The delay isn't for it to retry; if the server's not there, the server's not there. It's for waiting to make sure that it's actually bound to a server; if the connection is timing out, telling it to try again isn't going to help. Or am I misunderstanding what you're saying? In a synchronized startup of a cluster (or any network) with some NIS server and some clients it may be reasonable for the slave to wait. This is the case I have in my installation. I have a cluster wich is turned on by just one power switch. The clients usually boot faster than the NIS server and they need to wait the additional few seconds. Also, even with the server running, the ypbind did not always succeed in connecting. Adding the forced config reread for ypbind seems to have fixed the problem for me. if you set ypbind to breadcast for an NIS server it will keep retrying every 30 seconds to bind to a new server. |
RH 6.0, upgraded from Mandrake 5.3 On system startup, in the file /etc/rc.d/init.d/ypbind called with argument 'start' the ypbind daemon only connects to the servrer, which is up at the moment the ypbind daemon is run. The delay loop added afterwards does not cause the ypbbind daemon to retry. Solution: (a) force running ypbind daemon to reread it's configuration and retry search for master, (b) increase the time between the retries or the number of retries, or both. Please, find below the appropriate excerpt from my corrected file. I expressely grant you the right to use this code section in your distribution without any obligation on your part. <skip> case "$1" in start) echo -n "Binding to the NIS domain...
