theducksI have been suffering a fear of loosing all my data due to it being on magnetic media, so this morning I started backing up the really important stuff to CD-R. Eeeexcellent... non magnetically sensitive media.
Funny day at work today.. came in after being away for 2 days without telling anyone other than my boss.. and there were 6 messages on my voice mail. Silly heads ;> Should have called the main support number.
But the funny thing, was an internal mail envelope with a duck in it! Hehehe QUACK! Twas from![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
dexywexy. Her mum works at UWA, and she stuck it in the internal mail while she was there on Monday. Getting ducks by internal mail is fun. Explaining it to co-workers is also fun.. especially pretending like it's nothing unusual ;)
Lunch at KK's with some people from various parts of work. KK's has new staff.. and they suck. Hmm I hope the old ones were just on holidays or something :/
But my masterpiece today was writing a program I'd been thinking of for a long time.. something to find a machine on our network. Stayed at work till 6PM tonight finishing off first alpha of it. Seems to work nicely, but the code's a bit ugly and I'm doing some things in a very kludgy way. Annnyway.. I'll clean it up tomorrow, but the main thing is that it's about 80% done :) Yay.
It only works with Ciscos running CDP and SNMP on VLAN'ed subnets, but that's ok, cause we got plenty of them. Tomorrow I'll be adding stuff to detect non VLAN'ed switches. Then the heretics should be scared!
First it pings the IP, to get the MAC into the switching fabric of all the switches in the path. Then it queries our core switching router, and asks which VLAN it's on.
Then it queries that VLAN and asks which VLAN port it is assigned to. Then it queries again to find out what physical port that is assigned to, then it queries again to find the CDP neighbour downstream of that port. Then it queries the switch on the downstream port to find out which port the thing is connected to. It keeps on doing this until there are no CDP neighbours on the downstream port, then it returns the port name and description grabbed with SNMP.
Tomorrow, I'll be adding in speed and duplex of the port and some guessing like "this looks like a hub" or "this looks like a non cisco switch" or "the machine is probably connected to this port directly". Eeexcellent. Then I'll release it to some people for beta testing, stick it on sourcefourge, and make a fortune. Well maybe not the last part... depends how I feel. I need a name for it too.
Mumsie making stir fry noodles for dinner. I need to go help :)
QuaCk!
