VNC is already using display 0, so you would have to do: startx -- :1 Question, though. The whole point of VNC is that you have an X desktop open from the remote machine. Why start *another* X session on top of it? Instead, on the remote machine, there should be a ~/.vnc dir, create a file called xstartup, make it executable, and then edit it to start whatever desktop or window manager you want to run on VNC. -- JoeHill ++ ICQ # 280779813 Registered Linux user #282046 Homepage: www.orderinchaos.org +++++++++++++++++++++++++++ "I'm even lethal when I'm unarmed, 'cuz I'm louder than a bomb!" -- Chuck D. -- The Toronto Linux Users Group.

I installed VNC on a RH 9.0 server. It installed fine, but when I connect to it using my VNC prog and try to run X, I get the following error: [root]# startx Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again. Any ideas? Thanks, Sidney

Debian attacker may have used new exploit

Forensics revealed a burneye encrypted exploit. Robert van der Meulen managed to decrypt the binary which revealed a kernel exploit. Study of the exploit by the RedHat and SuSE kernel and security teams quickly revealed that the exploit used an integer overflow in the brk system call. Using this bug it is possible for a userland program to trick the kernel into giving access to the full kernel address space. This problem was found in September by Andrew Morton, but unfortunately that was too late for the 2.4.22 kernel release. This bug has been fixed in kernel version 2.4.23 for the 2.4 tree and 2.6.0-test6 kernel tree. For Debian it has been fixed in version 2.4.18-12 of the kernel source packages, version 2.4.18-14 of the i386 kernel images and version 2.4.18-11 of the alpha kernel images." Also covered in MDKSA-2003:110: Problem Description: "A vulnerability was discovered in the Linux kernel versions 2.4.22 and previous. A flaw in bounds checking in the do_brk() function can allow a local attacker to gain root privileges. This vulnerability is known to be exploitable; an exploit is in the wild at this time. The Mandrake Linux 9.2 kernels are not vulnerable to this problem as the fix for it is already present in those kernels. MandrakeSoft encourages all users to upgrade their systems immediately." What confuses me, is that my default install of MDK 9.2 shows kernel version: 2.4.22-10 But MDK says 9.2 is safe.

Backup suggestion
by jason-gaRZxGPHtpBxZtjKW1aY+1aTQe2KTcn/＠public.gmane.org 02 Dec '03

02 Dec '03

I have an idea that I would like to put out and get some input on. I am currently converting over numerous windows home users to linux. I want to implement a backup & restore scenario that is idiot proof, and that the individual users can recover from at their leisure. ( without tech support from me ) My idea is as follows. 1: Using cron to archive the users /home directory at regular intervals - time of day would be set by a config file set by root. Use of mondoarchive I feel would be of great benefit. There would have to be settings and checks based on disk space allocations and availability. I would prefer both a differential backup system as well as having a known good configuration as a last resort. 2: When a user goes to logon, at the bottom of the window manager selection list, there would be a "Restore from backup" option ( linking to a script that would initiate the recovery process ). this would prompt the user, indicating the possibility for loss of data created since last backup ( an indication of last backup by a timestamp would be good ) before finally recovering from the backup. Would this be possible? feasable? Is there already a tool out there to accomplish this? Any input would be appreciated. -- " Eventually people tire of repairing broken Windows, And decide to replace them with something stronger" (o_ //\ Linux - The Choice Of A GNU Generation V_/_ Jason Shein Linux Registered User #281100 jason-gaRZxGPHtpBxZtjKW1aY+1aTQe2KTcn/(a)public.gmane.org -- The Toronto Linux Users Group.

SOT: shitfs in spam trends and topics
by blsonne-bJEeYj9oJeDQT0dZR+AlfA＠public.gmane.org 01 Dec '03

Greetings, SOT = Somewhat Off Topic, though if there is a another acronym in more common usage let me know... Is there anyone out there that has paid attention to the trends in spam, in particular topics? Perhaps created a list of some kind, or a tree structure ie. financial, health, etc. and broken down further, of course. Database might be a better description. I don't want it for spam filtering, although that would be a great idea now that I think of it, but more for curiosity's sake. Lately I've been getting blasted by colon cleansing products, no pun intended ;) Is anyone else getting this? Another trend, although a somewhat longer one and at a low level of occurrence, are penis enlargement ads that have taken to insulting me. "Satisfy your woman, you pin-dick" was the most harsh, and perhaps relatedly, the funniest one as well. If aggressive derision toward a potential customer helps make you money then I should have been rich long ago! Later, B -- The Toronto Linux Users Group.
