Start screen irssi on boot - foldem - 2006-08-13

I've been using screen + irssi for a while now (ssh from work to home :)), but in the last weeks I have had to deal with some power outages. So I have been wondering a couple of things

1. how do I start screen and irssi as a certain user on boot.

2. how do I configure that the pc starts back up when the poser returns (prolly A bios option but don't wanna reboot it (great uptime now :P))

Quote:1. how do I start screen and irssi as a certain user on boot.

Certainly it is possible. In fact I use it! I used this source here. This requires a utility called "start-stop-daemon". If you don't have that then you can download this and compile it but most system have it now a days.

Any issues just as me! :)

Yeah has to be a bios option, look for power options, particular restart on power loss .. etc.

Another possibility is to use cron which has the nice @reboot option.

Edit your crontab with:

Code:
$ crontab -e

Then add this:

Code:
@reboot /usr/bin/screen irssi

Some issues with screen can result in:

So one work around that I have figured out is this:

Code:
% ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/mark/.ssh/id_rsa): /home/mark/.ssh/id_localhost

Enter passphrase (empty for no passphrase): 

Enter same passphrase again: 

Your identification has been saved in /home/mark/.ssh/id_localhost.

Your public key has been saved in /home/mark/.ssh/id_localhost.pub.

The key fingerprint is:

7c:63:29:a2:ae:08:ed:8b:ff:15:63:1a:7e:9f:14:22 mark@tone

% cat /home/mark/.ssh/id_localhost.pub /home/mark/.ssh/authorized_keys >tempfile

% mv tempfile /home/mark/.ssh/authorized_keys

mv: overwrite `/home/mark/.ssh/authorized_keys'? y

% vi .ssh/config

(add this into the file)

Host lo

HostKeyAlias localhost

HostName localhost

IdentityFile /home/mark/.ssh/id_localhost

User mark

Port 22

(save the file)

% ssh lo

Last login: Sat Jan  5 14:47:41 2008

% exit

Connection to localhost closed.

Now we have a working connection to localhost. So what we want in our crontab is this:

Code:
@reboot ssh lo screen -d -m irssi

Tada .. work around complete. You might need to make the public key entry under root's account if you use the global crontab.

So, ZNX and I couldn't get this working at all. Something was preventing my machine from accepting the public keys. Well here is the fix I finally found, hours later.

I added the following line to my users crontab with crontab -e

Code:
@reboot /usr/bin/screen -d -m irssi

We had tried this as @reboot /usr/bin/screen irssi, which did not work.

Hope this helps someone cause I know I found very little helpful info from my searches online

Why the heck didn't I try that first .. heh anyway!
