Week summary
Spin out/in SATA module from kernel when physically remove the drivers, especial Hot-Swap case. I did a whole testing on SNAZ-S4-400 platform(RAID0, 1,5), plug the disk out when there’s (or not) I/O, when the “miss” hard disk inserted back, the RAID were all recoveried. Bruce said, Irish had produced many disk failure issues when hotswap. I would follow up this testing and plan to use larger I/O pression.
“smbpasswd” add user to LDAP
1.In the “/etc/samba/smb.conf”, modify the second line as the following:
Passdb backend=ldapsam: ldap://192.168.123.33:389
This means the new users will be added here.
2.In localhost, # adduser phillip
# smbpasswd -a phillip
3. Then issue “ldapsearch -x”, the new user “phillip” is in the returned entries.
IE 7.0 running as IE6.0:
Microsoft supplied UASU tool for opening an IE7.0 instruce that emluates IE6 by sending the IE6 use agent string. I downloaded UASU.msc and installed, it works well on IE7.0 platform.
Perl, for about two months, I restarted to learn it now, and I must pay more attention on enhancing my program ability, such as read, write and debug. Bruce gave me a good advice, learn this program when using it, read the manul when needed. I think it is right and will be on this learning road. My schedule is spending one week, to master this program as almost our general programs are all written in Perl.
Before do anything, think about it careful, try to make it more clearly. Then, just do it.
