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
