OK, sorry for unclear previous message. In the past, one man teached me the FreeBSD basics and also installed my gateway. In that time, I was not able to install and setup FreeBSD by myself. He left there some holes - e.g. open virtual consoles, unset firewall, etc. As the time went, I learned a lot about Unixes and FreeBSD and I tried to setup my own firewall, install and setup some programs (with big help of this and Questions lists, manpages and other books). When I tried to setup more security on that system, except other things, I disabled all virtual tty's, because there is no need to connect to this machine remotelly (it's located 5 steps from my desk). In the past, that man connected to my system remotely from various IPs. Now, when I cat /var/log/lastlog, in the very bottom of the file, I can read some connects from remote machines to ttyp0 and ttyp1. It's impossible for me to retrieve connection dates from that file. Of course, I read man last, man wtmp, etc., but there is nothing about /var/log/lastlog file. May be, that lines was added in the deep past, when the machine was open. But may be, it was done in few previous days... I know, if my machine was compromised, it is impossible to believe in anything on that machine (also kernel, sources). So, are there some other ways to get information about connection dates? Peter Rosahome | help
