I sarched the existing threads but didnt find an answer to this.
I am writing simple script which uses telentlib to open a session with a unix machine and run "tail -f logfile.txt" on one of the logfiles.
import telnetlib
HOST = "192.X.X.X" user = "myname" password = "mypass"
tn = telnetlib.Telnet(HOST)
tn.read_until("login: ") tn.write(user + "\n") if password: tn.read_until("Password: ") tn.write(password + "\n")
tn.write("tail -f /tmp/logfile.txt\n")
# what do i write here ? #
tn.write("exit\n")
Nitin,
You can not have two writes together. Reads and writes should alternate.
To get the log file this is what you should do:
# Modified my working version for your purpose. # Hope there are not errors!
def SaveLog(user, password):
telnet_resp = []
tn = telnetlib.Telnet(host) tn.read_until("login: ")
tn.write(user + "\n")
if password:
telnet_resp.append( tn.read_until("Password: ") )
tn.write(password + "\n")
tn.read_until("$ ") tn.write("tail -f /tmp/logfile.txt\n") telnet_resp.append(tn.read_until("$ ")) tn.write("exit\n")
telnet_resp.append(tn.read_all() )
tn.close()
telnet_out = open(OUTPUT, 'a') telnet_out.write('\n'.join(telnet_resp)) telnet_out.close()
Alternatively, if your box has FTP access, you can FTP the log file to a CStringIO file and operate on it.
