  • “X_FORWARDED_FOR” Header Doesn't Present In The Request

    - by Radi
    In my web application I need to extract the real ip address for clients behind proxy, after searching I found that the possible method to do that is to read the content of "X_FORWARDED_FOR" header , I am using java servlet and the headers of the incoming request doesn't contain "X_FORWARDED_FOR" header , So why the header doesn't included in the request? I am using java 1.7 , tomcat v7 , proxy server :TMG and configured to use "X_FORWARDED_FOR" header . Please advice. Thanks in advance.

  • Sending single emails works, but sending to the same email in a distribution list is bounced

    - by EvilChookie
    I'm running an Exchange 2003 server on a Telstra Business internet connection (in Australia). I'm routing emails through the SMTP connecter, using the host smtp.telstrabusiness.com When users send single emails to a single recipient, the emails are sent correctly. However, when users send emails to a distribution list, they bounce back with: The message could not be delivered because the recipient's destination email system is unknown or invalid. Please check the address and try again, or contact your system administrator to verify connectivity to the email system of the recipient. One of the people in the list was able to recieve a single email from us just a few minutes afterwards, but did not recieve any of the email that should have come from the distribution list. Is there a way I can throttle the number of messages that Exchange will send at a time, so as not to appear as spam to Telstra?

  • How do I check a reverse PTR record?

    - by Daisetsu
    I need to check a reverse PTR record to make sure that a script I have is sending emails which will actually received by my users and not incorrectly marked as spam. I understand that the ISP which owns the IP range has to set up the PTR record, but how do I check if it is already set up?

  • Setting up Virtual Hosts with Apache on Windows 2008 server for multiple sites. Complicated setup,

    - by Roeland
    Hey guys! I am setting up apache on my windows 2008 server at my home. It will serve 2 functions. Subversion hosting to allow me and some others to manage company documents with version control Local website hosting for web development. Will need to run several websites since I generally work on more then one site at a time. Heres what I have done so far. I set up subversion and apache 2.2 using some walk troughs. I changed the default port to 1337. (im a nerd) Using dyndns.com I created a domain to forward to my home ip which is dynamic. ( company.gotdns.org) I then went into my DNS for my company.com and added a record to point repo.company.com to company.gotdns.org At this point people who need access to my file repository can access by going to repo.company.com/repo which is good so far. My question comes on the next step, setting up virtual hosts with apache. Ideally I would like to have my local website be viewable by some others in the company from their homes. So, say I am working on site1, I would like to have them be able to view this by going site1.roeland.bythepixel.com. At the same time, I would like to have site10.wouter.bythepixel.com go to his local setup for site10. What I have done for this: I went into my DNS for company.com and added a record to point roeland.company.com to company.gotdns.org (which translates to my ip). I added code to my httpd-vhosts.conf (listed at bottom) I added code to my host file (listed at bottom) Hah, so of course this doenst work as excepted.. going to site1.roeland.bythepixel.com doesnt bring up my test1 site. Could anyone point me where I may be going wrong? Thanks! hosts: 127.0.0.1 localhost 127.0.0.1 sensenich.roeland.bythepixel.com ::1 localhost httpd-vhosts.conf: <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "F:/Current Projects/sensenich.com" ServerName sensenich.roeland.bythepixel.com ErrorLog "logs/sensenich.roeland.bythepixel.com-error.log" CustomLog "logs/sensenich.roeland.bythepixel.com-access.log" common </VirtualHost>

  • How can I selectively increase latency? E.g. throttle games

    - by Arcymag
    Basically, I want networked games to run poorly on a network, but I want everything else to run smoothly. I would also appreciate advice on blocking games in general. As far as I can tell, there's a few ways to completely prevent an internet game from running: Blocking entirely via DNS configuration (e.g. hosts file), or router DNS configuration Blocking entirely via a separate DNS server Blocking the application, by uninstalling or some kind of access control Blocking the application by automatically killing the process every once in a while Blocking the application by corrupting files periodically However, I would like a more subtle way to block a program. Something that either: Increases latency (would this be doable through some kind of QoS like what DD-WRT offers?) Increases latency by using a special routing configuration for specific target IPs Throttle other systems resources, such as memory, IO, or CPU Screw around with keyboard configurations when a game is launched I would like this to work on MacOSX and Windows, but Linux would be great too. FYI I don't have a kid, but I was brainstorming with some friends and parents.

  • How do I connect to MySQL when it's setting behind 2 layers of ssh?

    - by David Corley
    I have a MySQL server sitting behind a bastion server that I wish to connect to from my local machine. Ideally I want to port-forward the MySQL port (3316 in this case) to a local port on my machine. I've tried plink -ssh -L 3306:my.sql.ip.address:3316 my.bastion.server ,but this is not working. I've got one ssh login for the bastion server and another login for the machine mysql server is running on.

  • Squid Proxy: url_regex acl is not working?

  • Internet connection sharing between Windows XP and Windows 7

    - by Dave
    I bought my lil sister's netbooks for Christmas and I've been having a heck of a time trying to get Internet Connection Sharing to work. The host computer is a Windows XP box and it uses a US Cellular 3G modem dongle thingy to set it's Internet access. Additionally I have a hard wire plugged into the LAN1 port of the router described below. (I tried the WAN port out of desperation but things didn't seem happy that way.) Additionally they have a linksys router (can't remember specific model number, I will find this out) that I was using to take advantage of it's wireless capabilities. Originally thought about updating the router to use dd-wrt, but after reading the instructions it looked like to much of a pita (had to downgrade firmware, then install dd-wrt) to set up, eventually I caved, out of desperation, and ended up successfully installing dd-wrt on the router. I have DHCP turned off on the router, actually all I could select was DHCP forwarder. The netbooks both have windows 7 starter installed on them. Initially, I had the networks joined to a homegroup but I dropped that and everyone is able to see everyone in their respective network explorers. When I turn on Internet Connection Sharing on the host, its IP on the LAN changed to 192.168.0.1, so I arbitrarily decided to assign the router to port 192.168.0.100. When I connect the netbooks they get IPs dynamically. As I stated before, everyone can see everyone in the network explorer, and shares can be accessed. The weird thing is that everyone can ping the router but they cannot ping each others IPs. The status on the netbooks says that there is no Internet Connectivity. Another thing I tried was manually setting the DNS servers on the netbooks to the DNS servers that the host computer has. The funny thing is when I ping an outside domain such as google.com the IP address resolves, however I get no responses from the pings. When I tried plugging the host into the WAN port I could ping the router, nor could I access the router's web access admin. Another thing I tried was turning off the firewall on the netbooks and the firewall off on the host computer for the LAN connection, and they still could not ping each other. Also I thought I should be able to start a remote desktop connection but I couldn't do that either, I also checked to make sure that computers would in fact accept a request for remote desktop connections.

    - by mactruck
    I have 2 websites, site A running on port 80 and site B configured to run on port 8080. I can access site A no problem, but site B I can only access from the local web server machine. Externally it is not accessable, I have tried the url and ip and neither work. I have tried different configuring on port 8081 as a test and that didnt work either. What IIS settings should I look at?

  • nsclient++ intermittent connection refused on same subnet

    - by jshin47
    I have setup Nagios and nsclient++ on a number of my Windows servers. They are all in the same subnet so no routing or firewall stuff is taking place in between the endpoints, and I have verified that the firewalls on the servers are not causing trouble. The problem is that the scheduled checks sometimes fail with "connection refused" and sometimes work! It is a frustrating problem to resolve because I do not know what to look for. One place I did look is in the nsclient++ logs, where I am seeing this recurring error: ...\trunk\modules\CheckSystem\PDHCollector.cpp:148: Failed to query performance counters: \238... This sounds promising, but I couldn't find much on Google about this error as it pertains to NSClient++

  • ECMP Load Balancing in JUNOS

    - by SpacemanSpiff
    I'm trying to figure out how to use ECMP load balancing in JUNOS. I know this isn't the best way to load balance, but its quick and dirty and gets done what I need to. In ScreenOS this was pretty easy. Device: SRX220 JunOS: 10.3R2.11 Here's what I've got so far: routing-options { static { route 0.0.0.0/0 { next-hop [ 1.1.1.1 1.1.1.2 ]; metric 10; } } maximum-paths 2; Will that do it? Tom

  • Router/Security question: Am I hacked?

    - by IVR Avenger
    Hi, all. I've noticed that my home broadband speed seems to be a bit slow in recent days. I noticed, last night, that my Wireless Router had given a DHCP lease to a public IP address with an odd formation; something like 111.10.11.110. Should I consider these warning sings of my ZyXEL router being compromised in some way? Thanks, IVR Avenger

  • Multiple WAN interfaces in same subnet on Sonicwall NSA220?

    - by Ttamsen
    (eta salutation, which keeps getting eaten.) Hi, all. I see a bunch of related questions, so I'm hesitant to ask, but: I have a situation where I have a Sonicwall NSA220 serving as firewall/router for two internal subnets to two external WAN connections. In some locations this is two separate ISPs. In others, it's the same ISP but with multiple circuits. The problem is that one ISP has been unable to provide unique subnets for each WAN interface. Is there any possibility that I might be able to bond the two WAN interfaces into a single virtual interface, and then use source-routing to get internal subnets communicating out the appropriate physical interface? Or even just use traffic-shaping to give each internal network appropriate shared bandwidth? I haven't found anything in the docs, but it seemed like it might be worth asking. Thanks for any help! -Steve.

  • Redundant Connection Issue

    - by Adam
    I'm trying to set up a redundant connection for our web hosting servers. I have a BGP-capable router connecting two lines from two separate ISP's, one fiber (primary), one DSL (failover). I've already confirmed that I can push routes into the DSL ISP's system, so long as they aren't malicious. My question is, what do I need to do on the fiber side to make those IP's routable through the DSL? Is there something I'm missing?

  • can router configuration cause decreasing of download rate?

    - by behrooz
    My download speed got crazy since I changed the router's IP. But nothing got fixed after doing a factory reset. The speed was 1024 kb/s (128 kB/s) but it is 200kb/s (max) right now. I mean it works good if a request is small (i.e. a HTTP request) but it gets slow if a request has a big response. Help me please. (It is three days I'm downloading VS2010.)
