2176 - How To Enable Ports On Wireless Network For Java Socket Programming
Apr 10, 2012
I have written a java server-client program. The server accepts incoming connections on port 2175 and writes responses on 2176 which the client listens on for the response. I am sending serialzed objects over the network.
Problem: This all works well if I run my client on the same machine as the server. I put together a client jar and deployed it on another machine running on the same wireless network as the server. Now I get a "ConnectionException :Connection refused". So I thought I should hardcode the server and client IP's but that still didnt work.
Question: What else would I have to do to get the two computers to talk to each other (in terms of networking not java)?

What is the difference between networking and network programming? Is it the same? If no, then does networking involve programming using languages such as c++ and java? Im thinking of doing a networking course and I don't know basics in any computer languages such as C++, Java and stuff. Can the course be done w/o any knowledge of languages I mentioned above whatsoever?

I have a problem with my AP. Basically when I plug it in to the PoE switch it will start up (I can see the lights) but for some reason there is no light on the PoE switch. Looks like there is nothing connected. I chave changed the cable, port on the PoE switch but still the same. Is it possible that maybe few pins on the RJ-45 socket are demaged or there may be sth else.The other APs start without any issues and the light is always on on the PoE switch.I also need to add that the AP can not get the IP address.

I have a tcp socket server application. Some of my clients are asking if I can provide server redundancy for my tcp service for HA purpose. I know it can be done using Windows NLB but the cost of the Enterprise edition is beyond the budget of most of my clients. DNS failover is also out since it will involve fiddling with the DNS server. I'm would prefer to setup a simple solution in which I check the status of the primary server and then if the primary is down, change the ip address of the secondary to the primary so that the service remains available. This sounds simplistic, and besides different clients use different networks, e.g. AD, but I'm not a networking guy so I am at my wits' end.

I am working on a friends HP laptop that suddenly lost it's ability to see any networks at all. When I try to enable it in network and sharing it stays disabled. Just to be sure it wasn't hardware related I ran a ubuntu live cd and was able to connect with no problems. I tried updating the drivers,installing and reinstalling the network card with no luck. I also tried letting windows repair it but it says there may be driver problems.

However, when I right click into it and try to Enable, it shows that it is now Enabling.... then Enabled but after that my "Wireless Network Connection 2" still Disabled.I had already uninstalled my AVG Internet Security 2012 and disabled Windows Firewall and Run in Safe-Mode in installing the driver but still no luck it keeps showing that my "Wireless Network Connection 2" still Disabled after trying to Enable it.

I have had my WRT610N for several years and I noticed the other day that my network was not locked. I went to task/change wireless connection and clicked on it. The next screen gives me two options: " Wireless Security" or "Network Lock" and under network lock it states "Network Lock: Not enabled". I then click on the enable network lock button and I get the following message "network lock could not be enable." No matter howmany times I do this I get the same message. So, why is Network Majic not letting me lock my network? It has always worked before and just recently did this. I have done a factory reset on my router to see if this could be the problem, but i still get the same message.

I cannot enable the wireless network connection. Here's what I have: In Network Connections I have two network connections, the Local Area Connection (wired ethernet), and this works fine without a problem, and I have the Wireless Netwok Connection. The Wireless Network Connection is greyed out and says that it is "Disabled". When I right click on it and click on Enable a small window pops up and say "Enabling", then is says "Enabled", but the Wireless Network Connection is still greyed out and says "Disabled".
1. When I click on the Dell Wireless WLAN Card Utility I get the message: "There are currently no wireless adapters available and enabled. Please enable any available wireless adapters before accessing this configuration utility".
2. In the Device Manager the Dell Wireless 1701 802.11b/g/n can be found under Network adapters. There is neither a red or yellow icon next to it. When I click on properties for this I am told that this device is working properly.
My OS is windows 7 32 bit and my laptop is dell inspiron N4110.

(does not work) connecting thou CD. I was given a msg telling me to disable my 'other' wireless manager and use the windows wireless manager to connect (i have no idea i had 'Other' Wireless manager >.>) testing whither or not the same adapter works on another PC (it works...) Testing wither or not my router is not working... (well.. im typing right now... so it works...)

What's the least expensive way to enable Guest Network authentication in a network with WLC 4404 controllers and no WCS? Management would like guests to register with a valid email address and enter a 'password du jour' to keep unauthenticated users from chewing up bandwith with automatic connections.

My house is wired with Ethernet to just about every room with several connections in some rooms and its come time to expand our network. Right now we have a wireless router connected by Ethernet to a standard Ethernet router and we are experiencing problems with our network printers. While i'm not sure if it will solve our printing problems i am looking to consolidate both my wireless router and my standard Ethernet router into one single router.

basic question regarding the switchports on the rear of the 2106 controller. How do I configure them for use? I'm using port 1 as my uplink to a trunk port on an ASA and my network traffic to the management interface and guest vlans is all working as expected, but when I plug anything into any of the other ports, they get no addresses from my dhcp server (the ASA). I see nowhere to configure which vlan to tie the ports to or anything. I suppose I'm more used to a catalyst or ASA where I can just pick the ports and vlans (or trunks) I want to attach them to. [code] Again, all of the existing network functionality (private and guest network) is all functioning fine so I'm pretty confident I have the above configured correctly, I just cant make any progress on the WLC ports 2 - 8.

Recently, I've been having some problems trying to play a couple games coded in Java, such as MineCraft. Every time the game loads, my internet immediately disconnects.There isn't any error dialogue or message, it simply disconnects me.Sometimes, I am able to stay on my internet connection and play the game for a short while, but most of the time, it disconnects me. I am on a wireless connection, with a router running the custom DD-WRT firmware.

I'm installing a new platform LMS 4.0.1 under VMWare and Windows 2008 R2.
I installed via Windows 2008 R2 Patch without problem in LMS 4.0, then updated in LMS 4.0.1.
I'm facing several issues during this installation.
The first issue I have is the following:
When I launched topology services, java jre file jre-6u22-windows-i586-p_withjacorb.exe was downloaded and I saved it on disk.
I clicked on file to install it and get the following message during the installation:
Error 1330.A file that is required cannot be installed because the cabinet file C:UserslmsAppDataLocalLowSunJavajre1.6.0_22Data1.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt.
It tried to install certificate without success. I have internet access to java.com but it seems publisher is not trusted.
