• IIS 7: One Page Works, All Others Fail With "Error code: ssl_error_rx_record_too_long"

  - by Michael

  On my local machine, I have a second site bound to Port 81. Within that site is a certain page which I can browse from other machines with no problems, but all other pages fail with "Error code: ssl_error_rx_record_too_long". Each of the failing pages (as well as the lone working page), works with localhost. So, from any machine, local or remote: http://cmwmach01.mydomain.biz:81/RD/SS/SS.aspx (works) http://cmwmach01:81/RD/SS/SS.aspx (works) http://cmwmach01.mydomain.biz:81/RD/POV/SC.aspx (fails - gets changed to https) http://cmwmach01:81/RD/POV/SC.aspx (fails - gets changed to https) Everything works with localhost (locally, of course). I've tagged this question with SSL because, at one point, it would warn about an SSL cert issue (maybe this was self-signed at one point?), but now it doesn't. While there may be an issue around that, I don't see how this could cause the issue I am seeing (but, as I mention below, am I way out of my depth here). I am way out of depth here in trying to figure out why that one page works (or the others don't), so that I can make them all work. Any ideas?

• How to access Virtual machine using powershell script

  - by Sheetal

  I want to access the virtual machine using powershell script. For that I used below script, Enter-PSSession -computername sheetal-VDD -credential compose04.com\abc.xyz1 where, sheetal-VDD is hostname of virtual machine compose04.com is the domain name of virtual machine and abc.xyz1 is the username of virtual machine After entering above command , it asks for password. When the password is entered I get below error, Enter-PSSession : Connecting to remote server failed with the following error message : WinRM cannot process the reques t. The following error occured while using Kerberos authentication: There are currently no logon servers available to s ervice the logon request. Possible causes are: -The user name or password specified are invalid. -Kerberos is used when no authentication method and no user name are specified. -Kerberos accepts domain user names, but not local user names. -The Service Principal Name (SPN) for the remote computer name and port does not exist. -The client and remote computers are in different domains and there is no trust between the two domains. After checking for the above issues, try the following: -Check the Event Viewer for events related to authentication. -Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or us e HTTPS transport. Note that computers in the TrustedHosts list might not be authenticated. -For more information about WinRM configuration, run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting Help topic.

• RewriteRule causes POST data to get dumped before I can access it

  - by MatthewMcGovern

  I'm currently setting up my own 'webserver' (a Ubuntu Server on some old hardware) so I can have a mess around with PHP and get some experience managing a server. I'm using my own little MVC framework and I've hit a snag... In order for all requests to make it through the dispatcher, I am using: <Directory /var/www/> RewriteEngine On RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|bmp|gif|css|js)$ [NC] RewriteRule . HomeProjects/index.php [L] </Directory> Which works great. I read on Stackoverflow to change the [L] to [P] to preserve post data. However, this causes every page to return: Not Found The requested URL <url> was not found on this server. So after some more searching, I found, "Note that you need to enable the proxy module, and the proxy_http_module in the config files for this to work." The problem is, I have no idea how to do this and everything I google has people using examples with virtual hosts and I don't know how to 'translate' that into something useful for my setup. I'm accessing my webserver via my public IP and forwarding traffic on port 80 to the web server (like I'm pretending I have a domain/server). How can I get this enabled/get post data working again? Edit: When I use the following, the server never responds and the page loads indefinately? LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so <Directory /var/www/> RewriteEngine On RewriteCond %{HTTP_REFERER} !^http://(.+\.)?82\.6\.150\.51/ [NC] RewriteRule .*\.(jpe?g|gif|bmp|png|jpg)$ /no-hotlink.png [L] RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|bmp|gif|css|js)$ [NC] RewriteRule .

• Workaround for Dell "Power Supply Not Recognised" issue

  - by Haedrian

  So, I have a Dell Inspirion and the power supply port appears to be damaged. Basically when I plug it in I get a nice popup telling me that it couldn't detect that its a Dell power supply so it won't charge the battery and underclocks the system. It still works for other purposes (that is, giving power) I thought it was the actual power supply cable so I bought a new one, that worked for a while, provided I inserted it at JUST THE RIGHT angle. But now that's not working anymore, so I assume its the part which connects to the computer. The battery charging I can live without, the underclocking I can't. I'd like a way around this issue. Things I've tried: Updating the BIOS Replacing the power supply cable Inserting it at different angles Turning it off and on again Swearing at it Twisting it while inserting it So, is there a workaround somehow? I'd like to avoid taking out my soldering kit and risking permanently damaging expensive equipment if that's allright. I'm hoping for a software solution. Added: The exact model is a Del Inspirion N5010

• How to connect android client to the localhost of Apache server (php) inside my laptop?

