• Using WSUS Admin Console from outside domain

  - by Nick

  Environment: I have a workstation on our primary domain. We have a primary WSUS Server that is the upstream server of 8 different testing domains. The Primary WSUS server is not part of any domain. Routing is configured between my workstation and the Primary WSUS server. I can RDP to the Primary WSUS sever without any problem. The router is configured to forward any any between my workstation and the Primary WSUS server. This WSUS server cannot be part of a domain due to external requirements (I can't change them) on the lab I work in. The version of WSUS is WSUS 3.0 SP 2 What I want to do: I need to connect to the WSUS server with the WSUS Admin console from my local workstation. The end goal is to connect via Powershell and manage with that. I also need to take what I do here and port it to the 8 test domains so I can manage those WSUS servers. The routing is all in place so I can talk to the servers, it's just connecting to the WSUS console that is causing problems. The problem: I cannot get my workstation to connect to the WSUS Console. I get one of the following errors depending on the setup. 1st error: Cannot connect to 'WSUS'. You do not have the permissions required to access this WSUS server. To connect to the server you must be a member of the WSUS Administrators or WSUS Reporters security groups I also get the warning 7012 from the event log that says the same thing. 2nd error: Cannot connect to 'WSUS'. The server may be using another port or different Secure Sockets Layer setting. What I have tried: So far I have configured IIS for Anonymous Authentication on both the WSUS Administration and ApiRemoting30 using an account will call WSUS_User. With this in place, I get the 1st error. When I do this though, the local WSUS Console cannot be used either. Reverting back to only Windows Authentication allows the local console to work, but the remote console now give the 2nd error. I have confirmed the port, and that there is no SSL in use (which is a policy that is pushed from above, that I cannot effect). I have placed WSUS_User in the groups mentioned above, but it still does not connect. I made sure WSUS_User has full access on C:\Program Files\Update Services and C:\Program Files\Update Services\WebServices I am not very familiar with the workings of WSUS or IIS, and have gone as far as I can figure out on my own. Googling these errors all take me to the same steps about Anonymous Authentication and configuring permissions on folders. Note: I have cross-posted this to StackOverflow as well.

• Why Does Wireless Gear Degrade Over Time?

  - by bahamat

  I saw this originally posted on slashdot, but their comment format is not conducive to actually getting a correct answer. Having directly experienced this phenomenon myself, I'm now asking here where I think I can actually get an educated answer. Here's the original question verbatim: Lately I have replaced several home wireless routers because the signal strength has been found to be degraded. These devices, when new (2+ years ago) would cover an entire house. Over the years, the strength seems to decrease to a point where it might only cover one or two rooms. Of the three that I have replaced for friends, I have not found a common brand, age, etc. It just seems that after time, the signal strength decreases. I know that routers are cheap and easy to replace but I'm curious what actually causes this. I would have assumed that the components would either work or not work; we would either have a full signal or have no signal. I am not an electrical engineer and I can't find the answer online so I'm reaching out to you. Can someone explain how a transmitter can slowly go bad? Common (incorrect, but repeated) answers from slashdot include: Back then your neighbors didn't have wifi, now they do. They drowning you out. I don't think this is likely because replacing the access point with a new one and using the same frequencies solves the problem. Older devices had low transmit power. Crank that baby. As mentioned by a FreeBSD wireless developer this violates regulations and can physically damage the equipment. It was also mentioned that higher power in one direction is not necessarily reciprocated. This shows higher bars, but not necessarily a better connection. Manufacturers make cheap crap designed to wear out. This one actually may be legitimate although it is overly broad. What specifically causes damage over time? Heat? Excessive power? So can anyone provide an informed answer on this? Is there any way to fix these older access points?

• xterm not wrapping text properly

  - by mulllhausen

  I'm configuring both my gnome-terminal and xterm columns (i still haven't picked which of these I will be using) and I have a couple of issues I would like to fix: the typing area seems to be smaller (fewer columns) than the display area the typed text is not wrapping to the next line when it reaches the end - it just continues back around on the same line, overwriting the prompt (i have set a custom bash prompt with PS1 in case this is relevant) $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 7.1 (wheezy) Release: 7.1 Codename: wheezy $ echo $TERM xterm $ stty -a [peter@pc ~] $ stty -a speed 38400 baud; rows 52; columns 126; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?; swtch = M-^?; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 hupcl -cstopb cread -clocal -crtscts -ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc ixany imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke $[peter@mine ~] $ # the column width only goes up to here ------------------------------------------------> the results are identical in both the xterm and in gnome-terminal 3.4.1.1 and as you can see, the output of the stty -a command goes right up to the edge of the screen, while the typing does not go that far. I have found that I can get the desired result by setting the columns to a very large number, eg: $ stty cols 1800 this fixes both problems. Is it the right way to go about solving this problem? Will this "break" any of the output from programs? So far I have tried top and stty -a and these seem OK. more info as requested in the comments i found that if i cat some input into a file then the columns actually strech the full width of the terminal window: [peter@mine applications] $ cat > /tmp/asd aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaasssssssssssssssssssssssssssssssssssssssssssssssssssssssssssqqqqqqqqqqqqqqqq qqqq does this imply that it is actually bash that is restricting the number of columns and not the terminal? if so then how to alter the number of columns in bash?

