FreeBSD 5.3-STABLE #0: Mon Jan 31 04:37:33 MST 2005
xorg-6.8.1
xfce-4.2.0
installed from ports w/ gcc version 3.4.2 [FreeBSD] 20040728
Hi:
I notice that if I start xfce and then dial out using ppp, then it
takes quite a while for an Xterm to open. I did a netstat -n -f inet,
while I was waiting for the Xtrem to open and I saw this:
Active Internet connections
Proto Recv-Q Send-Q Local Address Foreign Address (state)
udp4 0 0 12.73.168.202.53478 12.102.240.2.53
I then did a sockstat -4 and I see this:
$ sockstat -4
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
xfce xfce4-sess 1011 15 udp4 12.73.173.233:62336 12.102.240.2:53
root syslogd 273 6 udp4 *:514 *:*
So it looks like xfce4-session is trying to find a domain name server?
I say that because /etc/services says that port 53 is for DNS.
I then looked in the code for xfce4-session-4.2.0/xfce4-session and
saw a progam entitled xfsm-dns.c which had this in it:
void
xfsm_dns_check (void)
<SNIP>
My question is why should a desktop have to check for a dns ? I may
have misidentified the problem. However I am curious as to why it
takes almost 2 minutes for the Xterm to open., when I am dialed out on
a modem.
NOTE: If I first dial out form a shell account (I am using useralnd
ppp) and then login again and start X, the xterms open quickly. The
slow Xterm opening only happens if I do startx first and then run
userland ppp.
Kind regards,
Jon
