[9fans] dnsquery or search

2008-09-18 Thread yourfriendllc
I see that ndb/dnsquery returns correct information on my system, but I noticed that there is not a default domainname, like on linux, in / etc/resolv.conf we set the search domainname ... is there a similar setting in plan9

Actually, this whole subject was thoroughly discussed at the *first* iwp9; but apparently nobody is bothered by this enough to implement any of the then suggested solutions. Op is not one the solutions discussed at the time, and saying 'just use another protocol' is not a way to resolve the

There's is some code laying around for Broadcom 570x cards: http://plan9.bell-labs.com/sources/contrib/uriel/mirror/bc.tgz I'll take a look at it. I seem to recall some discussion of it and that it was in a pretty incomplete state. If I'm remembering correctly, I'm thinking my chances might

I was using a 3c589 until a few years ago, then I moved to a Netgear FA411 which is somwhat more mechanically robust - I broke the plug on the 3com card :-( It sounds like for a number of people it's working just fine, and no one's put forward any real magic to make it work, except for using

I'm not saying I know it would be a good idea, but you could implement speculative-9P which issued the equivalent of the batched requests without waiting for the responses of the prior request -- since you are on an in-order pipe the file server would get the requests in order and if they all

We did this, IIRC. It helped reduce latency, but... Are the modified kernel files still in your venti? I would be interested in having a play in a simple disk file sharing environment. -Steve

I think I made it using a user-level program to talk to 9p servers trying to do some caching. I'll try to find out if I still have it in venti, I think I just removed the thing after finding out it was not going to work for retrieving omero trees. On Thu, Sep 18, 2008 at 10:05 PM, Steve Simon
