OK, with this additional information I can now reproduce it. Based on some quick experiments it seems to be triggered when sshd is built --with-ssh1 and the config does not *load* a Protocol 1 host key. Works: Protocol=1,2 + Hostkey not specified Protocol=1,2 + Hostkeys for both protocols specified. Doesn't work: Protocol=2 + Hostkey not specified. Protocol=1,2 + Hostkeys specified only for Protocol 2. Protocol=2 + Hostkeys specified for both protocols. -- Darren Tucker (dtucker at zip.com.au) GPG key 11EAA6FA / A86E 3E07 5B19 5880 E860 37F4 9357 ECEF 11EA A6FA (new) Good judgement comes with experience. Unfortunately, the experience usually comes from bad judgement. _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
