General :: Unable To Login To Server Through Console But Able To Login Via Network Using Putty?
Mar 13, 2009
I am not able to login to server from console attached to server, every time i enter username & password but it again asks for username & password. But when i try to login to server from remote machine, login happens properly.
I would like to learn basic linux commands and editors (eg : vi). Am using windows and it is difficult for me to install linux in ma laptop. So is there any free linux login servers available in internet so that I can login to server with putty and try using basic linux commands and editors.
I am using rhel 5.3. I am using windows 2003 server 32-bit (the processor is 64 bit. AMD athlon x2). I have installed vmware and installed rhel5.3 64 bit on top of it. Now i am able to login as root from GUI mode (f7 console), but unable to login in text console from f1 to f6. I checked the /etc/securetty. But there was nothing unusual there. I think udev is causing this problem, since google said so. I cant find where the udev.rules file is located that google searches are taking about. How do i enable root login in f1-6 console.
I got two computers with the exact same symptoms today: Both seem to be alive. They answer pings and they host virtual machines which are working. However, I cannot login via SSH. I get
$ ssh -v obelix OpenSSH_5.3p1 Debian-3ubuntu6, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /home/mike/.ssh/config debug1: Applying options for obelix
On the console I can switch the ttys and enter my login credentials. After that I see the GNU/Debian Linux welcome message an no prompt. The system seems to hang. I'm able to switch the tty again and login with the same result. (I tried that three times now and I start running out of ttys.) A search on the Internet suggested some ressoucre shortage. How could I release some resoucres than? How could I further investigate the situation before just trying a hard power off?
I setup logging in through putty client with keys, and password disabled, could log in from all machines on my network (xp and 7) with putty.When I finished hut down the server.Today I turned on the server box and thought I'd try logging in through putty. It kept telling me the server was rejecting my key.I plugged in a monitor and keyboard into the server and logged in via password then had no problem logging in through putty client.Question is, every time I shut the server down do I have to plug in the monitor and keyboard, then login, to be able to login remotely?
I don't what happened but yesterday I was working normally and then I shutdown the computer, today when I opened ubuntu it took me to tyy1 login screen, I entered my username and password then it took me to the normal login screen with the login drums sound and it wrote on my account (logged in) so I clicked it and I entered my password again and then I got to my ubuntu so what went wrong and how to fix it also I noticed that a new terminal in system tools occurred called Kernel (I didn't add it)
I'm using ubuntu 10.10 on Dell inspiron 1520 with Nvidia 8600GT and 3GB RAM
Important: this happened after update to generic-headers-24
I had successfully installed centOS,i am able to login as root.I created local users.But unable to login via console and FTP.As per the logs there were some LDAP issue,so i disabled LDAP and disabled PAM config as well.Now i am able to login to the FTP with the local users created.unable to login to the centOS console with the local user.
I just installed 10.04, and its taking me to the console login, rather than the graphical login. When I tried the live cd, the graphical environment was good. But after installation, I dont get the graphical login , so that I can get into the desktop.
I have a ATI Mobility Radeon X1400 card on ThinkPad T60. Everything was working on 8.10, and I decided to install 10.04 and now it doesnt work.
I just did "do-release-upgrade" from ubuntu 9.10 > 10.04 > 10.10 > 11.04 which successful but after a restart, no login console just a blinking underscore. However I still able to login to server using ssh. During the boot I saw this failure "Starting system V runlevel compatibility [fail]".
I know there are ways to change the login of a linux box (runlevel 3) so that you don't see the regular login prompt but that you get a list with options. You see this with appliances.
My goal is to create a login like some of those appliances have. Instead of just getting a login prompt you can select several options like login, change network configuration, change password, stuff like that. How can I do this? Is there an Open Source tool to configure this?
I installed dtc, dtc-postfix-courier and a few other depend software. When I re-started the server, I was unable to login with my usual login information. I am able to go to recovery mode to change the password but I am still unable to login to the system. Essentially, only root is able to access data on the server.
I'm brand new to ubuntu and very green when it comes to Linux in general.I have recently installed Ubuntu Desktop version 10.10 for my media pc (a friend of mine showed me xbmc, awesome!). I modified my install so that I don't have to enter a password when turning it on.The problem seems to be that when I did the install I chose to encrypt my home directory. Now, since I don't enter a password, the machine spews a few errors and does nothing. I finally got it to boot to a console window however I don't know how to undo what I did from the gui.I'm basically trying to get to System > Admin > Login Window > Security without the gui and "check the box" to require a password on login.Any clue as to which config file this setting is stored in?
i'm looking for a way to output a bash script to the console before login.It should be executed after boot in rc.d scripts with the output on the console0. It is for a asterisk box.This is the script. It use the watch command to output the active calls on the box in realtime.Code:watch "asterisk -vvvvvrx 'show channels verbose'"Btw,
I recently powered up my netbook... Selected my user log in, entered my password, and after a couple seconds I briefly see what looks to be the console and am returned to the login splash screen... I can Ctrl+Alt+F2 to get to the console and log in... but that is as far as I can get. This is the case for Gnome, Remix, and Remix 2D.
