Fedora Networking :: Resolving Host Names To IP Address ?

Jul 27, 2010

At work we run DHCP. hostnames have the format: computername.city.mycompany.com

I have a laptop runing Fedora 13 and a desktop I use for backups, etc. My laptop is named copernicus. Desktop is named galileo. If ping either hostname from itself I get back the localhost IP address. If I ping the fully resolved hostname it tells me unknown host. The desktop is exporting an NFS share I use for backing up work data. I need the laptop to be able to resolve host names to mount the share since we use DHCP. The desktop is dual boot and if it is booted into windows my laptop can resolve the hostname properly. What do I need to do in Fedora to get it to register a hostname with the DNS and/or DHCP server? Should the domain and the search path below both say the same thing?

Here is resolv.conf on the laptop (I am at home). The desktop looks the same, except for a different nameserver. Both computers can resolve other hostnames, just not each other.

Programming :: Small Java Program To Manage 2 Apartments?

Feb 17, 2011

this is my first post and I would like to get some help from you , so what should be the answer for this question ?:::::::::::::the question::::::::::::::::THE UNIVERSITY APARTMENTSThe University Apartments provides apartment rental to university students at affordable rates, with optional facilities:Apartment Type A, 2 bedrooms and equiped with kitchen and laundry facilities. The monthly rental for the rooms in this apartment type is RM300.Apartment Type B, 3 bedrooms includes one master bedroom with attached bathroom but does not have kitchen and laundry facilities. The monthly rental for the rooms in this apartment type is RM200 and students staying in the master bedroom will be paying an additional 40%.

Each apartment may house a maximum of 3 students. Students are required to check out from the apartment unit when the current semester ends.Create an application to manage the university apartments rental:1. Register new student and assign apartment moduleRegister and assigns an apartment to the student for 140 days from the date of registration. The module should retrieve the date automatically from the system clock and calculates the expiry date for the apartment rental. Before an apartment is assigned, the system should allow the selection of the type of apartment (i.e. Type A or B), then check for the number of occupants in the apartment. If the apartment already housed 3 students, it should recommend another apartment unit that is still available. Upon registration, student should pay a RM100 for the utility charges, rental deposit for one month and the rental for the current month.

2. Update apartment status moduleWhen a student moves out from an apartment, the apartment status is updated.3. Reporting moduleGenerates a report of apartments with full occupancy and another report for apartments where rooms are still available. 4. Search module Enable the administrator to search for a student's apartment unit using the student id as the search key. The search result should produce the student�s information and the details of the apartment that the student is staying in.The application should be developed using object-oriented concepts using Student class and Apartment class, implementing the appropriate data fields and methods for the classes. Data may be stored in collections i.e

Debian Programming :: Memory Usage When Running Java Program

Jun 28, 2013

I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.

However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.

I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.

Programming :: Using Java Runtime - Program Which Simply Calculates The Load Average Of A Process

Feb 10, 2011

I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.

I'm building a replacement service, and in the not to distant future, I'll need to change the host name and IPs (ipv4) (I'll also be doing this on the fedora 10 box I'm replacing)

I can look around and edit a bunch of files to make it happen, but there has to be an easier way.

Ubuntu Networking :: Assigning Host Names On LAN?

May 29, 2011

when I'm in my campus I saw things like this from tcpdump:

client-64-15.department.univ.edu
client-x-y.department.univ.edu
gw.nettokurabu.univ.edu

and my laptop got a name like that too (x and y being last 2 segments of the IP)out of curiosity, how to assign names like that to each IP? well, the names are not in dns records (can't resolve them to IPs)... when I set up (illegally) my on subnet with a routing software the addresses I used also already have their name without me configuring it before...

OpenSUSE Network :: Host Names Cannot Be Resolved Except For Ping

May 5, 2010

I'm running openSUSE 11.2 (Linux piura 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux) and have a network problem. At work, ethernet works fine. When I plug it into my DSL router at home (which works with other computers), I encounter the following behavior: ping can resolve host names, however, traceroute and Firefox and Thunderbird cannot.
It happens for both wired and wireless connections.

