 |
|
Well, I decided to use network shaping to keep my download from getting choked by my upload rate, got my script written up real nice - but ran into a snag. I don't seem to have an eth0 node. I'm using dhcp, and the funny thing is that I'm getting network i/o.
dmesg |grep -i eth
| Code: | 8139too Fast Ethernet driver 0.9.27
eth0: RealTek RTL8139 at 0xd000, 00:e0:18:43:e5:df, IRQ 21
eth0: Identified 8139 chip type 'RTL-8100'
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
|
cat /proc/pci | grep -i eth
| Code: | | Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 16) |
find /dev/ -iname '*eth*' returns nothing though, and after running my shaping script watch tc -s class show eth0 says something like "what is eth0". Anybody know what could be happening here? |

eth0 is not a /dev node - so ?
It never is.
What happens when you run just tc ?

Here's my script:
| Code: | tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 20
tc class add dev eth0 parent 1: classid 1:1 htb rate 340Kbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 40Kbit ceil 340Kbit cburst 1752b prio 1
tc class add dev eth0 parent 1:1 classid 1:20 htb rate 300Kbit ceil 340Kbit cburst 1675b prio 2
tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 10
tc filter add dev eth0 parent 1: protocol ip u32 match ip sport 80 0xffff flowid 1:10
tc filter add dev eth0 parent 1: protocol ip u32 match ip sport 6969 0xffff flowid 1:10 |
And here's the output of
watch tc -s class show eth0
| Code: | What is "eth0"? Try "tc class help".
What is "eth0"? Try "tc class help".
What is "eth0"? Try "tc class help".
What is "eth0"? Try "tc class help".

When this script runs, my traffic still gets queued on the modem even though I have a higher upload rate than my max rate and ceil. Most likely because it cannot resolve eth0. |
