Bug ID: 236014
Summary: w -nn doesn't resolve hostname to ipv6 numeric if host
has v4 and v6 entry.
Product: Base System
Version: 12.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
When trying to display numeric entries for hosts using 'w' it will not resolve
ipv6 related hostnames to ipv6 nuemric entries if the host has the same
hostname entry with resolution on v4 and v6.
For example:
nistor@spike:~> w -n nistor
10:50PM up 43 days, 21:36, 24 users, load averages: 0.31, 0.27, 0.21
USER TTY FROM LOGIN@ IDLE WHAT
nistor pts/19 cpexxxxxxxxxxxx-cmxxxxxxxxxxxx.cpe.net.c Sat02PM 2
-tcsh (tcsh)
nistor pts/32 v6host.domain.com 10:47PM 2
-tcsh (tcsh)
whereas:
nistor@spike:~> w -nn nistor
10:50PM up 43 days, 21:36, 24 users, load averages: 0.31, 0.27, 0.21
USER TTY FROM LOGIN@ IDLE WHAT
nistor pts/19 99.230.xxx.xxx Sat02PM 3
-tcsh (tcsh)
nistor pts/32 v6host.domain.com 10:47PM 3
-tcsh (tcsh)
If the host is an ipv6 host with no ipv4 resolution to it then the display
works fine:
nistor@spike:~> w david
10:55PM up 43 days, 21:41, 24 users, load averages: 0.31, 0.23, 0.19
USER TTY FROM LOGIN@ IDLE WHAT
david pts/12 r2.ip6.domain.com 22Jan19 9:12
-/bin/tcsh
nistor@spike:~> w -n david
10:55PM up 43 days, 21:41, 24 users, load averages: 0.31, 0.23, 0.19
USER TTY FROM LOGIN@ IDLE WHAT
david pts/5 2001:XXX:yyyy:f000::2 22Jan19 28days
