Operating Systems AIX Assigning Domain Server Breaks rlogin Post 302636337 by herot on Monday 7th of May 2012 09:52:19 AM

Ok. I will try to give a more detailed description of my network.

(I am aware of the public ip addressing problem. I will fix this someday soon). I inherited this network.

we have a 192.0.0.0 network. it has no gateway to the internet.
we have a 192.0.10.0 network. it has 2 gateways to the internet (one for users and one for servers to keep the bandwidth seperate).

There are a few machines on the 192.0.0.0 network (also dual-homed to 192.0.10.0) that can access the internet. They don't route packets between 192.0.10.0 and 192.0.0.0 (you can ping their 0.0 interface buy not their 10.0 interface). There aren't many machines on the 0.0 and they are all servers of some sort. The servers I am focusing on right now are 2 SCO boxes and 2 AIX boxes. None of these servers have a netcd process running.

SCOally! -->#cat /etc/resolv.conf <-ip address = 192.0.0.20
nameserver 192.0.0.20 <- server has no netsvc.conf
nameserver 192.0.0.22
hostresorder local bind
search nesdi.com


SCOissy! -->#cat /etc/resolv.conf <-ip address = 192.0.0.22
nameserver 192.0.0.2(powered off) <- server has no netsvc.conf
nameserver 192.0.0.1(no purpose now)
hostresorder local bind
search nesdi.com

AIXbddy# <-NO resolv.conf file. <-ip address = 192.0.0.60
<-ip address = 192.0.10.160
<-netsvc.conf default

AIXbackup# <-NO resolv.conf file. <-ip address = 192.0.0.55
<-ip address = 192.0.10.155
<-netsvc.conf default

all the above servers have each other specified in /etc/hosts . None of the above servers have anything setup to point to a DNS server.


Now, on the 10.0 network I only use numerical address's to talk to hosts. They all have names, but they don't resolve. I assume this is because there is no DNS server on that network. All the pc's DNS settings point to the same address as the gateway which are a linksys wrt54g (dd-wrt) for the servers and the pc's gateway/DNS point to an Untangle server. There is no domain server for the pc's. Its a 70 computer workgroup.

Let me know what I'm leaving out. Thanks again.

Socket context options - Socket context option listing

	Socket context options are available for all wrappers that work over sockets, like tcp, http and ftp.

	      o $bindto
		-  Used to specify the IP address (either IPv4 or IPv6) and/or the port number that PHP will use to access the network. The syntax
		is ip:port for IPv4 addresses, and [ip]:port for IPv6 addresses. Setting the IP or the port to 0 will let the system choose the IP
		and/or port.

	      Note

		      As FTP creates two socket connections during normal operation, the port number cannot be specified using this option.

	      o $backlog
		- Used to limit the number of outstanding connections in the socket's listen queue.

	      Note

		      This is only applicable to stream_socket_server(3).
