Subject: sshd: fatal: seteuid XXX : No such device or address
Date: Thu, 14 Mar 2019 11:39:00 -0000 [thread overview]
Message-ID: <011a01d4da5a$96247330$c26d5990$@giraudbtp.com> (raw)
Hello the list,
Thanks for all the work and effort put into this.
Since two days i cannot login anymore (password less) with ssh into my
server
Server is :
Microsoft Windows Server 2012 R2 Essentials / 6.3.9600 N/A version 9600
Cygwin was not up to date, but I have since updated it
CYGWIN_NT-6.3 [MACHINE NAME] 3.0.3(0.338/5/3) 2019-03-09 19:12 x86_64 Cygwin
I can login via password, it work and lets me in.
But if i tried with my keys, I get in the event viewer :
sshd: PID 3777: fatal: seteuid 1049076: No such device or address
I tried googling around, reinstalled multiple times sshd, the user and the
service with no luck so far.
I was working for several years now.
For now I have no clue, so i'm asking what did I do wrong ?
