IXI is a Eurpoean wide X.25 network, many DSAs in Europe have IXI access and all UK sites that have a JANET line can have access to IXI. This will have the advantage that you can access these European DSA without having to access the relay servce, and the European DSAs can access your data. EVERY DSA that has a Janet= address should have an IXI= address as well. The first step is to get youself an IXI address, you can do this by contacting Ian Smith (I.Smith@uk.ac.jnt). Having got one, all you need to do is tailor ISODE to use IXI! TAILORING ISODE 6.1 --------------------- If you have ISODE-6.8 the following steps are not needed - skip to the Section labelled CONFIGURING TO USE IXI. If you have ISODE-6.1 then the first step is to define IXI as a transport community so add IXI X25(80)=06+ to your isomacros file. The best way of doing this is to append the line to the support/macros.local and re-install the macros file e.g. (using csh): % cd ~isode/isode-6.[01]/support % echo "IXI X25(80)=06+" >> macros.local % su enter password after the prompt # ./make macros Then you should add the line ts_interim: IXI to your isotailor file (usually in /usr/etc/ or /usr/local/etc). CONFIGURING TO USE IXI ---------------------- The first step is to tell ISODE/QUIPU you have IXI access, to do this you need to edit the isotailor file (usually in /usr/etc/ or /usr/local/etc). Then edit the ts_communities line to look something like ts_communities: Janet IXI As a reminder, if you have PSS access you should add this to the end: ts_communities: Janet IXI Int-X25 If you have defined a LOCAL-ETHER for local communitations over the Ethernet, then you should add this before "Janet": ts_communities: LOCAL-ETHER Janet IXI The ordering of the parameters is important. If a DSA has multiple NSAP addresses, they will be tried in the order given in the ts_communities variable (from left to right). For example, the line above say "first use the local ethernet, if that fails try Janet and if that fails try IXI". NOTE: The capitalisation is important for ISODE-6.1 - copy the lines exactly as above. MODIFYING THE ADDRESS OF YOUR DSA --------------------------------- IXI addressses are expressed in a very simialar way to Janet addresses, for example the X-Tel DSA uses the IXI address IXI=20433450210398 and the Janet address Janet=00002100102998 You need to add the IXI address to the address of your DSA. The best way to do this is using dish... % dish -u "< the name of the dsa manager >" Welcome to Dish (DIrectory SHell) Enter password for "< the name of the dsa manager >": secret Dish -> modify "@c=GB@cn=< the animal name of your DSA >" An editor will be opened up, find the line beginning "presentationAddress=", this will contain the current address of your DSA (alas in the TELEX format)... presentationAddress= TELEX+00728722+X.25(80)+02+00002100102998 Append a '|' followed by the IXI address to the end on the line ... presentationAddress= TELEX+00728722+X.25(80)+02+00002100102998|IXI=20433450210398 Then exit the editor... Are you sure you want to make these changes? yes Modified 'c=GB@cn=< the name of your DSA >' Dish -> Finally restart the DSA... Dish -> dsacontrol -restart *** Problem with DSA *** Dish -> q In a few minutes time the DSA will restart, and you can start testing IXI. This simplest way to test your DSA is using the IXI address directly in a dish call... dish -c IXI=20433450210398 Welcome to Dish (DIrectory SHell) Dish -> If that happens - it should all be working. If not, try using the IXI address used above to see if you can connect to X-Tel. If that fails, contact jnt-quipu@uk.co.xtel. It sounds a lot of work - but it really is quite easy - good luck! Colin
