hostname

I use the following prompt in .zshrc: PROMPT="%{$fg[magenta]%}%n%{$reset_color%}@%{$fg[blue]%}%m %{$fg[yellow]%}%1~ %{$reset_color%}%# " When I open terminal I see this prompt: zoltan@zoltan-Macbook-Pro ~ % Is it possible to drop the text "zoltan" in the hostname? I would like to make it look like this: zoltan@Macbook-Pro ~ % Any suggestion would be greatly appreciated. Thank you! It's a bit of a mess, but you can pretend the %m is a parameter and use parameter expansion to strip the zoltan from the host name: PROMPT="...${${(%):-%m}#1} ..." A little explanation. First, you create a "parameter

I want to create a multi-tenant application that uses the hostname to determine the customer. For example: CustomerOne.myapp.com AnotherCo.myapp.com AndOneMore.myapp.com ... I can do the database and security side with no problems, I can also get the hostname from the URL, but what I am struggling to find out is how to create the basic plumbing that would allow a new customer to sign up online, provide their company name, and for the application to create the new URL, ready to be used straight away. Can anyone help? Thanks, Rob. codeulike I can't answer this exactly, but I can break it down a

We just upgraded to Java 8 on Amazon Linux. We are using Spring 4.3.8.RELEASE. It used to be that we could get our machine hostname by setting up beans in our application context file like so ... <bean id="localhostInetAddress" class="java.net.InetAddress" factory-method="getLocalHost" /> <bean id="hostname" factory-bean="localhostInetAddress" factory-method="getHostName" /> But with Java 8, the bean "hostname" now contains the string localhost Before Java 8, it used to contain the "hostname" value as run on the command line, which is [myuser@machine1 ~]$ hostname machine1.mydomain.org How can

given the ip address of a computer on the same network of my Android device, i have to find its NetBIOS/FQDN name ... is there any "clean" solution to accomplish this with the Android SDK and generally speaking in java ? Obviously InetAddress.get*HostName does not return the NetBIOS name :) Tom You can use JCIFS open source library. InetAddress addr = NbtAddress.getByName( "hostname" ).getInetAddress(); works both ways, ip address to hostname and vice versa. Actually, the code provided by Tom does not work, this code works for me (with JCIFS lib.) NbtAddress[] nbts = NbtAddress.getAllByAddress

Can anyone please explain me the difference between Host Name and Canonical Host Name? I am currently using InetAddress class to fetch host name using the IP Address. I came across these 2 APIs. So I am just wondering, which one I should opt for? There are a few difference between the two: getCanonicalHostName() will attempt to resolve the FQDN . Therefore, you would get foo.mycompany.com whereas getHostName() might just return foo . getCanonicalHostName() will always do a reverse DNS lookup, whereas getHostName() would return the stored hostname if you supplied one in the InetAddress

Is there a programatic way to find the domain name from a given hostname? given -> www.yahoo.co.jp return -> yahoo.co.jp The approach that works but is very slow is: split on "." and remove 1 group from the left, join and query an SOA record using dnspython when a valid SOA record is returned, consider that a domain Is there a cleaner/faster way to do this without using regexps? Alnitak There's no trivial definition of which "domain name" is the parent of any particular "host name". Your current method of traversing up the tree until you see an SOA record is actually the most correct.