• Low framerate on background apps

  - by user1698923

  My problem is that when a game is running in the foreground, in Full Screen mode, any applications on my second monitor (such as youtube videos, videos, not app specific) drop their frame-rate to about 2-3 FPS. It seems like some sort of power management option that I can't track down. As far as I can tell, it's not due to the GPU not being able to keep up. For instance, my PC can play League of Legends at about 280FPS when the framerate is uncapped. If i cap it at 60FPS using the in-game option, it has no affect on the performance of the background app. Summary Operating System Windows 8 Pro 64-bit CPU Intel Core i7 3820 @ 3.60GHz 42 °C Sandy Bridge-E 32nm Technology RAM 12.0GB Triple-Channel DDR3 @ 533MHz (7-7-7-20) Motherboard Gigabyte Technology Co., Ltd.

• How can I install things in Linux with *no yum* and *no wget*?

  - by e9t

  I'm a newbie to Linux (that mainly uses Windows and Mac OS X) needing some advice. I was trying to install git on a Linux machine today, and encountered some problems: Not knowing the version of the installed OS, I've opened the /proc/version file which said: Linux version 2.6.9-42.0.2.ELsmp ([email protected]) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)) #1 SMP Thu Aug 17 17:57:31 EDT 2006 Then, as written in the git documents (http://git-scm.com/download/linux), I assumed I could use the yum install git command for Fedora, but got the following result. [root@myserver ~]# yum install git -bash: yum: command not found So I tried installing yum using wget, but wasn't so lucky. [root@myserver ~]# wget http://linux.duke.edu/projects/yum/download/2.0/yum-2.0.7.tar.gz -bash: wget: command not found I googled and found this page and this page, so tried installing yum with rpm, but only got a result full of question marks. (Possibly an encoding problem, hmm...) [root@myserver ~]# rpm -Uvh http://www.eomy.net/linux/install-yum-x86_64/wget-1.10.2-0.40E.x86_64.rpm http://www.eomy.net/linux/install-yum-x86_64/wget-1.10.2-0.40E.x86_64.rpm(??)?? ?????? ?: /var/tmp/rpm-xfer.TbuAOu: V3 DSA signature: NOKEY, key ID 443e1821 ???.. ########################################### [100%] wget-1.10.2-0.40E U???????g??????? wget-1.10.2-0.40E???? ??g??/usr/bin/wget ?? wget-1.10.2-0.40E U?????? ???? wget-1.10.2-0.40E???? ??g??/usr/share/man/man1/wget.1.gz ?? wget-1.10.2-0.40E U?????? ???? [root@myserver ~]# Finally, when I typed rpm --version in the terminal, I got the below results. [root@myserver ~]# rpm --version RPM ???? - 4.3.3 I would like to know what I can do or possibly try now. Is it not possible to wget or yum anything in my situation? Or is there any magical tool like homebrew (http://mxcl.github.com/homebrew/) that I can use? Any comments or advice would be appreciated. Thanks in advance!

• How to diagnose repeated "Starting up database '<dbname>'"

  - by Richard Slater

  I have a SQL 2008 server which is predominantly used as a development server, in the last two weeks it has been having occasional "fits", I have isolated the cause of these fits as CHECKDB being run almost continuiously, the following log information is logged to the Windows Event Log (Source: MSSQLSERVER, Category: Server): Event: 1073758961, Message: Starting up database 'DBName1'. Event: 1073758961, Message: Starting up database 'DBName2'. Event: 1073759397, Message: CHECKDB for database 'DBName1' finished without errors on 2010-07-19 20:29:26.993 (local time). This is an informational message only; no user action is required. Event: 1073759397, Message: CHECKDB for database 'DBName1' finished without errors on 2010-07-19 20:29:26.993 (local time). This is an informational message only; no user action is required. This is repeated every 1-2 seconds untill SQL Server is restarted or the offending databases are detatched. I initially thought that it was a problem with the databases so I took a backup and restored them to a SQL Express instance, all of the data is in tact, and CHECKDB runs without problem. The two databases that were causing a problem last week were not being used; so I took full backups of them and detached the databases, this resolved the problem. However at 0100 GMT this morning to other totally unrelated databases started showing the same problems. There is nothing in the event log to suggest that something happened to the server such as a restart, there are no messages about processes crashing or issues being detected with the storage controller. Speaking to the owner of the company this computer has suffered from "gremlins" in the past, however advice was taken and the motherboard was replaced and the computer rebuilt, memory and processor are the same. Stats: O/S: Windows 2008 Standard Build 6002 CPU: 2x Pentium Dual-Core E5200 @ 2.5GHz RAM: 2GB SQL: 2008 Standard 10.0.2531 Edit: someone posted then deleted a comment about AutoClose, it was turned on on the databases affected. It seems that best practice is to disable it so I have done that with the folllowing. EXECUTE sp_MSforeachdb 'IF (''?'' NOT IN (''master'', ''tempdb'', ''msdb'', ''model'')) EXECUTE (''ALTER DATABASE [?] SET AUTO_CLOSE OFF WITH NO_WAIT'')' I won't know if the problem recurs for some time so I am still open to further answers.

