• Is there a way to batch create DNS slave zones on a new slave DNS server?

  - by Josh

  I currently have a DNS server which is serving as a master DNS server for a number of our domains. I want to set up a brand new secondary DNS server. Is there any way I can automatically have BIND on the new server act as a secondary for all the domains on the primary server? In case it matters, I have Webmin on the primary server. I believe Webmin has an option to create a zone as a secondary on another server when creating a new master zone on one server, but I don;t know of any way to batch create secondary zones for a number of existing master zones. Maybe I'm missing something. Is there a way to "batch create" DNS slave zones on a brand new slave DNS server for all the DNS zones on an existing master?

• How to reset password for Dell PowerConnect 2708?

  - by oherrala

  I do as the user manual says and press "Managed Mode" button to get into unmanaged mode and then press "Managed Mode" button again for managed mode. This should reset the device to factory defaults and username "Admin" with no password. However, the device resets (I think) and I can access the web console from IP 192.168.2.1, but the username and password doesn't work. Maybe the device doesn't reset after all. Or the username/password has been changed in some firmware upgrade? What should I do to get into management of this switch?

• Tool to copy errortext in "Error on page" for Microsoft Internet Explorer.

  - by user25313

  Sometimes I see an "Error on page" icon in the lower left part of Internet Explorer (e.g. version 7.0). When I click on this icon a popup-box show some error information (I do not know if the error always is an javascript error or what to be called). The popup-box can not be resized and the text cannot be copied (e.g. for use in a error report). Does anyone knows how to retrieve the information so in can be copied and used elsewhere? Maybe someone has developed a tool to do that.

• How to open embedded Visio files with only Visio Viewer?

  - by Christopher Galpin

  For some bizarre reason Visio Viewer seems incapable of opening vsd files when they're embedded within a (2010) Excel document: However if I open the Excel document with 7-zip, browse to xl\embeddings, extract oleObject1.bin and rename it to a .vsd file extension it opens perfectly fine with Visio Viewer in Internet Explorer. Since this opens fine on a computer with the full Visio installed, my guess is it's trying to launch Visio rather than IE. Is there something I can do to fix this? I've been scanning with Process Monitor and searching with RegScanner comparing a Visio-installed system to a VisioViewer-installed system and there doesn't actually seem to be any sort of registry value giving direction here... maybe it's just the nature of OLE. (If it can't be fixed I'm okay with converting the extracted one to a .png or so to replace the embedded object, but the "solutions" I've found for vsd to image conversion are very poor or non-working, i.e. buggy code, code with Visio dependencies, or online services.)

• Web deploy (msdeploy), syncing everything but sites and pools (but include siteDefaults)

  - by jishi

  Today I do the following to sync two webservers but skip all site configuration: msdeploy -verb:sync -source:webServer -dest:webServer,computerName=web25:8080 -skip:objectName=section,absolutePath=system.applicationHost/sites -skip:objectName=section,absolutePath=system.applicationHost/applicationPools However, this effectively also skip the siteDefaults, which I do like to sync (system.applicationHost/sites/siteDefaults) There doesn't seem to be a way to "include" a section, to override the skip directive. And there doesn't seem to be a way to sync only the siteDefaults section from applicationHost either, since source appHostConfig only seem to sync a specified site, and not siteDefaults. Maybe it is possible to "skip" using an Xpath expression or similar, to only skip the nodes, but include , but I find the documentation a bit confusing and my Xpath is rusty.

• Strange Inode/Ram cache drops happening in CentOS

  - by FunkyChicken

  I run a CentOS 5.7 machine (64bit) with 24GB ram and 4x SAS drives in RAID10 setup. This machine runs nginx/1.0.10, php-fpm & xcache. About a month back the RAM usage of this machine has changed. About every few hours the 'CACHE' is flushed from the RAM, this happens exactly when the 'Inode table usage' drops. I'm pretty sure these drops are related. (see the 2 attached images). This server hosts quite a lot of small files (20M all a few KB big). Not many files are deleted (maybe 100 per hour (total size a few MB max)), not enough to account for the huge Inode table drops. I also have no crons running which could cause these drops. Sar -r output: http://pastebin.com/C4D0B79i My question: Why are these huge RAM/Inode usage drops happening? How can I get Nginx/PHP to use all of my servers RAM?

