Environment variables used by FSP Clients programs

setenv VARIABLE value | export VARIABLE=value

The following variables are used for access FSP servers:

FSP_HOST

The name or internet number of the machine with the FSP server. Required.

FSP_PORT

The port number of the UDP socket used by the FSP server. Required.

FSP_LOCALIP

Local Address of UDP socket used by FSP client utilities. This IP address must be one of your local IP addresses. If not used, TCP protocol stack sets the default. This variable is mainly used for multi-homed hosts.

FSP_LOCALPORT

The port number of the UDP socket used by FSP client utilities. The only reason to define this variable is to ensure mutual exclusion of client commands when none of the udp packet multiplexing mechanisms are enabled during compile time. You may pick any number not currently used for other purposes.

FSP_PASSWORD

Access password for FSP server. Directories on FSP server can be password protected. FSP server can change your access level if you have provided a correct password. There are 2 access levels: public and owner.

FSP_BUF_SIZE

Prefered size of server reply. Default is 1024 which is also maximum allowed value by all servers. Some servers can accept larger packets and you will get some extra speed with them. You can lower that value if you want to get smaller packets from server.

FSP_DIR

The current working directory of the client in the FSP server. The server's root is /.

FSP_TRACE

If this variable is set to any value, program will display the number of kilo-byte blocks transferred as transfer progresses. Also shown will be a measure of characters per second so that network speed has an indicator. This variable has no effect when the standard output is a terminal.

FSP_TIMEOUT

If this variable is set, it contains the timeout value in seconds. The default value is 360. No function if program was compiled without timeout code.

FSP_DELAY

Minimum wait time before resending packet in milliseconds. This should be set close to expected round trip time.

FSP_MAXDELAY

Maximum wait time before resending packet in milliseconds.

FSP_LOCAL_DIR

Where to look for local files. Default is current directory.
