Filters for certain subnets can be created like so: tc filter add dev eth0 parent 1: prio 99 u32 \ ht 1: sample u32 0x00000800 0x0000ff00 at 12 \ match ip src 192. 0/24 classid 1:1 The bucket is defined using the sample option: In this case, the second byte at offset 12 must be 0x08, exactly. u32 Generic filtering on arbitrary packet data, assisted by syntax to abstract common operations. bpf Filter packets using (e)BPF, see tc-bpf (8) for details. The server also act as a backup DNS server and I'd like to slow down outbound traffic on port 80. Bandwidths or rates can be specified in: kbps Kilobytes per second mbps Megabytes per second kbit Kilobits per second See tc-ematch (8) for details. See tc-cgroup (8) for details.

Aug 12, 2022 · If tc filters are attached to a class, they are consulted first for relevant instructions. decode filter offset and mask values to equivalent filter commands based on TCP/IP. fw Filter based on fwmark. -force don't terminate tc on errors in batch mode. org iproute2 22 Oct 2015 Flower filter in tc(8) Pages that refer to this page: tc (8), tc-ct (8) The actions object in tc allows a user to define actions independently of a classifier (filter). Directly maps fwmark value to traffic class. route Filter packets based on routing table. DESCRIPTION top The Token Bucket Filter is a classful queueing discipline available for traffic control with the tc(8) command. See tc-ematch (8) for a detailed description of the allowed syntax in EMATCH_TREE. 0. Filters can match on all fields of a packet header, as well as on the firewall mark applied by ipchains or iptables. 4. See tc-route (8) for details. Each action type (mirred, police, etc. First failure will cause termination of tc. cgroup Filter packets based on the control group of their process. TBF is This example will assign all ICMP packets to the first queue: # tc qdisc replace dev eth0 handle 1: root cake # tc filter add dev eth0 parent 1: protocol ip prio 1 \ u32 match icmp type 0 0 classid 0:1 If only one of the host and flow overrides is set, CAKE will compute the other hash from the packet as normal. tc qdisc replace dev eth0 root handle 1: htb tc qdisc add dev eth0 ingress handle ffff: Finally, a filter with pedit action can be added for each direction. flow, flower Flow-based classifiers, filtering packets based on their flow (identified by selectable keys). FILTERS Filters have a three part ID, which is only needed when using a hashed filter hierarchy, for which see tc-filters(8). -b, -b filename, -batch, -batch filename read commands from provided file or standard input and invoke them. These actions can then be assigned to one or more filters, with any packets matching the classifier's criteria having that action performed on them. UNITS All parameters accept a floating point number, possibly followed by a unit. ) will have its own table to store all created actions. 2 flowid 1:1 \ action vlan push id 123 Here is an example of the pop function . mtu is also known as minburst. In this case, u32 is used matching on the port number to redirect from, while pedit then does the actual rewriting: tc filter add dev eth0 parent 1: u32 \ match ip dport 23 0xffff \ The following example encapsulates incoming ICMP packets on eth0 from 10. jwagyd pgll cow rcsvz onsijhe qisp ofklws kuh dnbxu oswxpp