• Double MySQL Running on Mountain Lion

  - by Norris

  After I've done a full restart, my Apache PHP server doesn't connect to Local MySQL ( connecting via 127.0.0.1 because localhost for some reason fails always ). So I did this today: ? ~ mysqladmin shutdown -u root -p Enter password: ? ~ mysqladmin shutdown -u root -p Enter password: mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)' Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists! Which basically means that I succeeded in shutting down mysql. But as soon as I did - Apache PHP successfully connect to MySQL and my local sites work without a hiccup until the next restart. Here are a few other details: (as you can tell - I've installed MySQL via brew) ? ~ sudo ps aux | grep mysql N 4774 0.0 0.0 2432768 620 s000 S+ 9:53AM 0:00.00 grep mysql N 4772 0.0 2.6 3030168 440688 ??

• Moving windows-2003 hdd into virtual machine - with HDD shrink

  - by jm666

  Before you vote to close as exact duplicate, please read the full question. I was already read: Can I make a virtual machine out of a Windows XP physical machine? Disk2vhd,convert my PC to Hyper-V Virtual Machine Creating a Windows Virtual PC image from a Physical machine physical machine to virtual machine and place into VirtualBox BSOD trying to migrate Windows XP from a physical to a virtual machine http://en.wikipedia.org/wiki/Physical-to-Virtual and all other similiar questions here and several external sites too Unfortunately, don't find answer for my problem. I have an physical machine with 500GB HDD, on what is installed old Windows-2003 server with one server application. The application is like the windows itself, too old, no support for it today, haven't installation media and so on.. ;( On the HDD it is used only approx. 100MB (maybe less when will delete all unnecessary files). Want convert the the machine into the VirtualBox, and the VirtualBox should run on the same machine. Is possible to do this with the next steps? I can attach another HDD (via USB or internally) Boot an live Linux from CD, mount HDDs Run "something" on the Linux (the above wikipedia article have many pointer for the SW) for the conversion and store the image on the USB HDD - unfortunately, many of tools uses some specialty what exists in Windows-XP and above. No informations about Windows-2003 server, so what is an working solution for Windows-2003? try boot the virtual image with VirtualBox when it will run ok, remove the old installation, install Linux on the old 500GB hdd, copy the image and run.. The above should works (i hope), but the problems: i currently have only 320GB external USB hdd. (ofc, i can remove it from a box and enter it as internal HDD too) so, for the conversion I looking for the on the fly HDD shrink, so while moving the physical 500GB HDD need shrink it into smaller HDD - as i told above, only 100MB is used Exists something for this? (free) - or the only way is buying and larger 1TB hdd and using it for the conversion? Another question are: is anybody have real experience with windows-2003 conversion into VirtualBox? Looking for an answer from someone who really doing it and can figure out real pitfalls. (googling can do myself). exists here better approach for the solution?

• Django + gunicorn + virtualenv + Supervisord issue

  - by Florian Le Goff

  Dear all, I have a strange issue with my virtualenv + gunicorn setup, only when gunicorn is launched via supervisord. I do realize that it may very well be an issue with my supervisord and I would appreciate any feedback on a better place to ask for help... In a nutshell : when I run gunicorn from my user shell, inside my virtualenv, everything is working flawlessly. I'm able to access all the views of my Django project. When gunicorn is launched by supervisord at the system startup, everything is OK. But, if I have to kill the gunicorn_django processes, or if I perform a supervisord restart, once that gunicorn_django has relaunched, every request is answered with a weird Traceback : (...)

