If DNS is correctly configured and working, what output do you get for your ping?
Does it say something like:-
If you see the IP address in the ping output, then you can be happy with DNS.
This could be a routing problem though. Can you publish the output from ifconfig -a and netstat -nr on your server? It may be that your ping gets to the server, but the server does not have a route to respond.
I have a multipath system with 2 physicals, a virtual and a failsafe. All network connectivity is working fine to and from all of the interfaces and the virtual. The one thing that is not working is 'ping -s'. From this machine, I cannot send and receive packets using ping -s. ping without the... (1 Reply)

I am having a problem with a new server build that has got me completely baffled. This server has a private back end network so the way it is supposed to work is that the server thinks its ip address is 10.131.0.48 but the rest of the world knows it as 199.68.100.100 per DNS. It has to be this way... (2 Replies)

I added an echo statement to make sure my variable was being read and changing. But the nslookup... (5 Replies)

iodine-client-start
IODINE-CLIENT-START(8) System Administration Utilities IODINE-CLIENT-START(8)NAME
iodine-client-start - start an iodine IPv4-over-DNS tunnel
SYNOPSIS
iodine-client-start [option]
DESCRIPTION
'iodine-client-start' starts an iodine IP-over-DNS tunnel.
-h, --help
Print help and exit
-v, --version
Print version info and exit
Invoking the program without options attempts to set up and configure an iodine IP-over-DNS tunnel using the configuration in the file
/etc/default/iodine-client or by querying the user. It tries to figure out the right way to set things up by observing the network, and if
all else fails by guessing.
QUICK CONFIGURATION
Put two lines in the file /etc/default/iodine-client
subdomain=your.tunnel.sub.domain
passwd=password_for_that_tunnel
or invoke the script with those environment variables set:
env subdomain=xxx passwd=xxx iodine-client-start
If these are not set, the script will query the user for them.
DETAILS
The configuration file consists of lines which are either comments starting with '#', or settings of the form VAR="val". Valid VARs are:
subdomain
Sample value: your.tunnel.sub.domain (no default, must be set)
passwd
Sample value: password_for_that_tunnel (no default, must be set)
testhost
Hostname to ping when testing if network is working (default: slashdot.org)
bounce_localnet
Take the local network down and then up again before starting tunnel (default: false)
test_ping_localnet
Test if the local network is working by pinging the gateway (default: true)
test_ping_tunnel
Test if the iodine tunnel is working after it has been set up by pinging the host at the other end (default: true)
test_ping_final
Test if the tunnel is working after everything is ostensibly set up by trying to ping an external host (default: true)
default_router
IP address of router on the local network---should be found automatically, set this if that fails and the program guesses wrong.
interface
Interface to use (e.g., eth1, eth0, etc) for connection to DNS server used for the iodine tunnel---should be found automatically,
set this if that fails and the program guesses wrong.
mtu
Set if tunnel MTU needs to be manually changed (lowered). Should not be necessary anymore, as recent versions of iodine negotiate an
appropriate MTU during tunnel setup. But if that negotiation does not happen, or if you are using an older version of iodine, the
default tunnel MTU is 1024, and if the local DNS server restricts to 512 byte packets you might need to use an MTU of 220.
skip_raw_udp_mode
Set "-r" option in iodine command line. With this option, iodine does not try to establish a direct UDP socket to the iodine server
on port 53. (default: true).
continue_on_error
Set if the script should continue even if a command fails. Use to test script when running as non-root. Defaults to false if run-
ning as root, true otherwise.
