  • nginx + varnish + apache differente IPs in VirtualHost Apache

    - by zeusgod
    Hi, My idea is put NGINX as proxy to redirect to Varnish (cache static content) and then proxy to apache with a lot of VirtualHost in different IPs. My problems is that I would know how can configure Varnish to send access to correct IP, I am going explain: NGINX: Listen in: 10.10.10.10, 20.20.20.20 and 30.30.30.30 on ports: 80 and 443 Proxy redirect to Varnish 10.10.10.10:8080, 20.20.20.20:8080 and 30.30.30.30:8080 Varnish: Port: 8080 - THIS IS THE PROBLEM Proxy content not static to Apache on port 8000 - THIS IS THE OTHER PROBLEM Apache2: Listen in: 10.10.10.10:8000, 20.20.20.20:8000 and 30.30.30.30:8000 Response correct VirtualHost This is the idea. When I try with one IP only, all work correctly, because Varnish is only listen in one IP and port and send to backend in one IP and port too. Could you help me to configure Varnish or there is a best way to configure similar scenario please?

  • Trixbox: external SIP with no sound

    - by Leandro Vidal
    I have a trixbox server and every works find except the external SIPs. Inside net all sound goes fine, but if I use a SIP phone outside the net, I can connect, I can receive calls but I there is no sound. I have this text in the sip_nat.conf: nat=yes externhost=xxxxx.dyndns.org localnet=192.168.1.0/255.255.255.0 localhost=192.168.1.210 externrefresh=10 qualify=yes And I have the ports from 5036 to 5082, 4569 and from 10000 to 20000 redirected to 192.168.1.210 on TCP and UDP. What's wrong? Thank you very much in advance

  • NVIDIA same chipset, but different implementations - what is the difference?

    - by Horst Walter
    I have planned to buy a graphics card. When searching for a particular chipset (e.g. GTX 460) I find cards of different vendors (i.e. Gigabyte, Palit, PNY, ...). I can figure out differences in frequency, memory, and equipment. When I read test reports, usually a particular NVIDIA card is compared with its ATI/AMD "counterpart" - have not really found a comparison of all vendors for a particular NVIDIA chipset. So in order to make a decision: a) Are the drivers all the same for all the cards of a particular chipset (and provided by NVIDIA or the vendor?) b) How to figure out which card actually to buy. OK, I choose chipset, and memory, and check the card has the required ports, but then ....

  • Firewall software that can block access to certain applications on certain internet connections

    - by webmasters
    I have two internet connections, a LAN and a 3G modem on a Windows 7 machine. The LAN is connected to a Edimax router which is conneted to the ISP (with their own modem). Now, the Edimax router is set to auto assign IP adresses in the range: 168.192.2.100 and 192.168.2.200 I wanted to block internet explorer to access the LAN. I entered my AVG firewall, selected iexplorer and added a "block" rule which blocked all ports, TCP and UDP protocols for the above IP range. The problem is it did not work, not matter what rules I have tried. Can you recommend a firewall that can easily accomplish this? Ty

  • Using using a DVI instead of a VGA increase computer screen monitor resolution

    - by Jessica M.
    This is for a computer screen. Both my video card and computer screen have DVI ports on them but I'm using a VGA. I'm wondering if there would be a difference if i switch from VGA to DVI. My current resolution is 1920x1080 with the VGA cord. will my resolution increase if i switch to a DVI? Are there any advantage of switching from VGA to DVI? If there will be a difference if i switch, I've read there are 5 different type of DVI cables. how do I know which one to buy?

    - by jack8138
    Hi, I have ESX 4.0 running on NEC Express 5800 R-120a model. I have 2 VMs running windows XP. I am not able to mount any media to it. When I try connecting the local media to the VM, the error message comes mentioning "a connection to the host could not be established.: I have checked and there is no network issue. ESX is accessible fine. Any help would be greatly appreciated. Besides, I have opened almost all the ports in the firewall just to make sure there is no port conflict.

  • vncserver too many security failures

    - by cf16
    I try to connect to my vncserver running on CentOs from home computer, behind firewall. I have installed Win7 and Ubuntu both on this machine. I have an error: VNC conenction failed: vncserver too many security failures even when loging with right credentials (I reset passwd on CentOs). Is it something regarding that I try as root? I think important is also that I have to login to remote Centos through port 6050 - none else port works for me. Do I have to do something with other ports? I see that vncserver is listening on 5901, 5902 if another added - and I consider connection is established because from time to time (long time) the passwd prompt appears,... right? please help, what to do? even if prompt appeared and I put correct password I get: authentication failure. how to disable this lockout for a testing purposes?

  • Sync iPhone Mail with Webmail

    - by João Paulin
    I had an email account [email protected] hosted on Host A. This mailbox had 100 messages. I wanted to migrate to Host B, so I download all the 100 messages from Host A on my iPhone. Now that my site was successfully migrated to Host B and the email account [email protected] was created again (the mailbox is empty), how can I send the messages that I have downloaded on my iPhone to the mailbox on Host B? Note that the migration from Host A to Host B did not change the IMAP and SMTP adressess and parameters. I'm still using the same addresses, parameters and ports as before. The email accounts just switched hosting.

