Here’s how to block web sites using Linksys WRT54G router. Through this way we can make a block for every computer that we want or all the computers available and connected to the linksys router.

1. Login to your router by going to the IP address of it in your web browser. By default, it’s usually http://192.160.1.1

2. Click Access Restrictions.

3. In the drop down at the top of the screen, you can select which policy number you want to use.

BLock Sites with Linksys

4. Give the policy a name. I have named it Block Facebook in this example.

5. Click the Edit List of PCs button. It will bring up a window where you can specify which computers/connections to apply this rule to. You can do it by the network card MAC address or the IP address of the computer you wish to block. I prefer to use MAC address, because the IP address may change from day to day. The MAC address is usually listed on the network card. Click Save Settings when you’re done.

6. In the Website Blocking by URL Address, you can type the web address you would like to block. In my example, I have typed http://www.facebook.com

7. Be sure to click Save Settings when you are done.

After post about Setup NIS Server with OpenBSD, now this post its about how to setup NIS Client.

* Enable RPC

/etc/rc.conf:
portmap=YES

* Enable NIS client

root # echo mynisdomain > /etc/defaultdomain

(Other client OSes may do this differently.)

We’ll start ypbind later.

* Enable Amd automounter

/etc/rc.conf:
amd=YES

root # echo “/home amd.home” >> /etc/amd/master

Note that the automounted home is mounted on top of the existing /home.

* Enable lockd for NFS locking (mutt uses it for example)

/etc/rc.conf:
rpc.lockd=YES

* Append NIS maps to passwd and group files

root # vipw # Append the following line
+:*::::::::

root # pwd_mkdb /etc/master.passwd

root # vi /etc/group # Append the following line
+:*::

Might also want to prepend a ‘+’ to existing group entries so that they are overriden by the NIS map entry. For example

+wheel:*:0:root

See passwd(5), group(5) and afterboot(8) for details.

* Install optional shells

Need to add shells needed by master accounts in same locations. For example if master has users with /bin/zsh then client needs a /bin/zsh too.

* Start the daemons

root # portmap
root # ypbind
root # amd -x error,noinfo,nostats -a /tmp_mnt -l syslog /home amd.home
root # rpc.lockd

These will restart on boot.

Non OpenBSD clients are similar but differ in the details, for example, my FreeBSD 5.3 client has an /etc/rc.conf containing these lines:

rpcbind_enable=”YES”
nisdomainname=”mynisdomain”
nis_client_enable=”YES”
amd_enable=”YES”
amd_flags=”-x error,noinfo,nostats -a /.amd_mnt -l syslog /home amd.home”
nfs_client_enable=”YES”
rpc_lockd_enable=”YES”

Master server setup

* Enable RPC

/etc/rc.conf:
portmap=YES

* Enable the NFS server

/etc/rc.conf:
nfs_server=YES
lockd=YES
nfs_flags=”-tun 4″ # 4 simultaneous clients. Crank if needed

/etc/exports:
# change to match your lan addresses and requirements
/home -maproot=0 -network 172.21.0.0 -mask 255.255.0.0

* Enable NIS master server

root # echo “mynisdomain” > /etc/defaultdomain

(Change ‘mynisdomain’ to something suitable)

root # ypinit -m

/etc/rc.conf:
ypserv_flags=
yppasswdd_flags= # Allows password changes from remote machines

* Start the daemons

root # portmap
root # nfsd -tun 4
root # mountd
root # rpc.lockd
root # ypserv
root # ypbind
root # rpc.yppasswdd

These will all be restarted on reboot.

* Create user accounts and populate /home

Install favourite shells (for example zsh, bash). Update /etc/shells, /etc/usermgmt.conf and /etc/skel with preferences and defaults, for example, supply a default password and provide shell startup scripts.

root # useradd -m newuser
…

Add new users to supplementary groups in /etc/group, wheel for example.

* Create an automounter map for client machines

Edit /etc/amd/amd.home to contain these 2 lines:

/defaults type:=nfs;sublink:=${key};opts:=rw,soft,intr,vers=2,proto=udp
* rhost:=mymasterhost;rfs:=/home

Change mymasterhost to hostname of master server. Can also have special per-user settings if needed.

[Note vers=2 is the only option I could get locking over NFS working with a FreeBSD NFS client. OpenBSD's amd complains that these are old style options. What should I be using that's portable?]

* Update the master NIS maps with new changes

root # cd /var/yp; make

Some days I’m trying to install IP-DSLAM device and the Blue-Link Modem. This device serves to connect ADSL internet access which first entered into the IP-DSLAM then continued connections with ADSL connections into the Blue-Link Modem. Well this time I want to write about setting Blue-Link Modem that I use.

• First of all login to Blue-Link modem with the username admin and password admin.
• Then select the Wizard menu, note VPI and VCI. Then click Next



• Then on Connection Type I chose “MER 1483″ in order to enable NAT funsi. Meanwhile, if you want to functioning as a bridge can choose Bridged 1483, and then click next.



• Fill IP WAN with Static IP or obtain if the IP WAN to get DHCP and then the contents of “IP DNS Server” and click Next.



• Then the contents of IP LAN, and if you want to have 2 classes or IP segment 2 Lan, you can activate the “Enable Secondary IP”. And as usual, click Next.



• On the following pages you will see the status of the results of this setting, the next step please click Finish.



• And connections with the Blue-Link Modem is ready for use.

RouterOS password can only be reset by reinstalling the router, or using the reset jumper (or jumper hole) in case the hardware is RouterBOARD.

For RouterBOARDS just close the jumper and boot the board until the configuration is cleared. For some RouterBOARDs there is not a jumper, but a jumper hole – just put a metal object into the hole, and boot the board.
