Wish me luck....


Well after much trouble with NT4 and windows boxes in general not to mention having gone through 4 MSit ppl my company has turned over the Georgia operations network to me and is providing several "older" machines to make a server cluster out of it... With Linux of course.
Since last week (aug 6) we have had to reboot 4 servers in 4 states to keep them talking every day. (win NT4). It all started when someone canceled some phone numbers (polling modems, Modems you believe that and all 4 plants have dsl).

The networks are trash with Win OSs from barely 98 to 2000 server as workstations. half the machines are static the others dhcp and more crashes than at Talladega on race day. Every machine over xp home has IPC set and no one knew how to share their files. Every machine in the plant has to be on because the company files are scattered around ALL the computers. Machines with names and user accounts with ppl way gome months ago.

So far I have rebuilt the network removeing the 10x hub and installing a 10/100 switch. Also between the adsl modem and the inet -- a firewall.
Cleaned the spider nest they had up and up graded they old modems for the server to 56k. (when they poll at least our is the fastest).
Next comes a samba server to host both the slaes and production files under one location. I will also be setting up a name server (local) also on this same box to start with. It is my intentions to get them to run their mail and website locally instead of a hosting site.

This will be the test just as the firewall was which is now corp wide at all plants (my config files).

That's rather marvellous. Kudos to your bosses for having the bottle to trust their admins and go with Linux. Let us know how you get on.

1st report

The samba server and DNS went off without a hitch.
An "old" 233 P-MMX got a new life. Added a 10/100 full duplex nic, 128MB, 2GB / drive and a 8 GB /home drive. Hand hacked the the smb and named files after a smooth install of Slackware 10.
Set the Samba server to force an election (which was rigged to slacks favor ) as master browser.
As soon as the slack box was active on the network the "crashes" stopped (all those blinking lights settled down).
Went around to all the win boxes and assigned them more proper names and addys to match the DNS zone files. I also mapped network drives for the sales and production homes. Was done by lunch time....

There has been a marked increase in speed on the LAN. Also they like the fact that the company files are now under a "secure" roof and not scattered across a dozen machines.
They have been impressed with the firewall and now are amazed at how "easy" it was for me to make a server and have it running smoothly in one day.

Gotta love the power of Linux, I do...

Excellent stuff - nice one. You next task Agent Penguin () is to get your company to fund your Linux traning - RHCT/RHCE/RHCA/LPI/etc - because it is in their best interests

Glad it all went off ok. How's the firewall/IDS/etc?

The firewall works real well. They provided the device which is a D-Link dfl-300, You can tell by the webGUI it is a Linux based iptable embed. It was troublesome at first and required a firmware upgrade straight out of the box. It is highly configurable and requires a bit of knowledge about firewalling and not for your "average" user. One of the more unique features is the embeded dyndns.org software. That is my next project. (dyndns linking).
My goal is getting a fully qualified DNS running for the entire company, then bring up mail, followed by website hosting their own site (hosted with hosting service now as is mail). If I can get them that far (slowly, off the shelf equipment) and I must show them saving $$$ (they really like that)... I would like to have all 4 plants with local DNS with a primary bastion DNS w/slaves This would really be useful as I could expand the Samba server to reach out across the inet and bring in all 4 plant as the whole domain.

The greatest challenge will be getting the job of the NT4 servers. the mv-base Their mv is HUGE and their is not a soul there that knows the first thing about programming (me included). I think it is silly to still rely on modems to pass this data around the 4 plants US wide. After my modem up grade they have at least gotten new 56k modems for all plants. There is still a problem with pooling not related to the modems but at least now when the servers do poll more info get through.
I want to bring this to linux and via dyndns of the dsl and fully qualified DNS I can then link the mv-base servers across the inet and thus save them long distance phone charges and make a more reliable system...
and That may be the hardest thing to get them to try....

Wow. I hope you get a substantial pay rise for all this. Seriously.

I hadn't realised companies were still using dial up. Even the UK government has moved from that, through ISDN to reasonably fat pipes. A few years after everyone else, naturally

What is the mv-base? Is it a database? Have you considered leaving it on the servers (maybe after downing them and rebuilding them - I have seen it recommended that you completely reinstall Windows at least once a year to make it stay working) and use a thin client to access it?

How are you backing up the servers - local tape/whatever or centralised backup?

Whatever you do, it sounds like it is all going swimmingly and sounds like you will be very very popular for a while with your management.

They back the NT4s up daily to tape. One of the problems that arose last week was a server crash and a tape backup restore. The backup was corrupt.. They have been using the same tapes for 2 years. So that has been a problem.
mv-base is a mulitivalue database system developed about 20-30 years ago I believe on a "pic" system. Just our end alone is nearly 4GB. This is "suppose" to run on unix flavors natively.
Yes they have considered upping the windows servers from NT to a more recent version and upgrade hardware.

Their next to the last IT was "selling" leased server time to spammers on a server they where leaseing on the net. They are still fighting blacklisters over that.
The last IT could not handle the pressure. That is when they got me involved due to my "home network". Now they have an IT at the main plant and I am the NETWORK IT and SysAdmin of course I still have my primary duty of being the plant Engineer also. Then today they drop the PO system in my hands... Talk about multitasking... lol

Definitely push for a pay rise or a bonus or something. Not an "ataboy" umm "attagirl" umm "attastaffmember" () though - something both tangible and substantial.

Backup tapes are a nightmare - you never know they are borked until the point when you need to restore something. How's the cooling in your server room?

More good stuff

The "server" room is cooled by its own AC... Very cool for the machines.
I now have a DNS server up and am expecting more info from the out plants as to their machine names and addys. I will go from there to get them on a more standardized track.

Also the plant manager is going to take over a new upstart plant in the Carolinas as has ask me to get him up a quote on building and installing a full Slack driven network!!! AND what I would charge as a remote administrator!!! Talk about dreams comming true... sweet real sweet...
