28-March-2002 : WWW Site

Things are finally running very smoothly. The WWW site and internet connection have not missed a beat in the last week or so. The internet link is still requiring periodic restarts, but we hope to have that fixed quickly. We are just waiting on new firewall software before changing the configuration of the network. The change from public to private addresses in the DMZ has been quite successful. This will allow us to implement a multi-homed internet link at some point in the future.

20-March-2002 : ADSL and Server Failure

ADSL is now working correctly. I am restarting the modem every few hours automatically to ward off issues that I have been seeing with the modem.

Our main server failed on Saturday causing an outage of several hours. Added to this were some routing issues to do with address translation and the Alcatel Speedtouch Pro ADSL modem. Specifically pinholing does not seem to work well with this modem, and settings seem to be lost on reboot.

8-March-2002 : ADSL

Once again ADSL should be working well. I have powered down the DIALUP connection, and I am running on ADSL only at the moment. I needed to restart the ADSL modem again this evening due to packet losses. I have not yet worked out why - Is it Telstra or Me? Or AlwaysOnline?

6-March-2002 : ADSL : Spoke too soon

OK... Spoke too soon... I am having problems with my connection. An example is

Note the packet losses... This is a killer to TCP/IP. And worse is that

6-March-2002 : ADSL

ADSL should be running properly now. I would not be surprised if there were a few problems with the switchover. Moving things over has been a bit stressful, and required some changes to the way that we do things. With luck things should run smoothly now.

2-March-2002 : ADSL

ADSL is now up and running. Things may not be as reliable as we switch over, so sorry for that. Things should be back to normal shortly >
