PingER and the tracerouter server were installed at Daffodil University in Bangladesh.

• http://203.190.11.4/cgi-bin/traceroute.pl works for both reverse traceroute and pin servers.
• http://203.190.11.4/cgi-bin/ping_data.pl responds with the form, however:
  • The output has been modified to remove the debugging/help boxes at the top. See Difference in Daffodil and normal ping_data.pl form output
  • When one gathers data (e.g. by pushing Getdata!) one gets the response:

    #No data found in 0 lines of data between dates specified in /usr/local/share/pinger/data/ping-2013-09.txt. #Dates: 2013/9..2013/9. Epoch time searched from 1380240000-120 secs to 1380412740+120 secs #Results (6 lines) from /usr/bin/tail -20 /usr/local/share/pinger/data/ping-2013-09.txt are: #Pinging pinger.daffodilvarsity.edu.bd [203.190.11.4] with 32 bytes of data: #Reply from 203.190.11.4: bytes=32 time=12ms TTL=63 #Reply from 203.190.11.4: bytes=32 time=3ms TTL=63 #Reply from 203.190.11.4: bytes=32 time=8ms TTL=63 #Reply from 203.190.11.4: bytes=32 time=9ms TTL=63

To further investigate we were provided an account on 203.190.11.4.

We followed the information in http://www-iepm.slac.stanford.edu/pinger/faq.html#nodata

• The PingER directory is at: /usr/local/share/pinger/.

  [root@pinger ~]# cd /usr/local/share/pinger [root@pinger pinger]# ls -l total 140 -rw-r--r-- 1 root root 16844 Sep 1 12:20 beacons.txt drwxr-xr-x 2 root root 4096 Sep 14 16:52 data -rwxr-xr-x 1 root root 300 Sep 1 12:20 dnsV4Cmd.pl -rwxr-xr-x 1 root root 5385 Sep 1 12:20 installCron.pl -rw-r--r-- 1 root root 34443 Sep 1 12:20 pinger2.html -rw-r--r-- 1 root root 50442 Sep 1 12:20 pinger2.pl -rw-r--r-- 1 root root 314 Oct 1 00:30 pingerCronStat.stderr -rw-r--r-- 1 root root 518 Oct 1 00:30 pingerCronStat.stdout -rw-r--r-- 1 root root 1610 Oct 1 00:30 pinger.xml -rw-r--r-- 1 root root 2512 Sep 1 12:20 pinger.xsd

pinger.xml

• There was nothing in the <BeaconList></BeaconList> stanza. This is normally updated weekly by pinger2.pl accessing the beacon table at SLAC http://www-iepm.slac.stanford.edu/pinger/beacons.txt.
• <SrcName>pinger.slac.stanford.edu</SrcName> needs to be updated to <SrcName>203.190.11.4</SrcName>.
• Also the host needs to get a Domain name registration (e.g. pinger.daffodilvarsity.edu.bd>):w and that entered into the <Srcname>
• Looking at the processes running I see:

  [root@pinger pinger]# ps -efl | grep pinger 5 S avahi 6628 1 0 80 0 - 822 - Sep01 ? 00:00:41 avahi-daemon: running [pinger.local]

  and

  [root@pinger ~]# ps -efl | grep http 5 S apache 13111 16592 0 80 0 - 8046 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13112 16592 0 80 0 - 8112 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13113 16592 0 80 0 - 8079 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13114 16592 0 80 0 - 8112 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13115 16592 0 80 0 - 8079 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13116 16592 0 80 0 - 8112 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13117 16592 0 80 0 - 8079 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13120 16592 0 80 0 - 8112 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S apache 13121 16592 0 80 0 - 8079 - Sep29 ? 00:00:00 /usr/sbin/httpd 5 S root 16592 1 0 80 0 - 8046 - Sep14 ? 00:00:21 /usr/sbin/httpd

The crontab shows:

[root@pinger ~]# crontab -l
*/30 * * * * cd /usr/local/share/pinger; perl /usr/local/share/pinger/pinger2.pl > /usr/local/share/pinger/pingerCronStat.stdout 2> /usr/local/share/pinger/pingerCronStat.stderr

And the pinger2.pl version is the latest (2.0.6).

pingerCronStat.stdout log

pingerCronStat.stderr log

Can't exec "/usr/local/bin/lynx": No such file or directory at /usr/local/share/pinger/pinger2.pl line 518.
Use of uninitialized value $beacons in split at /usr/local/share/pinger/pinger2.pl line 520.
Use of uninitialized value $nline in concatenation (.) or string at /usr/local/share/pinger/pinger2.pl line 596.

Resolution

There is a lynx on the host. It is at /usr/bin/lynx. This needed to be entered in the pinger.xml file, i.e.

 <HttpGetBin>/usr/bin/lynx -source -dump %s</HttpGetBin>

In addition I verified that the locations of the dig, mail and ping were correctly entered in pinger.xml.

I looked at the latest entry in /usr/local/share/pinger/data/

[root@pinger pinger]# ls -l data/
total 32
-rw-r--r-- 1 root root 27480 Oct  1 03:54 ping-2013-09.txt

The update time and date were recent and there were >> 1000 bytes in the file so it looked promising. So I did a head command on the file:

[root@pinger ~]# head /usr/local/share/pinger/data/ping-2013-09.txt
