• Per client DNS server assignment using Pfsense

  - by Trix

  I have a network where pfsense is the gateway. There are two sets of clients that I want. One where there will be some restrictions to the network (example, IM being blocked) and one network where there are no restrictions. One easy way I thought about doing this was assigning the different domains different DNS servers. One set could use OpenDNS, the other could use Google's Public DNS. The set with OpenDNS would have the filter options on (using OpenDNS' dashboard, I can check block IM .... so I do not manually need to block login.oscar.aol.com, meebo.com, gmail chat ....etc). So the problem is the DHCP server looks like it will only assign a single set of DNS servers to clients. Is there a way to set a per client assignment? Is there a better way to obtain what I want to obtain. This is just a small home network. I do not need anything fancy, but I do need this functionality in one way or another.

• Reverse Proxies and AJAX

  - by osij2is

  A client of ours is using IBM/Tivoli WebSEAL, a reverse-proxy server for some of their internal users. Our web application (ASP.NET 2.0) and is a fairly straightforward web/database application. Currently, our client users that are going through the WebSEAL proxy are having problems with a .NET 3rd party control. Users who are not going through the proxy have no issues. The 3rd party control is nothing more than an AJAX dynamic tree that on each click requests all the nodes for each leaf. Now our clients claim that once users click on a node in the control, the control itself freezes in such a way that they don't see anything populate. Users see "Loading..." message appear but no new activity there afterwards. They have to leave the page and go back to the original page in order to view the new nodes. I've never worked with a reverse proxy before so I have googled quite a bit on the subject even found an article on SF. IBM/Tivoli has mentioned this issue before but this is about all they mention at all. While the IBM doc is very helpful, all of our AJAX is from the 3rd party control. I've tried troubleshooting using Firebug but by not being behind the reverse proxy, I'm unable to truly replicate the problem. My question is: does anyone have experience with reverse proxies and issues with AJAX sites? How can I go about proving what the exact issue is? Currently we're negotiating remote access so assume for the greater part that I will have access to a machine that's using the WebSEAL proxy. P.S. I realize this question might teeter on the StackOverFlow/ServerFault jurisdictional debate, but I'm trying to investigate from the systems perspective. I have no experience with reverse proxies (and I'm unclear on the benefits) and little with forwarding proxies.

• URL Rewriting on GoDaddy Virtual Server

  - by Aristotle

  I migrated a Kohana2 application from a shared-hosting environment over to a virtual dedicated server. After this migration, I can't seem to get my .htaccess file working again. I apologize up front, but over the years I have never experienced so much frustration with anything else as I do with the dreaded .htaccess file. Presently I have my project installed immediately within a directory in my public folder: /var/html/www/info.php (general information about server) /var/html/www/logo.jpg (some flat file) /var/html/www/somesite.com/[kohana site exists here] So my .htaccess file is within that directory, and has the following contents: # Turn on URL rewriting RewriteEngine On # Installation directory RewriteBase /somesite.com/ # Protect application and system files from being viewed # This is only necessary when these files are inside the webserver document root RewriteRule ^(application|modules|system) - [R=404,L] # Allow any files or directories that exist to be displayed directly RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # Rewrite all other URLs to index.php/URL RewriteRule .* index.php?kohana_uri=$0 [PT,QSA,L] # Alternativly, if the rewrite rule above does not work try this instead: #RewriteRule .* index.php?kohana_uri=$0 [PT,QSA,L] This doesn't work. The initial controller is loaded, since index.php is called up implicitly when nothing else is in the url. But if I try to load up some other non-default controller, the site fails. If I place the index.php back within the url, the call to other controllers works just fine. I'm really at my wits end, and would appreciate some direction here.

• PECL install error after upgrading to OSX 10.8

  - by Clive

  I've just upgraded my OS to Mountain Lion and PECL is no longer working (it's on a test drive so no drama, but I'd like to get it working so I can upgrade the OS on my shiny new SSD as well). I'm using the native PHP installation, no macports/homebrew or anything like that. Running sudo pecl install uploadprogress (for example) produces the following terminal output: downloading uploadprogress-1.0.3.1.tgz ... Starting to download uploadprogress-1.0.3.1.tgz (9,040 bytes) .....done: 9,040 bytes 4 source files, building running: phpize grep: /usr/include/php/main/php.h: No such file or directory grep: /usr/include/php/Zend/zend_modules.h: No such file or directory grep: /usr/include/php/Zend/zend_extensions.h: No such file or directory Configuring for: PHP Api Version: Zend Module Api No: Zend Extension Api No: autom4te: need GNU m4 1.4 or later: /usr/bin/m4 ERROR: `phpize' failed I'm guessing the problem is the 3 grep lines. I've found several threads that suggest this is caused by XCode not being installed...but XCode is installed, and updated to the latest version (4.4). All the relevant symlinks to /Developer/usr/bin/* also exist as they should. m4 is currently at version: m4 (GNU M4) 1.4.13, so even though the output above contains a line pertaining to it, I don't think that can be the problem. I'm sure it's just a simple issue, anyone got any clues?

