hi... i was wondering if someone else had this problem runing
"./rc.firewall"
?

any help?

i already check the file with vim to see if there are any characters using ^M or something like but don't so i'm kind of scared here... i have to get this job done by today... it was working god i restarted the os and try to run the rcfirewall and got that error....

i also have the "sh" file under bin...

Can you post the contents of the file.

#!/bin/sh

It does seem a bit odd. Have you tried changing the shebang line to "#!/bin/bash"

yes

know i change everithing to the original file and i get
"bash: ./rc.firewall: Permission denied"

i don't know what to do

when i do the chmod u+x command i get now the same error

no such file...

What are the permissions on the file:
ls -l rc.firewall

-rwxr--r-- 1 root root 1138 Nov 25 14:46 rc.firewall

Something odd is going on if you can't even chmod another file.

Can you open up another terminal ok? If so, what happens if you create a simple bash script and run that?

i can run without problems "rc.local"

so i copy the star of this file and put it on the rcfirewall header... but nothing

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
modprobe ip_nat_ftp
modprobe ip_conntrack_ftp
modprobe iptable_nat
modprobe ip_conntrack

Looks like the file is a DOS file. Use dos2unix command.

Usage: dos2unix file.sh
