Here's the problem -- fixed, but not solved: A small LAN with three boxes and hardwired ethernet connections through a router. PuteF: server, running FC15 (x86) and LXDE PuteB: running FC13 (386) and gnome PuteD: running FC15 (386) and KDE I can transfer files between PuteB and PuteD using scp without any problems. Regardless of which machine the scp is initiated on, all file transfers between PuteF and PuteB, and between PuteF and PuteD fail with the error message "Corrupted MAC on input. Disconnecting: Packet corrupt. lost connection." The time this takes to happen varies within a few minutes. Things tried without success: (1) installing a new ethernet card on PuteF and connecting it to the router with a new cable (2) connecting PuteF and PuteB using every possible combination of ports on the router (3) running a new long ethernet cable directly from PuteB to PuteF (4) reinstalling FC15 (x86) on PuteF (5) installing the 386 version of FC15 on PuteF What worked: Installing FC14 (x86) on PuteF -- which, obviously, is only a short-term fix. Is this a bug in FC15? Or a feature of FC15 that can't deal with my older hardware? Assuming the latter, how old is "too old" hardware for FC15? I bought the box (Intel dual core with 4GB memory) in 2007 from one of those priceless dealers who builds them and is then a victim of his success. There haven't been any problems with this box (despite a lot of use) until a hard drive crash about a month ago, when I took it into the shop for a full checkup. (Presumably this would have included memory diagnostics.) The hard drives are also new. I started having these problems as soon as I installed FC15 (x86). -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