• Samba Server Make Multiple User Permissions Profiles

  - by Scriptonaut

  I have a Samba file server running, and I was wondering how I could make multiple user accounts that have different permissions. For example, at the moment I have a user, smbusr, but when I ssh to the share, I can read, write, execute, and even navigate out of the samba directory and do stuff on the actual computer. This is bad because I want to be able to give out my IP so friends/family can use the server, but I don't want them to be able to do just anything. I want to lock the user in the samba share directory(and all the sub directories). Eventually I would like several profiles such as (smbusr_R, smbusr_RW, smbguest_R, smbguest_RW). I also have a second question related to this, is SSH the best method to connect from other unix machines? What about VPN? Or simply mounting like this: mount -t ext3 -o user=username //ipaddr/share /mnt/mountpoint Is that mounting command above the same thing as a vpn? This is really confusing me. Thanks for the help guys, let me know if you need to see any files, or need anymore information.

• Unconvert Text File from Binary Format

  - by Hammer Bro.

  I've got a rather large CSV file (~700MB) which I know to consist of lines of 27-character alpha-numeric hashes; no commas or anything fancy. Somehow, during its migration from Windows to Linux (via winSCP and then a few regular SCPs), it has converted into some kind of binary format I am unfamiliar with. If I open the file in vi, everything appears fine, and it says [converted] at the bottom, although I know it's not a line endings issue (and dos2unix doesn't help). If I 'head' the file, it looks proper except for a "ÿþ" at the beginning of the first line. If I open up the file in nano, however, I see the "ÿþ" at the start and then "^@" before every character (even newlines and EoF). If I try to re-save or copy the file (say via: head file.csv short.txt), this special encoding is preserved. I copied the first ten lines out of vi (which displays it properly) into my Windows clipboard via my SSH client, then pasted it into a new text file, test.txt. This file is visually identical when opened in vi (and similar through 'head', minus the "ÿþ"), although it's roughly half of the filesize. Additionally, file test.txt test.txt: ASCII text file short.txt short.txt: I have no idea what format this once-text file got converted to (it's notoriously hard to search the internet for symbols), but surely there must be some way to convert it back. Any ideas?

• Could not continue scan with NOLOCK due to data movement during installation

  - by dbdev1

  Hi, I am running Windows Server 2008 Standard Edition R2 x64 and I installed SQL Server 2008 Developer Edition. All of the preliminary checks run fine (Apart from a warning about Windows Firewall and opening ports which is unrelated to this and shouldn't be an issue - I can open those ports). Half way through the actual installation, I get a popup with this error: Could not continue scan with NOLOCK due to data movement. The installation still runs to completion when I press ok. However, at the end, it states that the following services "failed": database engine services sql server replication full-text search reporting services How do I know if this actually means that anything from my installation (which is on a clean Windows Server setup - nothing else on there, no previous SQL Servers, no upgrades, etc) is missing? I know from my programming experience that locks are for concurrency control and the Microsoft help on this issue points to changing my query's lock/transactions in a certain way to fix the issue. But I am not touching any queries? Also, now that I have installed the app, when I login, I keep getting this message: TITLE: Connect to Server Cannot connect to MSSQLSERVER. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 67) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=67&LinkId=20476 BUTTONS: OK I went into the Configuration Manager and enabled named pipes and restarted the service (this is something I have done before as this message is common and not serious). I have disabled Windows Firewall temporarily. I have checked the instance name against the error logs. Please advise on both of these errors. I think these two errors are related. Thanks

