Permission denied?

I am trying to run a dyndns client (runDNS) on my fedora server, but it gives me a "Permission denied" error whenever I run it. It is a perplexing problem, especially since I am logged in as root, who should have all permissions...unless something is seriously messed up...
Anybody have any ideas?

[edit]I think this might be in the wrong forum...I feel like an idiot...someone can move it if that is necessary.[/edit]

Can you post us the EXACT error message? Thanks.

-bash: /bin/rundns: Permission denied

***Moved to Servers***

Can you post the output of this:

Code:

---

ls -al /bin/rundns

---

Thanks for moving this.

The output of that command (actually

Code:

---

ls -al /usr/bin/rundns

---

since rundns is in /usr/bin and not just /bin) is:

Code:

---

-rw-r--r--  1 root root 856467 Jan 30 00:03 /usr/bin/rundns"

---

Thanks for your help.

It's not executable, chmod +x it and try again.

more effective chmod arguments would be this:

Code:

---

chmod 0755 /usr/bin/rundns

---

that means:
0=do not set the SUID, GUID, or Sticky bits
7=owner can eXecute, Read, and Write the file
5=group can eXecute and Read
5=others can eXecute and Read

Thank you everyone for your help. I'm very new to Linux, so I'm still learning my way around it.

Yeah, but since it's already 644, +x will make it 755 ;)
