I started to use CTERM again a few weeks back. Telnet might be kind obsolete in the web service age, but it did bring me back to my good old days. Sentimentally, SJTU-BBS was the last stop I had before I embraced the daily ugliness of life's nitty-gritty. Going through some old posts, I can still see a callow engineering student, nerdish and gullible, trying to do something lofty and noble with bare hands. (Lofty and Noble, I estranged myself from these two words shortly after that.) A special thanks to SJTU-BBS for lending my young self the moments that I can treasure.

*) Connect to Windows from Linux
Often times I have to get files from Windows Share (Or Linux Samba Share). Smbclient comes handy for this job:

example: smbclient //192.168.13.97/share -U hahahaha

( mount could also do the job)

*) du, df , with -h (human readable) option to get size(used, free) for disk or folder

*) inittab mtab fstab
Important tables to for init and mount.
References: Init Runlevels

*) no route to host
When "iptables" is enabled, sometimes you could get the above message. The connection is simply rejected.
Stop iptables service to avoid any over-protection: "service stop iptables"

*) useradd xxx, smbpasswd -a xxx, manage user/group

*) bookmarks for memory ordering

Linux Service:

Typical setting for my system: standalone Server for development
References(General):

To config service: /usr/sbin/ntsysv, /sbin/chkconfig
To start, stop service: /sbin/service
To check a certain service XYZ is up running or not: ps aux | grep XYZ


Service List:

==========) FreeWnn, canna
Suggested Setting: OFF
Remarks: Is that Japanese input method?
References:

==========) NetworkManager, NetworkManagerDispatcher
Suggested Setting: OFF
Remarks: For standalone server, most likely the ip is static and
configuration is straightford. Probably these two are overkill for setting
up your network.

==========) acpid, apmd
Suggested Setting: OFF
Remarks:
++) If you ever had a chance to write Windows driver, you would know first hand that life would be much easier if people are not power sensitive. So I say turn them off unless you are compulsively parsimonious or your utility bills really give you a hard time.
++) Last time I saw APM was a decade ago in the BIOS when I had an IBM Aptiva 486. It cost RMB 20,000 back then. In hindsight, that was heist in broad daylight, to put it mildly. I am glad they are bought out by Lenovo(R).
