...ror message like Received disconnect from 2001:db8::8077 port 999:2: Too many authentication failures Authentication failed. AFAIU the ssh-agent is to blame here, trying out all keys he has ever seen. This conflicts with MaxAuthTries 6, set by default on the peer. The solution seems to be to set IdentitiesOnly, e.g.: : : Host host.example.com 2001:db8::8077 IdentityFile ~/.ssh/id_ecdsa IdentitiesOnly yes Port 999 : : Shouldn't an explicit IdentityFile (as in the example) *imply* IdentitiesOnly? Every helpful comment is highly appreciated Harri

...report to Ubuntu [1] I was wondering that this issue seems to exist for so long and affect so many people [2][3][4][5][6][7][8]. It was also discussed within openssh in [9][10]. But in all of those cases all that was done was to suggest workarounds like "PubkeyAuthentication=no" or "IdentitiesOnly=yes", but IMHO those are all just exactly that - workarounds. Also there are many "related but not entirely the same" upstream bugs like [11][12], but it seems no one has yet discussed the approach we had in mind.

Hey everyone, I hope this isn't an old issue; I wasn't able to locate it in the archives. I have a number of scripts which make use of ssh -i and scp -i, where the target host has the specified key in its authorized_keys file with a command= override to do immediate processing of the received data. This works extremely well, as we are able to establish single-function, triggered-action

You can set IdentitiesOnly to apply to all hosts using ssh_config(5) Or you can be trickier in the configuration, but it is the IdentitiesOnly option which you need set to 'yes'. Put it and any other general rules at the end of the config file because the configration operates on a first-match basis. /Lars

...key will fail. If ssh is adding the new key to the end of the list it would be expected to fail. This limit is actually why I haven't added to the newer key to the agent also. Which leads to an idea: how about switching the "-i key" to the top of the list, instead of the end. > IdentitiesOnly Ok. The option "-o IdentitiesOnly=yes" is another solution. A problem with that, it's a bit cumbersome. You have to realize what the cause of the problem, so that adding the flag will fix it (why is ssh failing anyway?). And then check the exact syntax.

Hi, I run into a certain problem from time to time. 1. Configure and launch ssh-agent. 2. That's usually perfect. 3. Occasionally, connect to a different and less common remote server. Use ssh -i keyfile 4. ssh -i keyfile fails. Because ssh-agent doesn't know about that key. If you are specifying a key "-i key", then you are specifying a key, and clearly don't need to use

And then check the exact syntax. And write that, on the > command-line. It is another option though. Personally, I set IdentitiesOnly yes as the global default in ~/.ssh/config, and explicitly set the preferred key separately for groups of hosts. All my keys are under ~/.ssh/keys or ~/.ssh/sk so they don't get automatically picked up by the client when a host hasn't been defined yet. The client is only cumbersome if yo...
