How to provide additional ssh options?

[Kvit]

How can we provide additional options to ssh wrappers? For example:

• location of scp.exe / sftp.exe utilities on PC
• location of identity file / private key
• location of known_hosts on PC
• other options recognized by ssh/scp/sftp utilities

To make clp / sftp from Rstudio package work on windows I have to feed information about location of identity files and known_hosts. This line works for example:
ssh -i C:/Users/me/.ssh/key-do-private.ppk -o UserKnownHostsFile=C:/Users/me/.ssh/known_hosts root@123.456.78.90
But this info needs to be fed into ssh wrappers

It looks like you have a place for ssh_options() in the code, but how can we feed additional options to this function? Would it make sence to expose this function so we can populate options from R code?

thanks @Kvit for the issue

@jeroen do you know if ssh package can already handle any of the items mentioned above?

[jeroen]

With the ssh package we don't shell out to scp.exe so this is not relevant. The private key is set in the keyfile parameter in ssh::ssh_connect().

thanks @jeroen

@Kvit what version of analogsea are you running? Install from ssh branch and then see droplet_ssh where you can pass a path to a keyfile parameter that's passed to ssh::ssh_connect

[Kvit]

I'm using current CRAN version of analogsea, windows 10 and the current version of Rstudio with bundled ssh / scp / sftp . I was trying to use function droplet_upload() and pass ssh flags there. It is possible to make scp / sftp work from R without analogsea function wrappers, but using analogsea functions would be more convenient for working with DigitalOcean

@Kvit can you try the ssh branch? This will probably soon be the cran version.

devtools::install_github("sckott/analogsea@ssh")

[sckott]

@Kvit did you try it?

sorry, was tied with other projects, will try and report back
