Advanced Troubleshooting
This section contains answers to more advanced questions about using SGImeeting. It covers the following topics:
 |
Using SGImeeting through a firewall |
|
Calling into a Conference Server / Multipoint Conferencing Unit (MCU) |
|
Password-protected conferences |
|
Solving color problems |
|
De-installing SGImeeting |
If your problem is related to interoperation with Microsoft NetMeeting, you may find the support section of the Microsoft NetMeeting web pages useful.
If you are connected to the Internet via a firewall (as is usual in most corporate/LAN environments), you can use SGImeeting to communicate with others located both inside and outside the firewall. To enable full external communication, you need to:
|
Make sure your workstation has its default gateway set to the internal address of the firewall computer. |
|
Configure the firewall to allow primary TCP connections over the following IP ports:
|
|
Configure the firewall to map internal IP addresses to external Internet addresses. (This is not possible with all firewalls. If your firewall cannot do this, you will be able to call out from inside the firewall, but you will not be able to receive incoming calls from computers outside the firewall.) |
If you are unsure whether you are connecting to the Internet via a firewall, consult your system administrator or Internet service provider.
The Microsoft NetMeeting web site contains further help on using NetMeeting through a firewall.
SGImeeting fully supports conferences hosted on Conference Servers, and has been tested with Outreach ConferEase and DataBeam neT.120.
When calling an MCU, specify the address of the MCU as normal. You can also specify the name of the conference to join. If you do not specify a conference name, and SGImeeting detects that the machine called is currently hosting more than one conference, you will be asked which conference you wish to join. Note that hidden conferences will not be included in the list of available conferences: you must specify the hidden conference name when calling into the computer.
See also the section on password-protected conferences.
When you attempt to join a conference that has been designated as password-protected, SGImeeting will prompt you to specify the password.
Some T.120 implementations incorrectly advertise conferences as password protected, even when no password has been specified. In this case, just click OK without specifying a password: the conference will be established as normal.
Note that you cannot create a password-protected conference with SGImeeting.
If you experience problems with color operations (such as text highlights) with Windows applications shared by NetMeeting, try the following remedial steps:
|
If your X Server is running with a Static or DirectColor default visual, switch it to run with PseudoColor or GrayScale. See your X Server documentation for information on how to do this. |
|
Close any local color-intensive X applications (such as bitmap editors and web browsers), to make more colors available for SGImeeting. |
To remove SGImeeting from your computer, use Software Manager (following the relevant instructions in the Software Manager online Help). To open Software Manager from the Toolchest, choose System > Software Manager.
Alternatively, you can remove SGImeeting with shell commands:
