similar to: internal-sftp stuck on 'ls' with chrootdirectory

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

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

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

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

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, 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

What is the intended behavior of the internal-sftp server when looking to resolve identity information for user via the nsswitch configured mechanisms? I am seeing different behavior between two packaged versions and am looking to understand what should be expected. Scenario: Utilizing a developed directory services plugin (dsplug), "ls" access on the sftp session fails with 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 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

Hi all, I am using a 'tricked' Cox Hazard regression model for discrete choice habitat modelling. However, I'm having a hard time understanding the meaning of the first line the following part of the summary() output: Rsquare= 0.307 (max possible= 0.475 ) Likelihood ratio test= 91.8 on 12 df, p=2.23e-14 Wald test = 26.3 on 12 df, p=0.00977 Score (logrank) test = 58.6 on 12 df,

Hi all, I wish to do build discrete choice model to analyse habitat selection of wolverines. This can be done with a 'tricked' stratified Cox proportional hazard model. For each individual animal each selected position, and possible alternative non-used available positions are combined into strata. This means that one stratum contains a set of 1 used position and several positions which

Hi, I change the dovecot.conf default_mail_env = mbox:/Mail/IMAP/%u/:INBOX=/var/mail/%u After I did the change, I restart dovecot with the hope that folder that I create will be stored in /Mail/IMAP/%u. Then I use Mozzila as my email client and change the IMAP server directory to ~nina/IMAP/ which is the link to /Mail/IMAP/nina/. But then I can not create folder anymore from Mozzila, or view
