Just got an AS400 E-series....

[gbaughma]

Here's a silly question.

I just got an AS/400 e-series (not sure of the model, but that doesn't matter for this question)

I don't have a Twinax terminal for it; and I need to change the IP address to get it on my network.

I can get into the box (using a 5250 emulator, and setting my network card on my PC to have 2 IP addresses then telnetting into it)... however, it won't let me make any changes to the IP address, since I'm connecting over ethernet.

Is there a workaround? It won't even let me change the subnet.

Thanks in advance!

That's a tricky one...

This will be risky, but you can write a CL that will end the existing TCP interfact (ENDTCPIFC) remove the TCP interface (RMVTCPIFC) & then add a new TCP interfact (ADDTCPIFC), and then start the new TCP interface (STRTCPIFC).

Of course, you need to make sure that you do not make any mistakes in this process...

I have not tried this, so I'm not even 100% sure that this will work...

Do you have a Twinax controller? If so, you may want to see if you can get a Twinax card for your PC, or try to find a used 3476 or similar terminal. If TCP is ever ended on your AS400 & TCP is NOT scheduled to restart upon IPL, without a non-TCP way to connect, you may be SOL.

Depending on what other equipment your AS/400 came with, you may have other options (such as an ASCII controller, which will allow you to connect via a modem (or perhaps even null modem cable), etc).

Good luck!

Yeah... I've got everything for twinax, *except* for a card or a terminal to plug into it.

It'd be nice to find a PCMCIA/TwinAx adapter for my laptop....

If I am not mistaken there is a converter that allows Twinax to run over IP (must be some kind of Twinax<->Ethernet converter). Try googling "Twinax to Ethernet Converters" there are a few products out there that can help.

Hope this helps.

I'll dig into it some more... but the first one I saw was a kilo-dollar.

itsp1965,

There is a converter that will allow you to use a CAT-5 (or even CAT-3) cable to connect a terminal or Twinax card to a twinax controller. I think it is called a balin.

Basically what it does is uses 2 wire (1 pair). But, unlike using Twinax, you can only hook up 1 device using this method, whereas Twinax allows up to 7.

This will not work in his circumstance, as he needs a terminal or PC Twinax card.

Greg:

I'm not really an operations guy, but you may need to sign on as QSECOFR to make that change. If that's not it, you need to configure a termianl as a console. Twinax is not the only way to do it.

Does this help? (I'm thinking you need to look at "Local Console").

(I don't know what release you are on, this is for V5R3).

Yeah... I have QSECOFR status... the problem is, it's not letting me *change* the IP or subnet of an ethernet port that I'm logged in through. <sigh>

Just had a brain thingy... try this, create a second interface on the same card with the ip and subnet you want. Make it active. Then try to connect thru the new interface. You may have to ipl, but i don't think so.

Tried it. Thought "Hey, I can assign two IP's in Windows....." but when I gave it a shot, it refused.

I'm just going to have to find someone with a terminal I can use for 5 mins.
