Switching sendmail from Comcast to Verizon on Redhat 9

Published by Forager under science technology, web

I promised myself that if I figured this one out I will put it in blog. Took me longer than necessary: somehow Comcast did not ask for user/password authentication but verizon did–plain text unencrypted!

Configure sendmail in general:
Add to /etc/mail/sendmail.mc
————————————————-
MASQUERADE_AS(`YOURDOMAIN.COM’)dnl
FEATURE(`allmasquerade’)dnl
FEATURE(`masquerade_envelope’)dnl
————-change
define(`SMART_HOST’,`SMTP.ISP.net’)
————-check
define(`confAUTH_OPTIONS’, `A y’)dnl

Update: with RH 9 Sendmail 8.12:
need to add the following to sendmail.mc:
FEATURE(`genericstable’, `hash /etc/mail/genericstable’)dnl
GENERICS_DOMAIN_FILE(`/etc/mail/genericsdomain’)dnl
——-and change/add:
FEATURE(masquerade_envelope)dnl
FEATURE(masquerade_entire_domain)dnl

**KEY**: need to add/change genericsdomain:
localhost.localdomain ISP.net (have not tried YOURDOMAIN since I don’t need one)
localhost ISP.net

One more thing:
Edit /etc/mail/access:
AuthInfo:SMTP.ISP.net “U:USERNAME” “I:USERNAME” “P:PSWD “M:LOGIN PLAIN”

$ touch /etc/mail/masq-domains
$ touch /etc/mail/genericsdomain
$ vi /etc/mail/genericstable:
root your_reply_to@ISP.net
$ makemap -r hash genericstable.db < genericstable
$ m4 ./sendmail.mc > /etc/sendmail.cf
$ /etc/rc.d/init.d/sendmail restart

Yahoo! Contribution to China Censorship

Published by Forager under China, censorship, web

A summary article by Reuters.

Yahoo was accused of providing electronic records to Chinese authorities that led to an eight-year prison term for Li Zhi for subversion in 2003 and of helping to identify Shi Tao, who was accused of leaking state secrets abroad and jailed last year for 10 years.

Family Censor

Published by Forager under China, censorship, web

Another interesting article from NYT. Looks like Mr. French is ready to write a book about censorship in China.

Some quotes:
A classmate, Tang Guochao, agreed. “A bulletin board is like a family, and in a family, I want my room to be clean and well-lighted, without dirty or dangerous things in it.”

In the past, China’s efforts to control the Internet have often foundered in the face of the curiosity and inventiveness of Web surfers, who constantly find ingenious ways to find content that is banned and to discuss controversial topics.

(Here is the delima, even the free press in the West does not want to reveal publicly how to access this underground internet, how does it make any difference to a public that is closely monitored?)
