Sender: SuperSS SS, Area: ANSI Title: Production of special qmd 2 Modify ip Sending site: Sun and Moon Guanghua Monday, September 15, 2003 15:44:08, site mail Add a line of code in qmd that is similar to the "source" line automatically added by the system. When posting, the system will mistakenly think that it has been Added the source instead of adding the actual source To be successful, two conditions must be met First, there must be "Source: Sun and Moon Guanghua bbs.fudan.edu.cn" without quotation marks and a word in the middle. It cannot be different, including the inability to add ANSI control characters. Of course, it is okay to add it in front of "source". Do you want to add it at the beginning? It doesn't matter if the system uses " " the same way Second, the part immediately following "bbs.fudan.edu.cn" cannot be "[FROM:", otherwise it will be filtered by the system. But the way to bypass the system check is also very simple. A common method is to put FROM outside, such as "FROM:[" change Change the case, such as "[From:", change the English colon to Chinese colon, such as "[FROM ", change the form of brackets For example, "FROM:" imitates the source under Web browsing, such as "HTTP [FROM:" You can also insert ANSI control code, such as "[*[1mFROM:" This source-covering statement is valid when placed in any line of qmd. It can even be placed in the middle of a certain line. with Using this method, you can change the IP part to any text you like. Users on the Web will see the modification as well. The content after that can withstand being reprinted by others. Of course, the IP address of the reposter will be included, but your sentence remains unchanged. It cannot be used on the web. If you go to post an article, you will not be able to overwrite it successfully. In addition, if you use E to modify the article, there will be "modify" in the line below. If you have IP and add *[23;1H at the end of the qmd covering the source, if you modify it, the "modify" line will be placed Let the blue information bar cover the bottom of the screen. Of course, if it exceeds one screen, it will be invalid. The biggest disadvantage of this method is that when you enter the telnet toolbox again to modify qmd, the last sentence overwrites the source. The statement and all subsequent content will be invisible, causing a lot of trouble. This issue will be mentioned specifically later. Note that this method is currently effective in Guanghua, but it may not work at all in other BBSs. Also, the site must be I don’t support the use of this kind of qmd. It wouldn’t be difficult to ban this method, so it might become invalid one day. In fact, this is just for fun. smd has blocked ANSI controls except *[m. General users cannot really hide it.
