input_userauth_request() vs. stateful authmethods
The way things are now, input_userauth_request() calls the authmethod, and then does a bunch of checks, like the special case for root. If an authmethod requires a challenge-response conversation, these checks are skipped, unless they are duplicated by the authmethod. For example, in auth2-chall.c, some of the code is duplicated (logging, sending the reply), but the root special case is skipped.

Open SSH public key setup not working on windows 2012

Logfile encoding question
Hello. I've got a question about encoding in sshd's log files. When I try to log in with a "?" username, which is a cyrillic "h" (U+0445), I get this message in a logfile: input_userauth_request: invalid user \\321\\205 [preauth]. I am struggling to understand: is that hex, is that octal? It doesn't map to any encoding that I know of.

[OT?] Kerberos, PAM, NSS: if user does not exist, pam_krb5 try login?
A bit more then a curiosity. Mobing from Samba/NT to Samba/AD i'm now switching some 'one-purpose' (mostly containers) from libpam-ldaps to libpam-krb5. In these box normally i don't need user access, so i create 'manually' (eg, in /etc/passwd) only the admin users, and i add only the PAM layer to do external auth. Still i use ssh keys for direct root access, but as an

Non-root hostname auth problem
All: I have a problem connecting Openssh 3.0.2p1 on Solaris 8 using hostname authentication for non-root users. When I connect to the sshd from a second machine as root it works fine using HostbasedAuthentication, but it always fails with non-root users. I suspect that I am having a permissions problem somewhere, but I'll be damned if I can figure out where. Any and all help

With sshd running on an IRIX server, I connect with any other version/OS ssh, watch the connection establish, get right up to the point where the shell should spawn and sshd terminates. I have been unable to find any information online
