OpenSUSE :: Root Login - Attempts To Start Missing App?
Oct 15, 2010
Somehow an app on this box seems to have disappeared long ago which was configured to start immediatedly with a root login (eg su). Now, whenever upgrading permissions to root or logging (and assuming login as root), an error displays saying "cannot find <application>"
Considering root usually is different than other logins, am not sure where to start looking on an OpenSuSE box. I've tried without success
BASH -v to enable verbose mode before executing a "su."
BASH --debugger to enable debugging mode before executing a "su."
Logout, Login as root and inspect /var/log/ hoping to find some logfile that audits the login sequence, but may be looking at a wrong logfile.

Yesterday I applied the su security patch to my openSuSE 11.2 x86_64 system.After applying the patch, any attempt at su failed, and after rebooting the system earlier this morning any login (root, user, otherwise) fails with a "Permission Denied".Is it possible that the su update somehow messed up my (standard) pam settings?

For about a week now I've been seeing mass attempts to relay through postfix and login to dovecot from the same 2 addresses, none are successful due to how postfix/dovecot are configured and I wouldn't be overly worried but my isp have picked up on it and are nagging at me
What ways do people go about just dropping connection attempts from offending addresses/ranges when stuff like that happens? An ideal thing would be something that detects repeated failed attempts from a host or range and subsequently ignore/ban them, perhaps for a specified length of time, something along the lines of denyhosts and fail2ban for ssh would be great Don't know if there's anything out there or just a plain tried and trusted method anyone might use for stuff like this, if not a hint on the most appropriate way to go about it 'manually' would do

I cannot login with root. some time ago, had to make some changes to shadow password file. Cannot log in. Booted into single user mode. typed in passwd root. Get Access token error. I read if the shadow password for root is messed up, would need to delete it and leave it blank OR use pwconv to start a new shadow password file, then do a passwd root to create a new password. pwconv is not installed. Where do I download it for centos?

How do I limit the max login attempts in the sshd_config file? I found a way to do it on Google some time back but I can't find it now. I have Denyhost already, but I really wanna do the "MAx Login Attempts" what ever it was that I was able to do in the config file.

I know this is probably easy and if I only took a while to figure it out maybe I could but I have some stuff that needs to happen soon and I can't figure this out. I was wondering how I could have a log monitor that would email me whenever someone tries to login over ssh to my system. I'm open to everything daemons/scripts or cron itl works as I am not running a production server (but I might be starting that soon). Oh and just a side how do I get sent an email when I get port scanned

I have a server box behind my ISP router at home, and I need to allow ssh access to my server. My ISP router doesn't let me allow selectively ssh from some IP. It allows ssh to everyone.
I have fedora10 and openssh-server-5.1p1-3. How can I configure openssh to allow just from 1 IP?
Does it use xinetd at all and the hosts.allow and .deny mechanism?

I have an SSH server on my laptop, and I'm using the default configuration file, but I added "AllowUsers <myUserName>". I get lots of login attempts like the ones below in my /var/log/auth.log.From Google, I find that pam_winbind allows some kind of Windows authentication. This leaves me with 2 questions. What does winbind do when I have not configured any Windows/Samba accounts? How can I turn it off?
Code:
Oct 23 20:01:49 muon sshd[24329]: User root from 201.116.17.163 not allowed because not listed in AllowUsers

I am running a ubuntu server 10.10 with SSH, and OpenVPN. I use it mainly for the VPN, but I have seen log in attempts such as:
Mar 22 14:52:53 UbuntuSvr sshd[2397]: Invalid user support from 85.217.190.69
Mar 22 14:52:55 UbuntuSvr sshd[2399]: Invalid user student from 85.217.190.69
Mar 22 14:52:57 UbuntuSvr sshd[2401]: Invalid user transfer from 85.217.190.69
Mar 22 14:52:59 UbuntuSvr sshd[2403]: Invalid user user from 85.217.190.69
[Code]...
Is it possible to make it so when some one has tried logging in 5 times with an invalid user/pass that the ip is banned for 10 minutes? I have password auth set to no and am using keys.

I think someone has been in my apartment when I'm at work and attempted to login to my computer.
Rather than searching through all the logs, is there any way for Conky to display the last 2 or 3 login attempts?

I'm trying to learn Linux by myself and i have a list of projects. for this project i have to use the grep command to show all failed login's attempts in my machine.
I believe the attempts are saved at /var/share/messages.log but i cannot figure it out.

I'm trying to lock an account after a number of failed login attempts in a RHEL5.
This is the relevant configuration in /etc/pam.d/system-auth
In the logs I can see how the count of failed logins increase and exceeds my deny option but the account isn't locked
Do I need any other option in the PAM file? Is there any other way to lock an account?

I'd like to limit login attempts for specific user. I've found information in manpages: [URL]but I'm not sure if this '@' is purposly there, so would be that correct?
Code:
aparaho - maxlogins 4
or
Code:
@aparaho - maxlogins 4
Maybe '@' is a group syntax? I'm confused.
What happens after 4 failed loggins? Is it enough to restart system to get another login attempts?
Are there any other values that it is reasonable to limit for safety reasons?

I am trying to get OpenLDAP to authenticate user logins, but running around in circles. Are there any logs produced by either client and/or server that would indicate possible reasons why it was unable to login as a user?Below is an explanation, any ideas would be appreciated, as I think everything is setup as per the various articles on using LDAP.
I have a CentOS 5.5 OpenLDAP server, and several others, some host services, some are file shares (samba).So far I have been able to successfully configure OpenLDAP to carry out all the ldap* commands from both the local server and from any of the remote servers, either via non-ssl or ssl connections. However, as soon as I try connecting any services up to it, it doesn't play ball.Back to basics, having cleared off all previous attempts at this from all machines, I have gone through the following:
Installed OpenLDAP server/client on host (plus nss_ldap).
Configured /etc/openldap/slapd.conf (see below)
Configured /etc/openldap/ldap.conf (see below)

A couple of weeks ago I installed openSUSE 11.3/KDE 4.4.4 over openSUSE 11.0/KDE 3.5. It went well except for what turned out to be a glitch with the KDE default Plasma Desktop Workspace, which prevented the system from shutting down (the screen would go blank and then nothing would happen). Changing the Activity in the Desktop Settings to Folder View got rid of the glitch, returning everything to normal.
The printer icon/widget is now a question mark "?." I can't say for certain when this happened.Clicking on the widget produces the message, "KDEint could not launch 'opt/kde3/bin/startprint'."The command for the widget is 'opt/kde3/bin/startprint %U'.The file opt/kde3/bin/startprint no longer exists.What additional information, if any, might be needed, and what can be done to get this widget working again?

I have found this link "Login Failed" message when logging in through RDP
I am suffering from exactly these symptoms. Can anyone suggest what the likely cause is? How would that bug/solution relate to my environment: openSUSE 11.3/xrdp 0.4.1-85.1?
And lastly, how can I find out if the update implied under "Additional Information" has happened?

I cannot see what the problem is here. I have installed MySQL 5.1.36 via YaST on my openSUSE 11.2 (32-bit) system.I can log in as root. I can "create user MY_user identified by 'my_passwd';" and a new user is created. But I cannot log in to the database using that new user name. I keep getting the message:
Code:
