Network Layout ???

Crashed_Again · 05-14-2003, 10:40 AM

Hey all. I recently posted a thread asking how many machines you had running at your house. As a follow up I was just wondering the architecture of some of your home networks. I realize that some of you may feel that this is sensitive information so you don't have to tell us. This is not some form of social engineering.

I'm just curious...

MasterC · 05-14-2003, 10:51 AM

Yeah sure it is. Next you'll "randomly" ask:
"So everyone, now that I know how many machines you have, and your network setups, as a continuing question I was wondering who had the longest IP"

Then from there it's:
"So, now that I've hacked nearly all of you, as a continuing tyranical rage, let's all post up our addresses and see who lives closest to me".

Just kidding of course

I've got 2 boxes (woohoo, just added my second last week). 1 running Duron 650 w/64MB RAM (the new server)
and 1 running Athlon 900 w/640MB RAM (The workstation, currently gaming alot

)
These are networking using NFS through a Linksys BEFSR41 and 2 Nics, one using the Realtek 8139too module, and the other a Tulip (Linksys). I use DHCP to obtain my IP from my ISP, so my boxes both use static NAT/generic IP's. I do not have a keyboard or monitor connected to my "server" so I ssh into that.

Cool

Two boxes, a pIII @ 450 and a athlon XP @ 1400. Both have a linksys card (tulip module) and static ("home") IP's and the athlon has a an additional Realtek (8139too module) to connect to ISP via DHCP if i EVER get ADSL... Used to have NFS, but now i just ssh from one box to the other, and of course, games! OOh yeah, theres a 5port hub to which both NICs connecting the two boxes are connected. You need IP's too

Total Network Layout including my roomates machines:

Code:

Cablemodem > Linksys Wireless router
                         |    |__ stardust ( slackware 8.1 -desktop )
                         |    |__ gemini ( slackware 8.0/win2k -desktop )
                         |    |__ lotus ( slackware 8.0 - file server )
                         |
                         |__Linksys 8 Port Switch
                               |    |__ blackhole ( slackware 8.0 -webserver/FTP/ssh access point )
                               |    |__ orion ( slackware 8.1 -FTP server/Samba )
                               |    |__ asteroid ( redhat 6.2 -no defined purpose yet )
                               |
                               |__ Linksys 4 Port Hub
                                          |__ smoovet ( win2k -roomates )
                                          |__ daniel ( win2k/redhat 7.3 -roomates )

All of my Linux machines I use NFS to share files between. And the majority of them use Linksys NIC's. I think I have one which is a Realtek card, forgot which one off top of my head though. And none are using Wireless right now, friends that come over usually will use Wireless to connect.
If you can't already tell, I'm bored at work..

manthram · 05-14-2003, 01:46 PM

I have three machines and two laptops ( including my roommates)

server : Mandrake9.1: 533 celron with two nics ( realtek and some other nic using tulip ) gets dynamic ip form ISP and nating the internal network.

desktop 1 : winXP/Mandrake9.1/Win2k server: 1.9GP4, two nics
(realtek and natsemi) one connected to hub and the other to wireless router.

desktop2 : win2k/redhat 9.0 : 733 PIII :

laptop (MINE) : 650 PIII : mandrake9.0/win2k wireless PCMCIA card so that i can use it both at the office and home

laptop (roommates) : 1G PIII : redhat 9.1 (intalled last week after i convinced him to try linux)/win2k. also wireless PCMCIA

i use basically ssh to connect to the machines. firewall generated by fwbuilder, but of course i customised the script later. just lazy to write it form scratch.

so what is your layout Crashed_Again??

Crashed_Again · 05-14-2003, 10:26 PM

cli_man · 05-15-2003, 06:45 PM

Running 4 Machines at home right now:

1 - Duel 450 Mhz PIII 4U rackmount server, running Redhat 9.0, 3com card plugged into a 4 port hub that is plugged into my cisco 677 dsl router. This machine is used as a test machine for my servers and also I do my remote programming with this machine.

2. Sun Blade 5 400Mhz with 8 gig drive, running solaris 8 using KDE as the GUI, Currently just trying to figure out Solaris on this machine. It is also connected to my 4 port hub from above. This machine is for sale if anyone is looking for a good sun solaris machine :-)

3. Compaq 1200z 1000 Mhz Athlon Laptop, Duel boot of Windows XP (Primary) and Redhat 7.2 This is my wish machine, I wish I could get it on the network in linux but the network card won't work :-( But in Windows I have it going through a Wireless Access Point that goes into my DSL

4. Compaq Oddball number Laptop 1.4 Ghz Athlon, Also a Duel boot between XP(Default) and Mandrake 8.0 This machine is used abit for programming, but mostly just graphics in XP.

