• Bad Mumble control channel performance in KVM guest

  - by aef

  I'm running a Mumble server (Murmur) on a Debian Wheezy Beta 4 KVM guest which runs on a Debian Wheezy Beta 4 KVM hypervisor. The guest machines are attached to a bridge device on the hypervisor system through Virtio network interfaces. The Hypervisor is attached to a 100Mbit/s uplink and does IP-routing between the guest machines and the remaining Internet. In this setup we're experiencing a clearly recognizable lag between double-clicking a channel in the client and the channel joining action happening. This happens with a lot of different clients between 1.2.3 and 1.2.4 on Linux and Windows systems. Voice quality and latency seems to be completely unaffected by this. Most of the times the client's information dialog states a 16ms latency for both the voice and control channel. The deviation for the control channels mostly is a lot higher than the one of the voice channels. In some situations the control channel is displayed with a 100ms ping and about 1000 deviation. It seems the TCP performance is a problem here. We had no problems on an earlier setup which was in principle quite like the new one. We used Debian Lenny based Xen hypervisor and a soft-virtualised guest machine instead and an earlier version of the Mumble 1.2.3 series. The current murmurd --version says: 1.2.3-349-g315b5f5-2.1

• Cannot access site via IP / hostname

  - by DaveB

  I am renting a VPS with Debian installed running JBoss AS6 for my web app. I recently had some problems with my DNS hosts as they messed up the A-records for my domain which caused some new A-records to be added by mistake The DNS problem is now sorted and the domain is working ok, however I noticed that the web server no longer responds via direct IP or hostname in a web browser (although it pings ok and I can SSH in using the hostname ok) Is there any explanation for this? I am using rinetd to forward traffic from 80 to port 8080 but thats been ok for a while Any suggestions would be appreciated Regards

• Disallow everything in directory except subdirectories with certain name using .htaccess or vhost.conf

  - by Jizbo Jonez

  How can I disallow everything in a directory except any subdirectories that have a certain name using htaccess or even vhost.conf for the site? I have a protected main directory which contains subdirectories. Each of the subdirectories have another child dir named 'thumbs', that I want to allow people access to. In the thumbs folder I have files which all start with 'thumb_' prefix for the filename. So which approach to use, .htaccess FilesMatch or vhost DirectoryMatch? and what would be the code to use? Thanks

• Nginx + PHP-FPM executes script, but returns 404

  - by MorfiusX

  I am using Nginx + PHP-FPM to run a Wordpress based site. I have a URL that should return dynamically generated JSON data for use with the DataTables jQuery plugin. The data is returned properly, but with a return code of 404. I think this is a Nginx config issue, but I haven't been able to figure out why. The script 'getTable.php' works properly on the production version of the site which is currently using Apache. Anyone know how I can get this to work on Nginx?

• Can't access newly created Subversion repos

  - by Jean-François G. B.

  Sorry in advance, I'm pretty new in server configuration. So I followed this tutorial to install Subversion on my CentOS server. I'm at the part I should test the URL to make sure I can access it and that it's password protected, but it's not working, I can't access it. What is wrong? Is there some config missing? I don't know what more details to give, but if you need some, please ask! :) Thanks in advance.

• Request Tracker 4: Ticket Escalation

  - by Randy

  I am running Request Tracker 4 on a Debian Squeeze Server. I have to implement a priority escalation. Actually escalation is not the right term for this since the the ticket priority should be set linear via rt-crontool (or any other tool that can be run via a cronjob) dependent on the time that has been passed between the „Started“ and „Due“ to a number between 0 (starting priority) and the „Final Priority“ (eg. 100) while the value of the „Final Priority“ should be reached exactly the moment the „Due“-Date is passed. This already implies that the search condition should be all tickets of a certain queue that have „Started“ AND „Due“ AND „Final Priority“. The cronjob should be called very frequently for excample any 5 or 10 minutes so that the call should be indempotent and not depentent on the frequency of the rt-crontool invocations. One Example: A Ticket is Started at 2012-12-23 0am and Due is 2012-12-23 11.59pm while the Final Priority is 100. When the call is made at noon the priority should be set to 50. Could anybody help me with this? Thank you for reading this to the bottom!

