bssh - ver. 0.3\r\n\r\nBulk SSH (bssh) is a python script written to provide remote command \r\nsubmission to one or more servers\/hosts using ssh protocol. Written to run\r\non Win32 environment, should run on Linux with minor or no modification.\r\n\r\nVERSION HISTORY:\r\n0.1: Simple command execution \r\n0.2: Support to input response to programs running on remote host.\r\n0.3: Added username and password parameters.\r\n \r\nINSTALATION: \r\nDownload and run the following installers:\r\nhttp:\/\/www.python.org\/ftp\/python\/2.7.1\/python-2.7.1.msi\r\nhttp:\/\/bialix.com\/python\/paramiko-1.7.3-ctypes.win32.exe\r\nhttp:\/\/www.serenethinking.com\/bitlift\/tl_files\/pycrypto-2.3.win32-py2.7.msi\r\n\r\nUSAGE: \r\nbssh <options>\r\n\r\nOPTIONS:\r\n-h, --help\r\n Show this help.\r\n-d, --debug\r\n Show debug messages.\r\n-c, --command=<command>\r\n Single command to be executed on remote server.\r\n-f, --commandfile=<command file name>\r\n Name of the file containing all commands that will run on remote \r\n server. (See below for details)\r\n-s, --server=<server name>\r\n Single target server name or IP address.\r\n-l, --serverlist=<server list file name>\r\n Name of the file containing all target servers names or IP address,\r\n one per line.\r\n-o, --output=<file name>\r\n Sends output text to a file.\r\n-u, --username=<user id>\r\n User id to ssh sign-on.\r\n-p, --password=<password>\r\n User password to ssh sign-on.\r\n \r\nCOMMAND FILE:\r\nText file containing one command per line to be executed on the remote \r\nhost\/server. Each command is preceded of a meta command to be interpreted \r\nby bssh script as follows.\r\n\r\nMeta commands:\r\n $C <command>\r\n Executes a command on remote host and catches it's stdout\r\n $R <command>\r\n Run a program and feeds to it's prompts with \"input text\" ($I)\r\n provided right below.\r\n $I <input text>\r\n Text to be provided to programa executed with \"run\" ($R) command.\r\n For consecutive responses, use $I for each program prompt.\r\n # <comment>\r\n The trailing text will not be executed and will be considered as\r\n a comment.\r\n\r\nAdditionaly to meta commands there are some meta data that can be used\r\nin a command line.\r\n\r\nMeta data:\r\n $user$\r\n Replaced by username provided as credential to SSH login.\r\n $pass$\r\n Replaced by password provided as credential to SSH authentication.<\/pre>\n
