+In Fedora we use

+\fBypbind\fR

+daemon is prepared to answer. There is a test script /usr/libexec/ypbind-post-waitbind used in

+\fBypbind.service\fR,

+that waits for

+\fBypbind\fR

+daemon to be fully connected to NIS server and waits by default up to 45s. Sometimes this is not enough, because network set up can take longer than 45s during boot, so starting

+\fBypbind.service\fR

+fails. User can increase the

+\fBtimeout\fR

+by setting an environment variable

+\fBNISTIMEOUT\fR

+in /etc/sysconfig/ypbind. For example NISTIMEOUT=180 means ypbind will wait up to 180 seconds for binding to a NIS server.

+Another option is to enable NetworkManager-wait-online.service, which will make

+\fBypbind\fR

+.PP

+In case something needs to be changed in the

+\fBypbind.service\fR,

+it is adviced not to change the

+\fBypbind.service\fR

+directly, but rather to create a new file under /etc/systemd/system/ypbind.service.d/\&, i.e. if we need to start

+\fBypbind\fR

+before service foo.service, we can create file /etc/systemd/system/ypbind.service.d/wait-foo.conf with the following content:

+If you need to pass other arguments to

+daemon withing systemd unit file, you can set these arguments as

+\fBOTHER_YPBIND_OPTS\fR

+environment variable in /etc/sysconfig/ypbind. For example in order to set a fixed port ypbind should run on, you can specify OTHER_YPBIND_OPTS="-p 876" in /etc/sysconfig/ypbind\&.
