How do I do it ? I am not able to find any option to delete
Thank you

I am writing test in nodejs.
Calling my api using requestjs.
Now I have to make one call using an ip address to the api (/resources/media)
Then I have to make another call to the same api (/resources/media) using different ip from the same computer.
OS: ubuntu
any idea how to do that
help is very much appreciated.
Thanks
Your only choice is to set up a proxy (like squid), bind it to another (virtual) networking interface card and make the second request through it.
add another ip and make sure it was not existed before
sudo ip addr add 192.168.50.5 dev eth1
Then user localAddress option in requestjs
Last several days I'm struggling with a problem.
I have two instances(ubuntu server) on gcloud and I want to assign them their external IP.
And I can ping and ssh to my instances but when I try to do telnet it is not performed.
On gcloud all instances have one internal ip and one external IP.
And they does not know their ip. I get it from gcloud console.
How could I assign it to them?
Also I've tried sudo ifconfig eth0:0 130.211.95.1 up
You can do something like this to add the external IP to a local interface:
ip addr add 130.211.95.1/32 dev eth0 label eth0:shortlabel
Replace 'add' with 'del' to remove it once you are done with it.
shortlabel can be any string up to a certain (short) length.
Update: also see this GCE support issue for related information.
A feature request for this is already filed on GCE public issue tracker, however it is not yet implemented. You can star it to get notification if any update posted on the thread.
May you also mention what's your use case? so I can probably provide you with a workaround.
I'm new to Esper and am interested in using it to send event data via a network so consequently interested in the EsperIOSocketAdapter
It appears that SocketAdapter can only bind to a specific port which is fine if there is only one network adapter but is it possible to configure the SocketAdapter to bind to a specific network adapter too by specifying its IP address?
Please create a Esper JIRA if you need this feature.
You could also use the Esper API directly and use your own Java socket transport.
I'm doing a lab for my internetworking course and I'm using GNS3 as the emulator. I can configure single FastEthernet interfaces on each router but I need to have two per router. I am using the c7200 image and router.
This is my attempt to configure the router.
Router>enable
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface f0/0
Router(config-if)#ip address 172.16.1.1 255.255.255.192
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface f0/1
^
% Invalid input detected at '^' marker.
Router(config)#
Every time I try to do the f0/1 interface I get the invalid input detected message.
WHY?!!?
Any help would be appreciated, thanks :-)
It seems the interface FastEthernet0/1 does not exist ?
Use the command Router#show ip interface brief, to verify that the interface exists.
If it doesn't exist, in GNS3 you can add additional interfaces through the configure option menu of the router(slots tab).
i had the same problem.
right click on router, click on configure, go to slots, click on slot 0, choose the second on (2FE).
apply, and ok, now u have 2 FastEthernet interfaces.
Is there a way to programmatically add hosts to the local name resolver under Linux?
I would rather avoid fiddling with /etc/hosts dynamically...
Example: add the name foo and bind it to the local port 127.1.2.3
Use Case: I have an application installed locally accessible through a web browser. I'd like the application to be accessible through a local URI.
add the name foo and bind it to the local port 127.0.0.1:9999
What is it that you want? You can add foo 127.0.0.1 to hosts or do the equivalent in your nameserver, but a connection to foo on port 1234 will always go to 127.0.0.1:1234 -- it's not possible to redirect that to port 9999 based on name, which is lost by the time connect is called.
On Linux you can add IPs to the loopback device (i.e. ip addr add 127.1.2.3 dev lo), and then use iptables to change all connections destined for 127.1.2.3:1234 to instead go to 127.0.0.1:9999, but I can't tell from your question if that the observable behavior you want.
If you'll only add hosts, a pretty safe way to do it is
echo -e "ip.add.re.ss\thostname" >> /etc/hosts
Now, if you want to remove them it starts getting hairy. I suspect you also want to remove them.
If this is the case you can use Dynamic DNS, for example, BIND has the nsupdate tool to update zone files:
$ nsupdate
> update delete oldhost.example.com A
> update add newhost.example.com 86400 A 172.16.1.1
> send
This does the following:
Any A records for oldhost.example.com
are deleted. And an A record for
newhost.example.com with IP address
172.16.1.1 is added. The newly-added record has a 1 day TTL (86400
seconds).
The google search term you want is "DDNS" for "Dynamic DNS". That's a technology for dynamically adding records to DNS servers, which sounds like exactly what you want. I'm pretty sure the bind in most lunix distros supports it, but you may need to read up on how to configure it.
I'll be going with a recent discovery: multicast-dns using the Avahi package. An example can be found here.
