0 file resync restore, skipped 69168 blocks expected. Поначалу, я вооружился man’ом по комманде dump, и смело выполнял бэкап в файл следующим способом:.

The other file systems should be set to values greater than one. If more than one file system has the same passno, fsck (8) will attempt to check file systems in parallel if possible. File systems that should be skipped should have their passno set to zero. The root file system needs to be checked before everything else and should have its passno set to one. Determines the order in which file systems should be checked.

Once new disk added, create a temporary mount point to mount your /dev/ad6s1, enter:
# mkdir /newuser
Reboot and drop system to a signal user mode to migrate to a new disk:
# reboot
At boot prompt type:
# boot -s
Mount all file systems:
# mount -a -t ufs
Mount new /newuser file system:
# mount /dev/ad6s1 /newuser
Copy old /usr to /newuser:
# cd /newuser # dump 0af – /usr | restore rf –
Sample outputs:

Open /etc/fstab, enter:
# vi /etc/fstab
Modify /usr entry to point to a new location:.

Mount -a -t ufs. Copy old /usr to /newuser: # cd /newuser # dump 0af – /usr . Mount new /newuser file system: # mount /dev/ad6s1 /newuser.

Linux supports many filesystem types. For example, to mount an MS-DOS floppy, you could use the following command: $ mount -t msdos /dev/fd0 /floppy $. Mount tries to guess the type of the filesystem. You can also use the -t fstype option to specify the type directly; this is sometimes necessary, since the heuristics mount uses do not always work.

A collection of Unix/Linux/BSD commands and tasks which are useful for IT work or for advanced users.

Ext2 reserves some blocks for root so that if the filesystem fills up, it is still possible to do system administration without having to delete anything. However, for floppies there is no point in reserving any blocks. The reserved amount is by default 5 percent, which on most disks isn’t enough to be wasteful. Number of blocks reserved for root.

My Nextcloud instance is externally accessible, and yet if someone were to get inside my Jail, I could rest easy knowing they still didn’t have access to the rest of my host server. I chronicled the setup process including jail setup using iocage, https with Lets Encrypt, and full setup of the web stack. I configured Nextcloud 12 inside a FreeBSD jail in order to allow me access to files i might need while at University. I figured this would be a optimal solution for files that I might need access to unexpectedly, on computers where I am not in complete control.

Some GUI related issues are also host specific. Is the problem specific to a certain host OS. Problems are usually not host OS specific (because most of the VirtualBox code base is shared across all supported platforms), but especially in the areas of networking and USB support, there are significant differences between host platforms.

    In other words, if someone wanted to take a network off the air, he could do it either by taking the network off the air, or by taking the networks it connects to off the air, ad infinitum. If you are considering using Internet for a service which is absolutely time or mission critical, you should consider your fallback position in the event that the network is down or damaged. The reason has to do with the distributed nature of the network: every network node is connected via other networks which in turn connect to other networks, etc. An attacker can always disrupt a connection “upstream” from where the victim controls it. There are many, many, ways someone can deny service, ranging from the complex to the trivial brute-force. Denial of service is when someone decides to make your network or firewall useless by disrupting it, crashing it, jamming it, or flooding it. A firewall administrator or ISP only has control of a few of the local elements within reach. The problem with denial of service on the Internet is that it is impossible to prevent.

    In order for a directory to become the root directory a process must have execute (search) access for that directory. It should be noted that chroot() has no effect on the process's . The chroot() system call causes dirname to become the root directory, that is, the starting point for path searches of pathnames beginning with `/'.
