Well what I am doing is connecting to a telnet session sending some
commands, exiting and returning some data.
What I would to do is send the commands and return the data without exiting
the session.
I would like to keep the same session and just send commands and return
data.
#!/usr/bin/env python
import telnetlib
class hlr_com():
#get host and command
def __init__(self):
"""init host and command """
self.user_name = '********'
self.password = '**********'
self.host = '172.20.50.176'
self.command = ''
#edit top of return
def fix_return(self,hia_return):
"""
edit the top of data returned form the hia
"""
try:
data = str(hia_return).strip('\r')
return data
except Exception,error:
logs("error",str(err),'null')
#set host ip address
def set_host(self,host):
""" set host ipaddress"""
self.host = host
#send command to hia and end session
def hlr_telnet(self,command):
"""
connect to host and execute command and
exit
"""
try:
hlr_tel = telnetlib.Telnet(self.host)
hlr_tel.read_until('login:')
hlr_tel.write(self.user_name+"\r")
hlr_tel.read_until('Password:')
hlr_tel.write(self.password+"\r")
#execute command
hlr_tel.read_until('maint@atcaHLRds0 /public/users/maint>')
hlr_tel.write(command+'\r')
#end session
data = hlr_tel.read_until('maint@atcaHLRds0
/public/users/maint>')
hlr_tel.write('exit'+'\r')
data2 = self.fix_return(data)
#return data
return data2
except Exception,error:
logs("error",str(err),'null')
def logs(self,log_type,log_data,ip_address):
"""
Log for errors
"""
try:
conn =
psycopg2.connect(database="hlr_proxy",user="postgres",host="localhost",
password="bb_server_1",port="5432") #connect to database
create_date = str(datetime.datetime.now())
cur = conn.cursor() # create cursor
cur.execute("insert into
hlr_logs(create_date,log_type,log_data,ip_address)values(%s,%s,%s,%s)",
(create_date,log_type,log_data,ip_address))
conn.commit()
cur.close()
conn.close()
finally:
try:
log_file = open(r"text_log.txt","a")
log_file.write(create_date+","+log_type+","+log_data+","+str(ip_address)+'\r
'+'\n')
log_file.close()
except Exception,error:
pass

Isn't this the same question you asked back in June?
We tried to answer your question then, did you see our responses, and were
they useful?
At the time, you were complaining that the telnet session was too slow, but
you didn't tell us what you were actually doing. David Heiserca took a guess
as to what you were doing, and suggested what you should do again. Did you
see his response, and was it helpful?
You should show us the code you are using.
