[vox-tech] Deleting a PGP keyring
To answer my own question, there's no special procedure. If you're sure you want to blow the whole keyring away, go to ~$HOME/.pgp and rm everything. --nicole twn *** "Say you decide to call it quits after the first exam.

You're absolutely right as usual, Jeff; stepping through assembly is proving massively helpful. (Why didn't I think of that?)

The latter sounds an awful lot like > header problems. My experience is this: the kernel panics (complete with "aiee, killed interrupt handler" message) before gdb has a chance to print out the first line of the glibc function socket(). I interpret this to mean that the kernel panics before control is transferred. Is this view correct? Based on your advice and the Linus post you linked to, I guess I have a new question for you, Jeff: What, exactly, are the consequences of compiling glibc against the wrong kernel headers? Could it be causing a kernel panic? And how can I tell which kernel headers glibc was compiled against?

[vox-tech] glibc and socket()
Hi guys I'm trying to track down a kernel bug. I've compiled my programs and the kernel with -g, and I'm stepping through the executable with gdb. A call to sockaddr_check() goes through OK, but a subsequent call to socket() triggers a kernel panic. Control never even gets to the first line of socket(). Breakpoint 1, initialize_listen_socket (saP=0xbfffea78) at libhttpd.c:384 384 if ( ! sockaddr_check( saP ) ) (gdb) n 390 listen_fd = socket( saP->sa.sa_family, SOCK_STREAM, 0 ); (gdb) s At this point, the system goes supine. According to http://www.skyfree.org/linux/kernel_network/socket.html , socket() is actually a glibc function; it sets things [1] up and then calls the system call sys_socketcall(). But I don't know where the kernel panic is triggered, and I also don't know how to recompile glibc or even if that would be a useful course of action. Anyone have any ideas? I've even tried compiling the target binary with -static; still no information on time/place of death. Thanks --nicole twn [1] I am not 100% sure WHAT things, though. *** "Can anything stop The Blob?!?"--old programming textbook Visit www.nicolopolis.com ... digital nonsense for a weary world. ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

I feel like saying, as a preface to all of this, that you have some learning ahead of you. Don't panic--there's tons of online help out there, and we're certainly here to help--the absolute LAST thing I want to do is put you off this project, but I want to be clear about the scope of your undertaking. You're making a transition from "new to computers" to, frankly, expert-level competence. You'll do it, we want you to do it, but it will not be a weekend or even a two-weekend project. For hardware, you'll need, in addition to everyone's desktop systems, 1) a computer to be your firewall, and 2) a separate computer to be your router. These can be old machines. In fact, it's a great use for old machines. > I am going to get cable broadband very soon and want to >have linux as my server. My family uses another OS besides >linux.

Can I easily adjust settings so >my teenage daughter can't log on the internet at 2:30 in >the morning? (Let me commend you on your easy acceptance of good security procedures. Your implicit assumption that a firewall is essential is absolutely correct.) Depends on what you mean by "easily configurable". Linux makes very *powerful* firewalls, by which I mean that you can do pretty much anything you want. Alas, as is common in life, the tradeoff is frequently ease of use. Many people use a special Linux distro called "LEAF", which is designed to be a firewall. Other people will roll their own, often using an application called iptables. The daughter thing sounds fairly straightforward to me (not that I've tested this, you understand); selectively block access to device eth0 (Linux's internal name for the ethernet port) based on user name and time of day. >Do I have to worry about what modem I can or can not use? Yes, unfortunately. You want to avoid the whole class of what are called "Winmodems". These are very inexpensive l'il modems that farm out all their computations to the main CPU. The manufacturers don't tell us how they work, so it's tough to get them to work. As a rule of thumb, external modems are usually OK while internal modems are usually not OK. But you won't need modems for what you're describing; modems are used to dial other modems (e.g. for dial-up Internet access). After you get high-speed access, you'll have a permanent connection. --nicole twn *** "Say you decide to call it quits after the first exam.
