• Server 2008 Disk Management Hangs

  - by Payson Welch

  So I have looked everywhere for the solution to this and have tried many things. There is one post on SE related to this and I tried the suggested answer but I am still having problems. We have a server running Server 2008 R2 Standard x64. I need to increase the space of C: since the free space is running very low. However when I open Server Manager and try to go to the "Disk Management" snap-in it just hangs. There is a status message on the bottom of the window that says "Connecting to Virtual Disk Service...". Here are the steps I have taken: Ran sfc /scannow Set all of the drives to be dirty and rebooted so that they would be scanned Executed chkdsk /f /r /b /v on all of the drives. Checked for Windows updates (none). Verified that the services "Virtual Disk", "RPC Procedures" and "Plug and Play" are all running. One symptom is that the service "Virtual Disk" does not cleanly shut down. I receive a message about the process being unexpectedly terminated when I try to stop or restart it. Also I cannot find anything relevant in the event logs. Any ideas or suggestions?

• Parsing the output of "uptime" with bash

  - by Keek

  I would like to save the output of the uptime command into a csv file in a Bash script. Since the uptime command has different output formats based on the time since the last reboot I came up with a pretty heavy solution based on case, but there is surely a more elegant way of doing this. uptime output: 8:58AM up 15:12, 1 user, load averages: 0.01, 0.02, 0.00 desired result: 15:12,1 user,0.00 0.02 0.00, current code: case "`uptime | wc -w | awk '{print $1}'`" in #Count the number of words in the uptime output 10) #e.g.: 8:16PM up 2:30, 1 user, load averages: 0.09, 0.05, 0.02 echo -n `uptime | awk '{ print $3 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $4,$5 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $8,$9,$10 }' | awk '{gsub ( ",","" ) ; print $0 }'`"," ;; 12) #e.g.: 1:41pm up 105 days, 21:46, 2 users, load average: 0.28, 0.28, 0.27 echo -n `uptime | awk '{ print $3,$4,$5 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $6,$7 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $10,$11,$12 }' | awk '{gsub ( ",","" ) ; print $0 }'`"," ;; 13) #e.g.: 12:55pm up 105 days, 21 hrs, 2 users, load average: 0.26, 0.26, 0.26 echo -n `uptime | awk '{ print $3,$4,$5,$6 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $7,$8 }' | awk '{gsub ( ",","" ) ; print $0 }'`","`uptime | awk '{ print $11,$12,$13 }' | awk '{gsub ( ",","" ) ; print $0 }'`"," ;; esac

• "A disk read error occurred" when booting XP disk image in VirtualBox

  - by intuited

  I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

• Upgrading Visio 2000 to Visio 2007

  - by dirtside

  I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

• Solaris: detect hotswap SATA disk insert

  - by growse

  What's the method used on Solaris to get the system to rescan for new disks that have been hot-plugged on a SATA controller? I've got an HP X1600 NAS which had 9 drives configred in a ZFS pool. I've added 3 disks, but the format command still only shows the original 9. When I plugged them in, I saw this: cpqary3: [ID 823470 kern.notice] NOTICE: Smart Array P212 Controller cpqary3: [ID 823470 kern.notice] Hot-plug drive inserted, Port=1I Box=1 Bay=12 cpqary3: [ID 479030 kern.notice] Configured Drive ? .......

NO But can't figure out how to get the format command to see them so I know they've been detected by the system.

• Can't successfully run Sharepoint Foundation 2010 first time configuration

  - by Robert Koritnik

  I'm trying to run the non-GUI version of configuration wizard using power shell because I would like to set config and admin database names. GUI wizard doesn't give you all possible options for configuration (but even though it doesn't do it either). I run this command: New-SPConfigurationDatabase -DatabaseName "Sharepoint2010Config" -DatabaseServer "developer.mydomain.pri" -AdministrationContentDatabaseName "Sharepoint2010Admin" -DatabaseCredentials (Get-Credential) -Passphrase (ConvertTo-SecureString "%h4r3p0int" -AsPlainText -Force) Of course all these are in the same line. I've broken them down into separate lines to make it easier to read. When I run this command I get this error: New-SPConfigurationDatabase : Cannot connect to database master at SQL server a t developer.mydomain.pri. The database might not exist, or the current user does not have permission to connect to it.

