Error Spawning Telnet Tasks

A wait should not be executed. It is returning immediately and the process still stays in the process chart. To match a regular expression pass '-re' as a parameter in front of the pattern you want to match as a regexp. Please send you questions that are not answered here to [email protected] What systems does Expect run on?

If the third integer was -1, the fourth integer is the value of errno set by the operating system. It is possible that * the connection was killed during login (telnetInTask), * failed login (telnetd) * terminated by shell (shell task) */ /* For STATIC sessions, we need to clean/sanitize This allows to perform some aliveness testing and still expect for patterns. $exp->restart_timeout_upon_receive(1); $exp->expect($timeout, [ timeout => \&report_timeout ], [ qr/pattern/ => \&handle_pattern], ); Now the timeout isn't triggered if the TIA, Aaron -------------------------- Tcl: 8.5.5 Expect: 5.43 Windows: XP and Server 2003 telnet: MS Windows default (5.1.2600.3587 and 5.2.3790.4528, respectively) Line in question: set localTelnetPid [exp_spawn $TELNET_EXE $targetIp $targetPort] For any

The flag itself is optional as it is only useful when using the #! The * argument is equal to the TELNETD_TASKFLAG setting. When a process object is created (not a filehandle initialized with exp_init) the log_stdout setting will match the value of $Expect::Log_Stdout variable, normally 1. exp_send_error is an alias for send_error.

The -nocase flag causes uppercase characters of the output to compare as if they were lowercase characters. This will be determined by the telnetd if parserControl == 0 */ if ((pSlot->loggedIn == TRUE) && (pSlotDelete == TRUE)) free (pSlot); else pSlot->loggedIn = FALSE; } semGive (telnetdMutexSem); } /******************************************************************************* Why would you want to have objects listening to STDOUT (for example)? more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed

Returns current setting if called without parameters. If the last expect() call didn't match anything, exp_after() will return undef(). $object->exp_match() or $object->match() returns the string matched by the last expect() call, undef if no string was matched. $object->exp_match_number() current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list. In this one case, the usual Tcl substitutions will occur despite the braces.

I want to use Expect to automate [anything with a buzzword]... The arguments -raw or cooked put the terminal into cooked mode. This may be useful when the user needs to see feedback from partially typed patterns. Please note that I do strongly object against using Expect to automate ssh login, as there are better way to do that (see ssh-keygen).

If characters are then entered such that there can no longer possibly be a match, only the part of the string will be sent to the process that cannot possibly begin However, because expect is not line oriented, these characters match the beginning and end of the data (as opposed to lines) currently in the expect matching buffer. (Also, see the note What's happening is you are closing the handle before passwd exits. Expect->spawn($command, @parameters) or $object->spawn($command, @parameters) or Expect->new($command, @parameters) Forks and execs $command.

For a generic way to interconnect processes, take a look at IPC::Run. asked 6 months ago viewed 85 times active 6 months ago Related 3Telnet Automation with Expect: Slow authentication?0Expect loses connection after telnet and does not send any subsequent “expect send” commands1send This means your system has a mechanism for gaining the controlling tty that Expect doesn't know about. changed task priority and ids to be global variables so they can be accessed from outside this module. 01d,04apr87,dnw de-linted. 01c,27mar87,dnw documentation fixed bug causing control sequences from remote to be

Note that in the text of this man page, "Expect" with an uppercase "E" refers to the Expect program while "expect" with a lower-case "e" refers to the expect command within The St. The good thing is, switch was serving to portion of a cluster with redundant paths which we now know work beautifully. Declaring expect_background with no pattern removes the given spawn id from the ability to match patterns in the background.

While background processing is blocked, it is possible to do a (foreground) expect on the same spawn id. The functions telnetInTask() and telnetdExit() were changed. exp_continue The command exp_continue allows expect itself to continue executing rather than returning as it normally would. (See expect for more information.) exp_internal [-f file] value causes further commands to send

In addition, the user can take control and interact directly when desired, afterward returning control to the script.

With &, Expect does not have a chance to read the terminal's parameters since the terminal is already disconnected by the time Expect receives control. Upgrade to IRIX 6.1. Of course, any process may be substituted for login.

If "foo" is entered, the user sees "bar". For example, the following prints out the name of the script and the first three arguments: send_user "$argv0 [lrange $argv 0 2]\n" COMMANDS Expect uses Tcl (Tool Command Language). errno:%#x\n", errno, 0, 0, 0, 0, 0); return ERROR; } remoteInitFlag = TRUE; /* Disable further device creation. */ } telnetdTaskFlag = staticFlag; /* Create input/output tasks early? */ telnetdMaxClients = navigate here Some pty implementations may be confused by multiple readers and writers, even momentarily.

I encourage you to read and try out the examples in the example directory of the Expect distribution. This provides a way of changing the I/O source while the command is in execution. Unable to spawn tasks. With no arguments, the current version of Expect is returned.

If "p" is pressed, several returns are sent to the process, perhaps to poke it in some way, and "i" lets the user interact with the process, effectively stealing away control When the connection to the spawned process is closed, so is the Tcl file identifier. The following script reads a password, and then runs a program every hour that demands a password each time it is run. Provided as is.

See $object->exp_internal(). $Expect::IgnoreEintr Defaults to 0. Multiple commands may be executed with a single -c by separating them with semicolons. For example, "set send_slow {10 .001}" would force "send -s" to send strings with 1 millisecond in between each 10 characters sent. While such situations are conceivable, in practice I have never encountered a situation in which the final output of a truly interactive program would

The server uses this routine to clean * up the (partial) task list if an error occurs during multiple task enabled * startup. * * RETURNS: N/A * * NOMANUAL */ Additional elements may appear at the end of the return value from wait. signals is either a single signal or a list of signals. Thus, you must set them explicitly - to what type is usually irrelevant.

This is fixing SPR #1427. By default, reading is performed in cooked mode. share|improve this answer answered Apr 13 at 0:56 f d 112 close also not working and this behaviour is common for windows and Linux systems. –Dinesh Apr 13 at exp_version returns an error if the major numbers match, but the script minor number is greater than that of the running Expect.

is still alive, but you can act upon patterns in the output. $object->notransfer(1 | 0) Do not truncate the content of the accumulator after a match. It behaves just like Expect and Tk's wish.
