  • How to install cURL with openssl on ubuntu server ?

    - by Hrishikesh Choudhari
    Hey, I am having a problem with cURL here. My localhost has curl with openssl enabled, and thus my php code works fine. On running phpinfo() I get the following -- curl cURL support enabled cURL Information libcurl/7.19.5 OpenSSL/0.9.8g zlib/1.2.3.3 libidn/1.15 However, on my other office server, curl does not have openssl support enabled. On running phpinfo() I get the following -- curl cURL support enabled cURL Information libcurl/7.20.1 zlib/1.2.3.3 How do I get openssl support for curl ? Both - openssl and curl - are installed on the office server as of now. I require immediate help. Thank you.

  • Why Buy Hardrives with storage server from a vendor?

    - by Mark
    Hi all, Im just browsing around at storage server's like the Dell MD100/ MD3000 and the Sun J4200 and although the storage server seems reasonable (approx $3000-$4000 AUD) the hard-drives that you buy to go along with them seems exorbitantly expensive. And I'm not sure why. Surely at most they are using good quality RAID level 7200rpm SATA hdd, but even then they are still charging almost 4 times the price. What is the advantage to buying these from them. I can see if one fails then the vendor replacing it is convenient. But at that price you could buy double the amount of hdd and just claim on warranty directly with the manufacturer. It would be much cheaper and you wouldn't be relying on someone else to fix your problems. Is this the case of "you don't get fired if you buy IBM?" mentality or is there some reason I'm not grasping here? Cheers Mark

  • Is there such a thing as "server sliding" (or similar), and if so, what is it?

    - by mahoke
    I am not a network engineer, but rather a translator, so I apologize in advance if this is a rather obvious question to some of you. Normally Google can answer my questions, but in this case I'm coming up blank. If I'm asking this in the wrong forum, please let me know. The text is talking about RADIUS accounting functionality. It says that when there are many (more than 200) authenticated terminals, if a command is issued to forcibly clear the terminals, "sliding to the next RADIUS accounting server may occur" -- the original text literally says "RADIUS accounting server-slide". I think I can basically understand what they are getting at in terms of meaning, but I would like to know whether this is the correct expression to use. I get the impression from my inability to find it simply by Googling that perhaps it's described differently in English.

  • CommunicationException when shutting down JBoss 4.2.2

    - by Brian
    I have deployed an application using JBoss 4.2.2 on a 64-bit RHEL5 server. Since there are other JBoss servers, I had to change some port configurations so that there would be no conflicts when starting the server. So right now I'm using ports-01 from the sample-bindings.xml file that came in the docs/examples/binding-manager/samples directory. In addition, below is a list of all the files I've edited to reflect the new ports: JBOSS_HOME/servers/default/deploy/jboss-web.deployer/server.xml: Changed Connector port - 8080 to 8180 Changed AJP 1.3 Connector port - 8009 to 8109 JBOSS_HOME/server/default/deploy/jbossws.beans/META-INF/jboss-beans.xml Changed 8080 to 8180 JBOSS_HOME/server/default/conf/jboss-service.xml: Changed 8083 to 8183 Changed 1099 to 1299 Changed 1098 to 1298 Changed 4444 to 4644 Changed 4445 to 4645 Changed 4446 to 4646 Changed 4447 to 4647 JBOSS_HOME/server/default/conf/jboss-minimal.xml: Changed 1099 to 1299 Changed 1098 to 1298 When I start the server (binding to localhost) everything is fine and I'm able to access the application. But when I try to shutdown the server I get the following error: Exception in thread "main" javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost [Root exception is javax.naming.CommunicationException : Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused]]] at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1562) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:634) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:627) at javax.naming.InitialContext.lookup(InitialContext.java:392) at org.jboss.Shutdown.main(Shutdown.java:214) Caused by: javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused]] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:274) at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1533) ... 4 more Caused by: javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:248) ... 5 more Caused by: java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:525) at java.net.Socket.connect(Socket.java:475) at java.net.Socket.(Socket.java:372) at java.net.Socket.(Socket.java:273) at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:84) at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:77) at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:244) ... 5 more Is there any other file that I need to change the 1099 to 1299, or am I missing some other step?

  • SQL Server Management Studio Reports: Why no open transactions?

