BSNL modem IPv6 Issue !!


My BSNL modem has following configuration


BoardID:96338W
Software Version:1132_061507-3.08L.BSNL_02.
Bootloader (CFE) Version:1.0.37-8.7
Firmware Version:WA3002G4-0021.01
Hardware Version:WA3002G4 1.0
Model Name:WA3002G4
Wireless Driver Version:3.131.35.6.cpe2.0a.s


IF we enable IPv6 ( which is given in advanced setting )












and reboot the device, the devices wifi goes down. I did not check with Local Ethernet connection , but there seems to be an issue if we enable this option.

When i contacted customer support, they told we do not support IPv6 as of now and, it can not be enabled in the device.

So the question is, why the option is present in the Modem ? It should have been removed.Is testing team is responsible for not raising issue regarding that OR may be they have raised the issue, but internal team did not gave it enough priority ?

You tell me !

Keep breaking , Keep testing !! :-)

How to pass Enthusiast Level of Hurricane Electric IPV6 Certification with Windows XP machine and BSNL connection !

Just now passed the third level of HE-IPv6 free certification ( http://ipv6.he.net/certification/cert-main.php).

This level we need to have one IPv6 capable host, one web server and one domain name to map the IPv6 address of the web server.

This all can be done if we use gogoCLIENT and Freenet6 Tunnel services. Both are free services, only one time registration is required.

The gogoClient can be downloaded from http://www.gogo6.com/gogoware/gogoclient

With this client installed in Windows XP machine, we will get our own IPv6 static ip address, which can be tested  with http://ipv6-test.com/ , if the IP address is properly assigned or not. Also with its Home access version, we get web server also, with account related domain name.

Use this domain name, and web server configuration , you can create one file which is required to be fetched by HE server.

After this there are few basic questions to be answered, and the Certificate ->

IPv6 Certification Tests for individuals, Hurricane Electric IPv6 Certification

Its quite some time i am using IPv6 in my setup. I gave some presentation on IPv6 also.

I was looking for some certification tests for IPv6 and i cam across this:

For individuals : http://ipv6.he.net/certification/cert-main.php

they have many levels, first level some basic questions, passed all.

For second level we need to do some work . Today i got the second level cleared , the "Explorer" certification.


We need to enable IPv6 on client machine.

In my office we have following setup:

                 public IP
Internet----------Router/firewall( NAT)-------------PC1(local ip)

The tunnel has to be created with Public IP, using their another free service

http://www.tunnelbroker.net/

you will give : your public IP , and remote IP ( you can select from the list)

it will create the tunnel. Now got to your client machine , I have Fedora core 16 client machine . In website for all type of OS, you can get the commands: For me following is valid :

Linux-router



modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 230.X.X.X local 192.X.X.X ttl 255
ip link set he-ipv6 up
ip addr add 2001:X:X:X::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr


Make sure that the Local IP is the NAT actual Client IP and not the public IP as given in the example configuration of website.

Now ping

 ping6 ipv6.google.com -> should work fine

 go to http://test-ipv6.com/ and see if they can detect your IPv6 address.

Dual stack Server configuration for IPv4 and IPV6

Ok, so I have finished working on below things , i hope i posted all configurations in my previous posts.

These servers will serve both IPv4 and IPv6 requests.

1) Tftp Server

2) DHCP Server

3) Free Radius Server

4) Telnet Server

5) FTP Server ( Vsftpd)

6) HTTP server

7) Syslog Server

DNS Server is pending and will do it later.

How to enable DHCP Server in Linux Fedora core 16 for both IPv4 and IPv6


How to enable DHCP Server in Linux Fedora core 16 for both IPv4 and IPv6

We need to run two instances of dhcp to serve IPv4 and IPv6 separately, also we should have two config files for this.

1) yum install dhcp-common

    yum install dhcp

2)  cd /etc/dhcpd/


Copy sample files


# cp /usr/share/doc/dhcp*/dhcpd.conf.sample dhcpd.conf


#cp /usr/share/doc/dhcp*/dhcpd6.conf.sample dhcpd6.conf



3) configure the subnets for both IPv4 and IPv6 in config files


# vim /etc/dhcp/dhcpd.conf


subnet 192.16.2.0 netmask 255.255.255.0 {

  range 192.16.2.10 192.16.2.80;
  option routers 192.168.2.1;
  option broadcast-address 192.168.2.255;
  default-lease-time 600;
  max-lease-time 7200;
}



# vim /etc/dhcp/dhcpd6.conf



subnet6 2001:db8:1:0::/64 {

        range6 2001:db8:1:0::10 2001:db8:1:0::80;

        range6 2001:db8:1:0:: temporary;

        prefix6 2001:db8:1:0:: 2001:db8:1:0:: /64;
      
           # Override of the global definitions,
        # works only when a resource (address or prefix) is ass
#       option dhcp6.name-servers 3ffe:501:ffff:101:200:ff:fe00

}


Save both the files


4) Start the servers

  dhcpd -4 -cf /etc/dhcp/dhcpd.conf

  dhcpd -6 -d -cf /etc/dhcp/dhcp6.conf

Got error-> "Can't open lease file /usr/local/var/db/dhcp6.lease"


5) vim /etc/dhcp/dhcpd6.conf'

change log path :

dhcpv6-lease-file-name "/var/lib/dhcpd/dhcpd6.leases";

6) Generate blank file

   touch /var/lob/dhcpd/dhcpd6.leases

7) Kill the servers, if running and start again the servers

   dhcpd -4 -cf /etc/dhcp/dhcpd.conf

  dhcpd -6 -d -cf /etc/dhcp/dhcp6.conf


8) Verify by making any Windows 7 Windows PC as IPv6 Client, it should get the ip address from this Server.

