A. Background
The CERT Advisory CA-2002-17 regarding Apache affects the
following HP products:
B9415AA Apache 1.3.x PA-RISC HP-UX releases 11.00 and 11.11
B9416AA Apache 2.x PA-RISC HP-UX releases 11.00 and 11.11
B9415AA Apache 1.3.x IPF HP-UX releases 11.20 and 11.22
B9416AA Apache 2.x IPF HP-UX releases 11.20 and 11.22
B9416BA Apache 2.x IPv6 PA_RISC HP-UX release 11.11
OpenView NNM 6.01, 6.1, 6.2, 6.31 running on HPUX or SOLARIS
OpenView SIP 1.0, 2.0, 3.0 running on HPUX or SOLARIS
HP Apache 1.3.26 (PA-RISC)
installs into /opt/apache and /opt/tomcat
disk space: 55-65 MB
documents: /opt/apache/htdocs/doc
HP Apache 2.0.39 (PA-RISC)
installs into /opt/hpapache2
disk space: 80-90 MB
documents: /opt/hpapache2/hp_apache_docs
HP Apache 1.3.26 (IPF)
installs into /opt/apache and /opt/tomcat
disk space: 65-75 MB
documents: /opt/apache/hp_apache_docs
HP Apache 2.0.39 (IPF)
installs into /opt/hpapache2
disk space: 80-90 MB
documents: /opt/hpapache2/hp_apache_docs
HP Apache 2.0.39 IP version 6 (PA-RISC)
installs into /opt/hpapache2
disk space: 80-90 MB
documents: /opt/hpapache2/hp_apache_docs
Before updating, make sure to stop your previous HP Apache
binary. Otherwise, the previous binary will continue running,
preventing the new one from automatically starting, although
the installation would have been successful.
The command to stop the HP Apache binary is:
For 1.3.26:
/opt/apache/bin/apachectl stop
For 2.0.39:
/opt/hpapache2/bin/apachectl stop
HP Apache automatically starts upon installation if port 80
is available.
Installation of this new version of HP Apache over an existing
HP Apache installation is supported, while installation over a
non-HP Apache is NOT supported.
