• How to get Atheros ar242x wireless adapter working under Debian Linux?

  - by Mark

  Does anybody know how to get the Atheros ar242x wireless adapter working under Debian Linux (5.0.2 and/or 5.0.3)? My Debian live CDs and install CDs both don't like this card at all. Curisouly, it seems to work on other, Debian-based, Linuxes. Is this a free/non-free Driver issue? I know Debian gets mardy about that. Although for what it's worth, the Live CD doesn't seem to detect my wired LAN connection either... Specifically this is on a Samsung R610 laptop (some version of which seem to have an intel wireless adapter - this one definitely doesn't!) I've tried all sorts of things but obviously on a live CD installing software is limited. I've also tinkerering with network config files and kernel modules etc but to no avail.

• How can I fix this configure error?

  - by balor123

  I'm trying to build mosh from source on a SUSE10 machine and am getting the following error: checking for protobuf... no configure: error: Package requirements (protobuf) were not met: No package 'protobuf' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables protobuf_CFLAGS and protobuf_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. I downloaded the source to protobuf and installed it in a custom path as well. I'm not using a package manager for any of this and cannot for various reasons outside the scope of the question. I added that custom path to my PATH and rehashed. Typically, this is enough for configure but in this case its not doing the trick. I added the prefix for protobuf to PKG_CONFIG_PATH but am still hitting this error. What should I do next to get past this error?

• How to automatically show USB camera or memory stick contents in Icewm?

  - by darenw

  I normally use a very lightweight Linux setup. No desktop like Gnome or KDE, just Icewm as the windows manager and nothing else that normal users might consider essential. Well, I do need a file manager - I use Thunar. Recently I've been trying Gnome. Whenever I shove a memory stick into a USB port, or connect my digital camera, it can automatically pop up a file manager showing all the goodies on that device. KDE does this too. I like this. Although quick at the command line, I like not having to go sudo to mount the device and all that. If I want to stick with a lightweight setup using Icewm+Thunar, is there something non-huge I can install to make external devices fire up a Thunar window, or otherwise make access to the contents brainlessly easy?

• System Monitoring Redundancy

  - by Josh Brower

  I consult in a small business environment where I have two HyperV hosts (with <10 VMs) + a couple other servers. I recently had an issue where one of the HyperV hosts had a CPU issue and it came down, bringing most of my non-critical VMs with it, plus a free piece of software that I use for network & system monitoring and availability. Because of this, and the fact that iDRAC locked up to, I did not get any alerts about the crash. So I am wondering how I can (cheaply) get a redundant availability monitoring system in place--Is is as simple as running Nagios or Zenoss (or whatever) on two different HyperV hosts? It just seems like running more than one copy of Nagios/Zenoss/etc could be expensive and have high overhead. Thoughts? Thanks! -Josh

• SSH Tunnel for Remote Desktop via Intermediary Server

  - by Mihai Todor

  I've seen many examples of SSH tunnels on the nets, but I'm still having no luck with this. Here's the setup: Windows 7 PC in a private network, sitting behind a firewall, with PowerShellInsider SSH server set up and working fine. Public access Linux server, which has access to the PC. Windows 7 laptop, at home, from which I wish to do remote desktop on the PC. Now, here's what I've tried so far: SSH tunnel from my laptop to the Linux server: ssh -f my_user@LINUX_SERVER -L 6666:LINUX_SERVER_IP:6666 -N SSH to the Linux server where I've set up a tunnel to the PC: ssh -f 'PRIVATE_DOMAIN\my_user'@PC_NAME -L 6666:PC_IP:3389 -N Unfortunately, I must be doing something wrong, because it doesn't seem to work. Any ideas why or, at least, any suggestions on how can I try to debug this setup? At the moment, I have access to all 3 machines (non-root on Linux), so I can test whatever I want...

• Gentoo Linux -> Ubuntu: Can I Preserve My LVM/RAID Devices, Or Do I Need To Reformat?

  - by Eddie Parker

  Hello: I've got a Gentoo box that I'm interested in switching over to an Ubuntu box. I currently have the partitions laid out using a mixture of RAID (mdadm) and LVM2, as specified in this document [1]. Ideally I'd like to just wipe out the non /home partition, as it's got data I'd like to keep. Is it possible to reuse the current setup, or do I need to restart? vgdisplay, vgchange -a y, etc don't yield any results from the Ubuntu LiveCD, and I'm wary to run any commands that might wipe my data. Your help would be appreciated. [1] http://www.gentoo.org/doc/en/gentoo-x86+raid+lvm2-quickinstall.xml

• telnet to 3389 connects, RDP remote desktop app bails ?

  - by scott_lotus

  I can TELENT 192.168.10.10 3389 and get a connection. But RDP client to 192.168.10.10 immedietly bails (i.e less then 1 sec) "connect" button greys briefly, RDP app remains on screen. Have tried these from many nodes on the subnet to 192.168.10.10 with same result. On 192.168.10.10 Allow Remote Desktop is enabled. On 192.168.10.10 windows firemall is off. Im connecting from the same subnet i.e no firewall hardware / routers in the way. AV software is installed but other nodes on same subnet allow RDP connection using exact same AV settings (network group profile) Checked 192.168.10.10 for any additonal AV software or local firewall products. Im sure non exist. Checked regedit to ensure 3389 was the port set for listening. Seems to be an XP problem (sp3) ( 2 nodes on the my LAN have this issue) and many work fine. Thanks for any help Scott

• Does an SMTP request contain host header information (or just the IP of the targeted SMTP server)?

  - by Olaf

  We are using an external commercial smtp server for our newsletters (sending them through .NET components), and they offer two smtp URLs - smtp.critsend.com and fast.critsend.com -, and the second one is reserved for sending singular emails, the first one for bulk. Using nslookup shows that both resolve to the same 4 IP addresses (fast.critsend.com being an Alias). Question: (how) is it possible for the smtp relay to distinguish between different names? Is there something in the headers that can be compared to host headers in http protocol (I didn't find any intelligible information for a non-sysadmins)? The reason I'm asking is because we would like to use one of the IPs in our newsletter script (which works) rather than a name (in order to save DNS requests), and we are wondering about potential problems.

• How complex of a daemon should be run through inetd?

  - by amphetamachine

  What is the general rule for which daemons should be started up through inetd? Currently, on my server, sshd, apache and sendmail are set up to run all the time, where simple *NIX services are set up to be started by inetd. I'm the only one who uses ssh on my computer, and break-in attempts aren't a problem because I have it running on a non-standard port, and my HTTP server gets maybe 5 hits a day that aren't GoogleBot. My question is, what are the benefits vs. the performance hits associated with running a complex daemon like sshd or apache through superserver, and what, if any successes or failures have you had running your own daemons in this manner?

• basic device that can connect to internet

  - by Hellnar

  Hello, I am looking for a cheap solution to my problem: I need to find either an already existing common device (that is used in restaurants, bars clubs) or a cheap new device that I will distribute to those places, which can connect to internet (via the already existing ethernet or wireless based internet) and do HTTP request/receive response and retrieve information ? (For instance can a POS device connect to internet?) For a project, I need to do identity validation on several restaurants and bars and not all of them have computers. So I will be giving "cheap and easy to use devices" and non-IT personal can use it to do http request to my server and get response. All I can think of is Cell phones and SMS.

• Prevent registry changes by users

  - by graf_ignotiev

  Background: I run a small computer lab of 10 computers using Windows 7 x64 Enterprise. Our users are set up as limited users. For additional restrictions, I set up local group policy for non-administrators using the microsoft management console. Problem: Recently, I found out that some of these restrictions had been removed. Reviewing the settings MMC and in ntuser.pol showed that the settings should still be in place. However, the related registry settings were missing in ntuser.dat. I already have registry editing disabled in the GPO (though not in silent mode). Question: What is the best way to deal with this situation? Should I look into preventing registry setting changes? Should I set up registry auditing to found out how these keys are getting changed in the first place? Or should I give up the ghost and write some kind of logon script that enforces registry values if they've been change? Any other ideas?

• How to Use 3 Monitors

  - by The.Anti.9

  Right now my setup has a nice big 24" flatscreen in the center, and a 19" flatscreen to the left. And a big gaping hole on the right. I have a 3rd monitor to put there, but I'm not sure how to get the computer to recognize it. Do I need a graphics card with 3 ports? Or can I span the monitors over non SLI-Linked graphics cards? Is it possible to plug my 3rd monitor into the on-board VGA port and have it work?

• Mod_rewrite pretty url when domain/foo is a directory

  - by ModRewriter

  Starting with something as simple as: RewriteRule ^(.*)$ index.php?page=$1 What if I also want the following to work: RewriteRule ^/foo$ /index.php?page=foo #/foo IS a directory This seem to work ONLY if the R flag is set, but then the full non-pretty url is written. Thus it seems I can REDIRECT existing directory, but not rewrite them... Maybe with an .htaccess inside the directory itself? Or some PHP magic in /foo/index.php like header(/index.php?page=foo)? Will it work? Will it be HTTP standard/search engine optimized? Please help! PS: The oddest idea occurred to me: redirecting /foo to /not-a-dir, and then rewriting /not-a-dir to /index.php?p=foo should theorically work... But... Come on... Really?!?

• How to use a custom Windows 7 system drive letter?

  - by Ivan

  The subject PC has many hard drive partitions dedicated for different purposes, C: being a Windows XP system drive and F: (which is actually the next primary partition placed right after C: physically) being intended to host a newly installed Windows 7 instance (meant for "dual boot" configuration). Needless to say the intention was all the partitions to have exactly the same letters under both OSes, needless to say Windows 7 has detected all of them in a completely different order which would not be a problem (as the non-system drives letters can be changed easily after installation) if it wouldn't have named it's system drive C: (meant to be F:), which I have no Idea how to change. Is there a way to set the letter you want? I don't mind reinstalling Windows 7 from scratch if it is to be set at installation time or even configured in some text files on the installation DVD. I have tried this way, but it renders the Windows 7 system desktop unbootable (gets stuck on "Preparing your desktop..." after "Welcome").

