Cannot connect to old systems in SSH

[syntesys]

Hello all,

I'm configuring in a custom template a new item that executes an ssh agent to get the result of a command. I'm using a public key RSA 2048 SHA256, but in connection with old systems I receive the error

Public key try failed: The key algorithm 'ssh-rsa' is not allowed to be used by PUBLICKEY_ACCEPTED_TYPES configuration option

Note that using that key from bash, everything works good.

How can I resolve this?

I'm using a Debian 12 system with zabbix server 6.4.7 and the other system has a Raspbian jessie.

Thank you.

You say from command line it works, you mean when using user zabbix? You can control ssh client setting in the $HOME/.ssh/config file. Perhaps you need to set up a home directory for user zabbix and add this config file where you can control algorithms and other things.

could you solve this issue?

If yes, what was the solution?

I'm facing with the same problem. Thanks!
