DNS Not working after TC_Install to USB

Hi There,

I wonder if someone can assist...  I'm new to TC, but know my way around RHEL and Ubuntu, so not a total noob :-)

Running TC in a virtualbox guest with an 8Gb virtual USB drive inserted.

Basically, I boot from CorePlus CD, choose (for example) the fluxbox option.  Go to TC_Install and follow the instructions.  The only changes I make really are adding "kmap=qwerty/uk vga=789" to the bootvars.  I choose to install everything except the Wireless networking bumpf, as I don't need that.

Upon then booting from the USB, APPs will not work, reporting "Error, check network, mirror or writable extension directory"

A bit of digging shows that DNS lookups are failing, and APPs is throwing "wget: bad address ftp.vim.org"

Note that DNS and installing apps when booting from coreplus CD works fine.

Also networking is up and running.  I can ping my server, SSH, and I can bring up web pages in chromium using the IP address instead of FQDN


I'm guessing there's something not working in the DHCPClient area, but I've no idea where to start looking, and I've been at this for hours now, bed is calling.

Could anyone please provide me with a little nudge in the right direction?

Many Thanks,

(P.S  Holy crap these captchas are hard to read!)

Use bridge mode, not NAT.  Then DHCP and DNS from your router will work.

You don't say if you're still running in vbox, or if the usb install is on real hw but the cd was in vbox?

Unfortunately that isn't possible due to restrictions on my work network.  However I doubt this is the problem, as it all works perfectly when booting from the TCPlus CD, it only fails after installing to the virtual USB.

Everything is virtual, including the USB stick (VDI attached as removable solid state device to USB controller)

Update - The problem appears to be related to there being multiple network interfaces...  eth0 is NAT and eth1 is Host Only.

It seems that after install, the DHCP derived DNS setting from eth1 (Which is blank) is overriding the setting received from DHCP on eth0.

If I disable the second interface then it works as expected.

I'm thinking this is probably a bug?

Why would you configure 2 virtual network interfaces in a VM?
