In case you need to perform re-installation of OpenSSH on the server with OS FreeBSD and cPanel you may do it by installing it from the ports. Just do the following:

Code: Select all

ln -s /etc/rc.d/ /usr/etc/rc.d
cd /usr/ports/security/openssh-portable
make PREFIX=/usr ETCSSH=/etc/ssh install


To trace the work of the SSH daemon you may run in console of the server:

Code: Select all

/usr/sbin/sshd -ddd -p 65535

After that you will need to connect to the server using port ...

For this example /dev/ad0 is the hard drive where the live system is running.

The target is an USB flash stick /dev/da0.

The following is the sequence of commands used:

Collect live file system sizes and save

Code: Select all

df -h > liveFSsizes

cat liveFSsizes

Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s1a 496M 169M 287M 37% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/ad0s1d 1.5G 26M 1.4G 2% /var
/dev/ad0s1e 496M 10K 456M 0% /tmp

If you intend to check whether all library dependencies are satisfied or not, you might be interested in the pkg_libchk utility from sysutils/bsdadminscripts.

If you mean "which port depends on which ports", either run pkg_info -rR <portglob> for an installed port, or run make build-depends-list && make run-depends-list in a port directory under /usr/ports.

Finally: if you wonder which dependencies you still need to install for a port, run make missing in a port directory ...

nextboot -- specify an alternate kernel and boot flags for the next reboot

SYNOPSIS

nextboot -k kernel
nextboot -D

DESCRIPTION

The nextboot utility allows specifying an alternate kernel and/or boot
flags for the next time the machine is booted. Once the loader(8) loads
in the new kernel information, it is deleted so in case the new kernel
hangs the machine, once it is rebooted, the machine will automatically
revert to its previous ...

** FreeBSD local r00t 0day
Discovered & Exploited by Nikolaos Rangos also known as Kingcope.

"Go fetch your FreeBSD r00tkitz" // http://www.youtube.com/watch?v=dDnhthI27Fg

There is an unbelievable simple local r00t bug in recent FreeBSD versions.
I audited FreeBSD for local r00t bugs a long time *sigh*. Now it pays out.

The bug resides in the Run-Time Link-Editor (rtld).

IF under the "Bandwidth" section in the cPanel user-interface (http://cpanel_server.com:2082/frontend/ ... width.html) you can not see the details of the months and days (only blank fields), most likely the issue connected with improper GD/Fonts work.

The real reason is "incorrect" (from cPanel point of view) fonts location. Following symbolic link resolves it:

Code: Select all

ln -s /usr/local/lib/X11/fonts/URW /usr/share/fonts

On FreeBSD server with cPanel control panel Exim restart lead us to the following errors:

Code: Select all

This error may be caused by recent cpanel upgrade (upcp) and other 'perl-involved' maintenance on the server. First part of error message can be fixed by installing CPAN modules manually: ...
