vaniacer / sshto Goto Github PK

hi,

there are some errors when running on macOS

./sshto
./sshto: line 479: declare: -A: invalid option
declare: usage: declare [-afFirtx] [-p] [name[=value] ...]
./sshto: line 566: declare: -A: invalid option
declare: usage: declare [-afFirtx] [-p] [name[=value] ...]
./sshto: line 568: ${name,,}: bad substitution

Thanks

I have a file ~/.ssh/config with the following content
Include conf.d/dbofl.config Include conf.d/my.config Include conf.d/fap.config
And sshto doesn't handle include files

Hi, there is no license included, and by default it means it cannot be used/copied/shared.

Is it possible to use sshto from a Virtualbox client installation?
After running sshto, only the contents of the current directory is printed.

dialog --version
Version: 1.3-20201126

I would like to propose a feature to navigate the menu using j/k directional keys (vim keys)

Less moving the hands from home row the better.

Thanks.

I'm sure this is a user error, but I can't find a solution for it. I have (1) Ubuntu server that I created an sshto entry for in my config file. Its' entry is simply: hostname (ip address), user remote user account), port 22. That is it. When I execute it, I am prompted for a password, which I enter and then I get "bash: Server: command not found" and the next key press closes the session. If I go to a command prompt and try ssh (username)@(ip address), enter the same password, I get a command prompt. Any idea what is causing my issue?

Thanks!
Jon

If the user is using sshto in tmux or GNU screen, dynamically re-title the window to the hostname that we are connecting to. Upon disconnect, revert to previous title.

I've tried to get this working locally, but wasn't happy with the results.

Just found this script (exactly what I've been looking for) & running this on MacOS and I found the following two issues that I can fix via PR if you'd like.

1. If dialog not installed on the system, the script recommends I run the command sudo apt-get install -y dialog where I use brew install dialog on my MacOS system.

2. When you exit the dialog, you get the following error due to the ls --color=auto command.

ls: illegal option -- -
usage: ls [-ABCFGHLOPRSTUWabcdefghiklmnopqrstuwx1] [file ...]

Let me know if you'd like me to code up these fixes using uname -s detection of a MacOS system.

Thanks!

I'm looking for a way to add optional tags to a host and have sshto act on those tags.

Specifically, in my environment I have certain hosts that are live and hosts used for testing, as most people probably do. One of the fast ways I differentiate this is by making the background color of the production hosts different from non-production hosts, and I use a kitty browser kitten to do this.

What I'm now trying to do is add a tag to the end of a host description in an sshconfig file, say Host prod_serv #Production Server#PROD and then have sshto run a different ssh command when it sees that PROD tag. Where I'm running into trouble is I can't quite figure out how to make sshto see the tag or created variable when go_to_target() is called. Below is what I have so far, and any suggestions or advice you can provide is greatly appreciated. I couldn't find a way to highlight the specific lines I added, so the edited portions in the second code block are preceded with four underscores (____). Please be forewarned I'm no programmer so it would not surprise me to learn I'm approaching this all wrong.

Edit: I suppose I should have included what behavior I'm seeing now. It does not identify the $prod variable in the go_to_target function and so always executes the else statement. In the past I've just put all production servers in the same group and used the $group_name in the if/else statement, but I'd like to get away from having to keep unrelated production servers in the same group.

#------------------------{ SSH to target server }-----------------------------------------------------------------------
go_to_target(){ clear; 
  if [[ $prod == *"PROD"* ]]; then
   kitty +kitten ssh $SSH_OPT $target || pause;
  else
   ssh $SSH_OPT $target || pause;
  fi
}

In the SSH config file, multiple space-separated entries on the Host line can resolve to the same set of configuration options. For example:

Host pear peach plum 
     Hostname %h.orchard.gardenparty.org
     user farmer
     IdentityFile ~/.ssh/id_rsa_orchard_20240109

In this case there are three different hostnames our farmer@ might want to get connected to with this private key and other settings. But sshto will only show the first host, pear, leaving no way within sshto for the user to connect to host peach or plum.

This is an enhancement request to render those space-separated aliases on the Host line as individual hosts.

One possible workaround would be for the user to manage a (far more verbose) .ssh/config file with a separate identical entry for each host. The challenge there is it would hamper adoption from users who have a maintained their config file manually, efficiently so far.

Another consideration is there are wildcard options for both the Host and Hostname parts of the configuration here that could expand beyond what sshto could possibly know from the config file, potentially making a need for another interactive dialog.

Is it possible to make it so that known_hosts is scanned for list of available servers and not just config?

sshto doesn't use configuration files included in .ssh/config.

Example setup:

❯ cat ~/.ssh/config
Include ananas/config
Include github/config
# blah-blah

/tmp
❯ cat ~/.ssh/github/config
# vim: filetype=sshconfig:

Host github.com
    User git
    IdentityFile ~/.ssh/github/kapsh_github

When all hosts (except default options for Host *) are configured in this way, sshto just shows nothing and exits.

Dialog doesn't like the new awk list creation (commit 68ad4dd). Specialy this line create problem:
--menu "Select host to connect to. $USERNOTE" 0 0 0 "${list[@]}")

Dialog error message is
Expected at least 20 tokens for --men, have 4.
followed by
ESC[0mESC[?25hESC[HESC[2JESC[3J
followed by current directory content.

Unrelated, but additonaly only few lines of the output can be seen, and the output is not browsable (terminal window looks locked at current screen).

It is a known issue with Dialog, very similar to this old error on slackware. Browse at the bottom for explanation.

I get this error

after install gawk it was fixed for me

sudo apt install gawk

may be should add this to readme or checking in sshto script?

I just reloaded one of my machines and did a fresh clone of the repo. Using the same config file as before, the updated version of the script no longer seems to honor the #Host DUMMY #SiteName# moniker anymore, it just shows all hosts in a single, large list.

As title says - add zsh support. Otherwise I cannot run the project on my Apple Air M2.
One more thing - if I try to run it trough bash I got (on latest OS with all updates passed and brew upgrade as well):

BASH version 4.2+ required to run sshto, your is - 3.2.57(1)-release

Thanks.

Just watch the video, happens when closing with hitting Esc and when selecting Exit menu option.

my ~/.ssh/config looks like this:

Host *
ForwardAgent yes
ServerAliveInterval 120
IdentityFile /path/to/default/default/ssh/key
...
Host gate
User tim
Hostname 1.2.3.4
Port 22
LocalForward 1234 192.168.1.1:1234

after running sshto and selecting host gate I got error: Name or service not knownname gate

my default shell is zsh. But I run /bin/bash before starting sshto. I use Linux Mint 21.2

There's some issue with declare option -A
