Hi all,
Seeing some strange behaviour on 3 different 7.3 servers. Each with fully
qualified hostnames and their sshd_configs are exactly identical.
The strangeness is as follows - I can connect from client machines simply
using rsa authentication on 2 of the servers and ::: then can't connect
using the same accounts between the 2 servers.
So I will illustrate this to make it easier to understand:
1. client machine ::: x.x.y.100
2. Server1 ::: z.y.x.209
3. Server2 ::: y.z.x.25
4. Server3 ::: z.y.x.210
Now I try to connect with (client machine)user@(protected) to
(Server1)user@(protected) >>> connection works fine
Then I try to connect with (client machine)user@(protected) to
(Server2)user@(protected) >>> connection works fine
Then I try to connect from (Server1)user@(protected) to (Server2)user@(protected)
and every thing fails.
Here is the sshd_config:
Subsystem sftp /usr/libexec/openssh/sftp-server
IgnoreRhosts yes
RhostsRSAAuthentication no
RhostsAuthentication no
IgnoreUserKnownHosts yes
PrintMotd yes
StrictModes yes
RSAAuthentication yes
PermitRootLogin no
PermitEmptyPasswords yes
PasswordAuthentication yes
ReverseMappingCheck no
GatewayPorts no
AllowTcpForwarding yes
KeepAlive yes
Protocol 1,2
LogLevel INFO
__ ____ ____ ____ ____ ____ _____
Here is the logged info on what transpires:
Oct 28 12:25:12 server2 sshd(pam_unix)[11031]: authentication failure;
logname= uid=0 euid=0 tty=NODEVssh ruser= rhost=server1.XXX.XXX user=user
Oct 28 12:25:14 server2 sshd[11031]: Failed challenge-response for user from
66.103.144.209 port 32855
Oct 28 12:25:14 server2 sshd[11031]: Connection closed by X.X.X.209
Thanks for any and all suggestions, help!!!
