Problem

-- when installing B2Bi, the installation hangs for hours

-- in install.log, latest log is :

DEBUG :20220316:13.23.35:r4edi(setup):/ecd/users/ecd/ci-builder-b2bi/workspace/3_integrator-core_master_RELEASE/label/alicia/target/src/install_xib4/mb/lib/inst_mbc.s4m:463:Running command '. /u01/app/b2bi/Integrator/local/bin/core_setup;$CORE_ROOT/bin/r4edi -i -2 /u01/app/b2bi/Integrator/install/log/install.log -3 /u01/app/b2bi/Integrator/install/log/install.log /u01/app/b2bi/Integrator/install/pgm/cfgservers.x4 -I -p Integratorpool'

Resolution

1) Check if localhost is 127.0.0.1 and pingable.

2) Check if `hostname` resolves to a local IP address, and is pingable.

3) Get the domain of the machine. Make sure there is no localhost host in that domain, or another host with the same hostname.

4) check the TCP connection :

open 2 terminals :
first terminal>nc -4 -l 8832
second terminal>nc -4 -v `hostname` 8832
If connection is successful, just type text in the two terminals and check that the text is received
control-C to exit

If one of the step fails, it means that there is a DNS / host resolution issue that must be fixed before reinstalling B2Bi
