We are using PingER, perfSONAR/NDT and PlanetLab landmarks for geolocation in TULIP. PlanetLab landmarks are manually updated with the help of perl script "insert_planetlab.pl" which is under the tulip directory /afs/slac.stanford.edu/package/pinger/tulip. This script loops over monthly active hosts in PlanetLab and inserts new one based on thier their availability. PingER nodes are updated with the help of automated script "create_sites-xml"(updated by trscrontab job running at 2:40am in pinger@pinger.slac.stanford.edu) which is located under TULIP directory.

- As it is evident there There are some mandatory fields mentioned in underline point are required to make the TULIP work.
- hostName,ipv4Addr,enabled (1 or 0) ,latitude,longitude,serviceInterfaceType(PingER/PlanetLab),tracerouteURL and tulipTier
- Additionally we can also give city,country,state,institution etc
. The list is given in the Required column of above table. - Process for making change in database
- Login to tulip database (username and password available in escrow -c iepm iepmacct Note: It works from pinger@pinger.slac.stanford.edu
| Code Block |
|---|
24cottrell@pinger:~>mysql -h mysql-node01 -P 3307 -u scs_tulip_u -p scs_tulip

The password is in escrow edit -c iepm iepmacct
or can be obtained by calling (assuming you have the right AFS privs): | Code Block |
|---|
require "/afs/slac/g/scs/net/pinger/bin/admin.pl";\\
my $wrdw = >pwd('tulip');
|
or by looking in /afs/slac/package/pinger/tulip/dbPwd/pws-tulip- Change the database to tulip by cmd
| Code Block |
|---|
mysql> use scs_tulip;
Database changed
|
- Now insert new records using the following sql cmd; in this instance we are using ipv4Addr = 141.22.213.35; generally ipv4Addr is the primary key but we can also use hostName as an identifier to disable landmarks
| Code Block |
|---|
insert into landmarks (hostName,ipv4Addr,enabled,latitude,longitude,serviceInterfaceType,tracerouteURL,
tulipTier,domain,pingURL,city,country,continent)
values ('mars.planetlab.haw-hamburg.de','141.22.213.35pinger.stanford.edu','171.66.6.39', 1 ,'37.4285','-122.178','PingER',
'http://pinger.stanford.edu/cgi-bin/traceroute.pl?','1','53.55stanford.edu',
'http://pinger.stanford.edu/cgi-bin/traceroute.pl?function=ping','Menlo Park','10United States','PlanetLab','141.22.213.35','1');North America');
|
- Or you can update an existing record, e.g.
| Code Block |
|---|
mysql> update landmarks set latitude='31.4190' where
hostname like '%www-wanmon.slac.stanford.edu%';
Query OK, 1 row affected (0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 0
|
- Update Sites.xml so that it can now use the updated landmarks using following cmd cmd Note: you might have to execute kinit and enter pinger password to get permission.
| Code Block |
|---|
/afs/slac/package/pinger/tulip/create_sites-xml.pl > ! /afs/slac/www/comp/net/wan-mon/tulip/sites.xml
