    Network goes away after some time

    Does it still have an IP? Has it's DHCP lease expired? If it still has an IP, can you ping the gateway? But before you do that, look at the arp table. Then look at the arp table after you ping the gateway.

    Network goes away after some time

    Yes, sounds like firewall issues. Some firewalls will time out inactive TCP sessions. At $JOB we have a 30 minute timeout for inactive TCP sessions. Configuring TCP sessions, setsockopt() or globally, works around the problem. I doubt ICMP ECHOs will keep TCP sessions alive. Though I suppose...

    IPF ipf use dhcp/pppoe interface ip in ruleset

    pass out log all: Why log all packets? Where in your ruleset is this rule. Placement where it is in the ruleset matters, hugely. Also, quick rules are checked before this rule. My VPN, using ssh, has an interface. Do you use IPsec? IPsec, designed with IPv6 in mind, has no concept of...

    Backdoor in upstream xz/liblzma leading to SSH server compromise

    This has got nothing to do with "built it right for FreeBSD." The exploit inserted a blob (key) that made use of the fact that sshd on Linux systems using systemd, needed some way for sshd to be managed by systemd. OpenSSH needed to be linked with systemd libraries, one of which was liblzma...

    ZFS Plan and best practices to migrate from TrueNAS Core to pure FreeBSD

    We don't know. But, opening a PR will get someone with enough ZFS knowledge to look at it. Speculation here will not solve anything. Writing terabytes corrupting a zpool has a smell of serious to me.

    ZFS Plan and best practices to migrate from TrueNAS Core to pure FreeBSD

    If this is a FreeBSD bug, which is unknown at the moment, I don't see how this would resolve anything. We don't have enough information to determine that yet. Writing terabytes to a zpool shouldn't invalidate the pool. The OP may have tickled a bug by writing a lot of output to the zpool. The...

    Look at it first. ps auxww | grep 'zfs send' What do you see in column 8? Does it show a "D"?

    How can l map a command to prtsc-key ?

    For traditional X environments like mwm, CDE, fvwm, and others, one could map the key to execute a shell script that would invoke xwd to capture the screen, writing the output to an arbitrary file of the person's choosing. Then use xwud to either display the output or use some tool to convert it...

    IPF ipf use dhcp/pppoe interface ip in ruleset

    pass in udp keep state is handled by timer. The default UDP timeout is 240 seconds. You can use keep state with other IP protocols. ip_timeout would apply. Though, with IPsec I'd personally use a pass in and a separate pass out rule on the external interface. The real question is, why are...

    Solved Keyboard not working (no response and sending too many characters)

    Does the keyboard work on a raw console? If yes, does it work under a different windowing environment, such as fvwm? Fvwm does not mess around with keyboard mappings. If it works with fvwm then the problem is within the user's windowing environment. Try setting the locale from Belgium to C. If...

    Memory usage on FreeBSD

    Correct. But, top(1) and other tools report swap used. Paging uses swap space. All operating systems except z/OS do this. On z/OS (formerly MVS) paging and swap went to different datasets (mainframe term for files). Swapping involves throwing many data structures defining the process to disk...

    Memory usage on FreeBSD

    Of course RES doesn't include swap. SWAP does. SIZE includes all memory that has been allocated (malloc()ed). malloc()ed memory doesn't necessarily mean it's used. Processes that are swapped out are always the "victims" of memory shortage. Those swapped processes may or may not be the cause. In...

    IPF ipf use dhcp/pppoe interface ip in ruleset

    ipfilter and pf support "first match wins" with the quick keyword. Otherwise both default to "last match wins." I use both. ipfw is like iptables, supporting only "first match wins." Agreed, it doesn't matter which firewall you use, as long as it works. And, as long as one is happy with it...
