Before upgrading to Lenny there was no noticeable delay between entering a username & the prompt for a password when logging in via ssh. Now there is about a 5-second delay which is rather annoying. There is no delay when logging in through the Gnome UI. Anyone know why the delay is there? Is it something about ssh under Lenny? Is there a setting that can be changed?
View 1 Repliesdelay the retry response from SSH (for, say, 10, 20 or 30 seconds) when a bad password is tried by a whacker? I mean, when I'm getting hit by 10 or more break-in attempts, is there some way to make SSH delay the next try from the site that's trying?I seem to remember something about this but haven't been able to find it and, so far, reading the SSH documentation hasn't been
I have DenyHosts running (that puts entries in /etc/hosts.deny after a few tries to break in) and I completely block China, Korea and a few others that are a constant annoyance with IPTABLES but I do get hit pretty much every day and would like to discourage the bastards as much as possible (the hits are a second or so apart which tells me they're automated and I figure delaying the response will discourage 'em).For example, here's the overnight entries from /var/log/messages (the "refused connect" are from /etc/hosts.deny entries generated by DenyHosts):

On a Debian 5.0.8 I have a problem with OpenSSH server (sshd): when connecting to it from another host there is always a 10 seconds delay before sshd gives login prompt to the client. After the connection is established the communication goes on without any interruption. This long delay started to happen a few months ago and sshd_config was not changed at that time.
Here is a short description of the conversation between the putty client (on MS Windows) and sshd:
- putty client starts connection to sshd
- 10 s delay
- sshd returns "login as:"
- user types username in putty window
- sshd returns "password:"
- user types password in putty window
- sshd returns MotD and shell prompt
Here is a short description of the conversation between the OpenSSH client (on a Debian 6) and sshd:
- client does "ssh user@host.foo.bar"
- 10 s delay
- sshd returns "Password:"
- user types password
- sshd returns MotD and shell prompt
I tried connecting from:
- local host - NO DELAY
- a host on the same subnet - delay exists
- a host on another subnet - delay exists
I've found the following suggestions but to no avail (of course I restarted sshd after changing its configuration):
- on server put "UseDNS no" at the end of /etc/ssh/sshd_config
- in /etc/hosts on the server define mappings between IP addresses and host names for the ssh clients
- on client use "GSSAPIAuthentication no" in /etc/ssh/ssh_config
Here are some logs and configurations:
I have made several attempts to install Testing. Down-loaded Apr 11 iso and verified the DVD. Everything went ok with install. It was when I booted up after removing install disk. I have Debian dual booted. Both Linux 10 and Debian Testing show up on the Grub screen. When I select Debian everything loads but when I get to the Debian screen I am asked for my password. However, the screen is lock up and no choice can be made. Three of my previous attempts (different install disks) have left me at the same place....locked password prompt. (4 year old HP Paviiion DV5000 laptop, 2 GB memory, 120 GB HD) I have successfully installed Debian 6 Squeeze with no issues.
View 7 Replies View RelatedI have just installed Lenny on a Thinkpad R50p. During the install I opted for no root password, using the sudo option instead (I've been used to this on Kubuntu for a long time). After installing, I added KDE 3.5 with apt-get install kde-desktop - all seems to be OK, except that I am unable to add packages or perform tasks for which a root / admin password is needed. It seems that the install-time choice of sudo (shared password) does not propagate to the KDE install, which is still expecting a root password.
how to either enable the KDE desktop to work with this shared password setup, or whether there is a better route to a KDE 3.5 desktop than just installing as I did (I am aware of Trinity KDE 3.5 but the Pearson Computing source is still not up, are those packages available for Lenny anywhere else, and are they recommended?). I can of course rerun the whole install and choose root & user passwords but if there is a smarter solution it would be less of a 'reinstall Windows' type of fix
I've had a very frustrating time the last few months trying to find a KDE4 based desktop that is stable enough and not lacking some basic functions (print manager, for goodness sake), so I have temporarily thrown in the towel and will try a Stable installation that is not changing (breaking) all the time, until KDE4 series gets past this adolescent stage of development and settles down.
I do need to get back to a system I can work on rather than keep on trying different installations!
I often need to login into various accounts. In Debian 7 I always was able to copy and paste passwords from text files if I was asked for an input, but now the textfield for password input locks the whole system and I can't do anything else before I have supplied the password. Is there any way of restoring the old behaviour to make password input forms (like the request for GPG key passwords in Evolution) just being an addintional app-window instead of an input request, that locks everything else? I want to be able to open the proper file with the login data when prompted for it.
I know I could theoretically solve this issue by using a general system wide main key which would supply all individual login data, but I want to memorize some often needed phrases by actually typing them when I need them. I just want the possibility to open text files for copy and paste when I'm prompted for a password if this is something I don't even want to remember.
I am new to using Ubuntu 10.10 that was installed by a friend of mine, but he didn't give me a password for administrator and now when I try to install VLC I am blocked by a password prompt. To make things worse I can't use F1 key, esc key, tab key, 1key (I copy and paste 1 from other pages when I need it). I am at a loss here and all I want is to change the administrator password without validating the current password first.

