Tcpdump: verbose output suppressed, use -v or -vv for full protocol decode Set a filter to view network only for and from a specific IP address. Inet6 fe80::20c:29ff:fec1:c727/64 scope linkģ: ens38: mtu 1500 qdisc fq_codel state UP group default qlen 1000
$ ip address showġ: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 The following is an example of how the interface identified as eth0 could be permanently configured with a port speed of 1000Mb/s running in full duplex mode.Identify the network interface that you want to capture the network traffic packets. If an interface was assigned a static IP, it will be listed in one of the config files.Īdd calls to ethtool in this file: $cat /etc/network/interfaces. This directory will hold files with names that should match interface names you have configured in the netmanager GUI panel. Ubuntu used Network Manager by default to manage the configuration and dynamic use of network interfaces. iperf and iperf3 - see ESnets page on iperf3.Try this: cat /proc/net/snmp - lists snmp MIBs tracked by each networking layer.snmp - system to remotely monitor computing and networking systems.
ncat : concatenate and redirect sockets.nc, netcat : tool to setup sockets (tcp, udp).traceroute - finds the set of routers between two IP hosts.ipfw - interface to the Linux firewall, including NAT.editcap -F libpcap dump.pcapng dump.pcap.Issue editcap -F to list available formats.

To install editcap, install wireshark command line tools.Convert from Pcap-NG trace format (wireshark's default) to tcpdump pcap using editcap.tcptrace / xplot - analyzes tcpdump trace files.yum install wireshark-gnome (or remove gnome if just want command line tools).wireshark (need to install with apt-get).-X : dumps the data in hex and ascii format.-tt : puts timestamp in slightly more useful format.-nn : turns off dns lookups - in large traces this is recommended to reduce time to process.example sudo tcpdump -nn -tt -X -r mytrace.dmp > ace #translates the raw trace info to human readable format.For large traces, typically use 64 or 128 byrtes. The -s param says to capture up to 1500 bytes of each packet. #captures all icmp packets flowing in/out of eth0- saves in a binary file mytrace.dmp.example : sudo tcpdump -i eth0 -s 1500 'icmp' -w mytrace.dmp.netem: note that netem and htb will not work together!!!
