ssh-add over ssh

ssh-add picks up the agent fine when using X11, but when logged into a remote ssh session:

michael@apollo:~$ ssh-add
Could not open a connection to your authentication agent.

Ah, we have to fire up ssh-agent and cut/paste the env variables…

michael@apollo:~$ ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-erlzEU7907/agent.7907; export SSH_AUTH_SOCK;
echo Agent pid 7908;
michael@apollo:~$ SSH_AUTH_SOCK=/tmp/ssh-erlzEU7907/agent.7907; export SSH_AUTH_SOCK; SSH_AGENT_PID=7908; export SSH_AGENT_PID;
michael@apollo:~$ ssh-add
Enter passphrase for /home/michael/.ssh/id_dsa:
Identity added: /home/michael/.ssh/id_dsa (/home/michael/.ssh/id_dsa)

Thanks, Brandon! 😉

Debian Sarge(ish) x86-64 Xen Installation

Following along a great article, titled, “Debian Sid gets Xen 3.0”, I set up a minimal Debian Sarge AMD64 install from debian-31r0a-amd64-netinst.iso for use as a Xen development server. The full text of this post contains my step-by-step how-to on my successful installation.

I ran a default netinstall installation, selecting no additional software packages, and used the “multi-user workstation” partitioning scheme, which segregates the /, /usr, /var, /tmp, and /home partitions, with most of the disk using /home, where the Xen virtual machines will reside.

Bang the link below for my full notes!

lftp> mirror

I have been a big ncftp user for many years, and I am really starting to like lftp – escaping the lftp shell for command-line access and the way lftp maintains session persistance through re-authentication have made me a believer.

I found a little mirroring issue with the Smarty cache from the CMS application, CMSMadeSimple, that I am using for a site, and found the following works nicely to mirror to my local working directory, while excluding the Smarty cache files:

lftp> mirror --no-umask -x tmp/templates_c/* -e
Total: 138 directories, 1004 files, 0 symlinks
Removed: 0 directories, 3 files, 0 symlinks

I need to tinker a little with reverse mirroring options to get things just right 😉


A Must Read: “Three Cups of Tea”

A book for our friends, our country, our leaders, our time.

“The first time you share tea with a Balti, you are a stranger. The second time you take tea, you are an honored guest. The third time you share a cup of tea, you become part of the family,” Mortenson recalls Haji Ali as saying.
