Error when connecting to older ExtremeXOS switch

[cchance27]

I've enabled all the deprecated features, but when i use the following connection

        .username(values[4])
        .password(values[5])
        .add_pubkey_algorithms(algorithm::PubKey::SshRsa)
        .add_kex_algorithms(algorithm::Kex::DiffieHellmanGroup1Sha1)
        .add_mac_algortihms(algorithm::Mac::HmacSha1)
        .connect(format!("{}:22", values[3]))
        .expect("Unable to connect to SSH")
        .run_local();

I get the following, which is odd it seems like the server has no response? I can connect to it with old versions of putty.

I think this might be because of an outdated pubkey algorithm that isn't supported "ssh-dss"?

ERROR ssh::config::algorithm: err_msg: "Key_agreement: the signature algorithm fails to match, algorithms supported by the server: ,algorithms supported by the client: rsa-sha2-512,rsa-sha2-256,ssh-rsa"

Hi,

ssh-dss is not listed as a supported algorithm currently.
You can bump the log level to "INFO", showing the original cypher list that the server returns.
The error message only shows the after-modifying cypher list, which by design can only list the algorithms we supported.

BRs.
