IPL with SI70819 upgraded OpenSSH disabling ssh-dss (DSA) public key algorithm.
Multiple production SFTP failing.
Unable to negotiate with xxx.xxx.xxx.xx port 22: no matching host key type found. Their offer: ssh-dss

Remote sites either need to upgrade
Or
Re-enable ssh-dss using the HostKeyAlgorithms configuration option:

ssh -oHostKeyAlgorithms=+ssh-dss user@legacyhost

or

in the configuration file

WRKLNK '/QOpenSys/QIBM/UserData/SC1/OpenSSH/etc/ssh_config'

and add these to entries to the ssh_config file.

Host somehost.example.org --> the host name you use to connect/ip address

HostKeyAlgorithms +ssh-dss

Anyone else having these issues?
Which work around have others used?

Thank You
