[Solved] ssh works but scp does not

For quite sometime now, I was having this issue, that for the home system, I was able to connect to is using ssh but it never worked. Fnally after quite some debugging finally I found that the issue was with thebashrc. So, everytime I had to do a scp I would have to move/rename bashrc and do the reverse action after the scp was done.

faster bash operations on files with File Descriptors.

I was writing a bash script that would do some operations and read and write to file. Seems that that was pretty simple with

  <td>
    <div class="text codecolorer">
      while read line<br /> <br /> do<br /> <br /> done<file
    </div>
  </td>
</tr>

and then use redirection operations like “>” and “»” to write to file. Done with the script pretty fast. So far so good, when I went for real life tests, no one was interested in using it, why? Simple, it was simply taking too long. The file was reading about 10K lines and writing about 50 lines and was taking about more than 10 minutes.

Terminating a SSH session after starting background process.

This is too good. If you are planning to start a background process in the bash script in the background and continue in the script, you cannot do it until…….

You would need to close the stdout/stdin and stderr before you can terminate any ssh session automatically. Here’s some more light on this topic.

Easy ssh configuration with .ssh/config file

If you ssh to many hosts then you are aware of the pain that it takes to ssh with different username and hostname. There is an alias that you can creat with native ssh though. Here I will show you the same with an example.

  <td>
    <div class="text codecolorer">
      cat <<EOF >>~/.ssh/config<br /> Host <alias><br /> Username <user name><br /> Port <port number><br /> Hostname <hostname>
    </div>
  </td>
</tr>

You can optionally omit the parameters that you do not require explicitly. For example, if your port number is default then you can simply ignore the parameter.
