Internet security - cable modems ?
by Andrew Cartwright 26 Feb '01

26 Feb '01

Hi, I would appreciate your help once again, I am using RH 7.0 at the moment and have just configured my NIC (Netgear fa311) to enable my cable modem internet connection. RH 7.1(fisher) configures everything automatically IE NIC,DHCP and firewall. this is all very well but doesn't teach me a great deal about what is going on in the background. I intend to set up RH 7.0 with a firewall and any other security measures that are needed. I would very much appreciate any suggestions/help that anyone can offer to assist me setting up the required services. Things along the lines of :- Which services to disable (and how) Which firewall - ipchains or other package and tips on setting it up TIA

I think I'll let both sides howl each other out. ;-) The older hands who remember Laurie's earlier generosity to the group will know he's not the type to say such things for no reason. Those who don't care about IR35 can deal with them if they want to. The list policy on advertising remains "fuzzy" and it's generally a good idea to seek guidance *before* you post. -- MJR

Faxgetty, Mgetty and data calls - anyone?
by Barry Samuels 24 Feb '01

24 Feb '01

I've spent hours and hours trying to set up Hylafax/Faxgetty to auto detect fax/data calls and respond appropriately. I have had partial success in that I can now get it to distinguish between fax and data calls and accept the fax or start mgetty for a data call. Part of my original problem was that the default config.ttyS1 GettyArgs included -h as the first option which caused Mgetty to start and then immediately stop after printing a 'Usage' line in the log. I have, at least been able to correct that. My current config.ttyS1 gettyargs is: GettyArgs: "-D %l dx_%s" I have also tried "-r -s %s %l" together with many other combinations. If I dial in from another machine the call is answered as a data call and mgetty started but on the machine that I dialled in from I see a line of about two dozen characters, most of which appear to be '?', then the cursor returns to the beginning of the line, overwrites part of the existing line before dropping down one line, printing a few more characters then dropping down another line and displays 'NO CARRIER'. I never get to see a login prompt and these tests are costing me a fortune in telephone calls! It doesn't seem to make any difference whatever options I try the result is always as described above. The getty on the Hylafax machine is left running and has to be killed. The mgetty log shows: 02/23 09:52:33 yS1 mgetty: experimental test release 1.1.21-Jul24 02/23 09:52:33 yS1 check for lockfiles 02/23 09:52:33 yS1 huh?

The machine that I'm dialling in from is running Windows 95 although I have tried it from another Debian machine using Minicom with exactly the same results. I apologise in advance for that bit of important information that I have almost certainly forgotten to include. What am I doing wrong? Help would be very much appreciated. Barry Samuels

Check out Ghostscript/Ghostview - this will allow you to print almost any format to almost any printer. It will display these formats to screen as well. Most things the evile (sic) empire charge for have been free from GNU for twenty years or so!

As a matter of restraint I'd sit back and check what printing you REALLY need. If you print out a lot of things that you can't be bothered to read on screen - long alug mailings etc - you really dont want to be paying 4+ pence per page and then throwing away half the colour cartriges. The company I work for spends 90%+ of its printing costs on paper and ink that goes from printer to hand to bin. If its an attractive document e-mail it and let the recipient print it ,if its not an old dot matrix will almost certainly do and and old line printer is a revelation! But they dont beep when thay run low on ink which some people just CANT (sic) live with. But then thay dont print illegibly in yellow either.
