Current network mess
Network map | 
Room | 
Network gear |
I just completely reorganized my computer room a couple weeks ago. There used to be cables all over the place... and now there are STILL cables all over the place. Oh well. This is actually a "before" picture for the work I'll do on it this summer, which involves retrofitting the house with Cat5, installing a "NOC corner" in the basement(with much better equipment), and hooking up the rest of the server and stuff. Unfortunately, I only have an 8 port 10/100 hub right now, so some of the things here aren't hooked up due to that limitation. The computers, (from left to right) are: -2U rackmount server. No purpose quite yet. Will be an IDS server along with some other things though. -Windows gaming system. It was built a year ago, and still works great for new games. Athlon XP 2600+ or something. 1GB ram, the Radeon 9700 version that came with the monster heatsink/heatpipe thing. Windows XP -Linux workstation. Posting with it right now. Athlon XP 2800+, 1GB ram, 180GB HDD, Gentoo Linux. -Web server. K6-2 450, about 320MB ram, and 2x8GB hard drives. The left monitor is for Linux workstation, and the right is switchable between the rack server and the windows box. There is also some other stuff like a big UPS array and a ham radio station (well, kind of) in this room that you can't see in the photos. |

Can we see the laptop and the UPS array? Thanks. Nice setup, btw. |

Looks like you are using a cisco 2541 can you post your routers config? I'm switching from cable to dsl and would like an example config |

UPSes | 
Network laser printer |
I didn't get a picture of the laptop or other workstations since my camera batteries died, but here are the UPSes and laser printer. The UPS at the left is the main part of a matrix 5000VA. This isn't actually plugged in yet, but will be the UPS for the equipment in the basement I'll be putting in this summer. I need to get a suitable 250V circuit wired and buy the batteries. The other UPSes are a Deltec 1920VA, an APC 1200VA, and an APC 800VA with a larger battery pack. I also have an old 6000VA UPS just sitting around elsewhere, but I'll probably just sell it. I got all of these used for a total of around $150 from different places. The printer is just a Samsung laser printer with a built in printserver. |

The cisco 2514 router is recent. Actually, I just got it set up a few days ago, and that was how I found these forums. The people in the CISCO forum were extremely helpful with this. I'm running IP FW Plus IPSEC 56 IOS, so I can do stateful packet filtering. Here's the config right now: !

I have a plain old ethernet dsl bridge, and a single static IP. If that's the config you have, you can probably just put in your own IPs in there, and it should work. Again, you'll need the FW IOS image. I also have this set up to forward ports 80 and 23 to an internal web server. Port 23 goes to 22 on the web server, though. |

Whatever you do, make sure you don't plug the Laser Printer into the UPS  Can cause major issues... |

Great! Although its actually a 12 year old keyboard, manufactured 6-18-92. The one on the right was made in 12-4-95, and is a Dell branded one. The Dell clone doesn't have the removable keys, but has the same feel as the original one. The Model-M keyboard is pretty much the "king of keyboards" in my opinion. I'll go with a new mouse, new monitor, new whatever, but I'll keep the Model-M! "Its not a REAL keyboard if it can't effectively be used as a weapon."(or something like that) - A friend, when looking for Model-Ms. |

What is xfig? said by Cyberprog:

Why shouldn't you plug a laser printer a UPS? |

Xfig is a Linux vector graphics editor. Its good for making network diagrams and stuff.
---
Laser printers press the page at hundreds of degrees farenheit, using a fuser, to bake the toner into the page. The heater for this usually works in cycles, but draws a lot of current when it comes on. Generally, it will at least draw several hundred watts on a slow printer, and more on a faster one.
That current draw is enough to overload small UPSes and force them to shut down. Although larger UPSes, like the bigger ones in that photo, can handle a laser printer without a problem, it is still not a critical system and is usually a big waste of backup power. So generally, you don't plug a laser printer into a UPS without very good reason. |

O ok. I see.
Is there anyway to run xfig on a Windows system? |

yes their is, get a Linux Emulator Use something like VMWare or Bochs. Although Bochs sucks. |

Typically, laser printers take a lot of power when the image the drum. When that happens and it is plugged into a UPS, it will reset the UPS and cause a few seconds of power loss, power cycling any machine hooked up to said UPS. |

The second monitor should be replaced with something more modern. I mean CRT monitors are so cheap these days. I bought this one for $109! |

Dont tell me you are using the right monitor to play games on!, Why not KVM the windows and the linux, and have the right monitor be Server only, instead of having the server and the gaming be KVM'ed. |
|
| |
I would have done that, except that the KVM switch is really crappy and causes a lot of interference at high frequencies.
The Linux box is running at 1600x1200, and the Windows box is running at 1152x865. I can cope with a slightly wavy UT2K4 game, but the wavyness at 1600x1200 is way too much to do any serious work with.
As for the IBM monitor, I got it a few years ago for $40 used. It still works, although its getting a little blurry. What can I say?
I keep wanting to get some really nice monitors, but I'm waiting for a really good deal to come along. I'm thinking along the lines of four 21" ones. |
