  • git networking for small team

    - by takeshin
    I'm trying to set up git for my programming team. My setup is: 1. example.com (Ubuntu server) IP: 192.168.1.2 (public: xxx.yyy.yyy.zzz) main git repository in /var/www/testgit user: mot (root) 2. host2, Ubuntu IP: 192.168.1.101 git clone of main repo in ~/public_html/testgit1 user: nairda 3. host3, Ubuntu IP: 192.168.1.102 git clone of main repo in ~/www/testgit2 user: mot 4. host4, Windows Vista, Samba, msysgit IP: 192.168.1.103 git clone of main repo in c:\shared\testgit3 user: ataga I start a new main repo: cd /var/www/testgit1 git init Now, a lot of questions: Which groups and users do I have to create? How to set up required ssh keys? (I'm playing with gitosis, but with no success by now.) How to make the main repo visible to other hosts? How to clone this repo on the hosts? How to pull changes from others to main repo?

  • tptp/profiling of web-application within eclipse - no data collectors available

    - by AJ
    Hi, I have a problem with tptp/profiling within eclipse. Because at first I had some very strange problems, I downloaded the “TPTP all-in-one package” (tptp.runtime.allInOne.win32.win32.x86-TPTP-4.6.2.zip) and added the stuff I need (Jboss-Tools, etc.) I am using Windows XP SP3, Java 6u20, Eclipse 3.5.2.(, jboss-4.2.3.GA-jdk6) In "Profile Configurations"/Tab "Monitor" I got “IWAT0435E An error occurred when connecting to the host” and in the “Profile on Server” Window in the tab Monitor I got only “pre-JRE 1.5“ as choice. After disabling an enabling the IAC in “Preferences”/”Agent Controller” that IWAT...-problem was gone but now I don't get anything in the “Profile on Server”/”Monitor” tab, but it says “[Monitor] The launch requires at least one data collector to be selected.” any ideas?

  • Sun Grid Engine: Automatically Terminating Idle Interactive Jobs

    - by dmcer
    We're considering using Sun Grid Engine on a small compute cluster. Right now, the current set up is pretty crude and just involves having people ssh to an open machine to run their jobs. We'd like to allow interactive jobs, since that should ease the transition from manually starting jobs to starting them using qsub. But, there is some concern that, if we do, people might accidentally leave their interactive sessions idle and block other jobs from being run on the machines. The issue isn't just theoretical, since we previously tried using OpenPBS and there was a problem with people opening up an interactive job in a screen session and essentially camping on a machine. Is there anyway to configure SGE to automatically kill idle interactive jobs? It looks like this was requested as an enhancement (Issue #:2447) way back in 2007. But, it doesn't seem like the request ever got implemented.

  • How can I use scp without providing a password

    - by Tim
    I have asked a question before in here. My question was that I tried to give my password to scp via piping echo mypassword | scp [email protected]:project/* ~/project/ However it still asks me to manually input the password. How should I specify mypassword to scp in commands? I still don't understand one of the replies. what is a input stream by TTY, for example? What are the common ways for a input stream? How to know what type of input stream a stdin input to a command is? For example that of ssh/scp.

  • PPTP network for server backend LAN?

    - by Sebastian Hoitz
    Here is our problem: We have several webservers, which should be reached from public. The database servers that store the data for the web apps on those webservers though shall not have a public IP. So, since I want to be able to connect to the SQL servers using ssh for example, and those servers need to talk with each other, I had this idea: Internet | ------------------ | | Webserver 1 Webserver 2 Database Server | | | -------------- vLAN -------------- | PPTP | Workstation (my PC) My idea was that I can connect to the vLAN using PPTP so that I have access to all servers in that LAN, but the database server remains unvisible to the public. Is this infrastructure a good idea?

  • How to setup separate MySQL and PHP VPS servers

    - by Fazal
    Someone recommended I should have my MySQL server separate from my Apache/PHP server in case of hacking and such. By visiting linode, slicehost and various articles here on serverfault I've managed to cobble together a decent set of instructions on how to do the Apache/PHP bit. I'm using Rackspace VPS and they provide an internal IP for each server. If I setup a MySQL VPS, should I assume that I would just add the internal IP for the database host? And I guess that I would only need to open up my default ssh port and mysql ports and install phpmyadmin on there? Ideally I would have webserver.mydomain.com and dbserver.mydomain.com (two 256mb VPS's) with servermin on webserver.mydomain.com and phpmyadmin on dbserver.mydomain.com. If anyone has any guides or advice on how to setup this type of solution I'd be more then grateful!

