[DEV]"xcatd: install monitor" process(listening on ipv6 socket) will die on status update from node failed on reverse dns lookup #2459
Description
steps to reproduce:
- on a rhels7.3 mn with at least 1 nic with ipv6 enabled
# ip addr|grep inet6
inet6 ::1/128 scope host
inet6 fe80::9abe:94ff:fe00:c478/64 scope link
inet6 fe80::9abe:94ff:fe00:c47a/64 scope link
inet6 fe80::9abe:94ff:fe00:c47b/64 scope link
- install the package "perl-IO-Socket-INET6" and "perl-Socket6" , then restart xcatd
- make sure the xcatd processes are listening on ipv6 stack:
# netstat -nltp|grep -w "3001\|3002"
tcp6 0 0 :::3001 :::* LISTEN 90301/xcatd: SSL li
tcp6 0 0 :::3002 :::* LISTEN 90305/xcatd: instal
- then run "/xcatpost/updateflag.awk" from a node whose hostname can not be reverse lookup on
nslookup <ip>
/xcatpost/updateflag.awk fs4 3002 "installstatus booted"
- then the process "xcatd: install monitor" will be found died on the mn
ps aux|grep "xcatd: install monitor" |grep -v grep