    - by Sleepless
    On a server with several hundred user connections, when I open the SQL Server 2008 SP1 Management Studio report "Database - User Statistics", the result page shows the following results: Login Name: appUser Active Sessions: 243 Active Connections: 243 Open Transactions: 374 Still, when I open the report "Database - All Transactions" on the same DB, it doesn't show any connections ("Currently, there are no transactions running for [Database Name] Database"). What gives? Is this a bug in Management Studio? This is not the only report where this kind of behavious happens... Thanks all!

  • Is there a VNC server for mac with decent international keyboard support?

    - by Stephan
    Hi, I'm having trouble finding a VNC server for Mac OS X that allows me to connect from a Windows box with German keyboard layout. I've tried the built-in desktop sharing and several versions of Vine but all of them had problems with several keys. Does maybe anyone know about a working combination of a Mac OS X VNC server and Windows VNC client which properly supports a German keyboard layout on the client? Update: I don't think the Windows client is the problem, because I have no issues connecting to Linux boxes. And I've tried several different clients.

  • Server hard disk read speed and client download speed, is there a connection? [closed]

    - by Mywiki Witwiki
    Ok so a client's download speed is only as fast as a server's upload speed, and vice versa. Based on the answers to this post: Does upload speed depend upon download speed of the server? In other words, the data transfer rate between the two computers is only as fast as the speed of the "bottleneck". Let's pretend the two computers are in two different networks and both have 100Mbps internet connection. Ben wants a copy of a file in Mark's computer hard disk with 30Mbps read speed. Does this mean that Ben can download the file at a speed of around 30Mbps only, despite having an internet connection faster than 30Mbps?

  • How do I change the document root of a Linux Apache server?

    - by Daryl Spitzer
    I'm trying to learn how to configure an Apache HTTP server (with which I have no experience) someone else has setup in a VM running Ubuntu 8.04. I know the server is running, since I get "<html><body><h1>It works!</h1></body></html>" when I go to http://1.2.3.4/ (where 1.2.3.4 is the VM's IP number). I found apache2.conf and httpd.conf (among other files) in /etc/apache2/. httpd.conf is empty. I tried adding DocumentRoot "/home/username/temp" into /etc/apache2/httpd.conf and put some simple HTML in /home/username/temp/index.html. But when I reload http://1.2.3.4/ there's no change. Do I need to restart httpd to get it to accept the change to DocumentRoot?

  • Should I reinstall my production server from 32 bit to 64 bit if it has 16GB of RAM?

    - by Alexandru Trandafir Catalin
    I have a production server with 16GB of RAM that came with a 32bit CentOs installation. The website hosted on this server is increasing its traffic every day and I am having some MySQL trouble so I tried to check the MySQL configuration with mysqltuner.pl and gave me the following messages: [!!] Switch to 64-bit OS - MySQL cannot currently use all of your RAM *** MySQL's maximum memory usage is dangerously high *** *** Add RAM before increasing MySQL buffer variables *** So my question is: can I survive with the 32 bit? Or I will have to install the 64 bit OS? Thanks.

  • How to protect an OS X Server from an anautorized physical connection?

    - by GJ
    Hi I have an OS X 10.6 server, which I administer via SSH and VNC (via SSH tunnel). I can't leave it at the login window since then VNC connections are refused. Therefore I currently leave it logged with my user account. Since it doesn't have a monitor attached, it doesn't go into screen saver mode, which means it doesn't require a password to retake control. This means it is very easy for anyone connecting a keyboard/mouse and monitor to take control of the system. The screen saver password protection, which I can't get to activate, unlike the system's login window, is perfectly compatible with VNC connections. How could I prevent such direct access to the server without connecting a monitor and without blocking my ability to connect with VNC? Thanks!

  • The downsides of using nginx as a primary web server?

    - by FractalizeR
    Hello. I've seen millions of websites using nginx as a proxifying webserver working together with Apache. But I've seen very few servers running nginx only as their default webserver. What are the main downsides of such config? I can see some: Inability to use per-directory config files like .htaccess so every configuration change should be done to main server config file and requires server reload. But pecl htscanner can compensate them for php settings Unavailability of mod_php for nginx, which can be compensated by php-fpm for example. What are others? Why don't people just drop Apache and move to nginx or any other lightweight solution? May be, there are some special reasons?

