IP-tunnel

2002-05-29 Thread Kalle Hasselström
Jag har en kompis med en egen Debianburk som sitter bakom en henskt
elak brandvägg. Han får inte ens en publik IP-adress, vilket innebär
att han kan ringa ut, men ingen kan ringa in till honom.

Vi försökte överföra varandras röster i realtid för att kunna prata,
men vi kunde inte hitta nåt enda telefonprogram som inte använde UDP,
och jag kan inte ens skicka såna paket åt rätt håll eftersom han inte
har nån publik adress. Det slutade med att vi gjorde varsin pipe med
brec, oggenc och nc i den sändande änden och nc och ogg123 i den
mottagande. Han fick ringa upp mig för att starta båda
TCP-kopplingarna, naturligtvis. Det hela fungerade jättebra, bortsett
från att fördröjningen var typ 20 sekunder, ungefär som att prata med
någon som befinner sig hyfsat långt ute i rymden.

Finns det något bra sätt att tunnla UDP? Jag ser framför mig nån smart
mojäng som ger oss varsin ny ethX som bara existerar i mjukvara, och
som sitter ihop med en TCP-koppling, så att det för alla program som
använder dessa interface ser ut som att datorerna är ihopkopplade
direkt med en sladd. Finns det nåt sånt, eller nåt som kan duga lika
bra?

tangentbordsknapp som musknapp

2002-05-23 Thread Kalle Hasselström
Jag har en laptop vars touchpad bara har två musknappar. Då får man
trycka på bägge samtidigt för att få ett klick med mittenknappen,
vilket är ganska jobbigt.

Jag har också använt xmodmap för att stänga av CapsLock, eftersom jag
bara irriterar mig på den tangenten.

Vet någon om det går (och i så fall hur man gör för) att få
CapsLock-tangenten att generera samma X-event som mittenmusknappen
ger?

svensk avstavning i LaTeX

2002-05-15 Thread Kalle Hasselström
Jag använder följande rad i mina .tex-filer om jag skriver på svenska:

\usepackage[swedish]{babel}

Det gör att diverse saker blir på svenska (t.ex. Figur 1 istället
för Figure 1), och säkert en massa annat också som jag inte känner
till. (Om nån är på förklararhumör ... :-)

Men. En sak som ska hända är att avstavningsregler specifika för
svenska ska användas. Det verkar inte som att det blir så, för när jag
kör

$ latex minfil.tex

så skriver den bland annat det här:

Package babel Warning: No hyphenation patterns were loaded for
(babel)the language `Swedish'
(babel)I will use the patterns loaded for \language=0 instead.

Är det något speciellt Debianpaket man måste ha för att få nån fil som
den letar efter (och inte hittar), eller vad?

(Jag kan inte verifiera att avstavningen inte fungerar i alla fall,
eftersom en del ord faktiskt blir avstavade. Men inte många; kanske
får den så stora mellanrum att den bestämmer sig för att avstava trots
att den inte vet hur?)

Thanks, it works great! Though with no local mirror, the download was

Who exactly are blackdown? Are they making their own jvm and stuff, or
do they tweak sun's code or what? (And in that case, why?)

 Kalle,
 
 I'm a large fan of bsd-ftpd.  It's simple to install and straight forward
 to configure.  First off after you run apt-get install bsd-ftpd you
 should open a new shell and type man in.ftpd.  Read that file over and
 you will find a direct howto on how to configure your ftp directories and
 what files should or shouldn't be there and with what permissions.  As
 one poster notes, be careful with your incoming directories permissions.
 For example, I have mine set to 000 until I'm ready to actually upload
 something, then I ssh into home, chmod the incoming directory to 777 and
 upload, then change it back.  If you leave it wide open you will be
 hosting pirate sites in no time.  Good luck.

This was my size! proftpd seems very nice, but all I want to do is
enable ftp uploads/downloads for _one_ user account (mine).

Two more questions popped up, regarding inetd. bsd-ftpd is started by
inted on incoming calls. How can I

a) Temporarily disable ftp? I thought it would be a good idea to do
this when it's not being used, to be on the safe side. I won't be
using it much at all, not even once a week.

b) Change the port? The default port for ftp is 21, but I'd like it to
use 12345 or something instead. This is just to confuse people,
especially my ISP who with a rather sweeping statement disallows
servers. They just want to keep the traffic volume down, and I won't
be generating overly much traffic, but nevertheless I thought it might
be prudent to assume that they check for requests on ports 21 and 80.

