Debian Configuration :: Login Failure After Installing Nvidia Drivers

Sep 17, 2015

I'm new to Debian and installed it with Cinnamon because I want to learn some OpenCL programming in Linux. I have a Nvidia GT 525M GPU. Once the operating system is installed, I followed [URL] ..... article to install the proprietary Nvidia drivers. As the forum suggested, instead of creating an Xorg server configuration file, I installed Bumblebee according to [URL]..... article.

But when I restarted my machine after completing all the steps when I try to log in I get the follwoing message:

"failed to load session 'cinnamon'"

I cannot login as normal user or root.

Debian Configuration :: Can't Login On The Ldap-client Via Ldap

Aug 9, 2010

why i can't login on the ldap-client via ldap, so here is a short description of my machines (i use openvz virtualising)I have on the HN (Debian Lenny) 2 VE's, which are in the same subnet (192.168.1.0/24)The first VE (Hostname: ldap1, IP: 192.168.1.91) is the ldap-server, which is so configured, that i can manage the server via phpldapadmin.The second VE (Hostname: ftp1, IP: 192.168.1.31) is the ldap-client, there should run a sftp-server in the future and the sftp-server(ssh-server) should use ldap-usernames to login. on the ftp1, i get with this command getent passwd the users configured on the ldap-server, but with the command id USERNAME the result is, that the user doesn't exist. (USERNAME is this name, i get returned by getent) and if i try to login via ssh, i get permission denied. and because the machines are openvz-virtual-machines, so i can't login on them like on a normal system, but a su USERNAME doesn't work too, because the user is not known on the system.

my installation:

i don't think, that the ldap-server is the problem, because the phpldapadmin and getent on ftp1 are working perfectly, but if you want, i can post the config here too. the VE ftp1 was configured with the following how-to: [URL] and pam is configured like in the chapter "PAM setup with pam_ldap" on [URL]

Debian Configuration :: Reboot Both The Server And The Client Machines Every Time Change The SAMBA Configuration?

Apr 5, 2010

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.

My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

Ubuntu Servers :: OpenLDAP Install 10.04 And Client?

Nov 15, 2010

There are several parts of problems in my question.

1. Install openLDAP and authenticate clients

2. Simple way to authenticate Ubuntu clients (just like Windows simple domain model, but Linux)

Part 1 What I have done: I have been working on openLDAP for the past 4 weeks. There is a lot of information on LDAP and I have read a lot of it There are several guides out there for openLDAP installation on Ubuntu, and I have tried many of them, and reinstalled the server between tests.

[Code]...

Part 2 Simple way to authenticate Ubuntu clients (just like Windows simple domain model, but Linux)

I have tried to find something similar to Windows client login, but haven't found anything that works. I just need to be pointed to somewhere to read about the authentication model in Linux. I can work out my from there. It must be something very simple I am missing, because when I read som echapters in The Ubunutu Bible, I can't find anything on it.

CentOS 5 :: Openldap Client Won't Bind To Server

Jul 2, 2011

I can't get the client server to authenticate to the openldap server. I can authenticate on the server itself though. I can su to, login and shh into the openldap server and become a ldap user. I just can't become an ldap user on the client.I didn't setup TLS/SSL. I can do that after I have it working. I'm using hashed passwords though. I don't have replication setup. I'm am tying to setup the most basic openldap environment then build from there. I have read the openldap section in the admin guide.

My setup at home.

Openldap server � light.deathnote.net -- 10.0.1.21
client server � vm-centos01.deathnote.net � 10.0.1.7 -- VM on virtualbox
Virtualbox host � L (OS MAC) � 10.0.1.2
router (apple airport extreme) / default gatway � 10.0.1.1

All computer can reach the internet and ping each other. When I installed centos I disabled SELinux.I used these guids to setup my openldap.

[URL]

Below I have included some output from the files I'm using with openldap.

[root@vm-centos01 ~]# tail /var/log/messages
Jul 2 09:25:33 vm-centos01 xfs: nss_ldap: reconnecting to LDAP server (sleeping 16 seconds)...

