Description Aleksey Nogin 2002-09-25 01:23:12 UTC

In /etc/nsswitch.conf I have the default

hosts:      files nisplus dns

However, for hosts that have both DNS and /etc/hosts entry, the DNS entry is
used and only in a host is not known to DNS, the /etc/hosts entry will be used.

This might have secutiry implications is certain cases, so setting "Severity:
security".

Can you attach a strace output of such program plus what exactly do you have
in /etc/hosts?
Works just fine for me.

Comment 2 Aleksey Nogin 2003-01-06 10:22:50 UTC

I no longer can reproduce it, sorry.
