How to use `~/.ssh/config` setting for each server by `rsync`

Question

I'm now using rsync with -e 'ssh -p 10022' option to specify the port.

I have already ssh setting in ~/.ssh/config.

Host myvps
  HostName example.com
  User ironsand
  Port 10022

Can I use this config from rsync easily? Or Can I create ~/.rsync and set a default port for specify server?

Solution 1

Specify "myvps" as the hostname.

rsync /var/bar myvps:/home/foo ...

Solution 2

This did not work for me. I have jump hosting in my ~/.ssh/config

Host 10.x.y.z
    User cloud-user
    HostName vm-pivot
    IdentityFile /path_to_vm_key

Host 21ct-dev1-*
    User cloud-user
    HostName %h.example.com
    ProxyCommand ssh 10.x.y.z -W %h:%p
    IdentityFile /path_to_vm_key


rsync -e "ssh" local_path vm-app01:/remote_path

ssh: Could not resolve hostname vm-app01: nodename nor servname provided, or not known rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: unexplained error (code 255) at /SourceCache/rsync/rsync-42/rsync/io.c(452) [sender=2.6.9]

However, this works just fine

[kbroughton@kbroughton:project + (develop)] ssh vm-app01
Last login: Thu Apr 17 12:10:37 2014 from 10.a.b.c

Edit, I was able to get past the name resolution by forcing rsync ssh to load a config file with -F sudo rsync -az -e "ssh -F /Users/kbroughton/.ssh/config"

This gets past one error but onto another. Permission denied (publickey,gssapi-keyex,gssapi-with-mic). ssh_exchange_identification: Connection closed by remote host

Also tried explicitly setting -i and user@ in the connection but same error occurs.

EDIT

Another data point. If i use the floating ip of the pivot vm (jump host) instead of its name vm-pivot rsync works. But explicitly dumping all my ssh/config in the -e "ssh" does not work. Details: local mac, upgraded to rsync 3.1.0, remote centos rsync 3.0.9.

[kbroughton@kbroughton:project + (develop)] sudo /usr/local/bin/rsync -az -e "ssh -F /Users/kbroughton/.ssh/config -i /Users/kbroughton/.ssh/identities/vm_key -W 10.x.y.z:22"  /var/data/sources/data.tar.gz user@vm-pivot:/home/user

protocol version mismatch -- is your shell clean?
(see the rsync man page for an explanation)
rsync error: protocol incompatibility (code 2) at compat.c(181) [sender=3.1.0]

This works

I realized that in my case I could not use the shortcut, but actual full host name could be used

doing rsync from user home dir where ssh config is kept, worked for me, even it supports node hoping.

This answer seems to be more of a working through of issues that are not directly related to the current question. It may be better presented as a separate question and answer, if a explanation of the issue and the solution could be formulated. The main issue seems to be that you don't actually use a hostname listed in your SSH configuration.
