A New Method for Internet Sharing between PC and MAC LAN

There is a Macintosh G3 in the office, no modem is configured, and the Internet world on the MAC has never been seen. This is one of the most regrettable things. Second, several PCs connected to the Internet have used software such as Sygate and Wingate, but due to various reasons, they have not been able to achieve the Internet sharing problem between PCs. In addition, some articles have also been written about MAC and PC can also be shared between the Internet, or by compiling the script modified PC ISDN MAC access. However, the G3 uses a USB port, and there is no switch to the MAC COM port, so there is no trial. Therefore, the newly installed ISDN has also been used by a single machine, and it has always been in the heart. Recently got WIN ME (version 4.902.525, belongs to RC1; official version is 4.90.3000), put their own win98 SE has been upgraded. Added components for "INTERNET connection sharing" when adding components. In fact, win98 SE already has, but has not been used. "INTERNET Connection Sharing" is a supporting component of the "home network" concept in WIN ME. Its purpose is to share Internet access.
After some groping, not only did the other PCs in the LAN of the office get on the Internet through the PC that originally used ISDN, and even that MAC was connected in parallel. The block in the heart finally disappeared. (Hahaha, I laughed three times)
At that time, the method was directly affixed to the "digital whiteboard" of the "Mike off class" (the well-known Chinese Apple website), and the moderator Gropius brother posted back whether he could match the picture and allowed him to go online. So he quickly wrote out EMAIL to him, but due to the rush of time, there may be problems, and it was rewritten, the ins and outs of the whole. Hope to help more friends.
First, the server settings:
Server side is installed cat or pass through the pc.
First of all, we should guarantee the installation of internet connection sharing. There is also Win se. But whether it must be, that is, whether the ordinary win98 can also use the following method, there is no test. Test friends also asked for a reply. After the installation is complete, restart, open Network Neighborhood properties, found that the "INTERNET connection sharing" protocol. And all protocols are shared by the connection. It is useful for the Internet only with the TCP/IP protocol and dial-up adapter. It can be seen that the TCP/IP protocol points to three objects: dial-up adapters, network adapters, and INTERNET connection sharing (client clients do not have this).
A. In the LAN, a fixed IP address has been set for the network card. This should be set to "192.168.0.1" and the subnet mask is still 255.255.255.0. It is common sense to open the "IP Address" card of the NIC attribute panel pointed to by TCP/IP. This is not much to say. Other card options do not need to be adjusted.
B. Open the "Internet Connection Sharing" property panel pointed to by the TCP/IP protocol, ensure that the "Automatically assign IP address" option is selected, and ensure that the "Use WINS for DHCP resolution" option in the "WINS Configuration" tab is selected.
C. Open the DNS settings of the dial-up adapter panel pointed to by the TCP/IP protocol and ensure that the "Enable DNS" option is selected.
Restart the machine. The server is configured.
Second, the PC client (client) settings:
Open Network Neighborhood properties, found that there is a big difference with the server side. The protocol for "Internet Connection Sharing" was not added, and all protocols were not shared by the connection. You can see that the TCP/IP protocol only points to two objects: dial-up adapters, network cards.
A. Open the "IP Address" card of the NIC attribute panel pointed to by TCP/IP to adjust the fixed IP address of the client network card, which can be any one of 192.168.0.2 to 192.168.0.255, and the mask is still 255.25.255.0. But the IP addresses of different machines must be different, whether pc or MAC.
Open the gateway card in the same panel and enter the server's IP address in the new gateway field: 192.168.0.1 (This also teaches you an easy way to fill in the address. Use the keypad, and enter it with the dot (.) With the mouse selected), press the "Add" button to add. Open the "DNS Settings" card in the same panel, check "Enable DNS", the host adds the client's LAN name (according to their own machine). In the DNS Server Search Order field, enter the server IP address: 192.168.0.1 and press the Add button to add it. Open the "WINS Configuration" card in the same panel and make sure that the "Disable WINS Resolution" option is not selected.
B. Open the DNS settings of the dial-up adapter panel pointed to by the TCP/IP protocol and ensure that the "Enable DNS" option is selected.
Restart the machine and you should be online.
Third, MACINTOSH client settings:
In fact, the most important way to use Internet access is to allow MACINTOSH to access the Internet. Gossip less talk. Open the TCP/IP configuration panel in the MACINTOSH control panel. The detailed setting parameters are as follows:
Connection via: Ethernet;
IP address: Any one of 192.168.0.2 to 192.168.0.254 is set arbitrarily. Be careful not to duplicate with other machines. Router address: 192.168.0.1 (It should be relative to the gateway in pc);
The name server (DNS in pc) address: 192.168.0.1.
The address of 192.168.0.1 is the IP address of the server pc. Others do not move.
Restart the machine and you should be online.
Some explanations:
1, because I am not very familiar with the mac, I do not know whether the TCP/Ip setup panel system. If not, you can download dave (networking software between the MAC and PC).
2, the client settings are basically the same. Pay attention to several points, one is the setting of the machine's fixed IP address; one is the machine's DNS settings to open, while pointing to the server's address; one wins resolution to open.
3, server address must be set to 192.168.0.1, not tested. According to the distribution of IP addresses on the Internet, it seems that this section is exclusively for internal LAN use. So try to use it.
Use win me pc friends can refer to the help instructions on the home network.
There are several findings in use:
1. The internet speed of the server side is significantly reduced; MACINTOSH is faster and more stable than other PCs. I use ISDN, MAC browsing speed reached 12.8K/sec, basically maintaining 8-9K/sec.
2. The server side can automatically respond to the Internet access application of the MACINTOSH or pc client. And often inadvertently server-side dial-up connectivity, so usually the best temporary connection to the Windows system tray sharing options to disable, so as to avoid unnecessary waste.

