similar to: MAX_ALLOW_USERS

Hello! We have the server with RHEL 5.5 (64-bit) and need to connect many parallel users over ssh (OpenSSH). Usually we use openssh-4.4p1, builded from the sources with changed "servconf.h" file by this type: ???#define MAX_ALLOW_USERS ????????10000 ????/* Max # users on allow list. */ ???#define MAX_DENY_USERS ???????????10000 ????/* Max # users on deny list. */ ???#define

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

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

Is it possible to use encryption only for authenticate and then switch to no encryption? I've looked at the code for OpenSSH 3.5p1, cipher.c, and it looks like the answer is no, at least for protocol 1. However, I cannot tell if that is a deliberate design limitation of the implementation or if it is inherent in ssh protocol 2. My dilemma is a customer who wants to use their network IDS

On Solaris 8, I have ssh 3.1.0 and on other box Sol 7 I have 1.2.26 (min version for comtable with ssh 3), I checked also /etc/ssh2/sshd2_config file ## SSH1 compatibility # Ssh1Compatibility <set by configure by default> # Sshd1Path <set by configure by default 2) generate key for ssh3 # ssh-keygen2 -P /etc/ssh2/hostkey

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

Hi, I'm trying to use pam_listfile.so to deny logins from all others but few users (names in /etc/loginusers). With password authentication it works fine, but with public key authentication OpenSSH lets in users whose names arent't in /etc/loginusers. AllowUsers in sshd_config does what one would expect. I'm using OpenSSH-3.0.2p1 on Debian testing (package version 1:3.0.2p1-6)

Hi all, I'd like to know if it's possible to add a custom field when the authentification is made by users. My boolean custom field will be for example "AllowUser" (false/true). I'm trying to do something like that but it's not working : /user_filter = (&(objectClass=posixAccount)(uid=%u)(objectClass=myclass)(AllowUser=TRUE))/ This is my dovecot/ldap

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 Michael, Just noticed you are using auth_bind_userdn which we don't. I think you may need to use pass_filter rather than user_filter?? Best Regards Martin On 2017-06-07 10:59, Martin Wheldon wrote: > Hi Michael, > > We do exactly that see example below: > > user_filter = >

Aloha Jiwen (I used to get kama'aina discounts, but no longer)-- First, you didn't tell us what OpenSSH source code version you're trying to compile. Without that info there are any number of possible problems--so I'll assume (for now) that you're using the latest released portable version of OpenSSH. Please reply with specific version info. The fact that things are blowing

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

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

Hi! I'm experimenting with migrating the custom sshd_config settings for our (Debian bullseye, openssh-server 8.4) server environment into fragments under sshd_config.d/, and am wondering about sshd's behaviour when encountering multiple AllowGroup lines. The manual states "For each keyword, the first obtained value will be used.", so that gives me the impression that any

Crap. I hit send too fast. Last sentence in first paragraph should have read "no completely secure way" for authentication to be passed-- because the agent-based forwarding program could have been compromised as well--except for the cases already mentioned such as SRP and RSAAuth where the auth. information is better protected. Even if the SF server had been capable of forwarding the

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