View 3 Replies View RelatedI have F10 installed on my laptop with disk encryption enabled. When I boot the machine I get a "Password:" request on screen but can't start typing for 30 seconds or more.Presumably the OS is not ready. This means I have to wait at the keyboard tapping a key until I see asterix. It's a waste of time and frankly a bit clunky for a modern OS. How can I change the behaviour so that the "Password:" request only appears when I can actually type?

While time passes, a process xfdesktop begin to use more and more memory and to free RAM i need to log out and log in again.
I tried squeeze yesterday on my virtual machine and it has 4.6 and seem not to have that bug, RAM usage is static(yes it still works when i write this and have memory usage 34492k, which is not changing for an hours of usage already), also 4.6 is MUCH better than 4.4.
i already tried adding squeeze to "sources.list" but i can see too many dependencies which should be upgraded if i install 4.6, i'm beginning to afraid it can crash entire GUI(or entire system, i can see there is libc6 required to be updated).
After GRUB 2 comes up (I'm running Ubuntu 10.10) and I choose the OS to boot, there is about a 5 second delay where nothing appears to happen after I make the selection -- no disk activity. It happens consistently every time I boot. Again, this is after I choose the OS to boot, so it shouldn't have anything to do with the standard delay to allow me to choose the appropriate OS.Is there a good way to troubleshoot this and determine what is causing the delay?
View 4 Replies View RelatedI'm writing a script which will log into a list of servers if they have public/private keypairs set up. If a server doesn't, I want the script to move on to the next server rather than wait at a password prompt.I'm using OpenSSH version 5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007 on both client and server.I'm using this command: Code: ssh root "at" "IP" -o PasswordAuthentication=no KbdInteractiveAuthentication=no I had to write "at" instead of the symbol, as I'm not allowed to "post URLs to other sites after you have made 15 posts or more."This works for most servers, but not all (on some of them the script halts at a password prompt). I suspect those servers may run an older version of SSH which doesn't support the options I'm providing

However, when it boots up it prompts me for my password so it can connect to my wireless network (I think it said something about not getting my user password at login). Is there anyway I can get it to remember this?
I would like to make this automatic because this will be a remote box that I will use as a file server, but it wont be turned on all the time. So I'll turn it on when I need it, but I'll need to connect to it remotely, so obviously it needs to be on the network.
Has anyone else encountered the really irritating issue of a hidden WPA network not auto connecting, and prompting for the root password when you manually select 'Connect to hidden wireless network'?
It works fine if I enable broadcasting of SSID but a proviso of my broadband is to keep this disabled. Ubuntu does it without any issue, can't figure out why it won't work on FC14.
So here's the problem. We've got the /etc/sudoers file set up so that users can run commands from /bin like "cat" or "mkdir" without entering a password. The problem is that the "su" command is also in /bin, so if they enter "sudo su", it gives them root access without a password. Here's the /etc/sudoers file:
Defaults targetpw
%users ALL=(ALL) ALL
root ALL=(ALL) ALL
support ALL=(ALL) NOPASSWD: /sbin/, /bin/, /opt/, /etc/init.d/, /elo/
support ALL=(ALL) NOPASSWD: /usr/bin/mysql
Is there a way I can deny /bin/su while still allowing the rest of the /bin commands?
I click on the corresponding checkbox in users and groups but but it doesn't do anything. I also want to disable password prompts in general. Also when I try using Computer Janitor it says it could not complete and to check if other package managers are open, but none are.

View 4 Replies View Relatedpresently my laptop requires a password when the screensaver has been activated(equivalent to the lock screen function). However, when I move the mouse to activate the password prompt, the screensaver freezes (all movement stops) and the password prompt is not visible. It's definitely there - if I type my password, then it brings me back to my desktop. However, if I mistype the password, or accidentally hit the mouse button so that somewhere other than the invisible password field is brought to focus, then entering the password becomes impossible, and I have to do a hard restart (ugh).

I was wondering if there is a way to mount a network CIFS share manually to allow it to prompt for password. I've been Googling around and found a couple options. One was to store your credentials in a file and then add the fstab entry to look at the file. I'm not particularly fond of the idea of storing my credentials in a plain text file though, even if I put file permissions on it.Is there a way to mount the share so that it prompts for credentials. The share isn't always online so I want to mount it manually.
