Server :: Debian Root Password Stopped Working

Nov 5, 2010

sometime ago i have setup a nice Debian FTP server. and left the company. everything was working fine for about 5 month, administrator was able to login to root, do changes and manage system, etc. Suddenly he told me that he cannot login via PUTTY, the root user and pass say Access Denied.Looked all over the web for at least a REASON, but did not find anything. I suggested to go and do passwd reset, via runLevel 1. i hope this helps him. But i am still curious why all of the sudden, in a locked down room, where only one person has access root get disabled.

Debian Configuration :: Root Password In Console Not Working?

Sep 4, 2011

Reinstalled Debian Squeeze (64bit/gnome) on my Notebook using Netinstall. Everything worked like always but in the setup instead of typing in a root password as asked to i just pressed enter (in the hope of not having to type in a pw in the console later, just having to press enter then)

When i needed rootpw to install some software (using SoftwareDownloader) the normal loginpw seemed to work, but not in the console.
ari@HP625:~$ su -
Password:
su: Authentication failure

CentOS 5 Server :: SFTP Login For "root" Stopped Working?

Apr 9, 2011

I've been administrating a dedicated Linux CentOS 5 (Linux 2.6.26.5-rootserver-20080917a) server for around 2 years, and although not a network or Linux expert, been learning to configure as need arises. Primarily using Plesk for day-to-day, but occasionally using Putty to SSH into server.

For all the time I've had the server, I've been connecting to my server via sFTP using "root" password. ( Although, I know this is really bad practice, I assume made safer by connecting with SSH FTP)

After spending another normal day in the office developing websites, connecting to my server as root using SFTP in Filezilla AND Dreamweaver I left for the night.

Returned next morning, after having done no manual updates or amends to my server; I could no longer SFTP into my server?

Thought it may be related to my office network, so tried it from home over the weekend, same result; can no longer connect SFTP for root?

I can connect to the server via Putty using my "root" username and password.

After spending hours looking on the internet for a solution, I'm lost for ideas as I didn't make any changes?

What happens when I open my Filezilla and try connecting as SFTP is it states:

Error:Connection timed out
Error:Could not connect to server

I checked server log /var/log/secure and it states:

Accepted password for root from UNKNOWN port 49212 ssh2
Apr 9 07:41:41 s15320264 sshd[7122]: fatal: Write failed: Connection reset by peer

Odd part is, it's worked fine for weeks, months without ever failing to connect?

Also, notice that Putty connection seems to take much longer to authenticate root user than it used to?

Checked via Plesk Health Monitoring and all CPU, Memory and Disk Levels are well below any alarm levels.

I have run all Plesk updates to 10.2.0 in the hope that it resolved it, but to no avail.

Debian Configuration :: Ssh Randomly Stopped Working On Server?

Mar 15, 2010

I'm in somewhat of a sticky situation. ssh has just randomly stopped working on my server after a power failure. Everything else that doesn't rely on ssh is still working fine though. It can still receive mail and everything, just no ssh.Background on the server, running debian etch on a PPC machine.ssh is (supposed to be) running on port 2000. Even if I am physically logged into the machine I can't log in with ssh -p 2000 user@127.0.0.1.
I can ssh to and from any other machine on my network (the server can even ssh into another machine). So it isn't my network causing issues.It seems like the port 2000 is completely closed, if nmap the server's IP address I get PORT STATE SERVICE

25/tcp open smtp
80/tcp open http
110/tcp open pop3

Debian Configuration :: Plex Media Server Suddenly Stopped Working

Jan 27, 2016

My plex media server suddenly stopped working after years of no hassle use. This is the output of cat /proc/version = Linux version 3.2.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.65-1+deb7u2

My problem is similar to this forum thread viewtopic.php?f=5&t=121945 where I can get it to start by running Code: Select all/usr/sbin/start_pms & but it's not my normal server configuration. I added a couple files to it and it seems to work except it doesn't start when I reboot. I have to run that command again.This is the init script I've been running for years...

Code: Select all----
#!/bin/sh
### BEGIN INIT INFO
# Provides:          plexmediaserver
# Required-Start:    $remote_fs $syslog $networking
# Required-Stop:     

[code]....

My Debian skills are lacking to know how to proceed with troubleshooting what could have happened. Everything else seems fine, I just can't seem to get this application to run at startup or get back my old configuration...