General :: Get Windows To See Host Names And Vice Versa?

Sep 17, 2011

I have Windows and Linux machines on the same subnet. My router configuration correctly tells me both their machine names, and their IP addresses. However, when I try and ping a Linux machine from a Windows machine, or ping a Windows machine from a Linux machine, I need to use IP addresses rather than names. If I'm pinging a Windows machine from a Windows machine, or a Linux machine from a Linux machine, the machine name correctly resolves without any hosts file entries. Why is this?

I would have thought my router (D-Link DIR-655) would act as a DNS server itself. I see it has an option called "Enable DNS Relay", but from what I've read this won't help me. If it's relevant, the DIR-655 is used for internal traffic, with my ISP's Netgear DGN1000 used as a gateway to the Internet. It's on a different subnet though, and all my machines connect to my DIR-655, not the DGN1000. What do I need to do to have host names automatically resolved within my subnet regardless of the operating system that they're running?

Networking :: Internal Host Names Resolving Through External DNS?

Feb 6, 2011

I just set up my first ever bind9 DNS server running on ubuntu server 10.04. This server is also my gateway/dhcp server.

Here is what is weird: If I do a dig @8.8.8.8 dschuett-lmtl.scs.local from any of my clients it resolves?!?! Dig shows that it got the answer from MY Bind9 DNS server (and NOT Google's of course), but why is it still resolving when I'm telling it to use and external DNS server?

The other weird thing is that the SAME EXACT dig command above does NOT resolve internal host names if I do it from the Bind9 DNS server. - Which is what i would expect SHOULD be happening if done from the client machines...

Here are the dig results:

From any internal client:

Server :: DHCP: Logging Host Names In Log File?

Jul 7, 2009

What I am trying to do is log IP Address, MAC Address and the host name for records. So I can have a record of what PC got which IP address and when they got it. So far my search has yielded no results. It would not be that big of a deal as I could always look at the dhcp file, but it is generated dynamically (3rd party application using RADIUS and each user gets a host).

subnet 208.x.x.0 netmask 255.255.255.0 {
option routers 208.x.x.1;
option subnet-mask 255.255.255.0;

CentOS 5 Server :: Name Resolution Of Host Names Using Bind?

Mar 21, 2011

I installed bind & did not install chroot. I set up a fictional domain kelly.local. I am able to resolve FQDN (example: angus.kelly.local) in both dig & nslookup & ping on linux boxes.

I want to be able to resolve bare host names (example: angus) using bind. I get mixed results.

(1) linux boxes resolve bare host names & FQDNs just fine using nslookup & ping, but not dig. dig gives error:

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> angus
;; global options: printcmd

Networking :: Multiple Domain Names On One IP Address?

Dec 19, 2009

Is it possible to have one static IP address with a NAT network forwarding each domain name to certain internal/DMZ IP addresses? I know you can do it by port but if both websites are on port 80 can you forward to the corresponding server on the dmz.I ask this because I noticed the website braemere.com.au had to be typed into a web browser and entering the IP which is 202.47.5.7 did not take me to the website.

Server :: 2 Websites (domain Names?) 1 Cup Err Ip Address?

Dec 13, 2010

So I'm looking to host potentialy three different...sites...I want to call them from the same machine. One is a radio station and the other 2 are just straight websites. So I wanted to know if I had to use different machines to accomplish this or can I alter maybe the http conf file or what. I did find this in the forums but wasn't quite sure if this applied to me.

Fedora Networking :: Local Host Names Without Domain Using Bind?

May 10, 2009

I want to use single label host names on my local LAN, without using any domain (at least no registered one). My machines should be named in a fashion similar to 'myserver', 'mydesktop' etc. so that i from a browser on any LAN machine may write 'http://myserver', and get the webserver on 'myserver' (so NO domain part, e.g. myserver.domain).

Do i need to create a DNS zone for each host or is there a way to put all host in a single zone, if so; which? Would such a name be considered a root domain?

CentOS 5 :: Configure Sendmail To Accept Email Without Domain In Local-host-names

Mar 23, 2011

dammit... all that typing and I hit the wrong "submit" button. *sigh*

Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.

SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
