This package provides helper scripts for running sshd on ABCI compute nodes with user privileges.

• First clone, and generate hostkeys.

es $ cd ~
es $ git clone https://github.com/ogawa/abci-sandbox-sshd.git
es $ cd abci-sandbox-sshd
es $ ssh-keygen -f ./ssh_host_rsa_key -N '' -t rsa
es $ ssh-keygen -f ./ssh_host_dsa_key -N '' -t dsa
es $ cp sshd_config.tmpl sshd_config

• Update abci-sandbox-sshd/sshd_config to use your ABCI ID.

• Copy your SSH pubkey to abci-sandbox-sshd/authorized_keys.

• Run your own SSHD on an ABCI compute node.

es $ qrsh -g abci_group -l rt_F=1
gXXXX $ (cd abci-sandbox-sshd; /usr/sbin/sshd -D -f sshd_config)

• Connect from your local PC to sshd on the compute node.

clientpc $ ssh gXXXX -p 2222 -l abci_user -o ProxyJump='%r@as.abci.ai,%r@es' -A

To make things easier, add the following configuration to .ssh/config on your client PC.

Host gXXXX
     HostName gXXXX
     User abci_user
     ProxyJump %r@as.abci.ai,%r@es
     Port 2222
     ForwardAgent yes

and then,

clientpc $ ssh gXXXX

This package includes secure-shell-run.sh and secure-shells-run.sh that are example of dispatching single or multiple instances of sshd from a batch script.

es $ qsub -g abci_group abci-sandbox-sshd/secure-shell-run.sh

es $ qsub -g abci_group abci-sandbox-sshd/secure-shells-run.sh

• These scripts do nothing for keeping environment variables. To do so, store environment variables to a file before kicking sshd, and load them after establishing SSH connections.
