gethostbyname() always does DNS lookup when DISPLAY is set
hello,
i'm facing a really weird problem on my machine. when doing "telnet localhost"
my machine always does a DNS lookup even if
- host.conf: order hosts, bind
- nsswitch.conf: hosts: files dns
- localhost is defined in /etc/hosts
now, if i do 'unset DISPLAY' this behaviour goes magically away ...
- DISPLAY not set -> network not touched
- DISPLAY=:<displaynum> -> dns lookup made
- DISPLAY=<host>:<displaynum> -> network not touched
this looks extremely weird to me: dns does not have anything to do with X,
does it ? also, on the debian machine of a friend i cannot trigger this
behaviour, even with identical /etc/hosts, /etc/host.conf, /etc/
resolv.conf, /etc/nsswitch.conf
this is very annoying too, since when the network is down, starting KDE/gnome
apps takes ages (it takes as long as a DNS timeout)
another very weird thing: on my system, by default, libraries come from
/lib/tls, on my friends system they come from /lib. ld.so.conf is identical.
moving away /lib/tls has no effect on the dns lookup behaviour.
Someone knows what could be the origin of this problem ? and somebody knows
what /lib/tls is for ?
thanks,
greetings,
frank
