Hello,
I'm a teacher in germany, so please ignore my "funny" english.
The german text follows below.
Ihr englisch ist besser als mein deutsch.
I have a SuSE 9.3 network in school with a server for NIS and /home
and yone room with 14 clients and one with 8. After clients update to 10.1
(actualized with smart) I'm having a big problem with ypserv/ypbind. On
every second machine the login manager shows none of the 600 user names when
the PCs are started for first time. A restart of X solves it.
On console nr 1 the boot screen shows "ypbind ....." instead of "ypbind ."
on the correct ones. I think, that this is the problem.
Is it possible to tell ypserv to creat a logfile?
Is it possible to tune up ypserv.
Would an update of the server to 10.1 be a solution?
Should I use 10.0?
I've no idea (yet) where to screw :-(.
There are only 14 clients, so the server should be fast enough (1,3 GHz,
2 GB RAM, 100MBit network, one unmanaged switch).
Any idea would be great !
On a server that does not anyone using the keyboard, there is frequently too little entropy for /dev/random to provide a random number for the password hashing. Under these conditions, /dev/random will block. On the other hand, /dev/urandom never blocks. If the entropy pool is low, it returns as good a random number as it can. The security is not as good, but it is probably good enough for your purposes. If this is the source of your delay, perform the following steps as root:
mv /dev/random /dev/random.save
ln -s /dev/urandom /dev/random
Later kernel versions seem not to block, but I cannot prove that.
Guten Tag,
Larry
