Okay, I apologise for posting what has probably been asked several times, but I check 8 pages deep in here, and Paul's website is giving me a 500 error, so...

How do I set up the Select computer?

Jordan, Assuming that you have a network of machines, you need to Put a file called "remote_hosts.cfg" in the BOINC folder on each system.
This file should contain a list of the IP addresses of the systems can are allowed to remote control e.g.
#
192.168.0.1
192,168.0.2
#
Restart BOINC on these machines, then Select Computer should allow you to connect and control one system from another.
There is a password option, but I've never used it so I can't say what you do with this.

Aha, very interesting information. I’ve been wondering about this a couple of times as well.

I do have another question regarding this – is it possible to use the computer name as well? Reason for me to ask is that I use DHCP at my LAN.

Thanks and Happy Crunching

You can use fqdn (full qualified domain names) in this file, if you have a DNS server in your network, who can resolve it. You may have to create a reservation in DHCP, otherwise the IPs for the hosts may change.
It works great for me, but I'm in an Active Directory Domain, so it's expected to work.

Good luck and ceep crunchin

The Wiki is up ... I am trying to get the provider to get their act together ...

So, I changed my signature so you should be able to get to the Wiki separately from the old site... though the question you asked was NOT in the old site ... it IS in the Wiki ... look for "remote hosts" ...

Evan have a sample in there ... see ... people complained I did not have enough examples ... now they are EVERYWHERE ... :)

You never can have too much information. Great work Paul, keep it up!



To truly explore, one must keep an open mind...

It can contain either the IP address or the machine name one per line

10.90.46.100
foo

The above entries would allow computer foo and whatever computer was at 10.90.46.100 to connect.

I put the IP and name on the same line separated by a space.

Works for me.

Sigh, there must be something else that I'm not seeing... maybe it's the Linux firewall, sigh, wish I had paid attention during that class... Okay, what ports do I need to blow open?

After you put the file "remote_hosts.cfg" in the BOINC directory of the machine you want to control and restart BOINC manager, do you see a message "remote control allowed"?

1043 and 31416. The daemon will attempt to use 1043, and if that is not available, it will attempt to use 31416. The manager tries both to see if anybody is home.

So firewalls on both sides need to have those ports forwarded.


I'd rather speak my mind because it hurts too much to bite my tongue.

On the daemon side, they need to be opened inbound. On the manager side, they need to be opened outbound.

OK then I can honestly say it's not working.. I have one computer I have experimented with that on and it failes to connect.

Works fine when I use my VPN connection though...

OK, that is the way that I thought it worked. I know that it works without firewalls, so, I must be misinformed about what all directions the ports must be opened.

Thanks folks... it was the linux firewall... now all I need to do is figure Samba out so I can use boinclogx... sigh

[EDIT:]

Well, again, it was the firewall... Ya know, Linux is great, but when /dev/hda crashes, and you have to rebuild (granted I was planning to anyways because I bought a new server), setting everything back up is a REAL PAIN!!!