• CPU Configuration Issue for 2 Servers (Server 2008 R2)

  - by Bill Moreland

  I have 2 servers running the exact same Classic ASP code with Access DBs (yes, not ideal, but it is what it is, for now). 1) Xeon 5520 @ 2.27 GHz (6 GB Memory) 2) Xeon E5-2620 @ 2.00 GHz (2 processors, 32 GB Memory) For most pages the newer E5-2620 processes the pages between 10-15% faster. On pages requiring heavy and/or multiple complicated access stored procedures (queries) the older 5520 does a much better job. I believe the servers are configured nearly identically. My question: is it possible that the newer, multi-processor server is not as good at handling Classic ASP as the older single processor? Is there a configuration difference that needs to be in place that I'm missing since I'm shooting for identical implementations?

• Multiple VLANs on a single subnet

  - by mstaessen

  I would like to establish the setup shown below. The image is taken from (http://gcharriere.com/blog/?p=620) and explains how to set this up on a brocade device. I would like to use an ubuntu server to do the routing. Right now, the switch and the server/router are connected with a trunk and the server uses the vlan package, kernel module and (inner) subnets for routing. I would like that: no IP addresses get lost in the subnetting (outer subnet is /26, inner subnets are /28) I don't want the rigorous subdivision of my outer subnet. I want to assign a VLAN to any IP in the outer subnet. How do I need to configure my interfaces? What is the "ubuntu" translation of "ip follow ve"? Thanks!

• How broken is routing strategy that causes a martian packet (so far only) during tracepath?

  - by lkraav

  I believe I've achieved a table that routes packets from and to eth1/192.168.3.x through 192.168.3.1, and packets from and to eth0/192.168.1.x through 192.168.1.1 (helpful source). Question: when doing tracepath from 192.168.3.20 (from within vserver), I'm getting kernel: [318535.927489] martian source 192.168.3.20 from 212.47.223.33, on dev eth0 at or near the target IP, while intermediary hops go without (log below). I don't understand why this packet is arriving on eth0, instead of eth1, even after reading this: Note that you may see packets from non-routable IP addresses when running the traceroute or tracepath commands. While packets cannot be routed to these routers, packets sent between 2 routers only need to know the address of the next hop within the local networks, which could be a non-routable address. Can someone explain that paragraph in human language? Based on short initial trials so far, everything else seems to work without causing martians. Is this contained to the nature of tracepath operation or do I have some other bigger routing problem that will cause work traffic breakage? Side note: is it possible to inspect martian packet with tcpdump or wireshark or anything of the sort? I'm have not been able to get it to show up on my own. vserver-20 / # tracepath -n 212.47.223.33 1: 192.168.3.2 0.064ms pmtu 1500 1: 192.168.3.1 1.076ms 1: 192.168.3.1 1.259ms 2: 90.191.8.2 1.908ms 3: 90.190.134.194 2.595ms 4: 194.126.123.94 2.136ms asymm 5 5: 195.250.170.22 2.266ms asymm 6 6: 212.47.201.86 2.390ms asymm 7 7: no reply 8: no reply 9: no reply ^C Host routing: $ sudo ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: sit0: <NOARP> mtu 1480 qdisc noop state DOWN link/sit 0.0.0.0 brd 0.0.0.0 3: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:24:1d:de:b3:5d brd ff:ff:ff:ff:ff:ff inet 192.168.1.2/24 scope global eth0 4: eth1: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:46:46:a3:6a brd ff:ff:ff:ff:ff:ff inet 192.168.3.2/27 scope global eth1 inet 192.168.3.20/27 brd 192.168.3.31 scope global secondary eth1 # linux-vserver instance $ sudo ip route default via 192.168.1.1 dev eth0 metric 3 unreachable 127.0.0.0/8 scope host 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.2 192.168.3.0/27 dev eth1 proto kernel scope link src 192.168.3.2 $ sudo ip rule 0: from all lookup local 32764: from all to 192.168.3.0/27 lookup dmz 32765: from 192.168.3.0/27 lookup dmz 32766: from all lookup main 32767: from all lookup default $ sudo ip route show table dmz default via 192.168.3.1 dev eth1 metric 4 192.168.3.0/27 dev eth1 scope link metric 4 Gateway routing # ip route 10.24.0.2 dev tun0 proto kernel scope link src 10.24.0.1 10.24.0.0/24 via 10.24.0.2 dev tun0 192.168.3.0/24 dev br-dmz proto kernel scope link src 192.168.3.1 192.168.1.0/24 dev br-lan proto kernel scope link src 192.168.1.1 $ISP_NET/23 dev eth0.1 proto kernel scope link src $WAN_IP default via $ISP_GW dev eth0.1 Additional background Options for non-virtualized network interface isolation?

