how to change apache product name on header

vi /apache_1.3.X/src/include/httpd.h

หา

#define SERVER_BASEVENDOR “Apache Group”
#define SERVER_BASEPRODUCT “Apache”
#define SERVER_BASEREVISION “1.3.X”
#define SERVER_BASEVERSION SERVER_BASEPRODUCT “/” SERVER_BASEREVISION

#define SERVER_PRODUCT SERVER_BASEPRODUCT
#define SERVER_REVISION SERVER_BASEREVISION
#define SERVER_VERSION SERVER_PRODUCT “/” SERVER_REVISION
enum server_token_type {
SrvTk_MIN, /* eg: Apache/1.3.0 */
SrvTk_OS, /* eg: Apache/1.3.0 (UNIX) */
SrvTk_FULL, /* eg: Apache/1.3.0 (UNIX) PHP/3.0 FooBar/1.2b */
SrvTk_PRODUCT_ONLY /* eg: Apache */
};

เปลี่ยนเป็น

#define SERVER_BASEVENDOR “Apache Group”
#define SERVER_BASEPRODUCT “Microsoft-IIS” << เปลี่ยนเป็นอะไรก็ได้
#define SERVER_BASEREVISION "6.0" << เปลี่ยนเป็นอะไรก็ได้
#define SERVER_BASEVERSION SERVER_BASEPRODUCT "/" SERVER_BASEREVISION

#define SERVER_PRODUCT SERVER_BASEPRODUCT
#define SERVER_REVISION SERVER_BASEREVISION
#define SERVER_VERSION SERVER_PRODUCT "/" SERVER_REVISION
enum server_token_type {
SrvTk_MIN, /* eg: Apache/1.3.0 */

SrvTk_FULL, /* eg: Apache/1.3.0 (UNIX) PHP/3.0 FooBar/1.2b */

เคยเขียนไว้เองใน thaibsd
เอามาเก็บไว้เผื่อมีคนจะใช้

two command

lofiadm -a /root/my.iso
mount -F hsfs -o ro /dev/lofi/1 /mnt/cdrom

one command

mount -F hsfs -o ro `lofiadm -a /root/my.iso` /mnt/cdrom

zpool create mypool /dev/dsk/c0t0d0
zfs list
zfs mount mypool
zfs unmount mypool
zfs create mypool/test
zfs destroy mypool/test
zfs rename mypool/test mypool/test2
zfs set canmount=off mypool
zfs set mountpoint=/home mypool
zfs set compression=on mypool
zfs set atime=off mypool
zfs set quota=1G mypool/test

bash: rsync: command not found

fix by add –rsync-path=PATH

Install JDK

emerge virtual/jdk

Config JVM
