  • How should flushing be handled in a doctrine EntityManager instance shared across different services in symfony2?

    - by Jbm
    I have defined several services in symfony 2 which persist changes to the database. These services have the doctrine instance as one of their dependencies: a.given.service: class: Acme\TestBundle\Service\AGivenService arguments: [@doctrine] If I have two different services and both of them persist objects through the EntityManager, which is obtained like this from the doctrine instance: $em = $doctrine->getEntityManager(); Would all services always share the same EntityManager? If so, how should I handle flushing if I wanted to handle all the changes in a single transaction? I have checked this: http://docs.doctrine-project.org/projects/doctrine-orm/en/2.0.x/reference/transactions-and-concurrency.html and it explains how to handle different transactions in a request, but I want to achieve the opposite, which is having different changes in different services handled as a single transaction. Is there a better approach to handle multiple changes in different services? For now my best bet is having a front-end service in charge of calling the other services and doing the flushing afterwards. Backend services would persist objects but would not do any flushing.

  • rdesktop remote connect windows server 2012r2, device redirection doesn't work

    - by user197677
    I use rdesktop to connect to a windows server 2012r2 from my linux box. it worked well. but it doesn't work when I redirected my local directory /home to the server. My command: rdesktop -a 24 -r disk:home=/home -u test 192.168.1.110 I could connect to the Windows server. but I cannot see the directory in my remote computer. Running net use x: \\tsclient\home' works when I connect to windows 7, but it yields this error in windows server 2012r2: system error 87 has occure the parameter is error I have no idea what to do. I have turned off the firewall and deployed the RemoteFX to enable device redirection.

  • CentOS not allowing remote MySQL connections

    - by nd8ad
    When assigning a user from a remote IP to connect to a database it is saying that it's failing to connect. It is also failing to connect with root so something is wrong. Bind IP is off and I have also tried disabling iptables, still no dice. Port 3306 is forwarded. I'm running on Centos 5.6, using phpmyadmin, but I have also tried to assign the user via the commandline and create a new database, still not working. Been googling and troubleshooting for hours now, no dice.

  • Resolving Domainnames differently for different services

    - by mlaug
    Some time ago we had an issue with our network infrastructure and php with curl. Our Network infrastructure is fairly simple. LoadBalancer/Firewall = 5 servers The Domainname of our website is set to the ip of the Loadbalancer, of course. But calling curl from one of the servers did result in a timeout. It appears that a server could not call for its own domain it is serving. So we had to set the domains via /etc/hosts to the sever itself. But now We have implemented a Varnish in front of the Loadbalancer, which we want to automatically purge, once a change on a page happens. So now we need to call the domain www.example.com/url_to_purge. Sadly this call what be resolved to the server itself instead of the varnish, because of the /etc/hosts entries. So now I am wondering, if you could resolve domain names differently for different services :)

  • How come Core i7 (desktop) dominates Xeon (server)?

    - by grant tailor
    I have been using this performance benchmark results to select what CPUs to use on my web server and to my surprise, looks like Core i7 CPUs dominates the list pushing Xeon CPUs into the bush. Why is this? Why is Intel making the Core i7 perform better than the Xeon. Are Desktop CPUs supposed to perform better than server grade Xeon CPUs? I really don't get this and will like to know what you think or why this is so. Also I am thinking about getting a new web server and thinking between the i7-2600 VS the Xeon E3-1245. The i7-2600 is higher up in the performance benchmark but I am thinking the Xeon E3-1245 is server grade. What do you guys think? Should I go for the i7-2600? Or is the Xeon E3-1245 a server grade CPU for a reason?

  • Installer Vs. Desktop application

    - by Ram
    hi, I was just wondering why do we need installer programs to create setups? We can create a desktop application which will do registry changes, registration of assembly, creation of config files and all. Why dedicated installers are there? Do they serve any other purpose or task that a desktop application cannot do?

  • git rebase, keeping track of 'local' and 'remote'

    - by Benjol
    When doing a git rebase, I often have difficulty working out what is happening with the 'local' and 'remote' when resolving conflicts. I sometimes have the impression that they swap sides from one commit to the next. This is probably (definitely) because I still haven't properly understood. When rebasing, who is 'local' and who is 'remote'? (I use P4Merge for resolving conflicts)

  • need help setting up a VPN for remote computer connection

    - by Chowdan
    I am on a low budget right now. I am currently in the process of starting a computer company. I am in need of a VPN network so I can run Dameware tools for working on customers/partners computers remotely. I will be working with Windows and some Apple and linux machines. I have desktop with an AMD Phenom II 965BE(currently running stable at 3.8Ghz) processor with 8 GB of ram and a radeon hd 6870(i know graphics aren't too useful) and about 1.5TB of HDD space. I am attempting to create a network out of my office based all on one machine that would also be secure for me to remotely connect to my partners computers so when they have issues I would be able to connect and do the diagnosing and repairs remotely. What types of servers besides a VPN server would i need to create this? I have access to all Microsoft products so I can run Windows Server 2012, Windows Server 2008 R2, or any other Microsoft Software. thanks for the help all

  • Emacs doesn't use ~/.ssh/config when accessing files on a remote machine

    - by Yotam
    I have a fresh install of arch Linux. I've installed Emacs from the rpos, and my home directory is mounted from a separate partition. I have old settings I've used on my ~/.ssh/config along with authentication keys I've regularly used before. Now, when I try to connect to a remote machine using Emacs, Emacs asks for my password and uses the wrong username. Clearly, Emacs doesn't access my config file. When I try to ssh or scp directly to the machine, things work fine. What do I need to update?