  • Linux halts every few seconds

    - by Zeppomedio
    We're having an issue where one our Linux boxes (Ubuntu 10.04 LTS, running on EC2 with a quadruple-large size, 68GB of RAM and 8 virtual cores with 3.25GHz each) freezes up every few seconds. Typing in an ssh session will freeze, and running strace on one of the Postgresql processes that's running usually shows: 02:37:41.567990 semop(7831581, {{3, -1, 0}}, 1 for a few seconds before it proceeds (it always gets stuck at that semop). OProfile shows that most of the time is spent in the kernel (60%) versus 37% in Postgresql. The result of these halts (which began suddenly a day ago) is that load on the box has gone from 0.7 to 10+, and causes our entire stack to slow done. Any ideas on how to track down what's going on? iostat doesn't show the disks being particularly slow or overloaded, and top shows user cpu % spike from 8% to about 40% whenever these back-ups happen.

  • Fastest light-weight image viewer over forwarded x11 session (linux)

    - by Matthew
    I have a slow network connection over which I'm forwarding x11 over ssh. I want to view images on the remote host (Ubuntu) quickly and efficiently. I'm looking for an image viewer that will take into account the image viewer window's resolution and downsize the image before sending it over the network, instead of sending the full size image. The images I want to view will be around 5MB and I only need to be able to browse through tiny thumbnails of the images to identify the image I'm looking for. It is not necessary to be able to see more than one image at a time. Highest speed over slow network connection is the priority. Thanks! Matthew EDIT: It's possible that the way x11 forwarding works, only the image at the display resolution will be transferred anyway. If that's true, please confirm and the question still stands for which image viewer will be the fastest over a slow connection

  • Suggest methods for testing changes to "pam.d/common-*" files

    - by Jamie
    How do I test the changes to the pam.d configuration files: Do I need to restart the PAM service to test the changes? Should I go through every service listed in the /etc/pam.d/ directory? I'm about to make changes to the pam.d/common-* files in an effort to put an Ubuntu box into an active directory controlled network. I'm just learning what to do, so I'm preparing the configuration in a VM, which I plan to deploy in metal in the coming week. It is a clean install of Ubuntu 10.04 Beta 2 server, so other than SSH daemon, all other services are stock.

  • SmartSVN - Unable to create new repository profile

    - by Sandeepan Nath
    I have just installed SmartSVN on this fedora system. The application starts (on running ./smartsvn.sh) with its usual UI but many things are not working. Creating New repository profile Trying to create a new repository profile (Repositories- Repository Profiles- Add) An Error occurred while processing an SVN command - Cannot connect to 'svn+ssh://192.168.0.103': There was a problem while connecting to 192.168.0.103:22 Quick Checkout Trying to do Quick Checkout (less configuration) An Error occurred while processing an SVN command - Malformed XML. Some Observations When I run the smartsvn.sh file like this:- ./smartsvn.sh It shows this in the console - Warning: /bin/java does not exist Could not lock /root/.smartsvn/_lock_ Switched to running instance I was using SmartSVN in another system before this where it was working. There too, it was showing the warning like Warning: /bin/java does not exist but this part was not showing:- Could not lock /root/.smartsvn/_lock_ Switched to running instance I have only JRE installed in both the systems and not JDK.

  • Clone remote CentOS server to local test server?

    - by dannymcc
    We have a dedicated server running ContOS 5.5. The server runs our Magento store and a basic php website with mysql. I have a spare rack server in my office (HP ProLiant DL360 G4) that has more than enough storage space to store a duplicate of our dedicated server. I would like to clone the dedicated server entirely and have a local duplicate. It wouldn't need to be kept in sync because I can do that with GIT. The reason I want to do this is simple; learn more about the dedicated server and CentOS. Is this possible? I have SSH access to the dedicated server and obviously complete access to the local server.

