Try to disable Firewall for testing purpose but failing
I am trying to change my firewall status of my 2 redhat 8.0 box from high to medium as I want to run pcxware from my win2k PC. But whenever I am trying to do its showing done but not working. I faced same problem for ftp and I did it manually. But I don't know which file to be edited to override default settings. I tried with service iptables stop. tried redhat-config-securitylevel as well as setup command. openssh is running in the boxes.
Thanks in advance

Re: Try to disable Firewall for testing purpose but failing
# service iptables stop
will flush your iptables rules. verify with this:
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
If you see this output, then iptables firewall is disabled. So the problem should be elsewhere...

Re: Try to disable Firewall for testing purpose but failing
I suspect that the reason things are not working after that command are that you need the firewall up for your testing.
So, perhaps post the configuration and the details of what you are trying to do and someone can help.
The commands in the prior post are exactly what were required to answer your question as written.
for open ssh testing try ssh -v to get some idea where the problem is happening.

Re: Try to disable Firewall for testing purpose but failing
Actually I am trying to manage my redhat linux 8.0 boxes remotely with pc-xware. I can manage my sun boxes. But its not allowing me for linux boxes. It is not allowing to ftp/telnet.I suspect that openssh may be the reason behind it. And after editing vsftp file I can ftp it. with Putty everything OK except telnet. But I can ssh this server. the output of scanssh is
192.168.70.231 SSH-1.99-OpenSSH_3.4p1
output of ssh -X -v 192.168.70.231 is
