Can't telnet or ftp into Redhat 7.1 box

[TDub]

I just discovered the answer to a question that I posted a few weeks ago. I was unable to telnet or ftp into a Redhat 7.1 box after the OS install. I just realized that I selected the medium firewall option that does not allow remote access into any ports below 1023. Does anyone know how to disable a firewall on a Redhat box?

You could disable the firewall script from executing on system startup, it's probably started from a symbolic link in /etc/rc3.d or /etc/rc5.d.



alternatively you could flush the firewall rules using the following as root:



ipchains -F

ipchains -P input ACCEPT

ipchains -P output ACCEPT

ipchains -P forward ACCEPT

I've never seen the firewalling choices during 7.1's installation....but, I still haven't done the graphical install. however, it's most likely starting in one of your init scripts, so you might want to poke around in there looking for any references to ipchains. hmmmm, Red Hat uses a SysV-style init process, but I think it keeps the scripts in /etc/rc.d/init.d/, instead of the usual /etc/init.d/.....but I wouldn't suggest you rm anything in that directory, you can just remove the link in the /etc/rc.d/rc*.d directory to prevent it from being loaded....or if it's part of a larger script, just comment out the offending portions.


the odds are that won't let you connect, though...you're probably going to have to add an entry or two to your /etc/hosts.allow , in order to telnet or ftp in....ummm, could I suggest openssh and sftp?