  • What are the common Control combinations in a terminal setting

    - by Hamish Downer
    I would like to have a good guide to the common Control key combinations in use in bash (and similar) shells and the combinations used by common programs in use in those shells. My particular motivation is to be able to run GNU screen on one computer, ssh to a second computer and use screen and irssi on that computer. So I need to use something other than Ctrl-A to control one of the screen sessions. So I need to know what are Control key combinations are safe to use. But I imagine this list would be useful for others who want to bind custom actions to Control key combinations. I reckon we'd be best to group the Control key combinations by application (eg. bash itself, screen, vim, emacs), to make it easy to spot the applications you use or can ignore. So please one application per answer - hope that works.

  • os x 10.4 server enable mail for account via terminal

    - by Chris
    Hello- I have an account on an OS X 10.4 server that I don't have physical access to (must use SSH). For arguments sake, let's call the account 'Bob'. Bob's account exists and appears to be fully functional, however he does not have email. How do I enable, via terminal, email for Bob's account, such that he can receive email at [email protected]? I already have the mail server all set up with several working accounts in it, I just need to add Bob. I have searched all over Google for over six hours now, but can't seem to find an answer that fits my situation. Any help is appreciated. P.S. - I am not adverse to just deleting the account and starting over, if that would make things easier...

  • how to enable remote access to a MySQL server on an AZURE virtual machine

    - by Rees
    I have an AZURE virtual machine with a MySQL server installed on it running ubuntu 13.04. I am trying to remote connect to the MySQL server however get the simple error "Can't connect to MySQL server on {IP}" I have already done the follow: * commented out the bind-address within the /etc/mysql/my.cnf * commented out skip-external-locking within the same my.cnf * "ufw allow mysql" * "iptables -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT" * setup an AZURE endpoint for mysql * "sudo netstat -lpn | grep 3306" does indeed show mysql LISTENING * "GRANT ALL ON *.* TO remote@'%' IDENTIFIED BY 'password'; * "GRANT ALL ON *.* TO remote@'localhost' IDENTIFIED BY 'password'; * "/etc/init.d/mysql restart" * I can connect via SSH tunneling, but not without it * I have spun up an identical ubuntu 13.04 server on rackspace and SUCCESSFULLY connected using the same procedures outlined here. NONE of the above works on my azure server however. I thought the creation of an endpoint would work, but no luck. Any help please? Is there something I'm missing entirely?

  • MySQL blocking new connections, and mysqladmin flush-hosts

    - by aidan
    I'm running MySQL on a remote server, and it suddenly started rejecting all connections: $ mysql -h 192.168.1.10 -u root -p ERROR 1129 (00000): Host 'web' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' So, I try this flush-hosts command... $ mysqladmin flush-hosts -h 192.168.1.10 -u root -p mysqladmin: connect to server at '192.168.1.10' failed error: 'Host 'web' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'' I.e. it's blocking the very un-blocking tool it recommends. Am I doing it wrong, or will I have to resort to ssh/cpanel/physical access?

  • Setting up Samba shares on a Linux VPS

    - by 101265052760541259879
    Hi, I'm trying to set up a folder that can be accessed via Windows clients over the net on my Linux VPS on which our companies website resides. I know a little bit about Linux, and have used Samba before to browse Windows shares from a Linux laptop. I'm guessing it's possible to do the reverse - to share a folder from Linux TO a Windows client. I have root SSH access to the VPS, would anyknow know what steps I need to take to set up the share, and how I can secure it, ideally with a simple username/password so the Windows clients can connect easily? Many thanks, Jack

  • Automated builds of BizTalk 2009 projects using Team System 2008 Build

    - by Doug
    I'm trying to configure automated build of BizTalk 2009 projects using Team Foundation Server 2008. We have a staging server which has BizTalk 2009 installed. I ran the Team Foundation Server Build Setup on this server, and it can build non-BizTalk projects OK. However, BizTalk projects fail to build. I suspected something was amiss when "Deployment" was not a valid build type! I tried copying various things over from a developer PC which has BizTalk and Visual Studio 2008 installed, but still couldn't get it to work. I don't really want to install Visual Studio on the staging server, but without it the "Developer Tools and SDK" option in the BizTalk install is greyed out. I guess I need this in order for BizTalk projects to compile. So, my question is can a BizTalk 2009 server be used as a TFS build agent to build BizTalk projects without having Visual Studio installed. If the answer is no, what's the smallest part of VS that can be installed to get this to work? Thanks in advance.

