• Windows 7 hangs while loading desktop

  - by Joshua

  I am facing a weird problem. My computer hangs while loading the desktop, and only the background shows up; no icons or bars load. If I power the system on and off about 4-6 times, I may be able to use it normally. The desktop loads normally after rebooting or in safe mode; this only occurs when I start the system normally. I've tried several things to fix it, such as removing all start-up items, but it still doesn't solve the problem. What should I do? I found three major errors in Event Viewer: Source: Microsoft-Windows-DistributedCOM Level: Error DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server: {7D096C5F-AC08-4F1F-BEB7-5C22C517CE39} Source: Microsoft-Windows-DistributedCOM Level: Error DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server: {7D096C5F-AC08-4F1F-BEB7-5C22C517CE39} Source: Service Control Manager Level: Error The Network List Service service depends on the Network Location Awareness service which failed to start because of the following error: The dependency service or group failed to start.

• Running DNS locally for home network

  - by Roy Rico

  I have a small home network that just got larger ( New roommate, My existing roommate got a laptop (on top of her computer)j, my friends coming over with laptop, etc ). I'd like to run a local DNS server for lookups of my local network stuff (fileserver.local, windowsTV.local, machineA.local, machineB.local, appletv.local). I used to have a business line with a static IP, and run bind/named internally. However, now, I have a normal account. My ISP's DNS servers are constantly changing (for whatever reasons my ISP doesn't like to keep the same IP range for long). I need my local DNS to be automatically updated to use my ISP's DNS for external traffic, but be able to maintain an internal DNS server (getting to update the hosts file is being a hassle with every new machine on top of rebuilding existing machines with win7 or Ubuntu 9.04). Additionally, My ISP's DNS servers often crash or become unresponsive. Are there any open DNS servers that are reliable (i don't want to reconfig every day) that I could use as my primary, then if those fail, then use my ISP's? UPDATE: Also looking for each workstation to be able to use dhcp to connect, but instead of getting ISP dns servers, getting my internal one.... Thanks

• sg_map & lsscsi showing old storage version

  - by PratapSingh

  I am using SUN storage and recently upgraded/refreshed my ISCSI LUN storage. We have replicated old storage to new storage and attached to our servers. I can see at SUN storage side that storage is attached to server and also from server when I run the below command it prints the following output : iscsiadm -m session tcp: [1] 10.1.1.10:3260,2 iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd The above storage is SUN STORAGE 7420 But when I run sg_map or lsscsi command it prints different version: lsscsi disk SUN Sun Storage 7410 1.0 /dev/sda disk SUN Sun Storage 7410 1.0 /dev/sdb disk SUN Sun Storage 7410 1.0 /dev/sdc disk SUN Sun Storage 7410 1.0 /dev/sdd Output of ls on "/dev/disk/by-path/" ls -1 /dev/disk/by-path/ ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-0 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-0-part1 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-18 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-18-part1 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-2 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-2-part1 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-4 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-4-part1 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-6 ip-10.1.1.10:3260-iscsi-iqn.86-03.com.sun:02:afsfsf58-c56a-6ba8-a944-addd258687cd-lun-6-part1 I have rebooted server twice but still I am getting the same output as given above.

• PsExec and Remote Environment Variables, Logging, Etc.

  - by alharaka

  When I run PsExec on a remote computer, I always fall short of what I want. What I would like ideally in most situations is a) a log on an admin server where each individual log has the name of each the remote computer it was generated from (e.g. COMPNAME1.log, COMPNAME2.log, etc.) or b) a log file on each remote computer with whatever name I specify. When I try scenario (a), I use the following command. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username cmd /c echo TEST >> \\server.company.tld\share\%computername%.log Problem is that it never works. All the computers just write to the log where %computername% is just the computer I execute PsExec from in my office. What I want are unique logs for each computer specific in the listofcomputers.txt that will correctly use the hostname from the remote environment variable without issue. Is that even possible? It does not seem to work for me. I tried this, and the syntax is clearly wrong. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username "cmd /c echo TEST >> \\server.company.tld\share\%computername%.log" PsExec just fails saying the system file cannot be found (read: syntax fail). As for scenario (b), it appears to be a variation of a similar problem. When I run a command like this, it does not work. %SystemDrive%\path\to\psexec.exe @listofcomputers.txt -u DOMAIN\username "cmd /c echo %computername% >> \\server.company.tld\share\aggregated.log" Is there something I do not understand about remote path and environment variables with PsExec on the cmd.exe console (I have not even tried the dreaded PowerShell yet). I know such things work in a batch file (cmd /c \\server.company.tld\share\runthis.bat), but is there a reason it will not work when executing commands as arguments? I always need this, and can never get it!

