I cannot seem to set hostname
correctly on a home laptop,
which has a wireless connection
to a cable router.

How do I do it?

I have

hostname=""
ifconfig_wlan0="SYNCDHCP WPA"

in /etc/rc.conf

According to rc.conf(5):

                 If dhclient(8) is used to set the hostname via DHCP, this
                 variable should be set to an empty string.

But I still get empty hostname after boot:

# hostname

# 

# cat /var/db/dhclient.leases.wlan0
lease {
  interface "wlan0";
  fixed-address 192.168.1.104;
  next-server 192.168.1.1;
  option subnet-mask 255.255.255.0;
  option routers 192.168.1.1;
  option domain-name-servers 194.168.4.100,194.168.8.100;
  option host-name "00215c5068c3";
  option domain-name "cable.virginmedia.net";
  option dhcp-lease-time 86400;
  option dhcp-message-type 5;
  option dhcp-server-identifier 192.168.1.1;
  option dhcp-renewal-time 43200;
  option dhcp-rebinding-time 75600;
  renew 4 2018/3/22 07:21:14;
  rebind 4 2018/3/22 16:21:14;
  expire 4 2018/3/22 19:21:14;
}

# cat /etc/resolv.conf
# Generated by resolvconf
search cable.virginmedia.net
nameserver 194.168.4.100
nameserver 194.168.8.100


Does that help me?

I cannot run MPI programs without having a correct
hostname, i.e. I should be able to do ssh `hostname`.

What am I missing?

Thanks

Anton
