Networking :: Nslookup And Display All The Aliases For A System?
Nov 10, 2010Not really a linux specific thing I have gooled the heck out of it and tried nslookup -a and a few other options nothing gets me what I need. The question is I have a machine with several aliases in dns. How do I do a nslookup and display all the aliases for a system.
I am trying to see if something it aliased correctly but i cannot list all the names a system is know by.
I am sure its something simple I am missing with a switch.
Networking :: Nslookup Returns Connection Timed Out
Feb 4, 2011I am not so experienced with networking in Linux. I've successfully installed Red Hat Linux Enterprise 5.2 on a VMware host. When I issued nslookup command, it returns "connection timed out" error as follows:
Code:
[root@rac1 ~]# time nslookup rac1
;; connection timed out; no servers could be reached
real 0m15.038s
user 0m0.000s
sys 0m0.000s
My questions are:
(1) Is that error normal?
(2) Is there a way to decrease the 15.038s value? rac1 is the local hostname, so why it takes all that time to resolve it.
Following info may help:
Code:
[root@rac1 ~]# hostname
rac1.mydomain.com
[root@rac1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost

Ubuntu Networking :: Can't Resolve .local Domains Anywhere Except With Nslookup
Nov 29, 2010I'm finding that I can not resolve .local domains anywhere except with nslookup and found on the LucidLynx release notes that there is a problem with avahi causing this. Although the avahi service is convenient for locating printers and such can anyone else tell me what other services/options will be impacted on a default installation of Ubuntu if I disable this service?

View 4 Replies View RelatedNetworking :: How To Make Nslookup Return Failure If DNS Server Fails
Mar 23, 2011I'm trying to find a command to tell nslookup, "I want you to try to resolve hostname X using DNS server Y, and if the lookup fails, just output failure do NOT fail over to some other DNS server as a backup and use it to try to resolve the same hostname."I'm trying to follow the man page instructions for doing this, but it doesn't seem to work. The man page for nslookup on my system (CentOS 5.5) includes the line:
"[no]fail Try the next nameserver if a nameserver responds with SERVFAIL or a referral (nofail) or terminate query (fail) on such a response."But if I try using that option, the output seems to indicate that after the lookup failed on ns1.afraid.org, nslookup failed over to 208.67.220.220 (the first nameserver listed in my resolv.conf -- an OpenDNS nameserver) and used it to resolve the hostname instead.
Networking :: Nslookup Returning Multiple Names On RedHat With Windows AD
Jun 11, 2010Recently I installed RedHat Enterprise 5 on a windows machine. The machine is configured to use DHCP, but I have been seeing some strange behavior if I do nslookup on the machine's IP:
[someuser@lin01 mydir]$ nslookup 10.5.x.x
Server: 10.10.x.xx
Address: 10.10.x.xx#53
x.x.5.10.in-addr.arpa name = xyz.something.
x.x.5.10.in-addr.arpa name = lenovo-d1690047.
x.x.5.10.in-addr.arpa name = pqdlds.
x.x.5.10.in-addr.arpa name = lin01.mydomain.com.
Where only the last entry of [URL] is actually correct, how can remove the other entries? I spoke to my IT Manager and he cannot see these stale entries in the DNS (we are using windows AD)

Fedora :: Unable To Use Nslookup (get The Same Error With Dig, Btw)?
Jul 7, 2009Have Fedora 11 running fine on my multi-Opteron system - but have stumbled into a problem which *might* have some significance (since it might relate to other system functions).When I tried to use nslookup (get the same error with dig, btw), I get the following error message:nslookup: error while loading shared libraries: liblwres.so.50: cannot open shared object file: No such file or directoryMy *guess* is that this is a bind-libs error, but I'm brushing up against the extent of my personal knowledge-base on this one.

View 3 Replies View RelatedNetworking :: Net Command Gone / Get That Back?
Dec 27, 2010I have been using the net command for a while now to remotely shutdown my windows machine, I believe that it comes with the samba package.
"net rpc shutdown -f -I IP_ADDRESS -U USERNAME%PASSWORD"
I run a Ubuntu 10.10 x86 Netbook edition computer, and have recently updated my software because my computer asked me to and the net command recently stopped working so I assume this is the cause.
It was simply saying that the net command did not exist, but after playing around installing packages I installed samba4 and got it recognizing the command net. But it no longer works the same and does not support "rpc shutdown" nor does it appear to have any replacement for it.
Was the command simply depreciated? if so how can I stop this from happening again, I use net all the time and am not happy that it would disappear without warning.
Can I get the command back somehow, or do any of your have a replacement?

Jul 17, 2010I have two Roboards that need to communicate with one another. I have sucessfully installed Ubuntu 9.04 using the 386 kernel based on instructions found online.I can use the GUI to set up an Ad-Hoc network using one Roboard ("Create New Wireless Network"), call it Manet, and connect to "Manet" using the GUI on the other Roboard and ping/ssh between the boards. However, when I try to create the same wireless network using the command line using:
ifconfig wlan2 down
iwconfig wlan2 key off essid 'Manet' channel 5 ap any
ifconfig wlan2 up
I don't see any entry in iwconfig under "Cell". It keeps giving me "Not Associated"When I try to enter the same information on the other Roboard to try to connect to the network, it doesn't connect and under iwconfig, I don't even see any entry for ESSID. Could somebody please tell me why it works when I use the GUI and not the command line.
