Hello, I have a question about SSH with Kerberos password authentication . Do I receive any host ticket to my client machine when I do ssh connection with Kerberos password authenticaiton? If dont, why? If I login to remote machine through telnet with Kerberos Password authentication [through PAM-kerberos], then I can see the tickets with klist. But with the same setup for sshd, I cannot see

I have a system where 4 or 5 times now it has locked out new ssh connections. It appears as if MaxStartups is not re-allowing connections when the number of unauthenticated connections drops. Instead, 100% rejection until sshd is restarted. The client (even "ssh localhost") gets one of: kex_exchange_identification: Connection closed by remote host kex_exchange_identification:

Hello, This problem is regarding the configuration directive called 'LoginGraceTime'. Problem Description: Tests were done with OpenSSH -3.6.1p2 and 3.7.1p2 on HP-UX. sshd is started with LoginGraceTime as 1 minute.Three windows were used to initiate the ssh client.After launching two clients wait for a sometime without issuing the password so it exceeds the grace period for login.when

I would like some clarification regarding the use of MaxStartups. I have always used the three colon separated value that enables the random drop capabilities, but the documentation for sshd says that MaxStartups can also take a single value which sets a max and leaves random drops off. When I try this, sshd tells me that it got an illegal integer. Looking at the code, in servconf.c it looks

I haven't seen this behaviour and can't replicate it manually using OpenSSH 10.0. I think debugging this will require a log trace with LogLevel=debug3 if you can manage it.

Wonder if you guys could help me out...have a security problem with sshd wich enables a user to do a password login tough the sshd_config states PasswordAuthentication no My config works fine in both gentoo and openbsd 3.3 but users are able to login with tunneled clear text passwords in both 4.9 and 5.1 Im lost.tried everything I can think of. Here is the config:

Hi, I have an auth module for PAM that I wrote a few years ago called pam_vsd.so. The idea is that a user must have a certain privilege before they can successfully authenticate. Without the privilege the PAM module will return PAM_PERM_DENIED. However I find that in OpenSSH 3.7.1p2, I can easily subvert this check simply by hitting return 3 times on connection i.e. [nick at localhost

Help! I am trying to get debug output working with sftp-server, and can''t seem to find the appropriate information to get it working. Yes, I have recompiled sftp-server to include defining DEBUG_SFTP_SERVER. I found that myself in the code before finding it in several postings as the common answer to others having this problem. In addition, I have set up the sshd_config file

We have a system on which users are given a very restricted environment (their shell is a menu) where they should not be able to run arbitrary commands. However, because their shell is not statically linked, ld.so provides a nice clutch of holes for them to exploit. The patch below adds a new configuration option to sshd which quashes their attempts to set LD_PRELOAD etc. using ~/.ssh/environment

Hi, I am not sure this is a bug in Openssh or not. I am running Openssh 4.1p1. with openssl 0.9.7g Scenario: Due to audit enabled on the system, I will need to set Uselogin to yes so that audit will track system call. But when try to login to system with a LDAP user. I get the following. eg: [n113839 at r3ent15pc ~]$ ssh tfstst1 -l ntesting1 ntesting1 at tfstst1's password: Login incorrect

Hi there ! I have an issue with my OpenSSH + PAM configuration on a RedHat Advanced server 2..1 I want to authenticate users connecting to a server using ssh against a radius server. The radius client/server part works ok when I test it with some utilities. I think I have a problem with my ssh which does not pass the username/password to my pam sshd module. I have upgraded to openssh-4.2p1.

Hello I would like to know if there is a keyword in sshd_config that can be used to limit the number of simultaneous connections an OpenSSH server will accept. There is a MaxConnections keyword in SSH2 but I have not found a similar keyword for OpenSSH. Thanks in advance for your response Amba Giri Symbol Technologies, San Jose P: 408-528-2721 E:agiri at sj.symbol.com Symbol. The Enterprise

Hi, we use OpenSSH_3.8.1p1 and we would like to change the complete printer Spool communication from Unix r-Commands to ssh "OpenSSH". Sometimes, we have problems, because of very high connection set-ups in extremely short time intervals, more than 10 open sessions. The connection set-up is partly declined with the error message: ssh_exchange_identification: Connection closed by remote

I'm finding another problem with OpenSSH 2.5.1p1 on RH 6.2 (at least, I think it's the linux box that is the problem). I'm ssh'ing to a RH 6.2 box from a Solaris 7 server (scp also... seems like the same problem). I'm using authorized_keys and identity.pub files to do it automagically, and all works well when it's from user to user, where the username is the same, but if

Hi all, I want to configure Kerberos as the authenticating service for Secure Shell.I am using a Linux machine as the KDC. I have successfully configured the server (Linux machine) as KDC. My client machine is HP-UX Version 11.11. Now when i initialize the client for kerberos by running "kinit" in the HP-UX machine(client), it displays "kinit: Time is out of bounds
