  • Copy a file over SSH without SCP

    I have come across multiple situations where I could only get to a server from a very restrictive bounce point which would not allow file transfers. I was able to uuencode a file, copy the output to a text file over putty, and then uudecode the file to transfer it. This works with any kind of file. Show Sample Output


    -4
    uuencode -m <filename> <filename>

  • test connection if ICMP is disabled

    Telnet will make a tcp connection to a remote ip/port to test connectivity. If it times out, it's not reaching the host (maybe the firewall is blocking it). If connection is refused, it's reaching the host, but either the service is not listening on that port, or it's locked. Show Sample Output


    -2
    telnet <ip> <port>