• Troubleshooting transient Windows I/O "The parameter is incorrect." errors

  - by Kevin

  We have a set of .Net 2.0 applications running on Windows 2003 servers which have started experiencing transient "The parameter is incorrect." Windows I/O errors. These errors always happen accessing a file share on a SAN. The fact that this error has happened with multiple applications and multiple servers leads me to believe that this is an infrastructure issue of some sort. The applications all run under the same domain account. When the errors occur they generally will resolve themselves within a few minutes. I can log in to the application server once the error starts occurring and access the file share myself with no problems. I have looked at the Windows event logs and haven't found anything useful. Due to the generic nature of "The parameter is incorrect.", I am looking for additional troubleshooting suggestions for this error. A sample stack trace is below. Note that while this example was during a directory creation operation, when the problem is occurring, this exception is thrown for any file system operations on the share. Exception 1: System.IO.IOException Message: The parameter is incorrect. Method: Void WinIOError(Int32, System.String) Source: mscorlib Stack Trace: at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.Directory.InternalCreateDirectory(String fullPath, String path, DirectorySecurity dirSecurity) at System.IO.Directory.CreateDirectory(String path, DirectorySecurity directorySecurity) at System.IO.Directory.CreateDirectory(String path)

• help Add Any Application Shortcut in Desktop Context Menu

  - by blackjack

  i got the info here but after adding that i didn't get any shortcut on my desktop contest menu :( pls help me i want it only on my desktop context menu Open regedit and goto: CODEHKEY_CLASSES_ROOT\Directory\Background\shell now under this key create another key with any name and in right-side pane set its value to the label, which you want to show in desktop context menu, like Media Player, Winamp, Firefox, anything else. Now create another key under this newly created key with name command. and in right-side pane set its value to the exact path of application, like: C:\Program Files\Windows Media Player\wmplayer.exe C:\Program Files\Winamp\winamp.exe etc... Thats it. Now you can check your favorite application shortcut in desktop context menu. You can create as many shortcut as you want. Simply create a separate key for all the applications. Following is a ready-made code: CODEWindows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP] @="Windows Media Player" [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP\command] @="C:\Program Files\Windows Media Player\wmplayer.exe" Just change the label and path to ur desired application and save with the name "vishal.reg" (including the quotes) and run it. U can also set the application shortcut to show only when u press key by adding "Extended" String value in right-side pane of the newly created key: CODEWindows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP] @="Windows Media Player" "Extended"="" [HKEY_CLASSES_ROOT\Directory\Background\shell\WMP\command] @="C:\Program Files\Windows Media Player\wmplayer.exe"

• PXE with WDS & Windows Server 2012 - no filename option in DHCP lease?

  - by user1799

  I'm trying to configure Windows Server 2012 (a virtual box VM) with WDS so I can PXE boot some Windows 7 VMs (also virtual box). All the machines involved are only attached to the "host only network", 192.168.56.0/24. The Server 2012 machine has been setup as an AD DS machine, has DNS installed and working along with DHCP with option 60 - PXEClient - set and WDS is set to not listen on DHCP ports. I've followed http://technet.microsoft.com/en-us/library/jj648426.aspx very closely. I've used the boot.wim and install.wim files from the Win 7 installation DVD and they're configured as 'boot' and 'installation' images respectively. When I boot the target machine, it gets an IP address, but I simply get 'no filename' and the boot won't proceed any further. I've tried setting option 66 to 192.168.56.2 (the WDS server) and option 67 to both Boot\x64\wdsnbp.com and Boot\x64\pxeboot.n12 but all to no avail. I can't seem to see anything in the event log, either. Can anyone out there spot what I'm doing wrong? Or give tips to narrow down a diagnostic?

• Cisco ASA intermittently fails to see traffic

  - by DrStalker

  users | Mikrotik -- Internet | ASA | ServerA and ServerB I'm trying to troubleshoot a problem with a new Cisco ASA 5505. The network design is as above - the Microtik is the existing router, ServerA and ServerB used to plug directly into it. ServerA has IP 10.30.1.10, ServerB has IP 10.30.1.11 The ASA is configured with no NAT, a "allow anything" firewall, and uses the microtik as its default gateway. In effect, it is currently a simple IP router; the firewall and VPN stuff will all come later once the basics are working. Th problem is access to ServerA and ServerB is erratic - sometimes it will work, sometimes it will fail. It can fail for either one of the servers only, or both. When it is working: The Mikrotik logs show ping packets being sent out over the proper interface The ASA logs show the incoming connections. When it is failing: The Mikrotik logs show ping packets being sent out over the proper interface The ASA logs show nothing reaching the ASA. This can fail for one server only (e.g.: the Mikrotik is putting out packets to 10.30.1.10 and 10.30.1.11, but the ASA is only seeing packets arrive destined for 10.30.1.11) It can fail for one source only (e.g.: ClientA on the users network can ping 10.30.1.11, but clientB cannot) The problem can also be seen from the mikrotik router itself; sometimes it can ping ServerA and ServerB, sometimes it can only ping one of them What could be causing this? I can't think of any possible cause that is intermittent and could explain why the problem may occur for one destination server and not others. edit: Link to ASA config

