RE: [SLUG] Networking advice please.
I have 3 pc's networked to an ethernet switch, which is connected to the 'Net via a modem router. All works well. You mean the internet connection works well? My house was cabled for LAN with cat5 cable when it was built. I have connected a pc to each of 2 LAN wall outlets ( in different rooms) with a straight-through (ie not crossover) cable, and have tried connecting the ethernet switch to each of the 4 outlets at the LAN outlet point at the other end of the cabling in my Den. The appropriate set of lights on the ethernet switch fail to light up, no matter which of the 4 outlets at the wall junction I attach it to, even though the other end of one of these outlets has a PC (in another room) attached. Does the green light on the network cards light up or flash when you connect them? If there is no green light on the NIC when you connect the cable (through the house) that means that the connection is defective, most likely caused by the cabling. The way to prove it is to get all the pcs in one room and plug them into the switch. if the green lights come up on the NICs connected directly to the switch then you can be certain it is a cabling fault. Either all of the LAN cabling in the house is defective (unlikely as the other cables for Cable-TV and TV Aerial work), Not the same cabling as network (cat5 or RJ-45). or I am doing something wrong re connecting the remote PC's to the ethernet switch. not likely, but the switch could be faulty. Should I be using straight-through cable or crossover cable from the wall point to the ethernet switch (I asume straight-through)? How can I test the cabling, short of purchasing an appropriate cable tester? plug 1 piece of cable you know to be OK between network port of 1 nic that you are certain works (e.g connected to modem router) and one by one to other pcs. preferably cross-over cable. if the green light comes up again then the nics are OK. If it's not the cabling or the NICs then the network isn't setup correctly. :) Thanks in advance.

If you are not getting a connection I would check the cabling - check the patch cables first. I know you don't want to buy a cable tester (however, a simple continuity tester is only a few dollars) but without such a device you could be spending a great deal of time and still not solve your problem.

Why not take the switch to the pc use your straight through cable to connect pc to switch to see is the lights come on. If it does, it still might be the card or the cable. I would presume the cable first, easier to test this. once you do get conectivity then tack the switch back to the orginal place and connect via your patched cable if it now fails then its the patch LAN cabling.

Re: [SLUG] Networking advice please.
Someone much smarter than I, on Wed, Jul 14, 2004 at 08:14:28PM +1000, spake thus. *SNIP* My house was cabled for LAN with cat5 cable when it was built. I have connected a pc to each of 2 LAN wall outlets ( in different rooms) with a straight-through (ie not crossover) cable, and have tried connecting the ethernet switch to each of the 4 outlets at the LAN outlet point at the other end of the cabling in my Den. *SNIP* Why not take the switch to the pc use your straight through cable to connect pc to switch to see is the lights come on.

I'd have a good look at the cabling to your wall outlets. it's quite possible that someone has inadvertantly made it crossover rather than straight through. just a thought, -- Shaun Oliver I refuse to have a battle of wits with an unarmed person. email: [EMAIL PROTECTED] WEB: http://blindman.homelinux.org/~blindman/ IRC: irc.awesomechat.net: IRCNICK: blindman -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Networking advice please.
My experience over hundreds of such installations indicates this: If your Cat5 cabling was installed by your friendly local electrician, you may find she/he has made the connection incorrectly. You will find that the NICs and the 100BASET switch will indicate that the physical connection is there (appropriate LEDs) but data will fail to be transmitted. Incorrect termination is most easily proved by the use of a 10BASET hub or switch which in almost all cases WILL work over incorrectly terminated Cat5 cabling. 100BASET will NEVER work over incorrectly terminated Cat5 cabling.

Often those things have 5 ports, but only four can be active at the same time (the extra port can be used as an uplink port, disabling usually the number 1 port). Should I be using straight-through cable or crossover cable from the wall point to the ethernet switch (I asume straight-through)? Generally PC-switch is straight through, but most equipment these days is auto-sensing and will just figure it out. -i [EMAIL PROTECTED] http://www.gelato.unsw.edu.au signature.asc Description: Digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Bill By all works well I assume you mean pc's networked to the ethernet switch NOT via the wall cabling. If the switch is a fairly recent purchase, then it shouldn't matter if you use cross-over or not - a lot, if not all, of soho switches auto-detect cross over or not. Theoretically, the wall cabling should be straight through and so using the cables you used to test the ethernet switch with the pc's should suffice. Cable-tester: borrow one Try each of the 4 ports on all of the ports on the switch. Nothing else comes to mind.there's not likely to be 100M of cable between the switch and the computer is there? 100M is the theoretical limit.
