Hello, 1. I currently have a 128kbps cable link to the internet..and I'm sharing this connection with others. I've made the following script(for alocating bandwidth depending on the services used: browsing, squid, games like counter-strike, icmp, ssh), which unfortunately isn't working very well as the response times I'm getting upon pinging the server are almost the same I get without the htb script being loaded. Any ideas ? Here goes my script: where eth1 = the internal network card eth0 = the link to my ISP ipt="/sbin/iptables" tc="/sbin/tc" IF_EXT=eth0 IF_LOC=eth1 ######################################################################## ##### $tc qdisc del dev $IF_EXT root $tc qdisc add dev $IF_EXT handle 1: root htb default 99 r2q 1 $tc class add dev $IF_EXT parent 1: classid 1:1 htb rate 100kbit $tc class add dev $IF_EXT parent 1:1 classid 1:2 htb rate 20kbit ceil 20kbit prio 1 $tc class add dev $IF_EXT parent 1:1 classid 1:3 htb rate 60kbit ceil 90kbit prio 3 $tc class add dev $IF_EXT parent 1:1 classid 1:99 htb rate 20kbit ceil 90kbit prio 7 //I'm letting 1:2 use FIFO...for low-latency $tc qdisc add dev $IF_EXT parent 1:3 handle 30: sfq perturb 10 $tc qdisc add dev $IF_EXT parent 1:99 handle 990: sfq perturb 10 # ICMP $tc filter add dev $IF_EXT protocol ip prio 1 parent 1: u32 \ match ip protocol 1 0xff flowid 1:2 #Counter-strike $tc filter add dev $IF_EXT protocol ip prio 1 parent 1: u32 \ match ip dport 27015 0xffff flowid 1:3 $tc filter add dev $IF_EXT protocol ip prio 1 parent 1: u32 \ match ip dport 28015 0xffff flowid 1:3 # TOS Minimum Delay (ssh, NOT scp) in 1:10: $tc filter add dev $IF_EXT protocol ip prio 2 parent 1: u32 \ match ip tos 0x10 0xff flowid 1:3 ###################################### #acks $tc filter add dev $IF_EXT parent 1: protocol ip prio 2 u32 \ match ip protocol 6 0xff \ match u8 0x05 0x0f at 0 \ match u16 0x0000 0xffc0 at 2 \ match u8 0x10 0xff at 33 \ flowid 1:3 #dns query-uri $tc filter add dev $IF_EXT protocol ip prio 2 parent 1: u32 \ match ip dport 53 0xffff flowid 1:3 ############################################# # other services - web + irc $tc filter add dev $IF_EXT parent 1: protocol ip prio 2 u32 \ match ip dport 80 0xffff flowid 1:3 $tc filter add dev $IF_EXT parent 1: protocol ip prio 2 u32 \ match ip dport 6667 0xffff flowid 1:3 ############################################# # All others go to 1:99 $tc filter add dev $IF_EXT protocol ip prio 2 parent 1: u32 \ match ip dst 0.0.0.0/0 flowid 1:99 ######################################################################## ################## and for download I have the following: $tc qdisc del dev $IF_LOC root $tc qdisc add dev $IF_LOC handle 2: root htb default 99 r2q 1 $tc class add dev $IF_LOC parent 2: classid 2:1 htb rate 100kbit $tc class add dev $IF_LOC parent 2:1 classid 2:2 htb rate 70kbit ceil 90kbit prio 1 $tc class add dev $IF_LOC parent 2:1 classid 2:99 htb rate 30kbit ceil 90kbit prio 5 #PRIO FIFO...for 2:2 = low latency for counter-strike packets $tc qdisc add dev $IF_LOC parent 2:99 handle 299: sfq perturb 10 #Counter-strike $tc filter add dev $IF_LOC protocol ip prio 1 parent 2: u32 \ match ip dport 27005 0xffff flowid 2:2 #WEB $tc filter add dev $IF_LOC protocol ip prio 1 parent 2: u32 \ match ip sport 80 0xffff flowid 2:2 #SQUID $tc filter add dev $IF_LOC protocol ip prio 1 parent 2: u32 \ match ip sport 3128 0xffff flowid 2:2 # Restu $tc filter add dev $IF_LOC protocol ip prio 1 parent 2: u32 \ match ip dst 0.0.0.0/0 flowid 2:99 pinging the server without htb script loaded: [mihai@...mihai]$ ping -c 5 ip PING ip(ip) from .....: 56(84) bytes of data. 64 bytes from ip: icmp_seq=1 ttl=60 time=94.0 ms 64 bytes from ip: icmp_seq=2 ttl=60 time=41.3 ms 64 bytes from ip: icmp_seq=3 ttl=60 time=10.4 ms 64 bytes from ip: icmp_seq=4 ttl=60 time=25.5 ms 64 bytes from ip: icmp_seq=5 ttl=60 time=14.1 ms --- ip ping statistics --- 5 packets transmitted, 5 received, 0% loss, time 4036ms rtt min/avg/max/mdev = 10.454/37.105/94.057/30.443 ms pinging the server with htb script loaded: [mihai@.. mihai]$ ping -c 5 ip_addr PING ip(ip) from ...: 56(84) bytes of data. 64 bytes from ip: icmp_seq=1 ttl=60 time=31.1 ms 64 bytes from ip: icmp_seq=2 ttl=60 time=11.8 ms 64 bytes from ip: icmp_seq=3 ttl=60 time=38.5 ms 64 bytes from ip: icmp_seq=4 ttl=60 time=94.8 ms 64 bytes from ip: icmp_seq=5 ttl=60 time=31.5 ms --- ip ping statistics --- 5 packets transmitted, 5 received, 0% loss, time 4041ms rtt min/avg/max/mdev = 11.839/41.584/94.829/28.064 ms and tc -s qdisc shows: tc -s qdisc qdisc sfq 990: dev eth0 quantum 1514b perturb 10sec Sent 7574 bytes 75 pkts (dropped 0, overlimits 0) qdisc sfq 30: dev eth0 quantum 1514b perturb 10sec Sent 123614 bytes 1413 pkts (dropped 0, overlimits 0) qdisc htb 1: dev eth0 r2q 1 default 99 direct_packets_stat 0 Sent 149780 bytes 1678 pkts (dropped 87, overlimits 0) qdisc sfq 299: dev eth1 quantum 1514b perturb 10sec Sent 824005 bytes 1000 pkts (dropped 0, overlimits 0) backlog 3p qdisc htb 2: dev eth1 r2q 1 default 99 direct_packets_stat 2 Sent 1055635 bytes 1398 pkts (dropped 0, overlimits 2046) 2. I have the same problem with a htb script on an adsl connection (with the htb script I get ping response times of 80-90..without it I get 200-300 ms...but these response times aren't very stable..it's something like I'm getting 40 ms..then 100 ms..then 50 ms..) Sorry about the size of this message.
