  • Problem opening XWindows programs with xming and SSH Secure Shell

    - by Brian
    I've installed SSH Secure Shell and xming on my laptop running Windows 7 (64-bit). I'm having trouble starting X Windows applications from the SSH console. I've been able to do it in the past. I've pretty much determined that it's not a server issue because I've tried it on two different servers (both servers are running RHEL 5). Running "echo $DISPLAY" on either server gave me "localhost:10.0". My XLaunch configuration settings are: Multiple Windows, 10 (display number), and Start no client. Once xming has launched, I'll try to execute something like "firefox" and I get this back: The application 'firefox' lost its connection to the display localhost:10.0; most likely the X server was shut down or you killed/destroyed the application. I've already checked to make sure that the X server is running and it is: root 12579 2689 0 Feb14 tty7 00:04:23 /usr/bin/Xorg :0 -br -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7 Additionally, X11 Tunneling has been enabled in SSH as well as SSH 2 connections.

  • Connecting both WAN and LAN ports to the same hub

    - by C. Lee
    For some reason I wish to connect the WAN port and the LAN port on a router to the same hub and make the hub is connected to both networks, the Internet and a private network. Below is a diagram of the network configuration I'd like to build. I tried this and it didn't work as expected. PC 1 has no problem, but PC 2 cannot connect to the Internet. When I ping 192.168.0.1 from PC 2, all packets are lost. It works well when PC 2 is connected directly to the router. What's the problem with the network configuration above?

I think is an error with my ProxyPass but I don´t know what is.

  • Can't connect using Jail SFTP account

    - by Fazal
    I've been following this tutorial "Limiting Access with SFTP Jails on Debian and Ubuntu" and whilst I've had no errors setting it up, I've had issues on Ubuntu 10.04LTS logging in as a user on a virtualhost. I've changed my SSH port to 22022, and enter all the credentials when attempting to login. I ran these commands to add a user to the virtualhost: # useradd -d /srv/www/[domain] [username] # passwd [username] # usermod -G filetransfer [username] # chown [username]:[username] /srv/www/[domain]/public_html I should add that this is the only time I've setup the user they have no other /home directories or such. The directory that does exist is at /srv/www/example.com/public_html When I try using a desktop package such as cyberduck to login to the site, I keep getting a "Login failed with this username or password". I am completely lost as what to do next... The reason why I'm trying this method is because I want my clients to use SFTP and not FTP to upload files to their websites. Any help or direction is appreciated.

  • Convert svn repository to hg - authentication fails

    - by Kim L
    I'm trying to convert an existing svn repository to a mercurial repo with the following command hg convert <repository> <folder> My problem is that the svn repository's authentication is done with p12 certificates. I'm a bit lost on how to configure the certificate for the hg client so that I can pull the svn repo and convert it. Currently, if I try to run the above command, I get initializing destination hg-client repository abort: error: _ssl.c:480: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure In other words, it cannot find the required certificate. The question is, how do I configure my hg client so that it can use my certificate? I'm using the command line hg client on linux.

  • Only allow certain processes to connect to MS SQL

    - by Fred
    I've lost the source code for a very old application that connects to a MS SQL-server for some SQL queries. Since the login is hard-coded in the application I can't change the username/password on the server. One day the password will probably be known to the users and we surely need to change it. But how? One idea is to only allow the old application to do the queries on the SQL server and block out any other application like the query analyzer etc. Can I set process permission somehow? The SQL server (MS SQL 2005) and application (C++) are on the same machine It's too costly to rewrite the old program Thanks for help!

  • Weird unexpected image compression on a web server running Apache on Ubuntu?

    - by Billy Bob Thornton
    I have a weird problem on my production web server running Apache on Ubuntu: it compresses my images thereby dramatically lowering their quality! Actually I have two virtual hosts running, each located in a different folder. Wether I display .gif images by navigating on the two sites, or acceding them directly by their url, their size and quality are invariably degraded. I tried with three different browsers: same problem. Using them on other sites on the Web: no problem. Of course I disabled mod_deflate on the server (which should not compress images anyway), but the phenomenon remains. On my local développement server, running the same configuration, everything is Ok. Now I'm completely lost! For the record, my configuration: Ubuntu 10.04, Apache 2, Php 5.

  • Can't add printer on Windows XP

    - by SuperFurryToad
    I've added a HP 4250 printer to about half a dozen Windows XP PCs in our office without any problems whatsoever, but for some reason I haven't been able to add it to one particular PC today. I go through the Add Printer wizard to add a local printer attached to the PC, enter the new port number as a Standard TCP/IP Port, install the driver. At the end of the wizard I get the following error message: Full error message: "windows cannot connect to the printer. either the printer name was typed incorrectly, or the specified printer has lost its connection to the server." This doesn't make any sense as I am able to ping the printer from the PC. The print spooler is running, and any firewall software on the local PC is switched off.

