Disabling Autolaunch Changing the Remote Shell Command Some environments require you to create your own autolaunching command. You might do this, for example, if your remote shell command doesn’t provide the security that your site requires. If you create your own autolaunching command, you must use the tvdsvr – callback and –set_pw command-line options. If you’re not sure whether rsh (or remsh on HP computers) works at your site, try typing “rsh hostname” (or “remsh hostname”) from an xterm window, where hostname is the name of the host on which you want to invoke the remote process. If the process doesn’t just run and instead this command prompts you for a password, you must add the host name of the host computer to your .rhosts file on the target computer. For example, you can use the following combination of the echo and telnet commands: echo %D %L %P %V; telnet %R After telnet establishes a connection to the remote host, you can use the cd and tvdsvr commands directly, using the values of %D, %L, %P, and %V that were displayed by the echo command; for example: cd directory tvdsvr –callback hostname:portnumber –set_pw password If your computer doesn’t have a command for invoking a remote process, TotalView can’t autolaunch the tvdsvr and you must disable both single server and bulk server launches. For information on the rsh and remsh commands, see the manual page supplied with your operating system. Changing Arguments You can also change the command-line arguments passed to rsh (or whatever command you use to invoke the remote process). For example, if the host computer doesn’t mount the same file systems as your target computer, tvdsvr might need to use a different path to access the executable being debugged. If this is the case, you can change %D to the directory used on the target computer. If the remote executable reads from standard input, you cannot use the –n option with your remote shell command because the remote executable receives an EOF immediately on standard input. If you omit the –n command-line option, the remote executable reads standard input from the xterm in which you started TotalView. This means that you should invoke tvdsvr from another xterm window if your remote program reads from standard input. The following is an example: %C %R "xterm –display hostname:0 –e tvdsvr \ –callback %L -working_directory %D –set_pw %P \ –verbosity %V" 92 Chapter 5: Setting Up Remote Debugging Sessions
Figure 78: Launching tvdsvr Disabling Autolaunch Each time TotalView launches tvdsvr, a new xterm appears on your screen to handle standard input and output for the remote program. Autolaunching Sequence This section describes the sequence of actions involved in autolaunching. You can skip this section if you aren’t having any problems or if you aren’t curious. 1 With the File > New Program or dload commands, you specify the host name of the computer on which you want to debug a remote process, as described in “Setting Up and Starting the TotalView Server” on page 81. 2 TotalView begins listening for incoming connections. 3 TotalView launches the tvdsvr process with the server launch command. (See “Using the Single-Process Server Launch Command” on page 87 for more information.) 4 The tvdsvr process starts on the remote computer. 5 The tvdsvr process establishes a connection with TotalView. The following figure summarizes these actions if your program is launching one server. The numbers within this figure refer to the numbers in the preceding procedure.