  • In Djano, why do I get a 500 server error when browsing, but "python mysite.fcgi" from SSH works fin

    - by Jim
    If I browse to my site, I get a 500 "internal server error." However, if I SSH into my server and go to my site's folder and run "python mysite.fcgi" I see the HTML rendered fine. Obviously, something is wrong, but I'm not sure what. Here is my .htaccess file: AddHandler fastcgi-script .fcgi RewriteEngine On RewriteRule ^(media/.*)$ - [L] RewriteRule ^(static/.*)$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L] Here is my mysite.fcgi file: #!/usr/bin/python2.5 import sys, os sys.path.insert(0, "/kunden/homepages/34/[mydir]/htdocs/projects/django") sys.path.insert(1, "/kunden/homepages/34/[mydir]/lib/python/site-packages") os.chdir("/kunden/homepages/34/[mydir]/htdocs/projects/django/mysite") os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings' from django.core.servers.fastcgi import runfastcgi runfastcgi(["method=threaded", "daemonize=false"]) I'm setting this up on 1and1. It has been a pain, but I think I'm close.

  • How do I find out if mod_security is installed on my apache server?

    - by Haluk
    How can I find out if mod_security is installed on my apache server? I would also like to learn its version. I'm having some upload issues and I tried to disable mod_security using .htaccess. But that started producing 500 internal server errors. I read somewhere that depending on my mod_security version I might not be able to disable it using .htaccess. So I would like to understand if I have mod_security installed and what version it is. I'm on a centos 5 box. Thanks! UPDATE -1 xxxxxxxxxxxxx Does the below output mean I do not have mod_security installed? [root@u11 htdocs]# httpd -l Compiled in modules: core.c prefork.c http_core.c mod_so.c

  • What are the effects of the L root server now publishing DURZ?

    - by brent
    I'm curious what the actual effects of the L root server publishing DURZ today will be. On the nanog mailing list, someone said it's important to evaluate the systemic effects of root name servers publishing signed zones, even when not using DNSSEC. Meanwhile, RIPE's own published information on their changes to the K root server say there's no issue if your resolvers don't use DNSSEC. Can someone please clear this up? DNSSEC seems to be a messy, tangled web. If not enabling DNSSEC on my resolvers, do I have anything to worry about with the upcoming changes to the root servers?

  • How to estimate a server specifications for this particular system? [on hold]

    - by Alvaro Fallas
    I'm working in a college project and I'm supposed to specify the server's hardware to hold a system. The system is some kind of social network. And it is supposed to hold around 100 000 users the first year, also the system must be able to handle 1000 users working at the same time. It is the first time I'm asked to do something like this, so I hope you can give me a hand and help me because I feel a little lost. The system's data base is Mysql. I found some server configurations offered by Amazon Web Services, but I don't know which of them is the better for my system due to lack of experience Hope you can help me.

  • GF 3.0.1 + Virtual Server: www.myhost.com:8080/projectname-war => www.myhost.com. How?

    - by Harry Pham
    I need to change www.myhost.com:8080/myproject-war to www.myhost.com. This is what I try. In admin console in Glassfish 3.0.1, I create a http-listener-3 with port 9090 and address 0.0.0.0 (I want to have port 80, but got access-denied or some sort). I then create a virtual server call scholar, with Id=scholar, Hosts=${com.sun.aas.hostName}, Network Listeners: http-listener-3, Default Web Module=project#project-war.war(it is the only option from the drop down list since I only deploy 1 app). Then under Applications, I set the virtual server of the application to be scholar. Save and restart. I try localhost:9090, and expecting that it will load my project like as if I type localhost:9090/project-war. But it does not. I already set the Default Web Module, to be the project, why doesnt it load the project by default?

  • Does scheduling recycling app pool in IIS7 help the server conserve memory better?

    - by user29266
    Hello, I have a VPS (IIS7 with Win 2008) It's got: 40 websites and a SQL Server 2008 powering them with only 2 Gigs of RAM. None of the sites are mission critical, they are all just demos. I often have ram issues on the server because each site has does caching and generally uses a lot of memory. Would it make sense to set the application pools to recycle every 3 hours? I'm sure this would free up any memory leaks or processes left "hanging" Are there any other tips on this? Thank you very much!, Aron

  • Overwrite SOA expiry in a bind9 slave name server.

