I recently became co-owner of a server, however upon trying to ssh it became apparent the root admin gave me the wrong password by mistake;
After trying several times with the wrong pasword thinking I might have mistyped I have now blacklisted myself, huzzah.
How can I reset or clear the blacklist?
The package manager is scrambled in my Ubuntu 11.04. It started with the repositories list being scrambled with multiple entries. Now when the Package Manager is launched it just accesses the hard drive forever. I did give it a half an hour just in case so it clearly stuck in a loop of some kind.
What I'd like to know is: Is there some way to reset, clear, turn off or de-select the added Repositories list from the command line (terminal.) This seems to be the only way since the Package Manager gets stuck. Keep in mind that I'm only slightly competent with Linux and have no idea where the Debian Package Manager data is located or how it works. If I go poking around without at least some guidance I may make things worse.
The problem seems to be spreading. Got stuck again while saving this message. Turned off the system, rebooted to recovery mode and did a file system check. Okay for now. Switching to clean OS on other partition.
I'll check for answers there but it's only Ubuntu 10.04 and I'd very much prefer to have 11.04 working and not have an effectively dead partition and don't want to loose everything on it with a re-format and 2 day re-install process (no installation disk.)

I've installed the proper driver (I think), using ndiswrapper, and have blacklisted the conflicting driver (called ssb) to the 50-blacklist.conf file in /etc/modprobe.d/. My problem is that the ssb driver is still appearing as an alternate driver when I use the command ndiswrapper -l in the terminal. Where do I go from here? Am I correct that the ssb driver is not blacklisted correctly?

I've checked that I unload all of the ones depending on eachother so that shouldn't be the problem, I think. Does anyone know what I'm supposed to do to really prevent them from loading?

I am having a Oracle server installed on Linux server. I want to clear the buffers after a certain time interval. I use the following command for the same.
echo 3 > /proc/sys/vm/drop_caches
Can I have a script which will execute the above script after certain time interval OR a script which will execute the above command when certain memory size is reached.
I'm running OS X and it appears that after SSHing to several machines, using identity files, my ssh-agent builds up a lot of identity / keys and then offers too many sometimes to a remote machines, causing them to kick me off before connecting.
Received disconnect from 10.12.10.16: 2: Too many authentication failures for cwd
It's pretty obvious what's happening, and this page talks about it in more detail:
SSH servers only allow you to attempt to authenticate a certain number of times. Each failed password attempt, each failed pubkey/identity that is offered, etc, take up one of these attempts. If you have a lot of SSH keys in your agent, you may find that an SSH server may kick you out before allowing you to attempt password authentication at all. If this is the case, there are a few different workarounds.
Rebooting clears the agent and then everything works OK again. I can also add this line to my .ssh/config file to force it to use password authentication:
PreferredAuthentications keyboard-interactive,password
Anyhow, I saw the note on the page I referenced talking about deleting keys from the agent, but I'm not sure if that applies on a mac since they appear to be cleared after reboot anyhow. So, my question is, is there a simple way to clear out all keys in the ssh-agent (the same thing that happens at reboot)?
I have the following bash script:
#do some time consuming task here read -p "Give me some input: " input
Now as you might've guessed, if users press some random keys during the "time consuming task," they're read into input as well. how do I clear stdin (or at least ignore it) before I issue the read command?
I don't mind a few lines of reboots, but this is getting rather long:
How can I clear (or reduce) the history that comes up when ssh to my host?

What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong?
EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man

clear / ^L does not work.
I am unable to use clear or cls command on bash shell. I have recently installed Cygwin and am using that for practicing unix commands.
I see that I can use Ctrl + L to clear the screen. I created an alias in my .bashrc to do the same as
alias cls='^L'
This is how i defined other aliases e.g.
And they work. Hence I assume cls will work too but this is what I get when I try to give cls on command prompt. Am i missing something? Is there a way to do this?
Then someone suggested, You cannot alias keystrokes to commands or vice versa. You could just alias cls to an echo command: echo -en "x0c"
And I added the following to .bashrc,
Sourced the .bashrc file. No errors but cls still does not clear the screen. Infact when I typed the echo -en "x0c on command prompt as well, nothing happened. What does this command do?
I have a headless server running Centos and I often login in remotely to administer it. I have passwordless login and sometimes run commands remotely via ssh from a client machine. I've tried to shut the server remotely but have come across a small problem. Here is the output of the command I use to shutdown :Code:unclec@linux-desktop $ ssh centos 'sudo /sbin/shutdown -h now 'PASSWORD : 123ABCAs passwordless login is set up I do not need to enter a password to ssh BUT as I am running sudo on the server I am asked to enter my centos unclec password and this is shown in clear text on my local machine terminal. Is there a way to prevent this or should I edit the sudoers file on centos so it does not ask me to enter the password when "sudoing" ?

View 2 Replies View RelatedClosest analogy I can compare what I want to, is like the `sync` command, which writes out all stuff in the disk buffers, freeing the buffers.Instead of disk buffers, I want to 'clean out' my RAM and SWAP of any/all junk that's accumulated in there over the time my PC has been up. I've long wondered about this, but never asked, though I recall searching around several times..When I first boot it cold and log in, the memory usage bar on my desktop is near zero, and the swap is empty. But after a week or 2 or 3 or more of uptime, and with Firefox always running with a dozen tabs or so at any given time, I end up with all the memory full or 'filled with cached stuff', and the swap space is filled to capacity.Curiousity: I blame Firefox for leaking memory, but even if that's still the case today (historically it was) can this all be blamed on Firefox? Or what-all causes this, besides Firefox- just..Everything?
Here's current stats:
Code:
sasha@reactor: uptime
21:21:42 up 30 days, 10:07, 3 users, load average: 0.02, 0.05, 0.01
sasha@reactor: free
total used free shared buffers cached
[code]...
So, 3.8 of 4 Gib of RAM is occupied, and the 1 Gib swap space is jammed full 100%. This must slow things down to some degree, yes? I mean, the kernel does have to keep track of this, right?Of course closing all the applications doesn't make a difference (not an appreciable one anyhow) and the only way I have found to start fresh is to reboot.
What they don't make clear on most manpages is that you can't simply usebzip2 thisfile.xxx that gives bzip2 free rein to include the original extension in the filename. You must use the -c tag (and better than that, the -c and -k tags, the latter of which leaves the original file untouched post-compression), then -if you wish- the level of compression to apply to a file (in the range of 1-9, with 1 being next-to-no compression and 9 the highest level of compression), followed by the filename/s to compress, then after a single space, a right-hand carat (">"), then another single space and the name you want to give the compressed bzip2 file, remembering to add the extension ".bzip2" (no quotes) to your filename.
Sounds pretty obvious, doesn't it? Well, I thought so too once I read a particular manual page and reasoned it out. Then I remembered the 15 or so minutes it took me to Google myself to that manpage, and I decided it was good Net citizenship to put up a little step-by-step like this one on an appropriate forum on which I was already a registered member.

My landlord upstairs just got a new modem and WiFi by Clear.com and when trying to get the WiFi to work...it just wouldn't connect with my laptop. They have 2 computers upstairs, one laptop and one desktop that recognized the WiFi and don't have any trouble using it. Wondering if there is something I have accidently clicked or changed to make it not connect. It does not have an error message, it just does not connect completely.
