Remote Commands Over SSH

 

Your rsync.net account is a unix account, and any tool that runs over SSH or SFTP will work.

You cannot log in directly, though - there is no interactive session.

However, you can run a large number of unix commands (like find, rm, cp, mv, etc.) over SSH - like this:

 

ssh user@rsync.net rm -rf your/file

or:

ssh user@rsync.net md5 some/file

 

Note - if you really want to work interactively, you can always mount your rsync.net filesystem locally, using sshfs.

 

Exploring Space Usage

 

If you just want to see how much space your account uses, the 'quota' command is by far the best choice:

ssh user@rsync.net quota

 

You can use the 'du' command to inspect the space usage of particular directories within your account:

ssh user@rsync.net du -Ahd2 some/directory

 

 

Checksum Commands

 

Your rsync.net filesystem has access to the following checksum commands: md5, sha1, sha256 and rmd160

 

Remote checksums are run in this manner:

ssh user@rsync.net md5 some/file

 

Pipelining Through 'dd' (Database Dumps)

 

pg_dump -U postgres db | ssh user@rsync.net "dd of=db_dump"

 

mysqldump -u mysql db | ssh user@rsync.net "dd of=db_dump"

 

echo .dump | sqlite3 db | ssh user@rsync.net "dd of=db_dump"

 

git

 

You can run the git command in our environment to do things like this:

ssh user@rsync.net "git clone git://github.com/freebsd/freebsd.git freebsd"

 

Backup Tools

 

attic, borg, rclone, unison and rdiff-backup are installed (on our server side).

You would most likely call these commands by running these tools locally and connecting to rsync.net with them.

 

Miscellaneous Unix Commands

 

The other remote commands that can be used over ssh are: 

cat
dd
echo
test
tree
tail
cp (GNU)
ls
mkdir
pwd
chmod
ln
mv
rm
rmdir
touch
chgrp
groups
id
passwd
quota
find
gfind (GNU find)
split
fetch
df
md5
sha1
sha224
sha256
sha384
sha512
sha512t256
rmd160
skein256
skein512
skein1024
date
cksum

 

For example, you can run something like:

ssh user@rsync.net touch some/file

and then:

ssh user@rsync.net rm -rf some/other/file

The 'passwd' command, which is used to change your rsync.net password, is special, as it requires a '-t'

ssh -t user@rsync.net passwd

You can use the test command remotely, and return true/false to your local environment:

# ssh user@rsync.net "test -f fileThatExists"
#echo $?
0
