Connection: Settings

Top 


Network Assistant uses connection settings for basic communications between computers. For example, UDP protocol is used for maintaining Users List, Chat, Whiteboard and some notifications. Connection settings are very important for proper work of Network Assistant. There are two available communication modes (both use UDP protocol): IP Multicast and UDP Broadcast.

 

important Important !

ALL computers within your network should use either IP Multicast or UDP Broadcast communication mode in order to communicate with each other.

 

 

RADIO IP Multicast mode

In comparison to UDP Broadcasts, IP Multicast is a bandwidth-conserving technology that greatly improves interoperability in routed environment and allows traffic-friendly group messages. IP Multicast mode is the default and preferred mode since it is better suited for internal corporate broadcasts. It allows you to communicate with users of your own network segment, external network segments and even with remote users over Internet. You should always use IP Multicast unless you have some limitations or problems with it.

 

edit IP Multicast group address

IP Multicast is based on the concept of a group that has its own unique group address. Please note that each Nassi within your network should belong to the same group and use one group address in order to communicate with each other. However, you may find this setting very useful when, for example, you want to split your network into several different Nassi-powered segments - in that case you need to assign a different addresses for each such segment.

 

The valid IP range for this setting is 224.0.1.0 ... 238.255.255.255. Some addresses can be reserved.

 

updown Network scope (IP time-to-live)

This setting defines network scope for outgoing UDP packets. For simple non-segmented networks the value of 1 will be enough.

 

 

 

RADIO UDP Broadcast mode

UDP Broadcast mode can be used in small networks when IP Multicast mode can not be used for some reason.

 

Broadcast addresses

In this list you can specify broadcast addresses that Network Assistant should use to send UDP packets.

 

important Important

For most small non-segmented networks you should keep the default 255.255.255.255 address and do not change the list of broadcast addresses. This list is required for advanced tuning only.

 

For example, imagine that all computers in your network (or subnetwork) have addresses like 10.10.10.x and subnet mask is 255.255.255.0. In this case you should remove the address 255.255.255.255 from the list and add new address - 10.10.10.255. If you have several network segments and want to make Nassi working across them all you should add direct broadcast addresses for all segments.

 

You can also add an exact IP-addresses of a single computers (this is useful, for example, when you want to communicate via Nassi with Internet or RAS-connected user or when a particular LAN-computer is simply invisible by other users for some reason). To temporarily disable a broadcast IP address remove its check mark.

 

 

 

updown UDP port

This setting allows you to specify the port that Nassi should use to send and receive UDP packets in both Multicast and Broadcast modes. It is strongly recommended to keep the default value (50138) for this setting untouched. Please note that each Nassi within your network should use the same port number in order to communicate with each other. However, you may find this setting very useful when, for example, you want to split your network into several different Nassi-powered segments (neighborhoods) - in that case you need to assign a unique port value for each such segment.

 

updown TCP port

TCP port is used in TCP-based communications between remote copies of Nassi: for screenshot/clipboard transfers and file transfers. This setting allows you to specify the special value for this option.

 

 

 

Combobox Binding interface

This list allow you to specify/select the local IP address of your computer. By default, with "Autodetect" option selected, Nassi automatically detects all available network interfaces/IPs and selects the most suitable one as a current local IP address (binding interface). However you can select/enter any other desired valid IP address. This can be useful if Nassi detects its network interface incorrectly.

 

 

 

important Important

- You need to restart Network Assistant in order to apply new connection settings.

- You need to switch to the Administrator mode to be able to change connection settings.