• Windows Vista: Networking can only connect "local only"

  - by Damien

  I am attempting to debug a problem on a Windows Vista laptop - not mine! Until just recently (last week or so), it was operating normally for about 4 years :) The problem is that I am having issues connecting to the local network (a basic wireless home router; more later) and the internet (via ADSL). This is both for wired [Broadcom chipset] and wireless [Intel chipset]. I will elaborate further later. To detail the network. I have three other clients (HTC phone, Ubuntu 12.04 desktop [wired] and Ubuntu 10.04 laptop [wireless]), all of whom are able to connect to the network and internet normally. A windows 7 virtual machine running on said desktop connects normally. I have tried two different wireless routers - Netgear DG834G and Netgear DGN3500. The same error mode is common to both. Updating the firmware to the latest on both routers does not help. Overall, it seems safe to say it's localised to the laptop in question. I do not have another Vista client to test with. The specific symptoms are as follows: When "connected", it says "Local Only", and says it cannot connect to the internet. This is true for both wired and wireless. It can get an IP address (192.168.0.5), and the router (192.168.0.1) reports that it can see the device. When I try to ping, I get the following results: ping 192.168.0.1 - (router) all packets lost ping 192.168.0.5 - (laptop's address) OK ping 192.168.0.4 - (desktop) all packets lost Pinging from the desktop to the problematic laptop results in "From 192.168.0.4 icmp_seq=1 Destination Host Unreachable" The most promising "fix" from trawling forums is KB928233 which does not work for me. The problem is persistent across reports (both full shutdown and hibernate) so it appears not to be sleep related. I am not a regular vista user, though I can fumble my way about a bit. Is there any other suggestions as to what I should do? Is there any further information I can provide?

• So I want to separate my Program Files from the hard disk with the other system files. What is the b

  - by grg-n-sox

  So I am running Windows 7 as my only OS. I have two hard drives on my computer. The first one is a 74GB Western Digital 10K RPM Raptor. The second one is a 1TB Seagate Barracuda (couldn't remember if it was a 7200.12 or some other decimal after the 7200). The OS in installed to the Raptor and I am just using the Barracuda for storage. With this setup, in case you couldn't guess already, the Raptor fills up quick and I am constantly having to maintain file locations. And although it is nice to have that quicker boot time and program loading, the time spent maintaining the drive makes me waste more time overall. So I am looking for a way to try to keep it clear while still keeping up system loading speeds. A performance hit on games and such is easily acceptable and as long as I can guarantee a 5GB space on the Raptor, I can always just temporarily move the disc image there. So I am figuring that having games installed like Boarderlands and Mass Effect, as well as having large files such as linux distro DVD disc images in My Documents, I probably should be moving my personal files and Program Files directories to the Barracuda. I currently have folders on the Barracuda for this, but this means routinely copying files over and I can't really do anything with the Program Files folder that already exists. The best I can do is remember to designate the install directory of any program installation to the alternative install directory, which I can't seem to get to ever work right with Steam. With that in mind, is there a way that is not too drastic to let me just change some folders and system settings once and everything works fine afterwards for my setup? I have considered just reinstalling Windows 7 to the Barracuda but that would defeat the purpose of the Raptor except for running disc images off of. I am also heard a bit about being able to use symlinks to fix this, but I have also heard that symlinks in Windows are not necessarily the same and not as well supported on Windows. An example a friend mentioned was something about how if you have a symlink in Windows on a small hard drive to a large hard drive and the contents the symlink points to is larger than the small hard drive's capacity, then Windows will think the smaller hard drive is full. So is there a fix/workaround that will let me use symlinks across hard drives without the issues or is there a better solution I am not being told about, not mentioning, or not thinking of?

• Access denied to mysql cause by invalid server hostname bind address

  - by Mark

  I cannot login to mysql using the terminal. [root@fst mysql]# mysql -h localhost -u admin -p Enter password: ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES) I am sure I have the correct password. The mysql is also running when I check status. The mysql database is also present in the directory /var/lib/mysql/. The host host.myi, host.myd and host.frm are present. By the way this a related to question on my previous problem MySQL server quit without updating PID file . Initially the problem arise when the root directory was full. To be able to login to directadmin and start mysql, I added a soft link of the /var/lib/mysql/ to /home/mysql. Since my database used up the most of the root directory. The root directory has 50Gb and /home has 1.5Gb. Somehow the /var/lib/mysql/idbdata1 is corrupted. So I move it to another location. Now, I can start the mysql server but I cannot login into it. Below are the contents from the myql logs. 121212 20:44:10 mysqld_safe mysqld from pid file /var/lib/mysql/fst.srv.net.pid ended 121212 20:44:10 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 121212 20:44:10 [Note] Plugin 'FEDERATED' is disabled. 121212 20:44:10 InnoDB: The InnoDB memory heap is disabled 121212 20:44:10 InnoDB: Mutexes and rw_locks use GCC atomic builtins 121212 20:44:10 InnoDB: Compressed tables use zlib 1.2.3 121212 20:44:10 InnoDB: Using Linux native AIO 121212 20:44:10 InnoDB: Initializing buffer pool, size = 128.0M 121212 20:44:10 InnoDB: Completed initialization of buffer pool 121212 20:44:10 InnoDB: highest supported file format is Barracuda. 121212 20:44:11 InnoDB: Waiting for the background threads to start 121212 20:44:12 InnoDB: 1.1.8 started; log sequence number 1595675 121212 20:44:12 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306 121212 20:44:12 [Note] - '0.0.0.0' resolves to '0.0.0.0'; 121212 20:44:12 [Note] Server socket created on IP: '0.0.0.0'. 121212 20:44:12 [Note] Event Scheduler: Loaded 0 events 121212 20:44:12 [Note] /usr/sbin/mysqld: ready for connections.

• How to install 32-bit libraries using Debian Testing

  - by bgoodr

  Question: What is the way to determine, ahead of time and without doing a full install of 64-bit Debian Testing NETINST, when Debian Testing has 32-bit libraries available and fully working and installable so that the following command works without broken package errors?: apt-get install ia32-libs ia32-libs-gtk The errors that occur when 32-bit libraries are not available, still in some broken state, or whatever is broken are detailed below. I already have concluded that "Just install Stable" is my stop-gap measure for now, but I would like to know the answer to the above question so as to avoid a lengthy installation process only to run into these problems at the very end. Details: I downloaded the 64-bit Debian Testing netinst a couple of days ago. This was "Jessie" built 20131014-06:07 via http://tinyurl.com/lejpa. This is weekly testing build. Yes, I know I should expect problems, and I did. I managed to get it completely installed and was able to invoke into GNOME, but not get past the 32-bit library problem. The problems starts when I attempt to install the 32-bit libraries via: apt-get install ia32-libs ia32-libs-gtk that returns: root@breath:~# apt-get install ia32-libs ia32-libs-gtk Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-i386 but it is not installable ia32-libs-gtk : Depends: ia32-libs-i386 but it is not installable Depends: ia32-libs-gtk-i386 but it is not installable E: Unable to correct problems, you have held broken packages. I then found an old (2012 is old to me) answer at ia32-libs : Depends: ia32-libs-i386 but it is not installable and even tried what they suggested there which was dpkg --add-architecture i386 apt-get update After executing the above, I tried again but got: root@breath:~# apt-get install ia32-libs ia32-libs-gtk Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-i386 ia32-libs-gtk : Depends: ia32-libs-i386 E: Unable to correct problems, you have held broken packages. root@breath:~# And then tried this: root@breath:~# dpkg --get-selections | grep hold And that returned nothing. Not only is there broken packages, the system doesn't even know what packages are broken, so Debian Stable is my only solution I know of right now. Hence my question above.

• Deleting windows.edb and unchecking Indexing service lead to hard drive file records swapping

  - by linni

  I followed the instructions listed here:http://www.mydigitallife.info/2007/09/18/turn-off-and-disable-search-indexing-service-in-windows-xp/ to free up space on hard drive by deleting the windows.edb indexing file... I also stopped windows search service as mentioned in the comments following the article. In addition to unchecking the "Allow Indexing Service to index this disk for fast file searching" check box on the properties dialog for the C:\ drive, I did the same for two usb connected hard drives (J:\ and I:\ ). I'm not sure why I did that, thought it might shrink the windows.edb file so I wouldn't have to delete it (which sounded a bit risky in my ears at the time). The file of course didn't shrink so I ended up deleting it and freeing up over 3 GB of space, yeehaw. However, as soon as I had done this I could not access the usb connected hard drives anymore. The error I got was "I:\photos is not accessible" "The file or directory is corrupted and unreadable" when I tried to open the photos directory on I:\ Here is where I enter the twilight zone... I try disconnecting I:\ usb hard drive. But XP shows me that instead J:\ drive has disconnected and I:\ is still there. So I disconnect both drives and restart the computer. I then connect one drive, but it lists up the contents of the other drive on root level. I tried connecting the drives vice versa and the same thing happens. I try taking one of the hard drives to another computer and when I connect it there it lists up not its own contents but the contents of the other hard drive and gives the same error as above when I try and access any of the folders (even folders on the root that have the same name as folders on the other drive (e.g. J:\photos and I:\photos)??? And no, this is not a me mixing up my drive letters. Computer Manager - Disk management shows the same result as explorer: The drive size is correct (one is 500GB, the other is 640GB) but the drive name is of the opposite drive, as long as the contents. Also, one drive was full of data and the other almost empty but they incorrectly show their free space status of the other drive. Somehow the usb drives seem to have switched file tables, file records, boot records or something, extremely weird! Even weirder, if I try and create a text file or folder on this drive, it works fine, accessing them, saving, whatever, all good, but accessing any other data on the drive gives me an error. Does anyone have a clue what is going on and more importantly, how I can restore the correct folder listings to access my family photos ??? cheers, linni

