3. Do you provide a Windows exe client? Yes, you can download a Windows exe client.
The advantages: it can save chat log to user's hard drive. It's also perfect to online live supporters because it can locally connect to the chat server, and with two Windows clients activated in the system tray, both the monitor window and the chat window are placed in the Windows client instead of in the browser, so that you won't be diverted to other webpages by mistake. You can also offer this exe client to your members to free download, so that they don't have to visit your website to chat with other members, just follow the instructions in the Windows exe client download package to configure it for your own use.

6. Why does my flash client keep loading? Please make sure you have located the "lang" and "skin" folders into the right directory you've defined in client.xml.
7. Why doesn't my logo appear? First check if the logo exists in the skin folder you've chosen.
The logo can only be jpg or swf format, not gif or png, and not bmp either. For jpg logo, make sure it's in non-progressive mode. If not, please use a software like acdsee to convert it. eg: open your jpg in acdsee, then File -> Save as, choose options in popup dialog and in the option of encoding, DON'T check Progressive, then save jpg. Done.
8. How does the flash client support firewall? 123 flash chat client communicates with server via TCP protocol. It use a specific port(which can be either lower or higher than 1024), add a rule in your firewall server to allow access. If the end users are behind firewall, he can open your specific port of his firewall(outgoing port)to access chat. 123flashchat current version now support 80 port, which is allowed by most of the firewall but needs flash player 7 support. Details here>>
9. How to bind 80 port? Of course you can bind chat server 80 port, but you have to make sure you still have free 80 port. As we know, http server is always binded on 80 port, so if you have any http server like IIS or Apache,
80 port will be taken by default, that's why you failed to start chat server on 80 port, cause it's already used.
Here is the solution: If you have only 1 ip address on your server and 80 port must be bound on web server,
then there is no way to bind 80 port on chat server, too.
But if you have 2 or more IPs in your server, you can do it this way:
bind 80 port of one IP on web server, then bind the free 80 port of another IPs to chat server. For example, you have 2 IPs:
1.2.3.4
9.8.7.6
and you installed apache on your server.
(You can find all your IPs with the command: "ifconfig -a" )
1). please edit httpd.conf (apache configuration file)
Listen 1.2.3.4:80
(Don't use "Listen 80" , it will use all 80 port on every IPs)
restart the web server, then you have the free 80 port on 9.8.7.6
2). edit 123flashchat configuration file: fcserver.xml
restart the chat server, then you can use 80 port!
for IIS web server, it's the same. PS: If your server is Unix/Linux OS, you have to login to root account first to bind the 80 port, because only root account can bind the port lower than 1024.
10. My server runs Freebsd, can I install 123 flash chat server on it? Since freebsd doesn't have official java support, freebsd is not very compatible with java.
123flashchat uses SUN jdk new nio, even with SUN jdk installed, even though you can install 123flashchat on your Freebsd, it can't be very stable. We've tried hard to resolve this problem but so far there isn't any satisfying solution. We strongly recommend linux server.
because we've done a lot of high-load test on linux server, the performance of 123flashchat on linux is very superb.

11. Can I install 123 flash chat software without a server? Unfortunately you can't run chat server without a server, but you can consider our affordable chat server hosting plan.
12. What's the bandwidth necessary for running 123 flash chat server software? 123flashchat uses much less bandwidth than ordinary chat softwares because it's based on TCP socket communication, instead of refresh technology.
The bandwidth required by the chat server depends on the number of concurrent chatters and the frequency of chatting. ex: for 20 people in one room and 1 message sent by one of the users every 10 second,
if the average size of messages is 100 bytes, then the server needs a bandwidth of (20 messages sent to users every 10 seconds)*100 bytes/10 s *8 = 1.6 k bps.
That means if you have about 20 people chat a lot in your chat room,
Bandwidth per day: 86400 x 1.6 k =135M
Bandwidth per month: 135 X30 =4.05G
You can see usually you don't have to worry about bandwidth with 123 Flash Chat.
13. Why "connection failed"?First of all, did you install the chat server on a dedicated server or at least a VDS/VPS? Because only ftp authority on a shared hosting is not enough to run java application on server. If unfortunately you can't host the chat, we offer cheap hosting service: http://www.123flashchat.com/host.html 1) Please check if your chat server already started.
2) Check your client.xml to make sure host value is correct,
it should be in the url string , after "http://"and before the first "/".
eg: your url is http://aaa.bbb.com/ccc/chat.html ,
then the hostname should be "aaa.bbb.com".
3) If still a problem, please check if your firewall has open the port 51127.
4) still not work? then send us the chat URL, we can help to check it out.

To fix that , you need make sure the version of license and chat installation package to be the same and restart the chatroom server. |
