  • HTTPS in sub domain redirects to main domain

    - by Amitabh
    We recently bought a wildcard certificate and installed it for a domain. It works fine for the main domain but seems to not work at all for any sub domains. Whats happening is we can access the sub domains fine on HTTP, but whenever we try HTTPS for the same sub domain url we are redirected back to the main domain. So if I put up a test folder "httpstest" in a sub domain with a index.html file in it, the following happens mysubdomain.mywebsite.com/httpstest/index.html or mysubdomain.mywebsite.com/httpstest/ works perfectly fine with http:// but mysubdomain.mywebsite.com/httpstest/ or mysubdomain.mywebsite.com/httpstest/index.html does not work with https:// and redirects to the main domain.Any help on this is greatly appreciated. The site is not the main site used for setting up the VPS. It was added from WHM. Environment: We are on a Linux VPS. Cpanel 11.30.6 , Apache 2.2.22, PHP 5.3.13 The Virtualhost entry looks like: <VirtualHost xx.xx.xxx.xx:443> ServerName my-own-website.com ServerAlias www.my-own-website.com DocumentRoot /home/amitabh/public_html ServerAdmin [email protected] UseCanonicalName Off CustomLog /usr/local/apache/domlogs/my-own-website.com combined CustomLog /usr/local/apache/domlogs/my-own-website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User amitabh # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup amitabh amitabh </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup amitabh amitabh </IfModule> ScriptAlias /cgi-bin/ /home/amitabh/public_html/cgi-bin/ SSLEngine on SSLCertificateFile /etc/ssl/certs/my-own-website.com.crt SSLCertificateKeyFile /etc/ssl/private/my-own-website.com.key SSLCACertificateFile /etc/ssl/certs/my-own-website.com.cabundle CustomLog /usr/local/apache/domlogs/my-own-website.com-ssl_log combined SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown <Directory "/home/amitabh/public_html/cgi-bin"> SSLOptions +StdEnvVars </Directory> # To customize this VirtualHost use an include file at the following location # Include "/usr/local/apache/conf/userdata/ssl/2/amitabh/my-own-website.com/*.conf" </VirtualHost>` I guess I messed up the formatting big time. Any help on formatting and on the issue is great appreciated. Thank you. Update: I could not update the formatting here. I posted the same question in a linux forum . I will really appreciate any pointer on it.

    - by wu
    I know that as a sysadmin you can contribute to opensource projects such as a Debian and Fedora. Joining their infrastructure groups and help with administration.

  • Problems creating service using sc.exe

    - by Shoko
    I have this command to create a service: sc create svnserve binpath="\"C:\Program Files (x86)\Subversion\bin\svnserve.exe\" --service --root C:\SVNRoot" displayname="Subversion" depend=tcpip start=auto obj="NT AUTHORITY\LocalService" Unfortunately, it seems not to work, even though the syntax is correct. When I run it, I get the usage instructions (which I guess is a way of telling me that I've supplied incorrect arguments, although I have no idea what incorrect argument I might have supplied). Can anyone help me out of my difficulty? Thanks!

  • What's a good Text Expander software for windows?

    - by chris.w.mclean
    What's a good text expander out there for windows? Ideally it needs to work w/ MS Word, needs to be configurable in how it gets triggered, (i.e. the string hdt when followed by a space gets transformed into Help Desk Ticket, but hdt gets ignored). And needs to have an import option where a large list of tags & expansions can be loaded. Plugins for UltraEdit/Notepad++ would also be acceptable.

  • Insert total number of slides in powerpoint 2007

    - by Bob Rivers
    Hi, Is it possible to insert to total amount of slides in a powerpoint footnote? I'm looking for an automated way. Of couse that I could edit the footer and put it manually, but, if I increase/decrease it, I would be necessary to adjust it. And this is something that we always forget. The help at MS explains how to do it manually. I can't believe that powerpoint doesn't have it... TIA, Bob

    I know Ghost and Clonezilla aren't able to build images of a system while the system is running(Without Rebooting).

Would appreciate anwsers, since I'm one step away from building a Clonezilla test enviroment and this will just help on my decision. Thank you.

  • Problem with several USB devices on Windows XP. How to diagnose USB device?

    - by Lukasz Baran
    Hello All, Recently I've bought some electronic devices (like e.g. Sony Ebook reader PRS-600 or HP PDA IPaq) which are connected to PC using USB ports. These devices have own batteries and they are recharged using USB. However, I am experiencing a problem with Ebook Reader and the similiar thing happens with my PDA (but in this case it's more rare). Sometimes, I am unable to make it start recharging, when it's connected to USB port. The LCD diode on my Reader lights up and the icon in the system tray appears. They both indicate that the device has been connected. However, the device should start recharching and it should appear on Windows XP as a 'explorable' device (just like pendrive it offers some HDDs). None of these happens:( This problem appears on two PCs - desktop and laptop. Both have Windows XP SP3 installed. And what's interesting and surprising to me is the fact that these devices sometimes work without any problems. I mean, I just plug them in and they work properly. Besides that, there are some computers (I have tested a variety of possible conditions) on which the problem does not appear! I am confused and, on the other hand, determined to find out what is the real cause of such strange behavior. Maybe I'm wrong but I always assumed that I'm using deterministic machines, but the described situation makes me feel like I was dreaming:) And that's why I'm asking you here. Are there any tools that could help me diagnose USB ports? Or maybe anyone knows the solution? I have a lot experience with low level programming (mostly from the times of MS-DOS applications), but I'm not an expert when it comes to WinXP technology. If this was a problem with network connection, I would know what to do - I know how to track network traffic, but with USB ports I feel powerless. I have a feeling that the problem may lie in a way WinXP handles USB devices. Personally, I hate auto-discovery and P'n'P features available in Windows. I know that some of may suggest to move to Linux or other *Nix system. Unfortunately, I have to use WinXP in my professional life, so it's rather impossible. Besides that, I don't consider XP as a total disaster. Any help from you will be appreciated!

