SSH access no longer working for user `macro'

SSH access no longer working for user `macro'

[Maciej W. Rozycki]

Hi,

 I've had my `macro' account for years if not decades at `sourceware.org', 
`gcc.gnu.org', however it has stopped working sometime between last week 
and today.  I've had SSH protocol version 1 forced for these hosts since 
time immemorial for some reason I no longer remember, and now I get:

Protocol major versions differ: 1 vs. 2

when I try to connect, e.g. to pull from a repository.  Conversely if I 
remove the version 1 override from my setup, then my private key is 
refused for authentication, which is also why I had to downgrade my SSH 
client at my last hardware/OS upgrade to keep support for protocol version 
1 so as to be able to log into `sourceware.org', `gcc.gnu.org'.

 Please help.

  Maciej

Sourceware only supports protocol version 2.

Your key is an unsupported RSA1 key.

You need to regenerate a new RSA (not RSA1) key.

I can help you with this step, and help install your new
public key on sourceare.

Hi Carlos! :)

 Well, my key dates back to 2002 AFAICT, and presumably corresponds to 
what was supported back then at sourceware.  It also happens to be my only 
key that is RSA1 and I have older keys that are RSA2.

 I've got a new key pair generated now, how do I install my new public key 
then?

 Thanks,

I'm taking this off list and will work with Maciej to complete his account
setup.