• Windows Audio Issue

  - by Nikki

  This one is driving me nuts. Hoping someone can shed some light. I'm running windows 7 using onboard audio. It's been fine for over 2 years but lately there's a problem every time I play audio. I hear a small soft burst of static and the volume turns itself down from 50% to 23%. Once at 23%, it plays fine. No related events logged in viewer. No reported problems with the device. Different headphones, same problem. I played around with audio settings for hours but the problem persists. EDIT: ok more info: Motherboard: ECS G31T-M LGA775 System info displays this: Name High Definition Audio Device Manufacturer Microsoft Status OK PNP Device ID HDAUDIO\FUNC_01&VEN_1106&DEV_E721&SUBSYS_10192683&REV_1001\4&3D4E739&0&0001 Driver c:\windows\system32\drivers\hdaudio.sys (6.1.7600.16385, 297.00 KB (304,128 bytes), 14/07/2009 9:51 AM) I'll keep adding info as I find it. The question I want resolved is; Is it faulty hardware? If so, I can buy a sound card. I can't imagine software is responsible since I haven't installed anything new for weeks. Virus scans are clear as well. The static burst is irritating to say the least. Tried 2 different headphones and separate speakers. Same problem. I know it's not an easy problem but I was hoping someone had encountered the same thing.

• sendmail.exe: Error during delivery. Service not available, closing transmission channel

  - by user2810332

  I have a module in my system that will trigger an email and send it to user. The email will be sent to user when the product in my system is going to expired soon. I test the whole module in localhost and there is no problem with it. Then, I finally moved the module in my server but it gives this error. sendmail: Error during delivery: Service not available, closing transmission channel.

• Subversion gives Error 500 until authenticating with a web browser

  - by Farseeker

  We used to use Collabnet SVN/Apache combo on a Windows server with LDAP authentication, and whilst the performance wasn't brilliant it used to work perfectly. After switching to a fresh Ubuntu 10 install, and setting up an Apache/SVN/LDAP configuration, we have HTTPS access to our repositories, using Active Directory authentication via LDAP. We're now having a very peculiar issue. Whenever a new user accesses a repository, our SVN clients (we have a few depending on the tool, but for arguments sake, let's stick to Tortoise SVN) report "Error 500 - Unknown Response". To get around this, we have to log into the repo using a web browser and navigate 'backwards' until it works E.G: SVN Checkout https://svn.example.local/SVN/MyRepo/MyModule/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/MyRepo/MyModule/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/MyRepo/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/ - Forbidden 403 (correct) Webbrowse to https://svn.example.local/SVN/MyRepo/ - OK 200 (correct) SVN Checkout https://svn.example.local/SVN/MyRepo/MyModule/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/MyRepo/MyModule/ - OK 200 (correct) SVN Checkout https://svn.example.local/SVN/MyRepo/MyModule/ - OK 200 (correct) It seems to require authentication up the tree, starting from the svnparentpath up through to the module required. Has anyone seen anything like this before? Any ideas on where to start before I ditch it back to Collabnet's SVN server?

• Dell Poweredge 2600 RAID Transfer How-to

  - by DCookie

  Help, please! Hardware: Dell Poweredge 2600 PERC 4 SCSI Drives, 1 standalone 3 in a RAID 5 configuration OS: Windows 2000 Server In other words, a fairly old system. Anyway, we are in the process of taking over support for this site. The current tech wants out and is fading from view fast, so we need to solve this problem: The standalone disk (where the OS was) failed. We've replaced the disk, installed the OS, but need to know exactly how to proceed from here. I've never worked with a RAID system before, so I don't want to touch anything without knowing what I'm doing. We are not certain if the site will want us to attempt to recover the array or wait for the old tech to become available. We have replaced the server with a temporary box, and recovered MOST of the data from an online backup service. However, the other tech failed to backup a part of the data and the only copy of it is on this RAID array. Hence, our caution. We have poked minimally around in the boot-up PERC config utility, and it seems to me that that's where we'll need to be to reclaim the array. Another possibility is that there is some Dell software for the RAID controller we need to acquire. Can anyone provide clues as to how to proceed from here? Any help GREATLY appreciated.