5. I am working on a little print/file server to through backups to and also use as a print server at my house, just haven't taken the time to put it together yet. It will be running Redhat 7.2 though.

And all of my machines connect through NFS to my servers where I work (I'm Linux Sysadmin there)

cokeonice · 05-16-2003, 12:44 PM

I have DSL access to Internet.

DSL Router
LinkSys Router
Network Hub 10/100
P200, 128MB RAM, w/Win95
P4 2.0, 768MB RAM, w/WinXP
P4 2.0, 768MB RAM, w/WinXP (sons)
(the above two machines are mainly for gaming)
AMD Athlon XP 1800, 512MB RAM, Mandrake 9.0 (webserver)
AMD Duron 1300, 512MB RAM, soon RedHat 7.2 (workstation)
IBM AS/400, 9XXX-200, V3R1 (old but it still works)
and one 486DX2-66, 48MB RAM(?), MS-DOS 6.22 (not networked though)

Just some basics. The full specs on the machines could take pages and who wants to read all of that?

I have a real nice Visio layout for my overly complicated network, but I will try to describe it here.

Cable Modem connected to Broadband router (A) Serves DHCP with fixed mappings.
Wireless Access point router connected to (A) for Laptop [XP/Topoligi] and PDA[PPC2002]
Serving DHCP

Smoothwall [P75 with 32mb ram] Firewall with Red, Green and Orange, red is connected to (A)

My Workstation [XP pro] and my wife's[98] are connected on the green (DHCP) through an 8 port switch as well as a IBM 1452 and an ACER 486/75 (laptops) looking for an OS.

Windows 2003 Enterprise Server is connected to the orange side running IIS, FTP, and Xmail ) through an 5 port switch.

I also have P233 with 192mb ram that I want to use and an apache server with jboss. I am having trouble getting an distro to load on it, but I'm still trying. I had Morphies loaded on it but I didn't like the debain set up. Slackware wont boot on it, Mandrake and Suse locked up, now trying Redhat before just slapping FreeBSD on it and calling it quits. It's in the green side now, but will eventually end up on the orange side.

Yes, I have a DMZ in my basement and 9 computers in the house!
Just a

Crashed_Again · 05-16-2003, 02:15 PM

Wow I am very impressed with some of your setups! I only have one machine at the moment but my friend, who is die-hard M$, called me today and said he has an extra machine at his house. He wants me to put Linux on it so we can run a webserver for some sites.

muhahahahahah...

Another convert.

Anything else that gets turned on gets a spot on the hub behind the NAT machine.

Crashed_Again · 05-16-2003, 03:09 PM

Wow now that is impressive. Which one is the NAT machine? How do Ruprecht and Orwell get connected to the hub? I though you could only have one input to the hub.

finegan · 05-16-2003, 04:32 PM

Its a really old cruddy hub, and I've got the WAN port switched off so there are lots of collisions. Both Ruprecht and Orwell NAT, occasionally, it depends on the week. Tenacious also NATs for the wireless network that is entirely seperate from the wired network, gotta remember, I've got 5 static IPs. Actually, the DSL router only has 4 ports and the WAN port from a fried Linksys Router (now an effective switch), is hooked up to the DSL router so Ruprecht and Orwell are on the Linksys salvage toy and the other three are on the DSL router. Ruprecht and Orwell both have 192 access and a pair of cards as everything in the house backs up to Ruprecht. Orwell rsyncs effectively through the www along with Nimble, while Tyler rsyncs through the 192 network. Its all piped through ssh, but there had to be a lot of kludging done so Orwell could sync via 100Base-T over the fried Linksys router. Ruprecht is also the mp3 server and generic file dumpster for the network as it has the perverse drive space. Ruprecht's purpose on the www is kinda pointless as Apache is switched off and all the mail it gets is forwarded onwards, mainly I use it as something to ssh into and irc out of from work. Muffin is a friend's server running something stupid, like 10 domains, Orwell is clockwatching.net, and Wolfwood is just bloody near impenetrable, which is a nice thing to have on a network if the fsck hits the crc32 bug. I really should build an invisible network packet filter for all of them, but I haven't really got the urge to crank the power bill up another notch.

Cheers,

Finegan
