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/.

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:
and

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).

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:
