I created a sliver today on the slice pgeni.gpolab.bbn.com/ecgtest2, containing two VMs on pc3.utah.geniracks.net. The web details page, ​https://boss.utah.geniracks.net/showexp.php3?pid=pgeni-gpolab-bbn-com&eid=ecgtest2#details, contains:

SSHD Port allocation ('ssh -p portnum'):

Looks like a small perl bug of some sort.

Two prospective issues related to password-based login to ops.utah.geniracks.net:

1. Remote password-based SSH login to my user account (chaos) succeeds. Is there a plan to protect against password-guessing attacks on user accounts, which can be shared with site admins?
2. Since /etc/ssh/sshd_config contains:

   PermitRootLogin yes
   

   I am concerned that password-based root login may in fact be permitted on ops. Is that the case? If so, could this setting be changed to without-password?

I created an OpenVZ container on pc5.utah.geniracks.net. I notice that /var/log within the container appears to be empty. I would expect logs from the container's userspace to be stored in /var/log within the container for the experimenter to access.

Output of /var/log, being empty:

Uname, fyi:
