  • Firewall issue with multiple SIP PROXY / REGISTRAR servers

    - by MikeBrom
    Hi We have a pair of Internet-facing SIP PROXY/REGISTRAR servers (for resilienced and load-balancing). When a SIP phone registers, it will be handled by one of the REGISTRAR servers (round-robin DNS) - and since this registration is renewed, the firewall port/address translation is maintained. Therefore, when a call is to be sent back to the phone the INVITE message passes successfully through the firewall. However, it is likely that the phone may register with one of the two servers, but the INVITE may come from the other. In this situation, the call fails since there is no translation in place on the firewall. Is there a feature in the SIP protocol to facilitate this? Any other ideas? As our traffic grows, we will no doubt end-up with more than two servers - so the problem will escalate. Thanks, Mike

  • Remote logging for multiple Apache virtual hosts using syslog-ng

    - by James
    I'm running a couple Apache web servers that each have 4-8 separate virtual hosts on each of them. I'm trying to setup a dedicated log server that stores each virtual host access and errors logs in a separate directory for that virtual host. For example on the logging server, /var/log/remove/10.0.0.2/virtualhost1 contains access_log and error_log /var/log/remove/10.0.0.2/virtualhost2 contains access_log and error_log /var/log/remove/10.0.0.3/virtualhost3 contains access_log and error_log and so on... Right now I have it split up by host but I can't figure out how to do it additionally by virtual host. Here are the relevant lines from the logging server's syslog-ng.conf source r_src { tcp(ip("0.0.0.0") port(5140)); }; destination r_all { file("/opt/splunk/logs/$HOST"); }; log { source(r_src); destination(r_all); }; Any help would be appreciated. Thanks!

  • In between multiple tabs, how to use Vimperator to open a tab after current one

    - by Mehrad
    If you're a Firefox user you know that if you have 10 tabs open and say you're in the tab #5. If you open a new tab which will become #11 in order and search something, after you finish and close this #11 tab Firefox will direct you the the last active tab you were in which is #5. Using Vimperator You won't get the similar effect. In the same scenario, while you're in tab #5 you can go t and search for something which will lead to opening a tab at #11. Now you press d and where you are now ? #10 and you need to ctrl+p all the way back to #5. So in this case I am looking for one of these solutions. to be able to open a tab straight after the current tab (which closing it will capital D will put me back to my active tab) a way to close a tab and being brought back to the last active tab that I worked on. Will appreciate it if somebody got a solution for this. thanks

  • One Mac computer with multiple network connections?

    - by Kyle Lowry
    I have a Mac (OS X 10.5) that I would like to connect to a dedicated/isolated Internet connection (one that is not connected to the LAN), and a LAN. The LAN is set up with its own, separate, Internet connection which is shared by several dozen computers (and is quite slow). I want to set it up so that the Mac uses its own dedicated Internet connection (on a different account with a different company) for its Internet access, but can still access the local area network as well. How can I configure the Mac & the network to allow this?

  • Sync my files across multiple computers

    - by EnderMB
    I do a lot of work on my home computer, ranging from programming, writing stored procedures and writing documentation and reporting. A lot of this work is university related and constantly swapping files across several computers is annoying at best. I have a large final-year project coming up and I'm going to be sharing this work amongst home and university and require some kind of online storage that provides version control for my programs, as well as my Word documents, PDF's and saved academic papers. Are there any good solutions for my problem?

  • Outlook Multiple POP3 Accounts

    - by Peter
    Dear all, I just created a new POP3 account in my 2003 Outlook. I checked the settings and the Inbox-Outbox are working well. However if I send from my standard Outlook POP3 account a mail to my Second one I do not receive it. I receive the message: 550-Mailbox unknown. Either there is no mailbox associated with this 550-name or you do not have authorization to see it. 550 5.1.1 User unknown Does anybody know how to fix this. Many thanks.Peter

