Hi,
I received message from the NIS service on a 2.2.5-beta
workstation and a 2.2.2 NIS server.
The 2.2.2 NIS server say:
ec:/var/yp<-' make
NIS Map update started on Mar 14 oct 1997 12:10:30 EDT for domain ec
Updating mail.aliases...
/etc/aliases: 36 aliases, longest 762 bytes, 3341 bytes total
yppush: Transfer of map mail.aliases to server beta.ec.camitel.com failed.
yppush: status returned by ypxfr: Domain not supported by server
Pushed mail.aliases map.
NIS Map update completed.
ec:/var/yp<-'
And at the boot time, the 2.2.5-beta say:
rpc.yppasswd:can't get name of NIS master server for domain ec
the NFS work fine.
but I make an ypcat aliases, I can see all my NIS aliases.
But if I try to send a mail to one of my aliases, the mail comme back with an er
ror. The mail cannot find the aliase.
Do you know what is the problem ?
I have 5 FBSD machines on my net and all work fine with NIS.
================================================================
An other problem with PPP.
PPP hangup at random + bad Performance
I ship this mail because I want to have some feedback from persone that use FBSD
for make a Modems server.
We have two net. In two different city. With different kind of modems.
We use at both place a Cyclade 16y serial board.(cy0)
And we use also at one site,
3 internals modems that use sio1 and sio2 ( GVC and USR )
One year ago, we used FBSD 1.1.5 at both places. On a 386-25.
We have successfully install the cy0 driver in this version of FBSD.
This version work with some twist and loopback in the serial cable,
but it have finaly work after many days of labor.
With 1.1.5, I am able to reach 4.2K/s with our ZyXel OMNI288 modem.
We have make our download test with FTP and do a GET of the /kernel.
I dont know if the density of the kernel have change, but if I try the same test
with 2.X.X, I am only able to reach 2.2K/s a more powerfull 486DX4-100.
Same problem on sio and cy0.
First we have think our modem are guilty...
We have chage the kind of modem... without success.
We have make some check on our telephone line...
But the problem occure in two different city...
And the line seem to be good.
In the same time we have notice an other PPP problem....
Problem with CD line of the PPP driver.
Brian@freebsd.org have make a good job on this problem.
The Cyclade work fine with TUN and PPPD.
But for finish, this is a very bigger problem.
The PPP hangup at random.
Here we use 2.X.X from long time. And we have this hangup problem from long time
also, but we alway say that we use a bugy Cyclade driver. with a bad CD operati
on.... Brian have recently fixe the problem.
But we have upgrade the other net last month.
From 1.1.5 to 2.2.2+comit before 2.2.5 alpha. + place the Brian stuff.
Just the day after the upgrade, our customer have start to complain about hangup
that ocure at random (5 min.. 6 houres....) at any time.
some time the random hangup at very short time, other time it's more long...
And the problem occure on cy0 and sio devices. And we have this problem here fro
m the 2.X.X on our net from one year ago in superposition of the CD problem.
That's why we have not upgrade the other net one year ago, in the same time of o
ur net.
I am not sur about my theory, but I suspect a deep problem in the kernel of the
2.X.X.
The last variable that I must isolat is the FreeBSD 2.X.X.
I try to replace the FBSD to a Linux Box. Just to be sure that the problem is no
t hardware. (line, modem, serial card, ram, CPU...) I will give to you more
feedback when my tests are done.
PS: if I check all the log, all the brodcast message.... every thing seem to
happen correctly. But at the customer side of the modem,
it's not an intentionnal customer hangup. I think the PPP received a SIG for han
gup the line. But this SIG not come from DTR.
(excuse me for my bad english... usualy I speak french!)