• "log on as a batch job" user rights removed by what GPO?

  - by LarsH

  I am not much of a server administrator, but get my feet wet when I have to. Right now I'm running some COTS software on a Windows 2008 Server machine. The software installer creates a few user accounts for running its processes, and then gives those users the right to "log on as a batch job". Every so often (e.g. yesterday at 2:52pm and this morning at 7:50am), those rights disappear. The software then stops working. I can verify that the user rights are gone by using secedit /export /cfg e:\temp\uraExp.inf /areas USER_RIGHTS and I have a script that does this every 30 seconds and logs the results with a timestamp, so I know when the rights disappear. What I see from the export is that in the "good" state, i.e. after I install the software and it's working correctly, the line for SeBatchLogonRight from the secedit export includes the user accounts created by the software. But every few hours (sometimes more), those user accounts are removed from that line. The same thing can be seen by using the GUI tool Local Security Policy > Security Settings > Local Policies > User Rights Assignment > Log on as a batch job: in the "good" state, that policy includes the needed user accounts, and in the bad state, the policy does not. Based on the above-mentioned logging script and the timestamps at which the user rights are being removed, I can see clearly that some GPOs are causing the change. The GPO Operational log shows GPOs being processed at exactly the right times. E.g.: Starting Registry Extension Processing. List of applicable GPOs: (Changes were detected.) Local Group Policy I have run GPOs on demand using gpupdate /force, and was able to verify that this caused the User Rights to be removed. We have looked over local group policies till our eyes are crossed, trying to figure out which one might be stripping these User Rights to "log on as a batch job." We have not configured any local group policies on this machine, that we know of; so is there a default local group policy that might typically do such a thing? Are there typical domain policies that would do this? I have been working with our IT staff colleagues to troubleshoot the problem, but none of them are really GPO experts... They wear many hats, and they do what they need to do in order to keep most things running. Any suggestions would be greatly appreciated!

• Xen HVM guest has severe clock drift

  - by ipartola

  I am seeing a very severe clock drift on my Xen HVM VPS, rented from a hosting provider, so I don't have access to the dom0 system. I continuously run ntpd, but the clock drifts by as much as 30 seconds in 5 minutes and NTP cannot keep up. Has anyone experienced this? Here are some details: $ dmesg | grep clock [ 0.160000] Measured 347 cycles TSC warp between CPUs, turning off TSC clock. [ 0.396000] * this clock source is slow.

• PHP+AJAX with MySQL - Query every 2 seconds, too many in TIME_WAIT

  - by Ryan

  I have a basic HTML file, using jQuery's ajax, that is connecting to my polling.php script every 2 seconds. The polling.php simply connections to mysql, checks for ID's newer than my hidden, stored current ID, and then echo's if there is anything new. Since the javascript is connecting every 2 seconds, I am getting thousands of connections in TIME_WAIT, just for my client. This is because my script is re-connecting to MySQL over and over again. I have tried mysql_pconnect but it didn't help any. Is there any way I can get PHP to open 1 connection, and continue to query using it? Instead of reconnecting every single time and making all these TIME_WAIT connections. Unsure what to do here to make this work properly.

• How to increase acpiphp slots?

