Re: affichage déporté (fwd)
-- french --- Bonjour, Il suffit de lancer xterm avec la commande xterm -display serveur:0.0 Pour dire l'ecran 0 du poste 0 nomme serveur. Il est probablement plus efficace de changer la variable d'environement DISPLAY $ DISPLAY=serveur:0.0 $ export DISPLAY ( dans un shell bourne) ou $ setenv DISPLAY serveur:0.0 (sans un shell c) Ce qui permet d'afficher toutes vos applications sur serveur:0.0 . .. Notez que si vous etes connecte par ssh (a partir de serveur) cette variable devrait deja etre initialisee et contenir la bonne valeur. Pour verifier l'etat d'une variable environement vous n'avez qu'a $ echo $NOM_VARIABLE Ciao. Robert. Bonjour, J'ai un petit pbm pour d?port? mon affichage X. Sur le poste ou mon serveur X tourne, j'ai fait xhost +. Sur le client, je lance l'applicarion xterm -display serveur:0 Et il me dit Can't open display: serveur:0. Quelqu'un aurait-il une id?e pour rem?dier ? ce probl?me, car ? part un xhost +, je ne vois pas ce que je peux faire. Merci.

Re: Break-in? /usr/lib/telnetd, port 1037
Date: Mon, 14 Jan 2002 14:49:36 -0600 From: Kent West [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: debian-user@lists.debian.org Subject: Break-in? /usr/lib/telnetd, port 1037 Resent-Date: Mon, 14 Jan 2002 15:53:52 -0500 (EST) Resent-From: debian-user@lists.debian.org I've got a Debian box (2.2.17, mostly woody) that I've just discovered has a more-or-less hidden telnetd running on port 1037 as well as the normal telnetd on port 23. I thought I had uninstalled telnetd (although it's possible I forgot to remove it). I'm thinking that somehow I've been broken into. I've got a pretty good Unix admin (not Debian) here helping to take a look at it, but so far she's not been able to learn anything definitive. One thing she thought odd was the existence of the directory /usr/lib/telnetd. And here's what one of the security gurus on one of her security mailing lists had to say about it: There should not be a /usr/lib/telnetd. As you mentionned this is only a directory and not the actual binary of telnetd. This directory contains the login program that telnet uses to authenticate users. You have been hacked. This is NOT normal behavior. exacutables should never be stored in /usr/lib thats for libraries. There should also NOT be a telnetd user in our password file. ftp maybe NOT telnetd. /etc/services is just for mapping ports to services. You could delete it and everything in inetd.conf would still work. You just wouldnt get a nice port to name mapping from netstat;-) 1) is it normal for a Debian box to have telnetd as a user, as a member of utmp, and to have the /usr/lib/telnetd directory? I don't believe that's a problem. As soon as you install the telnetd package you have a telnetd user in /etc/passwd. It should however not have any passwd in /etc/shadow . . . But it's abnormal to have a hidden telnet server on port 1037. You should look into that. Robert Walker.
Re: root login problems
You could have a look at the /etc/securetty file. The file contains the list of the tty's root is allowed to use to login directly. $ man securetty could be helpful. Robert Walker.

I have run passwd root and entered the new password with the verification being accepted, so I think that's not the problem, but I don't know.

problems upgrading to 2.2r4
Hi, I am having difficulties upgrading to version 2.2r4. I ran $ apt-get update $ apt-get -u dist-upgrade and the following error keeps coming up : You might want to run `apt-get -f install' to correct these. Sorry, but the following packages have unmet dependencies: python-gnome: Depends: libglade-gnome0 but it is not installed E: Unmet dependencies. Try using -f. when I try to install libglade-gnome0 I always get the following error: $ apt-get install libglade-gnome0 Preparing to replace libc6-dev 2.1.3-13 (using .../libc6-dev_2.1.3-19_i386.deb) ... dpkg (subprocess): unable to execute old pre-removal script: Permission denied dpkg: warning - old pre-removal script returned error exit status 2 dpkg - trying script from the new package instead ... dpkg (subprocess): unable to execute new pre-removal script: Permission denied dpkg: error processing /var/cache/apt/archives/libc6-dev_2.1.3-19_i386.deb (--unpack): subprocess new pre-removal script returned error exit status 2 dpkg (subprocess): unable to execute post-installation script: Permission denied dpkg: error while cleaning up: subprocess post-installation script returned error exit status 2 even if I try not to install python-gnome (using dselect for example) or run $ dpkg -f install I always get similar errors (Permission denied) $ dpkg --remove --pending (Reading database ... 18378 files and directories currently installed.)