• fail2ban and denyhosts constantly ban me on Ubuntu

  - by Trey Parkman

  I just got an Ubuntu instance on Linode. To secure the SSH on it, I installed fail2ban (using apt-get), but then had a problem: fail2ban kept banning my IP (for limited durations, thankfully) even though I was entering the correct password. So I removed fail2ban and installed denyhosts instead. Same problem, but more severe: It seems like every time I SSH in, my IP gets banned. I remove it from /etc/hosts.deny, restart denyhosts and log in again, and my IP gets banned again. The only explanation I can think of is that I've been SSH-ing in as root (yes, yes, I know); maybe something is set somewhere that blocks anyone who SSH-es in as root, even if they log in successfully? This seems bizarre to me. Any ideas? (Whitelisting my IP is a temporary fix. I don't want to only be able to log on from one IP.)

• How to encrypt disk transparently without destroying data

  - by aseq

  On a Linux system, be it Debian, Redhat or any distro, I would like to encrypt the disk on the fly. That is, encrypt the disk transparently to the OS whilst it is running, reboots, shuts down etc. In addition it should not destroy data. I know there is (commercial) software for windows that does it. But I need a Linux solution. The solutions I know of do not support this as far as I can see (luks, truecrypt...). Maybe there is some hack or work around available?

• vim command palette, similar to sublime text

  - by user137369

  In sublime text, we can press ??P to bring up the command palette. Are there any similar tools for vim? I’ve been trying vim-ctrlp-cmdpalette, and although it works relatively well (there are some small issues), it depends on ctrlp (not a huge problem), and it looks like it won’t see much development (it has 14 commits over the course of 3 days, 5 months ago, for an “Initial experimental version”), so I was wondering if there are any known alternatives, since searching for “vim command palette” is a bit limiting; maybe there are some other terms more appropriate for this.

• Where Catalyst stores applist for switchable graphics?

  - by noober

  I cannot add an app to the list to manually set it to high performance (Radeon instead of Intel HD). When I browse for an exe, nothing happens, the list is still empty. So, maybe I can edit some .cfg or .ini? UPDATE This is NOT my screenshot... actually I've found it on the Net. The list with iexplore.exe is what I meant. When I click 'Browse' and choose any exe (Portal2.exe, for instance) nothing happens. The list is empty, so I cannot set mode for Portal2.exe.

• Why is VMware vSphere Client hanging at the console?

  - by David

  When I use the vSphere Client (against an ESXi 4.1 server) it hangs a lot. It's always at the same place - using the console on a VM. The console stops responding - and a lot of times, the management window stops responding as well. The operating system won't close the window (as the application isn't responding) and requires a force close. I've had the console refuse to give up the mouse, and have had the console freeze with the cursor in the top left (before any VM software starts, maybe?). The environment is this: the system is a Dell laptop running Ubuntu 10.10 (Maverick) fully updated with VirtualBox OSE running Windows XP (also fully updated). The vSphere Client is running in the Windows XP VM. Got all that? How do I keep these hangs from happening? It is very aggravating. I'm still trying just to get the VM loaded with Ubuntu Server...

• How do I get Bugzilla to authenticate with Active Directory LDAP?

  - by user65712

  After reading this guide and trying a ton of permutations based on that, is there an easy way to get Bugzilla working with an AD server? I keep getting the error: 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db0 I created an AD "bugzilla" user account with "Account Operators" permission as directed. I'm not sure if the error is saying that my login is incorrect or the system login to access LDAP is incorrect. Maybe I just missed an arcane option somewhere in the settings. You'd think all I'd need to do is specify the server name. As you might have been able to tell, I don't have a lot of LDAP experience. Also, will the Sysinternals LDAP tool help here?

• Good translation (manually) software

  - by S.Hoekstra

  I'm looking for a good translation software. i do not mean something that does all the translation automatically for me. But rather something that aids me in translating large pieces of text, since it has to be a perfect translation i can't leave it to computers alone. Something like http://translate.google.com/toolkit but with more options/functions would be great. Preferably freeware ofcourse (But paid is not a problem). At the moment i use the Google toolkit since it's adequate for now, but i really need something more advanced. But looking for such software on google etc. is really hard because of the confusion with translation services and things like babelfish. Do you know any software like this? and maybe want to share your thoughts/experiences.

