Re: 1.5.14: strange sshd error (openssh-3.9p1-2)

[Greg Kempe <thelonghotsummer at gmail dot com>]

Sorry, some missing information:

Windows XP sp2, openssl 0.9.7f, cygdll 1.5.14, user Greg is part of
the administrators group, the id_rsa* files are owned and readable by
Greg. CYGWIN environment var is "ntsec tty".

Thanks again

Greg
