Requested address

Hi,

I get the below error that is very strange ->
" bind: Cannot assign requested address "

While running my application, i get the below error ->

bind error:
[createIPv6Socket], bind() error.
address = FEEE::219:d1ff:AAAA:705
bind: Cannot assign requested address
bind error !

Kindly let me know the possible area of problem .

Thx in advans,

It could mean that the address FEEE::219:d1ff:AAAA:705 is not assigned
to any local interface on the host.

What application is this ?

Note that FEEE::219:d1ff:AAAA:705 is in the FEC0::/10 range which was
once defined as the site-local prefix but has been deprecated and is now
reserved. Therefore you are not supposed to use it.

I use fe80::219:d1ff:fea3:705. The bind error appears for that also.
Does inet_pton(AF_INET6, s_ipv6addr, (void *)&local_addr) have any
relation with Bind failure ?
But, the strange thing is, if i hardcode the address in my code, it is
working.
Else, it is breaking with the bind error. Any ideas ?

This is a link-local address, which scope is valid only on a given link.
You may need to specify the interface in the form address%interface.

Sorry, I am not a networking programmer and cannot help you on this.

What do you mean by "hardcode" ?

'Hardcode' refers to writing something directly into the source code
of a program.
It is a kind of writing configuration parameters or port number or ip
address etc..
directly into the source code of a program.

Strange !! Interestingly, i find that the same code works between 2
computers in one setup and does not work between 2 computers
in another setup until i hardcode the ip address in the same source
code.
Any ideas ?
