This adds methods for login, logout, and expecting the shell prompt. It does various tricky things to handle many situations in the SSH login process. For example, if the session is your first login, then pxssh automatically accepts the remote certificate; or if you have public key authentication setup then pxssh won't wait for the password prompt. pxssh uses the shell prompt to synchronize output from the remote host. In order to make this more robust it sets the shell prompt to something more unique than just $ or #. This should work on most Borne/Bash or Csh style shells. Example that runs a few commands on a remote server and prints the result:: import pxssh import getpass try: s = pxssh.pxssh() hostname = raw_input('hostname: ') username = raw_input('username: ') password = getpass.getpass('password: ') s.login (hostname, username, password) s.sendline ('uptime') # run a command s.prompt() # match the prompt print s.before # print everything before the prompt. s.sendline ('ls -l') s.prompt() print s.before s.sendline ('df') s.prompt() print s.before s.logout() except pxssh.ExceptionPxssh, e: print "pxssh failed on login." print str(e) Note that if you have ssh-agent running while doing development with pxssh then this can lead to a lot of confusion. Many X display managers (xdm, gdm, kdm, etc.) will automatically start a GUI agent. You may see a GUI dialog box popup asking for a password during development. You should turn off any key agents during testing. The 'force_password' attribute will turn off public key authentication. This will only work if the remote SSH server is configured to allow password logins. Example of using 'force_password' attribute:: s = pxssh.pxssh() s.force_password = True hostname = raw_input('hostname: ') username = raw_input('username: ') password = getpass.getpass('password: ') s.login (hostname, username, password) iiÐcCsƒtj|dd|d|d|d|d|d|ƒd|_d|_|j|_d |_d |_d |_t |_ t |_ dS( Nttimeouttmaxreadtsearchwindowsizetlogfiletcwdtenvss\[PEXPECT\][\$\#] sPS1='[PEXPECT]\$ 'sset prompt='[PEXPECT]\$ 's5-o'RSAAuthentication=no' -o 'PubkeyAuthentication=no'( tspawnt__init__tNonetnamet UNIQUE_PROMPTtPROMPTt PROMPT_SET_SHtPROMPT_SET_CSHtSSH_OPTStFalsetforce_passwordtTruetauto_prompt_reset(tselfRRRR R R ((s)/usr/lib/python2.7/dist-packages/pxssh.pyR Is4      c Cst|ƒt|ƒ}}||krB||}}||}}nt|dƒ}xÂtd|dƒD]­}||gdg|}}x‰td|dƒD]t}||d||dd} } ||d} ||d||dkrù| d} nt| | | ƒ||s