• Symantec Endpoint Protection Virus Definitions

  - by Gus Denton

  I have done some Googling but I cannot get a definitive answer certainly not from the Symantec KB. I have a Virtualised Win 2003R2 server 32bit. It has been provisioned to me with Symantec Endpoint Protection 11.0.62xxx CLIENT (not a definitions server) the directory C:\Program Files\Common Files\Symantec Shared\VirusDefs is 750MB IT doesn't contain .tmp directories so it is NOT a corrupt definitions server. IT does contain directories named with a date pattern YYYYMMDD.xxx Some of these folders are 12 months old and I would like to recover the space. The sysmantect forums are full of this stuff but a lot of the postings contain links back to documents that are not specific to End Point Protection Client. It appears that I should be able to delete the older folders and all will be OK. with a service restart however there is a warning about having Live Update Administrator Installed Firstly I have no idea if I have this installed how to I check and secondly can I just ditch these old files and restart ? Regards Gus Denton Learning and Teaching Uni of New South Wales Sydney Australia For those trying to assist me I thankyou. I have followed some instructions found on the Symantec site and assumed that the response from Nixphoe would resolve my issue. It appears that as I am on a provisioned VM from a central IT unit I cannot run the Symantec commands from the Run prompt as my admin creds to get me in. (smc -stop) Basically I need to claw back some Diskspace from the c: drive which is being filed up with WSUS patches and Symantec files. I have managed to delete one symantec cache through the live update control panel and recovered 470Mb I suppose my last question for those more experienced than myself is, can I simply remove say the two oldest virus definition folders without completely foobaring the End Point protection and the server ? Regards Gus

• Find and Replace several several different values all at once

  - by matt

  I have a file with multiple instances of Text_1 and Text1 and I need to replace both those strings with Text_A and TextB respectively. Currently I'm doing two Find and Replace functions on each file one that finds Text_1 and replaces it with Text_A and the other that finds Text1 and replaces it with TextB. Is there any way to do this all at once instead of having to run "Find and Replace" twice? I am using Dreamweaver CS3, but I also have Notepad++, regular Notepad, OO Writer, MS Word if those will be easier. Ideally I could do this in Dreamweaver or Notepad++ but I'm open to downloading something else to get the job done. I'd prefer not to have to do any command line stuff or create a batch file (while I'm aware of it, I don't understand it really). Edit: In case the above description isn't clear, let me explain it this way... I want to run Find & Replace 1 time in 1 document and I want it to do ALL of the following during that one Find & Replace instance: Find: Text_1 and Replace with: Text_A Find: Text1 and Replace with: TextB I am not trying to do a Find and Replace across several documents.

• Does the mysql Client API Library version have to match the installed MySQL/Percona server version?

  - by William Jamieson

  I'm running Scientific Linux 6.3 (binary compaible with Redhat/CentOS/etc..) as a LAMP stack. I've installed Percona server and client v5.5 from the Percona yum repository. However when I run phpinfo() I notice that under the MySQL and mysqli sections, it lists the Client API Library version as 5.1.66, and not 5.5x. I'm guessing these need to match, at least to major versions, and I have no idea what the possible consequences of such a mismatch could be. Do I need to revert to Percona server and client v5.1? This is for a production environment so it needs to be right. I'd appreciate any input or experience people could offer.

• Windows Server 2003 SBS domain in multiple sites

  - by E3 Group

  We have about 25 employees in our current office and are looking to open up another office in another capital city housing about 15 employees. In our current office, we are running a domain hosted by a 2003 SBS server and I've been tasked by the boss to expand our infrastructure to the new office in the cheapest way possible (cheapest way in the short run that is, because my boss doesn't think more than 6 months ahead). So I'm looking to get a second hand server and have it run Server 2003 Std with exchange server 2003. These are the things that it needs to do: Replicate shared folders that are hosted in the parent LAN. Deliver emails hosted in the parent Exchange Server Somehow link up with the parent domain controller and push the AD to the remote site I'm pretty sure 3 is impossible but the DC would be available if a VPN connection is present, right? On that note, would I be looking at hardware VPN connections? I'm not sure how to deploy the new site as this is my first time doing it and i'm making it especially difficult for myself, seeing as the AD and DC is on an SBS server. Would I first start by establishing a VPN connection and then joining the new server to the domain? Will things 'just work' if I install exchange onto the new server and point outlooks to it? and how would I be able to replicate shared folders?

