There is no ping in SymbOS Wink So that woudn't help Wink

I was not talking about the local subnet, what i mean was, resolve the domainname: network.symbos.org on a different PC than on the MSX and use the IP (87.106.252.130) in the chat client to see if we can connect to it without using DNS on the SymbOS workstation. Maybe i was not clear.

That's harder, because your network names are not using DNS but usually NetBIOS in a Windows network, or even a Linux network with a Samba server with Master Browser option enabled, and probably that is not implemented as it could get many resources. Nslookup will not find your local hosts unless you have your own DNS server configured in your LAN to resolve those names. External DNS servers will not know anything about your local network so they will not resolve.

Anyway.. as it seems to work on my setup with the latest GR8NET firmware i think there is something else wrong. I suspect the gr8net daemon in SymbOS. As since the introduction of the mapper mode on the gr8net we build a new driver for it, which supports the mapper mode on the SymbOS side. So i think there is a old version used. But.. that is the question.

No Ping is an important lack for network testing. Shocked that the most basic command was not included.

Yes it is Wink Because ICMP is currently not included in the daemon as we focused on TCP and UDP first.

Hi Edoz, thanks for your help, finally I could test. Ok, here are the results: everything is ok acording to your indications, even daemon (I start gr8net daemon). However I've done more tests and I've seen following: depending on conection, it works or doesn't, I explain.

Right now my GR8net is conected to a PLC. With this config, GR8Net has network but SymbOS not, quite strange. I've plugged a Lan repeater and I've shared my smartphone wifi with it, so Gr8net is taking internet from my smartphone. With this config the situation is the opossite! SymbOS HAS internet but GR8Net hasn't!

Conclussion: the problem is in some way the way in which my network device works, so I need to explore options in my router.

I forgot to mention, problem is with DNS. Using direct IP I can do telnet to hispamsx for example, but no way using name. and use manually 8.8.8.8 as DNS server doesn't works, it's quite strange.

If DNS is slow (response in more than 2 seconds) then GR8NET firmware will give an error. It is usually the best to be on router with DHCP as routers also usually provide DNS services (and have cache for DNS requests and responses). Ping DNS server's IP address in your latter configuration (if it can respond to ICMP) to see the timing.

In both cases, GR8Net basic and SymbOS, the router is configured as DNS server, this is 192.168.0.1 in both cases. GR8Net solves correctly names, I can do this:

_NETTELNET("bbs.hispamsx.org:23")

And works perfectly. With same config in Symbos (IP = DHCP and DNS = DHCP, it takes router as DNS server as I said) I can't resolve any name, but I have internet access. If I try:

telnet 88.9.174.172

I enter hispamsx bbs. In some way seems that SymbOS driver and my router don't use same "language" to negotiate DNS. It's quite strange because I assume that SymbOS driver should be a simple wrapper to GR8Net DNS function, is this right @Edoz?

Thanks.

forgot to attach image, here goes:

As you can see, detection of DHCP is fine. That config is exactly the same shown during gr8net boot (same ip, same dns).

Hi AxelStone, sorry for my late reply.
Did you try NSLOOKUP in SymShell? Does it return any error messages?
The network daemon (GR8Net version) currently doesn't support "recursive DNS servers". It doesn't use the DNS function of GR8Net, but it is sending UDP packets by itself.

Maybe the gr8net bios supports recursive DNS , that could explain the mixed behavior.
