Hello, My computer has 2 x 4GB memory, as one can see in dmesg. A part of it is used by the video card, I'm not sure how much, maybe around 256MB or less I want to know if I will hit the swap space when I will let it run on 1 x 4GB memory, but I'm not sure how to interpret some of the following

Recently a machine running OpenBSD 6.8 had its configuration changed and I believe it to have been subject to a malicious attack. This change is completely unexplainable, compromised security, and would have required root access. The log files reveal nothing out of the ordinary except for

So you want to ktrace your entire system, with a limited set of monitors. I've played with this before, to identify specific behaviours when developing pledge. It required a large number of hacks, and the performance was dismal. Based upon my experience, I predict it will not work for your

packet filter question

Hi folks, if it is allowed to ask a question about packet filter here? Please take a look at the attached pf.conf file. Problem is that incoming traffic from a host in (internal:network) to an external host port is passed in rule 86 (thats one of the debproxy lines) pass $log0 quick

Hi all, We need an advice for our e-mail traffic with openbsd.org When I sent an e-mail to openbsd.org which is rhs, from 160.75.0.0/16, I got a TLS handshake error. On the other hand, when I tried from another subnet, there was no problem. Nevertheless, our mta has not a problem like this
