Fedora Security :: Resume From Hibernate - Terminals Still Logged In?
Mar 12, 2010
I am pretty new to Linux, but this can't be the way the system is supposed to operate.
Fedora 12
KDE 4.4
kernel 2.6.32.9-70.fc12.i686
Toshiba satellite L305D
As of updating KDE to 4.4 and a kernel update from two weekends ago hibernate/resume works perfectly. The problem is I feel that all terminals should be locked/logged out automatically upon suspend/hibernate. Through bug reporting at KDE found that an additional setting is required in KDE to lock the desktop before suspend/hibernate. But any of my other terminals that are logged in remain logged in upon resume. Is there an additional setting that I have to flip to secure the terminals? Would this be considered a security hole? Is there anything short of me manually logging out that I can do to automate locking/logging my terminals?

I want to count the number of users who have logged in multiple terminals ? How will I get this ? I always get the total number of users. How will I get the uniq number of users with multiple logins ?

My system cannot resume after hibernation. I have done all as described here [URL] ...
My have set up swap file "/swap_debian".
I have 3 partitions: sda1: windows boot partition. sda2: windows 8.1. sda3 : debian
I have the only linux distro installed: debian.
I have read lots of web pages. I have managed to set up suspend 2 disk. After dancing 2 days at the computer the system still cannot resume. I am getting "clearing orphaned inode" msgs while booting, and when booted to ram was not recovered.
Swap file is 4000 MB, RAM is 3860 something MB
My current grub is:
Code: Select all# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
[Code] ....
And yes, I did update-grub.
My current /etc/uswsusp.conf is:
Code: Select all# /etc/uswsusp.conf(5) -- Configuration file for s2disk/s2both
resume device = /dev/sda3
compress = y
early writeout = y
image size = 1855258869
RSA key file = /etc/uswsusp.key
shutdown method = platform
resume offset = 31606784
My current /etc/fstab is:
Code: Select all# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
[Code] ....

I found this line in dmseg when I was checking out another problem.
"[0.104467] ACPI Warning: Incorrect checksum in table [OEMB] - 03, should be FA 20090521 tbutils-246"
Could this be why I have never been able to resume from hibernate on this machine?

I have ubuntu 10.04 installed on a 50 gb partition on my hard drive I have given a 3.5 gb partition for swap which is > 3gb ram i have. Druing the installation of ubuntu I had specified the swap partition and its hibernate was working fine sometimes before. But I had to delete the swap partition and recreate it because of some reasons so I did that and again created a 3.5 gb partition for swap space usig ubuntu live cd.
But after restart ubuntu no longer detected the swap partition it was ok as its uuid had changed so I specified the swap partition to be mounted automatically by adding an entry in /etc/fstab and then also added the same UUID in /etc/initramfs-tools/conf.d/resume so that it could resume. After restarting ubuntu after adding the entrly in /etc/fstab i got the option of hibernate but after hibernate everything goes well but after hibernate when i start laptop again ubuntu first tries to resume but it does not and without giving any message it shows the login screen.

I'm experiencing very slow resume from hibernation. Last one was nearly 3 minutes. Sure, there is 2GB of RAM to read from disk (no SSD) to memory but that long?What could I check/do?

I'm using stock 32 bit current on a AAO D250 netbook. I'm running into a video issue after upgrade to the recent 2.6.35.7 kernel that doesn't exist after resume from suspend. The condition shows as a broken display that shows a black screen on the left with the KDE desktop partial exposed on the right side. Weird! My only fix so far is to blindly ctrl-alt-f6, login as root and reboot. The screen does not show the console screen during this reboot process
The pm-suspend logs show a clean hibernate and a clean thaw so that's no help. I've checked modprobe.d and don't have any alterations to any of the modules. The video module loaded is the intel_agp which sound right. I'm stumped at the moment.

I just got a Dell Inspiron 1764 and am dual booting it with Win7 and Ubuntu 9.10.Whenever I hibernate or suspend, it goes through everything fine, but then when I resume it just boots to a black screen and I have to do a hard shutdown. Is there a fix for this? I know it's a fairly common issue.

So I'm having this weird problem where my computer wants to continuously resume a session from hibernate no matter how I shut it down. I think it started when I tried to hibernate my computer with the battery really low. Somehow it messed it up. In any case, it can't resume properly, but gets stuck somewhere in the middle (I think when it's trying to sort out the resume image). Each time I power it on I have to boot it, restart in the middle of the boot so the boot menu comes up as it starts up again, edit commands before boot and add the "noresume" option so it will boot up normally.

I've got a Thinkpad X31 with ATI M6 Ly card. Since Karmic, and Lucid, I get no suspend/hibernate/resume. If/when I select resume or close the lid, Lucid goes through the suspend cycle, and for approximately half a second it actually seems to go into suspend, then the screen comes back on, black, but definitely on, and absolutely no response to any keyboard input - have to hard-shutdown by holding down the power button. I've read that the problem is with the Ubuntu kernel, and that installing/compiling 2.6.33 fixes the issue, but causes other ones.

The good news: 11.4 seems to have much better support for my radeon graphics driver which makes many of my workarounds for 11.3 unnecessary
The bad news: whereas previously for 11.2, 11.3 using traditional ifup meant that I could easily restore internet (either wlan0 or eth0) with ifdown/ifup now this seems to have no effect. I haven't investigated further yet since without internet on hibernate or suspend 11.4 is not my grub of choice at the moment
There seem to be quite a few glitches with the 'stable' release of 11.4 but this seems to be the main problem for me. (Minimizing the beta 4 Firefox windows closing them is another...)

