Public bug reported:
Description:
When the user is doing "ping -f myhostname.tld", ping does a ipaddr->hostname
request at EACH packet. Which is quite a lot when used with a -f option.
Moreover it is quite useless as when used with -f, ping doesnt display the
result of the ipaddr->hostname, but only a single dot per packet.
- I discovered this when implementing a nss plugin (/etc/nsswitch.conf kindof
stuff).
- I dunno the actual impact of this, just seems like very inefficient.
- But if the nss plugin doesn't have an request cache, this will become quite
a
denial of service for this service
