• pfsense CARP - wan failure on firewall

  - by eldblz

  I have recently configured 2 firewall (on 2 DELL PowerEdge R210II with ESXI 5.1) with pfsense. We have several LANs and 2 WANs. Everything is running fine but i have a strange behavior: i can access internet from alla LANs but not from the firewall (itself). For example the firewall cannot retrive package information or if i setup a gatway monitor ip (like google 8.8.8.8 ) this fails. These are the screenshots of firewall configuration: http://imgur.com/a/LNuMz#0 ATM i kept firewall rules to minimum to avoid problem or conflicts. Any ideas how to solve the problem? Thank you in advance.

• First requests are painfully slow

  - by winSharp93

  I am running Redmine under IIS using Zoo. Installation was done using the Web Platform Installer and the default configuration has not been touched. However, when using the application, the first requests take very long to complete (sometimes more than one minute). During that time, the ruby.exe causes some CPU load (about 15%). According to the log files, it's mainly the views taking that long to render: Started GET "/redmine/login" for IP at 2012-09-04 09:54:08 +0200 Processing by AccountController#login as HTML Rendered account/login.html.erb within layouts/base (42150.5ms) Completed 200 OK in 43508ms (Views: 43008.5ms | ActiveRecord: 0.0ms) Rendered account/login.html.erb within layouts/base (42435.1ms) Completed 200 OK in 44100ms (Views: 43523.3ms | ActiveRecord: 0.0ms) After the initial delay, further request times are totally acceptable. Any ideas on how to speed up the warmup time?

• Suggestions for a SOHO/Home Asterisk system

  - by James

  I would like to buy a small embedded system that runs Linux and Asterisk. I would like two FXS ports ( to plug analogue phones into ) and one FXO port ( to plug in to my real line to allow access to the POTS ). I would like it to have a USB port to hold storage for voicemail. I really want it for home use so I would like it to be under £150 ( say $250 ), given that you can buy ADSL routers for around this much can any of them be made to run Linux and Asterisk? I don't want a PC as the power usage would be too high. I am looking for something like this ASDL router but open and able to run Asterisk or another open PBX. At worst I would like a box which had one FXO and two FXS and just made them completely available over IP to a full Asterisk system on a low power Atom system.

• Ubuntu VPN Server (PPTPD) Configuration - Pass Traffic to Internet

  - by SnAzBaZ

  I am trying to configure PPTPD on my Ubuntu box to pass all VPN traffic through to it's internet connection, so I essentially want it to work like a Proxy. I think the problem is that no default gateway is being assigned to my PPTP client (Windows 7). I can connect to the VPN fine, I get an IP address and DNS servers but no default gateway. Do I need to configure a specific option to tell the VPN server to forward all traffic it receives down it's eth0 port and out to the internet. Thanks!

• Measuring cumulative network statistics per user or per process

  - by zsimpson

  I've been googling for hours -- Under Linux I want to know the cumulative bytes sent and received by user or by process over all ip protocols. The best I've found in my searches is that it's possible to use iptables to mark packets for a user, for example: iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner test -j MARK --set-mark 1 It appears that "tc" can then shape traffic with that but I just want the statistic -- I don't want to shape the traffic. I want something like: "user U has transmitted used XMB since time Y". I can't figure out how to get statistics from these marked packets. Also, I've looked at nethogs but they seem to be measuring the instantaneous flow and I need cumulative counts. Anyone have ideas?

• Routing and Remote access rule not being applied internally (Windows SBS)

  - by Tim Saunders

  Hi, I have a Microsoft Small Business Server. I have pointed an external domain name to the external fixed IP address for the server. In routing and remote access I have defined a service for our subversion server as follows: Incoming port: 8443 Private address: 192.168.10.5 Outgoing port: 8443 192.168.10.5 is our development server, not the SBS (which is at 192.168.10.1) This rule works correctly if I am not on our internal network. However if I am on the internal network this rule does not get applied. What can I do/set so this rule is applied both internally and externally (so users with laptops et, don't keep having to change the URL by which they access the subversion server) Not sure what other info you may need, so please let me know if more details are required.

• Samsung i780 networking problem

  - by Infinity

  Hello guys! Maybe this is not the right place to ask this, but I give a try for it. Please don't rate it down, just ignore it if you don't like. So I have a Samsung i780 mobile phone and I would like to use the internet through my wireless router. I have connected to it. I got an IP address. My laptop is also connected to the same wireless network and I can ping the mobile phone and I get answer. When I open the internet explorer and enter an address it says that it cannot connect to the internet. I have googled very much, but can't find the problem. What do you think, what is the solution?

