Thank you. I agree that the first domainname should be used if none is set. Fixed in - Rawhide: ypbind-1_31-6_fc14 - Fedora 13: ypbind-1_31-4_fc13 Karel, thanks for the fix, works fine.
Suggested optimization of reducing these four processes from getting forked off:
NISDOMAIN=`grep "domain" /etc/yp.conf | grep -v ^# | \
awk '{print $2}' | head -1`
down to a single awk:
NISDOMAIN=`awk '/^[^#]/ { if ($1 == "domain") {print $2; exit} }' /etc/yp.conf`
Sorry to not offer this up earlier. I'll close this bug.
reopening, can we use the more effective syntax, pretty please? I strongly agree, and I believe we could remove the comment line check too, since the $1 comparison will never match a comment line anyway:
NISDOMAIN=`awk '{ if ($1 == "domain") {print $2; exit} }' /etc/yp.conf`
Either way, still a nice reduction from 4 fork/exec calls down to 1. Optimal.

Created attachment 421877 [details] change ypbind init script to call domainname only on first domainname listed in yp.conf We have multiple NIS servers that dhcclient populates for us in /etc/yp.conf. When ypbind starts, if domainname is not set, it awk's out the 'domain <domainname>' lines from yp.conf then calls "domainname" with the [potentially numerous] domains. As of Fedora 13, domainname will not run with multiple domains on the command line, thus ypbind fails to start. Boot messages (replacing real domainname with OurNISDomain): Setting NIS domain: domain is 'OurNISDomain OurNISDomain OurNISDomain OurNISDomain OurNISDomain OurNISDomain OurNISDomain' Usage: hostname [-v] [-b] {hostname|-F file} set host name (from file) hostname [-v] [-d|-f|-s|-a|-i|-y|-A|-I] display formatted name hostname [-v] display host name {yp,nis,}domainname [-v] {nisdomain|-F file} set NIS domain name (from file) {yp,nis,}domainname [-v] display NIS domain name dnsdomainname [-v] display dns domain name hostname -V|--version|-h|--help print info and exit Program name: {yp,nis,}domainname=hostname -y dnsdomainname=hostname -d Program options: -s, --short short host name -a, --alias alias names -i, --ip-address addresses for the host name -I, --all-ip-addresses all addresses for the host -f, --fqdn, --long long host name (FQDN) -A, --all-fqdns all long host names (FQDNs) -d, --domain DNS domain name -y, --yp, --nis NIS/YP domain name -b, --boot set default hostname if none available -F, --file read host name or NIS domain name from given file Description: This command can get or set the host name or the NIS domain name. You can also get the DNS domain or the FQDN (fully qualified domain name). Unless you are using bind or NIS for host lookups you can change the FQDN (Fully Qualified Domain Name) and the DNS domain name (which is part of the FQDN) in the /etc/hosts file. [FAILED] Starting NIS service: domainname not set - aborting. [FAILED] Suggested fix: take the first domainname in yp.conf and use only that. Works for me. Of course, if domainname is *suppose* to take multiple NIS domainnames, then this bug should be shifted over to net-tools.
