# This test checks for operation of the MOSH_SERVER_NETWORK_TMOUT variable.
|
|
# It does this by

|
# * setting the variable
|
|
# * killing the client (and its network traffic)
|
|
# * waiting server-side, for the server to die
|
|
# If it is killed, the test is successful.
|
|
# If it survives that long and the server is still around, the test fails.
|
|
# The client waits a bit longer than the server so that status can be collected
|
|
# properly.