• How Do I Secure WordPress Blogs Against Elemento_pcx Exploit?

  - by Volomike

  I have a client who has several WordPress 2.9.2 blogs that he hosts. They are getting a deface kind of hack with the Elemento_pcx exploit somehow. It drops these files in the root folder of the blog: -rw-r--r-- 1 userx userx 1459 Apr 16 04:25 default.htm -rw-r--r-- 1 userx userx 1459 Apr 16 04:25 default.php -rw-r--r-- 1 userx userx 1459 Apr 16 04:25 index.asp -rw-r--r-- 1 userx userx 1459 Apr 16 04:25 index.aspx -rw-r--r-- 1 userx userx 1459 Apr 16 04:25 index.htm -rw-r--r-- 1 userx userx 1459 Apr 16 04:25 index.html -rwxr-xr-x 1 userx userx 1459 Apr 16 04:25 index.php* It overwrites index.php. A keyword inside each file is "Elemento_pcx". It shows a white fist with a black background and the phrase "HACKED" in bold letters above it. We cannot determine how it gets in to do what it does. The wp-admin password isn't hard, but it's also not very easy either. I'll change it up a little to show you what the password sort of looks like: wviking10. Do you think it's using an engine to crack the password? If so, how come our server logs aren't flooded with wp-admin requests as it runs down a random password list? The wp-content folder has no changes inside it, but is run as chmod 777 because wp-cache required it. Also, the wp-content/cache folder is run as chmod 777 too.

• Why is Xampp unable to start Apache?

  - by jribeiro

  I formatted my computer a week ago. Installed wampp on Windows XP, git and everything I needed. When I run git for the first time it told me it had a problem with my user folder (because of the accents) so I created a new user and migrated everything to the new one. After this, wampp wouldn't start anymore. I uninstalled it and installed xampp which is what I'm using now. My problem is that even though I requesed xampp to install Apache as a service it isn't installed. It doesn't show in Windows' services screen. Xampp control panel shows mysql service running OK. When I click to install Apache as a service it returns no error. When I click Start Apache no error is outputed. No file and no errors under c:/xampp/apache/log/ If I restart my computer it says that Apache service is not installed. I tried to reinstall wampp and the same problem occurs. If I run netstat -a -no nothing is running on port 80! What can I do?

• Networkmapping script (VBS) Vista doesn't work, XP does

  - by The_cobra666

  Hi all, I've got a weird problem, (like always :p ) Okay: Situation: Windows 2003 domain with XP clients. With a GPO I'm running a VBS script on login to map a few drives. This works great on XP, but not on Vista. If I manually run the script after the user has logged on, it works. So I know the script works on Vista, it just doesn't run via the GPO. The user has admin privileges. I also have the same problem on Windows 7 RC1. So it must be related. The script: on error resume next Dim objNetwork Dim strDriveLetter, strRemotePath, strUserName strDriveLetter = "Z:" strRemotePath = "\\Onsgeluk.ons_geluk.local\Profieldoc" Set objNetwork = WScript.CreateObject("WScript.Network") strUserName = objNetwork.UserName objNetwork.RemoveNetworkDrive "Z:" objNetwork.MapNetworkDrive strDriveLetter, strRemotePath _ & "\" & strUserName objNetwork.RemoveNetworkDrive "X:" objNetwork.MapNetworkDrive "X:" , "\\Onsgeluk.ons_geluk.local\Data" objNetwork.RemoveNetworkDrive "Y:" objNetwork.MapNetworkDrive "Y:" , "\\Onsgeluk.ons_geluk.local\Mappen\hoofdverpleging" Does anyone have a clue? Thanks in advance guys (and girls) ps: sorry for my bad english!