  - by Eil

  Oh RHEL 5.5, there are 31 ACPI PCI hotplug slots by default: acpiphp: Slot [1] registered ... acpiphp: Slot [31] registered Is there a way to increase this number? I haven't been able to find an argument to supply to modprobe, or a sysctl knob to tweak, but I know there must be ways to get more slots based on some Google sleuthing. (For the curious, this is just preliminary experimentation to see how many virtual disks I can hot-add to a running KVM guest.)

• Linux Server Performance Monitoring

  - by Jon

  I'm looking to monitor performance on my Linux servers (which happen to be Centos). What are the best tools for monitoring things in realtime such as: Disk Performance I/O, swapping etc.. CPU Performance Looking for low level tools, rather than web based tools such as Nagios, Ganglia etc... n.b. I'd like to know exactly what each tool does rather than just having a list of random toolnames if possible please. Why the tool is a better option than others would be good also.

• How to continue an HTTrack mirroring session from the command line?

  - by isme

  I want to drive my mirroring project using the Command Prompt instead of the WinHTTrack interface so that I can script and schedule the mirroring session more easily. The output of httrack --help gives a simple command for continuing an interrupted mirroring session: example: httrack --continue continues a mirror in the current folder When I try httrack --continue in my HTTrack project folder, all I get is output like this: Example: -%F "<!-- Mirrored from %s by HTTrack Website Copier/3.x [XR&CO'2010], %s -->" * Option %F needs to be followed by a blank space, and a footer string With each parameter on a new line for readability, the first line of my doit.log file looks like this: -qiC1%P0s0b0u1j0%s%u0N0%I0p1DaK0c1T30H0%kf2E1800A25000%c0.1%f#f -F "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" -%F "" -%l "en, en, *" http://saa.gov.uk/search.php?SEARCHED=1&SEARCH_TABLE=council_tax&SEARCH_TERM=City+of+Edinburgh&DISPLAY_COUNT=100 -O1 "C:\\Users\\Iain\\Projects\\Council Tax Analysis\\Code\\HTTrack\\Council Tax Valuation List" -* \ +*search.php?SEARCHED=1* -*DISPLAY_MODE=FULL* The parameter %F "" should tell HTTrack to use an empty footer. I used the WinHTTrack interface to create the project and start the mirroring session. I can interrupt and continue the mirroring session using the interface. The HTML files saved by WinHTTrack have no footer.

• DVI monitor detected only on computer startup

  - by kamil

  I've recently connected a new monitor, LG M2252D-PZ, to a rather outdated computer with Windows XP and Radeon 9600. XP has SP3 installed, video drivers are the latest version back from the times the video card was still supported. My problem is that the monitor works fine only as long as I don't turn it off or switch it to a different input. When I turn it back on, it says "no signal". The key to the problem must be the DVI port, to which the new monitor is connected. The previous monitor was connected to the VGA output, and I've tested that the new one also works fine when connected to the analogue port. Apparently, the computer tests for the presence of a monitor on the DVI port only on startup. The question is, how do I change this?

• Formatting a truecrypt volume on windows: Truecrypt failed to obtain administrator privileges

  - by daveh551

  Following shaneselman's advice (http://www.hanselman.com/blog/TheComputerBackupRuleOfThree.aspx), I'm setting up a 2TB external drive as a backup, and encrypting it using TrueCrypt. This is under Windows 7. (I've used TrueCrypt before, but not since XP days.) I installed TrueCrypt with default options. After taking 23 hours to format the 2TB container, it finishes with an error saying "TrueCrypt cannot obtain administrator privileges." When I click OK on that, it says it can't format the container as NTFS, do I want to format it as FAT, and I don't so I click No, and it exits with nothing to show for 23 hours of compute time. So I set the "Run as administrator flag" on the TrueCrypt shortcut, and try again. This time, when I go to format the contain (prepared to wait ANOTHER 23 hours), it pops up a dialog saying you're formatting this as administrator. "The volume may be created with permissions that will not allow you to write to the volume when it is mounted. If you want to avoid that, close this instance of Volume Creation Wizard and launch a new one without administrator privileges." Great - I can either run as non-administrator, and it will fail to create the volume at all, or I can run as administrator and create a volume I can't write to. I think I'm doing something wrong, but it's not clear to me what. Any help?

• MS Excel - splitting a formula into individual cells?

  - by Nick

  I'm not sure if this is possible, or if I'll have to do it manually, but I have lots of cells in the following format: =87.12+56.52-16.50+98.21-9.51 If possible, I'd like to break it up into columns, like so: I have a data in excel in the format: 87.12 | 56.52 | -16.50 | 98.21 | -9.51 I've tried text to columns based on the '+' symbol, but it falls short when I then try to break it down by the '-' symbol, it moves into columns as appropriate, it removes the minus from the start of the figure Any suggestions would be very welcome! Thank you

• how to check if something is in the queue of torque?

  - by kloop

  I want to re-run some jobs that completed prematurely under torque. These jobs are run through .job scripts (using qsub). However, I don't want to re-run a job which is already in the queue. Given a script filename, how can I know whether it is already in torque's queue (using qstat?) or not? I prefer to do it programmatically, of course, so any oneliner that searches for a given script name would be great. I will note that I can grep submit_args in qstat -f, but I can't get it to display the whole script name when it is too long. This is crucial. EDIT: I managed to solve it using the following command: qstat -x | perl -pi -e 's/\<\//\n/g' | grep job$ | grep -v submit_args | perl -pi -e 's/Job_Id\>\<Job_Name\>//' works because all my scripts end in the string "job".

• Networking not working in Windows 7 - "The account specified for this service is different from the account specified for other services"

  - by tog22

  I have a homebuilt computer with a GA-Z68MA-D2H-B3 motherboard with a Realtek RTL8111E LAN chip. Ethernet was working fine in Windows 7 until I reinstalled this OS, but now it's stopped, while still working in other OSes. I've tried reinstalling drivers from both the Gigabyte and Realtek sites to no avail; I've also plugged in and installed an Asus USB-N13 wifi dongle and this doesn't work oddly. How can I diagnose and fix this issue? In 'Network and Sharing Center' says "The account specified for this service is different from the account specified for other services running in the same process" under the heading 'Unknown'. Following the advice at http://www.sevenforums.com/network-sharing/130159-dependency-service-group-failed-start.html#post1122627 I've gone to 'Control Panel= Admin Tools= Services' and ensured the services listed at that URL are started (one - IIRC 'Come+ Event System' refused to start as user 'Local services' so I've had to set it to log on with the 'Local system account'... I suspect this may be part of the problem).

  I have a network camera that is only able to give me an image, not a video stream. In my home network this image is at http://192.168.1.16/loginfree.jpg I'm able to get this image a few times per second. I would now like to be able to serve it up as a video stream so I can use it in zoneminder. Any idea as to how I do that? I've messed around with named pipes and ffmpeg's image2pipe, but I can't get it to work properly.

• Best console based text editor not only for programmers [closed]

  - by robo

  I need console based text editor for writing both source codes and human readable texts such as emails. I need it to be user friendly. It mean for me: You can use it the same way as the notepad or gedit. You can use mouse there. If you need your mother of girlfriend or somebody to edit your text they will know what to do, they will not realize it is a console and will have only a feeling it is something like a notepad. copy, paste, undo works as usual with usual key combinations (Ctrl-C, Ctrl-V, Ctrl-Z). shift and arrows works as usual. They select the text. And when I return to the computer I want to use the text editor for programming. I expect: Syntax highliting auto indenting replacing spaces with tabs keyboard shortcuts for compiling possibility to configure it to use a debugger autocompletions for c#, java, c++ and other languages other things I expect from IDE's. I was working and configuring vim for a few years. But It never fulfilled all of my expectations (but it almost did). I thing I could get vim configured perfectly if I had few more weeks time for configurating it. Unfortunately I cannot afford to be configuring vim forever. Is there other alternative? Hopefully some editor I once set up and it will works forever? What do you use? I often hear people are using emacs. Is it worth learning?