• upstart config to start sync daemon as non-root user

  - by Rudiger Wolf

  I am planning to use inosync to sync data from master server to several client servers. I have created a user called rsyncuser in both master and slaves with access permissions and passwordless ssh access from master to slave servers. Inosync is working when I use it from the command line as rsyncuser. Next I want this to start automatically when server is turned on. I figured upstart is the way to get this working. I am unable to find the right upstart command to get this working. Here is my upstart conf file. The problem seems to be around running "inosync -d -c /etc/inosync/inosync_rsyncuser.py" as a given user. As you can see I have tried a number of various options! description "start inosync to sync data to other CDN Servers as rsyncuser" console output #start on startup #stop on shutdown start on (net-device-up and local-filesystems) stop on runlevel [016] #start on runlevel [2345] #stop on runlevel [!2345] #kill timeout 30 env RUN_AS_USER=rsyncuser expect fork script echo "Inosync updtart job seems to have started" /tmp/upstart.log # exec sudo -u rsyncuser -c "ls -la" /tmp/upstart.log 2&1 # LOGFILE=/var/log/logfile.`date +%Y-%m-%d`.log # exec su - $RUN_AS_USER -c "inosync -d -c /etc/inosync/inosync_rsyncuser.py" $LOGFILE 2&1 # exec su -c "ls -la" /tmp/upstart.log 2&1 # emit inosync_running end script

• How to list rpm packages/subpackages sorted by total size

  - by smci

  Looking for an easy way to postprocess rpm -q output so it reports the total size of all subpackages matching a regexp, e.g. see the aspell* example below. (Short of scripting it with Python/PERL/awk, which is the next step) (Motivation: I'm trying to remove a few Gb of unnecessary packages from a CentOS install, so I'm trying to track down things that are a) large b) unnecessary and c) not dependencies of anything useful like gnome. Ultimately I want to pipe the ouput through sort -n to what the space hogs are, before doing rpm -e) My reporting command looks like [1]: cat unwanted | xargs rpm -q --qf '%9.{size} %{name}\n' > unwanted.size and here's just one example where I'd like to see rpm's total for all aspell* subpackages: root# rpm -q --qf '%9.{size} %{name}\n' `rpm -qa | grep aspell` 1040974 aspell 16417158 aspell-es 4862676 aspell-sv 4334067 aspell-en 23329116 aspell-fr 13075210 aspell-de 39342410 aspell-it 8655094 aspell-ca 62267635 aspell-cs 16714477 aspell-da 17579484 aspell-el 10625591 aspell-no 60719347 aspell-pl 12907088 aspell-pt 8007946 aspell-nl 9425163 aspell-cy Three extra nice-to-have things: list the dependencies/depending packages of each group (so I can figure out the uninstall order) Also, if you could group them by package group, that would be totally neat. Human-readable size units like 'M'/'G' (like ls -h does). Can be done with regexp and rounding on the size field. Footnote: I'm surprised up2date and yum don't add this sort of intelligence. Ideally you would want to see a tree of group-package-subpackage, with rolled-up sizes. Footnote 2: I see yum erase aspell* does actually produce this summary - but not in a query command. [1] where unwanted.txt is a textfile of unnecessary packages obtained by diffing the output of: yum list installed | sed -e 's/\..*//g' > installed.txt diff --suppress-common-lines centos4_minimal.txt installed.txt | grep '>' and centos4_minimal.txt came from the Google doc given by that helpful blogger.

• Problem running mysql client, cannot connect to mysql server

  - by ehsanul

  Edit3: Thanks for the help everyone. Sorry for wasting anybody's time, but it seems like a simple reboot solved it. I should've known better, but I just had the assumption that the "restart" solution is mostly valid just for MS Windows (no offense). I'll keep this in mind before I ask a question here again. I installed the mysql-client-5.0 and mysql-server-5.0 packages on Ubuntu 8.04, using sudo apt-get install. When I try to run the "mysql" command, I get the following error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) To verify that mysql server is running, I tried this, and it does seem to be running, with the correct socket too: $ ps aux | grep mysql root 13388 0.0 0.0 1772 528 ? S 06:24 0:00 /bin/sh /usr/bin/mysqld_safe mysql 13553 0.0 1.4 127012 15332 ?

