If the machine have 2 IP then yes you can have same port open on the 2 separate IPs. But if you are trying to load balance so one takes over if the other goes offline then you need to use either some type of software load balancer or hardware load balancer.

The SELinux policy included with RHEL includes definitions for ports (not to mention policies and booleans) from hundreds of services, not all of which are installed of course. There is no need to remove them.

etlservicemgr is not the name of the process listening on port 9001.

We can ...

Provided you do not have a proper cable detector, or other equipment, and you do not intend to fiddle with some discovery protocols you might want to switch all the network stations, approach each station, detach the LAN cable, and attach it to a laptop or something, and see which light comes on on the switch. Two people are ideal for this. This is the ...

It is possible if your switches support discovery protocol like LLDP If your switch sends LLDP packets you can capture them on a system with tcpdump: tcpdump -s 1524 -vv -i eth0 -c 1 ether proto 0x88cc Most likely you will see port identificator on the Port ID field It may take some time to see such packet depending on switches configuration.

1. Physically Trace the cables, and mark them off as you go. 2. MAC Address If your switch infrastructure is managed and intelligent enough, you should be able to see the MAC addresses present on each port. In Cisco-land, the command is show mac-address-table on the switch. 3. CDP/LLDP Some hosts and switches may be capable of using CDP (Cisco ...

Another way of doing this is by using reverse port forwarding in ssh: On the server do: ssh -R 2222:localhost:22 _internet_server_you_own So you will end up with ssh to your machine on port 2222 on the internet_server. I think it was covered on serverfault before.

If you want to connect via SSH to a computer behind the firewall, then you will need to add a port forward (DNAT) rule to the firewall mapping port 22 (or whatever port you decide to use) to the SSH port on the internal server. TeamViewer is able to get through by using techniques such as NAT Traversal and UDP hole punching to establish a connection through ...

It sounds very much like you want to use what was some-time-ago known as 'port knocking' (thankfully it seems to have been a short-lived fashion). I believe there is google-able software for that, now that you know what you need to do. ... I would suggest though that it would be better to use something like a VPN or a client-side SSL certificate (preferably ...

What is that bind address good for? If you have multiple local IP addresses, you can choose one of them to bind the port to.

First, certificate subject (nor Subject Alternate Names extension) needs port information, because certificate identifies remote host, not specific service on remote host. Second, certificate subject must match the name/address client types in the address bar/field. It doesn't need to match internal name/address. This means that for your purposes it is ...
