Of coz, Install GCC 3.4 first.

Having a “small” problem with HSRP.

ASCII Network Diagram

[switch-a1]--[router-a1]--[ISP 1 Cloud]--[router-b1]--[switch-b1]--- Active Link
|          |                           |              |
[switch-a2]--[router-a2]--[ISP 1 Cloud]--[router-b1]--[switch-b2]--- Standby Link

I configured HSRP all on devices. My problem is, when a switch-a1 fails, router-a1 fails over to router-a2. but router-b1 will not fail over as the link between router-a1 and router-b1 via ISP 1 is still up.

I tried HSRP tracking, but the best tracking method I found is IP Route Reachability.
Track shows the object is up if the gateway to that network is still in your routing table.

so even configuring “track 100 ip route 10.2.2.2/32 reachability” doesn’t work, as the gateway is added manually as a static route.

Sample Config from Cisco.

To reset the Symantec System Center admin user password

1. On the computer running Symantec System Center, start Windows Explorer.
2. Go to \Program Files\Symantec\Symantec System Center\Tools.
3. In the right pane, double-click the IFORGOT.exe file.
4. In the Primary server field, type the name of the server group’s primary server.
5. In the user field, type admin
6. In the New Password and Confirm New Password fields, type the new password.
7. Click Reset Password.
You may be prompted for a Windows user name and password if you specify a remote server.

Finally, I got both my boxes fixed. So I was happily connecting them together with a SC cable…. yah yah.. It’s only 15cm apart but still it’s a 1Gbps Fibre Channel link 😀

I decided to use dhcp for that link, since I haven’t tried configuring dhcpd before.

After configuring dhcpd on webmin, I tried starting it. The button still shows “Start Server”.

syslog presents:
Nov 9 19:53:24 localhost dhcpd: No subnet declaration for eth0 (10.x.x.x).
Nov 9 19:53:24 localhost dhcpd: Please write a subnet declaration in your dhcpd.conf file for the
Nov 9 19:53:24 localhost dhcpd: network segment to which interface eth0 is attached.
Nov 9 19:53:24 localhost dhcpd: exiting.

wtf, I actually configured for eth3 in the options. So i check /etc/dhcpd.conf, no mention of eth0. Got more pissed after starting the server several times, then I checked /etc/init.d/dhcp..

#Defaults
INTERFACES=”eth0″

So, ok. now I know the reason, changed it.. SAME ERROR !
This time i saw /etc/defaults/dhcp, added INTERFACES=”eth3″

Now it works. Installing Ubuntu on my 2nd box..
