@Benjamin: Thanks for bugreport. According to my research it is enough to just add self.sendline() can you confirm it too? I would prefer not to add additional delays if it is not necessary. @Alan: pexpect-u -> it requires python3 which will be in rhel7 only partially and fence-agents were not tested with it at all package renaming -> it was obtained from fedora and no-one complained, otherwise it will be fixed; this way we have to wait for rhel8 |
Description of problem: cannot use pxssh.py which is part of pexpect, always running into timeout: Version-Release number of selected component (if applicable): pexpect-2.3-6.el6.noarch How reproducible: echo <<EOF > ssh.py import pxssh s = pxssh.pxssh() if not s.login ('localhost', 'myuser', 'mypass'): print "SSH session failed on login." print str(s) else: print "SSH session login successful" s.sendline ('ls -l') s.prompt() # match the prompt print s.before # print everything before the prompt. s.logout() EOF Steps to Reproduce: 1. python ssh.py 2. see error msg Actual results: Traceback (most recent call last): File "ssh.py", line 3, in <module> if not s.login ('localhost', 'myuser', 'mypassword'): File "/usr/lib/python2.6/site-packages/pxssh.py", line 243, in login if not self.synch_original_prompt(): File "/usr/lib/python2.6/site-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/site-packages/pexpect.py", line 815, in read_nonblocking r,w,e = self.__select([self.child_fd], [], [], timeout) File "/usr/lib/python2.6/site-packages/pexpect.py", line 1549, in __select return select.select (iwtd, owtd, ewtd, timeout) Expected results: Output of ssh command "ls -l" Additional info: Fix: 132a133,134 > self.sendline() > time.sleep(0.5) add this before line 134, and it works as expected. This should also affect rhel5 pexpect package, but not verified.