  • Customize autoindent settings in VIMRC file

    - by Shane Reustle
    I have autoindent enabled in my .vimrc file but have run into an annoying bug/feature. For example, when I'm tabbed in 3 times, and I hit return, the new line is also tabbed in 3 times. Then when I hit enter again, that new line is also indented 3 times, as it should. The problem occurs when I go back up to the previous line (the first of the 2 new lines). VIM automatically removes the whitespace because it saw it as an empty line. Is there a way to disable this from happening? I'd like to be able to back to coding like this: function test(){ <return> <return> } <up> <right> Thanks!

  • Can I rebuild degraded RAID1 on a SAS 5 i controller with a larger mirror drive size?

    - by Kenny
    Hi, A drive failed on a Dell SAS 5i controller - see controller bios screengrab: http://imagebin.ca/view/SkZbszA.html The primary is a 160GB 10k sata drive. I added a 250GB 7k rpm drive in the hope that the array would rebuild onto this drive. This did not happen. (assuming that the controller would just operate at the speed of the slowest drive) The controller could see the new drive, but it didn't automatically rebuild the raid1 onto this drive. (my assumption is that it did not do this rebuild as the drive sizes are different). There was an option to add the new drive to the existing raid1 array - but when I tried this a message appeared stating that all data on the array would be lost. (I didn't get a screenshot of this message, I will later) Should the SAS 5i allow me to rebuild the array onto a larger drive? Is the option to add the drive to the array the right way to go? Many thanks!

Lets assume, notebooks have private IP 192.168.1.2 and 192.168.1.3 I am kind of lost here, would appreciate some help (I need to be able remote desktop to both notebooks)

  • Stop a particular key getting captured by rdesktop

    - by user18151
    Hello, I want F12 to be not capture by my rdesktop while in fullscreen, so that I can do whatever stuff I'm doing on my remote Windows computer, but pressing F12 would bring down yakuake, and I can type down my commands, or use vim etc for whatever I'm doing. Is there any possible way to do this? I tried playing with keymaps, but that didn't help. I set F12 to inhibit, but that seems to have stopped sending F12 altogether, rather than let gnome catch it and let yakuake pop up. Would be really grateful for answers. I am ready to do my homework, if someone could please just give me pointers etc. Thanks :). Sidenote: My current arranement stems from my large monitor in lab, and small personal laptop monitor, and the laptop has Windows 7. My lab computer has Linux, on which I do my coding work.

  • Why are my files in /var/lock and where did they just go?!

    - by Nicky Hajal
    I am hosting a website on Debian 5.0 & Apache2. Today one of my websites was down, Apache said it couldn't find the directory. I located the files and the whole site once in /var/www/site was now /var/lock/site. All the files were present. I was confused, but figured I'd just move it back. mv /var/lock/site /var/www All looked fine... Except that only the directories moved and the files appear to be lost! I am working on restoring from backups but I would really love to know what happened and where my files went (the backups are a few days old). Thanks for your help!

  • DFS-R (2008 and R2) 2 node server cluster, all file writes end in conflictAndDeleted

    - by Andrew Gauger
    Both servers in a 2 server cluster are reporting event 4412 20,000 times per day. If I sit in the conflictAndDetected folder I can observe files appearing and disappearing. Users report that their files saved by peers at the same location are overriding each other. The configuration began with a single server, then DFS-R was set up using the 2008 R2 wizard that set up the share on the second server. DFSN was set up independently. Windows users have drives mapped using domain based namespace (\domain.com\share). Mac users are pointed directly to the new server share created by DFS-R. It is PC users indicating most of the lost files, but there has been 2 reports by Mac users about files reverting.

  • What email providers have extremely high reliability and robust SLAs?

    - by Benjamin Manns
    My dad is a professor who does part-time law practice. He had been using his university email address for professional correspondence, when he found out that the university had permanently lost 16 business-related emails in their spam filter (with no apology, notification, or compensation). What I am looking for now is an email provider (preferably with Exchange, but not required) with very high reliability and a SLA that is basically an insurance policy. I have looked at Google Apps's SLA, but this will not suit. I am looking for a provider who will take $X per month in registration fees, and will: Alert me when there is any downtime. Promptly fix the issue Pay me a fee ($Y) whenever there is downtime. I want a significant, contractual reason for them to be diligent in their service. Free service for me is not enough.

  • Visio Losing My Diagrams!

