I have 0 visible services, but I still don't want people doing port scans. Why pose a target when I don't have to. There is no reason why anybody should be pinging my house. Therefore, I don't let them. Why would I enable anything to let people see me? Stardard security practice: Only allow what is *needed*, and I don't *need* anybody pinging me. If I do, I'll turn it on.

Two situations: 1) You have no other internet-visible services: * What's the harm in allowing icmp echo? Who cares, unless there happens to be some vulnerable ICMP code in the kernel. I suppose that's a risk I'd be willing to take. :) 2) You have other internet-visible services: * A port scan will reveal you, regardless of ICMP responses. -- Josh Huber _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

Verizon DSL on SuSE
by avedis＠rcn.com 09 Apr '04

09 Apr '04

I got set up yesterday with Verizon DSL. I had to boot into windows to do the account activation, and their tech support walked me through it. Once the connection was up, I added a hub and a second computer (with XP - it's not mine, I swear) opened a browser and began surfing. Setting up DSL on SuSE 8.2 was pretty easy, considering I don't really know what I'm doing. Yast setup for a network card and dsl went smoothly. I only had to make one file edit, to designate eth0 in pppoe.conf, rebooted the computer and then could surf, with download speeds up to 1.7M/s. I even got my firewall working with the new connection, but two things seems to have changed. SuSEfirewall2 was set not to accept pings, and it looks like it's still set that way, but Gibson Research's port scanning utility can ping me. The other thing is that before, I had to manually enter commands (iptables) to drop packets to port 119 to put it into "stealth" mode. Now, I don't have to do that, as it already appears stealthed. Can anyone explain either of these phenomena? Greg

The firewall config file gives three choices - # Allow (or don't) ICMP echo pings on either the firewall or the dmz from # the internet? The internet option is for allowing the DMZ and the internal # network to ping the internet. FW_ALLOW_PING_FW="no" FW_ALLOW_PING_DMZ="no" FW_ALLOW_PING_EXT="no" I understand that the first two determine whether the firewall or the dmz respond to pings from the internet, but I'm not sure what the third option does. I am able to ping out to the internet, even though it's set to 'no', so I don't understand the last comment. > As for port 119, this appears to be the NNTP (net news) port -- why > would you be running a news server I'm not sure :) > Woops.

I generally find that linux irc channels fall into two categories. 1. Neophytes + Zealots (of windows and linux) duking it out online 2. Elitists discussing highly esoteric topics such as altering disk timing performance via hot kernel patches to /proc/kmem I'll take category 2 any day, generally through lurking I'll learn something.

Easier > might be just that (easy), but it sometimes means making the wrong > choice. For our poor little IRC channel, it was particularly bad. This kid had joined the LUG list, and offered to do all kinds of web development etc. with the hopes he'd get some free advertising for his "big business venture." No problem there, but he proceeded to rant on-list about wanting to use ASP etc., arguing against open-source content management tools as "boring." That carried over to the IRC channel, and he'd essentially scare off any potential Linux converts with his lousy attitude. > If a person wants to favor an operating system simply because it's > "easy", then that person deserves all the resulting heartache s/he > gets. often, the person looking for "easy" will think "ease of use" > instead of "ease to get going without immediate worry"... There was a great post a few years back (forgot which list) comparing web development using front page to the (original, good) Matrix movie precept. It got into the "warm, wet, comfortable goo" of FP, and how long and painful it was extricating himself and his code. Although it fit apple better in years previous, I think "Freedom From Choice" is what a lot of people want (with apologies to Devo). > If that > became a major concern instead, I think we would see a decided shift > towards unix variants.

You usually have to just find all the files and delete them. When you install stuff by compiling tar.gz yourself, there is usually no package management for easy uninstallation. Netscape probably installed to /usr/local/netscape* or something like that.

Dan Crooks ------------------------------- Brian, I am running Mandrake 9.2 and Win2K on a Dell Dimension in dual boot mode. Have used Win2K on a Comcast cable connection for 5 months. Comcast installer told me that they assumed I would be connecting with Windoze and Internet Explorer, which I did. But... I have since installed Mandrake 9.2. Installation was effortless and most importantly for this discussion, Mandrake found and connected with the cable modem on the LAN with no problem. I now use 9.2 and Galeon or Mozilla to surf the web. I share the LAN connection, without incident or effort, with my wife's XP Pro machine.
