ATTCP - AIX Test TCP program

[Michael]

Q. What is ATTCP?

A. Another TCP Tester

Quick link: latest version is: aixtools.attcp.0.6.6.0.I
Wiki page: http://www.aixtools.net/index.php/attcp

ATTCP is a network exerciser and, especially, bandwidth measurement tool developed specifically for AIX (perhaps ATTCP also stands for AIX TTCP  and testing high-speed networks - e.g., 10GBit and faster.
Please post comments, feedback, requests, etc.. for ATTCP in this thread!

update: new version 14 April 2017

Dear

I download the attcp soft and  follow the installntion step for attcp soft,but when I execute the lslpp command,the result as follow:

# lslpp -l aixtools.attcp.rte
  Fileset                      Level  State      Description         
  ----------------------------------------------------------------------------
Path: /usr/lib/objrepos
  aixtools.attcp.rte         0.6.4.0  COMMITTED  1550 1214 1751

is different to your as bellow:
root@inlp02:[/home/root]lslpp -L aixtools.attcp.rte
  Fileset                      Level  State  Type  Description (Uninstaller)
  ----------------------------------------------------------------------------
  aixtools.attcp.rte         0.6.1.0    C     F    attcp 0.6.1.0 2014.May.26
                                                   13.27 CUT

i think the attcp soft can not to use,could you help to send attcp soft to me? thx...

Hi, Thanks for your interest. Helps me focus on where to improve.

The wiki page: http://www.aixtools.net/index.php/attcp

has 0.6.4.0 as the latest version, so your lslpp output is correct.

FYI the 'Description' the AIX builddate (1550 == 2015 week 50); followed by Date: 1214 == December 14, and the time 1751 is 5:51pm, or 17:51.

As too many people 'did not like that' I am changing it in newer packages.

hi,thanks for your kindly reply,but I can't execute the command and report errno=79,the detail information as bellow:

/opt/bin/speedto: performing a 10 second write
Usage: attcp -x [-options] [-h] host ## transmit (xmit)
       attcp -r [-options] [-c host] ## read from network
Common options:
        -x      source a pattern to network
        -r      read as datasink (discard) all data from network
        -c host "collect call": initiate connection with host then receive data
        -h host set hostname to connect with
        -l ##   length of bufs read from or written to network (default 8192)
        -n ##   number of source bufs written to network (default 20480, or 20k)
        -i ##   "interval": number of seconds to run the test: rather than # of buffers (see -n)
                using defaults only - 20k * 8k (or 160M) bytes is transferred per thread
        -t ##   number of threads (default is 1)
        -p ##   port number to send to or listen at (default 49149)
        -u      use UDP instead of TCP
        -d      don't buffer TCP writes (sets TCP_NODELAY socket option)
        -D      set SO_DEBUG socket option
        -s ##   set socket buffer size (if supported)
        -f X    format for rate: b,B = {bit,byte}; k,K = kilo{bit,byte};
                m,M = mega; g,G = giga; r,R = raw {bit,byte}
        -q      "quiet": only print the measured throughput, emit no other chatty output.
        -v[vvv] verbose: print more statistics
Options specific to -r:
        -B      process full blocks as specified by -l (concate reads until "blocksize" is reached
        -T      "touch": access each byte as it's read

Thanks for reporting this 'packaging' bug.

A easy way to check is to look in /etc/services, e.g.,

Code: [Select]

root@x069:[/mnt/tools]tail /etc/services
com-bardac-dw   48556/udp               # com-bardac-dw
#                               48557-48618             # Unassigned
iqobject                48619/tcp               # iqobject
iqobject                48619/udp               # iqobject
#                               48620-49150             # Unassigned
#                               49151                   # IANA Reserved
sco_printer             70000/tcp       sco_spooler     # For System V print IPC
sco_s5_port             70001/tcp       lpNet_s5_port   # For future use
ipsec_sk_master         1011/udp       
ipsec_sk_engine_s               4001/udp       

I know something is missing - namely the service names I use, as well as an entry in /etc/inetd.conf

The command is supposed to run automatically when it is installed, but it seems to be missing. I shall repackage asap - but here is the script - so you can run in asap:

Code: [Select]

then
        echo "ttcp     49149/tcp # ttcp port holder" >>/etc/services
        echo "ttcp     49149/udp # ttcp port holder" >>/etc/services

        echo "ttcpr     stream  tcp    nowait  nobody    /opt/bin/ttcpr     ttcpr" >>/etc/inetd.conf
fi

grep 49151 /etc/services
if [[ $? -ne 0 ]]
then
        echo "ttcps     49151/tcp # ttcp_sender faucet" >>/etc/services
        echo "ttcps     49151/udp # ttcp_sender faucet" >>/etc/services
        echo "ttcps     stream  tcp    nowait  nobody    /opt/bin/ttcps     ttcps" >>/etc/inetd.conf
fi
refresh -s inetd

And, I know to source of the problem - my first attempt to use autotools to manage the build process.

[Michael]

Repackaged as version 0.6.4.1 with the update to /etc/services and /etc/inetd.conf automated (also removed when uninstalled).

CHANGED the port numbers used to be both an unassigned number and below (tcp|udp)_ephemeral_low

See http://www.aixtools.net/index.php/attcp and/or http://download.aixtools.net/performance/aixtools.attcp.0.6.4.1.aix537.I

Made several updates this last week - at a customer who wanted to test their network throughput - so I was motivated.

The major changes: clean up the messages - but especially, better messages to syslog.

Syslog messages are now sent to "uucp.info" with ".info" being the standard messages. A few messages may also go to the .debug flow, but, for now, only .info is being used. Note: I choose uucp as that seems to be unused these days (and I am already logging httpd messages on user.* and mail.*, auth.*, daemon.* are also actively used by other applications.

[Michael]

Thanks for the message. Link is working now (my mistake).
