Ubuntu :: Mask/Alter Mac Address From Connections Coming Through Proxy
Nov 17, 2010I have a local proxy server running on my computer, but I want to add a twist to it. I have multiple connections going through the proxy, but what I'd like to is that all outgoing connections Mac Address' will be different from the one the connecting systems. Mask or even alter them, if possible.
Yes, I know the idea itself sounds weird, but I'm attempting a few ideas for a project I'm working and I ran in to this problem. Please note that it's impossible for me to change the MAC Address' on the systems connecting through the proxy (they're gaming consoles, to be specific.)
I'm currently running the latest version of Ubuntu.
Programming :: Shell Script And Administration Of A System - Change Or Set The IP Address And Subnet Mask
Aug 26, 2010tasks of an administrative level that we can use Shell Script to automate them. It's a kind of homework for me to figure out how to automate those tasks. Using PHP and Shell Script design and develop a Web Interface to change or set the IP Address and Subnet Mask of the UNIX / Linux System. The related services must be restarted automatically for the new IP Address and Subnet Mask to take effect. No user name and password should be asked for when using that Web Interface. How would you do it?

Jun 28, 2011I have a linux desktop with two connections - fast eth0 and slow modem ppp0. Most of traffic (e-mail, DNS, NTP) can be routed simply by IP/mask. But how about http and p2p (torrents, DC++)? Routing by IP is unacceptable, because there is very huge amount of routing rules. I need route http packets (80 port) through ppp0, p2p through eth0 (10000:65535 ports). I've found that splitting traffic by port is possible with marking packets for different gateways. For begin I cleared all tables and bringed up connections.
Code:
# iptables -F -t mangle
# iptables -F -t filter
# iptables -L -t filter

Ubuntu Networking :: Change Subnet Mask "ONLY", Without Touching Any Other Setting?
Apr 5, 2010I am using ubuntu Lucid and connected to a network with windows machines.Our network admin changed some settings in the network, and all machines need to change their subnet masks to access local machines (e.g. I am getting "unable to mount" message when I try to connect other Windows PC's on the network.)
If I open the connections panel, and "Edit" the "Auto eth0", I can get: IPv4 Settings -> Method -> Manual -> Addresses -> Add .And I am pretty sure I will put new subnet mask address into "Netmask" box, what to put others? Namely:
IP Address, Netmask, Gateway and below:
DNS Servers, Search Domains
I can get some info about my network connection by right clicking network icon on the panel, and select "Connection Information" Tried to fill manual settings with some of those info (the ones made some sense to me) but I still cannot mount windows network drives, plus my internet connection dies.So, is there any way to change Subnet Mask "ONLY", without touching any other setting.
Ubuntu Networking :: Port Forwarding From Public Address To Private Address?
Feb 24, 2010Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.
Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting
Dec 16, 2010Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:

I'm using to using ubuntu server where I just set the IP in the interfaces config file.

Networking :: Dynamic IP Address With PTR Record Versus Fixed IP Address Without?
May 7, 2010I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.

Ubuntu Security :: Create 760 But Even If Change The Mask It Still Generates The Same Permissions?
Jan 23, 2010I have a setup samba and want to get the correct security permissions when my wife creates / copies files from her camera onto the shared/mapped drive on her new laptop (windows 7) I want the permissions set to 770 or maybe 760. See my config below.
Now I can get it to create 760 but even if I change the mask it still generates the same permissions. After every change I restart the samba service. the umask is still 0022, do not know if that makes a difference? The directory permission's are correct with this mask. Do I need to look at groups?

Ubuntu Security :: Clean Mask For Files And Folders Through Samba
Feb 9, 2010Still working on the mask of files for shared folder. I now have a shared folder with the exact behavior I expect :
Code:
sudo addgroup share_group
sudo mkdir /media/volume/shared_dir
sudo chgrp share_group /media/volume/shared_dir
sudo chmod g+s /media/volume/shared_dir
sudo chmod 770 /media/volume/shared_dir
sudo setfacl -d -m group::rwx /media/volume/shared_dir
sudo setfacl -d -m other::--- /media/volume/shared_dir
emma@box:/media/volume/shared_dir$ ls -al
total 8
drwxrws---+ 2 root share_group 4096 2010-02-09 12:53 .
drwxr-xr-x 8 root root 4096 2010-02-09 11:58 ..
-rw-rw----+ 1 emma share_group 0 2010-02-09 12:53 test
By default, user from the group can modify this file. That's perfect.
I have define the share in Samba this way :
Code:
[share]
comment = Shared Folder
path = /media/volume/shared_dir
browseable = yes
guest ok = no
read only = no
hide dot file = yes
# force group = share_group
# create mask = 0660
# directory mask = 0770
# force create mask = 0660
# force directory mask = 0770
When drag & dropping a file in this share, here is the default mask:
Code:
emma@box:/media/volume/shared_dir$ ls -al
total 192
drwxrws---+ 2 root share_group 4096 2010-02-09 12:54 .
drwxr-xr-x 8 root root 4096 2010-02-09 11:58 ..
-rw-rwx---+ 1 emma share_group 6148 2010-02-09 12:54 .DS_Store
-rw-rwxr--+ 1 emma share_group 176684 2009-12-21 23:33 IMG_7487.jpg
So the dropped file have execution rights for the group, and read access for other. I expected it to have the same rights than the file created directly using the touch command. I tried to play with the mask options, without success. The file has been dropped from my mac, which is a Unix like OS. I guess that some authorization access are inherited from the original file, for the user and other parts. But where does the group authorization come from ? Moreover, is is possible to define in samba a default mask, whatever the authorization of the original file?

The password mask (*******) symbol font size is smaller than any other password prompt (for instance gksudo). Is it only me ?
Should I report it as a bug ?
It's a minor problem but may be it's caused from something more serious as I have other problems.
Also this dialog window (of the keyring prompt) doesn't "woble". By that I mean that the effects that I've set are not applied to this window?
General :: Mask Local Timer Interrupts In User Space?
Oct 27, 2010I am trying to figure out how to mask local timer interrupts on a specific core of a multicore system from within user space. The interrupts are causing latency spikes of 3-10u that we would like to remove. We are only running 1 thread on the core h everything shielded except for these timer interrupts. This thread makes no system calls and thus is never getting context switched out. I am not looking to turn them off entirely but rather turn them off, run my code, turn them on in a continuous loop. The thread runs in user space which we are hoping to maintain. We also have no desire to modify the kernel if possible. I've read about using spinlock_irqsave() but it appears (not positive) that it must be used within kernel space.
