I hope I helped a few people with this HOWTO, and if effects of valium did, I'd be really happy to hear from you. mstrates@croftj.net http://linloft.home.ml.org/ 1.3.

Naturally, there are p effects of valium obably better and easier ways to do things in this document. There will always be another way in the Linux World.

Connecting to the Outside World In this document, we'll explain how to do th effects of valium s using PPP (Point to Point Protocol), a popular protocol nearly always used over the Internet. It allows your modem to speak to the outside world. This is what applic effects of valium tions like Trumpet Winsock in Windows 3.x did, and many other programs that you've probably have never seen. In Linux, we use a thing called chat to do the dialing up t effects of valium the ISP and then use a utility called pppd to 'use' the connection. In a sense, chat is your dialer, and pppd is your protocol. We'll describe how to setup both below effects of valium 2.1. Talking and Communicating with pppd and chat Probably the easiest way to go about things is to make a shell script in root's home directory called ppp-connect a effects of valium d involke the script whenever you wish to make your connection. We'll discuss this method. Open up your favourite editor as root on /ppp-connect. You'll then have to effects of valium ecide on your parameters. pppd connect 'chat -v "" "your_init_string" "" ATDTisp_number CONNECT "" ogin: your_username word: your_passwd' /dev/tty(0/1/2) speed modem p effects of valium pd involkes /usr/sbin/pppd on my system, then loads up chat to do the dialing. Chat sends your_init_string to the modem, then dials isp_number. It then waits for CONNEC effects of valium , then waits for ogin: (l removed as the first character is sometimes lost), sends your_passwd, chat then terminates and hands the show over to pppd. The last of the c effects of valium mmand specifies your modem port (mine's /dev/ttyS1). In most cases it will be ttyS1 (COM2: in DOS), ttyS0 (COM1: in DOS), or if your using Slackware, cua1 or cua0. The effects of valium peed is the speed of the modem. I use 115200 for my modem (a 33.6k). If you have got a fairly recent computer (one with a 16550 UART), then I wouldn't go any lower tha effects of valium 57600. Otherwise, for 14.4k 38400. Modem just tells pppd that it's a serial/modem based connection. Remove the -v option if you don't want verbose logging to your log effects of valium iles. The scenario below is one of a person who dials up an ISP that automatically starts PPP for them, ie; they don't have a shell that actually starts. This is his c effects of valium mmand in his /ppp-connect: pppd connect 'chat "" "ATZ" "" ATDT555-1800 CONNECT "" ogin: johnny word: blackjak' /dev/ttyS1 115200 modem But for some people, they're IS effects of valium starts up a shell and doesn't automatically start PPP this may be a problem. Luckily, chat can deal with that too. You just add another command to your chat script. Fo effects of valium example, below this johnny character is using an ISP that just dumps him to a shell, requiring him to type ppp to get a ppp connection. His shell prompt ends with a $ effects of valium pppd connect 'chat "" "ATZ" "" ATDT555-1800 CONNECT "" ogin: johnny word: blackjak $ ppp' /dev/ttyS1 115200 modem If it's more than one word, ensure you quote it. I effects of valium ope you can see the drift of this, and are able to create your own script up to suit your connection. Simply modify either the first johnny or the second johnny script effects of valium to suit your taste, port, server, etc and save the file. Now you've made your file, ensure that only root can execute, read or write to it. This is extreemly important. effects of valium Also make sure nobody can read your logfiles, if you decide to leave the -v option in, as your password is seen in cleartext in the logs (I don't see much need for -v, effects of valium if you don't know what I'm talking about, leave -v out). 2.2. IP's, Domain Names and Subnets For most people using the options above, a changing IP address won't both effects of valium r them. These people include basic, easy going users, that just have dialup accounts, and aren't very technically minded. For those people, skim read this section, I'll effects of valium come to important things you need to do to setup your system properly. Newbies, skip the sections dealing with permanent IP, Domain Names, Subnets, and just read the l effects of valium st bit of this section. Getting a permanent IP address might be free for your ISP, so if in doubt ask them. Personally, I'd pay for a permanent IP address. It lets you effects of valium send e-mail to and from using a unique IP or domain, etc. If you want to get yourself a permanent IP, write an e-mail to root@yourisp.com, and ask him nicely if he can effects of valium rrange a permanent IP for you. When you get your permanent IP address, grep through your /etc directory to find where your old IP addresses are. I had to change files effects of valium in my sendmail directory and /etc/hosts. There are some other key files that you will only discover with grepping. Open up /etc/hosts, and add your new IP address in th effects of valium standard format. Reboot your computer, and you should be ready to go. You'll now need to change your chat script to reflect your new settings. If you are forced into effects of valium PPP as soon as you start your connection, you'll need to tell your System Administrator of your ISP to ensure their PPP system recognises that you have a permanent IP effects of valium ddress and allocates you that instead of a changing one. If you get dumped at a shell prompt, and you need to type ppp or something to start the connection, instead of effects of valium yping that, change your /ppp- connect script to send this instead of just ppp or whatever when it sees $ or whatever your shell prompt is. /usr/sbin/pppd :Your_IP_Add effects of valium ess Substitute your IP address for the IP address your ISP gave to you. Be sure you encapsulate the thing in " " marks when you put it into your chat script. If this d effects of valium esn't work, consult your ISP where your PPP daemon is located, and ask him for the command to give. You could just try leaving it as is and seeing if the server will re effects of valium ognise you and give you your rightful address. The next thing probably to do is to get yourself a domain name. I know that in Australia, .asn.au and .org.au are free. In the United States, you can get a .us domain for free, but they tend to be long. If your in Australia, you must go to http://www.aunic.net/ to register your domains. In the United States, it is http://www.internic.net/ . To register domains you need to be able to provide DNS services, and gorey stuff like that. If your ISP can't provide these, throw out an official .asn.au or whatever domain out the window, and get a Monolith Internet Domain. Monolith offer free domains to anybody and anyone all around the world. Everything is done without human interaction, via a web forms interface with your browser. Your domain comes in the form of Your_Choice.ml.org. Monolith will then host the DNS locally for you. If you want to send and receive mail from that domain, ask your ISP to become a mail exchanger for you. Go to http://www.ml.org/ and fill out an application, enter the NIC with your username and password, and make a