• My PC becomes very slow after changing page file in XP.

  - by Jane

  Hello there, I have 5 partitions in my computer (C, D, E, F, G), and C: is the system partition. Recently I changed the page file setting to use 768-768 MB from the G:, without changing the C: default value (256-512 MB). Everything runs fine until I rebooted my PC. I unset the G:'s page file before I rebooted my PC. Well, after I rebooted my PC, my XP becomes VERY slow. damn slow. I don't know how long I wasted to wait for the boot screen to disappear. (Well, maybe about 1-3 mins. Normally it is under 10 secs) and when I tried to enter the desktop, it just like using a computer without a VGA card, or VGA driver installed. Very slow. Any suggestions to fix this problem? Because I hate to repair-install my XP =\ Thanks.

• My DNS cannot resolve an web site address?

  - by ipkiss

  Hello all, Recently, I could not access the webpage bbc.co.uk anymore, while I can access other websites smoothly. Ar first, I though there may be some problem with my laptop. However, if I use my laptop through my company network, I can load the page bbc.co.uk normally. Then, I though maybe my ADSL at home blocks that web address. However, I tried another laptop with my home ADSL and it can load the page bbc.co.uk very fast. Now I do not know what could be the problem. Can anyone tell me please? Thank you.

• squid running out of sockets

  - by drscroogemcduck

  I have a setup where squid sits in front of a java server and acts as a reverse proxy. Recently i've load tested the site and if i fire 100 threads at it each making a request using jmeter i start getting errors in my load test tool like 'no route to host' even though the load test tool and the server are on the same machine. if i run the following command where port 82 is the port my squid server is running on: netstat -ann | grep 82 | wc -l i get 22000 or something and most of them are in TIMED_WAIT. i'm thinking that maybe the huge number of sockets in the TIMED_WAIT state are starving the box of resources.

• nginx php-fpm uploaded files have nginx ownership after executing move uploaded file

  - by Vangel

  I have a problem with php 5.3.6 using PHP-FPM and file uploads. My Nginx runs as user nginx PHP-FPM uses pools configured for each vhost. For example a user: test group : test runs one pool. When the php file uploads to temp file it is owned by user test. After move_uploaded_file is executed by php script it is owned by nginx :/. The reason for this could be the fact that the original upload file script does an exec('/usr/bin/php do_uploadedfiles.php') which does the actual moving. I do not know if the change in ownership to web server is the correct behaviour. Is there a way in PHP to change the ownership back to the user I want? Maybe make exec "run as"?

• Transferring existing files from ext3 to ZFS (on FreeBSD)

  - by peppergrower

  I use an old machine as a file server, for backups, and as a testbed for development. I currently have Debian installed, but I'm very interested in FreeBSD because of ZFS: I really, really like its file integrity features. Before I switch, however, I wanted to ask: what's the best way to migrate my ~400GB of files from the current filesystem (ext3) to ZFS? My number-one requirement is that the migration be absolutely reliable: I don't want to lose any data. (I'll be backing it up before doing this anyway, but still.) My secondary goal is speed: I'd rather not have this take overnight if it doesn't have to. Recommendations? Is FUSE for FreeBSD stable enough to use? What about FreeBSD's native read support for ext3? NFS, maybe? How have you done this?

• How to keep Windows 7 from sleeping while scanning the PC.

  - by D Connors

  So, I've been using Microsoft Security Essentials lately. And it usually takes a couple hours or more for it to full scan my hard drive. Because of that, I commonly leave it scanning while I go do something else. Problem is: 10 minutes later, windows 7 goes to sleep, and the scan is (obviously) paused. That's What I'd like to stop happening. So far, the only way I've been able to avoid it was to create a power plan, and switch to it while away, to keep the PC from sleeping. Problem is that I have to keep switching power plans and I'd like the PC to be able to go to sleep in case MSE finishes scanning and I'm still not back. Maybe I'm just asking for too much, but I've been surprised by the users here plenty of times already. So let me know if you know how to keep the PC from sleeping while MSE is scanning. Thanks

