So this is another of those documents that you will probably never have to use but..<\/p>\n\n\n\n

I came across an issue on a 100.1 system where a newly installed ALE-30h just kept getting to 4\/5 (updating) and rebooting, you could see the handset requesting the bin file but it never got a response from the system.<\/p>\n\n\n\n

After chasing my tail for too long I noticed that the handset was looking for the bin8458P & noe8458P files from the OxE, now the files on the OxE are 84x9P so the PABX had no idea what it was looking for.<\/p>\n\n\n\n

Checking on a 101.1 system I found that a symbolic link exits on that which directs requests for 8458P files to the 84x9P files.<\/p>\n\n\n\n

To begin, when a TFTP request come through from a handset the request is looked for in \/usr2\/downbin, for the IP handsets the real files mostly in usr2\/downbin\/standard\/ and as a lot of the sets share binaries to stop duplication there are symbolic links setup to allow a call for an individual file to be redirected to the \u2018real\u2019 file.<\/p>\n\n\n\n

For instance, the 8028\/8038\/8068 share the same firmware so any request ends up at the bin80x8N or noe80x8N files.<\/p>\n\n\n\n

To accomplish this a link is set to direct the request for the bin8028N file from \/usr2\/downbin\/ to \/usr2\/downbin\/standard\/<\/p>\n\n\n\n

Then a second link is put in \/usr2\/downbin\/standard to point that request to the actual file so that a request for bin8028\/8038\/8068 ends up with bin80x8N<\/p>\n\n\n\n

Eyes glazing over yet, well they will soon \ud83d\ude0a<\/p>\n\n\n\n

Now if you ever want \/need to mess with this then here is how, using my issue as the example:<\/p>\n\n\n\n

As I said the new handset was asking for the 8458P files which the system knew nothing about so I had to create the links in the system, here are the steps:<\/p>\n\n\n\n

    \n
  1. Go to \/usr2\/downbin<\/li>\n\n\n\n
  2. Elevate to root<\/li>\n\n\n\n
  3. Enter ln -s \u2018link destination\u2019 \u2018link name\u2019 so (the -s specifies symbolic rather than a hard link)
    ln -s standard \/bin8458P bin8458P
    ln -s standard\/noe8458P noe8458P
    <\/li>\n\n\n\n
  4. Then change the ownership of the links to match the rest
    chown -h root:sys bin8458P
    chown -h root:sys noe8458P
    <\/li>\n\n\n\n
  5. Now descend to \/standard
    <\/li>\n\n\n\n
  6. ln -s bin84x9P bin8458P
    ln -s noe84x9P noe84x9P
    <\/li>\n\n\n\n
  7. Repeat step 4
    <\/li>\n\n\n\n
  8. If you do an ls -al it should show if you have stuffed it up like below<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Here I had done \/standard\/noe8458P in the initial setup as well as not having yet created the file in standard\/

    So for me it was flashing red to say that the link was broken.<\/p>\n\n\n\n

    Other options<\/p>\n\n\n\n

    To remove use either
    rm \u2018link-name\u2019
    or
    unlink \u2018link-name\u2019

    To edit
    ln -sf \u2018new destination\u2019 link-name (the -sf allows you to change the destination of the link)

    <\/p>\n\n\n\n
