CLI Network Troubleshooting Utilities
ThousandEyes provides a full suite of terminal based Network, DNS, and Voice utilities. These utilities come from the same code base that our Agents use to perform tests, and provide enhanced insight during troubleshooting.

Installing CLI Network Troubleshooting Utilities

The ThousandEyes Utilites Suite is bundled within the te-agent-utils package and is available for any host running a supported Linux distribution.
ThousandEyes repositories are automatically added to a host's package manager during Enterprise Agent installation. Hosts without an Enterprise Agent will require manual installation of a ThousandEyes software package repository.

Network Utilities

te-ping

A replacement for traditional ping, and can be run in a number of different application protocol modes. te-ping includes options to run in SACK, SYN, ICMP and VoIP modes, designed for use with different types of targets, and is consistent with the way that ThousandEyes measures end-to-end metrics in Network tests. Outputs include Loss, Latency and Jitter. Requires sudo permissions.

te-pathtrace

Runs a traceroute, using the same methods as are used by ThousandEyes to the endpoint. In addition to obtaining the IP addresses transited by each probe, our code shows quoted-ttl, response-ttl and MPLS label values for each probe. Since each agent test runs 3 probes (test attempts) to the target, if you want consistent results with that of the agent, run with option -P 3, to obtain three sets of trace data. Requires sudo permissions. Note in the example shown that the path to the same target IP diverges in two separate trace requests from the same target, at hop # 4 (shown in bold for emphasis). Using the Paris-traceroute algorithm (which is used by ThousandEyes in our Path Visualization view), this would show a path split, as in the image shown below.

te-bw

Designed as a replacement for iPerf, te-bw allows measurement of bandwidth, while having control of a single endpoint, and without the need to have exclusive access to the pipe. Use te-bw to measure estimated capacity, and available bandwidth on the pipe between the endpoint and target. Requires sudo permissions. When measuring bandwidth, te-bw shows the limiting bandwidth for UPSTREAM communication from the endpoint (ability of the endpoint to send data to the target), and DOWNSTREAM bandwidth from the target (ability for the target to send data to the endpoint). This is an important point for servers behind asymmetric links, such as ADSL.

Syntax and Options

IP address or DNS name of the target machine.

DNS Utilities

te-dns-trace

A special version of dig +trace which follows CNAME records across zones, in order to get to the requested record type. This is the same logic as is followed using the DNS Domain Trace test inside ThousandEyes. In addition, you'll receive more verbose feedback when the trace attempt is unsuccessful at retrieving records from an authoritative server, before the request fails over to a subsequent server. In the example shown below for www.healthcare.gov A, notice how the trace is followed from CNAME retrieved from the .gov zone, to Akamai, where the ultimate A record resides. A standard dig +trace request would stop at the line shown in bold. Does not require sudo permissions.

Syntax and Options

(sudo) te-dns-trace <domain> [type]
Parameter
Description
Required?
Default Value
domain

te-sigchase

Provides DNSSEC keychain validation (using bottom-up method) for the target record type. Requires that DNSSEC extensions are supported by routers used by the endpoint. See http://www.icann.org/en/groups/ssac/documents/sac-035-en.pdf for a list of devices which do not currently support required extensions for DNSSEC compatibility. Outputs of DNSSEC keychain validation will be the Data Chain, and Trust Tree responses for the validation request, similar to that which is shown in the output of DNSSEC tests in ThousandEyes. Does not require sudo permissions.

Syntax and Options

(sudo) te-sigchase <domain> [type] [key-file]
Parameter
Description
Required?
Default Value
domain
domain name to validate
Y
n/a
type
record type to validate
N
A
key-file
key file used for validation of root server signatures
N
A key file is provided and maintained with the te-agent-utils package. To view the content of the file, look at /var/lib/te-agent-utils/dns-rootserver.key

Voice Utilities

te-rtp

Designed to initiate an instant voice call to a VoIP server. It includes options to choose different Differentiated Services Code Point (DSCP) and codec values. Voice packets are encapsulated by a Real Time Transport Protocol (RTP) header, followed by further encapsulation through the transport layer protocol UDP and then sent using IP

Syntax and Options

(sudo) te-rtp [options] <target-ip>
Parameter
Description
target-ip
IP address of the VoIP server.
Option (short)
Option (long)
Description
Default Value
-h
--help
displays usage instructions
n/a
--source-port
source port to be used for the test
<random value>
-p
--port
destination port for the probe
5000
-P
--paths
# of paths to trace (in parallel)
1
-i
--interface
interface name to use for the test (use in conjunction with --source-ip option)
any
-s
--source-ip
source IP address ( use in conjunction with --interface option)
n/a
--dscp
DSCP value to be used for the voice call
0 = best effort
--codec
Audio codec value used for the VoIP call, 0=G.711, 1=G.722_24, 2=G.722_32
0 = G.711
-d
--stream-duration
To run the voice test call for desired time in seconds. For each 5 seconds, 50 packets are sent to the server
5 seconds
-o
--clock-offset
clock offset with the server
0
-v
--verbose
verbosity of the test; short command accepts -v (verbose) or -vv (very verbose), -vvv (very very verbose)
n/a

te-server

Designed to open up a port on the local machine to allow communication with the VoIP client. The desired server port should be configured to accept UDP connections inbound. It is always the machine running the te-voipserver utility that logs the probe statistics.

Syntax and Options

(sudo) te-server [options] <local-port>
Parameter
Description
local-port
Port on which the sever listens for incoming VoIP connections (UDP traffic)
Option (short)
Option (long)
Description
Default Value
-h
--help
displays usage instructions
n/a
--stunner-host
host in which to reach the STUNNER server
--stunner-port
port in which to reach the STUNNER server
-6
--ipv6
use IPv6 instead of IPv4
n/a
-j
--jitter
the size of the de-jitter buffer
0.1000000001 secs
--check-nat
whether to check if the NAT allows hole punching (only valid when using --stunner-host)
1
--agent-id
the agent id to use when connecting and authenticating to the STUNNER server
0
-v
--verbose
verbosity of the test; short command accepts -v (verbose) or -vv (very verbose), -vvv (very very verbose)
n/a
