What is it for
ALT Linux Rescue is a moderate sized console LiveCD distribution that is designed to help sysadmins fix and repair many kinds of problems with systems they are or feel responsible for; so it comes with tools aiding to:
- perform hardware diagnostics
- resize partitions
- fix bootloaders, partitions, filesystems
- recover partitions and files deleted by accident
- backup and restore to network servers
- deal with optical, tape and file archives
- optimize filesystem usage
- diagnose network problems and remote services
- wipe partitions or drives clean of residual information
- access Android devices, reset Windows passwords, etc
- investigate unauthorized access/security breach events
The resulting media should be bootable on most of the common systems:
- i586 ones starting roughly with Intel Pentium III (256 MB RAM) or equivalent,
- x86_64 ones on any AMD64 compatible hardware with BIOS or UEFI,
- aarch64 ones on any ARMv8 compatible hardware with UEFI.
But above all, don't panic, we've been there too!
|A Regular Build|
Note the tips on suitable utilities to write the hybrid ISO image to bootable media; please do not use UNetbootin, Rufus, or UltraISO as those will cripple the result unfortunately.
Here are some of the packages included to get you started:
- refind to cope with the lack of EFI boot manager menu
- smartmontools for HDD/SSD S.M.A.R.T. monitoring
- testdisk/photorec to recover partitions and data files
- memtest86 for UEFI and memtest86+ for BIOS
- android-tools, bonnie++, chntpw, cpuburn, dc3dd/dcfldd/ddrescue, exfat-utils, gpart, hdparm, ipmitool, lft, netcat, parted, rsync, scalpel, sleuthkit (aff/ewf), uudeview, whdd, wipefreespace...
There's more than a hundred of specialized programs there and many more are available through ALT Linux Sisyphus repository which serves as the base for this rescue image providing it with recent software versions. You can also rebuild it with the tools you need.
Forensic mode boot aims to minimize impact on media by avoiding activation of swap partitions, software RAID and LVM, mounting no filesystems and switching mount-system to readonly mode using loopback devices; press F2 and choose the appropriate option if UEFI booting. This mode enables hardening against rescue root filesystem spoofing.
"Rescue with remote SSH access (DHCP)" might come handy with laggy iKVM as it would bring up networking via DHCP, generate a root password, start SSH server and print the access parameters to the terminal so that only a few IP-KVM keystrokes are required to obtain faster shell. Please do change the password upon login.