  • Single Form with Multiple Dynamic Buttons

    - by John Reilly
    I've spent hours/days trying to figure this out and now I'm completely perplexed so I thought I'd give stackoverflow a try. I'm (a newb) working in Java/JSP using Eclipse hosting on Google App Engine trying to develop an app for a volunteer organization I'm a member of. Rather than embarrass myself by showing my current code I'd love just a nudge in the right direction. I have a form (which doubles as a report basically) showing "people" grouped under the "task" they are currently working on. I would like to select multiple people from multiple tasks and reassign them to another task e.g. Bill and Jane are Gardening, Jeff is Painting. I want to select Jane and Jeff (all people have an associated checkbox in the form) and re-assign them to Sweeping (which is a task on the form but has no people assigned to it yet). Ideally, the re-assignment to Sweeping would be via a Sweeping button (each task would have a dynamically-created task button) that would pass the "Sweeping" value to a servlet along with an array or list of people whose checkbox has been checked. The servlet would handle the request (creating an Assignment "object/entity" with timeStamp, personId, taskId) and then re-direct back to the form/report which would then repaint with the current tasks/people generated from the Assignments class in the datastore. All the tasks are user-defined and retrieved from the database when building the form. Ditto the people. I've been trying to keep the jsp for presentation and the servlets for the processing but I'm no purist and would just like to get unstuck. Many thanks in advance for your assistance.

  • ntop to analyse bandwidth usage on multiple ASA 5505

    - by dunxd
    I have set up a netflow server at our data centre, which is connected via VPN to ~40 remote offices using Cisco ASA 5505. The aim is to analyse usage data and find out exactly how the remote connections are being used. I followed through http://techowto.files.wordpress.com/2008/09/ntop-guide.pdf to set up ntop and https://supportforums.cisco.com/docs/DOC-6114 to set up the ASAs. I can see from the Plugin Netflow Statistics page that netflow packets from my ASAs are being received - the counter is increasing. However, I am not seeing any breakdown on the Global Traffic Statistic page after switching to the Netflow interface. I'm just seeing a pie chart showing 100% traffic for eth0. The interfaces and documentation are a little hard to follow so I am not sure I have got things configured correctly. When setting up my NetFlow-device.2 I can specify Virtual NetFlow Interface Network Address - the web UI says This value is in the form of a network address and mask on the network where the actual NetFlow probe is located. is this a Network address (e.g. 192.168.0.0/24) or an actual host IP address (192.167.0.1/24)? If that should be a network address, is this the network in which one of my ASAs is or the network in which my ntop server is? If a host IP address, is this the IP address used by eth0 on my ntop server, the IP address of an ASA, or something else? Do I need a separate virtual interface for each ASA I am collecting netflow data from? Any guidance would be greatly welcome.

  • Setup staging with multiple SVN

    - by Kapil Sharma
    We are a startup, setting new environments for product to be released soon. Planned server structure with planned release flow is as shown in below image It ideally have a local server (or Staging server, shown in green) in local office, without public IP address and Production Server (Red) at Amazon EC2. Both local and production server have there own SVN copy. Management here want to update production server with production SVN and without providing its access to developers (including freelancers/contract employees). So for developers, there is a Local SVN on local server. Another purpose of local SVN to keep a copy of code on local server, which is under our direct control. Although there are some technical concerns like how will code at local server will be updated from local SVN and commit on production SVN but bigger question is, is that structure correct? Major requirement remain don't provide production SVN access to developers. What are other possible options to achieve that? Another minor question, if suitable here, if above structure is correct, is it possible for a SVN checkout to get updated from one SVN (Local SVN) but commit to other (Production SVN)? If yes, How? edit An answer has been accepted but for bounty, I'm still looking for answer Is that structure correct? Its pros/Cons? Technical solution is already provided by accepted answer.

  • JPA - Performance with using multiple entity manager

    - by Nguyen Tuan Linh
    My situation is: The code is not mine I have two kinds of database: one is Dad, one is Son. In Dad, I have a table to store JNDI name. I will look up Dad using JNDI, create entity manager, and retrieve this table. From these retrieved JNDI names, I will create multiple entity managers using multiple Son databases. The problem is: Son have thousands of entities. It takes each Son database around 10 minutes to load all entities. If there is 4 Son databases, it will be 40 minutes. My question: Is there any way to load all entities and use them for all entity manager? Please look at the code below For each Son JNDI: Map<String, String> puSonProperties = new HashMap<String, String>(); puSonProperties.put("javax.persistence.jtaDataSource", sonJndi); EntityManagerFactory emf = Persistence.createEntityManagerFactory("PUSon", puSonProperties); PUSon - All of them use the same persistence unit log.info("Verify entity manager for son: {0} - {1}", sonCode, emSon.find(Son_configuration.class, 0) != null ? "ok" : "failed!"); This is the actual code where the loading of all entities begins. 10 mins.

