What needs to be activated so that I or others can telnet/access my box? I remember something about selecting ftp/telnet and firewalls at the time of installation..I have a router setup so when I do a ifconfig, it's connected to the internet via broadband and the router with the addy of 192...etc, but when I try to access the computer from another it won't connect. Is the router causing the problem?
Okay, thanks for the input all!
- For some reason my redhat 8.0 has lokkit, which i ran, but after selecting telnet and even no firewall, the menu reverts back to high security status...in other words its not saving my changes for some reason. With that said, I can telnet out, but can't telnet my local address, so the firewall needs to be fixed..i tried a couple of your suggetions..the -chkconfig telnet on- gave me...error reading information on service telnet: No such file or directory..
Opening /etc/xinetd.d i found no file named telnet either..as for /etc/services i did find telnet 23/tcp
I spoke too soon . It seemed I could telnet my box from my box and from a computer on the same network, but when trying to telnet from out of town or another comp etc it didnt work. I changed all the settings to allow incoming telnets. I did notice that when I changed the security level of the firewall to medium and customized to allow telnet, I clicked okay, but tried again with no luck. I checked the security lvl yet again, and for some reason it reverted back to high security firewall with nothing checked including telnet. Is there a way to permanently change this? I've tried in gnome and lokkit both and both revert back to previous settings..
Okay, I neglected to mention that we have a wireless router and my linux box is going through that. That is probably my problem, although I did not have telnet set up in the first place so thanks for helping get that up. So..i have a network address i guess. How can I set that up so i can access from a comp off the network?
Depending on your router you will need to sets its configuration to allow telnet traffic through to your linux pc. For Linksys routers this requires a static IP for the PC. Setup port forwarding for whatever port and IP you are using.
Assuming you have a dynamic IP you can use one of the many free dynamic ip servers like www.noip.com. A client program on your PC will update the server with your IP address and assigns a hostname (of your choice) to it. Now the rest of the world can access your PC.