• Drupal + Lighttpd: enabling clean urls (rewriting)

  - by Patrick

  I'm emulating Ubuntu on my mac, and I use it as a server. I've installed lighttpd + Drupal and the following configuration section requires a domain name in order to make clean urls to work. Since I'm using a local server I don't have a domain name and I was wondering how to make it work given the fact the ip of the local machine is usually changing. thanks $HTTP["host"] =~ "(^|\.)mywebsite\.com" { server.document-root = "/var/www/sites/mywebsite" server.errorlog = "/var/log/lighttpd/mywebsite/error.log" server.name = "mywebsite.com" accesslog.filename = "/var/log/lighttpd/mywebsite/access.log" include_shell "./drupal-lua-conf.sh mywebsite.com" url.access-deny += ( "~", ".inc", ".engine", ".install", ".info", ".module", ".sh", "sql", ".theme", ".tpl.php", ".xtmpl", "Entries", "Repository", "Root" ) # "Fix" for Drupal SA-2006-006, requires lighttpd 1.4.13 or above # Only serve .php files of the drupal base directory $HTTP["url"] =~ "^/.*/.*\.php$" { fastcgi.server = () url.access-deny = ("") } magnet.attract-physical-path-to = ("/etc/lighttpd/drupal-lua-scripts/p-.lua") }

• Nodejs for processing js and Nginx for handling everything else

  - by Kevin Parker

  I am having a nodejs running on port 8000 and nginx on port 80 on same server. I want Nginx to handle all the requests(image,css,etc) and forward js requests to nodejs server on port 8000.

• How to make AD highly available for applications that use it as an LDAP service

  - by Beaming Mel-Bin

  Our situation We currently have many web applications that use LDAP for authentication. For this, we point the web application to one of our AD domain controllers using the LDAPS port (636). When we have to update the Domain Controller, this has caused us issues because one more web application could depend on any DC. What we want We would like to point our web applications to a cluster "virtual" IP. This cluster will consist of at least two servers (so that each cluster server could be rotated out and updated). The cluster servers would then proxy LDAPS connections to the DCs and be able to figure out which one is available. Questions For anyone that has had experience with this: What software did you use for the cluster? Any caveats? Or perhaps a completely different architecture to accomplish something similar?

• Why can't connect with second computer in same LAN and settings?

  - by user930450

  I'm trying to connect to WLAN with notebook. The notebook works fine with other WLANs. It can authenticate, signal is "very good" but it says "can't access internet". (On Windows it's small yellow exclamation mark on the signal). With other computer exactly in the same location, with the same settings, it's possible to connect. Both are configurated to get IP dynamically. One difference is that the other computer is using "Ralink wireless" instead normal windows client to connect. But does this make a difference? the settings are the same. What could be the reason?

• Help with Apache rewriteengine rules

  - by Vinay

  Hello - I am trying to write a simple rewrite rule using the rewriteengine in apache. I want to redirect all traffic destined to a website unless the traffic originates from a specific IP address and the URI contains two specific strings. RewriteEngine On RewriteLog /var/log/apache2/rewrite_kudithipudi.log RewriteLogLevel 1 RewriteCond %{REMOTE_ADDR} ^199\.27\.130\.105 RewriteCond %{REQUEST_URI} !/StringOne [NC, OR] RewriteCond %{REQUEST_URI} !/StringTwo [NC] RewriteRule ^/(.*) http://www.google.com [R=302,L] I put these statements in my virtual host configuration. But the rewriteengine seems to be redirect all requests, whether they match the condition or not. Am I missing something? Thank you. Vinay.

• Virtualbox Ubuntu 10.04 on Windows 7: networking won't work

  - by Herbert Roitblat

  I have a virtualbox image that I created using libvirt from Ubuntu 10.04. It assigns a fixed IP address. I can start it up on my Windows 7 VirtualBox, but I cannot get networking to work. My colleague loaded the same image onto his Windows 7 and networking worked as a bridged connection. Therefore, I know that the image is good, it must be something about my Windows 7 installation. Any thoughts on where to look to get networking running in my virtual machine? Thanks, Herb

• Can admins monitor my activity locally even when I use a VPN?

  - by Arjun Create

  My school has one of those super overreacting web blockers (specifically Fortisnet) that blocks things that should be accessible by a high-school senior trying to research projects. Despite many students' complaints the administration's hands are tied due to parents' complaints. I have setup a VPN account from http://www.vpnreactor.com. With this I am able to bypass the blocker. I know this service hides my IP from websites and servers on the web. I also know that the school pays an IT guy just to monitor sites and network traffic that the students are using. Basically, will he be able to see my network traffic? More importantly, will he be able to trace it to my computer or its MAC address? I am connecting over Wi-Fi, not ethernet.

• LinkSys WRT54GL + AM200 in half-bridge mode - Setup guide recommendations?

  - by Peter Mounce

  I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. My ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• Hosting online with xampp?

