How can I forget children toys riffs? If your network is live, make sure that you understand the potential impact of any command. If both side do that, shutdown() actually succeeds for both of them! Because this is a blog on Cisco security, we'll talk about Cisco's product - ACS. this contact form

The read(), write(), close() and shutdown() calls, when used on a socket, may sometimes raise an ENOTCONN error.
EDIT: I am absolutely sure that the connect() call succeeded. stuck with this limit of a sum . Define the router on the ACS as an AAA Client (Network Devices) with the same shared secret. This can happen if the other end is refusing a connection, or doesn't acknowledge that it is already connected, among other things.
The runtime library never resets errno to 0. On the router, besides setting up the interface, the only other commands I entered are:R1(config)#aaa new-modelR1(config)#tacacs-server host 192.168.0.100 (IP of the TACACS+ server) key TACACSR1(config)#username backup privilege 15 secret backupR1(config)#aaa authentication Note: Each profile name must match an AAA username.Router(config)#aaa cache profile adminRouter(config-profile-map)# profile peteradmin Enter these commands in order to assign the authentication and authorization caching rules to the AAA server Re: How to revert back to TACACS+ login after connection to TACACS has been restored.

That answer is incorrect for both unix domain sockets (your case) and TCP sockets (my case). –Robert Siemer Apr 18 '13 at 3:30 add a comment| up vote 1 down vote Since New York doesn't have a residential parking permit system, can a tourist park his car in Manhattan for free?

I can never seem to reproduce it locally but there are users who can. Reset connections are so common for IPv4, that you will get them anywhere in your code, even masked as ENOTCONN in shutdown().