• Forward all traffic through an ssh tunnel

  - by Eamorr

  I hope someone can follow this and I'll explain as best I can. I'm trying to forward all traffic from port 6999 on x.x.x.224, through an ssh tunnel, and onto port 7000 on x.x.x.218. Here is some ASCII art: |browser|-----|Squid on x.x.x.224|------|ssh tunnel|------<satellite link>-----|Squid on x.x.x.218|-----|www| 3128 6999 7000 80 When I remove the ssh tunnel, everything works fine. The idea is to turn off encryption on the ssh tunnel (to save bandwidth) and turn on maximum compression (to save more bandwidth). This is because it's a satellite link. Here's the ssh tunnel I've been using: ssh -C -f -C -o CompressionLevel=9 -o Cipher=none [email protected] -L 7000:172.16.1.224:6999 -N The trouble is, I don't know how to get data from Squid on x.x.x.224 into the ssh tunnel? Am I going about this the wrong way? Should I create an ssh tunnel on x.x.x.218? I use iptables to stop squid on x.x.x.224 from reading port 80, but to feed from port 6999 instead (i.e. via the ssh tunnel). Do I need another iptables rule? Any comments greatly appreciated. Many thanks in advance, Regarding Eduardo Ivanec's question, here is a netstat -i any port 7000 -nn dump from x.x.x.218: 14:42:15.386462 IP 172.16.1.224.40006 > 172.16.1.218.7000: Flags [S], seq 2804513708, win 14600, options [mss 1460,sackOK,TS val 86702647 ecr 0,nop,wscale 4], length 0 14:42:15.386690 IP 172.16.1.218.7000 > 172.16.1.224.40006: Flags [R.], seq 0, ack 2804513709, win 0, length 0 Update 2: When I run the second command, I get the following error in my browser: ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://109.123.109.205/index.php Zero Sized Reply Squid did not receive any data for this request.

• How to run Django 1.3/1.4 on uWSGI on nginx on EC2 (Apache2 works)

  - by Tadeck

  I am posting a question on behalf of my administrator. Basically he wants to set up Django app (made on Django 1.3, but will be moving to Django 1.4, so it should not really matter which one of these two will work, I hope) on WSGI on nginx, installed on Amazon EC2. The app runs correctly when Django's development server is used (with ./manage.py runserver 0.0.0.0:8080 for example), also Apache works correctly. The only problem is with nginx and it looks there is something else wrong with nginx / WSGI or Django configuration. His description is as follows: Server has been configured according to many tutorials, but unfortunately Nginx and uWSGI still do not work with application. ProjectName.py: import os, sys, wsgi os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ProjectName.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application() I run uWSGI by comand: uwsgi -x /etc/uwsgi/apps-enabled/projectname.xml XML file: <uwsgi> <chdir>/home/projectname</chdir> <pythonpath>/usr/local/lib/python2.7</pythonpath> <socket>127.0.0.1:8001</socket> <daemonize>/var/log/uwsgi/proJectname.log</daemonize> <processes>1</processes> <uid>33</uid> <gid>33</gid> <enable-threads/> <master/> <vacuum/> <harakiri>120</harakiri> <max-requests>5000</max-requests> <vhost/> </uwsgi> In logs from uWSGI: *** no app loaded. going in full dynamic mode *** In logs from Nginx: XXX.com [pid: XXX|app: -1|req: -1/1] XXX.XXX.XXX.XXX () {48 vars in 989 bytes} [Date] GET / => generated 46 bytes in 77 m secs (HTTP/1.1 500) 2 headers in 63 bytes (0 switches on core 0) added /usr/lib/python2.7/ to pythonpath.

• configure squid3 to set up a web proxy in ubuntu12.04

  - by Gnijuohz

  I am in a LAN and have to use a proxy given to access the web in a very limited way. I can't even use google, github.com or SE sites. However I can use ssh to log into a server, which I have root access so basically I can do anything I want with it. So I was thinking that maybe I could use that server as a proxy so I can visit sites through it. I tested it using ssh -vT [email protected] which gave a proper response. And In my computer I can't do this. Also I tried downloading something from the gun.org using wget, which can't be done in my computer too. And it succeeded on that server. I don't know if that's enough to say that this server have full access to the Internet. But I assumed so and I installed squid3 on it. After trying some while, I failed to get it working.