• Running Windows Update inside Windowx XP Mode

  - by Noam Gal

  I am working on a Win 7 Ultimate machine, and was using XP for some development tasks (for compatibility checks). Everything worked like a charm on the XP, including updates. Two days ago I had to switch computer (mainly a new motherboard/cpu), and I had just stuck my old HD inside the newer case. Win 7 worked like a charm - installed all the new drivers, identified everything automatically, no sweat. The trouble started when I tried running my old XP mode - it won't launch, complaining about the cpu change. I figured it's not a big deal, and I deleted the VM, and re-ran XP mode. It told me it can't find it, and offered to create a new one, just what I wanted. I had finished setting up the new XP mode VM, and it seems to work just fine. Got it to use the host network adapter, so I can surf from "inside". But I can't get Windows Update to run. Whenever I click on the "Custom" button on the WU site, after a short while, I get the [Error number: 0x80072EFD] page. I tried several solution from around the web for it (clearing some cache and restarting the wuauserv, even a microsoft fix-it run), but still nothing seems to work. Anyone here has any new tip for me? Thanks.

• Boinc permissions problem on OS X

  - by Erik Vold

  I installed boinc 6.10.21 on my OS X 10.5 in order to upgrade from a 6.6 version that I was running today, and I am the admin user, and I was logged in as the admin user. As I was installing 6.10.21 I was asked if non admin users should be allowed to use Boinc, and I said 'yes' to this. Then when I tried to open Boinc I got a message like the following: "You currently are not authorized to manage the client. Either re-install and allow non-admin users or contact your administrator to add you to the 'boinc_master' user group." So I tried to reinstall first, and I was not asked if non admin users should be allowed to use Boinc.. so I retried a few times and got no different result.. So I downloaded 6.10.43 and installed that, and again I was not asked if non admin users should be allowed to use boinc.. and when I tried to run Boinc I got the same message like: "You currently are not authorized to manage the client. Either re-install and allow non-admin users or contact your administrator to add you to the 'boinc_master' user group." So I did a Google search trying to figure out how to add my admin user to the bonic_master user group and found this which suggested I run the following in terminal: "sudo dscl . -append /Groups/boinc_master GroupMembership <your user's short name> CR" So I did this and now I get the following error: BOINC ownership or permissions are not set properly; please reinstall BOINC (Error code -1200) So I reinstall and I am ever asked the question about allowing non admin users again, and I still get this error message every after every reinstall attempt.. What should I do?..

• Conky starts above windows in Ubuntu Maverick

  - by DesertIvy

  Hey guys, I did not run into this problem until I upgraded my Ubuntu box to Maverick Meerkat (10.10). Basically, whenever I start my computer, conky runs as expected, except it gets drawn over any windows that I load (see screenshot). To fix this for a single session, I simply restart conky by running killall conky; conky in a terminal. Conky gets re-drawn below active windows (namely, only appearing on my desktop), and does not have the border/drop-shadow, but I have to do this every time I start a new session. Is there a simple way to fix this? I have a small shell script that I run on startup, but it does not seem to solve the problem. #!/bin/bash sleep 10 && conky; sleep 5 && killall conky; conky; Below is the non-text part of my .conkyrc file. # Conky settings # background yes update_interval 1 cpu_avg_samples 2 net_avg_samples 2 override_utf8_locale yes double_buffer yes no_buffers yes text_buffer_size 2048 #imlib_cache_size 0 temperature_unit fahrenheit # Window specifications # own_window yes own_window_type override own_window_transparent yes own_window_hints undecorate,sticky,skip_taskbar,skip_pager,below border_inner_margin 0 border_outer_margin 0 minimum_size 200 250 maximum_width 200 alignment tr gap_x 220 gap_y 280 # Graphics settings # draw_shades no draw_outline no draw_borders no draw_graph_borders no # Text settings # use_xft yes xftfont caviar dreams:size=8 xftalpha 0.5 uppercase no temperature_unit celsius default_color FFFFFF # Lua Load # lua_load ~/.lua/scripts/clock_rings.lua lua_draw_hook_pre clock_rings

• Why should one have a secondary DNS server?

