I am unable to make the sshd initiate a SSH2 rekey. Is this
supported ? I always thought that the KeyRegenerationInterval option
would work for both Ssh1 and Ssh2 but seems not to be the case. I am
trying to test some scenarios and am setting the value to be a small
interval like 1 minute or 5 minute and don't see any evidence of the
rekey happening even in the debug mode. Is there some other option to
Thanks in advance,

Re: Openssh server SSH2 rekey?
KeyRegenerationInterval is how often the SSHv1 ephemeral server key is
regenerated. It has no effect on SSHv2.
There's no option to force it on the server side. You can force it on the
client side with the RekeyLimit option, although that takes a byte count
not a time interval. You can also initiate a rekey using the "~R"
escape sequence on the client.
