After a system crash, boincmgr would not start, just dies silently!

I strace'd boincmgr and discovered it last viewed this file /home/<ID>/BOINC Manager-<ID>, and once I removed it, it started up fine.

Excellent - you've just answered a problem I had about an hour ago, before I'd even asked!

In my case, the cause was slightly different: I'd absent-mindedly closed the BOINC Manager with the green (for Mint - red for most other distros) cross in the top-right corner. With a v7.16.1 Manager, this is known to be problematic - it's better to use the file menu 'Close' or 'Exit' (if available).

But the end result was the same - I couldn't reopen the Manager.

Same result from strace (under my own account - running as admin had, er, 'interesting' results). rm'd the file you indicated, and it works fine again. That one's going in the memory banks.

I just tried under Debian using the repo version of BOINC (7.10 in this case). It creates a "BOINC Manager-<ID> file in the users home folder while the manager is running. Its deleted when you exit the manager (successfully). I guess because yours crashed it got left behind.

It looks like its designed to prevent running more than one instance of the manager per user. I tried the "File -> New BOINC Manager window" option and not surprisingly it doesn't work.

I just tried the same thing on Mint with a v7.16.1 manager, and it did work - sort of.

A new blank window opened, but I couldn't get it to connect to any of my other (Windows) machines by name. I'll look up some IP addresses, and check my remote access settings, and let you know how I get on later.

Edit - mind you, that was with a private build Manager with some of the missing features put back in. I'll test with the repo Manager, if I can find a copy.

Having sorted out my networking, I can confirm that 'New BOINC Manager window...' is working for me, with both the full-feature v7.16 private build, and with the cut-down v7.16 PPA repo version.

Attaching to Windows hosts, I seem to have to connect by IP address first, but after I've done that, attaching by name seems to work - for the current session, at least.