  • Cheapest server per gigabit throughput [closed]

    - by nethgirb
    I'm looking for a set of servers for performance testing a network, and secondarily testing some applications on the servers. Their most important task is simply to pump out data: from an application like memcached or just dumped from a large file in memory into a TCP flow (i.e., disk performance doesn't matter). This should happen over one or more 1 gigabit Ethernet ports, and the machines should run Linux (ideally), or perhaps Mac OS X or some other *nix. Other than that, there are few constraints (e.g., even something ARM-based could be fine). So here's the question: What's the cheapest server per gigabit? Price and power are both considerations.

  • Failures when copying between two external drives on the same controller

    - by Krzysztof Kosinski
    I'm encountering a weird problem which is present both on Ubuntu 9.10 and 10.04, on two different machines. When trying to copy between two external drives connected to the same USB controller, the transfer will randomly hang at some random time (after copying 300MB, 1GB, 10GB - it doesn't appear to depend on the dataset being copied). The hang appears to happen faster in 10.04. It appears to happen slower if both drives are connected to a hub. If the drives are connected to 2 distinct physical ports on the machine, the hang will be very fast. Hangs cannot be reproduced if: Data is copied from the first external drive to an internal drive, then to the second external drive Drives are connected to different USB controllers, for example the first one is connected to the built-in controller and the second one via an external PCMCIA controller. lspci says the first machine has an Intel ICH9 USB controller, the second an Intel ICH4. Is this a hardware problem, a kernel problem or a software issue? I used Nautilus when copying the files.

  • SVN Checkout URL - fresh install

    - by Webnet
    I just setup SVN on a server that is running Ubuntu server as a fresh install. I've got it up and running but am having difficult determining how to connect to it. I'm trying to do an import using the local IP address: http://IP/RepositoryName but it's saying it can't resolve the IP. I'm wondering if there's something on the server I need to setup. I have not modified dav_svn.conf because there is another server here that is running SVN (I'm migrating it to a new server) and it's dav_svn.conf is not modified. The current working SVN has a subdomain associated with the IP location of the server but doesn't do anything special with the ports as far as I can tell. I'm getting this error via RapidSVN when I try to import... Error: Error while performing action: OPTIONS of 'http://IP/RepositoryName': could not connect to server (http://IP) Any help would be appreciated

  • Installing TKInter for Python 2.6.5

    - by Azfar
    Well today's been a bit of shock. After running port -v selfupdate followed by an attempt to run sudo port install py26-ipython MacPorts went around installing a whole host of stuff, including updating my Python from 2.6.4 to 2.6.5. It's nice but unexpected in a creepy way. So I tried to install TKInter using MacPorts with port search tkinter yielding: py-tkinter @2.4.6 (python, graphics) Python bindings to the Tk widget set py25-tkinter @2.5.4 (python, graphics) This is a stub. tkinter is now built with python25 Found 2 ports. So I tried sudo port install py25-tkinter and then it tries to install Python 2.5.5. There must be an easier way to install TkInter without being faffed around... help please?

  • In Varnish stats, what does "Backend conn. reuses" and "recycles" mean?

    - by electblake
    I have varnish installed and I think it's working properly (not sure if it matters but I am using iptables reroute method to route ports incoming:80 > varnish:8080 > apache:80 Anyway, In varnishstat I see a pretty high Hitrate average (60-80%) which I am working on but I am unclear at what all of the stats presented by varnishstat Specifically the following Backend stats: 380 0.00 0.26 Backend conn. success 10122 15.00 6.85 Backend conn. reuses 267 0.00 0.18 Backend conn. was closed 10391 15.00 7.04 Backend conn. recycles I've read a blog post called "Varnishstat for dummies" which outlines a lot of details of varnishstat (I recommend it for beginners) but it does not go over these Backend stats. Feel free to explain here or link to a resource I've missed :) thanks!

  • Connected 2 routers, but they won't talk

    - by ekolis
    I'm trying to set up a second WLAN at home (since the Nintendo DS firmware won't connect to my WPA-encrypted main WLAN), but when I connect my second router's WAN port to one of my main router's LAN ports, the routers won't talk, and I can't connect wirelessly to the second router. I can still see the second router's WLAN - I am just unable to connect to it. And it seems that even the main router can't see the second router, despite being plugged directly into it - I went to the main router's admin console and pinged the second router (which is receiving an IP address), but it was unable to reach it! Does anyone know what might be wrong? Thanks!

  • Can iptables allow Squid to process a request, then redirect the response packets to another port?

    - by Dan H
    I'm trying to test a fancy traffic analyzer app, which I have running on port 8890. My current plan is to let any HTTP request come into Squid, on port 3128, and let it process the request, and then just before it sends the response back, use iptables to redirect the response packets (leaving port 3128) to port 8890. I've researched this all night, and tried many iptables commands, but I'm missing something and my hair is falling out. I thought something like this would work: iptables -t nat -A OUTPUT -p tcp --sport 3128 -j REDIRECT --to-ports 8990 This rule gets created ok, but it never redirects anything. Is this even possible? If so, what iptables incantation could do it? If not, any idea what might work on a single host, given multiple remote browser clients?

