Re: How to reload SSL certificate for z/OS TN3270 server
Wayne How time flies! It seems only yesterday I was reflecting on the novelty of actually having the TN3270 server function running as an "external client" as is the relationship of all the other server - and indeed *real* client - functions associated with TCP/IP for MVS - as I first knew it - to the main address space. Actually it seems only the day before yesterday I was wrestling with this novel networking software, its peculiar ways and its cavalier approach to terminology when the same component was sometimes a "server" and sometimes a "client", whether "internal" or "external".

Re: How to reload SSL certificate for z/OS TN3270 server
Either way, Subtask of TCPIP or seperate address space, doesn't matter. To reload the SSL cert for TN3270 all secureports must be stopped. Can be done with OBEYFILE commands, but will disrupt all secure TN3270 connections. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: How to reload SSL certificate for z/OS TN3270 server
Here are my notes to install a new certificate (port 23001 is my SSL port). TO load this certificate without recycling. 1) Take the port offline: V TCPIP,tcpip,T,STOP,PORT=23001 2) Now activate it: v tcpip,tcpip,obeyfile,dsn=SYS1.TCPPARMS($$dennis) v tcpip,tcpip,obeyfile,dsn=SYS1.TCPPARMS($$dennit) for Test LPAR Where the obeyfile member has the necessary begin VTAM and TELNETPARMS section in it. If you need more detailed examples, send me a note.

How to reload SSL certificate for z/OS TN3270 server
Our SSL certificate is about to expire, and we have received a renewal certificate. Does the TN3270 server read the certificate each time a connection is established, so it will get the new one as soon as it is updated? Or is the certificate loaded into memory when the server is started, so that some action is necessary to reload it? And if it has to be reloaded, what is the least disruptive way to do it? I assume restarting the TCP/IP system would do it, but that tends to make the phones ring. -- Matt Simpson -- z/OS Support 219 McVey Hall -- (859) 257-2900 x300 University Of Kentucky, Lexington, KY 40506 http://jms.cc.uky.edu/ -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