 IIRC xinetd allows you to set date/time based access controls.
 You could do more with a wrapper around in.ftpd, if you can
 write a wrapper like that. You could go as far as write a wrapper 
 that needs a specific packet -- if it receives that, it spawns 
 ftpd, otherwise it drops the connection (knock first, often used 
 by trojans). Or you could run ftpd standalone, ssh to the box and 
 do /etc/init.d/ftpd start before ftp'ing.
 

Good idea! The following does what I want:

[contents of /usr/local/sbin/in.ftpd]
--
#!/bin/sh

# Run the real in.ftpd, but only if the file /etc/allowftp exists.
if [ -e /etc/allowftp ]; then
/usr/sbin/in.ftpd $*
fi
--

It's an on/off switch that's only reachable from the inside.

  b) Change the port? The default port for ftp is 21, but I'd like it to
  use 12345 or something instead. This is just to confuse people,

 Would
 12345 stream tcp nowait root /usr/sbin/tcpd /usr/sbin/in.ftpd -q
 work? Also, you can tell standalone server what port to listen to,
 e.g. Port 12345 for ProFTPD.
 

Works like a charm (note that it's been modified to call the wrapper
script instead as well):

[slices from /etc/inetd.conf]
--
#ftp   stream  tcp nowait  root/usr/sbin/tcpd

setting up an ftp server

2001-07-29 Thread Kalle Hasselström
Currently, the only service I'm running is ssh, as this meets my
requirements both regarding remote logins and file transfers. However,
ssh clients, especially the file-transfering sort, are not a standard
item on most mac and windows computers, and now and then I find the
need to talk to my computer from the strangest places (for example, I
need to scan a bunch of images, and the only scanners I have easy
access to are hooked up to Macs).

How much of a security risk would it be to run an ftp server? Is the
biggest risk the clear-text passwords (I won't be transferring
confidential files, I just don't want anyone to break in), or are
there other major security holes as well? Would I be reducing the risk
by just running the server while I need it (I'm the sole user on my
box), or might I just as well leave it running?

What server should I install? I found several with apt-cache search
ftpd. I want one that's safe, convenient for a one-user system, safe,
easy to configure (and hard to misconfigure), and safe. Any
recommendations?

Re: Mutt and KMail harmony?

2001-07-25 Thread Kalle Hasselström
On Wed, Jul 25, 2001 at 10:25:25AM -0400, Jason Rashaad Jackson wrote:
 Hello all:
 
   I presently use both KMail and Mutt to check my e-mail.  Fetchmail grabs my 
 e-mail from an IMAP server and stores it locally in /var/mail/jrashaad.  If 
 KMail isn't running, I use Mutt remotely to check my mail (leaving it in 
 /var/mail/jrashaad).  If KMail is running it picks it up, filters it, and 
 sticks it in various folders.
 
   The problem comes when I try to view one of those folders in Mutt.  I have 
 no problem viewing the folder and reading the e-mail, however when I try to 
 look at the same folder in KMail, suddenly the headers are wrecked, and KMail 
 switches the subject to 'No Subject' and the sender to 'Unknown'.  Checking 
 the folder again in Mutt, everything looks fine, but KMail refuses to touch 
 them from that point on.
 
   I think my solution might be stop using KMail, and just set up procmail to 
 do the filtering that KMail is doing now, but I'd rather keep using it.  Any 
 advice?  Here's my info:
 
 Debian v.2.2r3 (Kernel 2.4.5)
 Qt v.2.3.0
 KDE v.2.1.2
 KMail v.1.2
 Fetchmail-SSL v.5.8.3
 

I considered using the pair KMail/mutt as well, using procmail for
sorting. However, I decided against using that after reading in the
KMail docs that other programs must not touch the mboxes that KMail
use while KMail is running -- I think it said there would be
consistency problems or some such. And that would happen, since I've
set fetchmail to deliver mail every 15 seconds.

If you take a look at your ~/Mail directory, you'll see that for every
mbox file foo, KMail has created a .foo.index file (or something like
that). It doesn't seem too far-fetched to assume that KMail uses those
files to store headers and such for quick retrieval, and if that's the
case, editing only foo with another program is sure to make the info
in .foo.index invalid. But KMail doesn't know that ...

This is all just speculation, but if I'm right, you simply can't use
KMail in parallel with another mail program. Unless you store all your
mail on an IMAP server; IMAP was designed with something like this
situation in mind. Mutt has IMAP support, and KMail will have very
soon (just wait for KDE 2.2). If you don't want to or can't store all
your mail on the IMAP server you already mentioned, you could always
run your own.

However, using fetchmail+procmail+mutt is a very good solution. That's
what I use, and I'm very happy with it. But I want KMail too, so I
might just set up an IMAP server myself.