  - by Sam Levin

  I'm very confused. I basically understand how DNS works. Here's an example that helps illustrate what I'm having trouble understanding. Right now, I run a small web-server. I use my provider's DNS manager, so I don't have a DNS server hosted on the machine. Let's say for a second, that I don't use my host's DNS, and I decide to set up a DNS server on my server. Hypothetical scenario: my server (entire) server goes down - DNS included. Why do I need backup DNS? If the server is down, who cares if the DNS server is down too, considering that even if I had DNS up (it wasn't on the crashed server), it wouldn't be able to forward requests anyway since the server would be down? Is the point of having secondary DNS, to be able to change the IP addresses that your DNS server points to, so if your webserver was down, you could redirect traffic to a backup? How would you switch to the secondary provider, in the event that your main DNS provider becomes unavailable? Is a backup DNS system basically up all the time? How is it configured? Is it just an exact clone of the DNS server you would have on your server? Do they run simultaneously? Hopefully someone can see what I'm hung up on, and provide some guidance. Thanks

• how to properly set environment variables

  - by avorum

  I've recently started using Windows (having used Ubuntu up until now) and I find myself unable to properly set environment variables. Whenever I set them they don't seem to work. I've been going to Start-Edit Environment Variables for your Account and editing the PATH value in the upper half of the GUI. Here's what I've got so far. ;C:\Chocolatey\bin;C:\tools\mysql\current\bin;C:\Program Files (x86)\Git\bin;C:\Program Files\MySQL\MySQL Server 5.6\bin\;C:\Python33\Scripts; These are each the parent directories of the executables I'd like to be able to run by name from CMD, but mysql, git, and pip aren't being recognized. Am I doing something wrong syntactically or at a general understanding level? I'd like to be able to run these commands without having to specify the full path to the executables every time. EDIT: The full PATH extracted from CMD PATH=C:\Python33\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\Java\jre7\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft SDKs\TypeScript\;C:\Program Files (x86)\MySQL\MySQL Utilities 1.3.4\; ;C:\Chocolatey\bin;C:\tools\mysql\current\bin I'm being forced to use Windows by my work environment, I don't enjoy the state of affairs.

• Cooling for a small server room

  - by John Zwinck

  I have a server room about 12 feet square with an unfinished ceiling (exposed ducts and wiring). It houses a few servers (about ten, 1U and 2U) and some networking gear (four 1U switches, three routers, three modems, two cable boxes). With the door closed, it runs around 80 degrees Fahrenheit with half the servers turned on. When I turned on all the servers it reached 86 before I chickened out and propped the door open. The room is adjacent to air-conditioned office space, but does not itself have dedicated air conditioning. The ventilation for this room seems to be limited to one duct coming in at ceiling level, with a powered fan to draw air in, and one duct at ceiling level to allow air to flow out (it seems like it may just go into the drop ceiling cavity in the adjacent room). The adjacent office space stays fairly cool, but I'd prefer not to leave the door propped open all the time. There is both 110v and 208v service in the room, and plenty of power available. But there are no windows, and no floor drains (in a pinch we might be able to run a condensation hose through a small hole we'd drill in the wall to a nearby sink area, but only if absolutely necessary). I've considered portable A/C units, but I'm not sure on sizing and a lot less sure how we would run the exhaust hose(s). I suppose we could point one at the existing room exhaust duct (air return), but substantially modifying the duct is probably a no-no. I've also considered installing a fan box in the door of the room, but I'm concerned that this will only drop the temperature a little. Even right now, with all the equipment on, the room is at 83 degrees with the door open. And the main building A/C turns off daily at 6 PM to conserve energy, so the adjacent room temperature rises at night. How would you cool this room? Let's say the goal is to bring the temperature with everything running from a steady state of around 90 degrees down to 75 (equivalently, to offset the heat produced by ten 1U servers).

• A tiered approach to cloning linux partitons

  - by Djurdjura

  I'm looking at a strategy for cloning Linux (root) partitions without having to use a Live CD. Literature suggests rightly that the source and target partitions must be umounted to be able to get a clean clone. This assumes that you need to use a LiveCD. I was wondering if instead of requiring a LiveCD, if using a 3rd partition that would emulate the LiveCD functionality, if we can't achieve the same functionality. In other words, at a high level a system with 3 partitions (all bootable): Rescue Partition (LiveCD emulation) Running Partition (Source) Backup Partition (Destination) All 3 partitions are LVMS. When it's time to clone the source partition to the backup (destination) partition, we would boot to the rescue partition, unmount the other 2 partitions (is it required?), run disk check on the source, copy to the destination (dd or simple copy to avoid replicating the defragmentation from the source), run disk check on the destination partition, update Grub menu list to force boot from either partition, and reboot into that partition. My question, is it an approach that you'd recommend? MBR in all this? Any gotchas or extra checks required? Thanks, D. PS. On recommendation from members, posting here instead of stackoverflow.com.

