RRDPIT

"rrpdit" is a small little tool that can be pointed at a directory on your system, and produce RPKI RRDP (RFC 8182) notification, snapshot, and delta files. You will need to use an http server of your preferred flavour to deliver these files to the world.

Changelog

Release 0.0.2

Ignore hidden files in the source directory. I.e. exclude any and all files and folders starting with a '.' character.

Release 0.0.1

Initial release.

Installing rrdpit

Assuming you have rsync and the C toolchain but not yet Rust, here’s how you get rust installed.

curl https://sh.rustup.rs -sSf | sh
source ~/.cargo/env

If you have an old version of rust installed you may have to update it.

rustup update

To install 'rrdpit' under your user's home directory, use this:

git clone git@github.com:NLnetLabs/rrdpit.git
cd rrdpit
cargo install

If you have an older version of rrdpit installed, you can update via

cargo install -f

Using rrdpit

You can ask rrdpit for help.

rrdpit --help
rrdpit 0.0.2
Dist to RPKI RRDP

USAGE:
    rrdpit --https <uri> --rsync <uri> --source <dir> --target <dir> [clean]

FLAGS:
        --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -h, --https <uri>     base rrdp uri
    -r, --rsync <uri>     base rsync uri
    -s, --source <dir>    source directory
    -t, --target <dir>    target directory

ARGS:
    <clean>    Clean up target dir (handle with care!)

Note that 'clean' is optional. If used rrdpit will try to clean out the target dir, i.e. it will remove unused session id dirs, and unused version directories for delta files which are no longer referenced.

Use this option with care. You do NOT want to use this and accidentally use a system directory for the --target option. Especially if you run this as root, which would be ill-advised as well.

Examples

Sync the entire ARIN RPKI repository:


$ mkdir -p tmp/arin
$ cd tmp/arin/
$ mkdir source
$ rsync -zarvh rsync://rpki.arin.net/repository ./source/
receiving file list ... done
./
arin-rpki-ta.cer
arin-rpki-ta/
arin-rpki-ta/5e4a23ea-e80a-403e-b08c-2171da2157d3.cer
arin-rpki-ta/arin-rpki-ta.crl
arin-rpki-ta/arin-rpki-ta.mft
arin-rpki-ta/5e4a23ea-e80a-403e-b08c-2171da2157d3/
.....
.....

sent 158.78K bytes  received 11.08M bytes  976.85K bytes/sec
total size is 14.25M  speedup is 1.27

Now create RRDP files in a target dir:

$ mkdir target
$ time rrdpit --https https://rpki.arin.net/rrdp/ \
              --rsync rsync://rpki.arin.net/repository/ \
              --source ./source/ \
              --target ./target/

real  0m0.848s
user  0m0.385s
sys   0m0.258s

Check that all expected files are there, or well, at least the number:

$ find ./source/ -type f | wc -l
    7031

$ grep uri ./target/8e142e20-236c-4694-8430-b05693fab150/1/snapshot.xml | wc -l
    7031

(note that that uuid is a randomly generated session id, used when the target dir is empty)

$ rm source/arin-rpki-ta.cer 
$ time rrdpit --https https://rpki.arin.net/rrdp/ \
              --rsync rsync://rpki.arin.net/repository/ \
              --source ./source/ \
              --target ./target/

$ cat ./target/notification.xml

$ cat ./target/8e142e20-236c-4694-8430-b05693fab150/2/delta.xml

</delta>

Note that if you sync again, and there are no changes in the source dir, no deltas will be written:

$ time rrdpit --https https://rpki.arin.net/rrdp/ \
              --rsync rsync://rpki.arin.net/repository/ \
              --source ./source/ \
              --target ./target/

$ find target

target/8e142e20-236c-4694-8430-b05693fab150/2/delta.xml
target/notification.xml

rrdpit will also perform some sanity checks on the existing RRDP files, and if it finds an issue it will use a new session:

$ find target -type f
target/8e142e20-236c-4694-8430-b05693fab150/1/snapshot.xml
target/8e142e20-236c-4694-8430-b05693fab150/2/snapshot.xml
target/8e142e20-236c-4694-8430-b05693fab150/2/delta.xml
target/notification.xml

$ echo "corrupt" > target//8e142e20-236c-4694-8430-b05693fab150/2/delta.xml


$ rrdpit --https https://rpki.arin.net/rrdp/ \
         --rsync rsync://rpki.arin.net/repository/ \
         --source ./source/ \
         --target ./target/
         
$ find target -type f
target/07cfc1ce-e7d9-4bec-8a70-9feb76778700/1/snapshot.xml
target/8e142e20-236c-4694-8430-b05693fab150/1/snapshot.xml
target/8e142e20-236c-4694-8430-b05693fab150/2/snapshot.xml
target/8e142e20-236c-4694-8430-b05693fab150/2/delta.xml
target/notification.xml

Optionally you can let rrdpit clean up old files as well:

$ rrdpit --https https://rpki.arin.net/rrdp/ \
         --rsync rsync://rpki.arin.net/repository/ \
         --source ./source/ \
         --target ./target/ \
         clean

$ find target -type f
target/07cfc1ce-e7d9-4bec-8a70-9feb76778700/1/snapshot.xml
target/notification.xml

Future

This code can possibly use more testing. And some things can be cleaned up. However, it seems to work well from the testing we have done.

Of course you can create issues, but given that our main effort is directed at Krill for the moment, which includes its own RRDP server, we cannot guarantee that issues will get a high priority. Pull requests may get more mileage ;)
