How to prove that I was able to do secure copy
 
Hi Guys,

I have a Unix Server where I was able to do secure copy (scp)but now I am able to. I want to prove it is there any log file I can have a look at which states success and / or says I did scp?

Please help me here.

Thank you

If it fails, it'll tell you. You can also check the exit code '$?'; should be 0 (zero) for success.
If this is in a script, make sure you check the exit code and log both stdout and stderr eg
Code:
# call script
./myscript.sh >myscript.log 2>&1

# basic code for script
#!/bin/bash
scp myfile user@host:/dir/myfile
if [[ $? -ne 0 ]]
then
    echo "scp failed with $?"
fi
The error msgs will appear in the logfile.

I am not talking about scripting point of view but auditing point of view

I did ran scp sometime back is there anywhere store is system log about command a user performs I believe there must be.

dmesg?

In your first question, you wanted to know if the command ran to success or not. In your next, you wanted to know if there is a history of commands a user perform. Which is it?

As root, you can view the history of the user(s)

Or a better way, you could do process accounting. It will give you a audit of your system and track commands executed by users. This article will explain it better http://www.cyberciti.biz/tips/howto-...ccounting.html

The normal service logs (normally /var/log/messages) would have information about the login.