• Redirect 'host-based' requests to a port (inside a docker container)

  - by Disco

  I'm trying to achieve this fun project of having multiple 'postfix/dovecot' instances inside a docker container. I'm searching for 'something' that would redirect any incoming request on port 25 (any maybe later 143, 993) to the right container on a different port. Here's the idea : +-------+ +----------+ (internet)----(port 25) |mainbox| ---- (port 52032) |container1| (postfix) +-------+ | +----------+ \ (port 52033) +----------+ |container2| (postfix) +----------+ So the idea is to 'redirect' requests coming to port 25 and based on 'hostname' to forward to the right port (internally); ideally, it would be great to manage this 'mapping' with a database/textfile Any ideas ? Directions ?

Need to do a citrix login via IE(amounts to loading a url) beause it wont run in google chrome 3. then set default browser to chrome Environment: Windows XP, no admin priv's no admin priv's mean I can't touch registry Basic Steps I'm Doing: In a bat file: 1.Set default browser to IE 2.run a citrix SSO login via IE (not compatible with chrome) 3.Set default browser to Chrome 4.kill IE 5.live long and prosper So i have it all running except "Set default browser to IE" I can set the default browser to chome by using portable chrome's cmd line argument --make-default-browser but I can't undo that process. If I launch IE, it pops up that 'make ie default browser' window which stops the SSO process. So If I can disable that check via bat file, that would also work for me.

• Commercial version of Freenet6

  - by grnbeagle

  I've been using Freenet6 from gogoNET to make my mobile device publicly accessible via IPv6. It works quite well except that the service is not as stable because it's non-commercial usage only as their servers are hosted for free by different operators around the world. Apparently gogoNET sells hardware called gogoSERVER which allows one to build a service similar to Freenet6. I've inquired their sales team, but they were unable to tell me which companies have a commercial, production-quality implementation of Freenet6. Specifically I'm looking for the following features in IPv6 service provider: Client-based IPv6 connectivity for mobile devices: gogoCLIENT (gw6c) is ideal for mobile devices since it allows a device to go online regardless of the device's location. API for account maintenance: so that we can create device accounts from our software Static IPv6 address: (or maybe I mean IPv4 address) by this I mean, just like gogoNET6 service (username.broker.freenet6.net), we want to provide our users with a permanent URL for their device Any info on commercial IPv6 service provider utilizing gogoSERVER is appreciated. Thanks.

• Is there a special way to set up Garry's Mod for Mac? [closed]

  - by credford

  I just downloaded Garry's Mod from Steam and every time I try to play Single Player on the first map, it crashes on the Loading Resources section of the progress bar. Here is some of the exception information the system prints out: Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x000000001acec4d0 Crashed Thread: 4 When I ran it on the Windows side (Bootcamp), Windows 7 required me to give Garry's Mod some permissions. I wasn't asked to do this on the Mac side. Maybe that's it? Is there some kind of special setup for the Mac?

• Renting linux server just to make backups of my personnal data ?

  - by Matthieu

  Hi all, I would like to be able to backup ALL my computers data on a Linux server. For now, I have a home server, but soon I will be travelling, without home (so no home server). I was thinking of renting a dedicated linux webserver, but this is expensive, and I don't need a fast machine "web-oriented" with mysql server and all, I just need a full SSH access (full control, and then I install my programs). Does "backup servers" exist ? Am I doing it wrong (maybe that is not a good solution) ? Note : I run Mac OS, Windows and Linux, I backup through rsync, I want full control on my backup, not an automated "magic" backup like MobileMe or anything like that. Edit : I need around 500Gb storage

• Access the failing addresses within bounce_message_file in exim

  - by mkurz

  We are running exim version 4.72 I'm using bounce_message_file to customize our bounce messages, like desribed in the documentation Within this bounce message template I can access various variables like $message_exim_id, etc. Is there also a way to access the list of the failing addresses (maybe with their error messages) in such a variable (as string, list,... whatever) or in any other way? It does not really matter how and in which format they are, I just want access them within the bounce message template file. (I am referencing to the failed addresses usually listed automatically after the line "This is a permanent error. The following address(es) failed:") Thank you very much for your help!
