Networking :: What Is Wrong With IP Configuration
Dec 24, 2009
acl accounts src 192.168.0.1-192.168.0.133/255.255.255.o
acl accounts src 192.168.0.135-192.168.0.254/255.255.255.0
acl full src 192.168.0.134/255.255.255.o
http_access allow accounts
http_access allow full
http_access deny all
delay_pools 1
delay_class 1 2
delay_parameters 1 9000000/9000000 25000/25000
delay_access 1 allow accounts
delay_access 1 deny full
delay_access 1 deny all
Well why all my ips are getting the speed I mentioned in delay pool, even 192.168.0.134, as I have excluded it in delay pool. what is wrong with the configuration. I want 192.168.0.134 to get maximum speed available, while rest of the network goes with the mentioned speed.

I recently installed another Linux distro, Kali Linux, alongside my Debian 8 and discovered to my chagrin that my computer boots to Kali's grub rather than to the Debian grub. I had spent some time customizing Debian's grub and would hate to see that effort go to waste. Is there a way I can get my computer to boot to Debian's grub instead? I tried deleting Kali's boot partition with gparted but that did not seem to do anything.

Today I fresh installed the latest stable version of debian (jessie) with gnome from the USB DVD image for a 64bit machine. Everything got fine except the graphic driver, I think.
Now Gnome 3 is running but graphic is super slow. My previous debian/gnome 3 ran much better and I think there is a problem with the graphic driver.
I'm on an thinkpad t61.
Processor: Intel Core2 Duo CPU T7500 @ 2.20GHz × 2
Ram: 4GB
Graphic: VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)
Now the graphic is: Gallium 0.4 on llvmpipe (LLVM 3.5, 128 bits) which is likely wrong. If I'm not mistaken llvmpipe is pure slow software acceleration.
Moreover this was different on my previous debian (wheezy), which was faster. Anyway I don't know what " Gallium 0.4 on llvmpipe (LLVM 3.5, 128 bits) " is and it was for sure different in wheezy.
According to apt-get I have the latest intel graphic divers installed. So maybe this an X-org confic problem?

A couple of days ago I asked why my pc changes the wireless card name.It switches between AR9285 ( right) and AR5008 ( wrong). Well, it is not the case. When system identified with AR9285,it loads ath9k and I can connect to the router. When system identifies my card as AR5008, no kernel module is present at all ( lspci -k). The wrong card name occurs only when system rebooted. If I gracefully shut down the system, it always comes up with a right name for the card( AR9285). So, how to force the system identify my card right no matter if I reboot or shut down?

I've been working on the setup of a FTP server on my Debian system for the whole afternoon. But I can't get it straight! Normally I get it working in just a second, but it's been a while I guess.
I installed only proftpd-basic and it's default dependencies. Should be enough right?
My configuration files are as follows:
I created the user zeitgeist, gave it a password, group and a homedir. Group of the user is nogroup and the homedir is correct with the 755 permission. My port 21 for FTP is open I tested it with nmap -p 21 [ip-address].
My Filezilla client tells me that at first he is connecting, then the connection is established, And then the connection is closed by server.

I've got a strage problem with openssh-server on debian lenny. I've done setup of sshd and basically everything works fine. I can check the fingerprint of the ssh-keys on the server and it matches with the fingerprint shown on the client for the first connection. so the key is stored in the known-hosts-file on the client.
The problem occurs after a "connection reset by peer" (i guess when the connected client goes to sleep or a timeout occures)!
After such a reset, when I try to connect to the server, the banner "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" appears and the shown fingerprint of the server-key is totally wrong (it differs from the one on the server, BUT it is everytime when this problem occurs the same fingerprint). If I nevertheless remove the correct key from the known-host-file and accept the new key, I still can't login (permission denied).
To fix this situation temporarily I just need to restart the networking on the server. After the network-restart I get (again) the correct fingerprint of the server-key and can login without problems. Until the next connection reset.

