OB II 4.0 returns invalid user/passwd

[lastgreatone]

Anyone have any luck adding a Linux 7.0 workstation as a client to OB II 4.0 Cell Mgr? the linux box can ping the cell mgr, & remote access is enabled, any clues?

Hello,

What do you mean by Linux 7.0 ? RedHat or SuSE ?

If you are using RedHat, you may know that "inetd" has been replaced by xinetd. Therefore, you need to create an entry for OmniBack in the related configuration directory as follows (file /etc/xinetd.d/omni) :

service omni
{
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/omni/bin/inet
server_args = inet -log /usr/omni/log/inet.log
disable = no
}

Of course, xinetd must be restarted after any change (/etc/init.d/xinetd restart).


Another clue : make sure that remote execution is enabled during the remote installation (may be rsh or rexec, but I don't remember which one runs). To do so, install the right software using Linux install CDs, then enable the service in /etc/xinetd.d and restart xinetd. Don't forget to temporarily rename /etc/pam.d/rexec or /etc/pam.d/rsh files accordingly.

Last thing : disable the securetty feature during the remote installation (rename /etc/securetty).

Good luck.

P.S. Don't forget to rate this answer (from 1 to 10).

I mean RedHat 7.0.

Well I tried all you suggested to no avail. I even added .rhosts, no luck.

I read somewhere that HP officially provides the support of Linux 7.1 Client on OBII4.0, could the version be my problem?

I don't think so
You user root don??t have permission to use the telnet.
See the host.allow and host.any
See /etc/securetty comment the line "telnet" or tty.
Verify /etc/pam.d/telnet

[castro_2]

You have rexec in the host?

What do you mean by rexec in the host?

BTW I have followed all the recommended steps and also consulted DOC: OV-EN004289 and still I get Invalid username and/or incorrect password.

I removed /etc/hosts.allow and hosts.deny should I have left them there and configure the files accordingly?

Hello Franckie,

Since 3.10, all OmniBack versions are correctly remotely installed on Linux clients.

Just check ALL these before proceeding the installation.

1. Make sure /etc/securetty mechanism is deactivated (rename /etc/securetty).

2. Make sure remote exec is enabled.
To do so, install rexec package, and configure it as follows :

-> /etc/xinetd.d/rexec and /etc/xinetd.d/rsh should look like this (particularly, pay attention to "disable = no" and "server_args = -h") :

service exec
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rexecd
server_args = -h
disable = no
}

service shell
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rshd
server_args = -L -h
disable = no
}

Of course, you have to re-start xinetd by typing /etc/rc.d/init.d/xinetd restart.

Then, you can type "netstat -a | grep LISTEN" to check if the host is listening on sockets "shell" and "exec".


-> both /etc/pam.d/rexec and /etc/pam.d/rsh should look like this :
auth required /lib/security/pam_nologin.so
auth required /lib/security/pam_securetty.so
auth required /lib/security/pam_env.so
auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth
session required /lib/security/pam_stack.so service=system-auth



Of course after the installation, you can restore all these security features.

Good luck.

Ok, part of the networking is resolved, but now from the cell mgr, after accepting username & password it remains in a pending state:
Starting installation.....
Getting list of clients for installation...
Connecting to client....
checking for response from system....
And it's still in a pending state.
Is this now a cell mgr problem, or does something else need to be done from the linux box? telnet works to and from linux.
