I’m running FreeBSD on my beaglebone black headless server and everything looks perfect, however, after some time idle (no user interaction) it stops responding to any incoming connection (ssh/http) but if I ping it, I get an answer back.



It was not accepting ssh or http connections, I’ve used an app called Fing to ping the BBB and it responded the pings but nothing else was responding. I tried the Wake on LAN function and it started to respond ssh and http. Coincidence or not, I was experiencing these “hangs” everyday, several times a day, after the WoL the BBB is up and running for 3 days now. I didn’t restart the BBB. I had a look on dmesg to see if there is any apm running and nothing, /var/log/messages doesn’t give me any clue, looks like nothing happened. The BBB is wired straight to my router and the IP address is locked/reserved to its MAC address.



Tried to check apm status but apm is not installed.

Also tried to install apm but no success.

Tried to check if there is any kernel module loaded (kldstat) to manage power, but it doesn’t look like the case:



kldstat



Did anyone face a similar issue, or know if there is any way to prevent FreeBSD to “sleep”, or have a clue of what is happening?

  • Append /usr/local/sbin:/usr/sbin:/sbin to your PATH, and edit the then answer to M. Ribeiro's query into your question.

  • A wild guess: your NIC enters a power saving state. This problem comes up every once in a while across different machines and OSes.

    So maybe the problem was fixed for Linux, for that particular NIC?

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