  - by user1796310

  I'm trying to create android apps which able sending data through wifi connection to my laptop Apache Server and MySQL database. I use the samsung galaxy tab 10.1 as my mobile device. and the protocol i used is HttpGet or HttpPost. And i use XAMPP( with Apache& SQL) to do the server and process the php. But, due to android cannot detect adhoc network from laptop, i use Virtual Router ( for window 7) to create virtual access point and make the tablet able connect to my laptop. But the problem is: [1] in my apps (client-android), where the httpget or httppost to which url? localhost in my laptop- 127.0.0.1 or localhost in android 10.0.0.1? or the ip address of the virtual router? [2]so, if i want access from android to the localhost(laptop-Apache) to call the php to run? which port? which ip address /url that i need to put in android apps(httpget)? and do i need to modify anything in httpconfig for XAMPP? thanks alot.

• Outbound ports to allow through firewall

  - by dunxd

  This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support commonly required resources: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working. I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

• If I run two monitors from two different graphic cards, can I still have Twinview?

  - by rumtscho

  I am planning to get a second 2560x1440 monitor for home. The trouble is, I only have 1xDVI, 1xVGA on my graphics card (a 250 GT). I don't want to buy a new graphics card until the prices for the 500 series have stabilized, so probably not before summer (or will it happen earlier? I don't remember how it was for other series, and I couldn't find long-term price history for video cards). The solution I had in mind is to get the 7600 GS from my old PC, which also has 1xDVI, 1xVGA, and run each monitor on a separate card. I have never done that, and I was wondering 1. If I will be able to run the monitors in Twinview then, or will I be stuck with separate X sessions, and 2. Whether there are some other disadvantages as compared to a single-head graphics card. (I am using the proprietary driver because I need compiz). As an aside, how do I find out whether the DVI port on the old graphics card is dual link?

• Allow connections to only a specific URL via HTTPS with iptables, -m recent (potentially) and -m string (definitely)

  - by The Consumer

  Hello, Let's say that, for example, I want to allow connections only to subdomain.mydomain.com; I have it partially working, but it sometimes gets in a freaky loop with the client key exchange once the Client Hello is allowed. Ah, to make it even more annoying, it's a self-signed certificate, and the page requires authentication, and HTTPS is listening on a non-standard port... So the TCP/SSL Handshake experience will differ greatly for many users. Is -m recent the right route? Is there a more graceful method to allow the complete TCP stream once the string is seen? Here's what I have so far: #iptables -N SSL #iptables -A INPUT -i eth0 -p tcp -j SSL #iptables -A SSL -m recent --set -p tcp --syn --dport 400 #iptables -A SSL -m recent --update -p tcp --tcp-flags PSH,SYN,ACK SYN,ACK --sport 400 #iptables -A SSL -m recent --update -p tcp --tcp-flags PSH,SYN,ACK ACK --dport 400 #iptables -A SSL -m recent --remove -p tcp --tcp-flags PSH,ACK PSH,ACK --dport 400 -m string --algo kmp --string "subdomain.mydomain.com" -j ACCEPT Yes, I have tried to get around this with nginx tweaks, but I can't get nginx to return a 444 or abrupt disconnect before the client hello, if you can think of a way to achieve this instead, I'm all ears, err, eyes. (As suggested by a user, bringing this inquiry over from http://stackoverflow.com/questions/4628157/allow-connections-to-only-a-specific-url-via-https-with-iptables-m-recent-pote)

• iptables rules to allow HTTP traffic to one domain only

  - by Zenet

  I need to configure my machine as to allow HTTP traffic to/from serverfault.com only. All other websites, services ports are not accessible. I came up with these iptables rules: #drop everything iptables -P INPUT DROP iptables -P OUTPUT DROP #Now, allow connection to website serverfault.com on port 80 iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT #allow loopback iptables -I INPUT 1 -i lo -j ACCEPT It doesn't work quite well: After I drop everything, and move on to rule 3: iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT I get this error: iptables v1.4.4: host/network `serverfault.com' not found Try `iptables -h' or 'iptables --help' for more information. Do you think it is related to DNS? Should I allow it as well? Or should I just put IP addresses in the rules? Do you think what I'm trying to do could be achieved with simpler rules? How? I would appreciate any help or hints on this. Thanks a lot!

• How does KMS (Windows Server 2008 R2) differentiate clients?

  - by Joe Taylor

  I have recently installed a KMS Server in our domain and deployed 75 new Windows 7 machines using an image I made using Acronis True Image. There are 2 variations of this image rolled out currently. When I go to activate the machines it returns that the KMS count is not sufficient. On the server with a slmgr /dlv it shows: Key Management Service is enabled on this machine. Current count: 2 Listening on Port: 1688 DNS publishing enabled KMS Priority: Normal KMS cumulative requests received from clients: 366 Failed requests received: 2 Requests with License status unlicensed: 0 Requests with License status licensed: 0 Requests with License status Initial Grace period: 1 Requests with License statusLicense expired or hardware out of tolerance: 0 Requests with License status Non genuine grace period: 0 Requests with License status Notification: 363 Is it to do with the fact that I've used the same image for all the PC's? If so how do I get round this. Would changing the SID help? OK knowing I've been thick whats the best way to rectify the situation. Can I sysprep the machines to OOBE on each individual machine? Or would NewSID work?

• ASA 5505 VPN setup. VPN works but still unable to reach devices in the inside network.

  - by chickenloop

  I've setup a Remote Access VPN on my Cisco ASA 5505. I'm able to connect to my ASA via my phone or the Cisco client, but I'm unable to reach devices in my inside LAN when connected via VPN. The setup is the following: Inside Network : 10.0.0.0/24 VPN_POOL: 172.16.0.0/24 Outside Network: 192.168.1.0/24 ASA is not the perimeter router, there is another device on the 192.168.1.0/24 network which is connected to my cable provider. Obviously UDP port 500 and 4500 are forwarded to the ASA's outside interface. Everything works perfectly, besides the VPN stuff. Config: interface Vlan1 nameif inside security-level 100 ip address 10.0.0.254 255.255.255.0 interface Vlan2 description Outside Interface nameif outside security-level 0 address 192.168.1.254 255.255.255.0 object network VPNPOOL subnet 172.16.0.0 255.255.255.0 object network INSIDE_LAN subnet 10.0.0.0 255.255.255.0 Then the exempt NAT rule. nat (inside,outside) source static INSIDE_LAN INSIDE_LAN destination static VPNPOOL VPNPOOL I don't think that the problem is with the VPN config, as I can successfully establish the VPN connection, but just in case I post it here: group-policy ZSOCA_ASA internal group-policy ZSOCA_ASA attributes vpn-tunnel-protocol ikev1 split-tunnel-policy tunnelspecified split-tunnel-network-list value Split-Tunnel default-domain value default.domain.invalid tunnel-group ZSOCA_ASA type remote-access tunnel-group ZSOCA_ASA general-attributes address-pool VPNPOOL default-group-policy ZSOCA_ASA tunnel-group ZSOCA_ASA ipsec-attributes ikev1 pre-shared-key ***** Any ideas are welcome.

• Can only ssh when not using wifi

  - by AChrapko

  So I have 3 machines, a windows 7 desktop that is always wired to my router, osX laptop, and raspberry pi running debian linux. My router is a Linksys e1000 wireless N. My goal is to be able to ssh the raspi from any machine, while it is connected via wifi. My problem is that when trying to ssh from either the win7 or osX to the Pi it either times out, or gives an error: "ssh: connect to host 192.168.1.### port 22: No route to host" The only times that I have managed to connect to the pi from any machine were when it connected to the router via an Ethernet cable. Currently with win7 desktop wired, macbook wireless, and pi wireless tests give the following: win7 ping macbook: Destination host unreachable. macbook ping win7: Request timeout. win7 ping pi: Destination host unreachable. macbook ping pi: Request timeout. blah blah blah Plugging the macbook into the router with an Ethernet cable all communication between win7 and macbook works. Pings, ssh, ftp, smb ect... No changes to the pi, still no connections possible to or from any of the other 2 machines. Note All machines, are able to connect to the internet and ssh to the same machine on a completely different network, wired or over wifi. Plugging the Pi in with Ethernet (and macbook still wired) I can ssh to the pi from both win7 and macbook. I can ssh from the pi to macbook. All machines still able to connect the the off network machine. Also another little side note- I was playing warcraft 3 with my roommates the other day, and the only time they were able to see my LAN game was when they were plugged into the router with an Ethernet cable. Once or twice one of the laptops was able to connect over wifi, but not without another computer connecting first via Ethernet. So basically does anyone have any info as to why my router seems to completely ignore local wireless traffic?

