I would like to use my laptop at home, where I don't have internet access (don't ask, long story). My question are two-fold;
** How do I prevent various pieces of software trying to access the net for updates etc. I presume they are likely to hang, lock up, and generally cause trouble.
** Can anyone recommend a working practice for installing updates and/or new software, either from USB or CDROM/DVD? I have good (legitimate!) access to assorted computer facilities at my office. I am using 11.04
I'm doing a research to protect my pc from physical access. What I'm facing here is that my company created a program for fedora 8 and plans to sell the unit away. We created a function where you can configure the program using any web browser from a network so we do not want anybody to have access to the fedora except for out personnel.
Based on my research, I've found [URL] this guide to protect people from accessing grub and single user. I am currently researching on preventing others to clone the harddisk. I would like to know if there are any other methods to prevent people from unauthorized access to fedora.
Launching OpenOffice takes several minutes because it's trying to connect to the Internet. The problem gets worse in a dial-up connection. Turning off the Internet takes less than a second to start. How can I prevent OpenOffice from trying to access the Internet when it starts?
View 2 Replies View RelatedI am running a sever for a local community. There is arpwatch service running and monitoring for new network cards. The problem is that each day I keep getting lots of 'flip flop' reports:
Code:
hostname: <unknown>

I know where they come from: clients are obtaining ip addresses by DHCP, and initially are sending DHCP requests from 0.0.0.0. I am running arpwatch with a specific option to NOT report such things, but it looks like it is ignored...
Code:
arpwatch -u arpwatch -e admin -N -s 'root (Arpwatch)' -i br0 -n 0.0.0.0/32

How do I prevent eth1 from being able to overwrite the default gateway that eth0 has already set?!? I read that one can create route-* files in the /etc/sysconfig/network-scripts/ directory to setup static default routes.But those seems to require one to know the IP address of the gateway, but in my case the ISP's gateway is served via DHCP and so it could vary from day to day. Here are the contents of some of the relevant files:

View 11 Replies View RelatedI have a users, that log in from a terminal. They should not have any shell access, so currently their login script, at the end, starts the program that they use, and after that program ends, the login script moves on to log them back out. The problem is, they could press ctrl+c, while the login script is running, and it quits the login script and spits them out at a shell prompt. -- Is there any way I can prevent this?

View 2 Replies View RelatedI'm using some software that using mount point such as truecrypt. I also mount shared folder on other machine (fileserver) and publish it using ftp. The problem is when the truecrypt volume dismounted or the shared folder mount point loosing connection to the fileserver, user can write to the mount point without knowing that they actually not writing to the truecrypt volume or to the shared folder.
My question is, when sometime the server reboot and truecrypt volume is not mounted yet, how to prevent write to the mount point? I dont run truecrypt mount automatically for security reason.Some question for shared folder, if fileserver restart and the shared folder mount point got disconnected, how to prevent write to the mount point?
I'm working on creating a bootable Linux CD to distribute a sandbox environment to customers that will work on multiple PCs.One requirement of this environment is that we do not want the user to have any access to the underlying hard drives in the computer to prevent any accidental and/or malicious damage. I can prevent the disks from automounting with a few udev custom rules, but is there any way to prevent/block the user from manually mounting the hard drives after boot up.

View 6 Replies View RelatedI've lasted a lot longer than usual before resorting to asking around, but I've finally gone delightfully mad. I've been trying to access shares based on Windows 7 Ultimate with limited user access on said shares. I've managed to get into my XP machine, another mate's Vista machine and various Linux boxes with no issues, but that's only for shares that are accessible by everyone. The moment I try to get into a share that requires user credentials, I get "Error returning browse list: NT_STATUS_ACCESS_DENIED".If I try to access restricted shares (be it machine or folder) through Nautilus, I will get a user logon prompt, but it fails. Using smbclient results in just as little success, and now I'm munching through O'Reiley's Samba manual from '99, after realising that I need to basically learn Samba in its entirety to have a hope in hell at getting this to work. The trouble is though, every HOWTO and relevant forum post I get my hands on all seem to concentrate more on the server side of things, and usually servering from a linux box, not the other way around as I'm trying to.
The above Windows 7 machine won't even allow me to view its share contents, whereas the XP machine previously will allow me to browse, but won't allow me to access folders with restricted access. I'm pretty sure there aren't any major issues with the way the Windows 7 machine is setup, as it can be accessed with logon from my Xbox, Ubuntu machine, XP and Vista, with only Fedora having problems getting in as it constantly fails logon. What I'm trying to establish is, if Ubuntu can get in, is there something in my Fedora samba config I'm missing that's preventing me access? My thanks in advance to those of you who've been able to put up with me rambling.
How does one access a Virtual Box installed Fedora system? I'd like to be able to ssh into this system (locally) but I've no idea how to do this. There is an ip address of 10.0.2.15. Ping doesn't work (ping 10.0.2.15). Should I just go ahead and assign a 192. address to this box before I go any further? It would seem that at this point the system isn't actually a part of my local network and I don't imagine it would be unless it has a 192 address.

I am using ubuntu cli 10.04 for several different computers with different network cards, any time I plug in my persistent usb (ubuntu installed on usb) to computer the network would not work, when I find out what is up I see that it is up on next eth driver, I cant enter up to 50 or 100 or 500 entry there all the time and same thing with wireless since I use radius authentication its even makes it worse.
So to summarize:
sudo vi /etc/network interfaces
auto eth0 ifup dhcp
iface eth0 inet ...
...

auto eth100 ifup dhcp
iface eht100 inet ....
How to keep one entry for all those different computers (one for eth0 and one for wlan0)?
One of my ubuntu 10.04 boxes starts apache2 server automatically at boot. I know from the output of the command:
Code:
sudo /etc/init.d/apache2 status
I can't remember even setting that up, and I don't think it does so by default, since my other box in fact does not even have apache2 server installed. I can stop the server once I login, but is there a way to stop it from automatically starting the server, or even better, completely uninstall the daemon. I tried
Code:
sudo apt-get remove apache2
but that does not work. I guess the daemon is part of some bigger package.
I have two motherboards, MSI-6702 (64 bit single channel) and MSI-7511 (64 bit dual channel), I have two identical D-Link wireless cards and am running Kubuntu 10.10 on both systems. 7511 recognizes both wireless cards and connects to the Internet.The 6702 shows wireless grayed out on the connections page. The built-in Ethernet card has given out on both. I think I disabled it on the first system to have an Ethernet problem and wonder if I need to do it on the second. I would have tried it already but can' t remember how.
