Everett Toews's questions

I'm switching from HAProxy to Pound and I need to know if there is an equivalent of

option forwardfor
option httpclose

in Pound.

BTW, I'm already using the

HeadRemove "X-Forwarded-For"

in Pound.

Thanks

If I modify the source code of some package that I've installed with apt-get in Ubuntu, is there some package tool that will let me see the diff between what was the original installation and my modifications?

When I try to remove a logical volume I get the message

#lvremove /dev/my-volumes/volume-1 
Can't remove open logical volume "volume-1"

#lvchange -an -v /dev/my-volumes/volume-1 
Using logical volume(s) on command line

How can I force the removal of this volume?

I need to do a rsync from a target server with a server in the middle and I have the same public key on both the target and middle server. I want to use that key so I don't have to do password authentication.

local --ssh--> middle --ssh--> target

Reading Method 1 of Using rsync through a firewall makes it seems like this is doable but I have been able to figure out the ssh part of the syntax of the command yet.

When I try

ssh -i $KEY -A user@middle ssh user@target

I get

Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password).

Clearly the agent forwarding isn't happening as I was expecting it to.

Ideally I'd like to fit it all in one command without have to put anything in ~/.ssh/config files. What are all of the steps to do an rsync in this situation?

I want to install PostgreSQL 8.4 (or any service) on Ubuntu 10.4 (or any Linux distro) without it starting up as part of the installation. Right now when I do a

sudo apt-get install postgresql-8.4

part of the installation process is

Starting PostgreSQL 8.4 database server                   [ OK ] 

I really don't want PostgreSQL to start just because I'm installing it because I want a chance to change some config files before starting it for the first time.

Any thoughts on how to do this or if it's possible at all?

Thanks, Everett
