In situations where the "nc" or "telnet" commands might be considered a security risk, the following Python script can be used:
import time import socket import sys if len(sys.argv) <> 4: print "Usage: %s address port 4-letter-cmd" % sys.argv[0] else: c = socket.socket(socket.AF_INET, socket.SOCK_STREAM) c.connect((sys.argv[1], int(sys.argv[2]))) c.send(sys.argv[3]) time.sleep(0.1) print c.recv(512)
