similar to: [Bug 1574] New: trailing white space on Forced Command within ChrootDirectory causes failure

Hello, I'm aware of the fact that ChrootDirectory requires that the target directory is root-owned, and I think I've mostly understood why that is necessary, at least within the context of someone who has full shell access. However, I am wondering if that possibility for privilege escalation still exists with a configuration like this: Match Group sftp ForceCommand internal-sftp

Hi all, I am using Match directive and internal-sftp to chroot sftp users into their directory. Connection and login works. I can change directories and put/get files. Also logging of the internal sftp-process works (created a /dev/log socket inside the chroot). As soon as I use the 'ls' command, nothing happens and the the process gets stuck. Listing files does work as soon as I remove

Under "ChrootDirectory" there is a line that says, "This path, and all its components, must be root-owned directories that are not writable by any other user or group." When I first read this "all its components" seemed to mean that all directories and files within this directory must be root owned and root only writable. This seemed odd as I would not be able to

Hi, many people are having problems using SFTP with ChrootDirectory when the jail directory (or the path above) is not owned by root. The question is if chroot'ing to usual home directories can be allowed, even though they are owned by regular users. I know that this topic has been discussed on the list several times now, so I searched the list archives for posts that invalidate the

Hello, I'm trying to set up an sftp (sshfs) service accessible to users with a normal account on a server, but which would be restricted to a subset of the directory hierarchy normally accessible to the users in question, in practice a single directory. The idea would be to allow file access to this directory with a passwordless public key, but keep rest of the users file accessible only with

Hi, (please CC me as I'm not subscribed to the list) If compiled with SELinux support, OpenSSH 4.8 current cvs fails for accounts where the new ChrootDirectory option is active : debug1: PAM: establishing credentials debug3: PAM: opening session debug2: User child is on pid 1695 debug3: mm_request_receive entering debug1: PAM: establishing credentials debug3: safely_chroot: checking

Hello, I've tried many places, finally ending up here to ask my question: why is it so vital that the directory used with the ChrootDirectory directive is root-owned? Like many people I'm trying to use this in a webhosting environment where several users get sftp-only access to some directory, usually something like /home/user/web/part-of-website. I can be sure that there are no setuid

Hey guys, I have read all the messages regarding this issue on the mailing list and I did notice that quite a few people are not exactly happy with the new easiness of the chroot support introduced to openssh. I'm one of them and I think to support my special configuration, the implementation would need to be changed. I'm right now setting up a small web hosting company an every

Hi All I am a novice LLVM user trying to use LLVMConstIntOfString using the c api to get a integer of arbitrary size from a hexadecimal string. Example code follows: LLVMContextRef context = LLVMContextCreate(); LLVMValueRef value = LLVMConstIntOfString(LLVMInt64TypeInContext(context), "0x0000000f0000ffff", 16); This is working properly as expected. However I have noticed that

Hi, According to the sshd_config manual page the option ChrootDirectory can be used to force a chroot:ed environment for the SSHD server. But as I understand the manual page this is a global setting and it is not possible to specify this per SSH subsystem. We are building a system where we need users to be able to log on from remote machines via SSH, but with the tweaks that we (for security

Hi I'm using Centos 5 with Openssh-5.0p1 installed (and OpenSSL 0.98b and Zlib 1.2.3-3). I've managed to get a chroot'd SFTP session using ChrootDirectory and the new built-in SFTP subsystem. However, when I use SSH to connect to the same account the session hangs rather than closing the connection. This happens whether or not I use /sbin/nologin /bin/false or even /bin/sh

Hello, I would like to know how would I go about in using a connection type variable with the sshd_config. What would be the consequences,security,problem with doing such a thing. What I would like to accomplish is something like: Match Group Users ChrootDirectory "sftp/ssh" /home/%u ForceCommand "sftp/ssh" internal-sftp AllowTcpForwarding "sftp/ssh" no Where

Hi, This is either a query or a feature request. I have a system where sftp users are chrooted using scponly, which while requiring much more setup than OpenSSH's internal-sftp method, has the useful feature of allowing an initial chroot to a subdirectory, typically the one used for file exchange. I've searched for a way to do the same thing with OpenSSH. So far haven't found it. If
