Hi Team, I am just a curious individual user who reviewed the OpenSSH;not working for a company. I was just wondering why there is a restriction for chroot directory to be owned by root. The line of code below in session.c show them. The basic UNIX security permissions provide a sufficient access control. Have you guys found a way to bypass security if the directory is not owned by root? -

Hi all, Today, I was tasked at work with setting up a chroot SFTP server on a 64bit Arch Linux server. I naturally turned to Arch Linux's wiki article on the subject (http://wiki.archlinux.org/index.php/SFTP-chroot) and the directions were very clear. However, the directions did not work. I kept getting a "Write failed: Broken pipe" error after attempting to connect. Upon digging

Hello I tried to install an old version of autocad (13, student edition, Release 13c4a), on a MSWindows-free box. I ran : $ wine d:\setup32.exe It begun all right, I had the installation screens, then it failed with the following messages : err:win:WIN_FindWndPtr window 10029 belongs to other process err:win:WIN_FindWndPtr window 10021 belongs to other process err:win:WIN_FindWndPtr window

...k to the external /bin/su, construct your own /etc/passwd and so on, and thereby gain root inside the chroot. Chroots are easily escapable by root (e.g. https://filippo.io/escaping-a-chroot-jail-slash-1/). The particular case Jakub is referring to is: https://bugzilla.redhat.com/show_bug.cgi?id=522141 https://lists.mindrot.org/pipermail/openssh-unix-dev/2008-November/026981.html has some recommendations for making the default directory that users start in be writable in a less dangerous way. -- Colin Watson [cjwatson at debian.org]

Note: I am digest subscriber so if you could copy me directly on any reply to the list I would appreciate it very much. I sent this to the OpenSSH list (secureshell at securityfocus.com) yesterday and received no response so I am asking here in hopes that someone else has run across this problem on CentOS. We have encountered a situation that requires sftp access to one of our server by an

Hi, I configured openssh 5.1p1 for sftp server. Here the specifications in sshd_config file: Subsystem sftp internal-sftp Match Group sftp ForceCommand internal-sftp ChrootDirectory /home/%u AllowTcpForwarding no When a user is logged in, he can't upload his document and he receives this message: carlo at Music:~$ sftp user at 213.217.147.123 Connecting to

Hello, I am trying to setup a file server using the SFTP protocol with OpenSSH. I am in trouble because sshd refuses to chroot to a directory that is writable by users other than the owner. I guess that this is to prevent someone else from creating a .ssh/authorized_keys file and impersonate the user. But we have configured an alternative AuthorizedKeysFile. I also understand that a chroot user