  • Multiple Java Versions

    - by user327486
    There are few applications which use Java 1.6.2x , few 1.7.1X and other uses 1.7.4X versions. Since we decided to push all three applications to the user .How to make the applications to use its particular version. There are few web based apps and enterprise apps which requires only a specific set of java versions which is creating issues. Os : Win 7 IE - ver 8 Work around In Progress : Trying to apply a batch file for each app to set the require java version path , but its not the required solution. Do we have any generic way which automatically maps to its required java version , instead of running batch file for each application. Looking forward your valuable suggestions.

  • How to automatically save sessions with multiple windows in FireFox

    - by Matthew Talbert
    I've used primarily FF's built-in session management until recently. Now my needs have become more sophisticated. What I want is to be able to have two windows, one with a fixed set of tabs (approximately 5) and the other with "automatic save". That is, when I start FF, I want 1 window to open with my 5 tabs, and another to open with whatever I had when I shut down FF. I've installed "Session Manager", but I can't seem to get it to do what I want. It will save one window, but when I close one window, it removes that one from the session. Any suggestions to do this with either Session Manager or another plugin would be great.

  • lighttpd: weird behavior on multiple rewrite rule matches

    - by netmikey
    I have a 20-rewrite.conf for my php application looking like this: $HTTP["host"] =~ "www.mydomain.com" { url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/my_app.php" ) } I want to be able to put the webserver in kind of a "maintenance" mode while I update my application from scm. To do this, my idea was to enable an additional rewrite configuration file before this one. The 16-rewrite-maintenance.conf file looks like this: url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/maintenance_app.php" ) Now, on the maintenance page, I have a logo that doesn't get loaded. I get a 404 error. Lighttpd debug says the following: 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.349) -- sanatising URI 2012-12-13 20:28:06: (response.c.350) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (mod_access.c.135) -- mod_access_uri_handler called 2012-12-13 20:28:06: (response.c.470) -- before doc_root 2012-12-13 20:28:06: (response.c.471) Doc-Root : /www 2012-12-13 20:28:06: (response.c.472) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.473) Path : 2012-12-13 20:28:06: (response.c.521) -- after doc_root 2012-12-13 20:28:06: (response.c.522) Doc-Root : /www 2012-12-13 20:28:06: (response.c.523) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.524) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.541) -- logical -> physical 2012-12-13 20:28:06: (response.c.542) Doc-Root : /www 2012-12-13 20:28:06: (response.c.543) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.544) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.561) -- handling physical path 2012-12-13 20:28:06: (response.c.562) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.618) -- file not found 2012-12-13 20:28:06: (response.c.619) Path : /www/img/content/logo.png, /img/content/logo.png Any clue on why lighttpd matches both rules (from my application rewrite config and from my maintenance rewrite config) and concatenates them with a comma - that doesn't seem to make any sense?! Shouldn't it stop after the first match with rewrite-once?

  • Multiple Servers + One MailServer

    - by theomega
    Hy, I got several Linux-Servers (running Debian) where different services run: Database-Servers, Webservers, Applicationsservers, Tools and so on. All Servers are connected to the same internal network. There is also one special Server which is the Mail-Server: All Mailaccounts are stored on this server, it is also the outbound Mailserver for all the other servers. I want all Mails for all servers to get saved on the Mailserver. For example if an cron-job fails on one of the web-servers the mail should not be delivered to the local user but instead to the Mailserver so I get a centralized place for mail storage. How do you set up this scenario? My current setup is: Using postfix as MTA on the Mailserver and using ssmtp on all the other servers. SSMTP is configured to send the mails to the Mailserver. The Mailserver is configured to allow the whole internal network to relay mails using itself. Is this the right way to choose? I also thought about setting up a MTA (postfix) on every server and configure it somehow to forward the mails. What would be the advantage of this solution?

