...they are being used. There is a command used to create the instance and then I must edit the config files manually. If I put localhost in the secondary instance it binds. Postfix is not the problem. They are saying this is at the OS level which is why I need your help. How do I open the post for a subinterface ETH0:1 for port 25. If that isn't the solution what other troubleshooting steps should I take from the OS side as POSTFIX isn't the issue. It can't hear what it's not being allowed to listen too. -- Mike McKoy *404.590.7176* http://MyForeverHair.com http://www.MyModelTalk.com http...

Hi guys, I have multiple IPs bound to my Centos 6.6 box but I can only telnet to one IP. Any ideas on what to do? I've searched the internet so far with every keyword I can think of to no avail. I can see that postfix is only listening on the first IP and to localhost. The IP I cannot smtp to is on ETH0:1. I can access it via port 80 (web traffic) but the connection is refused if i try to

There must be something else keeping the instance of postfix from listening on that IP & port. When I set the config to localhost it only sends out using the main postfix instance and it uses the wrong IP to do so. I'm thinking something at the CENTOS level. I cannot get the port to open on 172.30.1.65 regardless of what I try. Again here is the config I have in /etc/postfix-immt/main.cf.

Hi trish, i have postfix configured to listen on that ip... it's still not listening. see below: # Note: you need to stop/start Postfix when this parameter changes. # #inet_interfaces = all #inet_interfaces = $myhostname #inet_interfaces = $myhostname, localhost inet_interfaces = 172.30.1.65 # Enable IPv4, and IPv6 if supported inet_protocols = all -- Mike McKoy *404.590.7176*

I have a router with only one physical ethernet cable. I know it''s stupid, but it is the network I have to use for a demo. I have in mind to construct an HTB class tree for some network limitations for the outgoing traffic. The question is: can i use the HTB class mechanism on 2 subinterfaces of the same physical network card without any interference? Please let me know as soon as possible. I need to know if I start working on this or I have to change the hardware. Thank you, Marius _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://ma...

Hi, I'm switching between two domains, and I need to make a couple of Linux+Samba machines provide the same shares in both domains. I've set up two sambas in the same machine, listening on different subinterfaces, but I can't make winbind to behave properly. As soon as I start the second winbind, the domain accounts provided by the first one become hidden (that is, 'getent passwd' only shows the second domain). I found both winbinds use the same UNIX socket/pipe. I found no way to choose the s...

...work as a way of preventing pier to pier communication - I only want nodes in the network to talk to the gateway (a linux box). I have successfully set up lots of sub interfaces using the vconfig too, one for each vlan. What I would like to be able to do is remove the ip address from each of these subinterfaces eth0.x and bridge them to eth0. I have successfully worked through the HOWTO, but cannot see how to adapt this to my situation. I want the network to appear to eth0 as if all the nodes are on the same network - like if I didn't use any Vlans at all. Many thanks in aniticipation ! Piccalo...

...During install, used the 'Server with GUI' group and added the virtualization packages. 3.) During install, set up team0 to include the two gig-e ports set up active-backup (two switches). 4.) During install, set up three bridges, with the slave devices being VLANs pointed to the team0 subinterfaces (using VLANs 68, 101, and 302; 101 is to be the management bridge for the host, with guests on all three VLANs).? So, for instance, bridge101 has a slave that is VLAN101 that points to team0.101 with a VLAN ID of 101.? The bridge101 interface has a manual IP address, but bridge68 and bridge30...

...g tagged traffic, but the traffic is being sent from the Cisco -I've checked it with port mirroring in the Cisco). I've performed some tests and the behaviour of VLAN in Linux seems to be as follows: when a tagged packet arrives to the interface, the kernel checks if there is some matching subinterface (for example, if the packet is tagged with VLANID=200, a eth2.200 is looked for). In that case, the packet is deliver (untagged) to that interface, otherwise the packet is discarted (so, it is never arrives to the bridge). Is that right?

Hi I have an Asterisk installation with some SIP and MGPC devices, and I also have a TE410P on a E1 line. If I make an outside ISDN data call to asterisk the phone rings as usual and if I answer it, I just hear some clicks. I've read that the D-Channel has information about the call, if its voice or data. Is it somehow possible to end/ignore this call already before it is ringing?

I know that there is a 3 network interface max for Xen 3.*. But is there a max number of network aliases? Since they are all on the same subnet then really it should just bridging the traffic. Correct? Does anyone have a PV DomU that has more than 3 IP addresses being used inside it? Thanks, Ryan _______________________________________________ Xen-users mailing list
