Peter, Thanks for the suggestions. Ping behaves the same whether I telnet into a line-mode TSO session, log on through normal tn3270, or run oping from an OMVS shell.
BTW, I had the network guy remove the changes he made to the F% load balancers and it made no difference. Rex >Did anyone change IKJTSOxx or issue the PARMLIB command or >SET IKJTSO=xx command? Is PING defined to AUTHCMD? Does ping behave the same from a shell session? Log-in through telnet and try "oping some.host.name" Peter Hunkeler CREDIT SUISSE ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
