David, I tried to send you some firewall HOWTO info that really streamlined firewalling my Potato box. Unfortunately, I got a 'Returned mail: Service unavailable' notice from the bellsouth.net postmaster. I didn't send it to the list since I've posted it here before, so let me know if you'd like it and what addy to email it to, ok? montefin

Generally, running telnetd is frowned upon. That's not to say it's not secure, but it's easier to crack, and very easy for someone running a sniffer to grab your password, since telnet is not encrypted. Maybe Tera Term with the extra ssh modules can do it, or putty on a floppy, that way you can carry it around with you and access your box over a secure connection from any Windows box. Just some ideas that I'll try out when I start on my new job next friday. :-) Regards Morten -- UNIX, reach out and grep someone!
DSL and Debian questions Round 2
Hello everyone, Thanks for all the responses. I think I'm getting closer to understanding what's going on. So just a few more: 1. After installing an ethernet card and making sure the corresponding module gets loaded do I just runt the pppoe program and it'll do the configuring? Probably more to it than that huh? Do I need to worry about the external modem that comes with the service re: drivers and such? 2. The firewall issue. I've never set up a firewall. Is there a Debian package that will help with this? Any advice? I'm a little surprised that this is any more of a problem with DSL than with a normal dial up connection, anyone want to volunteer a little more info? How secure is the normal Debian installation? I have occasional need to telnet into my box from work, will this still be possible with a firewall installed? 3. The service I'm looking at claims 1.5 Mbps download and 256Kbps upload -- is this fairly normal? Again, I really appreciate all the responses to this and all the other questions I've had. Hopefully this'll be it until the modem gets here and I all of sudden can't install it ;-) David Bellows

Any advice? Go to http://freshmeat.net and do a search on firewall. I've heard good things about PMFirewall as far as ease of use goes. But, setting it up and getting a firewall to be secure and do everything you want to do isn't a trivial undertaking. I'm a little surprised that this is any more of a problem with DSL than with a normal dial up connection, anyone want to volunteer a little more info? DSL is going to give you a permanent, 24/7 connection to the internet. If you were a cracker what would you spend time on, a system that's connection is transitory, like a dialup PPP connection that could go away at any minute and have a completely different IP address the next time it shows up, or a box sitting on the net ready for your cracking convenience any time you want to take a stab at it? If you get tired of cracking tonight, it'll be there tomorrow, or next week, or next year for you to continue. How secure is the normal Debian installation? It's up to you. If you didn't run any network daemons it'd be pretty safe. Of course then you'd be limited to only outgoing connections. How much software are you going to install and run on your system? The more network software you install the less secure your system will be. If you just had a system with say sshd (SSH daemon) running you'd probably be pretty safe, but then start adding things like SMTP, rshd, telnetd, etc., and you're probably asking for trouble. And don't even start with NFS... I have occasional need to telnet into my box from work, will this still be possible with a firewall installed? Generally, running telnetd is frowned upon. That's not to say it's not secure, but it's easier to crack, and very easy for someone running a sniffer to grab your password, since telnet is not encrypted. 3. The service I'm looking at claims 1.5 Mbps download and 256Kbps upload -- is this fairly normal? Yeah, sounds pretty typical for a home ADSL installation. Many service providers offer more bandwidth for more money. Gary
