Re: [gentoo-user] Touch screen
* Rodrigo Forlin [EMAIL PROTECTED] wrote: Can someone point me a touch screen monitor that works under console? I bought a Touchscreen from some car-tuning guy on ebay. The touchscreen is detected as an eGalax compatible unit and works using the usbtouchscreen-module of the linux-kernel (using 2.6.19-gentoo-?). Works as in the cursor moves when I touch it. I had to patch the kernel to add some sysfs-entries to be able to calibrate it without X. I sent the patch to the maintainer some days ago, who has not repiled yet. If anybody is interested in the patch, please ask. I develop programs under console using framebuffer so i need also a nice api to make my programs work with touchscreen. I use pygame with the fbcon SDL-Driver, that works without any problems. Some rough project overview and screenshots can be found at http://www.spida.net/projects/pympdtouchgui/, code will follow.

[gentoo-user] Touchscreens under linux
Hi! For my Musicbox[1] project, I am looking for a way to control a mpd[2] with a touchscreen. The device I have in mind is a 10,2 VGA / USB touchscreen. I assume it is supported by linux. If I understand correctly, the touchscreen is (if used correctly) just another way to control the mouse pointer. Is that right? Do I have to use X to use the touchscreen, or can I use it with gpm or SDL? Does anybody know a client for mpd ([2]) that works without X an can be controlled with a touchscreen? Maybe using SDL? If there is no client that works without X, does anybody know something that will work as an onscreen-keyboard?

[gentoo-user] Bookmarkmanager
Hi! I am looking for a bookmark-manager for linux. It should import/export (at least) firefox and opera bookmarks, and should be able to synchronize between several browsers on several machines. Textmode would be cool, as I intend to run it from a script. Has anybody seen something like this? Timo -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] {OT} recovering data from a Memory Stick
Hi Grant, * Grant [EMAIL PROTECTED], 06.04.2006, 22:39:11: Is it possible to recover data (photos) that have been deleted from a Sony Memory Stick? It depends. On what happened, what you do next, and the amount of time (or money) you are willing to invest. How can I get a look at what is really in there? Use dd to make a backup (that is, copy the contents of the stick (the raw bits, not the files) to your harddisk, and work on that copy. You can use your favorite hex-editor (there are a bunch of them in portage) to recover the directory-structure (or what is left of it). :-) You won't have ANY success with it, if you don't understand a bit about filesystemstructure and how to use the tools you want to use. Its very likely that you will destroy data if you are not careful. There are a few things you can try, depending on your knowledge. You could use the forensic toolkit sleuthkit (and perhaps its web-frontend autopsy). For recovering photos, I have had good results by just searching for jpeg-headers (first 4 bytes, assuming you have jpeg-images, ofcourse) and simply cutting a bit more than your average filesize after the header. Result of that will depend from your usage pattern on the Memorystick, that is, if you delete all files, than make new photos, or just delete some files (which results in fragmentation, which will prevent the copy-x-kb-after-jpeg-header- approach). There are some other ways, but these are the simple ones. In any case, MAKE A BACKUP!!! before you try to recover the files. HTH.

Re: [gentoo-user] iptables example on Gentoo
Hi Dave, * Dave Nebinger [EMAIL PROTECTED], Friday, September 9, 2005, 4:23:07 PM: Dude, trying to use iptables directly was your first mistake. no, it wasn't. I have written some small example script http://forums.gentoo.org/viewtopic.php?p=377447 that (IMO) is quite modular... Yes, Timo, it is quite modular and quite thorough. It represents a great job at developing a general set of rules. But I would raise the following issues: 1. FTP support: You've allowed for the active ftp protocols on ports 20 21, but what about passive? This traffic will usually be on the higher ports (typically a range specified in the configuration for the ftp daemon). I do believe that if the ftp daemon tries to open a passive connection outbound it's going to get knocked off at the knees. If I open a ftp-connection from the inside to a ftp-server on the outside, it should get caught by the iptables-ftp-module and the RELATED rule. 2. Measure the checks: The more checks that a packet goes through, the longer it will take to travel through the iptables stack. Your script has a lot of checks in it. Consider a pgp packet as it traverses all of the chains etc. that you've specified. You're probably looking at 30+ checks at least (although I haven't counted each individual check, but I'm confident it is quite a large number). That's a significant number of hops and means the packet is going to be hanging around on the box a lot longer than what it really should. Yes, I have MANY checks. I have had no probleems while using this and some newer versions of this script. However this seems to bee a problem for users that get many small packets per time-unit... (think p2p here). As you state below, this is no universal solution, but was built to be easily reconfigurable. 3. No detail on why the checks are ordered in the way they are (is there an order?): As #2 indicates, the increased number of checks that a packet needs to be pushed through means it will hang around on the box longer. Therefore they should be ordered to give priority to either a) heavily used ports or b) ports you want to have processed sooner rather than later. There was no reason ;-). see above 4. No reason for accepting specific outbound traffic: I tend to prefer allowing all outbound traffic and filter on those ports that shouldn't be going outbound (i.e. dhcp responses, dns responses, ipp packets, windows networking stuff, known trojan/virus ports). It greatly reduces the number of checks outbound traffic needs to go through. I filter outbound for various reasons: generally, I like to know what happens on my internal network. You can catch misconfigured software some malware and some bad users with that. Obviously to improve the throughput you'd have to alter the script to use multiple ports on accept lines. Once you start doing that, though, you lose the modularity that you've built into the script. You are probably right in that. The point that needs to be made is that there is no 'one iptables script fits all'. Each site, each box for that matter, has it's own set of services and it's own usage criteria. To that end the iptables rules will (should) always vary from box to box, whether it is a server, a desktop, a gateway, or some combination of the three. Of course. New users looking to get their boxen online grab scripts like this thinking they are going to secure it for them, yet they don't understand the nuances of the individual rules nor how they are grouped. How many folks that grab the script are going to know what the teamspeak or pgp ports are for and whether they need them or not? How many are going to know that they've exposed their system to incoming teamspeak packets, whether they have teamspeak or not? Even more: They are exposing their box to ALL packets on the teamspeak port. But IMO, it's easier to learn than some gui-things, you don't have to transfer it over network to your firewall-box (who has X on a firewall??? :-) ) and its easy to reconfigure. Thanks for the feedback. really. Timo -- gentoo-user@gentoo.org mailing list

I also have another machine (Machine 2) that will hold the backup. Machine 2 can see (make requests to) Machine 1, but the opposite isn't true.
