Description Yannick Bergeron 2011-10-21 23:35:30 AEDT

I've compiled and using OpenSSH 5.9p1 on AIX 6.1 TL6 SP4 / SP5
I've compiled it using this configure command:
./configure --prefix=/usr/local/openssh-5.9p1 --sysconfdir=/etc/ssh --without-shadow --with-ssl-dir=/usr/local/openssl --with-zlib=/usr/local/zlib

I've set some Public Key Authentication between a few systems.
My /var/adm/wtmp has started to increase in size but I can't see any entry being added when I try to display the content using those two commands:
last
who /var/adm/wtmp

But I'm guessing it's coming from OpenSSH because of this command:
strings /var/adm/wtmp |tail -n 20
openssh

N¡f(
openssh
N¡f-
openssh
N¡f-
openssh
N¡f2
openssh
N¡f7
openssh
N¡f<
openssh
N¡fA

Need to figure what is being added in /var/adm/wtmp, if it's normal and why it's not possible to display it with the regular commands such as "last" and "who /var/adm/wtmp"


Best regards,
