SSH

The secure server connection can cause slow-downs - some suggestions here. The idea is to either disable DNS or give an IP the VM can see.

Disable DNS

Open a terminal

Login as root (su)

Run gedit

From gedit, open the file /etc/ssh/sshd_config

Search for UseDNS, uncomment and set to no:

UseDNS no

Example:

tic,[s,r] = cspm_sshlinux_sendcommand( 'echo $SUBJECTS_DIR' ),toc
