So, I recently installed synergy because I was tired of using two mice and keyboards. Problem is, set up is not working. First, the setup.
Server:
Desktop
Windows 7 64 - on our home network, part of Workgroup: WORKGROUP
Client:
work issued laptop
Windows XP SP2 32 - on home network, part of workd Domain: DOMAIN
Server is set up, all the computer names are correct. I'm a bit of a noob at networking things, and I don't want to mess up the configuration of my work laptop again (I already switched the domain to my workgroup, BAD). So, any suggestions that aren't too crazy please, since it's a company laptop.
I've tried putting in the ip on the client as well, firewall is allowing on the port in use, just can't get it to work. I think I'm SOL with the Workgroup/Domain difference though...
From what I remember, Synergy doesn't care about the workgroup and/or domain, it just needs to be able to communicate with the server/client IPs. Did you try to manually insert IPs of client/server?
In a very similar situation I discovered that when trying to ping my non-domain desktop with its workgroup name the dns resolver was appending the work domain to the desktops name. So when I tried synergy with an IP address I successfully connected the two computers.
The only caveat I can offer is maybe you needed to add the application to the windows firewall exception list for both machines. I would assume the port setting was the same between the two computers (default is 24800) in which case you should only use the IP address because the application knows to access 24800 via that setting in the advanced configuration.
You can add the program to the whitelist or specifically the port if you prefer via the Windows Firewall. On a side note - I am also using an older version of synergy (1.3.1) and not the latest as of this answer (1.4.2 Beta) which did not work for me, but I will assume it's because my server was running 1.3.1.
I chose not to update all 6 machines and their respective horrific configuration constructs that synergy loves to enforce upon us. [caution... rant: x is left of y and y is right of x... really? are you sure about that Einstein? Synergy could at least INFER that bit of logic instead of REQUIRING it!]
Hope that helps.

I'm searching for a solution to work on a Windows machine with multiple NICs/networks. While working within the network of a customer I tend to get a lot of problems. I need an internet connection for several things like git/sourcesafe/development system etc. but clients often can't offer internet access. So the solution is to use a mobilephone to connect to the internet and ethernet to access the client network/database.
Windows seems to be pretty random here. Sometimes everything works, some mintues later it trys to access the internet over the clients gataway or access the database via the internet. So I end up deactivting/activating NIC's all day long.
Is there some easy way to use the ethernet connection only to access the clients network and the mobile for everything else?
From what you described I think this might help: turn off DHCP for the interface that connects to your customers network and set a static address for that (without a gateway). Then configure your other interface to use DHCP. This should set ONE default gateway (your phone) and all traffic will run through it, except endpoints in your customer's net.
BTW: You can only have one default gateway at a time, of course, but in your case the gateway that was set the latest won, so to speak.
I have a VMWare Player (Workstation 9 )virtual machine on an Ubuntu 12.10 (13.10 Kernel) host running Ubuntu 12.04 using a bridged connection and set to replicate the physical network connection. Everything usually works properly in a variety of locations. But at one location that I often frequent, the ip address of the virtual machine changes roughly every 10 minutes -rendering the vm entirely useless as it is a postgresql server and thus needs a dedicated local ip. Not only that, but when I copied a database dump into a shared folder, the file ended up getting corrupted.
I can verify that the network caused this problem, as the actual on the vm was not corrupted. I managed to temporarily solve the problem by going into a local modem and setting a DHCP Mac Address. Everything was working and files were not getting corrupted. However, it only lasted temporarily, and another random address was assigned, breaking several running processes on my machine. Between the router/gateway, there is a redundant apple router involved in the network that is likely causing the issue -but I cannot just throw it away or deactivate it, as it is not my network
Furthermore, DHCP leases work just fine for every other machine on the network; so
I believe the root issue is with vmware.
I have no clue what could possibly cause something like this to occur, as IP address assignment is one of those things that normally "just works". I am thinking about just switching to VitualBox, as I have used it in the past and never had a problem (except with properly running Windows 8. However,I have never actually seen any article suggesting VirtualVox over WMWare, as the latter supposedly performs better and has more intuitive shared folder support. Obviously though, any benefit from a shared folder is negated if it just shares corrupt garbage.
So you manually set a MAC address on your VM? In the past, I've seen VM's change MACs quite often; generally only after a reboot or cold start. It shouldn't happen on the fly... You could install Wireshark and grab a few packet captures to see if anything in there points you in the direction of the root cause.
i want to read MAC address of machine from Adobe AIR. I am using flex 3 and AIR 2.
how can i do this
the main purpose is i want to install that product in only one machine
var ni:NetworkInfo = NetworkInfo.networkInfo;
var interfaceVector:Vector.<NetworkInterface> = ni.findInterfaces();
Taken from the Network Info sample in the desktop version of Tour de Flex.
As far as I can tell, you cannot do it with Flex/AIR alone - you can however use the NativeProcess API to communicate with a Java/C program that can do this for you.
If you want to limit your application to just one machine, why don't you just install it manually without giving away the setup file - is it a remote machine? Even in that case you should be able to do a remote installation, right?
The answer "track the combination of IP address and user ID" won't satisfy my (very similar) needs. If the (laptop) computer is moved across WiFi domains, its IP address will change. If the computer is on a commerical IP provider, the IP address can often change without warning or notice.
My users don't want to deal with such problems. They don't even want to know that these problems exist!
The binding of MAC address and user ID can be done at installation time. It's not perfect, but it's pretty good.
Of course what we need is an implementation of public-private key...

Hi Guys I'm debugging some CS program and to view the performance of the application in slow internet I tried many different ways. However the best would be the Server and the client be in the same PC ---- my debugging environments for both the server side and the client is setup in one PC.
So I'm wondering is there anyway to limit the speed? I'm using TCP but I don't know too much in-depth knowledge of it.
Thank you
There are two important factors regarding a "slow" internet connection that you need to test out since they have different implications for your application: bandwidth and latency.
If you provide some more details about what os you are running your tests on, it would be easier to recommend a way to limit the network performance.
On a related side note, it's generally a bad idea to performance test any kind of networking using the loopback device on your machine, since many aspects of this will perform very different than the regular network device on your machine.
You mention in the comments this needs to be done on windows, while the Network Emulators I know of (e.g. netem, TCN, other variants) all require Linux. So one thing you could do is create a virtual machine (VirtualBox is fine, I did similar things with it), install linux on it, configure 2 network interfaces, emulate the slow/long/lossy/jittery network between them, and route the test traffic through it from windows.
Finally I found this does what I need.

I am presently running several websites and a mail server from my home network. I have a business DSL account with 8 public IP addresses (1 by itself, and 7 in a block). To handle routing/firewall/gateway, I am presently using RRAS, DNS, & DHCP from Windows 2003 running on a ancient (circa 2001) PC -- which I suspect is going to fail any time now.
What I would like to do is replace that with a simple router. Have a consumer model LinkSys Wifi-router, which I'm presently just using as an access point (don't have the model number handy, but it's one of their standard models). It seems to be able to handle all the NAT/firewall/DHCP tasks -- except for handling routing the multiple public addresses. (e.g., I need x.x.x.123, port 21 getting to one machine, but port 80 of x.x.x.123 & x.x.x.124 to going to another, and x.x.x.123, port 5000 to still another etc).
So my questions are:
Can this be done with standard Linksys router, which they just don't explain in the consumer manual?
Can this be done ... if I replace the firmware with a community/OS version (and if so, which one?)
If neither of the above, can someone recommend a profession router (preferably with wifi) that does do this, which is close to a consumer level price point.
Alternately, is there a reliable OS/3rd party replacement to RRAS which handles this (since RRAS is the part causing the most trouble)
Alternate-Alternately, can someone point to a VERY simple HOWTO to doing this (ie. follow these steps and forget about it), to installing a LINUX system to do this) (since I assume I can run Linux longer on the old machine)?
This can't be done on a Linksys router with stock firmware. It can be done if you load a third-party firmware, but there's no GUI (afaik) to accomplish it, so you'll be hacking system shell scripts which is pretty hairy. I would recommend getting a low-power or older PC and installing PFSense.
PFSense is an open-source router appliance OS distribution with a very easy to use web front end.
Install DD-wrt On your linksys box. I believe this will have everything you need link text