  • Regaining access to Linux server after SSH service dies?

    - by GigaWatt
    I recently ran into an issue with a VPS where the SSH service crashed, leaving me unable to connect to the machine. The other services were up and running; only the SSH service died. I managed to resolve the situation with a reboot from the VPS control panel, but the incident got me thinking: Assuming: I don't have physical access to the machine I have no server control panel access or means of rebooting the server All other system services are still functioning Then how could I recover from the SSH service dying?

  • RAID striping on a desktop machine

    - by Blazemore
    I currently have a 120Gib SSD which is pretty fast for things like game loading times and video editing. However, I was wondering about getting another identical drive and hooking it up with a striping RAID array in hardware (I boot multiple operating systems). This would have the dual benefits of providing a larger logical drive, while also providing greater performance. However, I have a few questions: What kind of performance increase can I expect to see with a pair of good quality SSDs? How expensive is a quality desktop RAID controller? Will the controller present the OS with a single logical drive? Does this mean I can still partition it and multi-boot? Basically, can I treat the RAID controller as "a hard drive" at the OS level?

  • SBS 2008 - Blank desktop while installing

    - by Sandokan
    I'm trying to install SBS 2008 Standard Ed on a VMware Workstation 8. The installation runs fine up until some point where the desktop becomes completely blank. The server is still running and responds to CTRL+ALT+DELETE and CTRL+ESC, but there are no icons and no explorer-bar. I have tried to install it twice now and each time it comes to a halt at the same spot. Starting Taskmanager and launching explorer.exe only brings up the filemanager. Anyone have a clue to what it could be?

  • running a python script on a remote computer

    - by Richard
    Hello all, I have a python script and am wondering is there any way that I can ensure that the script run's continuously on a remote computer? Like for example, if the script crashes for whatever reason, is there a way to start it up automatically instead of having to remote desktop. Are there any other factors I have to be aware of? The script will be running on a window's machine.

  • Dumb Terminals, Virtual Desktop

    - by user67714
    I need some help in setting up a dumb-terminal type concept for Windows machines. We have a computer lab with 40 computers, all of them are ageing. Unfortunately, we don't have enough funds to get all of them replaced. On the other side, we have very powerful rack servers which are quite underutilized. I was thinking of a solution which would enable those lab computers to use the rack servers. Remote desktop is an option, but I wanted something that is more transparent to the end user. Are there any free or low cost solutions for such an scenario?? Thanks

    - by Rayfloyd
    I'm trying to set up MSSQL 2012 for a school project and I need to be able to connect to it remotely as my teammates will also be working on it. I did a clean install of SQL Server 2012 Express. Knowing I can't connect remotely straight off, I tweaked the settings that needed tweaking according to the internet. What I did 1.Made sure remote connections were allowed 2.Enabled TCP/IP 3.Removed 0s from Dynamic ports and set 1433 in TCP Port 4.Enabled Named Pipes 5.Created Outbound and Inbound traffic rules in the firewall for TCP port 1433 and UDP port 1434 6.Port forwarded 1433 to my "server" and 1434 too 7.made sure I was pingable 8.SQL Server authentication is enabled 9.I have restarted my computer so that changes to the config are saved So whenever I try to connect using management studio on another computer than the server using myusername.dyndns.org\SQLEXPRESS I get error 26 I have been searching for different solutions for 3 hours with no luck.

  • Recommend a desktop app to monitor port 80 on servers

    - by busyone
    Hello, I did some googling but was unsuccessful, so I am posting here. I am looking to get an app (preferably free/open source) to monitor my servers on port 80 that would send me an email/text when some predefined timeout triggers. I could probably write something in VB to do this but i am burried with projects, why reinvent the wheel. I know there are services out there that want you to pay $5/month to do so, I was thinking about a Windows app that would sit on my computer and simply monitor predefined list of IPs on port 80. Thanks!

  • NetUserAdd() to Remote Desktop Group?

    - by Brett Powell
    Is there anyway to give a newly created user from NetUserAdd() remote desktop access and/or administrative rights? I know it is possible, at least for Remote Desktop, and I have been reading through the MSDN but nothing seems to hint at what is required to be set for it to work.