• Citrix Performance monitoring

  - by Dr I

  Hi people, I has a strange thing which appears on my Citrix Farm today. My users are equiped with a Thin client Axel Model 80F, and today, one of them sustained a problem on it. He opened a citrix's Publish Desktop session (Host by a farm of Windows 2003 R2 SP2 Servers), he loaded Lotus Notes and a mail who contained an PDF attached file. Once he has opened his PDF File, his session has freezed. We've just reboot the Thin Client, and log in again on the session (which hasn't been closed during the process). Once we have log in again, we try to read the pdf and once again afer half a page the session freeze again (I can see the mouse moving on the screen but can make anything). Then I close the session, reboot correctly the thin client, and "Tada" with the same manipulationsn averything is correct and we don't facing any freeze. Well Now my question is: Is that bug came from the thin client or the server about you? I've checked on my farm and I don't have any alert from the Citrix's Monitoring console logs. According to me it's due to the Thin Client BUT I ddon't have enought monitoring tools to be sure of that. So do you have some quite godd monitoring tools or method? My config: Windows 2003 R2 SP2 Citrix Xenapp 5.0

• DrayTek 2820 configuration using public IP addresses

  - by Kev

  I have a /29 range of public IP addresses assigned to me by my ISP. I'm trying to configure a SIP VOIP handset to register with my VOIP provider who recommend using public IP addresses rather than NAT. I have a DrayTek 2820 router flashed with the latest firmware and have configured my router as per DrayTek's FAQ at: How do I use a public subnet on the LAN (non-NAT operation ) ? My IP range is: xx.xx.94.16 -> xx.xx.94.23 This gives a usable range of: xx.xx.94.17 -> xx.xx.94.22 My router's public IP address is: xx.xx.94.17, the SIP VOIP handset is allocated xx.xx.94.18. I have a second internet connection and via that I can ping the handset. However for some reason I can't seem to get it to register with the provider. I tried adding a new Firewall filter to pass through from WAN to LAN: Source: ANY, Destination: xx.xx.94.18, UDP - Ports 1024 -> 65535 Out of interest I also tried opening port 80 to see if I could browse to the phone's admin web interface but no joy. I know that my ISP aren't blocking inbound service ports because I NAT Port Forwarded port 80 to one of my internal web servers and it rendered a test page I had set up. All the NAT settings are reset to factory defaults, i.e. there are no Port Redirection, DMZ Host, Open Ports or Address Mappings configured. The handset I'm using is a GrandStream GXP-2000. Is there anything else I should be doing?

• Automate Windows 7's file sharing and firewall settings

  - by nhinkle

  I am working with my school to customize Windows 7 on some new laptops we are receiving. The laptops come with Windows 7 Professional already installed, and we do not need or want to reimage them. We would however like to customize the installation once it is in place, through a series of scripts. We will also be deploying these scripts to computers which have already been set up. Most of the settings we wish to change can be done easily from the command line or with a registry file. However, there is one thing we keep getting hung up on: networking options. Is there any unattended way to set the Windows 7 networking configuration? We would like to set the following things automatically, which are found under Control Panel > Network and Sharing Center > Advanced sharing settings > Home or Work network: Turn on network discovery Turn on printer and file sharing Turn off public folder sharing Turn on password protected sharing Use user accounts and passwords to connect to other computers We also need to configure the firewall to allow the following exceptions: File and printer sharing Remote assistance Remote desktop Remote scheduled tasks management Remote service management Windows remote management I've looked around, and can't find any way to change these things - I looked into netsh, registry settings, and even used RegMon to watch while I changed the values manually, all to no avail. Google hasn't offered up anything helpful so far. If anyone could provide some insight, I would very much appreciate it. I did find out that much of this is configurable with group policy, but because these computers are in a workgroup, not a domain, I don't know of any way to take advantage of that in an unattended manner.

• How do you host multiple public facing websites on a VPS?

