Does it work with Sun Grid Engine?

This repository looks fantastic. Would be great to use it at work, but unfortunately after SSHing onto the remote cluster I have to log onto one of our nodes to do the work. I followed your tutorial and suspect that this additional step could be the reason why I can't get it to work at the moment. Instead, in R I get this kind of output after reloading the localhost:4321 website (which doesn't refresh on its own for me):

> channel 5: open failed: connect failed: Connection refused
channel 5: open failed: connect failed: Connection refused
channel 5: open failed: connect failed: Connection refused

Just asking in case you have some experience with this kind of environment. I apologise if this is not enough information to understand what the problem is. If so, let me know and I'll explain in a bit more detail later.

Thanks!

I have done multi-hop ssh with forwarding in the past but it's been a while. This should be possible - see, for example, the second answer to this question here: https://superuser.com/questions/96489/an-ssh-tunnel-via-multiple-hops

Hi,

I got it to work with the SGE cluster I have access by taking advantage of the names of the compute machines in our SGE cluster. All nodes start with compute. So this is what I have:

Local machine ~./ssh/config:

Host sge
    User my_username
    Hostname my_cluster@somewhere
    LocalForward 4321 localhost:4321
    ForwardX11 yes
    ForwardX11Trusted yes

I guess that forwarding X11 is there for historical reasons, or in case that rmote fails and you don't want to have to restart your terminal.

    ForwardX11 yes
    ForwardX11Trusted yes

~/.ssh/config at SGE cluster

Set up local forwarding for all compute nodes in my SGE cluster. This http://pentestmonkey.net/cheat-sheet/ssh-cheat-sheet was useful to me btw because I tried first with RemoteForward.

Host compute*
    LocalForward 4321 localhost:4321

~/.Rprofile at SGE

Force all different terminal windows to use the same server_dir for start_rmote() so that they all update in the same location.

## rmote for images
# https://github.com/cloudyr/rmote
installed <- require('rmote')
if(!installed) {
    cat('install.packages("rmote", repos = c(CRAN = "http://cran.rstudio.com",
tessera = "http://packages.tessera.io"))')
} else {
    start_rmote(port = 4321, server_dir = '/users/my_username/rmote/rmote_server')

    ## This also works
    # start_rmote(port = 4321, server_dir = paste0('/users/my_username/rmote/rmote_server_', Sys.Date()))
}
rm(installed)

In reality I chose a different number from 4321 for the port, so that it won't conflict with other users if they use the default value in rmote::start_rmote().

Best,
Leo