Slackware :: VirtualBox Stopped Working For Non Root User After Updates

Oct 21, 2010

I haven't used my VB for a few weeks however all of a sudden it refuses to work for my normal non-root user. It's almost as if it can't find libraries in the /opt/VirtualBox directory. Initially it refused to start completely so I linked the required libs into /usr/lib64 ( yip real hack. Then it started but a vm would not start, and comes up with an error about a missing lib again which is definitely there. My non-root user is in the vb group and nothing besides system updates has changed. vb 3.2.10 slack64-current.

General :: Mail Server : Reset The Password For It Using The Password Command From The Root Login?

Jul 23, 2009

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?

Debian :: Root Login Without Setting Root Password

May 14, 2015

I edited fstab to automatically mount my windows data partition on boot, but I screwed it up by not specifying the file system type, however that is not the problem, I was able to fix that easily. The problem was that when it failed to mount the partition, Debian automatically entered root and I guess that is to be expected in order for me to fix it, but I never configured a root password and it just gave me full root access without asking any password, not even my user password. I though that was strange so I set the root password and sure thing it asked me for the root password this time without automatically logging into root....

I then tried to lock the root account to see if it will ask me for a password or not, it did but of course I wasn't able to login as root because it was locked now and I was left with no way to access the system. I had to fix fstab from a live cd so that I can login normally as the user....

I didn't know what to search for or if that is the expected behavior if you don't set root password during installation, but it just seemed a bit strange to automatically enter root when you specifically disable root login during installation...

Ubuntu Servers :: Root Password Not Working - File Structure Unreadable

Aug 31, 2010

I have one of those ultra reliable Ubuntu servers in the corner that I never have to logon to because it never needs anything. I needed to check up on it today and my root password would not work. I am absolutely sure I did not forget my password and because I am the only Linux guy in the office I am sure some nimrod didn't get his fingers in the machine. I attempted to enter GRUB recovery mode but when I hit ESC it says something about no disk and goes into the booting process. I attempted to use a desktop version live CD, but the file structure is unreadable, I assume due to the security of the server system. Before I rebooted it the server worked fine, Apache and PHP were working away. Now the whole thing is a 50Lb boat anchor. How can I reset the password when I cannot enter GRUB menu or use a live CD?

Server :: Passwordless Ssh Stopped Working?

Aug 18, 2011

There are a few threads about this but none seem to me.I have 3 machines setup with a nfs home directory on machine 1.I have created keys using ssh-keygen -t rsa (and left everything blank), then as user on machine 1 run

Code:
cat id_rsa.pub >> authorized_keys2
chmod 644 ~/.ssh/*

this used to work until I upgraded to ubuntu 11.04 (from 9.04), and now it requires a password to ssh. I have tried several times deleting ~/.ssh/* and recreating, to no luck Below is the results when I try to ssh into -2 from -1:

(dumb question, but shouldn't the offered RSA public key be id_rsa.pub rather than id_rsa?)

Debian :: Flash In Iceweasel Stopped Working

Apr 27, 2010

I just got a new pc after my two pc's decided to die. I have had them for many years, maybe around 2001. So, I am new to this 64 bit OS. I'm running squeeze amd64. I am having some troubles with flash in Iceweasel. It just stopped working one day. So, I downloaded Firefox to see if flash would work in it. Here's the interesting thing. Iceweasel will play flash. I will close the browser and reopen to discover it no longer wants to play flash. I'll open Firefox, then close it. I'll then open Iceweasel and Flash will work in Iceweasel again.

This happens often. To get Flash to work, I just close Iceweasel, open Firefox, close Firefox, open Iceweasel and go to a flash site and all is good. Is there something I can do to get Flash to always work without opening Firefox?

Debian :: CUPS Stopped Working With HP LaserJet 4 Plus

My printer is a HP laserjet 4 Plus. It used to work with the gutenprint drivers pretty much since always.I don't know when it broke, because I don't use it that often. I have tried with the generic postscript driver, with the gutenprint driver, with the j4dith driver and with the hplib driver. Basically, what happens is that all jobs never finish processing in the queue. On the other hand cups-pdf still works.

Debian :: Flash Audio Just Stopped Working?

Jan 1, 2011

So everything was working perfectly on my system. I have Debian SID, with the debian-multimedia repos and liquorix repos for kernels. Flash worked perfectly one boot, then the next boot the video still works perfectly but no audio. I found several "fixes" on the web, including creating .asoundrc in your home directory and another that said to
Quote:edit /etc/firefox/firefoxrc -- change the line FIREFOX_DSP="none" to FIREFOX_DSP="aoss"neither of those have done anything. Have tried using both the flashplugin-nonfree and flashplayer-mozilla, same thing on either. ALL other sound works, smplayer, amarok, system sounds, etc.
