Execution permissions by disk? (hopefully a stupid problem)

snafle · 2008-08-06 20:24:57

I've installed two new programs recently, srcds and the dmd d compiler. The dmd d compiler functioned perfectly when I first installed it, then I rebooted the machine, then I installed srcds.

Whenever I try to run dmd I get the error:

bash: /home/tom/Programs/dmd/bin/dmd: Permission denied

and whenever I try to run the srcds I first get:

bash: ./srcds_run: /bin/sh: bad interpreter: Permission denied

after which, I explicitly tell it to run with sh, at which point it tells me

'./srcds_i486' not executable, exiting

I'm quite confused as to why these programs are failing- all the permissions are 777, so should be free for all for everyone, yet no dice.
All my other programs work, however these are on a different partition (the ones I've having problems with are on my big Raid5 LVM array).

I have run several things on this disc before. The only change I can think of was moving my home folder to the big disc and symlinking back into the directory structure- this should not make a difference? (I didn't think). My FSTAB for that disc is rw,nosuid,dev,sexe,auto,user,async.

If anyone can shed some light, I'd be most appreciative.

Try chown

May we get a ls -l of these files? (and perhaps an id)

snafle · 2008-08-07 17:27:36

uid=1002(tom) gid=100(users) groups=6(disk),10(wheel),93(optical),100(users)

is the response from ID

and ls -l of my dmd folder is:

-rwxrwxrwx 1 tom users   85776 Aug  8  1996 dm.dll

As you can see, I own then, and they are all executable by everything. I'm outta my deapth.

Well.. do all other executables shell scripts execute? And yeah, _do_not_ keep a 777 permission... 755 is good enough for most

I can't execute anything on the LVM.

xvalentinex · 2008-08-09 22:09:10

Try putting the mount option ' exec ' in your /etc/fstab then remount your partition or reboot.

If it already has a ' noexec ' mount option, remove it.

It already does, I must have mistyped when I transposed it into here. The bit that says "sexe" is actually exec.

My FSTAB for that disc

rw,nosuid,dev,exec,auto,user,async

Weirdly thing is on my main disc (which is only different in that it isn't LVM- it's still a partition on the RAID 5 array), dmd works no worried. It's got to be something to do with the disc.

user implies 'noexec', so move exec after 'user'