    - by bobber205
    I've created under "Static Model-Top Package" 4 different sequence diagrams. Once I tried creating the fifth it won't keep it. I try to double click and open it and it opens the 4th one. I can delete the 5th one and create a new one. I can edit this but as soon as I go to another diagram, I've lost it and can only go back to the 4th one and edit that even though I right clicked the 5th one and selected "Open Sequence". What is going on? Has anyone else seen this Visio issue?

  • How can I use structured references to a column in an Excel macro?

    - by Eshwar
    Here's an example that will explain things: Sheets("Plot Data July").Select ActiveSheet.ListObjects("tPDJuly").Range.AutoFilter Field:=2 ActiveSheet.ListObjects("tPDJuly").Range.AutoFilter Field:=4 So as you can see above, Field:=2 is a relative reference to the second field in the table called "tPDJuly". So now if I add more columns, this number does not get updated. The field is actually called "Grade" in the table. So is there a way of coding this so that no matter which column it is in, "Grade" is always updated? I suppose one solution is that we add a line that find what is the column number for "Grade"?

  • Remote desktop connection issues in windows server 2003

    - by rboorgapally
    Hi all, We are running windows server 2003 at our work place. I have enabled the remote desktop connections. I have also added all the users who connect to the server(three to four people) to the RDC group of users. Many of these users are also having Administrator access. The problem we are facing is that the connection is suddenly lost when we are working on something. Also, at times the system restarts by itself. Is this issue related to the limit on the number of users able to connect to the system? If so, why does the system accept new connections and/or terminate the existing connections? Has this anything to do with the users having administrator access so that all have equal prority and that is why existing connections are stalled? Also, please differentiate between console remote desktop and non console remote desktop.

  • Can't connect to domain computers until reboot

    - by thealliedhacker
    I have a domain with about 300 Windows 7 and XP machines, with the domain controllers running Server 2003. Sometimes, I lose the ability to communicate/authenticate with some of the machines until I reboot my computer. This also happens from other computers and regardless of user account and operating system. In other words, say I'm on ComputerA, and I can't connect to ComputerX. I can go to ComputerB and connect to ComputerX, but ComputerB may not be able to connect to ComputerY. If you reboot ComputerA, then it will be able to connect to ComputerX again. Here are some messages from various utilities: sc: [SC] OpenSCManager FAILED 1722: The RPC server is unavailable. mmc (compmgmt.msc): Computer (computer name) cannot be managed. The network path was not found. explorer (\\computer): Windows cannot access \\(computer name). ping: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss) / Average = 1ms

  • 802.11 Capture Frame

    - by ALi
    I am using wireshark in monitor mode to capture all the frame. I buffered all the QosData in order to calculate the biterate of each station on the network. I calculate the biterate but it is not an accurate value. what i need to know is when the station use the network alone and when it uses it with another station? i know if two station with different wifi card for exemple ( st1 802.11g 54 Mb/s, st2 802.11n 300 Mb/s) if st1 uses alone the line the biterate used is 28 MB/s and if st2 uses alone the network the bit rate increase to approximately 150Mb/s but if the two station use the network at the same time the st1 lost about 80% of its bit rate because of the st1 wifi card thx in advance

  • CentOS: update a package from a repository safely on a production server

    - by dan
    Hello everybody. I have a CentOS server on a production environment. I need to update the PHP package that I installed using the REMI repository. Quite easy: yum update php But what is it going to happen if something goes wrong during the update? How can I rollback? What's the best technique to make sure not to compromise a production server due to an update? Is it maybe better to compile PHP from the source, rather than using a binary package? EDIT: I am not afraid of incompatibility between my code and the new PHP version (I have well tested that on development). I am more afraid of something going wrong while CentOS updated the binary (power cut, lost connection, unexpected conflit) Thanks, Dan

  • Free Google Docs alternative compatible with Opera

    - by f4k3
    Well gDocs isn't working ok, too many bugs and it's pretty slow (especially when saving documents). I have tried several alternatives: - Zoho - they say it's not compatible with Opera and it;s true - you even can't CTRL+V text - Buzzword - it's really slow, and some functions don't work properly (on all browsers) for example "increase indent" increases a random text indent - Etherpad - was taken over by google and is shut down - Peepel - it's a cool thing, almost a free virtual desktop in a browser but it's buggy - a saved a document, tried to open it end an error occured. the document was lost - OpenGoo - went commercial At the moment I'm testing ThinkFree Online - it'a a bit slow (Java :P) and some minor things don't work (like drag a toolbar) but it has cool functionalities (almost like OpenOffice! which I use at home), it actually works with opera (create, save, edit document). Maybe I'll try Scribd but is it a office/share platform? any other worth trying??
