Hi, I want to backup my system via rsync over ssh, but login is *not* permited! According to the sshd_config man page, I need to set PermitRootLogin to forced-commands-only. In order to run follow command, how to set command option in authorized_keys? # rsync -avz server:/etc /backup Best Regards!

Hi, all: I want to check small files' property(such as date, path, and so on) frequently. The files are stored in netwrok driver and their sizes vary from 2KB to 5KB. I found that Windows 2K outperform Linux/Samba very much after I campared the bench results. I am very confused about it and who can explain it? The computers' configurations are as follows: 1.

When use rsync with daemon mode, rsync can call chroot. But with ssh mode, is it possible to use chroot? Thanks very much! Best Regards! Jacky Kim .

When I ssh-keygen a passwordless key pair for root and give the public key to openssh server(sshsrv), then it is ok to # ssh root@sshsrv But when I generate a password key pair for root and give the public key to openssh server(sshsrv), then I fail to # echo "rootpasswd" | ssh root@sshsrv and get the follow message: Pseudo-terminal will not be allocated because stdin is not a

When use rsync with daemon mode, how to permit user from using rsync via remote shell mode? Thanks very much! Best Regards! Jacky Kim .

Hello, Still busy with details... Considering, as in my previous example, a password_query returning '!' or NULL for the "nologin" column, depending on an account's status (suspended or not). Let's consider a suspended user "some.user". In the case of a successful authentication, one has: sh-3.2# doveadm auth test some.user goodpassword; echo $? passdb:

I am running Dovecot with system users (userdb passwd), but some of those users don't have shell accounts on the IMAP server so their shell on that machine is set to /usr/sbin/nologin. Currently I am using maildirs and this is not a problem, but I am in the process of switching to dbox which means I will need a cronjob running 'doveadm purge -A'. During testing I found that those

hi, the man page for sshd(1) says about /etc/nologin: "The file should be world-readable". However, nologin has no effect if it's not readable by the connecting user: if (pw->pw_uid) f = fopen(_PATH_NOLOGIN, "r"); if (f) { /* /etc/nologin exists. Print its contents and exit. */ ... ... return(254) if root has a

I notice that the nologin parameter for the AUTH command is gone in version 1.1 of Dovecot Authentication Protocol. nologin was added in 1.1, so that authentication client could indicate that there will be no subsequent master requests to retrieve user info. Could we have nologin back please? Kirill

My apologies if this has already been discussed. I looked through the mailing list archives and couldn't see any mention of this problem. I compiled and installed openssh-2.3.0p1 on a sparc running SunOS 5.7, and while I was testing it to make sure everything was working properly, I noticed that when I used PAM to authenticate, rather than /bin/login, sshd was not honoring /etc/nologin. I

Hi developers, today I tried to disable logins to an ssh server by putting a nologin file into /etc. This only worked for logins that use the password authentication mechanism. publickey-based authentications still succeeded and the users were allowed into the system. This seems straightforward to me since openssh 4.3 disabled the evaluation of /etc/nologin in favour of pam_nologin but

Hi at all, in our test environment, I'm playing with dovecot 2.1.13 configured as imap/pop/managesieve proxy. It is configured to authenticate users with ldap and it works very well. Now, I'd like to temporary disable some users's login, because we are moving to another storage, and I wouldn't stop imap service at all. I've found on Dovecot wiki that I could use

Hi, Just found out that Postfix does not implement/support the AUTH=sender parameter. So, back to Dovecot, can we use variables in the submission_relay_user = submission_relay_password = then Dovecot will forward the username and password information of the current user to the Postfix submission service for authentication?

Hello everyone, I noticed recently that when I had /etc/nologin in place on my server I couldn't log in when I authenticated via passwords, but when I used RSA authentication I was able to log in no problem. I looked through the source, and I think I might see where the problem is. I have a Linux system, so sshd was compiled with PAM support. Using normal authentication, the pam_nologin
