This directory contains a dump of the mysql DB with traceroutes, the file is called sqldump.gz. A second file (sqldump_IPv6.gz) contains the traceroutes for IPv6. These files are created by doing: $ mysqldump -u ttmuser --opt TTM | gzip -c > sqldump.0.gz $ mysqldump -u ttmuser --opt TTM_IPv6 | gzip -c > sqldump_IPv6.gz The files are updated once a day, between 21:00 and 22:00 GMT. During this period, they may disappear for a few minutes. The files can be restored into a mysql DB by doing: $ gzip -dc sqldump.gz | mysql import As of May 11, 2004, the IPv4 file is split into pieces of (at most) 250 Mb, the files are named sqldump.0.aa, sqldump.0.ab, etc. To import those into a mysql DB, do: $ cat sqldump.0.* | gzip -d | mysql TTM Note that one has to get the entire set of files every time.
