Beardo,


What are the permission on the file?

ll /proc/sys/net/ipv4/tcp_fin_timeout


Kind regards,


Jan Gerrit Kootstra

Woops.. forgot to mention that. My brain isn't working 100% today.
Anyway, the file's permissions are read only (-r--r--r--) but root
also does not seem to be able to change the permissions.

Entries in the /proc file system are not implemented as are normal files.
Not being files, they really don't have alterable permissions. A /proc
entry with 0444 permissions probably doesn't even have a write method
implemented.

HTH

Here's the problem though. I've been told through several resources
to change this file using

echo 30 >/proc/sys/net/ipv4/tcp_fin_timeout

And, I was able to do this on another fedora machine (I believe,
however, that machine was FC3)

Is there possibly some other configuration which might be blocking me
from doing this?

On my RHEL5 I see -rw-r--r-- as permissions

My RHEL4 ES perms for this file are -rw-r--r-- too.