  • List repositories from multiple projects in Trac using mod_python

    - by Steffen Eriksen
    Currently working on a customized webpage that shows the available projects I have in Trac (1.0.1). I am using mod_python to connect the trac interface. I found a standard page for this, but it didn't show listing of repositories. The page showed some variables to link to the different projects, but I can't find variables to the different repositories inside the projects. I have set up the webpage from reading this: http://trac.edgewall.org/wiki/TracInterfaceCustomization (under Site Appearance) Short summary; editing ../conf.d/trac.conf: PythonOption TracEnvParentDir /parent/dir/of/projects PythonOption TracEnvIndexTemplate /path/to/template And making a template file I can edit at /path/to/template: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:py="http://genshi.edgewall.org/" xmlns:xi="http://www.w3.org/2001/XInclude"> <head> <title>Available Projects</title> </head> <body> <h1>Available Projects</h1> <ul> <dl> <li py:for="project in projects" py:choose=""> <a py:when="project.href" href="$project.href" title="$project.description">$project.name</a> ## <dd> WANT TO ADD CODE HERE! </dd> <py:otherwise> <small>$project.name: <em>Error</em> <br /> ($project.description)</small> </py:otherwise> </li> </dl> </ul> </body> </html> So... The code I want to add is something like: <dd py:for="repos in project.repository" py:choose=""> <a py:when="repos.href" href="$repos.href"> $repos.name</a> </dd> I can't figure out where to add the variables, or if there already exists some variables I can use. After searching through the files it seemed like main.py had something to do with the variables (/usr/local/Trac-1.0.1/trac/web/main.py), but at first look it didn't seem easy to just add more variables. Is there a simple way to find the rest of the variables ? And how hard is it to add more variables? Will it perhaps be easier to do this an alternative way ? All I need is to link to the repositories dynamically

  • SSD with multiple partitions - disk life implications

    - by Nicolas Webb
    Each block on a SSD has a finite number of writes. This is mitigated on modern drives by "spreading" the writes around as you use the drive. I'm wondering if you partition a SSD into several partitions (a Mac using Boot Camp, for example) if this measure is defeated somewhat - can the writes be spread across the entire drive? Or are they contained strictly within the partition boundaries? Any SSD controller engineers here :)?

  • Permanently mount multiple directories from different disks under /

    - by piotrek
    I have SSD and HDD. Some directories like /var, /srv and /tmp should be on HDD, while /boot, /usr and /lib on SSD. But do I have to create separate partition for every single directory? I want to have 2 or so partitions. One for each disk and distribute directories as needed. Is it possible and how? I've heard about symlinks, mount --bind, mhddfs but: symlinks are treated differently by tools like cp, so I'm not sure if it's safe to have main system directories symlinked I have no idea how can I use mount --bind or mhddfs in fstab

  • Do Hyper-V guests see multiple CPUs (sockets) or multiple CPU cores when assigned more than 1 vCPU?

    I have SQL Server 2008 Express running on Hyper-V based virtual machine with two vCPU-s. I've just been reading up on SQL Server 2012 Express and noticed that it's CPU is "Limited to lesser of 1 Socket or 4 cores" (http://msdn.microsoft.com/en-us/library/cc645993(v=SQL.110).aspx) My question is how do the SQL Server 2012 limits on CPUs/Cores translate into vCPU-s? Are they "processors" or are they "cores"?

  • Monitoring multiple sites on a single server using OpsView

    - by Kev
    We have several web servers. On each of these servers there can be ~250 web sites. I need to add a HTTP check for each site on each server. Each site has a reserved host header that we know can always be resolved in the format of: w10000.hostchecks.mycompany.com w10020.hostchecks.mycompany.com w11992.hostchecks.mycompany.com ..and so on.. What I want is for there to be a master ping check on the web server's main IP address and then separate HTTP checks for each of the sites on the server. If the master ping test fails then I want the HTTP tests to cease until the master ping check goes OK. I had a stab at this and tried do the following: Create a parent host that does a ping check on the server's main ip address (e.g. server is named WEB0001). For each of the sites that reside on WEB0001: Create a separate Host with a Primary Hostname of wXXXXX.hostchecks.mycompany.com Make WEB0001 the parent host Add a monitor (HTTP check to a special url that is mapped into each site using a virtual directory: H- $HOSTADDRESS$ -u /__hostcheck/IsAlive.aspx -w 5 -c 10 -p 80 However I find that if I down the parent server (WEB0001) the http checks seem to continue. Am I going about this completely the wrong way?
