There are two ways of achieving this. The first is to simply run an IRLP and EchoLink system side by side, but provide some form of signalling between the two systems so that only one can be active. The downside of this is it requires some extra hardware at the very least, another interface board and soundcard, if a Linux EchoLink program is used on the IRLP machine , and if run on two separate machines, there may be race conditions in the signalling. This allows one box to fulfil both roles and ensures that while users can decide which system to connect to, and that the node is a fully functioning node in both networks, it can't create a link between the networks.
The current version of EchoIRLP supports this mode of operation and has been extensively used in the field as of late A variation of this approach, which uses a modified EchoLinux client to connect to the EchoLink nodes, under control of the IRLP system is currently under development in the USA and is likely to be released in early The net result will be the same - a node capable of connecting to either EchoLink or IRLP, but not link the two networks together.
As of , development of the echoLinux approach seems to have stalled. This will enable the EchoIRLP scripts to seamlessly intergrate into the IRLP node, creating a unified user interface for the end user as of Feb , the system is already very transparent.
Liaison with the IRLP developers is underway to define and have provided the necessary hooks to smooth off the remaining rough edges.
The final scenario deserves a mention. Emergency communications is almost always a universal exception to the normal network rules, so the normal principle of keeping the networks separate no longer applies. However, cross links used for emergencies, training and special events should adhere to the following guidelines:. The EchoIRLP system is capable of implementing both the shared conference and dual system modes of operation. Selection of the mode of operation is done by a number of environment variables.
In addition, EchoIRLP is capable of operating in shared conference mode when connecting to known shared conferences, while using native EchoLink protocols for all other EchoLink connections, if required.
An additional option allows the node owner to choose whether to use the EchoLink directory servers or the static entries in the hosts file to resolve the IP address for the conference. Using the hosts file allows the IRLP node to connect to the conference without any association to the EchoLink network. The disadvantage is that if the IP address changes, the connection will fail.
Using the directory servers resolves this problem, but requires an EchoLink ID to be registered for the node, so it can log in. The one thing I have found is that I can connect from another Echolink Node OK and I can hear the other node OK, but when I try to transmit back, they get no audio from me, but the link stays up until disconnected.
I have tried several echo link nodes without any success. The Group moderators are responsible for maintaining their community and can address these issues. Report to Groups.

Note: Your email address is included with the abuse report. This version leaves TBD installed in default locations for easier upgrades. EchoIRLP does not provide rsync updates. This is because the repositories for the RPMs have all been removed and yum installs will. Use tbd version 1. The source directory on the source web server. Linux development subsystem. If they are not already installed,. When an. Case sensitive items will be.
I "borrowed" this section of the script from install-ra --kc6hur. You will have to remove this check to get it to install. Performs software checks for awk, sed, make, wget, and gcc. If they don't exist,. You can also order a complete kit from IRLP.
You will need to make some slight modifications to the. The modification consists of removing 1 diode, and adding. The other modification I did was to add 2 jumper wires.
Some things I encountered along the way…. So if you are going to run an irlp-reinstall, I would suggest plugging your USB key with the backup file in before you boot the PC. If you are using a GPIO interface instead of a parallel port. To enable connections to experimental nodes add.
