OS X Networking

The following information was compiled before we started using a networking product called ExtremeZ-IP from GroupLogic. Information on Documation's use of ExtremeZ-IP can be found on its own page in this wiki.

The tweaks described in this document apply specifically documation.com internal network.

Specific IP addresses may need to be changed to reflect the current network and server configuration.

OS X Lion [10.7.x] uses a different Windows file browsing module (not Samba) and does not take advantage of an LMHOSTS file. An alternate HOSTS file can be used that may improve network browsing responsiveness. The other tweaks listed are not documentec for OS X Lion at this time (June 1, 2012).

Internet Sharing

Enabling Internet Sharing may help improve network browsing responsiveness.

Create or edit the file nsmb.conf

Location “/private/etc/nsmb.conf” Contents:

  [default]
  minauth = ntlmv2
  notify_off = yes
  domain = documation.com
  nbns = 10.0.0.6

^^^ [the last line is the IP address of the WINS server]

Edit the file smb.conf

Location “/private/etc/smb.conf” find the line: name resolve order = and change the order the values are listed to this order: lmhosts host bcast wins Add the following at the end of the [global] section.

  ; OS X Network Browsing Tweaks
  unix extensions = off
  case sensitive = yes

Add or edit file "sysctl.conf"

Location “/private/etc/sysctl.conf” find the lines below and change the values to the values shown here:

  net.inet.tcp.delayed_ack=1 <-- Possible values are 0, 1, 2, 3 - 3 is the default value.

Create or edit the files "hosts" and "lmhosts"

Location “/private/etc/hosts” and “/private/etc/lmhosts” Contents “/private/etc/hosts”:

  ##
  # Host Database
  #
  # localhost is used to configure the loopback interface
  # when the system is booting. Do not change this entry.
  ##
  127.0.0.1 localhost
  255.255.255.255 broadcasthost
  ::1 localhost
  fe80::1%lo0 localhost
  10.0.0.4 operations
  10.0.0.6 docudc
  10.0.0.7 docuarchive

^^^ [the lines with specific IP addresses are specific servernames]

Contents “/private/etc/lmhosts”:

  10.0.0.2 ftp
  10.0.0.3 administration
  10.0.0.4 operations
  10.0.0.6 docudc
  10.0.0.7 docuarchive
  10.0.0.12 documaster

^^^ [lmhosts simply lists the IP followed by the servername]

Alternate "hosts" configuration for OS X Lion

Location “/private/etc/hosts” Contents “/private/etc/hosts”:
