Debian Configuration :: Kernel Using Multiple Featuresets?

Aug 15, 2010

I was wondering if/how it would be possible to compile a kernel package where two featuresets are applied. I notice that xen-vserver seems to have been done and wanted to make a xen-openvz kernel if possible to use VZ containers in a Xen DomU. I've tried reading the metadata files in the debian/ dir of the kernel source but there seems to be a lot "going on" and I couldn't make much sense of it...

I have a problem with my custom kernel when I want to create the Nvidia kernel module.After this finished I installed the image and headers and created the Nvidia kernel module. Everything worked fine.However, if I remove the linux-source from my home directory then I can't create the kernel module.Even though I have the headers for the kernel installed.

Debian Configuration :: Squeeze D-u - Kernel Configuration Skipped

Jul 6, 2010

I have a set of vm's with stable, testing, and sid to keep track of how things are going. When I did an apt-get dist-upgrade with squeeze last week, things seemed to OK (350 package updates) until the end. It didn't seem to like and / or was confused by a kernel dependency.

I am not too concerned yet. Because these are in vm's, I do a snapshot before any significant change. I can futz around with impunity because I have that backup.

I re-booted, and tried the apt-get dist-upgrade again with same results. I think I also tried apt-get -f install.

So I reverted to the snapshot, and will simply try again in the future. I recall that with lenny as testing, the font-desktop was really screwed up for about a period of 6 weeks.

However, just in case someone else runs into this:

1) a re-boot worked, but the failure of apt-get made me nervous enough to revert.

2) waiting for corrections has seemed to work in the past (with a single exception with a 4-disk SCSI software RAID10 update that failed to re-boot lenny successfully after what seemed to be a minor update -- that was on a real system, not a vm. I haven't gotten back to look at that.)

Debian Configuration :: Configure Multiple NIC's?

Jan 26, 2011

I have a Debian server that had only one onboard NIC (1000 Gbps) but now I've added two PCI Intel Pro 1000 NIC's into the system to bump up the total # of NIC's to three. My question now is can I specifically assign or force Debian which interface to configure as ethx? I would always like my onboard NIC to be 'eth0' and the two additional NIC's to be 'eth1' and 'eth2'. For some reason Debian loads the modules at random and sometimes what was my

Debian Configuration :: KVM / One Interface / Multiple IP Addresses

Dec 27, 2015

I'm renting a server which comes with 5 IP addresses, but only one network device. From what I can understand I'm able to create aliases by adding entries to /etc/networks/interfaces, I haven't tried I'm in the planning stages. Hypothetically, 192.168.22.30 is my primary IP and I want to set eth0:1 to have 192.168.22.31, and then after that I want to create a virtual machine (using kvm/qemu) that is able to communicate bidirectionally to the internet over eth0:1, and leave eth0 strictly for administrating (not for VM traffic).

The qemu guides I'm finding seem to assume that I want to use TAP or VDE, what I want to use is a sub-ip/alias. One guide I saw had me eliminate everything from eth0 and put it under br0. That would leave me unable to ssh into my server (and unable to administrate). Is there a way I can do something along the lines of: qemu [options] -net [option] -netdev=eth0:1 ?

Debian Configuration :: DHCP For Multiple VLANs

Feb 7, 2016

I'm trying to setup a DHCP server that serves several different VLANs, we have 5 in total. Our network is working correctly, with static IPs, we're able to ping across without any issues.

When I connect my debian box to an interface on VLAN5, statically assign an address in the correct range, it works. Similarly with all other VLANs.

To configure this box as a DHCP, I set one of the ports on the switch as trunk, connect that to the debian box to allow all VLAN traffic to reach my debian box.

I setup DHCP following the steps on [URL] ....

Then I configured different VLANs by following the steps on [URL] .....

However, with the vlans setup, I am unable to ping anything. This is essentially what I did.

Code: Select allSet the port on the switch to trunk with 802.1 encapsulation
disable eth0
vconfig add eth0 5 # to add vlan 5
ifconfig eth0.5 192.168.5.254 netmask 255.255.255.0 up
vconfig add eth0 5 # to add vlan 10
ifconfig eth0.5 192.168.10.254 netmask 255.255.255.0 up

[Code] ....

I do not know why I am unable to get any connectivity through my VLAN interfaces.

Debian Configuration :: Using Spamc With Multiple Files?

Jul 27, 2011

I have several mails which I want to scan by using spamc and thats the problem.

It works when I use just one mail message as a parameter of spamc. E.g. spamc -c < 17383. BUT when I want to pass several messages on spamc e.g. spamc -c < 17383. 18974.(spamc scan just the first message) OR when I use a whole directory e.g. spamc < ./test/* it doesnt work. (output: -bash: ./test/*: ambiguous redirect)

how to pass multiple files in command line on spamc? I know - I can create a script, but I would be glad if it worked for testing in CLI (command above).

Debian Configuration :: Correct Way To Start Multiple Instances Of MPD?

Mar 18, 2010

The first thing that comes to my mind is to add (copy) the script in /etc/init.d and the /etc/rc* directories by hand. Debian's automatic handling of init scripts on package install/removal is quite nice, so I tend to shy away from making any manual changes if there's an automated way to do it. Which leads me to the question: is there an official way to run a second instance of a daemon? (Tried google, didn't find much more than a bug report).

Debian Configuration :: Multiple Network Interfaces With VirtualBox?

Mar 29, 2010

I have a rather urgent problem with my network, I got two virtual network interfaces one internal and one external. The problem is; I can't get connection to internet. The external NIC is set as a NAT and the internal is... internal.

/etc/network/interfaces
auto eth1
iface eth1 inet static
address 192.168.1.200
netmask 255.255.255.0

Running with this configuration makes my internet connect go away, however if I remove the configuration for eth1 everything is working fine.

Debian Configuration :: Preventing Multiple Instances Of User?

Sep 6, 2010

Currently, a user is able to log into multiple terminals simultaneously, creating a copy of their roaming profile on each, and potentially causing problems if the instances are logged out in the wrong order. Is there any way to prevent this, so that if a user has logged in on a machine and not logged out (and perhaps some timeout has not yet expired) then their login attempts on another machine will be rejected.

Debian Configuration :: Wireless Networking For Multiple Users?

I have 2 users on my HPmini 210 netbook running Squeeze. I just found out that it does not connect to existing wireless networks when I login as the second user. Is it supposed to happen by default or am I supposed to do something to make that happen? Another problem is that when I tried to create "new connections" again for the second user, the keys won't work. The same keys are working for the first user. The network keys are WEP 64 bit HEX.

Debian Configuration :: CUPS And Multiple Printer IP Numbers?

May 29, 2011

Our Canon MX340 printer is WiFi connected using an IP address. This works well except that whenever the printer is turned off (for any reason) it chooses another IP next time it is turned on. As near as I can tell, it has two IP numbers: 192.168.1.64 and 192.168.1.65 Is it possible to enter both in the CUPS configuration so that CUPS will find the printer whichever number it is using?

Debian Configuration :: Jessie Nvidia-settings Multiple Monitors

Aug 30, 2015

I've always used Debian with a single monitor and no need of proprietary drivers, because I usually don't do graphics or multimedia. Now I'm asked to set-up a machine with 3 nvidia video cards (770) and 4 monitors and everything went south. I started with just 2 monitors connected to 2 different video cards, not wanting to push my luck.

I installed a fresh Jessie and followed the instruction to install the nvidia drivers and tools from the Wiki. Everything went smooth. After reboot I executed (as root) nvidia-settings and I configured the two monitors to be one to the right to the other, with BaseMosaic option (at this point just one monitor was active) I saved the configuration to /etc/X11/xorg.conf , I even executed nvidia-xconfig as suggested, I rebooted and nothing happened, only one monitor was working, while the other -- looking again in the nvidia settings -- was still disabled.

I then tried with xinerama option and things are even worse, since now both monitors are black. I can login in one textual shell, but then I don't know what to do, since in my 10+ years of linux ... I never had to mess with X server. Is there a way to at least recover a working X without reinstalling everything?

Debian Configuration :: Multiple Gateways / Firewalls Pointed To One Interface?

Apr 4, 2016

I am having some troubles using iptable rules on two Servers that act as Gateways pointed to one backend server with only one interface.

To be more exact, i have 3 Servers, 2 of those have a public and a private interface, with different public ips but common private interface ( they connect to the same switch ), the last one only has 1 private interface and is connected to that same switch.

Those 2 servers also act as a gateway and a firewall for the private network.

My problem is that i cannot seem able to route traffic from both of those to the third one and back to the same public ip that the request came from ( effectivly using two gateways on the machine with only one interface ).

As a testing scenario i am using ferm for applying iptable rules that forward ssh traffic ( for example ) to the backend server, and it works well when i do it with one gateway.

When i apply something like this in /etc/network/interfaces on the backend server though:

Code: Select allauto eth0:0 eth0:1
# The primary network interface
allow-hotplug eth0
iface eth0:1 inet static
   address   192.168.9X.XXX
   netmask   255.255.255.0
   broadcast 192.168.9X.255
   network   192.168.9X.0

[Code] ....

Even though forcing selection of an interface from the backend server ( like curl --interface ) seems to work well, meaning that the request to the curl appear to happen from the correct public ip, i can still only use one of the public ips to access the server with the ferm rules. Ideally i should be able to ssh to the backend server from both public ips using their ferm rules for forwarding traffic to the backend server.

I feel like i am missing some details on routing that should happen on the firewalls as the backend server seems to be able to use both gateways to access the internet and receive replies from it.

Debian Configuration :: Multiple Virtual Servers Be Setup In 2 Desktops?

Jun 12, 2010

I now have 2 desktops running debian. I have virtual servers running in desktop 1, and I am hosting my photos using Gallery2. I have copied Gallery2 and the mysql over to desktop 2. I have entered port forward to desktop 1 using port 80 (using my router), and desktop 2 using port 1000. I can only access Gallery2 in desktop1. If I tried to access Gallery2 in desktop 2, I got re-directed to desktop1.

Questions:

1. Are home routers capable of port forward to more than one computers in a home network behind the firewall of the router? It is Belkin N+ router.

2. Can multiple virtual servers be setup in 2 desktops?

Debian Configuration :: Custom Multiple - Boot Troubleshooting-System?

Aug 16, 2010

I want to build a custom system and I need your opinions. I have an old laptop which I want to configure as a system for troubleshooting purpose, my idea is to have multi-boot system with multiple root file systems, e.g. one root file system has only BIND to work as DNS server, another root file system has only Samba, etc., and I can choose which system to boot into from grub, or a custom menu after booting grub.

I thought of setting multiple partitions and install a full system on each one, but I thought that there might be a better way to do this, I'd like to hear your opinions.

Debian Configuration :: Samba: Sharing A Folder With Multiple Groups?

I want the unix group trustees to have read-only access I want the unix group administrators (and root) to have read/write access

All other users should have no access.

the implementation I have so far is:
folder owner: root:administrators

However, this is not working as expected. It currently works as follows:

Normal user: No access (expected) Trustees member: No access (fail. Trustees should be able to read) Administrators member: Read/write access (expected)

Debian Configuration :: Setup Multiple Mac Address Over Single Ethernet Interface?

Jul 23, 2015

I want to configure multiple virtual ethernet interfaces over a single physical ethernet interface (eth0) and for each virtual interface the MAC address must be unique and the IP address must be Static.Finally all the virtual interfaces must be able to communicate both internally and externally and the traffic should be captured using wireshark.

I need to have such kind of setup to communicate devices individually using one physical ethernet device.

Because I was fiddling with few kernel modules like MACVLAN and MACVTAP and successfully enabled those modules and rebuild kernel. Using macvlan and macvtap I can configure virtual interfaces with unique mac address and static IPs but while capturing packets using wireshark interfaces behave weirdly.

