I am trying to copy a Cisco IOS image from a switch so I can push it to another switch.

Sounds like the type of application where I tend to use scp. Would that do the job? Or maybe I misunderstood your question.

I was able to copy the switch software to my desktop using PuTTY's SCP tool. openSSH in debian was not able to work due to non-supported crypto. I was able to get SSH working with the below commands in .ssh/config:

tmb@debian-hp:~$ cat ./.ssh/config

host 169.254.180.1
       KexAlgorithms +diffie-hellman-group1-sha1
       HostKeyAlgorithms +ssh-rsa
       Ciphers +aes128-cbc

I was able to transfer the software to the other switch successfully using TFTP. The switch that needed to be upgraded also did not support crypto. So I could not just SCP directly from one switch to the other. What should have been easy ended up taking two hours to complete. I also tried setting up a FTP server and I could not get FTP to work either. Anyway everything is working now.

Thanks for your help

needs ssh access on remote device for this to work

push a file from cwd to 169.254.180.65:

me@debian:~$ scp myfile.bin me@169.254.180.65:/home/me/myfile.bin

pull a file from 169.254.180.65 to cwd:

me@debian:~$ scp me@169.254.180.65:/home/me/myfile.bin myfile.bin
