Hi, Would you able to advise me to configure openssh running on Redhat linux ver7? Thanks. Best Regards _______________________ Joseph Keow
That depends on what you need help configuring. Have you tried: man sshd man sshd_config Note that, by default, ssh is blocked by the default firewall rules. You'll need to make sure it's enabled. If your only work with the firewall was whenconfiring it at install time, then you can redo the settings with the gui. Under KDE, the menu item appears to be: start -> System Settings -> secuity level. CAUTION: If your firewall settings have been customized (other than by the RdHat menus) then doing this may break your old settings. Before you go through with this, you may want to make a copy of your current settings in /etc/sysconfig/iptables mkdir /etc/sysconfig/RCS ci -l /etc/sysconfig/iptables does it nicely using RCS -- (I'd encourage anybody not using something better to get at least a base understanding of RCS. it does a very nice job of saving and comparing changes in various config files).

I have open all services on the firewall to make sure it can go thru. I hit this messages as:>ssh fwadmin at mgfwSSH Version OpenSSH_2.1.1, protocol versions 1.5/2.0.

Check wherever ssh is logging to (possibly /var/log/authlog) and try adding "sshd: 127.0.0.1" to /etc/hosts.allow (or wherever your tcpwrappers is compiled to look). Oh, and consider upgrading the the sshd, it's pretty old and possibly vulnerable. -- Darren Tucker (dtucker at zip.com.au) GPG key 8FF4FA69 / D9A3 86E9 7EEE AF4B B2D4 37C9 C982 80C7 8FF4 FA69 Good judgement comes with experience.