  - by Andrew

  I'm not quite sure what I'm doing wrong, because from what I've read, this should all be working. What I've done: Forwarded ports 80, 8080, and 443. Changed the ServerName localhost:80 line in \apache\conf\httpd.conf to ServerName myip:80. Registered at dyndns.com, and have been using their update client to link my IP to the DNS thingy. Made sure xampp was using port 80, and started apache and MySql. And...nothing. What did I miss? =/.

• How Do I Change the Windows7 LAN Proxy Config from the Command Line

  - by david.barkhuizen

  In Windows7, Is it possible to define/change the proxy config from the command line ? So, using the gui, I would go: Start Control Panel Network and Internet Internet Options Connections LAN Settings and then - enable/disable the proxy - define IP:port of proxy server But I would like to rather do this from the command line (so that I can run the command from a batch-file with a shortcut key - enabling me to switch proxy configs using a short-cut, rather than having to wade through the MS wizard). I've looked at using netsh.exe to change the settings for WinHTTP, but this seems to be thr wrong thing to do, as the WinHTTP setting do not appear to be related to the LAN settings. Much appreciated folks.

• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• Routing traffic to specific web sites through Ethernet, rest via wifi on Mac OS X 10.6?

  - by user32448

  Hi I have two separate Internet connections connected to a Mac and I'd like one of them (via Ethernet eth0 gateway 192.168.2.1) to serve for just backing up to an remote online storage, and the other one (via Airport en1 gateway 192.168.1.1) for all other Internet traffic. I tried using "route" from the terminal as follows: sudo route add -host 98.207.226.113 -interface eth0 (just for testing against the site www.whatismyip.org whose IP is 98.207.226.113, to see through which gateway the traffic is routed) I can see using netstat that the route is added: $ netstat -rn -f inet Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 192.168.1.1 UGSc 49 0 en1 98.207.226.113 192.168.2.1 UGSc 0 0 eth0 However, the traffic in this case does NOT get routed properly through Ethernet, as if the routing definition I made is ignored. Any ideas? Thanks!

• Exchange enrypted messages with a single recipient [portable]

  - by Andy

  I need to exchange encrypted messages with another party. These would be in the form of email like communication (not instant chat). The solution needs to be portable (USB stick). I've tried "Portable Thunderbird/Enigmail/Gnupg/Hotmail account" but it's just impossible to setup portable, countless meaningless error messages. Anyway, I would prefer something more straightforward. Notes: We won't know each others IP addresses. Our computers will often be switched off. Encryption would ideally be using a common password. Is there a solution to this?

• Configuring port forwarding on Fortigate 50B

  - by GomoX

  I can't for the life of me get port forwarding to work on my Fortigate 50B. I followed the setup tips described on this other SF thread with no success. The only specific difference I can find is we are using load balancing through 2 different internet uplinks. Is there any caveat specific to this scenario that I might be missing? If you need any specific additional information please ask because I think I have checked everything: Virtual IP mapping on external interface wan1 ACCEPT all from any on wan1 to the corresponding server on internal No seeming offending firewall rules (any specific pitfalls that I might want to check for?)

• Declaring multiple ports for the same VirtualHosts

  - by user65567

  Declare multiple ports for the same VirtualHosts: SSLStrictSNIVHostCheck off # Apache setup which will listen for and accept SSL connections on port 443. Listen 443 # Listen for virtual host requests on all IP addresses NameVirtualHost *:443 <VirtualHost *:443> ServerName domain.localhost DocumentRoot "/Users/<my_user_name>/Sites/domain/public" <Directory "/Users/<my_user_name>/Sites/domain/public"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on ... </VirtualHost> How can I declare a new port ('listen', ServerName, ...) for 'domain.localhost'? If I add the following code, apache works (too much) also for all other subdomain of 'domain.localhost' (subdomain1.domain.localhost, subdomain2.domain.localhost, ...): <VirtualHost *:80> ServerName pjtmain.localhost:80 DocumentRoot "/Users/Toto85/Sites/pjtmain/public" RackEnv development <Directory "/Users/Toto85/Sites/pjtmain/public"> Order allow,deny Allow from all </Directory> </VirtualHost>

• Server 2012 R2 DNS Conditional forwarding not working reliably, possible caching issue?

  - by Matt

  I have a bit of a home lab setup with a domain controller that is acting as the DNS server for my network. For everything, it's working fine and forwards external DNS requests to my ISP. The household recently wanted to get Netflix going and it seemed a DNS option was better than a VPN to get around the region locking, so I signed up for unblock-us.com Since I have a Windows DNS server I thought I'd be clever and make use of conditional forwarders and added the Netflix domain to the list. Initially this worked well and all devices on the network could now access Netflix, however after about an hour going to the Netflix site would result in a page cannot be found. Doing an nslookup of Netflix.com from my PC resulted in it not returning any IP addresses. As a test, I deleted the Netflix domain from the DNS servers cache and things started working again - devices could get to the site again however the same thing happens again after around half an hour to an hour. Have I missed something here that's causing it to stop working?