• Notepad/Edit equivalent for Linux command line

  - by Jason Kester

  I'm looking for a simple text editor that I can use from the command line in Linux to edit files. I'm used to editing files in windows, so I'm looking for something with the same keyboard interface. That means: SHIFT+Arrow Keys/PGUP/PGDN to select text CTRL+C, CTRL+X, CTRL+V to copy/cut/paste And that's pretty much it. Surprisingly I'm having a tough time finding something like this. Vi/emacs are naturally out. Nano comes close, but has its own non-standard cut/paste/select keyboard shortcuts. Surely this thing exists somewhere. Thanks in advance for pointing me in the right direction.

• Spam just keeps on coming

  - by Campo

  I administer a Windows Server 2003 with Exchange 2003 as well as GFI installed. I am watching the GFI dashboard and every third email is spam. Not only that it goes to a non existent address then the [email protected] sends out an NDR to the sender. Should I be worried about this? I know it is directory harvesting but we have directory harvesting turned on in GFI and I do see it is working but obviously doesn't work for emails that don't exist. My issue is I would turn off NDR but then people who legitimately mistype and email address to our domain will never know their email did not get to the recipient. What do others do to combat spam? Is 3 times the amount of spam to ham normal? We filter out 90% of the spam but some does get into the users inbox. Thanks for the suggestions and advice!

Recently i have noticed performance issues when my girlfriend was playing Sims 3, and then one day i turned it on and all i got was a thick white line at the bottom of the screen. i heard the OS start up so automatically i thought it was a damaged screen, but i had doubts so i plugged it into an external display via the vga port. it worked but everything appart worm the OS choice menu looks distorted beyond belief. even the bios screen had multicoloured lines running down the screen. The resolution is non existant, the screen only shows a 256 colour pallette and is heavily distorted. i barely managed to get to the device manager where i found the gfx card with an exclamation mark. does anybody have suggestions? should i buy a new mobo or are repairs possible? thanks in advance

• Linux kernel with grsec + Java / Apache Tomcat

  - by NoozNooz42

  I've got a Debian Linux 64 bit dedicated server. The kernel has the grsec patch applied. I'm mainly using this server to run Apache Tomcat (6.0.26, Java 6) and everything seems fine. The only issue, is that when I start Tomcat, I get a few of these: grsec: From xxx.xxx.xxx.xxx: Segmentation fault occurred at 00007fefe04e4000 in /home/t/jre1.6.0_20/bin/java[java:22403] uid/euid:1001/1001 gid/egid:1001/1001, parent /sbin/init[init:1] uid/euid:0/0 gid/egid:0/0 grsec: more alerts, logging disabled for 10 seconds Then no error logs anymore. Everything is fine. The kernel is: Linux 2.6.32.2-xxxx-grs-ipv4-64 #1 SMP Tue Dec 29 14:41:12 UTC 2009 x86_64 GNU/Linux And the webapp works fine. So there are segmentation fault when Tomcat starts, but everything seems to works fine. Is this concerning? Should I move to a non-grsec kernel?

  I'm completely helpless, maybe you guys can help me out. I installed PostgreSQL under my new MacOSX Lion. When I try to connect to my localhost with pgAdminIII.app it says: Error connecting to the database: FATAL password authentication failed for user postgres I just have no idea what to do? Non of my passwords work. Neither my adminpass nor "postgres" nor anyhting else. I tried to install it again via the console where I found this helpful link: http://www.peerassembly.com/2011/08/...resql-on-lion/ However the problem is, that when I try to run createuser -a -d _postgres the same password problem appears again. I just can't seem to find a solution to this. Always wrong password. Btw. I have a new User called "PostgreSQL" on my machine after I installed postgres. Any ideas? I'm so stuck and I really need to make this work.

• Redirect To Domain Before SSL Is Read

• Facebook doesn't work on computer, but work on mobile device, both use the same router

  - by sasa

  I have a very strange problem and I'm thinking that can be problem with dns or something similar, but not sure and don't know how to solve. My computer is connected to router and every site works fine except facebook (Chrome and Firefox). Chrome shows "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." But, on mobile device witch is connected to the same router facebook works fine (Fb application and Delphin browser). Pinging facebook works fine. Clearing cookies and cache didn't help. Also, I performed antivirus and antimalware scan and there is nothing. What can be a problem? Update: I'm also connect notebook on that wifi router, and on it works fine. nslookup facebook.com Server: UnKnown Address: 192.168.1.1 Non-authoritative answer: Name: facebook.com Addresses: 2a03:2880:2110:3f01:face:b00c:: 2a03:2880:10:1f02:face:b00c:0:25 2a03:2880:10:8f01:face:b00c:0:25 69.171.224.37 69.171.229.11 69.171.242.11 66.220.149.11 66.220.158.11
