I'm using pdsh, but can't find any documentation or examples of specify the ssh key. Usually, I do ssh -i ~/.ssh/mykey.pem <address>. How do I change the pdsh command pdsh -R ssh -w ^server.txt "date" so I can specify my ssh key?

The manpage suggests an environment variable:

PDSH_SSH_ARGS_APPEND="-i $HOME/.ssh/mykey.pem"

You need to either export the variable (to make it available to pdsh's child processes) or define the variable and run the command in one go:

# Either:
export PDSH_SSH_ARGS_APPEND="-i $HOME/.ssh/mykey.pem"
pdsh -w^server.txt date

# Or
PDSH_SSH_ARGS_APPEND="-i $HOME/.ssh/mykey.pem" pdsh -w^server.txt date

I don't know why you gave -R ssh; for me it perfectly works without.

See also "pdsh can't find identity file, but ssh can. why?" on stackoverflow. The poster has a different problem (quoting) but uses the same approach.

  • I keep on getting Permission denied (publickey). I'm using a list of hosts names formatted with one host on each line e.g. 192.168.0.10. However, I also tried with ubuntu@192.168.0.10. Neither worked. – Soubriquet Sep 14 at 14:35
  • Permission denied (publickey). is a different error. It means you didn't distribute the corresponding public key to the remote hosts. Did you? – PerlDuck Sep 14 at 14:39
  • Nvm works. I forgot to add thr PDSH_SSH_ARGS_APPEND to my .bashrc – Soubriquet Sep 14 at 14:39