  • Building \ installing PHP

    - by Jony
    I've followed this guide: http://www.phamviet.net/2012/06/03/centos-6-2-compile-php-5-4-2-from-source/ It all works as it should, but when I'm done and I type 'service httpd restart' following by 'php --version', it still displays the old 5.1.6 PHP version.

  • route http and ssh traffic normally, everything else via vpn tunnel

    - by Normadize
    I've read quite a bit and am close, I feel, and I'm pulling my hair out ... please help! I have an OpenVPN cliend whose server sets local routes and also changes the default gw (I know I can prevent that with --route-nopull). I'd like to have all outgoing http and ssh traffic via the local gw, and everything else via the vpn. Local IP is 192.168.1.6/24, gw 192.168.1.1. OpenVPN local IP is 10.102.1.6/32, gw 192.168.1.5 OpenVPN server is at {OPENVPN_SERVER_IP} Here's the route table after openvpn connection: # ip route show table main 0.0.0.0/1 via 10.102.1.5 dev tun0 default via 192.168.1.1 dev eth0 proto static 10.102.1.1 via 10.102.1.5 dev tun0 10.102.1.5 dev tun0 proto kernel scope link src 10.102.1.6 {OPENVPN_SERVER_IP} via 192.168.1.1 dev eth0 128.0.0.0/1 via 10.102.1.5 dev tun0 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 1 This makes all packets go via to the VPN tunnel except those destined for 192.168.1.0/24. Doing wget -qO- http://echoip.org shows the vpn server's address, as expected, the packets have 10.102.1.6 as source address (the vpn local ip), and are routed via tun0 ... as reported by tcpdump -i tun0 (tcpdump -i eth0 sees none of this traffic). What I tried was: create a 2nd routing table holding the 192.168.1.6/24 routing info (copied from the main table above) add an iptables -t mangle -I PREROUTING rule to mark packets destined for port 80 add an ip rule to match on the mangled packet and point it to the 2nd routing table add an ip rule for to 192.168.1.6 and from 192.168.1.6 to point to the 2nd routing table (though this is superfluous) changed the ipv4 filter validation to none in net.ipv4.conf.tun0.rp_filter=0 and net.ipv4.conf.eth0.rp_filter=0 I also tried an iptables mangle output rule, iptables nat prerouting rule. It still fails and I'm not sure what I'm missing: iptables mangle prerouting: packet still goes via vpn iptables mangle output: packet times out Is it not the case that to achieve what I want, then when doing wget http://echoip.org I should change the packet's source address to 192.168.1.6 before routing it off? But if I do that, the response from the http server would be routed back to 192.168.1.6 and wget would not see it as it is still bound to tun0 (the vpn interface)? Can a kind soul please help? What commands would you execute after the openvpn connects to achieve what I want? Looking forward to hair regrowth ...

  • Getting gvim to show unicode

    - by Rook
    How to get GVim (v. 7.3. on Windows XP, if that matters) to show Unicode characters? Something along the lines of http://vimcasts.org/episodes/show-invisibles/ (search for listchars to see the little triangle I'm trying to get). I'm using set encoding, set fileencoding, and set fileencodings, all to utf-8, if that helps. I know it must be something simple, but nevertheless, here I am, stuck. Help.

  • Best software to convert video to a different aspect ratio for various screensizes

    - by facepalmd
    I sometimes get .mp4 and other video formats whose aspect ratio is clearly off What apps do you use to reconvert such videos to an aspect ratio better suited to to fit either a regular desktop or LCD screen size? Hopefully with little or no loss of audio/video quality Any instructions on best settings to use would be very welcome. I have so far mostly used vlc which came off with less-than-ideal results. Thanks for any help you can offer.

  • how do I start GIT daemon automatically under CentOS 4.8 ?

    - by ck2
    Apparently my server is running CentOS 4.8 with Cpanel uname -a 2.6.9-023stab048.6-enterprise #1 SMP MSK 2008 i686 i686 i386 GNU/Linux cat /etc/redhat-release CentOS release 4.8 (Final) I'd prefer to install it as a service but I cannot seem to install "yum git-daemon" there is no package available for CentOS 4.8 (when I try to include another repos for it I get too many dependency failures) So what's the easiest way to just start it?

  • Buffer requests in nginx while a symlink switches on backend

    - by Quintin Par
    In a release deployment I would like to buffer client requests that come to nginx(in reverse proxy) mode to be buffered for possibily 1-2 seconds while a pdsh request is sent to switch symlinks on the back end server to /var/www/html/current . After the switch is complete, I would want to release the buffering while avoiding a herd clash. Is this possible in nginx? Can someone help? Edit: The idea is not to loose requests and from nginx forums I've come to know that retries can sometimes results in CPU spins
