I boot some Slackware with PXE. All work fine except i can't fix the client lockd ports.NFS is compiled inside the kernel, so all modprobe.d options are useless.But rpcinfo -p on the client side shows me totally different ports.On the NFS server, the ports are ok, as i appended lines in /etc/lilo.conf Server and client kernels/modules are identical.
View 1 RepliesI have a simple home network with a windows and fedora clients. I'm running fedora 13, but I"m having problems connecting to the pc on certain ports from my windows pc. I can connect from windows to fedora using VNC, and even connect to my postgresql database. However, can not get connected to my Apache Tomcat or JBoss server. When I first installed the OS I went through and configured the firewall but have since disabled it (stopped service). However, I still can't get to the app/web servers.

My first atempt is to restart the NFS, but locked files persist because I can kill the lockd pid process, even using root account , I suppose this is because it's a kernel process. Here is the message error I get when restarting NFS matrix kernel: lockd_down: lockd failed to exit, clearing pid
Our router is pretty old and only capable of giving fixed ip and there is no support for IPv6. Via the gnome networkmanager I try to set a manual IP to 192.168.1.123 and a netmask to 255.255.255.0 and a default gw at 192.168.1.1 . However, this does not work.
If I open a terminal and type:
Code:
sudo ifconfig eth0 inet 192.168.1.123
sudo route add default gw 192.168.1.1
Then I get a perfectly valid connection to the internet.
ifconfig by it self returns:

ffor me it seems that the gnome network manager doesn't save the information that I gently ask it to.
I can fix it with the CLI commands, but I would like to know whats going on.
For some time, I've had DSL and used Fixed-IP internally. I moved, no DSL, no cable, no nuthin' but dial-up and flaky cell-phone modem. Ugh. Along comes American Recovery and Reinvestment Act providing funding for making high-speed internet available to those of us in the boonies; no up-front or monthly equipment costs, affordable monthly changes, whoo-boy, that's for me. Installed, works, bada-boom, bada bing.
I have three servers, a network printer and a large format pen plotter that have all happily played together with fixed-IP for years connected via a Linksys BEFSR41 router and CAT-5 or CAT-6 cables and I do not want to screw around with DHCP (and the printer and plotter don't particularly like DHCP in any event). The servers talk to each other with SSH, their names and addresses are in /etc/host and all has been well with the world. DSL connected with PPPoE, HughesNet connects "automatically" to the modem with DHCP. I also have a switch available for additional LAN stuff as needed. Of course I had to do a hard reset of the router when setting up HugheNet (right back to infancy).
I do need to have DHCP enabled in the router for the limited occasions that a Winders thing gets connected to it (not my box, I don't mess with it).
Now, the actual question: is there any setting in the router that will enable fixed-IP, ignore DHCP leases unless the server is running DHCP (like a Winders box) and not bother me with screwy lease addresses that override my fixed-IP addresses? My servers are running Slackware 13.1, all configured with fixed-IP, all configured to "know" each other via /etc/hosts, /etc/resolv.conf has DNS Server address in it (and DHCP is not permitted to overwrite /etc/resolv.conf.
Assume I installed originally CentOS Desktop with IP receiving from DHCP server.Later I decided to assign a fixed IP to the local CentOS installation.How do I switch (permanently) the dynamic DHCP IP assignment to a fixed IP?

I have scoured the Internet for answers, and have seen several people with the same problem, but no solutions that work for me. I think it may have something to do with the driver. I really do apologise if this has been answered properly several times, but none of the solutions seem to be working in my case.
When I install Fedora 10 on a new system, I let it default to DHCP. Later, I change the system to a fixed IP address by running system-config-network, selecting eth0, clicking on "Edit", clicking on "Statically set IP addresses:" and filling in the blanks. Is it possible to accomplish the same thing using commands that could be entered in a script? I assume one of them would be
Code:
ifconfig eth0 address XXX.XXX.XXX.XXX netmask 255.255.255.0

I'm on 11.04, im on a macbook 6,2 i7. The wifi worked when i booted from cd but now it doesnt work once i installed.
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface
auto lo
iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?