  - by pedroarvy

  We host about 30 websites using typical shared hosting plans using ASP.NET and SQL 2000/2005/2008. I am now wondering about hosting all of these websites using our own virtual private server. This is clearly cheaper but comes with a lot of questions I need answers to: Is the risk of having to keep this VPS server up and running worth it? Until now, the host provider has managed the server and we have not had to worry about crashes, downtime, software patches etc. We are not server administrators, we are programmers, so this is not really our expertise. On the other hand, it may not be hard to learn. When we make a website live, we log in to a domain management control panel and change the primary and secondary name servers to point to our shared web host: Eg ns1.sharedwebhost.com and ns2.sharedwebhost.com These name servers are going to have to change when we have a VPS. I don’t understand anything about how to set this up. Is there some useful info anyone could direct me to? Or is there software we need to install to make the primary and secondary name servers work on our VPS? The control panel we have for shared hosting comes with DNS management like this: http://www.yart.com.au/stackoverflow/dns.png What software would I need to install to create this for each site we host at a VPS? The control panel we have for shared hosting also comes with a POP email interface that allows email addresses to be added easily by our customers. Is this something that can be easily set up at a VPS so clients can manage their own email addresses? Is there software we need to install to make this work?

• Upgrading Ubuntu 9.04 to 9.10 when Update Manager doesn't let you

  - by nickf

  I've been trying to upgrade my installation of Ubuntu 9.04 to 9.10, but all of the instructions I've found haven't been helping. They mostly say to run the update manager and it'll tell you that there's a new distribution ready. Well, mine doesn't say that. Things I've run or checked: update-manager -d says: Your system is up-to-date The package information was last updated less than one hour ago. I've set it to get all new distributions, not just LTS $ cat /etc/update-manager/release-upgrades [DEFAULT] # default prompting behavior, valid options: # never - never prompt for a new distribution version # normal - prompt if a new version of the distribution is available # lts - prompt only if a LTS version of the distribution is available Prompt=normal I'm definitely running 9.04 $ lsb_release -r Distributor ID: Ubuntu Description: Ubuntu 9.04 Release: 9.04 Codename: jaunty Even running the release upgrade from console doesn't help: $ sudo do-release-upgrade Checking for a new ubuntu release No new release found This is running from behind a proxy, but I've set it up such that the regular upgrades and apt-get etc doesn't complain. (export http_proxy=http://myuser:mypass@myserver:8080/) Could you think of anything else which might be stopping me from upgrading?

• Windows or Linux for VPN-VPN Bridge

  - by James

  I have the following network layout: Network1 ----VPN1-----Network2----VPN2----Network3 I can administer everything in Network1 only and my goal is to get to a box on Network3. I've been told by the admins of Network2 that it's not possible for them to route traffic from Network1 to Network3. I've finally been authorised to host a box in Network2 and I'm hoping with this I can set something up to resolve the issue. My question is should I set this up as a Windows or a Linux box. My initial thought was to use iptables to reroute requests but with my lack of experience with Windows Server (used for something or other in Network2) I'm not sure if this will work. My head's full of questions like: - can I get an ip without logging in to a windows domain? - if I do get an ip, do Windows Servers manage routing through the VPN? - can I make a linux box authenticate with Windows Server to log on to the domain? - would it just be easier to set up a windows box? - is it possible to configure a windows box to do routing from Network1 to Network3? Has anyone done anything like this before? Had experience managing Windows Server? Authenticated (or not as the case may be) to a Windows domain? I'd really appreciate your advice. It might be worth mentioning that the overall objective is to establish a telnet connection from a box on Network1 to a box on Network3.

• Mod_Proxy_AJP set up issues

  - by TripWired

  I'm trying to set up Tomcat behind Apache using mod_proxy_ajp. After tons of messing around with the configs I am stuck at a 403 page when trying to access tomcat. I had a 404 before but apparently something I changed along the way fixed that. I'm not sure which setting to change at this point. Could anyone look over the configs I have and see if anything is missing. httpd.conf <IfModule mod_proxy.c> ProxyRequests Off <Proxy *> Order deny,allow Deny from all Allow from localhost </Proxy> proxy_ajp.conf LoadModule proxy_ajp_module modules/mod_proxy_ajp.so # # When loaded, the mod_proxy_ajp module adds support for # proxying to an AJP/1.3 backend server (such as Tomcat). # To proxy to an AJP backend, use the "ajp://" URI scheme; # Tomcat is configured to listen on port 8009 for AJP requests # by default. # # # Uncomment the following lines to serve the ROOT webapp # under the /tomcat/ location, and the jsp-examples webapp # under the /examples/ location. # ProxyPass /tomcat ajp://127.0.0.1:8009/ ProxyPassReverse /tomcat ajp://127.0.0.1:8009/ ProxyPass /examples/ ajp://localhost:8009/jsp-examples/
