Why None Of These Programs Work On a VPS?
 

I'm trying to check my server's bandwidth usage in real time, installed the following programs but none worked so far.

Iptraf - No results even when using iptraf -u
Tcptrack - Error : pcap_loop: cooked-mode frame doesn't have room for sll header
Iftop - No results, everything 0b

Are there any programs that displays bandwidth usage in real time and actually works on VPSes? Or getting real time bandwidth usage on a VPS is simply impossible?

Thanks.

That's going to depend on what the interfaces represent themselves
as, I'll guess. Got shell? What's the result of
ifconfig
?

All the network interfaces are in the format "venet0:X", and below is the output of ifconfig :

So what happens when you try

(seeing as it's the one with the most traffic I'll assume it's what
your server talks on the big bad world)?

Yeah, It returned the following :

Guess there's no other way / workarounds expect getting a *real* dedicated box? :cry:

Dunno ... you may look at something like using iptables & the ulog
target to get your totals. Or check whether you can get the other
tools to play with that interface.
