nwip

By rappenp ·
I'm have problems with nwip. it seems every packet that goes over the wan leaves the machine IPX then nwip converts it to IP sends it to the router (router only handles IP) then nwip on the other side converts it to IPX. needly to say this sucks I only get about 2-300 packets a second.

Can anyone tell me how to speed up nwip, do away with it (mostly 4.11) or point me to info on nwip to help me understand it.

Basicly nwip encapsulates the ipx packet within an ip shell. That process and the decrypt are what slows you down. Unfortunately, you will not be able to speed things up very much if your routers can't handle ipx. To do away with nwip, you have two options.
1. go straight ipx, and get routers that can handle ipx.
2. go straight ip. to go ip you will need to upgrade to NW5. NW5 and above are native ip and you will be able to run ip only.

Not great options, but your right, nwip sucks.

OK your telling me pretty much what I know. I'm looking for a easy way out that won't involve visiting everyone of my remote site (200+) more then I have to. It's planned to update them to 5.1. but even the sites that have been updated to 5.1 only work IPX if I only have ip loaded the client can't see any of the server. Can't Netware take IP and IPX at the same time. or am I missing something??

It sounds like you don't need NWIP. You can accomplish the connection through the routers with Novells IP-Tunel functions and leave of the rest of the overhead NWIP needs. You will need IPtunnel.lan loaded. The documentation on how to configure this shipped with the Add-on TCPIP for 3.12
If you cannot find the documentation, email me and I'll send copies of autoexec.ncf and the required IPtunnel.lan. I have installed this on 3.12, 4.10, and 4.11 servers with very acceptable performance.

I will look into iptunnel, I still sceptical because I don't understand why my IP clients can't login but IPX clients can, if I remove the ipx completly from the server then ip clients can log in, but only local not across a router. I believe iptunnel works in conjuction with iprelay and iprelay needs RIP which I'm not using.

Try this on a remote user that is set up ip only. Under the netware client set your prefered server to the specific ip address of the server the user is trying to reach (177.77.7.7 for example). Enter the Tree and under name context enter the complete route (corp.mynetwork). This should get you through to the server, I've had this problem before and this fixed it.

I have tried that, it didn't work. I have since found out that there is a conflict in the way things are named. the DNS is hosted out of house. and the name that nwip uses is something else entirly. surprisingly they igore the DNS name and go with the name of the NWIP server. maybe I'm just not hitting the right name server? I've tried to get around this by using a host file. this works to ping and resolve the name but you still can't log in.

I have seen several problems with NWIP, it is not easy to configure, especially if you are not controlling your entire WAN. I actually have a question for you: Have you installed NWIP on the workstations?? This is a solution that was employed by a previous employer. It took months of configuring and tweaking to get it right, and in the end, only partially worked. That employer is currently switching to NW 5.1. I know this won't help, but good luck.

Sorry this took so long to get back on this other projects on the burner. I have configured a nt 4.0 workstation box with the 4.8 client/with nwip local.. this work somewhat better but after sniffing it, and looking at the trace. it has some problems. it's slow at browsing because because it sends 8 packets to the right ip address wrong port (port 7 echo) recieves 8 message back that the host is unreachable, then it try a different port and get right in.

There isn't any DNS inside this network, I had to use a HOSTS file.

I'm left with a few ?'s

How does NWIP/Netware decide on a port to use when setting up a link, how do you configure it.

If your using a HOSTS file how can you include a record for the tree as well as the server.

The only way to do away with NWIP is to upgrade to NetWare 5, then you can do away with IPX.