Note that I'm completely new to mysql. Edit: As requested in comments, the exact command that is returning the error is simply "sudo mysql". And when I check netstats for active networks services, I do see an entry for port 3306, with Protocol: tcp, IP Source: 127.0.0.1, State: LISTEN Edit2: It appears as if the /var/run/mysqld/mysqld.sock socket doesn't exist (if I'm interpreting the following output correctly): $ ls -al /var/run/mysqld/ total 0 drwxr-xr-x 2 mysql root 40 2009-08-06 06:36 . drwxr-xr-x 20 root root 860 2009-08-06 06:25 ..

• Nexus 1000v VEM fails on 2 out of 8 hosts.

  - by cougar694u

  I have 8 ESXi hosts. I do a fresh install from the installable CD directly to 4u1. We have another 2-node cluster with a working Nexus 1000v primary & secondary. Everything's up and running. I installed 6 hosts and everything worked great, migrated them to the Nexus DVS, and VUM installed the modules. I did the 7th host, and when I tried to migrate it to the DVS, it failed with the following error: Cannot complete a Distributed Virtual Switch operation for one or more host memebers. DVS Operation failed on host , error durring the configuration of the host: create dvswitch failed with the following error message: SysinfoException: Node (VSI_NODE_net_create) ; Status(bad0003)= Not found ; Message = Instance(0): Inpute(3) DvsPortset-0 256 cisco_nexus_1000v got (vim.fault.PlatformConfigFault) exception Then, I tried to do host 8, and got the exact same problem. It worked about 15 minutes prior when I did host 6, nothing changed, then went to host 7 and it failed. If I try to remediate either of these two hosts, either patches or extensions, it fails. Anyone else have these problems?

• Active Directory Domain Services - Network Name Cannot be Found

  - by Arief

  I have really weird problem that I could not explain. I am trying to redirect all users home folder to the new server. I have copied all the files including the permissions to the new server. All I need to do is to update the user profile for home folder by changing the server name. However, I got this message when I enter the new server name: My server that serving as AD can resolve the name by ping and nslookup of the server name. The only thing that I don't understand why the MMC cannot resolve the name. I did change with the IP Address and I still get the same error message. Thank you so much for your help. UPDATE: I know what seems to be a problem, but I don't know how to fix it. The new server that will serve all Home folder is actually sitting in the cloud with different IP Address as the Domain Controller. The Domain Controller is sitting locally in the office with 10.0.0.0/24 IP Addresses. The new server that is sitting in on Data Centre is on 172.10.10.10/24 IP Addresses. The static route has been set up on both end, and the DNS as well. I believe this is the issue. Does anyone how to overcome this situation? Thank you.

• VMware Workstation executes nonexisting and outdated File

  - by RED SOFT ADAIR-StefanWoe

  I execute a command line program from a VM (VMware 7.1.1) with Windows XP. The executable file is located on the host machine. If i start a command line in the VM, using a drive mounted as .host\SharedFolders i see the following: D:\projects\myProgram\WinRel>dir myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe D:\projects\myProgram\WinRel>myProgram.exe Processing BuildFeb 26 2009 This is wrong! The whole execution of the program behaves like the version that is outdated more than one year! I triple checked that there is no confusion or anything If i start the Program on the host or if i even start it from the VM using a UNC Path, it shows the last build date and executes as expected: C:\>dir \\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe C:\>\\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe Processing Build: Sep 2 2010 Can this behavior somehow be explained? There MUST be a cache for the host mounted drive. The program it executes does not exist anymore! If i remove it from the host, the VM can not execute it anymore. If i restore it, the behavior becomes the same again.

• If spaces in filenames are possible, why do some of us still avoid using them?

