<b>Can't assign requested address</b>

Using Mac OS X 10.9 (Mavericks) I noticed that my browser wasn't working. Except
|
|
|
|
|
some sites like google. Almost nothing works anymore. Except IPV6 connections.
|
|
|
|
|
There was no problem with that. Also incomming connections on IPV4 like SSH or
|
|
|
|
|
VNC works.
|
|
|
|
|
|
|
|
|
|
So I tried to connect from the terminal:
|
|
|
|
|
|
|
|
|
|
imac:~ rogier$ telnet www.nu.nl 80
|
|
|
|
|
Trying 62.69.174.78...
|
|
|
|
|
telnet: connect to address 62.69.174.78: Can't assign requested address
|
|
|
|
|

|

|

|
|
|
telnet: Unable to connect to remote host

|
|

|
No connection possible. So what went wrong?
|
|
|
|
|
|
|
|
|
|
The netstat -a gives me really a lot of "CLOSED" connections. That could not be a
|
|
|
|
|
good sign. After some digging on the internet I came to an article on the Apple
|
|
|
|
|
discussion list about this problem. It turns out that there is (probably) a bug
|
|
|
|
|
in Mavericks. It gives you a lot of LAST_ACK connections. You can check your
|
|
|
|
|
connection state with the following command:
|
|
|
|
|
|
|
|
|
|
netstat -n | egrep '^(tcp|udp)' | awk '{print $NF}' | psort
|
|
|
|
|
|
|
|
|
|
If you do the same for IPV6, you get a whole different situation:
|
|
|
|
|
|
|
|
|
|
netstat -l
|
|
|
|
|
|
|
|
|
|
It turns out that after 20 to 25 days, something went very very wrong inside your
|
|
|
|
|
mac. The only thing that will help is rebooting the whole system. Looking at my
|
|
|
|
|
own system, I rebooted 24 day's ago.
|
|
|
|
|
|
|

|

Anyone a solution?

<b>Fixed:</b> It looks like it's being fixed in 10.9.4. Looking at the forum the cause
|
|
|
|
|
of the problem isn't found, but it's solved by upgrading to 10.9.4.