Glossing and calendering process in printing process

A. What is glazing?
Glossing is a colorless and transparent coating (varnish) coated (or sprayed, printed) on the surface of a print. After being leveled, dried, and calendered, it forms a thin, uniform, transparent layer of light on the surface of the print. . Coatings include full gloss, partial gloss, glossy gloss, matt (matte) gloss, and special coatings.
B. Why do you need to polish your print?
The glazing is to beautify the printed matter, protect the printed matter, strengthen the publicity of the printed matter and increase the practical value of the printed matter. The surface of the printed surface after polishing is even smoother, resulting in uniform reflection of the incident light and a brighter ink layer. Glazing is the use of varnish for surface coating of printed products. Before the final processing of the prints after printing, take appropriate measures to protect the surface of the paper or paperboard prints. After the printing, the surface is covered with a glossy film. Its application scope includes:
1 The binding of books, such as covers, covers, inserts, and calendars, calendars, advertisements, and promotional samples, etc., can increase the gloss and bright colors of printed materials through polishing.
2 Packing and decorating paper products, such as paper bags, envelopes, trademarks, etc., play a role in beautifying and protecting commodities after polishing.
3 Cultural articles, such as playing cards, postcards, and gold patterns, can resist mechanical abrasion and chemical corrosion when glazing.
4 daily necessities, foods, etc. Such as cigarettes, food, detergents and other trademarks can play a role in moisture, mold.
5 Pressing the copper foil on the hard cover can make the appearance beautiful, and its brightness is very high, very much like gold. If the combination of copper and Kiko is not strong, good adhesion properties can be obtained after polishing.
C. What are the technical requirements for coating oil?
In addition to having a colorless, odorless, strong gloss, rapid drying, and chemical resistance, the ideal coating oil must also have the following properties.
1 film transparency, no discoloration. Decorative prints to obtain excellent glazing effect depends on the formation of a colorless, transparent film on the surface of the printed sheet, and the graphic does not change color after drying. And it should not be discolored or yellowed due to sun exposure or long use.
2 film has a certain degree of wear resistance. Some glossy prints require some abrasion resistance and scratch resistance after polishing. Because of the assembly line production processes such as high-speed box-making machines, cardboard boxes and packaging machines, and book covers, the surface of prints is subject to friction and must therefore have wear resistance.
3 has a certain degree of flexibility. The glossy film formed on the surface of any type of varnish must maintain good elasticity so that it can adapt to the flexibility of paper or paperboard, and it will not be damaged or cracked or peeled off.
4 Film resistance to environmental performance is better. After glazing, some of the printed matter is used to make all kinds of packaging cartons. In order to be able to protect the products being packaged, the glazing film layer must have good environmental resistance. For example: The packaging of food, cigarettes, cosmetics, clothing and other commodities must have moisture-proof and mildew-proof properties. In addition, the chemical properties of the dried film must be stable. Do not change the performance due to contact with a weak acid or weak base or other chemical substance in the environment.
5 has a certain adhesion to the print surface. Due to the integral density value of surface ink layers, the printability of the printed matter is greatly reduced. In order to prevent the dry and cracked film from drying after use, it is required that the film has strong adhesion, and the ink and ink transfer are used in various types. Accessories have a certain degree of adhesion.
6 Good leveling and smooth film surface. There are various types of materials for printing materials, and the effects of printed graphics, such as the surface absorptivity, smoothness, and wettability, are very different. In order to make the coating on the surface of different products can form a smooth film layer, it requires coating oil. Leveling is good, film surface is smooth after film formation.
7 Printability is wide after printing. After the glazing of prints, it is generally required to go through the post-process processing, such as: molding processing, stamping and electro-aluminum processing. therefore. It is required that the post-printing processing of the coating film should be wide enough. For example, the heat resistance is better. After the electro-aluminization is stamped, no sticking phenomenon can occur; the solvent resistance is high, and the dried film cannot be blisters, wrinkles, and hair due to the influence of the adhesive in the post-processing. Viscosity phenomenon.
D. How to choose varnishes?
The choice of glazing oil must meet the basic principles of science, economy and practicality.
The so-called science refers to the need to study whether Varnish meets the physical and chemical properties of the glazing and use of printed materials. For example, the covers and seals of books, catalogs, and albums require that glazing oil not only has high transparency, but also has better abrasion resistance and folding resistance; food packaging varnish must first be non-toxic and have certain moisture-proof and anti-corrosion properties; The packaging paper carton is varnished and requires high chemical stability. It cannot be discolored or yellow due to placement (sunlight or light), or sticking and other phenomena occur due to stacking.
The economy means that when choosing a varnishes, the varnishes must be commensurate with the prints to avoid the use of high-grade varnishes for medium and low-grade prints. For example: high-end print glazing, you can choose higher cost and better quality
