Ich habe endlich mein python pexpect-Skript am Laufen, bis auf den wichtigsten Teil, der das Datum aktualisiert! Ich kann in der Box SSH ausführen, aber mein zweiter Befehl wird nicht ordnungsgemäß ausgeführt. Ich habe meinen Kopf gegen die Wand gestoßen, um herauszufinden, warum. Ich habe die Ausgabe des Stichs überprüft und es sollte basierend auf dem, was codiert ist, funktionieren. Ich bin kein Experte, wenn es um Python oder pexpect geht, daher brauche ich ein bisschen Hilfe, um herauszufinden, warum meine Zeit nicht aktualisiert wird.

Mein ursprünglicher Code:

list = ["089"]
sn = 0

ssh_new_conn = 'Are you sure you want to continue connecting'

class ThreadClass(threading.Thread):
def __init__(self, index):
super(ThreadClass, self).__init__()
self.index = index
def run(self):

sn = storelist[self.index]


#easterndate = (currenttime + datetime.timedelta(0, 3600))
#easterndate = easterndate

est = timezone('US/Eastern')
cst = timezone('US/Central')
#currenttime = (datetime.now())
currenttime = cst.localize(datetime.now())
#easterndate = (currenttime + timedelta(0, 3600))
#easterndate = easterndate.strftime("%a %b %d %H:%M:%S %Z %Y")
easterndate = currenttime.astimezone(est).strftime("%a %b %d %H:%M:%S %Z %Y")
command1 = "/usr/bin/ssh %(username)s@%(hostname)s" % locals()
command2 = " sudo date -s\"%(easterndate)s\"" % locals()
command3 = " sudo date -s\"%(currenttime)s\"" % locals()
now = datetime.now()

#central
if sn == "073" or sn == "066" or sn == "016": #or sn == "022":
    p = pexpect.spawn((command1 + command3), timeout=360)


#eastern
else:
    print(command1 + command2)
    p = pexpect.spawn((command1 + command2), timeout=360)


# Handles the 3 possible connection outcomes:
# a) Ssh to the remote host for the first time, triggering 'Are you sure you want to continue connecting'
# b) ask you for password
# c) No password is needed at all, because you already have the key.
i = p.expect([ssh_new_conn,'[pP]assword:',pexpect.EOF])
print ' Initial pexpect command output: ', i
if i == 0:
    # send 'yes'
    p.sendline('yes')
    i = p.expect(['[pP]assword:',pexpect.EOF])
    print 'sent yes. pexpect command output', i
    if i == 0:
        # send the password
        print "logging into box %(sn)s" % locals()
        p.sendline(password)
        print "login successful"
        print "Setting the time..."

elif i == 1:
    # send the password
    print "logging into box %(sn)s" % locals()
    p.sendline(password)
    print "login successful"
    print "Setting the time..."
    p.close()

elif i == 2:
    print "pexpect faced key or connection timeout"
    pass

print p.before

for i in range(len(list)):
  t = ThreadClass(i)
  t.start()

Neuer Code:

class ThreadClass(threading.Thread):
def __init__(self, index):
   super(ThreadClass, self).__init__()
   self.index = index
def run(self):

    try:
        sn = storelist[self.index]
        username = raw_input('username: ')
        password = raw_input('password: ')
        hostname = "[hostname]"
        est = timezone('US/Eastern')
        cst = timezone('US/Central')
        #currenttime = (datetime.now())
        currenttime = cst.localize(datetime.now())
        #easterndate = (currenttime + timedelta(0, 3600))
        #easterndate = easterndate.strftime("%a %b %d %H:%M:%S %Z %Y")
        easterndate = currenttime.astimezone(est).strftime("%a %b %d %H:%M:%S %Z %Y")
        ssh = pxssh.pxssh()

        print(hostname + " " + username + " " + password)
        ssh.login(hostname, username, password)

        if sn == "073" or sn == "066" or sn == "016": #or sn == "022":
            ssh.sendline ('date')       # run a command
            ssh.prompt()                # match the prompt
            print(s.before)           # print everything before the prompt.
            ssh.sendline ('sudo date -s\"%(currenttime)s\"' % locals())  # run a command
            ssh.expect('(?i)password.*:')  # match password prompt for sudo
            ssh.sendline(password)
            ssh.prompt()
            print(s.before)
            ssh.logout()
        else:
            ssh.sendline ('date')       # run a command
            ssh.prompt()                # match the prompt
            print(s.before)           # print everything before the prompt.
            ssh.sendline ('sudo date -s\"%(easterndate)s\"' % locals())  # run a command
            ssh.expect('(?i)password.*:')  # match password prompt for sudo
            ssh.sendline(password)
            ssh.prompt()
            print(s.before)
            ssh.logout()

    except pxssh.ExceptionPxssh as e:
        print(e)


for i in range(len(storelist)):
  t = ThreadClass(i)
  t.start()

Neuer Fehler, den ich erhalte:

Traceback (most recent call last):
  File "./sshtest.py", line 8, in <module>
    s.login (hostname, username, password)
  File "/usr/lib/python2.6/dist-packages/pxssh.py", line 243, in login
    if not self.synch_original_prompt():
  File "/usr/lib/python2.6/dist-packages/pxssh.py", line 134, in synch_original_prompt
    self.read_nonblocking(size=10000,timeout=1) # GAS: Clear out the cache before getting the prompt
  File "/usr/lib/python2.6/dist-packages/pexpect.py", line 824, in read_nonblocking
    raise TIMEOUT ('Timeout exceeded in read_nonblocking().')

LÖSUNG FÜR FEHLER

Ich fand die Lösung für den Fehler, den ich bekam. Aufgrund eines bekannten Fehlers musste ich die folgenden Zeilen zu usr / lib / python.2.6 / dist-packages / pxssh.py hinzufügen:

self.sendline()       #line 134
time.sleep(0.5)       #line 135
self.read_nonblocking(size=10000,timeout=1) # GAS: Clear out the cache before getting the prompt