  • Can't connect to sql server 2008 named instance

    - by hcsrpm
    I have sql server 2005 and 2008 running on a server on my local (and very straightforward) network. Using sql management studio 2008 and visual studio 2008, I can connect over the network to the 2005 instance which is the default instance. I can't connect to the 08 instance (named MC08). I can connect to both when logged in to the server. Remote connections have been enabled for MC08 and dynamic ports is turned off (assigned to port 1045). The sql browser service is running as well. This used to work so I'm not sure what has changed. I can't connect using the IP address either. Nothing unusual in the event log either. Any ideas?

  • Not able to connect to perforce server outside of localhost

    - by bobber205
    My setup is a Qwest PK5000 router with a Linksys router running Tomato. I have DMZ pointed towards my router. (The server is on the tomato router). I tried my applications that open up sockets and Utorrent (port 6883) and I ended having to do advanced port forwarding and forward specific ports in addition to having DMZ on my router. The problem is that I cannot connect to perforce when on another machine on the LAN or off. Any ideas? :) Thanks!

  • Can i have a Asterisk IP PBX Server Behind ISA 2000

    - by garyb32234234
    Hello Is it a simple procedure to configure ISA Server 2000 to allow an Asterisk IPPBX connect to SIP provider. On asterisk forums they say the ISA has difficulties handling SIP, softphones that i have installed behind the firewall work fine with the provider when the firewall client is installed on the workstation. With asterisk being a linux based system this will not be an option. Is the config a matter setting up port forwarding, is this a more complicated task on ISA server than just selecting the ports i need and then the ip of the internal machine i want to forward them to? UPDATE: I dont think this is possible from what ive researched Regards Gary

  • Connect wired-only devices to a remote wireless access point?

    - by billpg
    Hi everyone. In building A, I have a Netgear wireless access point using WPA2. Works great, no problems. In building B, I have some devices that only have wired Ethernet ports. They can't see my access point. What I need is a gizmo that connects over-the-air to my access point in building A, talks WPA2, and converts the packets to and from a wired Ethernet port. Netgear-access-point in building A      (WPA2 WiFi) Wireless bridge device          <-- Looking for this.      (Cat5 ethernet) My devices in building B. I've looked for devices on Amazon, but the descriptions are infuriatingly unclear. It says it supports WPA2, but does it support it as a client? Grrr... Any recommendations please?

  • Booting from e-sata drive

    - by petersohn
    I have a HP EliteBook laptop (don't know exact product number), which has an internal hard drive with Windows installed on it. I have an external hard drive with e-sata and USB ports, linux installed on it. When I try to boot from the external drive, it works if I use USB but not if I use e-sata. In the BIOS setup, I have the following boot order set: External SATA drive USB Hard Drive Notebook Upgrade Bay Notebook Hard Drive etc. When I boot from another drive (such as the internal hard drive or from CD-ROM), and have the e-sata cable connected, it works perfectly. Is there any way to boot from the e-sata drive?

  • How to "restart/repair" an USB port?

    - by Click Ok
    My laptop has two USB ports, but one is broken, so I use a USB hub in the other good USB port. In that USB hub, I use a mouse and keyboard. Suddenly, that USB port doesn't detect the mouse and the keyboard (even with the light of the hub is on), and the only solution that I found is restarting the laptop. But just some minutes and the keyboard and mouse goes undetected again... Is there some method, software, etc. to "restart/repair" the USB port without restarting the PC?

  • Radeon 5850 Why am I not getting 3 monitors up as a choice ??

    - by Jan
    Ive just bought the top end ATI Radeon card with 2 normal monitor ports and a HDMI. The idea was to continue using my dual screen setup as always and to use the last plug, the HDMI on my TV. I got a new 52 inch HD TV with all the necessary bits. This should work fine. But.. in Display Properties I still get only my 2 monitors up as options. Not the Digital TV. When I unplug 1 monitor and restart the computer, I get the TV and the other monitor. But never all 3 at the same time. Why is this ? Where can I go to tell it that I need all 3 screens at the same time. Also I get a message saying my gfx card also gives sound through the HDMI cable.. But the TV tells me its recieving a sound format that it does not understand. Any ideas on that too while were at it ?

  • SMTP port open - but not open

    - by Frederik Nielsen
    As some of you might know, I am setting up an exchange server. Now I ran into another problem: I cannot connect to the SMTP service from outside the server! The ports are opened in the gateway device (a ZyXEL USG50), Windows firewall is off. I see the packets travekl through the ZyXEL firewall, and I can also see the packets with wireshark on the server, so I know they are getting all the way in to the server. I also know it receives them, and sends out the reply - and this is where things go bad! Analyzing with wireshark, I get these errors in the return packets: Header checksum: 0x0000 [incorrect, should be 0x0779 (may be caused by "IP checksum offload"?)] And: Acknowledgment Number: 0x8e3337d1 [should be 0x00000000 because ACK flag is not set] What the (sorry my French) hell is going on? I really cant figure it out.. Thanks in advance.