How to enable rsyslog for both IPv4 and IPv6 in Linux fedora core 16

To enable rsyslog please follow these steps:

Syslog Server Fedora Core 16 PC

1) yum install syslog

2) vim /etc/rsyslog.conf

Modify below things

===================
$ModLoad imuxsock # provides support for local system logging (e.g. via logger c
ommand)
$ModLoad imklog   # provides kernel logging support (previously done by rklogd)
#$ModLoad immark  # provides --MARK-- message capability

# Provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514

# Provides TCP syslog reception
$ModLoad imtcp
$InputTCPServerRun 514

# This one is the template to generate the log filename dynamically, depending o
n the client's IP address.

$template FILENAME,"/var/log/%fromhost-ip%/syslog.log"

#
# # Log all messages to the dynamically formed file. Now each clients log (192.1
68.1.2, 192.168.1.3,etc...), will be under a separate directory which is formed
by the template FILENAME.

 *.* ?FILENAME


=======================


3) start Syslog Server


systemctl restart rsyslog.service


Fedora Core 11 as Syslog Client

1) vim /etc/rsyslog.conf


2) Add the ipv6 server ip address (fe80::1e64:66ff:fec7:8221)

#### MODULES ####

$ModLoad imuxsock.so    # provides support for local system lo
 logger command)
$ModLoad imklog.so      # provides kernel logging support (pre
 rklogd)
#$ModLoad immark.so     # provides --MARK-- message capability

# Provides UDP syslog reception
#$ModLoad imudp.so
#$UDPServerRun 514

*.* @[fe80::1e64:66ff:fec7:8221]

3) Start syslog

systemctl restart rsyslog.service


Test Server

Make another interface down in client ( not the one through which the server is connected )

ifconfig eth1 down

ifconfig eth1 up

Server -> go to /var/log -> you should see ip address of client directory

go to that directory-> vim syslog.log -> should give details about the interface up and down.

How to enable HTTP Server for both IPv4 and IPv6 in Fedora core 16 ( Linux )

Errors and Troubleshooting:


1) vim /etc/httpd/conf/httpd.conf

Verify if you have below line

Listen *:80

this will server both ipv4 and ipv6 address.

2)
In fedora core 16 we have bug , if we start http server


root@localhost ~]# /etc/init.d/httpd start
Starting httpd (via systemctl):  Job failed. See system logs and 'systemctl status' for details.
                                                           [FAILED]


root@localhost ~]# apachectl start
/usr/sbin/apachectl: line 102:  2028 Segmentation fault      $HTTPD $OPTIONS -k $ARGV


To remove this error:

just comment below line vim /etc/httpd/conf.d/perl.conf

 #LoadModule perl_module modules/mod_perl.so

3)  after this when i restarted the server some error came , not exactly captured at that time  but similar to

"hostname nor servname provided, or not known"

for this

vim /etc/httpd/conf/httpd.conf

remove # ( or uncomment below line)

ServerName www.example.com:80

4) restart http service

systemctl start httpd.service

or apachectl start


From another browser try to access apache server, give below URL

http://[2001:db8:1:0:1e6f:65ff:fec5:833d]


You should be able to get fedora test page








How to enable free radius server for both IPV4 and IPV6 in Fedora core 16

How to enable free radius server for both IPV4 and IPV6

1) Download free radius tar file from their website (lets assume name as freeradius)

2) tar xvzf freeradius.tar.gz

3) cd freeradius

4) ./configure

5) make

6) make install

7) The radius server will get install in directory raddb

8) vim /usr/local/etc/raddb/radiusd.conf

ADD below lines if not present



listen {
   
        type = auth
        ipaddr = *
        port = 0
}

listen {
        ipaddr = *
        port = 0
        type = acct
}

listen {
        ipv6addr = ::
        port = 0
        type = auth
}

listen {
        ipv6addr = ::
        port = 0
        type = acct
}


save the file


9) radiusd -X

The server should accept request from both Ipv4 and IPv6 clients.

How to enable telnet server for both IPv4 and IPv6 in Fedora core 16!

To enable Telnet Server please follow below steps :

Fedora core 16 Server as telnet server:


1) yum install telnet-server

2) vim /etc/xinetd.d/telnet


service telnet
{
       disable = no
       flags           = REUSE
       socket_type     = stream
       wait            = no
       user            = root
       server          = /usr/sbin/in.telnetd
       log_on_failure  += USERID
        flags = IPv6
}

Change disable to "no" and add "flags=IPv6"


3) systemctl restart xinetd.service


Fedora Core 11 Client

 telnet  ipv6address%interface-name

Telnet clients supports ipv6 but if you do not specify interface-name in the command , "invalid argument" error will be displayed in clients, when you try to telnet.

telnet fe80::1e63:45ff:fec4:8823%eth1

and

telnet ipv4-address

telnet 192.167.23.2

Both command should work fine.