I have a number of diskless hosts which are to bootth PXE and mount their root filesystem on an NFS share. Most of the NFS share will be common to to all of the diskless hosts. No problem with that part.I also need part of the NFS shared filesystem to be unique to each individual host. The only difference between the hosts is the ethernet MAC. I use it in the DHCP server to key a specific unique IP to each host. I would like to be able to use either the MAC, or the IP, or any other unique identifier that can be derived very early in the boot process to access a filesystem or directory that is unique to each diskless host.
I need/want to do this because I need/want to isolate all of the system maintenance to one small part of the boot host. Modifying the hardware (these are VME CPUs) in any way is not an option; they must be field swappable, with all maintenance isolated to the boot host(s).I know I could run ifconfig and parse its output to derive an IP &/or MAC, but that seems a bit kludgey and fragile. The DHCP server is presently assigning IPs. I know I can arrange to pass a unique option value via the DHCP server, but don't know if or how this can be retrieved on the diskless nodes. I am presently passing the 'root=' kernel argument from the bootloader, but I don't think there is any way to pass other filesystem information using that mechanism.
I know I can pass some kernel arguments from the bootloader, but there doesn't seem to be any generic message that can be retrieved in userspace as part of the boot process. I've scanned around in the /proc filesystem, looking for the IP or anything else that seems to uniquely identify the host, but don't see anything there, either.The init process has not yet been cast in stone, but is very likely to be a BusyBox built-in

View 2 Replies View Related5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?
It seems with the newer linux headers, two functions changed their names slightly and caused a crash when attempting to build the Asus-provided USB-N13 drivers.
I'm still in the middle of getting the device to work, but actually compiling the driver was a major problem for me and others I've seen that complained of the breakage in 10.10.
Here's the fix:
Within the include/os/rt_linux.h and os/linux/rt_usb_util.c files, the usb_buffer_alloc and usb_buffer_free functions are part of an internal macro. These functions do not exist anymore and are replaced by the usb_alloc_coherent and usb_free_coherent respectively. Input parameters did not change, just the names.
The macro is defined in rt_linux.h and the functions are used in a symbol export within rt_usb_util.c. Simply renaming the functions should allow it to build.
As I said, I'm still in the process of getting the wireless to work, just wanted to let everyone know of the quick fix.
This issue will probably be addressed with a macro fix somewhere eventually.
#define usb_alloc_coherent(a, b, c, d) usb_buffer_alloc(a, b, c, d)
#define usb_free_coherent(a, b, c, d) usb_buffer_free(a, b, c, d)
I 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.

I originaly tried with Redhat 9 and had the same problems. I am using an HP Pentium 4 system with 2 network cards.
1) The built in Realtek RTL8139 configured as eth0.
2) An add in Broadcom BCM5782 Gigabit card that was added I presume when the built in card failed (we have a number of machines like this around the school), configured as eth1.
I did not realize the second card was installed when I had Red hat 9 on the system, but I discovered it after installing centos 5.5. I have tried to configure the system to use DHCP with and without getting the DNS from the provider, and both ways the system complains that there is no connection, check the cable, so it will not activate the device.
When I configure the device to use a fixed IP, I can configure the device, but I can't ping anything on the network other than myself. I suppose it is possible that both network cards have failed, but I get green link lights with both cards, when I connect them to my router, so I am at a loss as to why neither board seems to work. I don't have a spare network card to slide in because the computer takes a special mini card. Is there an easy way to test the board to see if the board is a problem?

Here is an overview of my system, consisting of two computers, a D-Link router and a ZyTel 660 DSL modem/router. Computer One (Comp1) is dual booting XP and Ubuntu 8.04. Computer Two (Comp2) is booting only Ubuntu 8.04. For years, I had been running and networking both of these computers with XP. Both have been using static IPs. In order to have Static IPs and forward certain ports, I had to configure the D-Link router as an Access Point and use the ZyTel as the defacto router for the network.
The Static IP info for the two computers is:
