Juan-Mariano de Goyeneche

I've promised to place some documents available via web, and it seems I need a kind of "central page" which redirects to the rest of them.

Lo siento, es un tanto vergonzoso, pero aún no he tenido tiempo de escribir una versión de esta página en español. Cuando tenga tiempo, uno de estos años...:-( Lo que sí tengo son unos cuantos artículos que he escrito en revistas españolas. La lista está justo debajo de esta nota.

Sorry, I'm very ashamed, but a Spanish version of this page is not available yet. When I have time, one of these years... :-(

Some papers of mine.

Some hacks of mine.

• I have modified the Linux talk/talkd to make them compatible with SunOS/Solaris' talk. As you know, Sun is using a different talk protocol than anyone's else. I plan to send my diffs to the Debian GNU/Linux distribution, but I am alpha-testing them now. If you want to download it (tar.gz), please let me know any bug you find. Thanks!
• In order to learn Sun's talk/talkd protocol, I needed to have a look at the packets exchanged between SunOS talks. Unfortunately, tcpdump shows only hex dumps, not ASCII ones, which is most useful with some protocols. So I modified tcpdump to get also ASCII dumps. I think original authors made it deliberated to have dumps only in hex, and they are not interested in the patch, but if you are, get it here. The patch is against Debian's tcpdump.
• All GNU/Linux tcpdump ports I have seen give centiseconds resolutions. The problem is either in libpcap or in the timestamps the kernel places into the packets it receives. Anyway, I have changed libpcap so that it gives microseconds resolution (by calling gettimeofday(2)) and makes me happy. On heavy load the time got from gettimeofday(2) might be far from the time the packet arrived, but... Here is the patch against Debian's libpcap.
• Normally, I use mailx to send mail and mutt to read it. The problem to me with mailx is that it doesn't allow you to change the "From:" field, what is very useful when subscribing to mailling lists. I was told that SunOS' mailx provides this feature via the "EMAIL" env. variable, and I added it to Linux's mailx. Anyway, "sendmail" often dicides that it knows what your "From:" is and you don't, so it may be useless to you depending on your MTA. It does work with qmail. And... it seems I can't find the patch either... I'll add the link as soon as I have something to link it to...
• I usually connect to the Internet from different ISPs. It's quite annoying to discover that your browser has a proxy entry that is not valid for the current ISP and loose time (and money :) ) changing it. I wrote fake_proxy to solve it: I tell my browser that the proxy is in localhost:32768 (or whateever port you like). At that time, fake_proxy is already launched and bound to that port. When the browser asks it for data, it recognices the ISP you are connected to and forwards the "call" to the correct proxy. When not connected, it can redirect the browser to your local webserver (your apache at localhost).
