I think I've messed my SELinux boolean values. How to restore default boolean values?

I don't know whether this is a kernel modification in this distro or my system is in compromise(I doubt for the latter option, but not confirmed).
View 4 Replies View RelatedI'm having trouble with my sound on my new Fedora 12 machine. when I first installed F12 sound was working but it appears that I have messed up some settings somewhere and now alsa is no longer recognizing my sound card (integrated into my ASUS M4A79XTD EVO motherboard)
Code:
$ aplay -l
aplay: device_list:223: no soundcards found...
I'm sure that when I tried to fix it I probably messed it up worse. Is there an easy way to restore all of my sound settings and audio Drivers back to the F12 defaults without losing everything else?

Or if user is prompted for hometown and he doesn't insert anything, but just pushes ENTER button, 'New-York' sis chosen by default Are such default values possible in bash?

My question is about TCP parameters in Linux. By now, I want to change the default values of:
Initial Timeout
ACK Delay
Idle Connection Timeout
I have a Linux Box with kernel 2.6.x and 2 ethernet interfaces. I know TCP is a stack that doesn't have anything to do with ethernet devices. Said that, the question: is there a way to set custom values for each interface? For example, a server listening to connections in eth0 would use one value for Idle Connection Timeout and another server listening to connections in eth1 could use a different value for that parameter.
So I am creating a LDAP server for my school's Linux lab, so users on our school network can log into the Linux machines.
I found a guide here url...Authentication
But during the install, I get the following error.
update-rc.d: warning: libnss-ldap start runlevel arguments (2 3 4 5) do not match LSB Default-Start values (none)
I ran two scans in Zenmap: 1) Quick scan plus and 2) Quick Traceroute. Quick scan plus, under the Nmap Output tab, has a field called "Network Distance". The Quick Traceroute report under the same tab lists the HOP and RTT time. I was thinking that for a given server, the value for the Network Distance would be the same as the HOP field when initiating the scans from the same server, but they are not.

View 14 Replies View RelatedWe are trying to implement a firewall as kernel module through netfilter hooking (in C). In the following code we are allowing only TCP traffic. Source port number and destination port number are printed for every TCP packet. On execution, this code prints wrong port numbers. This is the first time we are using skb_transport_header function for accessing tcp headers.
We verified port numbers being printed by firewall through NFS traffic. On the same machine where firewall is running, we hosted an NFS server. An NFS client (from a different system) puts a file in exported mount. Firewall is able to capture packets for this file transfer but port numbers printed are wrong. It prints '69' for source portnumber (whereas ethereal capture shows it as 790) and prints '553231' for destination port (whereas for nfs version 4 it has to be 2049).

Does anyone know why files in /boot are world-readable (particularly the initial ram disk)? I'm not an expert, but I would not expect anyone except root or a sudoer to have the ability to read these files.

View 2 Replies View Relatedi initially installed ubuntu, working with gnome for a while. i now migrated to kde as i like it better. however, the kde session still has lots of the "old" file associations set as they are in gnome...
some examples? text files open in gedit, instead of kate pdfs open in "document viewer" instead of okular double clicking zip folder opens the "archiver" (gnome?), extracting an archive from the archiver and then pressing the "open folder" dialog after extracting has finished, opens nautilus (although dophin is the default program for inodes). etc.
i'm aware of the possibility to edit file associations, however thats a tedious thingy to do, if you want to get it complete... furthermore, the file association edit dialog has the "defaults" button disabled, hence my questions:
is there any way to "restore" the kde default file associations, just as i would have installed kubuntu initially? i don't want to reinstall just because of this.
I was messing around with games on my desktop. I'm using lynx, relatively newly installed. I changed the mouse controls in one of the games to be more sensitive for movement. It seems like whenever I click on a windowframe in gnome, half the time the windowframe treats my click as a doubleclick. For days I've been messing around with the mouse settings under system>preferences, but I can't seem to get the settings right. Knowing linux, the mouse controls have to be set in a text file somewhere. How to reset my mouse preferences to the original defaults?
View 5 Replies View RelatedBecause Remastersys has a size limit for its backups, I exclude the Pictures folder. Therefore, when I do a restore, there is no pictures folder; when I create one, it gets the generic folder icon, rather than the folder icon that is normally associated with the Pictures folder. I know that through properties I can replace the folder icon with anything, but I have not been able to find where the generic pictures folder icon is stored. If I choose a specific icon, and change the icon theme, the custom icon remains. Further, when I make a bookmark for the new Pictures folder, it gets the generic folder icon, no matter what icon is assigned to the Pictures folder. There must be a way to restore the generic Pictures folder icon, so that it changes with the icon theme.