• Stop squid caching 302 and 307 with deny_info

  - by 0xception

  TLDR: 302, 307 and Error pages are being cached. Need to force a refresh of the content. Long version: I've setup a very minimal squid instance running on a gateway which shouldn't not cache ANYTHING but needs to be solely used as a domain based web filter. I'm using another application which redirects un-authenticated users to the proxy which then uses the deny_info option redirects any non-whitelisted request to the login page. After the user has authenticated the firewall rule gets placed so they no longer get sent to the proxy. The problem is that when a user hits a website (xkcd.com) they are unauthenticated so they get redirected via the firewall: iptables -A unknown-user -t nat -p tcp --dport 80 -j REDIRECT --to-port 39135 to the proxy at this point squid redirects the user to the login page using a 302 (i've also tried 307, and i've also make sure the headers are set to no-cache and/or no-store for Cache-Control and Pragma). Then when the user logs into the system they get firewall rule which no longer directs them to the squid proxy. But if they go to xkcd.com again they will have the original redirection page cached and will once again get the login page. Any idea how to force these redirects to NOT be cached by the browser? Perhaps this is a problem w/ the browsers and not squid, but not sure how to get around it. Full squid config below. # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 192.168.182.0/23 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl https port 443 acl http port 80 acl CONNECT method CONNECT # # Disable Cache # cache deny all via off negative_ttl 0 seconds refresh_all_ims on #error_default_language en # Allow manager access only from localhost http_access allow manager localhost http_access deny manager # Deny access to anything other then http http_access deny !http # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !https visible_hostname gate.ovatn.net # Disable memory pooling memory_pools off # Never use neigh cache objects for cgi-bin scripts hierarchy_stoplist cgi-bin ? # # URL rewrite Test Settings # #acl whitelist dstdomain "/etc/squid/domains-pre.lst" #url_rewrite_program /usr/lib/squid/redirector #url_rewrite_access allow !whitelist #url_rewrite_children 5 startup=0 idle=1 concurrency=0 #http_access allow all # # Deny Info Error Test # acl whitelist dstdomain "/etc/squid/domains-pre.lst" deny_info http://login.domain.com/ whitelist #deny_info ERR_ACCESS_DENIED whitelist http_access deny !whitelist http_access allow whitelist http_port 39135 transparent ## Debug Values access_log /var/log/squid/access-pre.log cache_log /var/log/squid/cache-pre.log # Production Values #access_log /dev/null #cache_log /dev/null # Set PID file pid_filename /var/run/gatekeeper-pre.pid SOLUTION: I believe I might have found a solution to this. After days and days trying to figure it out, only through a random stumble I found client_persistent_connections off server_persistent_connections off This did the trick. So it wasn't so much cache as it was a single persistent connection messing things up. W000T!

• where on disk is space allocated for new files inside LVM lv with ext4 file system?

  - by Jost

  I run a multi-disk server with LVM2. Several large disks serve as LVM2 physical volumes for one volume group, containing one logical volume formatted with ext4. Nothing fancy, just your standard linear setup. Recently an additional, very small disk was added as physical volume to that volume group and I expanded both the logical volume, and the ext4 file system therein onto that disk. This lv is used to store incremental backups using rsync and is only about 30% full, there have rarely been any files deleted from it, only incremental writes. Now this new HDD I added to the pre-existing volume group has unexpectedly died on me, and the volume group won't come up because it is missing one physical volume. As fate will have it, this WAS the "in an event of catastrophic failure on the primary server"-backup, the event happened, the boss is not happy, so this kinda has to work... According to this (Part 3): http://www.novell.com/coolsolutions/appnote/19386.html it is possible to trick LVM into starting anyway by creating a new pv with identical metadata to the failed disk, which will make the volume accessible, but of course leave giant holes in the file system. I have'n tried it yet, because it involves repairing (writing to) the file system which eliminates the possibility of trying other things if it fails. Now my question is: How does this setup actually allocate disk space for new data? Is it allocated linearly from beginning to end of PVs, in the order they were added to the vg? Is it striped somehow in order to increase performance/balance load? since this defective disk was added only later to an existing lvm2 vg and lv, containing a half-empty ext4, what are the chances that there was never any data written to the defective disk? In other words: what are the chances of recovering all my data, even without the defective disk, by just starting the volume group as-is? Am I about to go spend $1500 on having 250GB of empty space recovered when I send the defective disk in for repair? Is there a way to check without mounting the file system and opening the files, hoping they contain something other than zeros? (comparing addresses of used data blocks inside ext4 to address ranges that were on the missing pv, something like that, preferably easy to automate) I know bitwise-copying the entire lv into an image file before trying to repair the ext4 would probably be a good idea, but since this lv is very large and I just suffered major file system failure on several systems it is probably a luxury I don't have... Any suggestions?