Debian Configuration :: Host Name Resolution Failure?

Aug 15, 2011

I am experimenting with installing a bare minimum, network capable installation of Debian Squeeze. Right now, I am having trouble getting proper host name resolution. I have provided the output of ping (which is able to resolve names), wget (which is unable to resolve names), and the contents of the files I believe to be relevant to the problem. When I installed Debian, I installed *only* the SSH Server from the list of available configurations. Since then, I have installed mdns4, dnsmasq, mdns-scan, and libnss-mdns to get name resolution to work with no success so far. All packages were installed with no recommends -- aptitude -R package name. What am I missing to get host name resolution working?

I have not seen this before and am not sure if it's related to the fact that this is a virtual machine and not a physical server or something else.

Debian Configuration :: Can't Get DNS Client To Use What's In Resolv.conf

Jun 18, 2010

My Debian workstation is on a predominantly Windows network. It is resolving internet addresses (i.e. www.google.com, etc) just fine. However it's not resolving any of the address of machines on the local network and the windows machines do not resolve the linux machines address either. All machines (linux and windows) can access each other just fine via direct IP reference.

My /etc/resolv.conf file has the following IP addresses listed:

127.0.0.1
10.1.1.111
10.1.3.4

10.1.1.111 is a netgear VPN/router that is the primary router for the LAN and maintains a VPN to a remote office 10.1.3.4 is the IP address of the Windows Primary Domain control on which the DNS server is running. That server is at the remote office. The system acts like it is completely ignoring anything I put in the resolv.conf file. From the linux X server I'm using "Network Setting" utility to make changes to the network configuration. This appears to work fine for things like switch between DHCP and static IP.

Debian Configuration :: Configuring NTP SRV In Local Client?

Jan 5, 2011

I'd like configuring NTP service on my Lenny Debian client to retrieve time from my local NTP server, so I thought to configure /etc/ntp.conf and to insert into crontab this command 'ntpd -qg', which is indicated in man. Can I run ntpd service to synchronize time for my client, avoiding to listen on port 123, beacuse my scope is to alignment time on client and to not give service to others, for this scope there is ntp server !

Server :: OpenLDAP Configuration On Red Hat 5.4?

Jul 13, 2011

I have a RHEL 5.4 server installed in a server farm. The server is administered under a central AD, which means that administrators are registered in the AD.

However, I have to deploy an application on the linux server, that will use it's own OpenLDAP server. This means that this application will be the client to the LDAP server installed on the same RHEL server.

I tried installing OpenLDAP using yum and it resulted in a very fatal issue. Somehow the configuration files used for finding the Linux server from the AD was overwritten and the Linux server was not reachable anymore.

After some investigations, and possibly, rebuild, the server has been handed over to me.

The problem is how should I install OpenLDAP so that the existing connection to AD is not lost.

On the Linux server I see a /etc/openldap directory but only contains ldap.conf and cacerts directory.

Server :: OpenLDAP Authentication - Unable To Login?

Dec 22, 2010

I have configured a ldap server and trying to login to same ldap server using a ldap user. However, I am not able to login and getting the following in /var/log/secure:

Dec 22 20:06:29 redhat5 sshd[7241]: Invalid user ldapu1 from 192.168.85.1
Dec 22 20:06:31 redhat5 sshd[7242]: input_userauth_request: invalid user ldapu1
Dec 22 20:06:37 redhat5 sshd[7241]: pam_unix(sshd:auth): check pass; user unknown
Dec 22 20:06:37 redhat5 sshd[7241]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.85.1
Dec 22 20:06:37 redhat5 sshd[7241]: pam_succeed_if(sshd:auth): error retrieving information about user ldapu1
Dec 22 20:06:39 redhat5 sshd[7241]: Failed password for invalid user ldapu1 from 192.168.85.1 port 4461 ssh2

