Ubuntu: networking tip

But when i tried to ping some other machine, this didn’t work 🙁 I checked /var/log/messages and the onboard Broadcom Interface showed up as eth1, but i was not able to start it. When i ran $ sudo /etc/init.d/networking restart i got some error messages like: SIOCSIFADDR: No such device eth1 eth1: ERROR while getting interface flags: No such device No clue what went wrong, i googled a lot and finally i stumbled upon this forum entry: Then i ran: $ ifconfig -a and got a list with my network interfaces and more importantly with it’s MAC address.

Ubuntu Server insecurity?

i just found out that my Ubuntu Server 6.10 has login shells for almost all users set in the /etc/passwd file! That’s a very bad idea because this maybe enabled someone to install “Data Cha0s Back Backdoor” on my machine 🙁 I checked this with 2 other fresh Ubuntu Server 6.10 installations and both also had the login shells for users like daemon, mail, www-data and so on. Especially www-data should not have a chance to create a shell in my opinion!