    - by Joachim Breitner
    I run a slave name server of a domain that I do not have full control over (i.e. changing the SOA is not possibly). The SOA specifies an expiry time of one week. For various reasons, I’d like to override that value on my specific slave server to something larger. Is there a way to do that? N.B: I know that for the refresh and retry fields, bind9 provides the options min-refresh-time, max-refresh-time, min-retry-time and max-retry-time to overrule the SOA, as mentioned in the documentation. For some reason this just does not inclucde expiry.

  • How can I change exim's DKIM and SPF for emails sent?

    - by 0pt1m1z3
    I've now spent 2 hours trying to figure out this issue and I am about to give up and go to bed. I've been having issues with Gmail rejecting emails from my VPS server because of false spam alerts (probably caused by lfd sending too many emails). So I changed my Exim config to send emails from a different IP (my VPS comes with 3) and that fixed the issue. I also enabled DKIM and SPF on my domains for added measure. But now, all my emails appear as ("From: Sender Name via server.domain1.com") where server.domain1.com is my VPS hostname. I previously had the same issue in Outlook and turning off "Set SMTP Sender: headers" solved that problem. But I believe adding the DKIM and SPF now makes Gmail add "via server.domain1.com" to my messages. How do I fix this? This is a typical header for a message (as it appears at gmail): Delivered-To: [email protected] Received: by 10.60.44.163 with SMTP id f3csp248622oem; Thu, 29 Mar 2012 21:23:18 -0700 (PDT) Received: by 10.50.106.200 with SMTP id gw8mr452788igb.10.1333081398523; Thu, 29 Mar 2012 21:23:18 -0700 (PDT) Return-Path: <[email protected]> Received: from domain2.com ([X.X.X.X]) by mx.google.com with ESMTPS id y1si810998igb.3.2012.03.29.21.23.18 (version=TLSv1/SSLv3 cipher=OTHER); Thu, 29 Mar 2012 21:23:18 -0700 (PDT) Received-SPF: pass (google.com: domain of [email protected] designates X.X.X.X as permitted sender) client-ip=X.X.X.X; Authentication-Results: mx.google.com; spf=pass (google.com: domain of [email protected] designates X.X.X.X as permitted sender) [email protected]; dkim=pass [email protected] DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=server.domain1.com; s=default; h=Date:Message-Id:From:Content-type:MIME-Version:Subject:To; bh=wF8bBRgh01EYg4t5DAeVPv1Ps906UVIeRnQCb/HvSYw=; b=k/Pg7lnrO+Ud/z1mOTv+O/3DiJzzQgyBhfIizIaFHM8tF/eNJt5P2k+9yQB224sxYstZIWwVRBJmiqvcM1QhARv1HWqWma0crppZ3JOn+LRHANan634OBi+58SIRA+gu; Received: (Exim 4.77) id 1SDTVE-0005HA-9Y for [email protected]; Fri, 30 Mar 2012 00:31:56 -0400 To: [email protected] Subject: Password Reset Request MIME-Version: 1.0 Content-type: text/html; charset=iso-8859-1 From: Sender Name <[email protected]> Message-Id: <[email protected]> Date: Fri, 30 Mar 2012 00:31:56 -0400 X-AntiAbuse: This header was added to track abuse, please include it with any abuse report X-AntiAbuse: Primary Hostname - server.domain1.com X-AntiAbuse: Original Domain - domain2.com X-AntiAbuse: Originator/Caller UID/GID - [507 504] / [47 12] X-AntiAbuse: Sender Address Domain - server.domain1.com

  • Why do I have no TTY on a basic Ubuntu 9.10 server install?

    - by pr1001
    I have reinstalled Ubuntu 9.10 Server several times on a bog standard 1RU server and each time I finish the install and reboot I see GRUB run and am then presented with a black screen. The machine is running just fine, as I am able to SSH in, but I can't see anything on the attached monitor. I have a simple LCD screen connected via VGA and a signal is apparently being output to it, as it doesn't go asleep. Looking at /var/log/syslog I see: Mar 24 14:57:44 bridge5 rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ] However, I later see: Mar 24 14:57:44 bridge5 kernel: [ 0.001368] console [tty0] enabled Any thoughts? Thanks!
