Details described here: https://setiathome.berkeley.edu/forum_thread.php?id=81632&postid=1892079 Bug is repeatable, I see it on ~8 hosts too. |

With the --no_gui_rpc switch you're telling the BOINC client not to send out any remote procedure calls, aka it's not communicating with anything out there (BOINC Manager, boinccmd, the screen saver, remotely controlled BOINC, any of the projects that support communications by RPC, etc.) It's essentially deaf, mute and stupid. I've tried finding when the option was added and what it was for, but apparently it happened before I switched to gmail, and I didn't retain the emails from the previous ISP. So that makes searching a little more troublesome. I've now asked David about it. Let's see what he comes up with. |

0d2a0ad9a3124776c45458f83fddfe75b0924117 davidpanderson committed on Jul 23, 2005 + - Core client: add "-no_gui_rpc" cmdline option. + If present, don't create listening socket for GUI RPC. + (Useful if bind() doesn't work).See how that compares with what David remembers. |

He pointed me to the checkin notes 2005, same date, same message. Plus said that a client doesn't need GUI RPCs to do computing.. There. If it's broken, I don't think there's going to be a fix made for it. Easier to remove the option, because anyone can run the client on its own these days - which they couldn't when this option was added for BOINC 4.71 -- Oh my, anyone remember that version? :) |

And It was added when manager and client were separate, otherwise there would have been no GUI RPC. It's necessary for security-conscious users. GUI RPC is a potential security vulnerability. I've put it in Github: Issue #2150 |

David found what ailed this and is putting a fix into a PR. |

David found what ailed this and is putting a fix into a PR.Good. But that's one I would leave until v7.10.x, and let the real programmers have a good look at it. |