After I resume from hibernate with my cpu frequency manually set to the highest settings (2ghz) the network manager shows not wifi APs. "wlan0" shows under both ifconfig and iwconfig but "iwlist wlan0 scan" says no results. "sudo iwlist wlan0 scan" also says no results. I've tried rmmod then modprobe with no luck. Rebooting is the only way I can get WiFi working.
I can get wifi working again by:
- rebooting
- changing the cpu scaling to a lower setting then hibernate/resume
- changing the cpu scaling to a lower setting then 'sudo rmmod ath9k; sudo modprobe ath9k;'
I am using Ubuntu 10.04 with Atheros ar5008 (AR5BXB72) using ath9k drives
Code:
$ lspci |grep Atheros
0e:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)
Code:
$ uname -r
2.6.32-24-generic

i dont know why my system dosnt resume from suspend sstate.i it goes in suspend state.it doesnt resume .i have to poweroff then restart it again.and when i get logged in it gives me Following Error: Resume problem: Your system did not appear to resume correctly from Suspend/Hibernate. This may be a driver problem or a hardware problem. Check the GNOME Power Manager Manual for common problems.
do you think it is because of batterry.i have a problem in my By Battery .IN DOS operating system.when i check my battery icon . A red Cross constantly blink on lower right side of the battery and it says (your Battery consider Replacing).i have notice one thing .And My battery timing hias become Decreased. Do you think this Resume problm is cause of battery problm.Or there is some problm in my Os software.

I am using Fedora 10 .Generally to update I open a virtual console by pressing Ctrl-Alt-F2,login as root and give the "yum update" command.Then I continue using my graphical terminal for other tasks from the 'non-root' account..Now my room-mate comes uses my 'non-root' account to browse web for few minutes and then opens a terminal types "halt", ENTER and viola...! My root account seems to be insulted by a 'non-root' user!.When I am doing updates or other important work as root any silly user can just 'halt' my computer. Can somebody tell me how to set up my computer so that when root is logged in no other user can simply halt the computer.

When I'm logged into my account, I can't shut down the computer if someone else is also logged in unless I supply the root password. However, if I log out, I can shut down from GDM without being challenged, even though another person is logged in, which could cause problems if that person is in the middle of some work. Is there a way to password-protect the gdm shutdown function if people are logged in?

I am running Squeeze on an older Compaq EVO laptop with radeon graphics.
A few months ago, after an upgrade, suspend and hibernate stopped working. The suspend or hibernate worked fine, but the resume just hung with a black screen. I finally got around to looking into it and found a workaround.
The workaround is to disable Kernel Mode Setting for the radeon. This can be done by adding the boot parameter "radeon.modeset=0" or by editing /etc/modprobe.d/radeon-kms.conf so that it includes the line "options radeon modeset=0".
If you are interested in the details, you can search for problem reports related to radeon kernel mode setting.

I have 2 servers, web server & mail server. they show 2 users in the summary area when I run w or top commands. But the actual list of users logged in (using either w or who) shows only 1 user.
ps -ef |grep username only shows my current login as a running sshd process.
So I can find no trace of this other user except in the summary line for w or top. I have no shells or other logins left running elsewhere or abruptly terminated, no gui sessions (these are servers), no tty logins. Do I have another user logged in? Has someone hacked me & covered up most of their trail? Why do these commands show 2 users when everything else points to 1 user?

I read the log
Code:
I found this print out:
Code:
The line in bold is the security issue. There is only 1 user account on the system. There should only be 1 user logged in, not 2 users logged in. The remainder of the log file lists 1 user logged in, for similar log output. 2 users logged in does not appear again in the log file.
Does the second line of bold indicate that an attempt was made to log in to the system using SSH?
There was an internet connection interruption (no service) around the time of the log file event. The service did return, later.
Does that line indicate that an unauthorized user logged in to the system?

Just noticed this, when I am logged into OpenSuse 11.3 under my default user (autologin) I have 3 of the same user logged in, eg when I run top it shows 3 users and when I run the users command it shows the same user 3 times. Is there any reason for this? Do I need to investigate this at all?

i have setup auto ssh login for my server. And it works, but only when i have a active connection. if i use "ssh server.com" it asks for my password. If i then open a new terminal and issue "ssh server.com" it logs right in. I really don*t understand whats wrong.
I have tried setting up 2 virtual machines on my local computer and with the same setup it works fine.
SOLVED: my home folder was encrypted, so when no users were logged in the home folder was unmounted

We have 4 servers having rhel 5.2. We have several users logged in on one of them. We have nis server/client running on them and have common home area mounted on all of them. Now we want to disable/block the accounts of the users who have not accessed our servers in last 2 months from today.What logic should we apply to do so? We were checking stat of .bashrc of each user but is not correct logic. We are going to write shell script for the same. We dont want to do anything in users home area or their files.

I installed IPlist earlier today on my main/admin account (which I only use for installing programs. I don't use this account daily.) and everything was fine. When I logged into my every day account and tried to load the program, it prompted me for my password. When I entered it, I got this message:Quote:Failed to run /usr/sbin/ipblock start_gui as user root.The underlying authorization mechanism (sudo)t allow you to run this program. Contact the system administrator.Does this mean I am not able to use this program on this account, or is there a way around it? I'm new to Ubuntu so forgive me if I'm asking the obvious. I looked around and couldn't find an answer. I really don't want to use my admin account for daily activities, but I also really want to be able to use IPlist

Failed login attempts are logged to syslog with the user id or login id set to UNKNOWN_USER or UNSET.Anybody know if this is configurable. I would rather it just pass the actual id that the user used. Doesn't matter if it exist or not, just want to know if someone is guessing at user names and what those user names are