• How do I serve Ruby on Rails applications on Windows Server 2008?

  - by Adam Lassek

  I have spent the last several hours attempting to get Ruby on Rails running on a Windows server with no luck. At first I tried configuring a test application through IIS7's FastCGI support, but the documentation for this is not very good. I've been following this blog entry, and this one, and this one, and this one but everything seems to be missing major steps, or are out of date. And every article keeps linking back to this Howto from rubyonrails.org that doesn't exist. The sense that I'm getting is that even if I manage to make this work, IIS' FastCGI isn't good enough to use in a production environment anyway. So it looks like my best bet is to setup a reverse proxy in IIS that points to Apache & Mongrel/Passenger using ARR and UrlRewrite. Is there anybody else out there stuck deploying a Rails application on a Windows stack? Am I on the right track? Can you give me a better idea of how to configure this? I believe Plesk already installed an instance of Apache/Tomcat running on this server using a different port, so adding another virtual host shouldn't be difficult; the hardest part seems to be setting up the reverse proxy through IIS.

• Designing a persistent asynchronous TCP protocol

  - by dogglebones

  I have got a collection of web sites that need to send time-sensitive messages to host machines all over my metro area, each on its own generally dynamic IP. Until now, I have been doing this the way of the script kiddie: Each host machine runs an (s)FTP server, or an HTTP(s) server, and correspondingly has a certain port opened up by its gateway. Each host machine runs a program that watches a certain folder and automatically opens or prints or exec()s when a new file of a given extension shows up. Dynamic IP addresses are accommodated using a dynamic DNS service. Each web site does cURL or fsockopen or whatever and communicates directly with its recipient as-needed. This approach has been suprisingly reliable, however obvious issues have come up and the situation needs to be addressed. As stated, these messages are time-sensitive and failures need to be detected within minutes of submission by end-users. What I'm doing is building a messaging protocol. It will run on a machine and connection in my control. As far as the service is concerned, there is no distinction between web site and host machine -- there is only one device sending a message to another device. So that's where I'm at right now. I've got a skeleton server and a skeleton client. They can negotiate high-quality authentication and encryption. The (TCP) connection is persistent and asynchronous, and can handle delimited (i.e., read until \r\n or whatever) as well as length-prefixed (i.e., read exactly n bytes) messages. Unless somebody gives me a better idea, I think I'll handle messages as byte arrays. So I'm looking for suggestions on how to model the protocol itself -- at the application level. I'll mostly be transferring XML and DLM type files, as well as control messages for things like "handshake" and "is so-and-so online?" and so forth. Is there anything really stupid in my train of thought? Or anything I should read about before I get started? Stuff like that -- please and thanks.

• How to get a list of Dovecot IMAP users

  - by Colt McCormack

  How do you get a list of users for a dovecot email server that connect via IMAP (as opposed to POP)? Our server is setup to authenticate via LDAP/PAM. Is there an easy way to get a list of the users who are accessing their mail via IMAP, rather than POP? I am about to migrate our server to Google Apps and want to migrate all of the mail for my IMAP users only (couple hundred out of several hundred total users). POP mail will be migrated separately from the client end obviously. I would much rather migrate only the IMAP users rather than the whole domain which would include migrating a bunch of POP mail left in the server that has already been read/sorted/deleted in the client's email program. Migrating all of that extra useless leftover POP mail could waste weeks of migration time. I suppose parsing some logs to see who has connected on an IMAP port (995 or 993) would give me a list would work if someone could help me do that. I know I have the raw dovecot logs, but am hoping for a cleaner solution.

• How should I configure my Apache Hosts File to serve a different site for localhost than for my domain/publicip?

  - by rofls

  I'm trying to test out a LAMP (with PHP5 specifically) setup with Django already serving a website. I want to do the PHP stuff on localhost for now, so that when I do something like this: curl http://localhost/database/script.php?var=1, I get a response from the php server. Right now I'm getting a Django error. I tried something like this in the default file in sites-available: Listen 80 <VirtualHost aaa.bbb.ccc.ddd> ServerName localhost DocumentRoot /home/phpsite </VirtualHost> where aaa.bbb.ccc.ddd is the local ip address, and changing my actual site's settings to specify the public ip, like this: Listen 80 <VirtualHost www.xxx.yyy.zzz> ServerName mysite.com DocumentRoot /srv/www/mysite WSGIScriptAlias / /srv/www/mysite.wsgi </VirtualHost> but then I start getting all kinds of errors when I start apache, such as port ::[80] is already in use or something. I noticed that the hosts file that's located in /etc/apache2/ is apparently pointing everything to mysite.com, including my local ip as well as 127.0.0.1 and 127.0.1.1; Do I need to change the configuration there too?

• securing communication between 2 Linux servers on local network for ports only they need access to

  - by gkdsp

  I have two Linux servers connected to each other via a cross-connect cable, forming a local network. One of the servers presents a DMZ for the other server (e.g. database server) that must be very secure. I'm restricting this question to communication between the two servers for ports that only need to be available to these servers (and no one else). Thus, communication between the two servers can be established by: (1) opening the required port(s) on both servers, and authenticating according to the applications' rules. (2) disabling IP Tables associated with the NIC cards the cross-connect cable is attached to (on both servers). Which method is more secure? In the first case, the needed ports are open to the external world, but protected by user name and password. In the second case, none of the needed ports are open to the outside world, but since the IP Tables are disabled for the NIC cards associated with the cross-connect cables, essentially all of the ports may be considered to be "open" between the two servers (and so if the server creating the DMZ is compromized, the hacker on the DMZ server could view all ports open using the cross-connect cable). Any conventional wisdom how to make the communication secure between two servers for ports only these servers need access to?

• Have some questions about setting up a VPN to my private cloud servers

  - by Pure.Krome

  I've got a number of Virtual Servers running at a pretty big Cloud provider. They are all running Windows 2008 R2. I have a CISCO ASA firewall in front of them. Currently, I've got all ports blocked except 80/443/21/3386 (for Remote Desktop). I asked to have a VPN enabled on the firewall and they said it's easy to do BUT I need to use the 3rd party Cisco software. Now, I don't want to get into a debate about it .. but we don't want to install anything extra on our -client- computers. We all use Windows 7 and we love using the built in VPN client to connect to other private LANS we have setup in other locations. So i'm wondering what options I have to create a VPN tunnel to our private cloud LAN? All our cloud servers are part of WORKGROUP, so there's no Active Directory .. nor do we want to install all that. Secondly, we know we can open up a firewall port - so any ports for starting a VPN is fine! Lastly, I was thinking of just using one of the existing servers as the VPN server (and using the Windows VPN software) .. but I'm not sure this is a good thing? Remember - we just want to use the baked in VPN software in Windows 7 .. which is PPTP or SSTP or L2TP/IPSEC. I would -LOVE- to use some free OSS software. For usernames/passwords? We'd probably just have one account .. like U:Hithere P:whatever.. so we don't need any hardcore account management, like Active Directory, etc. So does anyone have any ideas?

• How to divert traffic based on hostname using HAProxy?

  - by Bosky

  I've had some initial success with HAProxy setting up a bunch of app servers listening on various other ports. I now have another webserver listening on one port, and i'd like to what changes to make to my config to flow traffic by hostname as well. The following is the current setup, assuming: my apache webserver is running at examplecom:8001 my bunch of app servers 0.0.0.0:8081, 0.0.0.0:8082 , 0.0.0.0:8083 global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 debug #quiet #user haproxy #group haproxy defaults log global mode http option httplog option dontlognull retries 3 redispatch maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 listen appservers 0.0.0.0:80 mode http balance roundrobin option httpclose option forwardfor #option httpchk HEAD /check.txt HTTP/1.0 server inst1 0.0.0.0:8081 cookie server01 check inter 2000 fall 3 server inst2 0.0.0.0:8082 cookie server02 check inter 2000 fall 3 server inst3 0.0.0.0:8083 cookie server01 check inter 2000 fall 3 server inst4 0.0.0.0:8084 cookie server02 check inter 2000 fall 3 capture cookie vgnvisitor= len 32 (any other comments on the ^ setup are welcome.) Now I'd like to continue the same above, but in addition in case - if the hostname is myspecialtopleveldomain<dot>com, then would like to flow traffic to example<dot>com:8001 ~B

• Upstart multiple instances of service not working.

