Cisco SMARTnet and Hardware Replacement

Actually this is an old case in which the Cisco 2800 router that is suddenly broken at the office and all the efforts that we know have been carried out but the router still can not walk properly.

Local checks be done and recommendations can be given is to resend to the nearest dealer for replacement of the goods with new goods. 100% new.

How can this be done?
SMARTnet is the answer, quote from cisco site:

“SMARTnet Gives your IT staff direct, anytime access to Cisco engineers, the Technical Assistance Center (TAC), and an extensive range of online resources. You receive fast, expert technical support, flexible hardware coverage, and smart, personalized capabilities to help you resolve critical network issues. ”

This was indeed true, in the case of faulty hardware router we replaced our router with a new router. Here’s the process sequence:

1. Contact email address
2. Provide the following information in your email:
– No SMARTnet contracts
– Types of router
– Problems occurred
3. Our email reply within 6 hours by a TAC angineer which is dedicated specifically to the problems that we ask.
4. Case is opened and all the history will note there a solution.simply note the case number provided.
5. At this stage all the help of Cisco’s support will be provided either through the guidelines that we must type the command (if the instrument is still able to live up to the remote support). If the machine can live and work well then the case is closed.

In the case of the death total tool then some questions will be posed, the results of this question becomes a reference for the provision of new hardware with the RMA code.

Address details of contact persons associated with this router cisco will be asked by the parties, then a replacement item will be shipped within 1-2 days and will be able to accept. After this replacement tool and can work to replace the damaged device then our task then is to send us the damaged goods to a courier who had been appointed by cisco.

The process can be monitored simply by contacting the logistics or the Asset Recovery department to include the RMA code provided by Cisco. Filling the form will be asked to fill customer satisfaction by the Cisco after all this process is completed properly. In the case that we experienced the time it takes to get the tools and the resolution of all cases only takes 5 days. Our response to this SMARTnet service is exceptional and very professional.

Lessons from this case is if possible to get service Cisco SMARTnet on any device you have. Investments at cost of purchase and this warranty will provide added value and confidence plus for us consumers.

Info: not all resellers Cisco SMARTnet support this, make sure you ask them to make sure you get the best service.

Sender address rejected: Domain not found

I have an order for reinstall email server. I accept the job and finish it in one day ( I use FreeBSD 8.2 release for OS and Postfix for MTA but the longest session during reinstall is backup and migrating mailbox).

Everything seem ok until mail server deployed, local delivery work well except sending to outside. Any email to other email server rejected with ‘domain not found’ message.

I’ve change /etc/resolv.conf to use opendns and google public ip but still not work, the error message still appear and make me little confuse.

After look around finally I got the solution. Its about postfix local resolv.conf file. Postfix has its own resolv.conf file located in /var/spool/postfix/etc.

mail# ls
hosts           localtime       resolv.conf     services

Yes, that resolv.conf file is still holding the value of local dns server I use during installation process.

Change the ip to isp dns server clear my problem and everything seem fine.

Time to set spf record and dkim.

See you.

Quick Setting Bind on FreeBSD 8.1

I’m big fan of djbdns and I already write some post about djbdns and dnscache in the past.

Today, my friend ask me to install or configure bind for his FreeBSD that run 8.1 version. I ask him to follow FreeBSD manual but he said he already follow the guide but still face error.

I agree to help him set quick dns server using bind on his FreeBSD box. I think I have to test it first before give another suggestion and maybe I’ll need it in the future.

Lets get start!

Target : domain will be resolved to

1. Enable bind on start up by add this line in /etc/rc.conf


2. Change a few things on /etc/namedb/named.conf

– Listen to ip

//      listen-on       {; };
listen-on       {; };

– Set forwarders to ip address of router / isp dns

forwarders {;

– Add zone for

zone “”{
type master;
file “/etc/namedb/master/”;

3. Add zone file content (for

ee /etc/namedb/master/

add fill this lines:

$TTL 3600        ; 1 hour default TTL    IN      SOA (
2006051501      ; Serial
10800           ; Refresh
3600            ; Retry
604800          ; Expire
300             ; Negative Response TTL

; DNS Servers
IN      NS
IN      NS

; MX Records
IN      MX 10
IN      MX 20

IN      A

; Machine Names
localhost       IN      A
ns1             IN      A
ns2             IN      A
mx              IN      A
mail            IN      A
www             IN      A
@               IN      A

save the file.

4. Add the address to /etc/resolv.conf

echo ‘nameserver’ >> /etc/resolv.conf

5. Restart dns server

# /etc/rc.d/named restart

Stopping named.
Waiting for PIDS: 2130.
Starting named.

6. Testing resolver

# dig
