Unfortunately it is not really reproducable. Sometimes (like once a day) all remote checks that use ssh fail with that error message: fcntl(0, F_SETFL, O_NONBLOCK): Inappropriate ioctl for device They produce a warning, but fail 3 times, so no more checks are done, and I have to reschedule each check by hand, to get the state changed again. Then it works fine again for some hours. The problem did not occur before my update to 4.4-STABLE, and OpenSSH 2.9. I have to say, that there was ssh 2.9 installed on this system already (from the ports) before, but I guess there are differences to the one now included in the system. >How-To-Repeat: Tricky: install netsaint and plugins, define a service which is checked on a remote machine, it doesn't seem to make difference which ssh is used on the remote machine (I've had FreeBSD boxes and Solaris with different versions of OpenSSH). Start netsaint and wait until you get warnings about the checks failing with the error message above. >Fix: sorry, no idea. Not beeing able to reproduce this problem in a defined environment, doesn't help. :( >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