For example say on HOST machine I have 1 physical interface and created 3 virtual interfaces as shown below.

Interfaces :

eth0 (physical ethernet interface)
IP: 192.168.A.A
MAC: aa:aa:aa:aa:aa:aa

[Code] ....

First from above interfaces I started pinging eth0 internally from host machine in which it worked as usually.

Second I did same externally from other machine which is connected to the same network of Host machine, and this did work as usually.

Third I pinged first virtual interface veth0 both internally and externally and this also works and after that I did check source and destination MAC address using wireshark tool-where both showed up there respective MAC address.

Now triggers the issue, where I pinged second virtual interface same like I did for first one, but this time ping was success and where as in wireshark tool the MAC address for veth0 is picked by veth1. This is where I got stuck and this issue happened for all the remaining virtual interfaces.

I couldn't see any virtual interface showing their respective MAC address, as of the remaining except the first virtual interface has been picking the first veth0 mac address.

Debian Configuration :: Multiple Partition Setups Other Than Resistance To Data Loss In Crashes?

Feb 25, 2010

What are the advantages of the multiple partition setups other than resistance to data loss in crashes? Is there any other reason to have a special partition just for your boot directory (kernel files and config) than surviving a major crash?

Also, is it possible to make the Debian installer accept an existing set of partitions? Or even alter the size of the automatically created partitions? Does expert mode let you control the partitions? How many other very detailed things would I have to know to use expert mode, though?

Debian Configuration :: Need Kernel Between 2.6.26 And 2.6.32

Dec 7, 2010

On Lenny, due to some compatibility issues: kernels before 2.6.26 don't recognize part of my vaio laptop's hardware, while the last drivers of my videocard (version: 260, card: nvidia gt 230m) suffer some incompatibility problem (this is one of the most problematic computers I ever had), so I have to use version 256, which doesn't work with kernels after (perhaps) 2.6.32. So, I suppose I have to check each kernel between that two versions and hope that one of them will be ok. I searched quite deeply over the net but didn't find anything related to debian, except for generic kernels [URL], but as someone told me that it's better if I only install stuff from the stable repository or backports. What can I do? Is there any backports archive or something like that? Otherwise, what should I do?

Debian Configuration :: Add New AMD PCI-IDs To Kernel Module

Jul 9, 2015

I recently bought an AMD R7 360 videocard and I'd like to use the free Radeon driver.

Problem is, PCI-ID 0x665f is not present in Jessie's 3.16 kernel sources. The hardware however is supported, it's just not recognized. So I'll have to get the Debain sources and patch include/drm/drm_pciids.h

From the 4.1rc1 kernel I know what to patch and where.

I have a MyBookLive where i installed a Debian 2.6 kernel. The system is running fine so far. Because of an error message when apt-get upgrade (udev) i tried to upgrade to 3.16. Here's what i did:

- apt-get install linux-image-xx
- apt-get install linux-source-xx
- extract the source
- copied the old .config from running 2.6 kernel over to the 3.16 directory
- make oldconfig
- make uImage
- make modules
- make modules_install
- copied uImage to /boot

No error messages because its a headless device - its just not booting up.

Debian Configuration :: Kernel For Virtualization ?

Apr 12, 2010

I was wondering if anyone can assist me. I am looking to build a server with Debian as the host. When I installed Debian (Squeeze) the default kernel was "2.6.32-3-trunk-amd64". When I tried to install 'Virtualbox' application, I got a failure because I didn't have the 'kernel-headers' installed on my machine. I noticed there are no specific header package the 'trunk' kernel I was using. I have a few questions so I guess I should begin:

Is it safe to remove the 'trunk' kernel and boot my system on just the regular 2.6.32-3-amd64 kernel? Is this OK or not recommended? Please explain whatever is the correct answer. This is my 1st time using a 'Trunk' kernel so I don't know the in's and out's of it.

If I am using Debian 'Testing' for virtualization via 'Vbox', is there a specific kernel I "should" be using?
