buy valium online Compressed TCP/IP-Sessions using SSH-like tools Sebastian Schreiber 2.2.2000 1. Introduction In the past, we used to compr buy valium online ss files in order to save disk space. Today, disk space is cheap - but buy valium online andwidth is limited. By compressing data streams, you achieve two goals buy valium online 1) You save bandwidth/transfered volume (that is important if you have buy valium online to pay for traffic or if your network is loaded.). 2) Speeding up low- buy valium online andwidth connections (Modem, GSM, ISDN). This HowTo explains how to sav buy valium online both bandwith and connection time by using tools like SSH1, SSH2, Open buy valium online SH or LSH. 2. Compressing HTTP/FTP,... My office is connected with a buy valium online 4KBit ISDN line to the internet, so the maximum transfer rate is about buy valium online K/s. You can speed up the connection by compressing it: when I download buy valium online files, Netscape shows up a transfer rate of up to 40K/s (Logfiles are c buy valium online mpressable by factor 15). SSH is a tool that is mainly designed to buil buy valium online up secure connections over unsecured networks. Further more, SSH is ab buy valium online e to compress connections and to do port forwarding (like rinetd or red buy valium online r). So it is the appropriate tool to compress any simple TCP/IP connec buy valium online ion. "Simple" means, that only one TCP-connection is opened. An FTP-con buy valium online ections or the connection between M$-Outlook and MS-Exchange are not si buy valium online ple as several connections are established. SSH uses the LempleZiv (LZ7 buy valium online ) compression algorithm - so you will achieve the same high compression buy valium online rate as winzip/pkzip. In order to compress all HTTP-connections from m buy valium online intranet to the internet, I just have to execute one command on my dia buy valium online -in machine: ssh -l -C -L8080::80 - buy valium online sleep 10000 = host that is located at my ISP. SSH-access i buy valium online required. = my login-ID on =the buy valium online eb proxy of my ISP My browser is configured to use localhost:8080 as pr buy valium online xy. My laptop connects to the same socket. The connection is compressed buy valium online and forwarded to the real proxy by SSH. The infrastructure looks like: buy valium online 64KBit ISDN My PC--------------------------------A PC buy valium online (Unix/Linux/Win-NT) at my ISP SSH-Client compressed SSH- buy valium online erver, Port 22 Port 8080 | | buy valium online | | | | buy valium online | |10MBit Ethernet buy valium online 100MBit |not compressed |not compressed | buy valium online | | | buy valium online My second PC ISP's WWW-proxy with Netscape,... buy valium online Port 80 (Laptop) 3. Compressing Email 3.1. Incomi buy valium online g Emails (POP3, IMAP4) Most people fetch their email from the mailserve buy valium online via POP3. POP3 is a protocol with many disadvantages: 1. POP3 transfe buy valium online s password in clear text. (There are SSL- implementations of POP/IMA buy valium online and a challenge/response authentication, defined in RFC-2095/2195). buy valium online 2. POP3 causes much protocol overhead: first the client requests a buy valium online essage than the server sends the message. After that the client requ buy valium online sts the transferred article to be deleted. The server confirms the d buy valium online letion. After that the server is ready for the next transaction. So buy valium online transactions are needed for each email. 3. POP3 transfers the mails wi buy valium online hout compression although email is highly compressible (factor=3.5). buy valium online You could compress POP3 by forwarding localhost:110 through a compress buy valium online d connection to your ISP's POP3-socket. After that you have to tell you buy valium online mail client to connect to localhost:110 in order to download mail. That secures and speeds up the connection -- but the download time still suffers from the POP3-inherent protocol overhead. It makes sense to substitute POP3 by a more efficient protocol. The idea is to download the entire mailbox at once without generating protocol overhead. Furthermore it makes sense to compress the connections. The appropriate tool which offers both features is SCP. You can download your mail-file like this: scp -C -l loginId:/var/spool/mail/loginid /tmp/newmail But there is a problem: what happens if a new email arrives at the server during the download of your mailbox? The new mail would be lost. Therefore it makes more sense to use the following commands: ssh -l loginid mailserver -f mv /var/spool/mail/loginid /tmp/loginid_fetchme scp -C -l loginid:/tmp/my_new_mail /tmp/loginid_fetchme A move (mv) is a elementary operation, so you won't get into truble if you receive new mail during th
