http://forums.fedoraforum.org – If I ssh from one host to my new F17 as my unpriveledged account, 9 time out of 10 I get booted out with the following error: >> ssh 192.168.1.144 xxxx@192.168.1.144's password: Last login: Fri Oct 5 14:42:58 2012 from 192.168.1.149 free(846146d) bad block. (memtop = 0x8502000 membot = 0x8458000) Connection to 192.168.1.144 closed. every once in awhile I get in. I get in every time as the root user, so it would seem like a permission thing. Memory is restricted somehow? Not sure if this is sshd or some other part of the login process. I see this in messages: (HowTos)

Stories similar to sshd wierdness in f17

I've tried service sshd restart, I've added sshd:all:allow to my /etc/allow.hosts and the remote user tried rm ~/.ssh/known_hosts. I also checked the logs: cat /var/logs/secure | grep ssh and it says Accepted password for $user from ...

This is the first time this particular user has tried connecting but other users have successfully connected to my machine for several days.

Connection closed [preauth] 18 weeks 20 hours ago

On a Ubuntu 12.04 server, I am getting the following pair of messages in auth.log several times a minute:

Jan 17 22:04:25 binx sshd[14659]: Connection closed by 192.168.0.1 [preauth] Jan 17 22:04:25 binx sshd[14661]: Connection closed by 192.168.0.5 [preauth]

Both those IP addresses belong to separate computers (192.168.0.1 is our firewall/router, 192.168.0.5 is our backup machine), and seem to

I used to login as :ssh root@servip with a password authentication into my centos 6 server.

I am not sure if what I have done has caused this, but while trying to get over my problem of accessing webmin remotely I followed the following tutorial until I reached:

adding auth required pam_google_authenticator.so into /etc/pam.d/sshd. Then by mistake, I have closed the ssh session.

Hopefully you guys can help and see if I've done something weird here, I'm trying to log in with a user I set up, FileZilla shows me:

Command: open "///@///" Command: Pass: ******** Status: Connected to /// Error: Connection closed by server with exitcode 1 Error: Could not connect to server

So, I went into auth.log and I see this:

openldap authentiation 2 years 22 weeks ago

Hi All,

I have configured a ldap server and trying to login to same ldap server using a ldap user.

ssh on QEMU problems [closed] 10 weeks 3 days ago

host: ubuntu guest: distribution based on gentoo embedded

the problem is that after setting up a connection between the host and the guest (via tap interface) I have problems using ssh.

I’m trying to execute the login command but it fails.

As root (via SSH) I get:

root@server:~# login Connection to 192.168.0.50 closed.

The SSH connection is closed.

My system is CentOS 6.3, openldap is configured well, PAM authorization works fine.

But after turning pam_check_host_attr to yes, all LDAP-auths fail with message "Access denied for this host".

hostname on the server returns correct value, the same value is listed in user's profile. "pam_check_host_attr no" works fine and allows everyone with correct uid/password a piece of /var/log/secure:

su - "Sorry." 2 years 45 weeks ago

I just logged in to my remote shell account like I always do: as an ordinary user, because root login is disabled in sshd. Then I may want to become root with the 'su -' command.

But the 'su -' command did not work today. Every time I tried, I got this laconic message: "Sorry."
