I'm having trouble configuring my amd64 boxes as NIS Clients. The ypbind daemon can't connect to the server. x86 boxes on the same network can. All are running SuSE 9.1, in appropriate x86 and amd64 versions of course.

I'm baffled. I've tried running ypbind -debug, but all it says is repeated "yp ping" of the NIS servers, which seemingly don't respond. As I said, only my amd64 boxes have this problem.

Are there any known issues with NIS and amd64? I've tried following various troubleshooting guides I found on the 'net, but I'm no NIS expert and I might of course have overlooked something obvious.

Any hints, please?

I've got AMD64 NIS clients, have used SLES 8 in the past but have migrated all of them to SuSE 9.1 over the last couple of months. I never ran into problems of any sort. 1. Are you using broadcast or specific IP addresses to identify NIS servers? 2. What's the firewall setup on the clients? 3. As you restart the ypbind daemon, does 'netstat -ut' on the server show anything useful?

Lennart, If you'd quoted properly (http://www.netmeister.org/news/learn2quote.html) someone else might have answered while I was away travelling. Or I might have answered sooner as doing so would have required much less editing. Top-quoting is evil, it may save you a little time but will deter a lot of people from responding.

1) Specific IP addresses or rather the names of the servers. I've tried broadcasting too. BTW, the configuration module in yast does not find any servers either if asked to scan for them.

Use IP addresses, not names. You don't want to be dependent on DNS for NIS. Trust me on this. Should be fine. You did set this up using yast2, I presume? Is the client and server on the same subnet?

2) Default firewall, i.e. I've not configured anything explicitly. Basically a fresh install out-of-the-box of SuSE Pro 9.1. I believe this should equate no "no firewall"?

No, all the recent SuSE-versions have come with a firewall running. Since it kills nfs I always disable it immediately and run my own scripts. The firewall is fairly tight, and the default config seems designed for the single machine home user. Whether it prevents NIS I don't know - but your log snippet indicates that there's no stopped traffic.

3) netstat on the server shows no incoming connections.

Anything in /var/log/messages?

On the client, /var/log/messages says:

Is the portmapper running? 'ps aux | grep portmap' should get you the answer to that. And you _are_ running ypbind in broadcast.
