Reconnection to Telnet after network failure

[sreejithp]

Hello,

I am new to python. I have been trying to connect to telnet and feed some data from a server. Its working properly. I used the connectionObj.read_until() method to read the data from the server and made the connection as


self.conn = telnetlib.Telnet(so.telnetHost, so.telnetPort)



thats too fine.

But in case of any network failure it throws an error as follows,

Error (10054, 'Connection reset by peer')

and this error occurred on reading the line

self.conn.read_until(delimiter).

How can I overcome this error or how can I reconnect to the server when recovering the network connection?

More than handling the exception by showing some custom messages, I want to reconnect to the telnet service. Actually the problem occurs in case of network failure where the exception is unavoidable and if system regain the connection then how can I check the connection and reconnect to the telnet to continue feeding the data from the telnet server without restarting the service or without any interaction from me?

Any help would be appreciated.

Thanks & Regards,
Sreejith

Typically we wrap things that may fail in a try block. That way you may handle the error gracefully and continue processing:

try:
    self.conn.read_until(delimiter)
except TelnetError:  # if there is such a thing. The error type is printed in the message
    # Handle the error here
