Lost SSH key

Hi everyone! Sorry to bother, but my old hard drive died and I lost my
SSH keys. I'm attaching a newly-generated public key; my account is
martingalvan@sourceware.org.

Again, thanks and sorry for the inconvenience.

Thanks a lot, however I still get a "Permission denied (publickey)"
error when trying the 'alive' command. I'm positive that my public key
matches the private one I'm holding, since the output of ssh-keygen -y
-f ~/.ssh/id_rsa matches the public key.

I noticed the public key file I attached previously had my login@host
at the end. I'm re-attaching the public key without those, maybe
that's causing the problem?

That is unlikely to make any difference, but I applied it.

What does ssh -v show?

Another one from the peanut gallery: it's not as simple as a
missing "chmod go-r ~martingalvan/.ssh/authorized_keys" on
sourceware, after appending the new key?

(Non-ancient sshd doesn't like world-readable public keys, even
though that information is supposedly safe-to-share.)

I don't think so.  Most, perhaps all, of the authorized_keys files on
sourceware are world-readable.

That looks weird; those two files should have apprx. the same
timestamp.  Did you generate -two- sets of keys recently, or some
other way intermix public & private keys?

Good point. Both files were generated at the same time; what happened
is that I later removed the user@host at the end of id_rsa.pub just in
case that was causing the issue.

Good God, that was it. Sorry for this whole mess, I completely forgot
to put my username before sourceware.org.

FWIW I was following this, which may also be wrong:
https://www.sourceware.org/sourceware/accountinfo.html

Thanks a lot for the patience guys.

Hello,

I have lost my old SSH key to access gcc.gnu.org. Back in 2017 I 
registered using rdapp@linux.vnet.ibm.com. This e-mail address is still 
valid (even though I would like to update it to the one I'm using now).

Would you kindly replace my public key with the one I attached? Thank you.

In case you will want to verify that I'm the person I claim to be please 
refer to krebbel@linux.ibm.com.

Regards
  Robin

Lost SSH key

I'm trying to re-establish my read-write access to GCC, but have lost my
SSH key, probably switching between several different systems over the last
few years. How can I reset the key for my account?

Thanks,

Andrew Sutton

Andrew,

Has anyone worked with you on this to resolve the issue yet?

If not then I can help. Please email me privately and I can set this up again.

Greetings,

I have an account emsr@gcc.gnu.org.  I have completely lost my ssh keys 
so I can't get updatekey to work.

Could someone please set my key up?  Here is a new public key attached.

Thank you very much,

Updated.  Keep a copy of this one.