Hey guys. I have a client computer PXE booting from my host computer and it is supposed to give the client the ip address 172.16.0.100 however instead it gives it the ip address 172.16.0.208.
I have this set up working with two other computers and there is no noticeable difference other than mac addresses for the network card.
Here is an extract from my '/etc/dhcp3/dhcpd.conf' file...
ddns-update-style-none;
option domain-name "example.org";
default-lease-time 600;
max-lease-time 7200;
[Code]....
I have quadruple checked the mac address of the client and it is definitely "00:07:E9:32:16:81" so why is it not giving it the IP address that I have specified?

I have a peculular routing problem on my hands. I have a server running in my office. it has various services running on it (httpd sshd etc.) in order to access these services I have a domain name pointing to my IP.If I try to connect to the server from an external IP, all is fine and working as normal.However, if I am connecting from the interal lan to the server, my domain name resolves to the address of the routerSo for instance everywhere on the interent my domain name resolves to the correct external IP (12.23.34.45) which is then connecting through my cable modem (12.23.34.45) to my router (192.168.55.66) and directed to my server (80.80.80.80)however if I resolve my domain from within my lan, I get my routers ip 192.168.55.66 so trying to connect to my server times out while connection to the wrong device.My network setup is very simple. nothing fancy.I think I'm using google's 8.8.8.8 for my dns server

I updated Kubuntu from 8.10 to 9.04. After the update, I saw a problem with VPN connections. I am using an mac pro with 2 ethernet ports. Only one of them is connected to switch. I am using a static IP in my local network. The problem is that I lose dns information after connecting and disconnecting to a VPN by KVpns.As I am using static ip, I entered my dns server to resolv.conf file with "nameserver 192.168.128.4". My interfaces file is as follows:
auto lo
iface lo inet loopback

Let me explain: I had the 10.04 LTS Beta, and upgrading until today. I got the wireless card ( the notorious broadcom ) in the beta by adding the CD to the repository, installing through synaptic ( the broadcom drivers available from the CD ), then selecting the driver from the Hardware Device Manager, enabled, restarted and was online.
I thought the Final version would be just as smooth right? I didn't upgrade because the OS never showed up in the Beta's Software Updates, so I figured to just do a fresh install, my biggest issue with Linux in general was solely it's conflict with broadcom, never anything else. So anyway, In this Final Release, I go to do the same routine, check this out: The card wasn't even showing up this time, wasn't being recognized! In the beta, it atleast showed up. That's minor but would be major to a new guy.
I figured to do the synaptic again, add the cd then the b43cutter( i think it's called ) and succeeded, got the Card to show this time. When I went to add the other driver ( the bcmwl-kernel ) the file that would have the driver to be enabled, it tells me "File Not Found!" don't give me the cop out of "Hook it up to a cable modem and download the driver" bid because that just pisses people off, we don't all have the means to carry around massive PC's to a cable modem.
What I hope to expect is someone telling me to download a file and have it on the desktop then trying it that way because I know about all the other tricks, and I think you can see, I tried em. I'm curious to know why it worked in a Beta release and not now

While running some live tests last week I saw an odd situation where netstat appeared to be displaying the wrong PID and process name for TCP connections. I'm trying to figure out if this is just a strange netstat bug or if it could indicate something odd is happening with our software.
We have a main program which establishes a number of connections, including connecting to a JMS server and listening/accepting a TCP connection. The main program also creates a child process which it uses to communicate with another server. On at least three occasions we saw a situation we saw netstat reporting all the expected TCP connections (correct ip/port for both source and destination), however the child process, instead of the main, was listed for the PID. The main process was still running but netstat no longer reported any TCP connections established by the main program. The main program continued to function correctly, the JMS communication continued to work and we believe the other TCP connection was functioning correctly despite the program supposedly not having any TCP connections.
I'm wondering if this could simply be a bug and/or obscure functionality of netstat that I don't understand which would cause netstat to report the child process as 'owning' the parents TCP connections. I don't know how this would happen or why the parent would continue functioning despite the problem otherwise.

