| .Dt TORLOOKUP 1 | ||
| .Os | ||
| .Sh NAME | ||
| .Nm torlookup | ||
| .Nd tor exit node lookup for IP addresses | ||
| .Sh SYNOPSIS | ||
| .Nm | ||
| .Op Fl H Ar torDBfile | ||
| .Ar iplist | ||
| .Nm | ||
| .Fl d Ar directory | ||
| .Fl w Ar torDBfile | ||
| .Sh DESCRIPTION | ||
| .Nm | ||
| is a tool to lookup tor exit node information and their valid time intervals. | ||
| You need to create the nfdump specific lookup database first, before using | ||
| .Nm . | ||
| .Pp | ||
| .Nm | ||
| is also used to create the nfdump formatted lookup database file from a bunch of tor archive files. | ||
| There is no account required to download and build the nfdump tor database. | ||
| See the section below for the building instructions. | ||
| .Pp | ||
| .Nm | ||
| accepts a list of IP addresses either on the command line, separated by spaces | ||
| or on | ||
| .Ar stdin | ||
| line by line. The IP address on each line can be embedded in a string separated be | ||
| spaces on the left and right, therefore it can read the piped output from other tools. | ||
| .Pp | ||
| The options are as follows: | ||
| .Bl -tag -width Ds | ||
| .It Fl d Ar directory | ||
| Use the tor archive files in | ||
| .Ar directory | ||
| to build the binary lookup database file. With this argument | ||
| .Nm | ||
| creates a new binary lookup database file. | ||
| .It Fl w Ar torDBfile | ||
| Name of the new lookup database file. | ||
| .It Fl H Ar torDBfile | ||
| Use the binary torDBfile as lookup database for the tor exit node lookups. | ||
| .El | ||
| .Pp | ||
| To specify the tor lookup database | ||
| .Nm | ||
| searches at the following places: | ||
| .Bl -bullet -compact | ||
| .It | ||
| If the default | ||
| .Ar nfdump(1) | ||
| configuration file exists, it reads the tag | ||
| .Ar tordb.path | ||
| .It | ||
| If the environment variable | ||
| .Ar NFTORDB | ||
| is set, use this setting as lookup database. | ||
| .It | ||
| The command line argument | ||
| .Fl H | ||
| .El | ||
| If multiple locations are given, the environment variable | ||
| .Ar NFTORDB | ||
| overwrites the nfdump config file and the command line option | ||
| .Fl H | ||
| overwrites the environment variable | ||
| .Ar NFTORDB . | ||
| .Sh RETURN VALUES | ||
| .Nm | ||
| returns 0 on success and 255 otherwise. | ||
| .Sh ENVIRONMENT | ||
| .Nm | ||
| reads the environment variable | ||
| .Ar NFTORDB | ||
| .Sh EXAMPLES | ||
| The easiest way for creating or updating the binary lookup database is the use of the script | ||
| .Ar updateTorDB.sh | ||
| provided with all other nfdump files. The script takes a single integer argument. The integer argument | ||
| specifies for how many months back, you want to have the information available in the torDB. This means | ||
| you need to update the torDB and a regular basis, to have up to date information. Do not forget to | ||
| move the lookup database to the final location. | ||
| .El | ||
| .Pp | ||
| Lookup an IP with torlookup: | ||
| .Pp | ||
| .Dl % ./torlookup -H tordb_full.nf 178.218.144.18 | ||
| .Dl Node: 178.218.144.18, last published: 2024-07-31 11:53:12, intervals: 7 | ||
| .Dl 0 first: 2022-10-25 20:16:03, last: 2022-11-21 20:55:32 | ||
| .Dl 1 first: 2022-12-19 23:16:38, last: 2022-12-28 18:17:01 | ||
| .Dl 2 first: 2023-01-08 02:04:07, last: 2023-03-25 07:13:15 | ||
| .Dl 3 first: 2023-03-29 05:08:45, last: 2023-09-12 17:05:01 | ||
| .Dl 4 first: 2023-09-18 13:11:30, last: 2023-12-05 21:19:41 | ||
| .Dl 5 first: 2024-01-05 03:05:32, last: 2024-03-22 21:08:22 | ||
| .Dl 6 first: 2024-04-24 04:47:28, last: 2024-08-01 04:09:14 | ||
| .Pp | ||
| .Nm | ||
| returns the number of intervals, the IP was registered as exit node limited by first/last timestamps. | ||
| .Pp | ||
| Pipe the output of an nfdump statistic to torlookup for tor exit node verification: | ||
| .Dl % nfdump -r nfcapd.202408011200 -s ip | torlookup -H tordb_full.nf | ||
| .Pp | ||
| .Sh IMPLEMENTATION NOTES | ||
| If you use the tordb with | ||
| .Cm nfdump | ||
| to list flows and mark them as tor exit nodes, the IP address as well as | ||
| the flow start or flow end timestamp must fall into the approrpiate tor exit node interval. | ||
| In the pipe example above, torlookup does not care about timestamps. | ||
| .Pp | ||
| Use nfdump with the tordb: | ||
| .Dl % nfdump -H tordb.nf -r nfcapd.2024081200 -o tor | ||
| .Pp | ||
| .Sh SEE ALSO | ||
| .Ar nfdump | ||
| has already builtin lookup options to decorate the text output with tor information. See tags %stor, %dtor | ||
