What do you have in your /etc/hosts file?

127.0.0.1 tecwin-udp tecwin-udp
#127.0.0.1 localhost.localdomain local host

Hey, what are you doing? you should not change the loopback device datas. thay have system uses. if you realy want to assign some names to it add it as an alias to the /etc/hosts file. NEVER comment the default settings of your loopback device!

if you have a network card you can set hostname and ip for that. this will be more safe!!!!
