similar to: [Bug 3662] New: Make logging of chrooted sftp sessions possible internally routed to local file, without /dev/log device

L.S, I was very happy to find that OpenSSH 2.3.0 now has server support for F-Secure's Win32 FTP client. A problem I have run into a few times (and maybe others before me) is: I want to allow technically unsophisticated users to update their web pages without having to resort to running something like wu-ftpd on my system. SFTPD is a great solution for that since even a casual user can

Hello list. I would like to get your opinion on what is a safe multi-user environment. The scenario: We would like to offer to some customers of ours some sort of network backup/archive. They would put daily or weekly backups from their local machine on our server using rsync and SSH. Therefore, they all have a user account on our server. However, we must ensure that they would absolutely not be

Dear all I'm looking for instructions on how to setup a jailed chroot directory for user which needs to upload via scp to the server. Especially I miss clear instructions about what needs to be in the jailed directory available, like binaries, libraries, etc... Without jail I get it to work, but I want to prevent user downloading for example /etc folder from the server. Does anybody have a

Hi folks, I was thinking about the possibility of separating the OpenSSH transport and authentication functions from the terminal emulation functions, and making it available as a library for other applications to use for secure authenticated transport. My thinking is along the lines of: A whole bunch of applications have implemented "secure" versions of the transport protocol, using

Folks, I've been tasked to find a solution that will create file-transfer-only accounts that are jailed or chrooted to a specific directory. (Not an uncommon task, I think.) Using the OpenSSH server and the OpenSSH scp client program, I can achieve the goal of having a file transfer only account jailed to a specified directory, by using the "scpjail" script (attached) as a

hello Openssh developers, i am administrating a Solaris Network and installed the openssh2.5.2p2 server on one mashine, the clients network-wide. I had a problem with sftp and solved it, but maybe it is at least worth mentioning in the faq: By default, the sftp subsystem is commented out in the sshd_config. Simply removing the comment does not work because the path of the sftpd executable is

Maybe one of you can help. We have set up a CentOS server so that each user who logs in via sftp will be jailed in their home directory. Here's the relevant sshd_config: # override default of no subsystems Subsystem sftp internal-sftp -f LOCAL2 -l INFO Match Group sftponly ChrootDirectory /home/%u ForceCommand internal-sftp This actually works great, but none of

A client wants me to set up a mechanism whereby his customers can drop files securely into directories on his FreeBSD server; he also wants them to be able to retrieve files if needed. The server is already running OpenSSH, and he himself is using Windows clients (TeraTerm and WinSCP) to access it, so the logical thing to do seems to be to have his clients send and receive files via SFTP or SCP.

The sshd server has what I think is a serious flaw. There appears to be no way to turn off remote command execution. (someone please correct me if I am wrong). We have a server which uses a chroot jail, and rbash to severely limit what users can do on our system. The remote command bypasses all of that. ie. ssh user at host cat /etc/passwd will display the password file for the live system

Hello Folks, I'm trying to replace an FTP with several hundred users with something secure. My requirements: - transfers must be logged - users should not have any access to other users' directories - users should land in a writable directory - users should be chrooted I've been trying to get this working with OpenSSH and the internal SFTP server, but it does not

Hi all, I am running Debian Etch. I've compiled openssh-5.0p1 with pam support. I'd like to use a chrooted sftp environment for my users and also log their sftp file transfers. Currently file transfer logging stops working when I implement a jail. Logging from within the chroot seems like a useful feature. I hope it makes it in sooner rather than later. Here's the contents of my

Hello all, I've taken a brief skim of the archives available on theaimsgroup and talked to some others regarding the ideas on chroot SSH/SFTP/SCP functionality. I've also investigated a few of the various patches out for chroot sftp|scp|ssh and am a bit of a loss at finding 'an elegant solution' to the problem. Bearing in mind the excellent starting ground of John Furman's

Good afternoon, I have been using OpenSSH 3.8p1 and added code to sftp-server.c so I could put users in chroot jail. When I setup a new system and downloaded OpenSSH 4.4p1 and tried the same patch it fails with the following in the /var/log/messages file: sftp-server[11001]: fatal: Couldn't chroot to user directory /home/newyork/ftpbcc: Operation not permitted I was wondering why one would

Hi, What is the status on sftp ? People here who are not familiar with "command line ftp" would like to use the new spiffy graphical sftp provided with ssh.com new NT client. As we are planning on replacing all our sshd with openssh, we need sftpd as well. Thanks, Emmanuel -------------- next part -------------- An HTML attachment was scrubbed... URL:
