An inbound UDP from 129.33.82.52

This morning, my Symantec client firewall popped up this warning:

A remote system is attempting to access Microsoft Generic Host Porcess for Win32 Services on your computer.   

Program:                    svchost.exe

Path:                            C:\WINDOWS\system32\

Protocol:                    UDP (Inbound)

Remote Address:        129.33.82.52 : 1421

Symantec recommended to permit always.  Just to be safe, I clicked Block Once.  Then there came another UDP from a different host/port in the same subnet: 129.33.82.51 : 1211.  After clicking Block Once again, another UDP from 129.33.82.50 : 1211. 

Whois search (http://cqcounter.com/whois/) result for these hosts:

IP Address   : 129.33.82.52 [ testws001.boulder.mebs.ihost.com ]
ISP : IBM
Organization : IBM
Location : US US, United States
City : Durham, NC 27709
Latitude : 35°91'38" North
Longitude : 78°84'89" West

Last evening, I was trying to download Thinkpad upgrades from ibm website in another machine.  That might have been the cause for these UDP requests.  After blocking them, I haven't seen any side-effects yet.  So I think it's safe to do so.

绕口令:吃葡萄不吐葡萄皮,不吃葡萄倒吐葡萄皮



记不清接下来是什么了。以前总认为这只是个绕口令,纯粹文字游戏而已。前半句--吃葡萄不吐葡萄皮--还可以解释,那是因为考虑到葡萄皮的营养连皮吃。可是不吃葡萄哪里来的皮可吐呢?

后来有一次我给丁剥葡萄吃,用手剥,也用牙齿剥。用牙齿剥了就把皮吐出来。我只是剥皮吐皮,没有吃葡萄,丁吃剥了皮的葡萄,不用吐皮。我一下子意识到这就是绕口令里的情形。

不知道谁想出了这个绕口令,我猜想他或她肯定是在给孩子剥葡萄皮的时候产生了灵感。

这短短两句话居然要用二三十年的时间来体会。不知道我小的时候有没有吃葡萄不吐葡萄皮?
