01/31/96 Information Needed to Study TCP/IP Problem SPECIAL NOTICES Information in this document is correct to the best of our knowledge at the time of this writing. Please send feedback by fax to "AIXServ Information" at (512) 823-4009. Please use this information with care. IBM will not be responsible for damages of any kind resulting from its use. The use of this information is the sole responsibility of the customer and depends on the customer's ability to eval- uate and integrate this information into the customer's operational environment. | ABOUT THIS DOCUMENT | This document describes how to collect TCP/IP information to | send to AIX support for problem determination. This docu- | ment applies to AIX 3.2 and 4.1. This document assumes that you are working with AIX Support under one of the service options. For information on the AIX Support Family and Program Services (IBM's base support for code-related problems), request these faxes from 1-800-IBM-4FAX: 1537 Overview of AIX Support 1760 Using Program Services 2464 The AIX Support Family Non U.S. Customers can requests documents by dialing (from a fax machine) 514-855-4FAX. STEPS Please follow these steps to gather information about your TCP/IP problem for AIX support. NOTE: Please be careful of the FILE NAMES and the REDI- RECTION (don't use ">" instead of ">>"). In the following steps, replace with your problem report or item number. 1. Run the following commands: mkdir /tmp/ netstat -ni > /tmp//netstat.out netstat -nr >> /tmp//netstat.out netstat -v >> /tmp//netstat.out netstat -m >>/tmp//netstat.out iptrace /tmp//iptrac.rawfile 2. Reproduce the problem. 3. After reproducing the problem, run the following com- mands: Information Needed to Study TCP/IP Problem 1 01/31/96 ps ax | grep iptrace # to obtain the PID of "iptrace" kill -9 echo "RESULTS................" >> /tmp//netstat.out netstat -i >> /tmp//netstat.out netstat -v >>/tmp//netstat.out netstat -m >>/tmp//netstat.out errpt -a > /tmp//errpt.out arp -a > /tmp//arp.out 4. In a README file, record what happened while the problem was being reproduced. Your description should include the following information: o Detail of which machines were used for client and server o How problem was reproduced 5. Choose one of the following commands to start the device driver trace. Be careful to use commas between the hook IDs (for example, "1cc,251,255"). To start a trace for a High Performance Ethernet device driver, run the following command: trace -a -j 1cd,251,255 To start a trace for an Integrated Ethernet device driver, run: trace -a -j 1cc,251,255 To start a trace for a Token Ring device driver, run trace -a -j 1ce,251,256 To start a trace for a FDDI device driver, run trace -a -j 262,263 6. Now, reproduce the problem again. 7. Then issue the following command to turn off the trace: trcstop 8. Now copy the raw trace file. For Ethernet: cp -p /usr/adm/ras/trcfile /tmp//entdd.trace For Token-Ring: cp -p /usr/adm/ras/trcfile /tmp//tokdd.trace 9. Now, compress and tar the whole directory. tar -cvf- | compress > .tar.Z Information Needed to Study TCP/IP Problem 2 01/31/96 10. tar the compressed tar file to diskette or tape: tar -cvf /dev/(device) .tar.Z 11. Label the media with the problem report or item number and the branch office number and the command used to place the data on the media. 12. Send the data to one of the following addresses: Standard or overnight mail: NOTE: Look at the "file Naming Convention" section of this document and name testcases accordingly. IBM Corp. / Zip 2900 / Bldg 42 Attn: AIX Testcase Dept. J66S 11400 Burnet Road Austin, TX 78758-3493 Extension 3-4050 Note: NO overnight delivery service delivers directly to bldg. 42, instead they are delivered to IBM Receiving. Please keep this in mind when choosing a delivery time. If you specify Saturday delivery you must first make special arrangements with an AIX Support specialist (1-800-225-5249 or 1-800-call-aix), otherwise there could be a delay of several days. IBM Internal (VM) REMINDER: If you have absolutely no other available elec- tronic method of sending a testcase, you can send it through VNET. This method only works for IBM internal customers. It is not automated, which could cause delays in testcase proc- essing. FTP IS THE PREFERRED METHOD FOR SENDING TESTCASES. The testcase should be combined into a single compressed tar archive and uploaded in BINARY format. Please name the file PPPPPBBB TARZBIN, where PPPPP is the PMR number and BBB is the branch office number (without the "b"). node = "AUSVMR" userid = "V3DEFECT" E-Mail Information Needed to Study TCP/IP Problem 3 01/31/96 +--- SERVICE USE AGREEMENT --------------------------------+ | | | International Business Machines Corporation | | Internet Testcase Delivery Service | | Service Use Agreement | | | | THIS IS A LEGAL AGREEMENT TO WHICH YOU ARE CONSENTING TO | | BE BOUND.

