Firewall-2.4 on Redhat Enterprise Linux 3.0
 
Hello All,

I am at my wit's end and need some help. I am running thje firewall-2.4 stroger script on Redhat 7.3 currently with no problem

(http://www.ecst.csuchico.edu/~dranch...l-2.4-stronger)

I just got a copy of redhat enterprise Linuux 3.0 and I am trying to replace the 7.3 box with rhel 3.0 .

Now here is the confusion, I cannot seem to run this same script on rhel 3.0. When i try running it manually from command line, I get the error:

[root@mybox root]# ./firewall.iptables
: bad interpreter: No such file or directory

When I place the script in the /etc/rc.d/init.d folder and create the appropriate links to the runlevels I want and boot up I get this error instead:

execvp: nosuch file or directory

As you can see from the script, it has the apropriate path to sh (i.e. #!/bin/sh).The bad Interprator seems to indicate it cannot find the sh or bash shell or something. Which is really weird because it works without a hitch on Redhat 7.3.

I have read various posts about this problem but could not find a conclusive fix for it . I found some hints that seem to indicate the execvp error is created by the /etc/rc.d/init.d/functions script but again no definite fix.

I am desperate and any help or suggestion will be greatly appreciated.

Kofi.

Prove where sh is...
which sh

Then make sure all the other programs are where they are in the script.
iptables would only be in /usr/local/sbin/ if it was built from sources rather than an rpm..

Do iptables-save to see how much of the script has run. It can give a clue on where it's dying..

Also do /etc/init.d/iptables clear to reset the firewall to open and ACCEPT
Make sure iptables isn't being run at any runlevel or it will clear your firewall..

execvp: No such file or directory
 
Thanks for your response. I did the which sh and it is in the right place. /bin/sh. The script doesnt even run, it fails. I posted this problem on bugzilla.redhat.com and I got this response back which does not make sense because as I mentioned the same script works on redhat 7.3 with no issues.

This is what I got from redhat:

Its almost like it can's run a shell script.

Help .. Please.....

check the file for crlf line endings, if the first line #!/bin/sh ends in crlf that is the error you will get