  - by Chris W. Rea

  Somebody I know expressed irritation today regarding those of us who tend not to use spaces in our filenames, e.g. NamingThingsLikeThis.txt -- despite most modern operating systems supporting spaces in filenames. Non-technical people must look at filenames created by geeks and wonder where we learned English. So, what are the reasons that spaces in filenames are avoided or discouraged? The most obvious reason I could think of, and why I typically avoid it, are the extra quotes required on the command line when dealing with such files. Are there any other significant reasons, other than the practice being a vestigial preference? UPDATE: Thanks for all your answers! I'm surprised how popular this was. So, here's a summary: Six Reasons Why Geeks Prefer Filenames Without Spaces In Them It's irritating to put quotes around them when referenced on the command line (or elsewhere.) Some older operating systems didn't used to support them and us old dogs are used to that. Some tools still don't support spaces in filenames at all or very well. (But they should.) It's irritating to escape spaces when used where spaces must be escaped, such as URLs. Certain unenlightened services (e.g. file hosting, webmail) remove or replace spaces anyway! Names without spaces can be shorter, which is sometimes desirable as paths are limited.

• How do I stop MSYS from transforming my compiler options?

  - by Carl Norum

  Is there a way to stop MSYS/MinGW from transforming what it thinks are paths on my command lines? I have a project that's using nmake & Microsoft Visual Studio 2003 (yeecccch). I have the build system all ported and ready to go for GNU make (and tested with Cygwin). Something weird is happening to my compiler flags when I try to compile in an MSYS environment, though. Here's a simplified example: $ cl /nologo Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.6030 for 80x86 Copyright (C) Microsoft Corporation. All rights reserved. /out:nologo.exe C:/msys/1.0/nologo LINK : fatal error LNK1181: cannot open input file 'C:/msys/1.0/nologo.obj' As you can see, MSYS is transforming the /nologo compiler switch into a windows path, and then sending that to the compiler. I really don't want this to happen - in fact I'd be happy if MSYS never transformed any paths - my build system had to take care of all that when I first ported to Cygwin. Is there a way to make that happen? It does work to change the command to $ cl -nologo Which produces the expected results, but this build system is very large and very painful to update. I really don't want to have to go in and change every use of a / for a flag to a -. In particular, there may be tools that don't support the use of the - at all, and then I'll really be stuck. Thanks for any suggestions!

• How often is CRL refreshed, and how to force it to be?

  - by lockstock

  I have a web service running under IIS 7 that requires an X509 client certificate. I know that the server that it rus on needs access to DigiCert.com in order to be able to get the CRL (Certificate Revocation List). There is a need to change our proxy so I am attempting to investigate the impact of doing so. I have removed the global proxy settings using the command netsh winhttp proxy refesh, and also deleted the CRL cache using the command certutil -URLcache CRL delete. However, after doing this, all calls to the web service still succeed. This suggests to me that I am missing something here. So; If the CRL cache is cleared and the server has no way of refreshing the CRL, why do web service requets not return http 403?. I have been unable to find adequate information from googling nor from my colleagues. The reason I want it to fail is that I will not be confident that the new proxy settings work until I can see it broken first, if that makes sense. I would also like to be able to force the CRL to be refeshed in order to ensure that the new proxy settings work

• Configuring vsftpd with nginx on Ubuntu 12.04 LTS

  - by arby

  I've attempted to configure a nginx / vsftpd server on Ubuntu 12.04 LTS (via amazon ec2) a couple times now, but I seem to keep making a mistake along the way. Currently, when I try to connect to my ftp server it takes a minute or so before it connects. Then when I issue a command, they all timeout with an operation failed error. Aside from these issues, I'm not completely confident with the file ownership & permissions or the configuration / settings. So, I think it's best if I just re-install and re-configure correctly. I believe the nginx installation comes with a default user of www-data:www-data and web root directory ownership by root:root. Vsftpd, however, needs to have a user created with the same group as the nginx user (www-data), and the same home directory as the nginx server (/usr/share/nginx/www), with g+w chmod permissions granted on that directory. The vsftpd.conf file should disable anonymous logins and enable local logins, file writing, and chroot local users. In my previous config, I had /bin/false set for the ftp user's shell and pam_shells.so disabled. I also had local_umask set to 0027. So, starting with a fresh ec2 instance, I've got: sudo apt-get install vsftpd sudo apt-get install nginx For the firewall I issued the command (not sure if necessary): sudo ufw allow ftp Which commands / config is recommended from here? I only need 1 ftp user that I can use to login with my ftp client to modify the single nginx web domain, which will need php & sql for WordPress.

