Ping, Amiga<>PC LAN, dual Ethernet cards, filesharing probs & fixes

[ChaosLord]

I had a perfectly working LAN between my PC with WindowsXP SP2 using builtin ethernet port and my A1200T OS 3.9 with Samba (Mediator PCI Ethernet card)

Then I got DSL so I had to disconnect the LAN cable so that I could connect the DSL modem.

Ever since that day, no matter what I do, I can't get my LAN reconnected  :bigcry:

I currently have 2 ethernet ports in my PC.  1 is the built in one.  The other is a new PCI Ethernet card.  They both work perfectly.  I know because I have been online thru both ports.

So I figure there must be some secret setting in XP that flipped itself and I need to flip it back?

The Amiga was not moved or tampered with in any way.

Anything I should check?

Well, for starters, each computer in a simple PC LAN environment, known as a workgroup, must be a member of that workgroup to "see" each other. Crate a workgroup name something like "mylan". Join all computers to that workgroup and you should be good to go. Also, be sure to set your router to supply the lan scheme IP addressing by enabling DHCP. Hope this helps a little. BTW, you do have a router, right?   ;-)

I use static IP between the Amiga and PC.  Ensure that the Subnet Mask is consistent between all the connected network equipment and the Gateway IP is consistent.

Also ensure that the IP addresses use the same format on each computer.  Enter the IPs / Computer names in to the hosts section on Genesis or Miami.

Also ensure the Workgroup name is consistent between every computer and Windows XP accepts shared access on the folder you want to share on the network

Example:

DSL Router
----------
IP address: 192.168.0.1
Subnet Mask 255.255.255.0

PC
--
IP address: 192.168.0.2
Gateway: 192.168.0.1
Subnet Mask 255.255.255.0

Amiga
-----
IP address: 192.168.0.3
Gateway: 192.168.0.1
Subnet Mask 255.255.255.0

Of course they are in the same workgroup!
How else would my LAN have worked all that Time? :crazy:

I am not using DHCP.
Each computer has its own static IP address.  Just as it always has.

I am not using a router.

The 2 machines are connected Directly together via a crossed Ethernet Cable which is still new.  I just bought it a few months ago.

As I said; it was working perfectly, now it is not.

The only thing that changed was ... I setup for DSL which uses a stupid PPPoE connection thing... so in the process of setting that up I think maybe something in XP got turned off.  I have noticed that XP changes settings without my permission sometimes.

Any ideas?

This is not required for networking to work. Ping works just fine regardless of workgroup.

Thus, this cannot be his problem.

Just fine.

The only thing that wouldn't work would be the samba connection. Ping, and every other network connection between the computers would still work.

Anyway, regarding the problem: One possibility is that the XP firewall has for some reason figured that your system must be blocked. Try temporarily disabling the firewall and see if you can ping then.

When I first read this, it sounded like he had two PC's and an Amiga... I figured that he was already direct connecting the two PC's. Introducing a third computer would require some sort o router. BTW, in XP with a router/lan setup, all computers must be in the same workgraoup to browse and share. Sheeesh. Just trying to help. Why do some peeps here always feel the need to "out-smart" the other guy?   ;-)

My Windows XP firewall has never been on.  I don't trust it.

When you say 'disable' do you mean clicking the OFF button?
(it always has been off)

I do use Kerio Personal Firewall... ok I disabled it.  I still can not ping.  BTW it is excessively dangerous to turn off the firewall while online with Verizon DSL.

@gizmo350

Just because it obviously cannot be a workgroup problem (just think about it for a second, wrong workgroup can't block ping!).

@ChaosLord

If your system has the security updates upto date and doesn't have passwordless network shares open to everybody, it should be safe for testing.

Anyway, you should try isolating the problem a bit. Try connecting the amiga to some other system or the DSL directly (if only possible), and see if that works. It helps if you can rule out some hardware from the equation...

Yes good idea!

...

but one small problem...

Verizon DSL sux and requires PPPoE.  So I would need a PPPoE client for Amiga. (preferably for Miami)

I had my A1200T on DSL in my old Apartment since 2000 but that was using SBC DSL which is super ez to connect to.  Just plug it in and go.  I never should have switched to Verizon.

Alternatively if you have some 2nd pc you could try replacing the amiga with it and see if that works (just remember to config the static ip to one used in amiga 1st).

That's true...  I guess I was really wondering if he was using a router.   :-D

hmmm.... interesting idea!!!!!!!

It just so happens that Santa Claus dropped a brand new Linspire PC in my closet. :-D

Is it easy to config Linspire TCP/IP settings?

[ChaosLord]

My gateway is 192.168.1.2
That setting is the same on all Ethernet cards including Miami.

Is it ok to use that address?

[ChaosLord]

Ok I hotswapped the DSL Modem cable out of the PC and plugged it into my A1200T.  Then I pinged the modem.  It works!

This proves that my Amiga+Mediator+PCI Ethernet card all work great!

So the trouble is either:
A: Windows XP is blocking pings and all other communication to/from my Amiga.

B: My brand new crossed ethernet cable has suddenly gone bad.
