View 10 RepliesIf I use static TCP configuration, (my Linux is Red Hat, but SuSE is quite similar) I define DNS's in file "/etc/resolv.conf" and Default GateWay in file
"/etc/sysconfig/network" (/etc/sysconfig/network/routes undef SuSE).
So, when I want to display those values, I just display the contents of the file. But, if my TCP configuration uses DHCP server ... I dont know the command to display those values. PD.- in straight : I need a command to display the DNS's in effect on a TCP/IP configuration that uses a DHCP server. Also, a command to display Default Gateway would be welcome.
when i assign ip manually to a machine it gets ping by server and it also itself pings server but when i chose to use client machine as dhcp , so that it can directly get assigned ip from server, it does not get ip, instead random ip is provided which is out of range specified at server side in /etc/dhcpd.conf file.
View 2 Replies View RelatedI have a network consisting mostly of Windows Vista and 7 clients and an Ubuntu server. The server provides both the DHCP and NTP services through dhcp3-server and openntpd. In my dhcpd.conf, the subnet is declared as follows:
subnet 10.10.10.0 netmask 255.255.255.0 {
range 10.10.10.10 10.10.10.200;
option broadcast-address 10.10.10.255;
option routers 10.10.10.1;
option ntp-servers 10.10.10.1;
The clients don't seem to be using the NTP server though. When I capture the network traffic with Wireshark during the DHCP process, I also see no mention of the NTP option in the DHCP offer message. I am not quite sure if the clients would have to specifically request that option to receive it or if I have to make another configuration to offer the option.
I have two servers behind different networks. First network is protected with firewall provided by the router and there is no firewall in the server:

As you see, there are no difference in nmap output If I check with tcpdump, which packets are sent from 192.168.217.73 and 192.168.13.19(tcpdump -i eth0 src host 192.168.217.73 and tcpdump -i eth0 src host 192.168.13.19 respectively) towards me during nmap scan, there are none. It's understandable, as there should be no reply when port is filtered. Is there somehow possible to detect, whether firewall is active in the server or in the router?
How do we configure to resolve for hostnames when an IP address is provided to the DNS server.
Things I tried
The DNS daemon was started by the resolution failed. Find the logs below
** server can't find 11.127.168.192.in-addr.arpa: NXDOMAIN
Is there a way to get the current time as provided from NTP (not the currently set time on the server)?

I have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?

The computer is an older model but I'm unsure of the brand, the motherboard is Intel entry server S845WD1-E. Recently his mouse stopped working, then his keyboard. I am going to try a ps2 card (the ps2 is internal to board). We are unable to use a usb mouse or keyboard. I have installed a new usb card but that did not work. I've tried different memory but have not run memck on it with another computer. After trying several suggestion from various support sites, including Intel, I finally cleared CMOS, removing the battery and then reset jumpers. Now I can enter Setup, but of course can't use the keyboard to change the settings in BIOS. I want to load CD-ROM first, but can't access via keyboard to change. I suspect the motherboard is going out, but still have hope. This couple is elderly and fixed income so I'm trying to milk it for all I can. I can use his HD on my system just fine.
View 1 Replies View Relatedhow to change the value of the inputs in sed while looping
As such:
for i in `seq 1 10`; do
"do something funny, using OpenFOAM"
cd system
sed 's/oldvalue/oldValue+increment/' -i sampleDict
cd ..
done
So basically, can you for instance create a constant "a" and increase it for every loop interval and use it for sed?
I'm running Ubuntu Server 10.04 to provide DHCP and Internet Sharing on my home LAN. In a previous configuration, I was running Fedora + AMAHI to provide the same services. As most of my linux devices are Ubuntu, I decided to decommission and rebuild my server. I've been able to configure all of my services with the exception of one. As a rule, I assign static IP or reservations based on MAC address's for any of my network devices or appliances.
One cool feature that AMAHI provided a GUI for, was the ability to recognize devices by name as well as IP. i.e.. "http://192.168.1.50" or "http://home-NAS" Going from memory, the long name upon first entry may actually have been "http://home-NAS.adomainname.com"? From my reading, I think I either need to setup up a Static Alias or CNAME for each assigned IP. I can't find any tutorial's that will walk me through this process. I'm guessing I need to generate the records under one of the master DNS zones, but that is just a guess?
I have an idea to install a video-camera to record 24/7 the place in the yard where the car will be kept. Can not say that I'll configure such a system for sure, but I have an interest to it. On the other hand I've never worked with such systems and I don't know what cameras are better, should they be IP-based or the USB-webcam will be OK, I also do not know much about the software. I've found that gphoto is a good software for such a purppose, and some photo-cameras can be managed remotely through console, I mean that we can take pictures/?video?
Remotely, if the camera is connected to the Linix-box via USB. Another soft, which I googled, which (as I understood) is de-facto and which is powerful, is ZoneMinder. Today a friend of mine told me that many IP-cameras have everything inside them (a webserver, many tools for capturing video/photo and so on), so I just need to create some directory on the PC, where it will store all photos/videos. So, as you see, I know practically nothing about all this. That's why I decided to listen to you, what software and photo/video cameras would you recommend me.
