I use redhat linux 8 to connect 2 pcs using realtek ethernet cards. I tried to connect to each computer using the smbclient command but it juz won't work. An error message said that my connection is refused.
After using the 'ps aux | grep smb' command,the output was: ocy 1113 0.0 0.1 3536 628 pts/1 S 20:52 0:00 grep smb to test the smb.conf file. Does the output mean that my smb.conf is correct ?
I also used the ping 169.254.61.56 command and the output seems to indicate connectivity btwn the 2 pcs.
Does my refused connections mean that the firewall rules is too strict ? Another help reply from the net told me that my firewall level is too high.
Hence,I went to redhat desktop and opened the security level program under the systems settings menu.
The default security level is high. So I changed the security level to 'no firewall'. When i clicked the ok button, a msg ' Clicking the yes button will set the security level of the system and override any existing firewall configuration. Are you sure you want to do this?' I clicked yes and exited the prog. However, when i opened the security level program again, the security level is still high.....none of the changes I made are in place. I tried resetting the security level again and got the same mesage but still the security level is still high. I even tried the medium security level or customizing the high level to allow my eth0 card to be trusted but after exiting the prog and returning to it, the security level is always high with no customizations allowed.
I tried the redhat-config-securitylevel command but the same GUI program popped up and the same thing happened...the security level is always set to high no matter what changes i have made.
Do you know how to permanently change the firewall setting in redhat linux 8 ? And does the error message of refused connection mean that my firewall setting is too strict ? Please reply quickly if you can....thanks!! :wink:
