Expect Usage Examples
Example #1 Expect Usage Example
This example connects to the remote host via SSH, and prints the remote uptime.
<?phpini_set("expect.loguser", "Off");$stream = fopen("expect://ssh root@remotehost uptime", "r");$cases = array ( array (0 => "password:", 1 => PASSWORD));switch (expect_expectl ($stream, $cases)) { case PASSWORD: fwrite ($stream, "password\n"); break; default: die ("Error was occurred while connecting to the remote host!\n");}while ($line = fgets($stream)) { print $line;}fclose ($stream);?>
The following example connects to the remote host, determines whether installed OS is for 32 or 64 bit, then runs update for specific package.
Example #2 Another Expect Usage Example
<?phpini_set("expect.timeout", -1);ini_set("expect.loguser", "Off");$stream = expect_popen("ssh root@remotehost");while (true) { switch (expect_expectl ($stream, array ( array ("password:", PASSWORD), // SSH is asking for password array ("yes/no)?", YESNO), // SSH is asking whether to store the host entry array ("~$ ", SHELL, EXP_EXACT), // We've got the shell! ))) { case PASSWORD: fwrite ($stream, "secret\n"); break; case YESNO: fwrite ($stream, "yes\n"); break; case SHELL: fwrite ($stream, "uname -a\n"); while (true) { switch (expect_expectl ($stream, array ( array ("~$ ", SHELL, EXP_EXACT), // We've got the shell! array ("^Linux.*$", UNAME, EXP_REGEXP), // uname -a output ), $match)) { case UNAME: $uname .= $match[0]; break; case SHELL: // Run update: if (strstr ($uname, "x86_64")) { fwrite ($stream, "rpm -Uhv http://mirrorsite/somepath/some_64bit.rpm\n%22); } else { fwrite ($stream, "rpm -Uhv http://mirrorsite/somepath/some_32bit.rpm\n%22); } fwrite ($stream, "exit\n"); break 2; case EXP_TIMEOUT: case EXP_EOF: break 2; default: die ("Error has occurred!\n"); } } break 2; case EXP_TIMEOUT: case EXP_EOF: break 2; default: die ("Error has occurred!\n"); }}fclose ($stream);?>
