similar to: AllowUsers and AllogGroups problem...

Markus, ignore the other stuff I sent.. I need to go back to bed and stop trying to code.. <sigh> For everone else.. Will this make everyone happy? This does the follow. it will always honor AllowUsers. If there is no Allow/DenyGroups it stated they are not in allowUsers. IF there are AllowDenyGroups it tries them. And then stated they are not in either AllowUsers nor AllowGroups

A short while ago, I looked at using the AllowUsers configuration option in openssh (v3.8p1 , but I believe this to be unchanged in 3.9p1) to restrict access such that only specific remote machines could access specific local accounts. I swiftly discovered that a) specifying wildcarded IP numbers to try to allow a useful IP range was pointless: if I specified AllowUsers joe at

I added a few features to openssh for my local use that I think would be more broadly useful. I basically added access control lists to control who would be allowed public key authentication. I added four config file entries for the server: PubkeyAllowUsers PubkeyDenyUsers PubkeyAllowGroups PubkeyDenyGroups These follow the same sematics as the already existing entries for

The primary purpose of the attached patches is for portable OpenSSH to support changing expired passwords as specified in shadow password files. To support that, I did a couple enhancements to the base OpenBSD OpenSSH code. They are: 1. Consolidated the handling of "forced_command" into a do_exec() function in session.c. These were being handled inconsistently and allocated

This is a port of a patch I contributed to ssh 1.2.23 in May 1998. I have missed the functionality after moving to OpenSSH so I have updated the patch and hope OpenSSH might accept it. The patch allows sshd_config to have lines like: AllowUsers root at localhost AllowUsers tridge@* AllowUsers guest at 192.168.2.* DenyUsers badguy@* etc. I found this useful for restricting users to only login

Hey, After discussing the limit of MAX_ALLOW_USERS I've been trying to use AllowGroups instead. In the config file I have the AllowUsers lines before the AllowGroups lines (I have tried both ways) and it appears that the presence on the AllowGroups directives seems to blow away any Allow* directives I have set. I'm not sure how to check further for bugs so I figured I'd contact

I do not know have you have already fixed problem when both AllowUsers and AllowGroups have been defined. Source package was: openssh-2.1.1-p1 (rpm version) Problem is described in this example: AllowGroups admins ssh AllowUsers testuser testusers primary group is users User cannot login because his primary group wasn't admins or ssh... I have included patch for this in this message. Hope

Hello, whereas most people take passwd/shadow/ldap/<whatever> as the place where decision on a chrooted environment / sandbox for certain users is met (just set the given usershell appropriateley), I needed a somewhat different approach. Below is a tiny patch to 2.2.0p1 which enhances the sshd-config by two options and, when set, places all users / users of a certain group immediately in

Hi, I ran across a case in which my server maintenance was simplified by using SSHD configuration options like this in sshd_config: AllowGroups admin at 192.168.0.* sshuser in much the same fashion as (Allow|Deny)Users. In this case, the goal is to provide access to administrators only from the local network, while allowing SSH users to login from anywhere. This (IMHO) simplifies access

Hi. Whenever I notice a typo someplace, I fix it in a local "typo tree". Attached is 2 patches from that tree, one against OpenBSD and the other against Portable. Is it worth fixing these? -Daz. -- Darren Tucker (dtucker at zip.com.au) GPG key 8FF4FA69 / D9A3 86E9 7EEE AF4B B2D4 37C9 C982 80C7 8FF4 FA69 Good judgement comes with experience.

The following is a patch I've been working on to support a "ChrootUser" option in the sshd_config file. I was looking for a way to offer sftp access and at the same time restict interactive shell access. This patch is a necessary first step (IMO). It applies clean with 'patch -l'. Also attached is a shell script that helps to build a chrooted home dir on a RedHat 7.2

Hey everyone, After discussing the AllowGroups I think I've discovered a bug. The system is a solaris 8 system and the problem is that when I use AllowGroups with no AllowUsers args, the proper actions happen. Same with AllowUsers and no AllowGroups. When I try to combine the two, none of the Allow directives seem to take. Is it just me or maybe a bug? -James

Hi list! I have some machines running openssh 3.9p1. AllowUsers is set to my users, that are allowed to login. If I set PermitRoot without-password, but do not include root in AllowUsers, root is not able to login with pubkey. I do not want to set root in AllowUsers, since the without-password option should check this allready, I think... So I made a small patch that allows me to login as root

It seems the syntax for AllowUsers in sshd_config is not the same that is given in man sshd_config and in several documentation on the web. (http://www.openssh.com/cgi-bin/man.cgi?query=sshd_config) e.g. AllowUsers root does work. AllowUsers root username does not work. If I try to login as root I get "User root from <hostname> not allowed because not listed in AllowUsers".

Hi there, I have just compiled openssh-5.0 on Solaris 10, and am trying to set up a certain pattern of user access control. Essentially, regular users should be able to login from any network, while root should be able to login only from a private network 192.168.88.0/22. Actually, for the purpose of sshd_config, this is four networks, but that's another story... Here is what I tried:

What I was trying to do: I wanted to use the AllowGroups facility to allow users in by group instead of listing individual usernames but also allow root only from a single central host. Setup actions: targetusername on target host has a secondary group entry of "staff". Updated sshd_config to add the lines: AllowUsers root at nimsrvr AllowGroups staff targertusername is NOT

Hi, I've just been adding a few extra hosts to my sshd_config's AllowUsers, and it's got a bit unwieldy. As far as I can tell from the sshd_config(5) and ssh_config(5) man pages, the *only* way to specify multiple AllowUsers patterns is on a single line, separated by spaces. With more than 6 or 7 patterns it starts wrapping on to multiple lines and gets hard to read, especially

OpenSSH 3.0 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. This release contains many portability bug-fixes (listed in the ChangeLog) as well as several new features (listed below). We would like to thank the

I smacked into this previously reported bug today whereby an invalid keyword in the Match{} stanza did not throw an error on configuration reload. Are there any plans to fix this? Likewise the penchant for some fields to be comma separated and others to be spaces is just asking for mistakes. Why not support both and be done with it? There was no response (that I saw in the archives) to this post

I have a number of development machines behind my OpenBSD firewall which all provide a very permissive development account (and easy sudo). I don't want this account exposed on the internet side of the firewall, so I created a doorstep account with no perms and really long passwords to get anywhere useful. I looked through the SSH book and it gave me the impression that I could set up these
