Wireless Bridge



HW: WRT54GL CL7C v1.1 FW: DDWRT v23 SP2 (dd-wrt.v23_wrt54g.bin)


I couldn't set up the secondary router (client bridge) using the setup from the picture: I kept losing my connection to the router after disabling DHCP. I tried release and renew and even rebooting my PC, all to no avail. Holding the reset button seemed to be the only recovery.


Instead of using the picture's configuration for my 2nd router, I did only the following in the order listed:


[[ADMINISTRATION > FACTORY DEFAULTS]]

1. Restore Factory Defaults : Yes (only if config was changed after last restore)


[[WIRELESS > BASIC SETUP]]

2. Wireless Mode : Client Bridge (Note: this automatically disables DHCP but comms with router is not disrupted, which is what seems to happen when explicitly disabling DHCP)

3. WIRELESS NETWORK SETTINGS : match primary router setting

4. Click Save settings button


[[WIRELESS > WIRELESS SECURITY]]

5. WIRELESS NETWORK SETTINGS : match primary router setting

6. Click Save settings button


[[WIRELESS > ADVANCED SETTINGS]]

7. Authentication Type : match primary router setting / Shared Key if WEP

8. Click Save settings button


[[SECURITY > FIREWALL]]

9. SPI Firewall : Disable

10. Click Save settings button


[[STATUS > WIRELESS]]

11. Click Site Survey button

12. Find primary router by SSID and click its Join button

คำสั่งที่ใช้ทั่วไปส่วนใหญ่จะใช้ 2 คำสั่ง:

tasklist = คำสั่งใช้ดู process
taskkill = คำสั่งใช้ kill process

ตัวอย่าง
ต้องการ kill process ด้วยชื่อโปรแกรม เช่นต้องการ kill process โปรแกรม notepad.exe ทิ้ง

TASKKILL /F /IM "notepad.exe"

หรือใช้ tasklist ดู process ID เช่น notepad.exe process ID=1234 เมื่อรู้ process ID แล้วสามารถใช้คำสั่ง kill process ได้ดังนี้

TASKKILL /F /PID 1234

*** แนวการนำไปใช้สามารถนำไปประยุกต์ใช้ในการเขียน Scrip เพื่อปิดโปรแกรมต่างๆ ที่ทำงานเสร็จแล้วไม่ยอมปิดตัวเอง ***

TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/F] [/T]

Description:
    This command line tool can be used to end one or more processes.
    Processes can be killed by the process id or image name.

Parameter List:
    /S    system           Specifies the remote system to connect to.

    /U    [domain\]user    Specifies the user context under which
                           the command should execute.

route add <destination ip> mask <subnet> <gateway>

ตัวอย่าง ถ้า add เครื่องเดียว
route add 192.168.2.1 mask 255.255.255.255 192.168.1.1

ถ้า add 24 bit (ทั้ง subnet)
route add 192.168.2.0 mask 255.255.255.0 192.168.1.1

C:\>route add /?

Manipulates network routing tables.

ROUTE [-f] [-p] [command [destination]
                  [MASK netmask]  [gateway] [METRIC metric]  [IF interface]

  -f           Clears the routing tables of all gateway entries.  If this is
               used in conjunction with one of the commands, the tables are
               cleared prior to running the command.
  -p           When used with the ADD command, makes a route persistent across
               boots of the system. By default, routes are not preserved
               when the system is restarted. Ignored for all other commands,
               which always affect the appropriate persistent routes. This
               option is not supported in Windows 95.
  command      One of these:
                 PRINT     Prints  a route
                 ADD       Adds    a route
                 DELETE    Deletes a route
                 CHANGE    Modifies an existing route
  destination  Specifies the host.
  MASK         Specifies that the next parameter is the 'netmask' value.
  netmask      Specifies a subnet mask value for this route entry.
               If not specified, it defaults to 255.255.255.255.
  gateway      Specifies gateway.
  interface    the interface number for the specified route.
  METRIC       specifies the metric, ie. cost for the destination.

All symbolic names used for destination are looked up in the network database
file NETWORKS. The symbolic names for gateway are looked up in the host name
database file HOSTS.

If the command is PRINT or DELETE. Destination or gateway can be a wildcard,
(wildcard is specified as a star '*'), or the gateway argument may be omitted.

If Dest contains a * or ?, it is treated as a shell pattern, and only
matching destination routes are printed. The '*' matches any string,
and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.
Diagnostic Notes:
    Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
    Example> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1 IF 1
             The route addition failed: The specified mask parameter is invalid.
 (Destination & Mask) != Destination.

Examples:

    > route PRINT
    > route ADD 157.0.0.0 MASK 255.0.0.0  157.55.80.1 METRIC 3 IF 2
             destination^      ^mask      ^gateway     metric^    ^
                                                         Interface^
      If IF is not given, it tries to find the best interface for a given
      gateway.
    > route PRINT
    > route PRINT 157*          .... Only prints those matching 157*
    > route CHANGE 157.0.0.0 MASK 255.0.0.0 157.55.80.5 METRIC 2 IF 2

      CHANGE is used to modify gateway and/or metric only.
    > route PRINT
    > route DELETE 157.0.0.0
    > route PRINT

Some times we need to learn own IP address. But not all know how to do it. It is very simple, on the page http://cmyip.ws, you can learn your IP address and some other important information like: domain name, location, country, city, country code, timezone, latitude and longitude from your IP address

But if you wish to get same information from other IP address, you need to use the next key ?ip=OTHER_IP_ADDRESS (http://cmyip.ws?ip=71.141.62.29)

What to learn dialing code, timezone, city, name, area code, zip and etc, you can in the utilies section http://cmyip.ws/?page=utilites

On the http://cmyip.ws/?page=additional you can learn some more information about your inthernet browser, your current IP and port, screen resolution, proxy information.

May be some information will help you to protect youself from bad and died socks or proxy and check all what information other sites can learn about you

##
# deny_hosts
#
# Trust based rule file to define addresses that are implicitly denied.
#
# Format of this file is line-seperated addresses, IP masking is supported.

#
# advanced usage
#
# The trust rules can be made in advanced format with 4 options
# (proto:flow:port:ip);
# 1) protocol: [packet protocol tcp/udp]
# 2) flow in/out: [packet direction, inbound or outbound]
# 3) s/d=port: [packet source or destination port]
# 4) s/d=ip(/xx) [packet source or destination address, masking supported]
#
# Syntax:
# proto:flow:[s/d]=port:[s/d]=ip(/mask)
# s - source , d - destination , flow - packet flow in/out
#
# Examples:
# inbound to destination port 22 from 192.168.2.1
# tcp:in:d=22:s=192.168.2.1
#
# outbound to destination port 23 to destination host 192.168.2.1
# out:d=23:d=192.168.2.1
#
# inbound to destination port 3306 from 192.168.5.0/24
# d=3306:s=192.168.5.0/24