  • How to create an alias for linux server name?

    - by Radek
    The openSUSE server name is 'darkhelmet'. I want to create an alias 'dh' for it. So I can also type 'ssh dh' and 'http://dh' would work too. What file/files and where do I have to edit to make this happen? Extract from /etc/hosts from darkhelmet 127.0.0.1 localhost # special IPv6 addresses ::1 localhost ipv6-localhost ipv6-loopback fe00::0 ipv6-localnet ff00::0 ipv6-mcastprefix ff02::1 ipv6-allnodes ff02::2 ipv6-allrouters ff02::3 ipv6-allhosts 127.0.0.2 darkhelmet.edumate darkhelmet 10.0.0.22 db2workgroup db2workgroup [root][skroob] nslookup darkhelmet Server: 10.0.0.10 Address: 10.0.0.10#53 Name: darkhelmet.edumate Address: 10.0.0.22

  • XenServer: Editing clone configuration before boot

    - by Jeff Ferland
    Upon cloning a base image, I need to reconfigure basic settings. Regenerating the ssh host key, changing static IP assignments, setting the host name, etc. Because of the network setup, DHCP is not an option. That more or less rules out SSHing in with a predefined key or running a startup script since I can't provide the IP externally. I'd most like to mount the filesystem of the new machine on Dom0, but the lvm volumes are exported and it appears to be Bad Form to import them so the Dom0 machine can see them. What's your best suggestion for altering files in a cloned VM before boot? Must be non-interactive, and I'm going to guess out the gate that scripting access via xe console is not going to work well.

  • Sporadic '.Xauthority not writable, changes will be ignored' going from OSX -> Linux

    - by Kamil Kisiel
    Every now and then when users SSH from their OS X (Snow Leopard) workstation to one of our Linux hosts they receive the message: /usr/bin/xauth: ~/.Xauthority not writable, changes will be ignored Of course, their X forwarded applications will not work at this point. However, if they log out and log right back in again they do not get the message and everything works as expected. On their Mac they get their home directory via AFP. The Linux machines get it via NFS. Any ideas on what could be going on here?

  • What to consider if using triggers on tables in a sql-server merge replication

    - by Ice
    Hi, i am driving since some years a sql-server2000 merge-replication over three locations. Triggers do a lot of work in this database. i got no troubles. Now migrating these database to a brand new sql2008, i got some issues about the triggers. They are firing even if the merge-agent does his work. Is there anybody who has some experience with that kind of stuff on sql2008-server? Can anybody confirm that different behaviour to sql2000? Peace Ice

  • OS X Server App ail not accept login credentials

    - by user164113
    I cannot login to the server app and i know for sure all the login info is right. every time i enter my password the name window shakes to tell me it's invalid. I never post unless I'm out of ideas and I need it to be up so I can host my splash page tonight. i've spoken with "certified apple" specialists at some local mac stores and they are stumped too. Something is going on with the apache server, that's all i know for sure. I'll be monitoring this closely so any requests for info, etc. can be filled instantly. Thanks in advance. here's a few things i've noticed: I can ssh successfully into the server address as both root and admin. I've been fussing with the workgroup manager and could use guidance if that's where the problem lies. console shows this message repeatedly (org.apache.httpd[1890]) Exited with code: 1). Much appreciated, harry

  • Lock down SFTP access on OpenSolaris

    - by Simon
    Hi all, I have an OpenSolaris 2009.06 server and I'd like to enable a user to remotely change files in a specific directory, ideally via SFTP or FTP-via-SSH. This user does not yet have an account on the machine and I'd like to create it so it's as restricted as possible. Is there a canonical way of doing this? I know about OpenSolaris' role-based access control and authorizations model, but I figure it's a lot of work (i.e., a lot I can mess up) to really lock down a full-blown user account (prevent fork bombs, make sure there's really no other file in the file system which can be written to...). Any hint is greatly appreciated. Thanks, Simon
