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:

Hi, I hope this is the right place for a feature request. I'd like to have more flexible AllowUsers/DenyUsers synax. I am in a situation, where I have machines connected to three networks (a private, high speed, a public, and a private vpn) and I'd like to enable root logins only on the private networks. Currently I see no way of doing this, because there is no way to specify a

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

Hello, I have attached a small patch that enables OpenSSH 4.7p1 to use netgroups for users and hosts entries in the AllowUsers and DenyUsers configuration options in sshd_config. This has the following advantages: * hostnames or ip addresses don't have to be maintained in sshd_config, but you can use meaningful names for groups of users and groups of hosts. * large scale installations can

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

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 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

While testing some AllowUsers and AllowGroups combinations I was surprised to find that one cannot be used to override the other. For example: AllowGroups administrators AllowUsers john If john is *not* part of the administrators group, then access is being denied. Is this the expected behaviour? This would force me to create another group just for ssh, something like ssh-admins. This other

Hello all, on website http://sweb.cz/v_t_m/ the Auth selection patch is available. This patch allows to specify AllowUsers, DenyUsers for individual authentications (hostbased, publickey, password, keyboard-interactive, kerberos, kerberos_or_local, gss, securid-1 at ssh.com). By this you can define authentication methods for each user. All configuration options are mentioned in file

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

I want to allow a single host root access via ssh. If the order of processing DenyUsers, AllowUsers were reversed this cold be done in a straight forward manner. My question, is would adding an Apache-like derective Order Deny,Allow violate any standards or be a security problem? _____ Douglas Denault http://www.safeport.com doug at safeport.com

The denyUsers / AllowUsers option in openSSH does not satisfy our needs. We want to supply our own software to allow/deny sessions based on time of day. I do not know if PAM can do this, but in any case we can not use PAM. ? Did someone do such a change in openSSH code

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

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