• Secure ldap problem

  Hi there, I have tried to config my openldap to have secure connection by using openssl on Debian5. By the way, I got trouble during the below command. ldap:/etc/ldap# slapd -h 'ldap:// ldaps://' -d1 >>> slap_listener(ldaps://) connection_get(15): got connid=7 connection_read(15): checking for input on id=7 connection_get(15): got connid=7 connection_read(15): checking for input on id=7 connection_get(15): got connid=7 connection_read(15): checking for input on id=7 connection_get(15): got connid=7 connection_read(15): checking for input on id=7 connection_read(15): unable to get TLS client DN, error=49 id=7 connection_get(15): got connid=7 connection_read(15): checking for input on id=7 ber_get_next ber_get_next on fd 15 failed errno=0 (Success) connection_closing: readying conn=7 sd=15 for close connection_close: conn=7 sd=15 Then I have search for "unable to get TLS client DN, error=49 id=7" but it seems no where has a good solution to this yet.

• Windows Media Player Object with Video_TS Files - No Sound Anymore

  - by user1624184

  I copied a bunch of my DVDs (yes, owned) to a drive and created a basic webpage to be able to search and play them. I am using the code at the bottom to create a Windows Media Player object and then play the video. The video files are pulled off the DVD in the original format so each movie has files like this: VTS_01_0.BUP VTS_01_0.IFO VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB VTS_01_4.VOB VTS_01_5.VOB VTS_01_6.VOB This all worked great until just recently. On my dev machine, I can play the videos but now, all of a sudden, there is no sound. I have tried the following but no luck: The video is not muted and the sound is at 50% Under the sound icon, under mixer, I checked IE and it is fine Sound works fine using another program, says WinAmp Opening Windows Media Player directly from the Start Menu and then playing the same movie works fine and I get sound I ensured that the option in IE to play sound on websites is checked I can play sound on other people's websites where they have embedded WMP files I tried resetting all of the IE settings on the Advanced tab in IE I tried my website, with my code below on another computer, AND IT WORKS FINE! I tried copying the media files listed above from the computer that works fine to my dev computer and it still doesn't work. If I try using a ".wmv" file, the sound does work By the way, I am using Win7 with IE8. As you can see, this is driving me crazy! Why would it stop working on my one computer and the same code and files work fine on another computer? Any help would be greatly appreciated. <OBJECT id="mediaPlayer" width="640px" height="480px" style="position:absolute; left:0px; top:0px;" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" type="application/x-oleobject"> <PARAM NAME="URL" VALUE="E:\test\VIDEO_TS\VIDEO_TS.IFO" /> <PARAM NAME="SendPlayStateChangeEvents" VALUE="True"/> <PARAM NAME="AutoStart" VALUE="True"/> <PARAM NAME="uiMode" VALUE="full"/> <PARAM NAME="volume" VALUE="50" /> <PARAM NAME="PlayCount" VALUE="9999"/> <PARAM NAME="fullScreen" VALUE="true"/> <PARAM NAME="enableContextMenu" VALUE="true"/> </OBJECT>

• My server freezes within a few hours of logging out. Staying logged in keeps the server running

  - by HappyEngineer

  I have an Ubuntu Godaddy server I use to host mail and webapps. It started having problems a couple months ago. It would lock up and stop responding to anything. I couldn't ssh into it, so I'd have godaddy power cycle the server. I have never seen anything that looked suspicious in the var logs (although I'm no expert at reading them). An fsck turned up no problems. Godaddy replaced the ram, but found no hardware problems. I started logging the output from "top" to a log file and found that even that stops running when the server freezes. Now, here is the crazy part: It got so bad that it would actually go down every few hours, but then it stopped going down. I eventually realized I had left an ssh terminal logged into the machine running top. This seemed unlikely to be a reason, but after the server was up with no problems for a full week (remember, it had been going down after just a few hours), I disconnected from the ssh session. Lo and behold, within a few hours the server froze again! I had them power cycle again and then left another ssh session open with top. It has been going without problems for 8 days now. I told others about this and they hardly believe me. I simply can't imagine what is going on. I don't know what else to try other than to just get a new server and reinstall everything. Does anyone have any ideas about what I can look for to determine what the cause is? Is it possible there's some sort of exploit on the server which only runs if everyone is logged out of the system? EDIT: The power management gone haywire sounds plausible, so I've modified the /boot/grub/menu.lst to boot with acpi=off and apm=off. It appears to have prevented kacpid and kacpid_notify from being in the process list, so I assume I did that right. I've disconnected all my sessions from the server. I'll check later tonight to see if it's still up. If it goes down then I'll try the pinging process idea. EDIT: It went down again. It lasted about a day. I've had them reboot, so now I'll try running "nohup ping -i 5 google.com &" and then disconnect. If it goes down again I'll come back. Hopefully someone will have some more ideas.
