Greetings,
I have installed 'bochs' (to support a some legacy software) and need to
get networking working for it under ububtu (hoary).
It doesn't seem to be working 'out of the box' yet and I don't
understand why.
I'm following the documentation for bochs found here:
http://bochs.sourceforge.net/doc/docbook/user/config-tuntap.html
- The device '/dev/net/tun' is present.
crw-rw---- 1 root root 10, 200 2005-05-25 10:23 /dev/net/tun
- Bochs has an example config in ubuntu which looks for 'ethdev=/dev/net/tun0'
Is this correct?
ne2k: ioaddr=0x240, irq=9, mac=fe:fd:00:00:00:01, ethmod=tuntap,
ethdev=/dev/net/tun
I get the eror "Message: open failed on /dev/net/tun0: No such file
or directory"
Changing this to '/dev/net/tun' causes a different error
"open failed on /dev/net/tun: Invalid argument"
Investigating
- Looking at 'cat /proc/devices' shows 'character device 10' to be 'misc'
Is this correct?
# modprobe tun [this works! (what is this 'misc' thing?)]
Also...
