Models Telnet sessions with a specific user behaviour. The server app should be TCPGenericSrvApp. Compatible with both IPv4 and IPv6.
NOTE: This module emulates a very specific user behaviour, and as such, it should be viewed as an example rather than a generic Telnet model. If you want to model realistic Telnet traffic, you are encouraged to gather statistics from packet traces on a real network, and write your model accordingly.
The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.
Name | Type | Description |
---|---|---|
address | string | may be left empty ("") |
port | numeric const | port number to listen on |
connectAddress | string | server address (may be symbolic) |
connectPort | numeric const | port number to connect to |
startTime | numeric | time first session begins |
numCommands | numeric | user types this many commands in a session |
commandLength | numeric | commands are this many characters (plus Enter) |
keyPressDelay | numeric | delay between keypresses |
commandOutputLength | numeric | commands produce this much output (bytes) |
thinkTime | numeric | user waits this much before starting to type new command |
idleInterval | numeric | time gap between sessions |
reconnectInterval | numeric | if connection breaks, user waits this much before trying to reconnect |