I can sudo apt-get (update, upgrade, etc) as well. It is the right password because if I type in a wrong one it presents an authentication failure dialog box.
How can I fix my log in screen and get to my desktop? I am Currently running 10.04.... waiting to get 10.10
System was fine with :Ubuntu 9.04 (had also installed kde )then....I wanted to try some change to gdm so i downloaded gdm while building it , it asked "PAM" libraries to be installed so i installed PAM ... but ignored the instruction to reinstall SHADOW (library i guess..),Now :on booting system i get login menu but i am not able to login , it says some critical error occured
1) install new copy of UBUNTU and remove old
ps :1) i can log into system through live cd
2) i can use recovery mode boot and log into terminal as root(startx is not working from this terminal..
I have an iMac G4 that I installed Jessie on successfully. However, when it boots, one of the last messages is:
[FAILED] Failed to start Load Kernel Modules.
Last line is something along the lines of:
fb: switching to nouveaufb from OFfb NVDA,NVMac
And then the text starts dissolving, and the entire screen cycles through different colors. I presume it is sitting at the graphical login prompt but it's not displaying correctly.
Based on some Google searches, it seems like I should be able to resolve this by editing /etc/modules but I can't get to that point. I have tried to get to a terminal using ctrl-alt-F1 through ctrl-alt-F12. No luck. I tried different yaboot options that were supposed to avoid using the video driver. No luck. How do I get the machine to boot straight to a regular text login instead of the X one?
This machine worked fine running Mac OS X this morning, so I don't think it's the hardware. What I can do.
Is there anyway I can disable an account from being logged in via Putty, but permits someone else to "su" into the account? For example, an application is being run as "app_account". Because there will be multiple people administering this application and the password is shared for this "app_account", I want to disable 1st level login for it. I want to make it such that only the permitted people can "su - app_account", once they have logged into their personal account. How can I do this? If I set app_account's shell to /sbin/nologin, the users are also not allowed to do "su - app_account".
I have a need to start an application on bootup on the linux console and I do not have a need for any type of login or security. I do not need any ALT-F1,F2,etc virtual consoles but I would like to allow SSH access via the network port for debugging, loading, etc.
The application is a SDL graphics program running with fbcon as the SDL_VIDEODRIVER if that matters. I'm currently using Fedora 10 and 12 but any distro that supports SDL using the fbcon framebuffer would be acceptable.
I unable to connect to samba but after change the register (Windows7 - SambaWiki),I could login and map/access the share drive.but when I try to shudown/restart/logoff win7 , the screen just stop with windows logo without the shutdown/restart words coming out.
I'm new to networks and servers, been using Linux on the desktop for a while now but always relied on the company's IT guy for setting up everyting LAN-based.
Now I want to build up my home LAN, and want to do it with Linux. I've managed to set up LAMP and file share servers.
What I am looking for is information on what I need, and how to set up a server for the following tasks:Centralized Username and Password, that when the user logs into any one of the desktops in the LAN, it uses this for authentication
Something that allows this authentication to be utilized in other servers (file access, web access, router logging, etc.). Something to make it easier for continuing permissions from one service to another. e.g. I have IPCop filtering content, and it has provisions for tracking who is making which request if there is authentication going on. (optionally) to run a script for mounting Samba shares or mapped network drives so from one system to the next. For example, in whatever box somebody logs in, it mounts a server share ("smb://Myserver/users/<username>") to a local folder ("my_user_share").
So;user "fred" ="smb://Myserver/users/fred" and user "wilma" = "smb://Myserver/users/wilma" but both would find their respective one mounted under "~/my_user_share". This would be irrespective of which box they are loggin in with. If the server share location changes (new server/servername), I change it on the server so the next time they log in it points to the right place.
I guess it is similar to Window's Active Directory, though I'm not sure what it's called, how to configure it and what it is and is not capable of doing.
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: Invalid user ldapu1 from 192.168.85.1 Dec 22 20:06:31 redhat5 sshd: input_userauth_request: invalid user ldapu1 Dec 22 20:06:37 redhat5 sshd: pam_unix(sshd:auth): check pass; user unknown Dec 22 20:06:37 redhat5 sshd: 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: pam_succeed_if(sshd:auth): error retrieving information about user ldapu1 Dec 22 20:06:39 redhat5 sshd: 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
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.
