    Localhost traffic puzzler after upgrade from 12.3 to 13.0

    You can name VLAN interfaces anything you want, nearly, with the right config. VLAN 10 is functioning normally passing traffic normally. The ifconfig output was apparently truncated when I edited my message. Oops. Here's the missing bit that confused you:

    IPFW Filtering ICMP with ipfw Q: icmptype AND code?

    Sadly the hosts I need to use this on are tightly bound to existing ipfw rulesets. *sigh*

    IPFW Filtering ICMP with ipfw Q: icmptype AND code?

    That's not what I'm trying to do. I am not sending a response. I want to match ICMP packets, NOT reject with an ICMP code. Thanks.

    IPFW Filtering ICMP with ipfw Q: icmptype AND code?

    I know I can have ipfw rules matching the ICMP protocol and specify one or more icmptypes. But how do I also match on the ICMP type's code (those that have such)? For example I can easily match ICMP type 3 (destination unreachable) messages: ipfw add 1000 count log icmp from me to...

    Bhyve newbie: "vm_create: Device not configured"

    Haha, I went exploring my BIOS to look for a VM setting for the CPU before posting my woes above, but couldn't find it anywhere. But with giving me "SVM" as a search term, I was able to discover it was hiding in the OVERCLOCKING section of my BIOS--not in the ADVANCED section. Thank you!

    Bhyve newbie: "vm_create: Device not configured"

    I figured I'd mess around with bhyve a bit on on e of my FreeBSD systems. Unfortunately it isn't cooperating, and bhyve is not being helpful by pointing out where my basic config. is going wrong. Some background: # uname -av FreeBSD vin.tambler.com 12.1-RELEASE-p7 FreeBSD 12.1-RELEASE-p7...

    ZFS Help me track down random CRAZY SLOW IO

    From ps while the dd process is stuck on open(): user 41606 0.0 0.0 10852 2468 4 DX+ 14:04 0:00.00 dd if=/dev/zero of=io_test1.txt bs=1M count=1000 I don't notice any zfs iostat fluctuation outside of the expected moment-to-moment fluctionations, but I've not been able to...

    ZFS Help me track down random CRAZY SLOW IO

    Thing is, I don't have a clue what causes the problem. Just that random open()s appear to hang sometimes. I can't consistently control when it happens, and don't know why. I am attempting to gather more information so I can narrow it down. You are very correct, reporting a randomly occurring...

    ZFS Help me track down random CRAZY SLOW IO

    This is a very real world problem. These non-real world tests were created to try to find the actual problem. This affects vi sessions, has made a PLEX server in a jail pretty much useless, slowed down email services on a Postfix and Dovecot server running in another jail. Do NOT discount the...

    ZFS Help me track down random CRAZY SLOW IO

    Some more data doing time truss -d dd if=/dev/zero of=io_test1.txt bs=1M count=1000 in one SSH shell and time truss -d dd if=/dev/zero of=io_test2.txt bs=1M count=1000 in a separate SSH shell, both in the same user's home directory both locked up. A third simple echo "text" > out.txt executed...

    ZFS Help me track down random CRAZY SLOW IO

    I will respectfully disagree. My test showed the problem clearly. The first three runs were normal. The last run took over 46 seconds to complete. Using /dev/zero. I agree that for testing throughput on a normal system, a bigger file size, and some other source of data would be appropriate...

    ZFS Help me track down random CRAZY SLOW IO

    Sorry, I didn't make it clear. The first three runs of the test work just fine as you both noted. Please check out the fourth and final run. That one hit the random, unpredictable issue. It took 46+ full seconds to complete: real 0m46.998s I will re-edit my post so readers will see that...

    ZFS Help me track down random CRAZY SLOW IO

    I have a system exhibiting bizarre slow IO (or paused IO as if there was a deadlock) at random times that appears to affect almost any process doing disk IO. Here's a quick example from the command-line where I had to execute a time dd if=/dev/zero of=io_test.txt bs=1M count=1000 four times to...

    jail.conf jails won't start Q - 2 bugs

    So I've got a FreeBSD 10.3 host with three jails that use nullfs to mount a common read-only base system. I've discovered that on reboot, only one or two of the three will start, and I cannot predict which ones. The remaining jail (or jails) fail to start. There are NO logs anywhere on the...

    Multiple routing tables, jails, and setfib

    Hi, So I'm finally getting around to trying out setfib and running multiple routing tables. However, I noticed one behavior I need to avoid, bypass, or work around. For example, say I have a machine with 2 network interfaces, re0 and re1, with re0 a part of the default FIB 0 and re1 a member...

    File system notification?

    Perhaps I should rephrase my question: Is there a useful (i.e. in the mainline FreeBSD kernel) functionality now since the 2010 summer of code project? That is, did any of it get integrated into the system? Does anyone know? I don't plan on diving into unfinished, non-integrated code and...

    File system notification?

    Hi, Does anyone know of progress on a file notification system for monitoring changes to a set of files/directories/subdirectories? Ilya Putsikau had a 2010 summer of code project in this area. Anyone know what happened to that code? Was anything useful developed? All attempts to find...