  - by Dax

  I started playing with MongoDB on Lucid. Now I would like to run a DB and Config server on the same box. They both use the same binary to launch, but with different config files and running on different ports. All directories for log and lib is split so one goes to mongodb and the other to mongoconf. Each process can be started without any problems on their own. start mongodb stop mongodb start mongoconf stop mongoconf But if I try to start both, the second one would just start and exit. Using 'initctl log-priority debug' I got the following in the logs. Jan 6 12:44:12 mongo4 init: event_finished: Finished started event Jan 6 12:44:12 mongo4 init: job_process_handler: Ignored event 1 (1) for process 5690 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) main process (5690) terminated with status 1 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) goal changed from start to stop Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) state changed from running to stopping man 5 init shows that you can use instance names to differentiate the two. I tried using 'instance mongoconf' in the on upstart script and 'instance mongodb' in the other one, and it still fails. I can manually start the other process, so there is definitely no conflicts on port numbers or directories. Any ideas on what to try or how to get output on why it is 'terminated with status 1'? Thanx

• Service redirection on same network

  - by Unode

  I have a network on which I run multiple servers each dedicated to a given service. Because most services run on distinct ports I'm currently looking for a way of unifying "all" services into a single "proxy" machine. The idea is to abstract which machine is being accessed but still allow direct connection if needed/requested. This "proxy" machine has only one network interface which is part of the same network as all the other service providing machines. I've looked into Routing and NAT but I've so far failed to figure out how to make it work. I tried to achieve this using shorewall but couldn't find clear examples. However I'm not entirely sure this is the best/simplest strategy. With that said, what would be the best way of achieving this result? Example case: Proxy IP - Listening port - Send requests to 192.168.0.50 80 192.168.0.1:80 " 22 192.168.0.2:2222 " 3306 192.168.0.3:3000 " 5432 192.168.0.4:5432 " 5222 192.168.0.5:5222 PS: I'm not concerned with the single-point-of-failure nature of the proxy. Thanks

• Java games applet not connecting to Yahoo

  - by Steve

  Hi. I am trying to play a Y! game which use a java applet. The applet displays the message: Alert. Unable to connect to server. One of four things could have caused this: 1) You are behind a firewall. 2) You are not connected to the internet. 3) The games server is down. 4) You have a stale page in your cache. I have added an exception to the Windows firewall for java.exe. I am obviously connected to the Internet okay. The games server is not down when I am at home. I doubt it is down when I am at work. I have never successfully loaded this page before, so I doubt I have a stale page in cache. Could it be the corporate firewall? Nothing else in my web browser has been blocked before. Maybe the java applet connects on a different port to the browser. What should I test?

• Issues with returned mail sent to web-based email domains

  - by Beeder

  My company is having issues with returned mail that we send out to external domains. A few weeks ago we replaced a firewall and changed ISP providers and began subsequently having issues RECEIVING emails from external sources because we hadn't updated our new IPs in the DNS records. After making the necessary configuration changes and setting up SMTP forwarding over port 25 to our mail server, everything was working fine up until a few days ago when we started having mail sent out returned to us. We aren't having any trouble communicating internally (to recipients on our domain) but it seems we're having trouble with outbound messages to web-based email recipients. (@hotmail, @live, @yahoo, @gmail...etc) Currently we are running Server 2003 SP2 and exchange 2003. I'm very unfamiliar with configuring Exchange and could really use some help in narrowing down the possibilities. I did some research and am becoming suspicious of Sender ID being the culprit due to our recent IP address change and the likelihood that Sender ID is identifying us as a fake domain. Am I going in entirely the wrong direction? Any input or guidance would be infinitely appreciated. This is the message that is returned when an outbound message fails...this particular one was sent to my @live.com account for testing purposes... Your message did not reach some or all of the intended recipients. The following recipient(s) could not be reached: [email protected] on 5/17/2012 3:02 PM There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. Unfortunately, messages from xx.x.xx.x weren't sent. Please contact your Internet service provider since part of their network is on our block list. I tried a reverse DNS lookup and found that we are set up as a Forward-confirmed reverse DNS. So do I just need to contact my ISP and have them correct their DNS records or is this something I can solve on our end??