I can see that if I use the ldapsearch with same filter, I am not able to locate the user "ldapu1". However, if I change the filter to (|(objectClass=posixAccount)(uid=ldapu1))", it shows me the ldap user:
[root@redhat5 ~]# ldapsearch -x -b "ou=Users,dc=homeldap,dc=com" -D "cn=Manager,dc=homeldap,dc=com" -W -H "ldap://127.0.0.1/" "(|(objectClass=posixAccount)(uid=ldapu1))"
Enter LDAP Password:
# extended LDIF
# LDAPv3
# base <ou=Users,dc=homeldap,dc=com> with scope subtree
# filter: (|(objectClass=posixAccount)(uid=ldapu1))
# requesting: ALL

# ldapu1, Users, homeldap.com
dn: cn=ldapu1,ou=Users,dc=homeldap,dc=com
objectClass: inetOrgPerson
cn: ldapu1
sn: ldapu1
uid: ldapu1
userPassword:: bGRhcHV1MQ==

# search result
search: 2
result: 0 Success
# numResponses: 2
# numEntries: 1

Where I have made a mistake?
- Is it necessary to create an account on Linux box and then migrate it to ldap?
- I was just wondering if I can somehow change the default filter from AND to OR at the time of login. I used "pam_filter |objectClass=inetOrgPerson" in ldap.conf.
However, it didn't change the filter.

Debian Multimedia :: SFTP Client Setup - User Based Login

Nov 22, 2010

I have setup SFTP and it is running without any problems. The problem I have is finding a client that supports key based logins through Linux. I do not want user based logins available and so far the solution works through my Windows machines using WinSCP. The only client I have found for Linux seems to be FileZilla but I have to convert my private key to the FileZilla format which removes the passphrase leaving it nice and insecure.

Security :: OpenLDAP / NSS / PAM Produce Logs Of Failed Login Attempts?

Feb 16, 2011

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)

Debian Configuration :: KDM "failure" On Boot - Squeeze

May 26, 2010

Hardware at issue is an nVidia GeForce 9600 GT. Issue occurs regardless whether the driver is downloaded and installed from nVidia, or installed via Synaptic courtesy of the new dkms package in the repositories.

It should also be noted that the issue only arose after an update today, as follows:

I do not believe it is related to the last three items in that list. Because everything worked perfectly before todays update, it would appear that one of those other updates is causing KDM and nVidia to not want to co-operate with each other.I also notice that, new to the boot sequence, the system is booting with "concurrency" - never seen that scroll by before - which may have something to do with it too.

OK, what happens. KDM "fails" to start when booting the computer. Symptoms : At the appropriate spot in the boot sequence, the screen goes black (as usual), but then, instead of the cycling cursor followed by the logon screen, the nVidia logo appears, and after about 7 or 8 seconds, the screen goes black for about a second, then drops me back at the console. From there, I can log in as root.

Now, the thing is, KDM is actually running, but using <control> <alt> <F7> only brings me to a blank black screen. By issuing the command /etc/init.d/kdm restart, I come up to a normal logon and can proceed as usual. As well, if I delete xorg.conf, system boots OK.

Looking at the system log, we find :

And then some way past that we get :

Should mention that was using the latest stable driver from nVidia (195.36.24), but in the hope that maybe something in the latest beta may solve the issue, installed that, but the answer is nope And yes, completely uninstalled the nVidia drivers between each test of the nVidia driver, the same driver in the repositories and the latest beta driver, before anyone mentions.

Debian Configuration :: Wlan0 Gets Deactivated While Login

May 13, 2010

From yesterday on, I am not able to connect my Laptop to my WiFi Router automatically when logging in to gnome desktop.

The following is the message found in /var/log/messages.

Its Lenny 5.0.4 and I can see my wifi LED ON till the gdm login page. After the login, while loading my desktop, the LED goes OFF and I have to restart the network-manager for enabling the wifi again. Why is this happening? Do I have to change the configuration settings in /etc/dbus-1/system.d/ to fix this. I really don't know what change needs to be done there and where.

The same day when this problem started while logging in I got an error message from nautilus. The screen-shot is attached with this mail. Does this error have anything to do with the network issue?