The allowable size of the testcase depends mostly on intermediate mail gateways. It is gener- ally not advisable to send tescases larger than approxi- mately 4MB via e-mail. Testcases sent via e-mail in the correct format are automatically processed, making them almost immediately available for analysis. See the "File Naming Convention" section of this document for more details. FTP Via Internet Sample file names for the tarred and compressed files: ad1000.tar.Z (item number.tar.Z) 1x234.001.tar.Z (problem_report_#.branch_office_#.tar.Z) 1x234.1234567.tar.Z (problem_report_#.customer_#.tar.Z) FTP it to our testcase repository: ftp 198.17.57.67 (or "ftp testcase.boulder.ibm.com") login: anonymous password: (e.g., "customer@wallyworld.com") bin (change to binary transfer mode) cd aix put 1x234.001.tar.Z (for example) ls -l quit FILE NAMING CONVENTION: NOTE: Testcases should be archived into a compressed tar archive using relative path names. If FTPing, Do not create a separate directory on the testcase server. Use of the following naming convention will allow our tools to automatically move the testcase to the proper directories and update the PMR to indicate that the testcase is avail- able. Failure to use this naming convention could cause delays in processing the testcase. If the testcase files cannot be associated with an existing PMR or XMENU item, they will be tagged as lost and eventu- ally deleted. Testcases associated with PMRs Information Needed to Study TCP/IP Problem 5 01/31/96 ppppp.bbb.ccc.tar.Z | | | | | | | | | Indicates that the archive is compressed. | | | | If you have the gzip command available, | | | | this will be .gz rather than .Z. | | | | | | | Indicates a tar archive. | | | | | The 3 character country code. | | (May be omitted if the country code is 000.) | | | The 3 character branch office number. | The 5 character PMR number. Testcases associated with XMENU items xxxxxx.tar.Z | | | | | Indicates that archive is compressed. | | If you have the gzip command available, | | this will be .gz rather than .Z. | | | Indicates a tar archive. | The XMENU item number. CREATING A COMPRESSED TAR ARCHIVE Testcases should be archived into a compressed tar archive using relative path names. The following is an example of how to create a compressed tar archive. o Place the testcase files into a separate directory using commands similar to those in the following example. In this example, we'll use a directory named /tmp/testcase. cd /tmp mkdir testcase cp file1 file2 file3 testcase o Execute one of the following commands to create the com- pressed tar archive. Using the gzip command (if avail- able), will generally produce a significantly smaller file. With the gzip command: tar -cf- testcase | gzip -9 >9x999.999.999.tar.gz Without the gzip command: tar -cf- testcase | compress >9x999.999.999.tar.Z Testcases should be archived into a compressed tar archive using relative path names. The following example will uuencode and send the compressed tar archive created in the previous section. You should substitute the correct filename when sending your testcase. uuencode 9x999.999.999.tar.gz 9x999.999.999.tar.gz | \ mail -s "AIX_Testcase:9x999.999.999.tar.gz" aasc@austin.ibm.com Information Needed to Study TCP/IP Problem 6 01/31/96 READER'S COMMENTS Please fax this form to (512) 823-4009, attention "AIXServ Informa- tion".