• SSH dynamic port forwarding, "Connection refused"

  - by crodjer

  I am trying to do dynamic portforwarding using openssh through a remote computer following this command: ssh -D 6789 rohan@<remote_ip> -p <remote_port> This should set up a socks server on my comp as I assume. I am able to use this for normal browsing but can't connect to IRC or remote ssh (through proxychains). I get this error: channel 3: open failed: connect failed: Connection refused A high verbosity level output of the error: $ debug1: Connection to port 6789 forwarding to socks port 0 requested. debug2: fd 9 setting TCP_NODELAY debug2: fd 9 setting O_NONBLOCK debug3: fd 9 is O_NONBLOCK debug1: channel 3: new [dynamic-tcpip] debug2: channel 3: pre_dynamic: have 0 debug2: channel 3: pre_dynamic: have 4 debug2: channel 3: decode socks5 debug2: channel 3: socks5 auth done debug2: channel 3: pre_dynamic: need more debug2: channel 3: pre_dynamic: have 0 debug2: channel 3: pre_dynamic: have 10 debug2: channel 3: decode socks5 debug2: channel 3: socks5 post auth debug2: channel 3: dynamic request: socks5 host 4.2.2.2 port 53 command 1 debug3: Wrote 96 bytes for a total of 3335 channel 3: open failed: connect failed: Connection refused debug2: channel 3: zombie debug2: channel 3: garbage collecting debug1: channel 3: free: direct-tcpip: listening port 6789 for 4.2.2.2 port 53, connect from 127.0.0.1 port 33694, nchannels 4 debug3: channel 3: status: The following connections are open: #2 client-session (t4 r0 i0/0 o0/0 fd 6/7 cfd -1) debug3: channel 3: close_fds r 9 w 9 e -1 c -1 I googled for this too, but couldn't find any solutions.

• VMware virtual machine network devices malfunctioning

  - by sheepz

  I'm running Ubuntu 10.04 LTS and VMvware workstation 7.0.1 build-227600. The virtual machine i'm running in VMware is a custom distribution built on Debian Linux version 3.1. I'm still pretty much a beginner with UNIX administration. After having messed around with the vmware (changed only the name of the folder, the vmx and and other .v* files accordingly in which the .vmx was situated, and the configuration in the vmx file accordingly), the network devices on the virtual machine do not work anymore. The virtual machine is used for securely sending messages. The virtual machine: As far as I know, this perl file called proxy-gen-ifalias eth0 is responsible for properly setting up the two virtual network devices eth0 and eth1. The Virtual machine comes with a GUI interface in which I have set up two ethernet network devices, one internal, the other external. Now, after having messed around with this, the UI gives me this error message: perl proxy-gen-ifalias eth0 /etc/modprobe.d/alias-eth0 /sbin/update-modules perl proxy-gen-ifalias eth1 /etc/modprobe.d/alias-eth1 /sbin/update-modules ifdown eth0 ifdown: interface eth0 not configured ifdown eth1 ifdown: interface eth1 not configured perl proxy-gen-netcfg /etc/network/interfaces ifup eth0 SICCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0. ifconfig eth0 eth0: error fetching interface information: Device not found make: *** [/etc/network/interfaces] Error 1 ~ Here are the contents of the two perl files referred to in the message: paste.pocoo.org/show/2AMzAYhoCRZqlGY7wUFk/ proxy-gen-netcfg

• org-sort multi: date/time (?d ?t) | priority (?p) | title (?a)

  - by lawlist

  Is anyone aware of an org-sort function / modification that can refile / organize a group of TODO so that it sorts them by three (3) criteria: first sort by due date, second sort by priority, and third sort by by title of the task? EDIT: I believe that org-sort by deadline (?d) has a bug that cannot properly handle undated tasks. I am working on a workaround (i.e., moving the undated todo to a different heading before the deadline (?d) sort occurs), but perhaps the best thing to do would be to try and fix the original sorting function. Development of the workaround can be found in this thread (i.e., moving the undated tasks to a different heading in one fell swoop): How to automate org-refile for multiple todo EDIT: Apparently, the following code (ancient history) that I found on the internet was eventually modified and included as a part of org-sort-entries. Unfortunately, undated todo are not properly sorted when sorting by deadline -- i.e., they are mixed in with the dated todo. ;; multiple sort (defun org-sort-multi (&rest sort-types) "Multiple sorts on a certain level of an outline tree, or plain list items. SORT-TYPES is a list where each entry is either a character or a cons pair (BOOL . CHAR), where BOOL is whether or not to sort case-sensitively, and CHAR is one of the characters defined in `org-sort-entries-or-items'. Entries are applied in back to front order. Example: To sort first by TODO status, then by priority, then by date, then alphabetically (case-sensitive) use the following call: (org-sort-multi '(?d ?p ?t (t . ?a)))" (interactive) (dolist (x (nreverse sort-types)) (when (char-valid-p x) (setq x (cons nil x))) (condition-case nil (org-sort-entries (car x) (cdr x)) (error nil)))) ;; sort current level (defun lawlist-sort (&rest sort-types) "Sort the current org level.

