dzmijewski@emachine ~ $ groups dzmijewski
wheel audio cdrom video usb users portage games dzmijewski

dzmijewski@emachine ~ $ /usr/games/bin/etr
bash: /usr/games/bin/etr: Permission denied

dzmijewski@emachine ~ $ ls -l /usr/games/bin
ls: cannot access /usr/games/bin: Permission denied

emachine dzmijewski # ls -l /usr/games/
total 4
drwxr-x--- 2 root games 4096 Feb 16 14:26 bin


emachine dzmijewski # ls -l /usr/games/bin/
total 564
-rwxr-x--- 1 root games 557216 Feb 16 14:26 etr
-rwxr-x--- 1 root games   1379 Feb 16 14:15 nethack
-rwxr-x--- 1 root games  10248 Feb 16 14:15 recover-nethack
What am I missing?

That doesn't seem like you are using ACL's. So I guess we can discard that.

I am not familiar with SELinux though, so if you are using it, you should check your policies or whatever they are called. If you don't know what SELinux is then probably you shouldn't worry about this.

Failing that, I would advice you to run fsck on that fs from a livecd. Sometimes, subtle fs corruption can cause this kind of weirdness. Anyway, what does the output of "stat" over the same files say?

I can't wrap my head around SELinux so I don't use it. I'll dig up my liveCD in a bit and try fsck. Here's output of stat for one of the files:
Code:
emachine dzmijewski # stat /usr/games/bin/etr
  File: ‘/usr/games/bin/etr’
  Size: 557216       Blocks: 1096       IO Block: 4096   regular file

what about the permissions of /usr/games

you have shown /usr/games/bin have r-x for group:games, but if a user cannot enter the /usr/games directory.

I would suspect either filesystem corruption or ACL - try:

Code:
getfacl /usr/games/bin


Recreate the dir, starting with:

Code:
mv /usr/games/{bin,badbin}

I checked SMART and ran both mhdd and fsck; everything checked out fine. Then I tried your suggestion to mv the dir and reemerged the game, and now it works. Thanks everyone for your help
