use all ~/.ssh/config parameters

[klucar]

I can't seem to get anything working with my .ssh/config file. The instructions say that it will use a key from .ssh/confg but it doesn't seem to use host aliases, or user names from the file.

Here's a pretty typical .ssh/config entry for me.

Host host_alias1 host_alias2
    HostName 1.2.3.4
    User myuser
    IdentityFile ~/.ssh/myuser_key.pem

It would be nice to fully read the config and use everything so I could just do a

ssh_connect('host_alias1')

and things would just work.

Can you post your libssh_version() and output for ssh_connect('host_alias1', verbose = TRUE). Also which OS do you have?

[teramonagi]

@jeroen (Maybe) i have the same error with @klucar. I use Mac OS (10.14.6).I can use these .ssh/config settings from the terminal.

I hope that this information will be useful for u to solve this problem

I also have this issue, and my libssh version is also 0.8.6. That is, I cannot use a Host defined in my config file. The config file is a file within the path specified by ssh_home(). I'm on a windows box, and here is that call:

suppressPackageStartupMessages(library(ssh))

libssh_version()

## 'ds' is a name defined in my 'config' file in my ssh_home() directory.  Normal ssh functions work fine.
session <- ssh_connect("ds")
#> Error: libssh failure at 'connect': Failed to resolve hostname ds (No such host is known. )
