Hi,
I have a very simple problem, but I don't know how to solve it. I use Bonic Manager to connect my computers remotely. Each name/address is remembered by the software and I have pretty long list now. Can anybody know how I can clear the list of hostnames? I cannot find such option neither in the GUI nor I cannot identify any file in which the data can be stored.

Assuming you're asking about BOINC running on Windows, the computer names are stored in the Registry, in a MRU (Most Recently Used) list.

The list is held at

[HKEY_CURRENT_USER\Software\Space Sciences Laboratory, U.C. Berkeley\BOINC Manager\ComputerMRU]

and can be managed using the Windows utility regedit. Be very careful not to make any unintended changes to other registry keys or values while you're there - indiscriminate editing of the registry can be dangerous.

Thanks for your reply. I use Linux, so I don't have any registry. Maybe you know how to clear it in Linux version....

I don't use remote access, but this sample file is in my Mint Linux:

/var/lib/boinc-client/remote_hosts.cfg

It contains:
# This file contains a list of hostnames or IP addresses (one per line)
# of remote hosts, that are allowed to connect and to control the local
# BOINC core client via GUI RPCs.
# Lines beginning with a # or a ; are treated like comments and will be
# ignored.
#
#host.example.com
#192.168.0.180

Now you're asking ...

There's a hidden file

.BOINC Manager

in your home folder. That contains the section

[ComputerMRU]

about 20 lines in.

Thanks, this is exactly what I was looking for:)