• Caused by: java.net.SocketException: Software caused connection abort: socket write error

  - by jrishere

  I running JSP on Oracle 11g, Weblogic 10.3.4. I have 2 managed server and a oracle admin server installed. I am encountering an error where intermittently the log file of the 2 managed server and admin server will show java.net.SocketException: Software caused connection abort: socket write error. The application can run for 2 days without showing this error or it can show up a few times in a day. The server load are similar everday. When this error is been encountered, the server will just stop accepting connections and will not be able to access the application. Even if I try to access the application through localhost, I will not be able to access the JSP pages and a 503 http status is shown but then I am able to access the static HTML page. I will not be able to access the Oracle 11g Weblogic admin console page. When I take a look at admin server log, it shows that the managed servers are disconnected from the admin server and vice versa. Magically the application is able to recover by its own and the application is able to access again or I need to restart the server as restarting the service of the application does not work. The FTP connections that the application is connected to are closed as well. I am able to ping to telnet to the server port. The event log doesn't seem to be leaving any information. We did run wireshark to see the packet traffic and it seems that the application port is sending a RST, ACK packet to the load balancer. Any kind help will greatly be appreciated. Should you need more info, feel free to ask me. Thanks in advance.

• GNU screen multiuser mode is broken in OS X 10.6 (Snow Leopard)

  - by schustafa

  I'm using GNU screen for remote pair programming. Let's call the local account for the remote user 'pairpair'. I have the following lines in my .screenrc: multiuser on acladd pairpair I have run sudo chmod u+s /usr/bin/screen. However, when the remote user tries to connect to my screen with the command screen -r [my_account_name]/[pid_of_screen] I receive the following message: Attach attempt with bad pid(xxx) The pid listed in the error message matches the pid of the screen process run by the remote user. The remote user's screen process hangs; my screen session continues happily along after the error message disappears. I've tried using both the built-in screen (at /usr/bin/screen) and the screen available from MacPorts, but I get the same error in both cases. This worked on OS X 10.5 (Leopard). I've googled around for the error message, but most of the hits relate to some BSD bug from 2003 or so (which was fixed). Has anyone else seen this behavior? Does anyone have any idea how to make multiuser support in screen work in SL?

• Automated software installation for MS Windows?

  - by Duncan Bayne

  I am currently setting up a Windows development environment (the whole Visual Studio 2010 stack plus plugins on top of Windows 7). This has got me wondering whether there's a Windows equivalent to what I do for dev environment setup in Ubuntu. It takes literally hours to get a dev environment set up in Windows, involving a lot of manual intervention. On Ubuntu, I have two shell scripts - one I run as root which configures the system using apt-get (amongst other things), one I run as me which configures my user account. Those scripts live in my private Subversion repository. To set up a dev environment from scratch requires five commands: sudo apt-get install -y subversion svn co http://svn.XXXX.XXX/personal/ cd personal sudo ./ubuntu_setup_root.sh ./ubuntu_setup_user.sh The only human intervention required is to pick a root password for MySQL. So it takes only a few minutes of human attention to go from a vanilla Ubuntu installation to a full development environment with the latest builds of everything, perfectly tailored down to shortcut keys and wallpaper. Is there an equivalent process for Windows? In an ideal world it'd be something trivially scriptable using C# Script or Powershell, which could live in source control & make use of a repository of ISOs downloaded from MSDN ...

• Cisco 7206 error trying to copy running-config (Bad file number)

  - by jasondewitt

  I have a cisco 7206 that terminates a bunch of pppoa sessions for dsl users. Today I noticed that if I tried to "show run" nothing happened. I mean that it doesn't show anything and just sends me right back to the command prompt. I decided I should probably try and back up the config and that is where I'm stuck. Any time I try to copy the running-config to tftp or to pcmcia card that I know is not full I get the following error: %Error opening system:/running-config (Bad file number) I get this error when I try to do anything with the running config. I've been googling around, but I haven't found any thing else that talks about this error. I've seen people say to erase the nvram and then try to "copy run start", but I don't want to erase the nvram until I can pull off a copy of the running-config. I would try to reboot it, but the startup-config that is on the nvram looks to be woefully out of date (good job me!). Any ideas what might be wrong? or how I can get the running config off the router?