• Troubleshooting certificate issues

  - by Weezy

  I'm trying to access my (European Parliament) Webmail from a Linux/Firefox machine at the following address and I get security warning messages explaining that the identity of the site cannot be verified (the error message is in french). But this only happens with Linux/Firefox from one machine. Here's the address: https://webmail.europarl.europa.eu/ (and I'm trying to access it from my home, not from the EP). And here's the detailed error message: webmail.europarl.europa.eu utilise un certificat de sécurité invalide. Le certificat n'est pas sûr car l'autorité délivrant le certificat est inconnue. (Code d'erreur : sec_error_unknown_issuer) So basically, if I translate, it is telling that the webmail.europarl.europa.eu certificate is invalid because the authority that delivered the certificate is unknown. I do only get this invalid certificate thing on Linux/Firefox. From a MacBookPro running Safari, I go to what looks like the correct webmail login page. From the same Linux machine, but using another user account and Chrome instead of Firefox, I go to what looks like the correct webmail login page. So there are several possibilities, here are a few ones: Firefox is right and my Linux box has been hacked Firefox is right and detecting something that neither Chrome nor Safari is detecting (like, say, my router that may be hacked) Safari on the MacBook Pro and Chrome on Linux are both correct and it is just Firefox on Linux that is wrongly stressing me when everything is normal. How do I know which one of these possibilities (or any other) is correct? How can I troubleshoot what is going on with either Linux/Firefox or with the parliament's webmail?

• Recommended programming language for linux server management and web ui integration

  - by Brendan Martens

  I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects that already integrate management of many systems into a single cohesive web ui, except Landscape (not free,) Ebox (ebox control center not free) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo. Also, only manages one system.) Thanks for any ideas! Update: I am not looking to reinvent the wheel of systems management, I just want to "glue" many preexisting and excellent tools together where possible and appropriate; this is why I wonder about what languages can interact well with pre-existing command line tools, while making them manageable with a web ui.

• Time not propagating to machines on Windows domain

  - by rbeier

  We have a two-domain Active Directory forest: ourcompany.com at the root, and prod.ourcompany.com for production servers. Time is propagating properly through the root domain, but servers in the child domain are unable to sync via NTP. So the time on these servers is starting to drift, since they're relying only on the hardware clock. WHen I type "net time" on one of the production servers, I get the following error: Could not locate a time-server. More help is available by typing NET HELPMSG 3912. When I type "w32tm /resync", i get the following: Sending resync command to local computer The computer did not resync because no time data was available. "w32tm /query /source" shows the following: Free-running System Clock We have three domain controllers in the prod.ourcompany.com subdomain (overkill, but the result of a migration - we haven't gotten rid of one of the old ones yet.) To complicate matters, the domain controllers are all virtualized, running on two different physical hosts. But the time on the domain controllers themselves is accurate - the servers that aren't DCs are the ones having problems. Two of the DCs are running Server 2003, including the PDC emulator. The third DC is running Server 2008. (I could move the PDC emulator role to the 2008 machine if that would help.) The non-DC servers are all running Server 2008. All other Active Directory functionality works fine in the production domain - we're only seeing problems with NTP. I can manually sync each machine to the time source (the PDC emulator) by doing the following: net time \\dc1.prod.ourcompany.com /set /y But this is just a one-off, and it doesn't cause automated time syncing to start working. I guess I could create a scheduled task which runs the above command periodically, but I'm hoping there's a better way. Does anyone have any ideas as to why this isn't working, and what we can do to fix it? Thanks for your help, Richard