I'm trying to get dhcpd to use a specific IP address as the source address for responses it uses an IP address for. I coded "local-address 172.30.0.4" in the config file. For some responses it uses this address. For some other responses it does not. In those cases it uses the IP address that is the first on the interface. Is there another configuration I should be using, instead?

I'm not too sure if this is the right topic to post in but if it isn't please move it to the correct topic. I recently opened some ports for my Playstation 3 and the connection test on the PS3 tells me that the ports are open . But when I execute this command
nmap -p 0-60000 192.168.1.5 I get this
Quote:
Starting Nmap 5.21 ( http://nmap.org ) at 2010-10-16 20:54 AUS Eastern Daylight
Time Nmap scan report for PS3 (192.168.1.5)
Host is up (0.00063s latency).
All 60001 scanned ports on PS3 (192.168.1.5) are closed
MAC Address: **:**:**:**:**:** (Sony Computer Entertainment)
Nmap done: 1 IP address (1 host up) scanned in 4.12 seconds
I could be executing the wrong command or something but I have read through the manual and couldn't find anything that helped. I have tried this command on other machines that I have opened ports for and get similar results except for a few Ephemeral ports (80,443 etc.) which also makes me wonder why these aren't listed as open on the PS3?

I'm running a fresh install of Ubuntu 10.4.1 on a Dell Dimension 4700 desktop.When connected to the network (jack in wall, no router), I normally navigate my intranet and the internet.But here's the issue: this particular Dell machine has an IP addresses that is radically different from all other machines connected to the same network.I have tried to edit etc/network/interfaces to force a different IP, but then I lose connectivity. I need this to follow the IP scheme of my intranet so I can set up a server that resolves by hostname. Is there anything wrong with the NIC or is this something that can be resolved via command line?

yesterday a tried to put Ubutnu 32bit insted of 64bit to try differences, but I have a little problem with some web fonts For example on facebook are texts messed... and it is same on a couple other websites, which has nothing common. (School pages, wordpress administration...) Fonts are wrong in all web browsers, but each browser shows them different. for example Facebook in Opera (text is messed) and login page in Firefox(text is missing...) So i think, it is not a problem with browser.

On a server with 4 network interfaces, sometimes not all 4 are plugged in. All 4 interfaces have the same IP address. Sometimes the machine cannot access the local LAN, but can access the internet via a router on the local LAN, after a reboot. What I find is that the routing table looks like this:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2
172.30.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3
0.0.0.0 172.30.0.2 0.0.0.0 UG 1 0 0 eth0
0.0.0.0 172.30.0.2 0.0.0.0 UG 2 0 0 eth1
0.0.0.0 172.30.0.2 0.0.0.0 UG 3 0 0 eth2
0.0.0.0 172.30.0.2 0.0.0.0 UG 4 0 0 eth3
On the console I cannot reach any local host, but I can reach internet hosts. Pinging the gateway router 172.30.0.2 gets no answer. When I manually change it to this:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.30.0.0 0.0.0.0 255.255.0.0 U 1 0 0 eth0
172.30.0.0 0.0.0.0 255.255.0.0 U 2 0 0 eth1
172.30.0.0 0.0.0.0 255.255.0.0 U 3 0 0 eth2
172.30.0.0 0.0.0.0 255.255.0.0 U 4 0 0 eth3
0.0.0.0 172.30.0.2 0.0.0.0 UG 1 0 0 eth0
0.0.0.0 172.30.0.2 0.0.0.0 UG 2 0 0 eth1
0.0.0.0 172.30.0.2 0.0.0.0 UG 3 0 0 eth2
0.0.0.0 172.30.0.2 0.0.0.0 UG 4 0 0 eth3
Then all is well (can ping local hosts including the gateway router). I do have metric specified in the /etc/network/interfaces file like this:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 1
auto eth1
iface eth1 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 2
auto eth2
iface eth2 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 3
auto eth3
iface eth3 inet static
address 172.30.16.8
netmask 255.255.0.0
network 172.30.0.0
broadcast 172.30.255.255
metric 4
Apparently that metric setting applies only to the gateway route, not the LAN route. Is there a way to specify the LAN route metric, too?
