I have a bunch of windows machines connected to a server running samba. I would like to know if there's a way or hopefully a quick command I could type in the terminal that would tell me the machine name and the associated IP address?
View 3 RepliesI wouldn't call myself paranoid, but I do try to keep reasonably secure on my home network (WPA encryption, router firewall, etc.). I also occasionally use nmap to make sure I don't see any unknown computers logged into my network. The problem is I have five computers that all use DHCP on the network and they are not all up all of the time. At most, there are two to three online at any one time.
So, my question is: Do any of the IP addresses remain in the router's database for a computer that has gone offline (shutdown)?
The reason for my question is that today I ran nmap on my home network and noted an IP address that was not currently up on the network. It is, however, an address that is frequently assigned to one of the computers when it is online, but that address was not up at the time I ran nmap. Just trying to make sure my network is not being used by some nearby computer.
I am trying to get the MX record using dig command supplying IPv6 address of host. but i am getting connection timed out .

View 3 Replies View RelatedI came across this feature of the "less" command today. It appears not to be well-documented so I'll share it here. I found that "less" can automatically uncompress compressed files - no need to run the first command, the second does the same job:
Code:
gunzip -c textfile.gz | less
less textfile.gz
Even better, "less" can read and list the contents of some archive files as well, including Tar files compressed using Gzip and Bzip2 as well as Zip files. So now when I want to list the contents of an archive,for example to determine whether the contents will be extracted to an absolute path or relative to the working directory, the following work
Code:
less archive.tar.gz
less archive.tgz
less archive.tar.bz2
less archive.zip
Much easier than remembering the various options that the Tar, Gzip, Bzip2 and Zip use. The best one for me is with RPM archives:
Code:
less some.rpm
The above outputs the Information, Change Log and verbose File List of the RPM (paging the output, of course!) The following commands (using short and long options) give the equivalent output using the "rpm" command:
Code:
rpm -qilvp --changelog some.rpm | less
rpm --query --info --list --verbose --package --changelog some.rpm | less
"less" does not recognise the initramfs file produced by "dracut" (which is a compressed "cpio" archive), but I suppose you can't have everything ...
Is it possible to run two servers through one ip address? And I don't mean through apache to run virtual servers. Right now my set up is: Cable modem>router>server.

Fortunately this instance of Ubuntu Server is running inside a VMWare virtual machine. I can just "pause" the virtual machine if I need to rather than going through this crude and tedious start up process too frequently.
Crude and tedious are feelings I'm having too frequently lately with Ubuntu Server.
I am running Ubuntu Server 10.04 on an old desktop PC. But after some uptime (not sure exactly how long) it simply loses connectivity. Odddly, I can get on to the Server (Plug a monitor and keyboard in) and connect out (ie use lynx to go online or ping various websites) but I can't connect in from anywhere. I can't connect on the same LAN and I can't connect to it from the WAN IP address.
I have http, squid http proxy, webmin, and ssh running. I can connect to none of them when this happens. I am using ufw (I don't need the versatility of iptables... too complicated for my needs). ummm I can't think of anything else extremely pertinent....

I have wordpress installed and setup under /var/www/
The LAN IP address resolves perfectly to the index.php
However I can not get my WAN IP to resolve. My ISP blocks port 80, so I have my router setup to forward port 81 externally to port 80 of my server. I know the port forwarding is setup correctly and working, because I can go to websites like url and test that port 81 is indeed open.
I also have DynDNS setup on my router and through an account with them, to update my IP address with any changes, to a host name. But because port 80 is blocked I have to access it with, host.name.org:81. Ive had this system up and running before with no issues. Now I can not get the host.name.org:81 to resolve.
Neither can I get my ip address xx.xxx.xx.xxx:81 to resolve.

View 2 Replies View RelatedI need to Install MySql Server somewhere that I can access. Instead on installing it in a Windows box like I have for years, I'm thinking of putting it on a Ubuntu Server box (or virtual machine) instead. Should I do it on a Ubuntu Server or a Ubunto desktop box? I have never installed Ubuntu as a server, is it more or less the same as installing the desktop version? Lastly, is there multiple versions of Ubuntu where one might be more appropriate than another? All I want is a machine that I can access MySql via an IP address. Don't need DHCP, dns, Mail server or anything.

Basically I am trying to set up my own server so that I can ssh into it from anywhere. I am able to SSH into my server when I use the LAN IP of my server but I am not able to SSH into it if I use the public IP address. I have read many threads and in my opinion I've tried almost all of the common fixes suggested. One possibility may be that my ISP has blocked port 22. I have taken this into consideration and sent them an email and I'm presently waiting for a reply. However, I highly doubt that my ISP has restricted acess to port 22. I would really like to be able to SSH into my server from anywhere.
1). I installed openssh client/server using the following commands:
Code:
sudo apt-get install openssh-client
sudo apt-get install openssh-client
2). I forwarded port 22 on my router. (see attachment for the settings)
3). I modified /etc/ssh/sshd_config such that my server has a static LAN address.
contents of sshd_config file:
Code:
# Package generated configuration file
# See the sshd_config(5) manpage for details
# What ports, IPs and protocols we listen for
Port 22
# Use these options to restrict which interfaces/protocols sshd will bind to .....
I then entered the command:
Code:
sudo /etc/init.d/ssh restart
4). I turned off the firewall using the command:
Code:
sudo ufw disable
5). Here is the output of the IP tables:
Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
I have a server hosted with greatseeder.com, its a dedicated ubuntu server using Ubuntu 10.4.I have set up apache2 together with php5, and build a website from that. If you go though the ip address (http://94.23.251.209) the website loads fine, but if you go though the domain (athenagaming.com) it don't.I have registered the domain at domain.com. The nameservers I got from the host did not work, so I used a free dns site, to refer the domain to the ip address. The site I use is, http://freedns.afraid.org. I have signed up the domain, and added the nameservers i got from free dns to domain.com. But still it can't find the server though the domain, even though when I trace the domain it comes back all[URL]
