The following options name the port numbers and passwords that TotalView uses to connect with tvdsvr.
-callback hostname:port
(Autolaunch feature only) Immediately establishes a connection with a TotalView process running on hostname and listening on port, where hostname is either a host name or TCP/IP address. If tvdsvr cannot connect with TotalView, it exits.
If you use the -port, -search_port, or -server options with this option, tvdsvr ignores them.
-callback_host hostname
Names the host upon which the callback is made. The hostname argument indicates the machine upon which TotalView is running. This option is most often used with a bulk launch.
-callback_ports port-list
Names the ports on the host machines that are used for callbacks. The port-list argument contains a comma-separated list of the host names and TCP/IP port numbers (hostname:port,hostname:port...) on which TotalView is listening for connections from tvdsvr. This option is most often used with a bulk launch.

-debug_file console_outputfile
Redirects TotalView Debugger Server console output to a file named console_outputfile.
If console_outputfile is the string UNIQUE, the filename tv_dump.hostname.pid is used. If console_outputfile contains the string '$$' (note the escaping single quotes), hostname.pid is substituted. UNIQUE and '$$' are useful for separating the console output when running multiple tvdsvr processes.
Default: All console output is written to stderr.
-nodes_allowed num
Explicitly tells tvdsvr how many nodes the server supports and how many licenses it needs. This is only used for the Cray XT3.
-port number
Sets the TCP/IP port number on which tvdsvr should communicate with TotalView. If this port is busy, tvdsvr does not select an alternate port number (that is, it won’t communicate with anything) unless you also specify -search_port.
Default: 4142
Searches for an available TCP/IP port number, beginning with the default port (4142) or the port set with the -port option and continuing until one is found. When the port number is set, tvdsvr displays the chosen port number with the following message:
port = number
Be sure that you remember this port number, since you will need it when you are connecting to this server from TotalView.
-serial device[:options]
Waits for a serial line connection from TotalView. For device, specifies the device name of a serial line, such as /dev/com1. The only option you can specify is the baud rate, which defaults to 38400. For more information on debugging over a serial line, see “Debugging Over a Serial Line”.
Listens for and accepts network connections on port 4142 (default).
Using -server can be a security problem. Consequently, you must explicitly enable this feature by placing an empty file named tvdsvr.conf in your /etc directory. This file must be owned by user ID 0 (root). When tvdsvr encounters this option, it checks if this file exists. This file’s contents are ignored.
You can use a different port by using one of the following options: -search_port or -port. To stop tvdsvr from listening and accepting network connections, you must terminate it by pressing Ctrl+C in the terminal window from which it was started or by using the kill command.
-set_pw hexnumhigh:hexnumlow
Sets the password to the 64-bit number specified by the hexnumhigh and hexnumlow 32-bit numbers. When a connection is established between tvdsvr and TotalView, the 64-bit password passed by TotalView must match this password set with this option. tvdsvr displays the selected number in the following message:
pw = hexnumhigh:hexnumlow
We recommend using this option to avoid connections by other users.
If necessary, you can disable password checking by specifying the “-set_pw 0:0” option with the tvdsvr command. Disabling password checking is dangerous; it allows anyone to connect to your server and start programs, including shell commands, using your UID. Therefore, we do not recommend disabling password checking.
-set_pws password-list
Sets 64-bit passwords. TotalView must supply these passwords when tvdsvr establishes the connection with it. The argument to this command is a comma-separated list of passwords that TotalView automatically generates. This option is most often used with a bulk launch.

-verbosity level
Sets the verbosity level of TotalView Debugger Server-generated messages to level, which may be one of silent, error, warning, or info.
Default: info
-working_directory directory
Makes directory the directory to which TotalView connects.
Note that the command assumes that the host machine and the target machine mount identical file systems. That is, the path name of the directory to which TotalView is connected must be identical on both the host and target machines.
After performing this operation, the TotalView Debugger Server is started.
