Pexpect.before out of syncc

Question

I collect some data from users' routers, connecting via SSH, reading from pexpect. before.

Having trouble on only one router, that his Pexpect output is out of sync. I have 16 parameters that need collecting data from the router.

Solution from @user145078:

session.send(cmd)
index = session.expect([cmd, pexpect.TIMEOUT], 1)
session.send('\n')
index = session.expect([whatever you expect])

Worked a little bit, from 16 parameters, 14 are now in sync, and 2 of them aren't.

I don't know why those 2 parameters are still out of sync. Data is gathered in alphabetical order, meaning if I have commands for 'router_speed', 'signal_to_noise_ratio', 'serial', 'device_uptime','attn' they would be gathered in order:

'attn' 'device_uptime' 'router_speed' 'serial' 'SNR'

With the solution I used for this, only 'SNR' and 'attn' parameters are out of sync, with 'SNR'.before outputting last commands output and 'attn'.before outputing welcoming message to router:

Speedport Plus181\r\n \r\n\r\n\r\n\r\nBusyBox v1.15.3 () built-in shell (ash)\r\nEnter 'help' for a list of built-in commands.

Don't know what to do, all those other solutions are a bit complicated to get into my running code.

Sorry for the bad grammar or bad explanation but I need help:D

Answer 1

Well I fixed it, it was a syntax bug/error in the commands for those two parameters.

missing ), unterminated subpattern at position 37

All is fine now.
