在cntlm.ini中有例如以下几个重要的配置是可能须要改动的：

• Username - your domain/proxy account name

• Domain - the actual domain name

• Workstation - NetBIOS name of your workstation; Cntlm tries to autodetect it, but you might want to set it explicitly should dialect detection fail (see below)

• Proxy - IP address (or ping-able hostname) of your proxy; if you use several alternative proxies or know of backup ones, use this option multiple times; if one stops working, Cntlm will move on to the next

• Listen - local port number which Cntlm should bind to; the default is OK, but remember you can‘t have more than one application per port; you can use netstat to list used up ports (lines with LISTEN)

# Cntlm Authentication Proxy Configuration
#
# NOTE: all values are parsed literally, do NOT escape spaces,
# do not quote. Use 0600 perms if you use plaintext password.
#

Username	laurence
Domain		abc
Password	123
# NOTE: Use plaintext password only at your own risk
# Use hashes instead. You can use a "cntlm -M" and "cntlm -H"
# command sequence to get the right config for your environment.
# See cntlm man page
# Example secure config shown below.
# PassLM          1AD35398BE6565DDB5C4EF70C0593492
# PassNT          77B9081511704EE852F94227CF48A793
### Only for user ‘testuser‘, domain ‘corp-uk‘
# PassNTLMv2      D5826E9C665C37C80B53397D5C07BBCB

# Specify the netbios hostname cntlm will send to the parent
# proxies. Normally the value is auto-guessed.
#
# Workstation	netbios_hostname

# List of parent proxies to use. More proxies can be defined
# one per line in format <proxy_ip>:<proxy_port>
#
Proxy		192.168.0.1:80

# List addresses you do not want to pass to parent proxies
# * and ?
 wildcards can be used
#
NoProxy		localhost, 127.0.0.*, 10.*, 192.168.*

# Specify the port cntlm will listen on
# You can bind cntlm to specific interface by specifying
# the appropriate IP address also in format <local_ip>:<local_port>
# Cntlm listens on 127.0.0.1:3128 by default
#
Listen		3128

# If you wish to use the SOCKS5 proxy feature as well, uncomment
# the following option. It can be used several times
# to have SOCKS5 on more than one port or on different network
# interfaces (specify explicit source address for that).
#
# WARNING: The service accepts all requests, unless you use
# SOCKS5User and make authentication mandatory. SOCKS5User
# can be used repeatedly for a whole bunch of individual accounts.
#
#SOCKS5Proxy	8010
#SOCKS5User	dave:password

# Use -M first to detect the best NTLM settings for your proxy.
# Default is to use the only secure hash, NTLMv2, but it is not
# as available as the older stuff.
#
# This example is the most universal setup known to man, but it
# uses the weakest hash ever. I won‘t have it‘s usage on my
# conscience. :) Really, try -M first.
