On both machines

Code:
# cat /etc/syslog.conf | grep auth
#       kern,user,mail,daemon, auth,... (see syslogd(AIX Commands Reference))
#

So I edited the syslog.conf and added as requested


on machine A : 10.1.1.105 = standby
after doing few ssh from the user oraprod & root

Code:
# cat /var/adm/authlog

Machine B: 10.1.1.120 = test1

Code:
# cat /var/adm/authlog

Dec 28 01:34:13 test1 sshd[340120]: warning: /etc/hosts.allow, line 1: missing ":" separator
Dec 28 01:34:16 test1 sshd[335952]: syslog: fopen on /dev/null failed, errno 2

Dec 28 01:34:53 test1 sshd[340122]: syslog: fopen on /dev/null failed, errno 2
#


Machine A /etc/hosts.allow had the ip address of Machine B which is
cat /etc/hosts.allow
10.1.1.120

and Machine B had the IP address of Machine A
cat /etc/hosts.allow
10.1.1.105

Then i removed the IP addresses from both files and the files are empty and did ssh from Machine A to Machine B and the log file is below

but when I do as a root the ssh log file will catch it
but when i do as oraprod
nothing appears in the log file

Code:
Dec 28 02:20:30 test1 sshd[336016]: Authentication refused: bad ownership or modes for file /.ssh/authorized_keys
Dec 28 02:20:30 test1 sshd[336016]: Authentication refused: bad ownership or modes for file /.ssh/authorized_keys
Dec 28 02:20:35 test1 sshd[336018]: Authentication refused: bad ownership or modes for file /.ssh/authorized_keys
Dec 28 02:20:35 test1 sshd[336018]: Authentication refused: bad ownership or modes for file /.ssh/authorized_keys
Dec 28 02:20:40 test1 sshd[364778]: Authentication refused: bad ownership or modes for file /.ssh/authorized_keys

I redited /etc/hosts.allow on both machines and added the following

$ cat /etc/hosts.allow
ALL:ALL

then log file

Code:
Machine A
