Re: [Fab-user] How to specify pem file path when using gateway in Fabric

[Roshan Shetty]

I have checked Proxy command option 

ProxyCommand ssh address@hidden nc %h %p

But it won't work for me.

Reason is : i have multiple destination hosts (more than 100)

My script can login to any one of the destiation server based on IP entered. However gateway host is same all the time.

How can i configure Proxycommand for my scenario.

host 1 -> gateway -> hostA

host 1 -> gateway -> hostB

host 1 -> gateway -> hostC

host 1 -> gateway -> hostD

----------------------------------- (same above scenario continues for 100 servers)

Anyone can please post a code snippet ?

Roshan

Are you using ProxyCommand with corkscrew and IdentityFile for your jump host?  I have the exact same setup, and I am able to jump through gateway and access internal hosts with fanric.

I tried to use `env.use_ssh_config`

But it's not working.

because Fabric is not using the ssh config file of gateway server. So it will prompt for password

You could try using `env.use_ssh_config` instead of gateway, and use a local ssh client config that works how you want outside of fabric (i.e. you can log into the final host through the jump host using the existing keyfiles, using ProxyCommand/IdentityFile).  I suppose that fabric instructed to use that config *should* then work as well (but I don't know for sure, apologies).  Here is an SO answer that seems to explain how to do what you are asking with ~/.ssh/config: http://serverfault.com/a/337328

Hi,

I have asked this question on stack overflow but i haven't received any response.

My scenario:

Local host -> Gateway -> Remote host

I am using env.gateway variable to specify gateway host.

sample code

`env.user = "ec2-user"

 env.key_filename = ["/home/ec2-user/.ssh/internal.pem","/home/roshan.r/test.pem","/home/ec2-user/.ssh/test2.pem"]

 env.hosts = ['x.x.x.244', 'x.x.x.132']      
 env.gateway = 'x.x.x.189'

 def getdate():
      content = run('date')

`
My problem is with pem key path.

/home/roshan.r/test.pem is located in current directory. which is used for login into gateway server.

Other two mentioned pem files are located in gateway servers. Those will be used to login to next machie.

When i run this program i'm getting file not found error.

Thanks for any help !!

Regards,

Roshan
