Fedora Security :: Disable Strict Password Checking?
Jul 12, 2009
I'm not necessarily gonna do this, but I have to know. Is there a way to make the system not complain about every single freaking password you try to use? Make it so that any regular user could make "hello" their password without complaint? Like I said, I won't necessarily do it, but I have to know if it can be done.I did some searching and found the su -c "passwd username" trick, which is working for right now (I have root access but a user account I made for a friend doesn't)... it's just irritating when it won't even let him use something like "snuh123" because it seems to think it's based on a (reversed) dictionary word. Any use of a dictionary word, even with other chars, fails

What's the best way to handle checking for a similar password?
IE. What would a possible algorithm be to generate the error "this password is too similar to one of your previous passwords"
I thought about adding the ascii value of each letter and then adding them and looking for at least a difference of X.
What methods have yall seen used for this?

The problem is that yum is refusing to install gcc on a new SL6 install. As far as I can make out, a security update that I applied prior to my attempt to install gcc has caused problems. I did a new SL6 install (x86_86) a couple of weeks ago. This was a minimal installation, and I didn't install any dev tools, as I intended to install them later from yum. Since then, I've done very little; I installed a few packages (samba, xemacs, etc), and I let the system update itself. The update installed 'kernel', and updated 'kernel-firmware' [URL]. I now need to install the dev tools (g++, and so on), but I can't. I've tried this from gpk-application, and directly from yum. The complete yum output is below, but the basic error is:
> Error: Package: glibc-2.12-1.7.el6.i686 (sl)
> Requires: glibc-common = 2.12-1.7.el6
> Installed: glibc-common-2.12-1.7.el6_0.5.x86_64 (@sl-security)

We have a big proprietary project. Our code was compiling very properly with gcc 3.3.4 but not with 4.1.2.
The errors what we get is "ISO forbids declaration" / undefined symbols kind of.
my question is that is there any gcc/g++ compiler switch which can disable checking extra ISO confirmations and stick to our older ISO standards.
in addition to this how we can figure out what ISO standards are supported by which gcc/g++ versions

I have Fedora 14 with minimal installation (without graphical interface and so on) and the application I've been working needs to be initialized on boot up. So, I need to disable the login prompt (and password) by command line. How can I do it? I've seen by GUI, but with command line nothing...

I just installed umbutu 10 on a virtual machine running on VMware workstation 7.Workstation asked me for a username & password, which I supplied.The install went fine, and I logged on with the credintials that I provided to WorkStation. So far so good.I then downloaded Webmin and installed it, again no problems.I go to the provided link: URL... and it wants me to log-in as root.But I don't have the root password and checking umbutu it does not appear that I have a root user so that I can set a password.

I wanted to disable root logins in console, so I searched for that. I found that if I change root's bash to "/sbin/nologin" in "/etc/passwd", root user will not be able to login. So I did that. But when I wanted to use sudo command, it didn't show me root bash, but it only do the same thing as logging in as root in single user mode (shows message that this account is disabled). So, how I can disable root logins, but keep enabled sudo command for standard users?

I'm running Fedora 12, and I need to disable the firewall from within a shell script, which rules out system-config-firewall. I tried the following:
Code:
service iptables stop
service ip6tables stop
chkconfig iptables off
chkconfig ip6tables off
but that didn't do it.

I have an encrypted disk, using LUKS / dm-crypt, on Fedora 14.Every time I boot, I am immediately prompted for the passphrase. This happens VERY early in the boot process, and is a graphical screen (ie not console text). If I hit escape, I am prompted in a text-mode for the same passphrase. If I hit escape or return a few times, boot continues normally.
I only mount the disk occasionally, and don't want to be prompted at boot for the passphrase to luksOpen the disk at boot. I manually cryptsetup luksOpen and then mount it when I want access. I just don't want to be asked at boot, and don't want to unlock it until I do so manually.Does anyone how how I can tell Fedora to not attempt to decrypt / mount this filesystem at boot?It's not in /etc/fstab. I should mention, no LVM, just mdadm raid5 on the partition + luks /dm-crypt.

I post this to have a memo about how I looked into this problem. You can use this command to check what is hidden.
Code:
/usr/lib/chkrootkit/chkproc -v -p 3 | grep /proc/ | sed 's/.*(/proc/[0-9]*).*/1/'| xargs -n1 -I %%% cat %%%/cmdline
If it doesn't output anything, then nothing is hidden currently. This usually means that a process was started between the ps command and the /proc check of chkrootkit. You can check what those command(s) are by running the above in a loop, with high priority.
[Code]...
Does anyone know how to get rid of these false positives while retaining other functionality of chkrootkit?

Simply, the number of possible combinations of passwords increases as an exponent of the number of characters used and as a factor of the number of characters available for use.
26 potential characters for a 2 character password results in 26^2 possible password combinations. This means that each new character added would result in an "order of magnitude" increase in the difficulty of brute force attack.
Using a phrase, complete with punctuation and capitalization is the very best mnemonic device to remember a password. Consider this, how hard is it to remember; The quick brown fox jumped over the lazy dog.
Than it is to remember, l33tsp34kp@ssw0rd
If we pretend that both of these passphrases are generated from a character set consisting of 26 characters, the first would be one of a possible 15274273784216769021564085930704478424313742483024 510976. The second would be one of a possible 1133827315385150725554176.
In short, use a passphrase not a password, they are much MUCH more secure.

I'm interested in GNU/Tiger as recommended by a security guru I know. I did apt-cache search and located the package tiger:Code:tiger - Report system security vulnerabilitiesI also checked the ubuntu web-based package search and found tiger there too along with things like this signed message.Using apt-cache policy, I see this package is universe. I'd like to check the signature/cert/keys of this file before running apt-get install on it to see if it is acceptable given my current apt keys. Can someone explain how to do this?Also, what happens when I try to install a package using "apt-get install" and that package or one of its dependencies is:* unsigned* signed, but not by anyone whose key resides in my apt keyring?

I have been experiencing harassment with my websites being hacked so pardon me if this is an over-paranoid question.
Just recently started on FC11 after having abandoned Fedora for CentOS for a few months. So glad to be back, but...
I have been getting notices about security updates. When I click for the update, I am not asked for the root password and the update occurs.

I create music and usually gets sold world wide. I have some distributors that have been able to access a private server and get the new tunes I make to download via ftp. Well that server is getting full and I was trying to create another directory on my website itself.I created the directory. made the ".htaccess" file. Then I tried to make the htpasswd file but my server just keeps saying no command by that name.
