Cannot connect to recent OpenBSD SSHD. about irssiconnectbot

[vext01]

For what it's worth, I can connect using the ssh binary from terminal emulator on my phone, but not using irssi connectbot. Seems like a connectbot issue.

I think this is related to this: http://www.openbsd.org/faq/current.html#20140603

Weak or broken hashes, ciphers and modes were removed from the
default sshd(8) configuration. Some clients do not support any of the
methods which are now available by default, so will not be able to connect
without changes. In those cases, the client should be updated or replaced.

I recommend switching to JuiceSSH in the meantime:

Sadly this replacement is not open source.

Seems to be already fixed in upstream ConnectBot. This fork however still relies exclusively on weak and broken algorithms and should be updated ASAP.

As of now, the following algorithms can be considered strong and secure:

KexAlgorithms [email protected],diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
Ciphers [email protected],[email protected],[email protected],aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc
MACs [email protected],[email protected],[email protected],[email protected],hmac-sha2-512,hmac-sha2-256,hmac-ripemd160,[email protected]

Unable to negotiate with xxxx port 48448: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

almost 6 years later, still no real improvement. Time to abandon this app.
