Re: Where to find certificate info

I was just using the IBM i FTP client to run my tests. We don't use the IBM SSL support in our products so it's not an issue for me but after Justin's questions I got curious to see what TLS levels IBM supported at the various OS. I noticed that on 7.1 the only TLS option for the QSSLPCL setting is *TLSV1 which is why I said I didn't think it was supported since QSSLPCL settings appear to be the ultimate control. I did see the options on the FTP client application in DCM but I can't get TLSV1.1 or 1.2 only to work for me. I also noticed (if you're testing out changes to the app via DCM) that if you've got a job up where you're running FTP client tests you have to sign off and on again before you see those effects in the client.

Tim,

I'm having issues with other SSL clients TLS1.2 etc, haven't looked at FTP, see my other thread.
Exactly how are you invoking FTP with SSL?

Did that already. If I have ONLY TLS1.1 and TLS1.2 selected and the server ONLY supports TLS1.1 and TLS1.2 then it doesn't work. If the server also supports TLS1.0 then it works. In fact if the server ONLY supports TLS1.0 then it works even though I have specified only 1.1 or
1.2 for the client. It looks like all the buttons are there but they're not connected to anything.

Here's what I changed for QIBM_QTMF_FTP_CLIENT:

Under SSL protocols I've got TLS1.2 and TLS 1.1 checked only.
Under cipher specs I've selected "Define" with these six in this order:
RSA_AES_128_CBC_SHA256
RSA_AES_128_CBC_SHA
RSA_AES_256_CBC_SHA256
RSA_AES_256_CBC_SHA
RSA_3DES_EDE_CBC_SHA
RSA_RC4_128_SHA

I've selected "Define" on the signature algorithm but included all 6.

The rest I left as defaults.

Tim,

In DCM, check your Application type: Client Application ID:
QIBM_QTMF_FTP_CLIENT

By default, a V7R1 system is *pgm, which is TLS1.0 SSL3.0 SSL2.0 You
probably need to change from default to TLS1.2 etc.

Also check/change the ciphers.

Did they say this was with a particular PTF? I cannot connect from my
7.1 machine to an FTP server IF the server is configured to only
accept
TLS1.2 or even TLS1.1. Only TLS1.0 will work.

I talked to IBM and 7.1 does support TLS 1.2.

I might need to correct the OS version level I gave for TLS1.2 support.
I just checked my V7.2 machine and it's there but it's not on my V7.1 box.
