...making Linux just a little more fun!

Hi,
I have installed my ipsec tools in my linux-server. I am observing some issues while testing.
These are the steps, i done:
============================ https://ipsec-tools.sourceforge.net https://ipsec-tools.sourceforge.net for installation (tar file location) a. Copy the file *.tar.gz to your linux machine b. Untar the file tar xvzf *.tar.gz c. Then issue ./bootstrap d. Issue ./Configure e. Go to src directory. Setkey is installed f. Setkey is available in the /sbin directory. so i changed the name and Copy the setkey directory to /sbin. g. Then created set-key file. [root@linux scripts]$ cat set-key #!/sbin/setkey -f flush; spdflush; add 10.0.0.1 11.0.0.2 ah 500 -A hmac-md5 0xabcd1234abcd1234abcd1234abcd1234; add 11.0.0.2 10.0.0.1 ah 600 -A hmac-md5 0xabcd1234abcd1234abcd1234abcd1234; #add 10.0.0.1 11.0.0.2 ah 500 -A hmac-sha1 0xabcd1234abcd1234abcd1234abcd1234abcd1234; #add 11.0.0.2 10.0.0.1 ah 600 -A hmac-sha1 0xabcd1234abcd1234abcd1234abcd1234abcd1234; add 10.0.0.1 11.0.0.2 esp 500 -E 3des-cbc 0x1234abcd1234abcd1234abcd1234abcd1234abcd1234abcd -A hmac-md5 0x1234abcd1234abcd1234abcd1234abcd; add 11.0.0.2 10.0.0.1 esp 600 -E 3des-cbc 0x1234abcd1234abcd1234abcd1234abcd1234abcd1234abcd -A hmac-md5 0x1234abcd1234abcd1234abcd1234abcd; spdadd 10.0.0.1/32[any] 11.0.0.2/32[any] any -P out ipsec ah/transport//require esp/transport//require; spdadd 11.0.0.2/32[any] 10.0.0.1/32[any] any -P in ipsec ah/transport//require esp/transport//require; spdadd 10.0.0.1/32[any] 11.0.0.2/32[any] any -P out ipsec ah/tunnel/10.0.0.1-11.0.0.2/require; spdadd 11.0.0.2/32[any] 10.0.0.1/32[any] any -P in ipsec ah/tunnel/11.0.0.2-10.0.0.1/require; h.

That "#!/sbin/setkey -f" could be the source of the problem. What does ls -l /sbin/setkey tell you?

If you read a bit further, Kathik says
h. The issue is, The file has full permission, but it says permission denied. -rwxrwxrwx 1 root root 1054 Feb 26 04:44 set-key
That looks executable to me, unless I'm more confused than usual.

I'm pretty sure that's the problem. A first line starting with #! is known as a sha-bang. It tells Linux that the script should be interpreted by the command given, e.g. "#!/bin/bash" requires the bash shell.
In this case you are telling Linux that it should run "/sbin/setkey -f" to interpret the set-key script. As /sbin/setkey is not an executable file it will fail, as you have observed.

Hi,
Thanks for your quick reply, Then can i use "#!/bin/setkey" in first line of the set-key file.

Possibly.
If /bin/setkey is a binary capable of interpreting the set-key file correctly, than that should work.

What do you get from "ls -l /bin/setkey"?

The output of this shows that "setkey" is a directory. What you need to show is a listing of the output of
ls -l /bin/setkey
It is /sbin/setkey which is invoked by the script

Finally, from your command-line:
> [root@linux scripts]$ ./set-key
... I deduce that you are trying to execute this script as an ordinary user (not super-user). Since /bin/setkey changes some network parameters it is extremely unlikely that anyone other than the super user is allowed to use this command in the way that you are using it.

OK, that proves it.
Your problem is that you've replaced the /bin/setkey program with a directory. Directories are not "executable", and cannot be the target of a hash-bang, so your script, which starts with
#!/bin/setkey -fcannot execute the /bin/setkey program (because it doesn't exist), and fails on a "permission error".
I have no easy way to fix this. The only way is to back out your changes: remove the /bin/setkey directory and put back the /bin/setkey program. Then, see what else has been trashed as part of this install, and fix it as well.

It seems /bin/setkey is a directory, not an executable, so there's little point in trying to use /bin/setkey in the sha-bang. You need to work out where the setkey executable is and use that path. "locate setkey" might find some likely candidates if you have locate set up?
I would also consider moving the setkey directory to someplace other than /bin. It's intended to hold binaries, not directories. I would be inclined to put it under /usr/local/src or in a suitable user's home directory.

Hello
Oops many mistakes in this one!

In fact you have given us the output of "ls -l setkey" from the /bin directory so this is the same as "ls -l /bin/setkey". This proves that /bin/setkey is a directory.
Directories are not commands to be run.

That was also a mistake on my part. I should have said that it is /bin/setkey which is invoked by the script. Since that is a directory it cannot be invoked as a command and hence the "permission denied" message.

That's obviously a directory as well. In fact it looks like the same directory? Just moving the directory around won't help.
Is there a /usr/local/bin/setkey? If not and locate isn't working, you could use "find / -name setkey -executable -print" to find the executable.
I think you also need to take some time to learn to recognise the differences between files and directories.
