Fixing USB Drive

My old pendrive get corrupted. I've used it to install ArchLinux and needed it repartitioned back as regular pendrive. Unfortunately using "always working" HP USB Disk Storage Format Tool corrupted the drive on my Windows 8.1 box. It just seemed to remove partition table, but drive was not visible on Windows and Drive Manager was unable to format it. Here what I did to recover it (note diskpart was started from elevated command line):

Microsoft Windows [Version 6.3.9600]

 C:\WINDOWS\system32>diskpart

 Microsoft DiskPart version 6.3.9600

 DISKPART> list disk

   Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          465 GB      0 B
  Disk 1    No Media           0 B      0 B
  Disk 2    Online         1908 MB      0 B

 DISKPART> select disk 2

 Disk 2 is now the selected disk.
DISKPART> list partition

   Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Primary           1907 MB    31 KB

 DISKPART> clean
DiskPart succeeded in cleaning the disk.

 DISKPART> list partition

 There are no partitions on this disk to show.

 DISKPART> exit

 Leaving DiskPart...

Now it was enough just to format drive using standard Windows

Hardening OpenWRT - adding non-root user account

I have at home an OpenWRT on TP-Link 1043ND. As I'm most of the time out of my home, I use this for two functions:  - as reliable WiFi Access Point  - as last resort remote access device  - as a box used to wake up other Ethernet enabled devices @ home. As this box is exposed to Internet via IPv6 address, I decided to harden it a little. 1. Adding extra non privileged user account: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install shadow-useradd root@OpenWrt:~# mkdir /home root@OpenWrt:~# useradd -D GROUP=100 HOME=/home INACTIVE=-1 EXPIRE= SHELL= SKEL=/etc/skel CREATE_MAIL_SPOOL=no root@OpenWrt:~# useradd -m -s /bin/ash bart root@OpenWrt:~# cat /etc/passwd root:x:0:0:root:/root:/bin/ash daemon:*:1:1:daemon:/var:/bin/false ftp:*:55:55:ftp:/home/ftp:/bin/false network:*:101:101:network:/var:/bin/false nobody:*:65534:65534:nobody:/var:/bin/false bart:x:1000:1000::/home/bart:/bin/ash root@OpenWrt:~# passwd bart Changing password for bart New passw

Dropbear SSH keys and autossh on OpenWRT

Image
I have a box on Amazon EC2. And I want to have my OpenWRT that is behind IPv4 CGN and have public IPv6 to be reachable from IPv4 Internet. The best idea is to use ssh reverse tunnel connected with autossh to keep connection going. The very first think is to test if I can connect to my Amazon instance from my OpenWRT: root@OpenWrt:~# ssh 54.111.111.111 Host '54.111.111.111' is not in the trusted hosts file. (ssh-rsa fingerprint md5 0f:51:11:11:11:11:11:11:11:11:11:11:11:11:11:11) Do you want to continue connecting? (y/n) y root@54.111.111.111's password: At this point the public key of remote host will be added to .ssh/known_hosts. It is important as we can't have autossh to interact with console in future. root@OpenWrt:~# cat .ssh/known_hosts 2001:1111:1111:1111::1111:1111 ssh-rsa AAAAB3N....... 54.111.111.111 ssh-rsa AAAAB3N.......... Now we need to generate public/private key pair we will be using to connect to our Amazon instance. Invoke fol

SSH Tunel with OpenWRT

You need to install OpenSSH client: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install openssh-client Now OpenSSH client replaced DropBear client: root@OpenWrt:~# ls -l /usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /usr/bin/ssh root@OpenWrt:~# ls -l /rom/usr/bin/ssh lrwxrwxrwx    1 root     root            16 Aug 19  2016 /rom/usr/bin/ssh -> ../sbin/dropbear root@OpenWrt:~# ls -l /overlay/upper/usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /overlay/upper/usr/bin/ssh Can you spot a difference: root@OpenWrt:~# ssh usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]            [-D [bind_address:]port] [-E log_file] [-e escape_char]            [-F configfile] [-I pkcs11] [-i identity_file]            [-J [user@]host[:port]] [-L address] [-l login_name] [-m mac_spec]            [-O ctl_cmd] [-o option] [-p port] [-Q query_option] [-R address]            [-S ctl_path] [-W ho
