FTP setup

Post by Matthew Coulso » Fri, 11 Dec 1998 04:00:00

I am trying to set up my Linux box as an FTP server and HTTP server, and
since I don't know Linux security very well as I was getting it so other
people can FTP to my box I put in a definate security hole and within
two hours I no longer had su access. I am wondering exactly what I
should do to set it up so it is secure. Are there any websites with this
info? How about books? I am planning on doing a clean install of
Caldera's Open Linux 1.3 so that my errors are fixed without me having
to try to remember everything that I did that*myself over. Hope
somebody can help guide me.

1. VERY slow FTP uploads, downloads are fine --ppp or ftp setup problem?


Here is the problem: I am using ppp to connect to Internet. I've recently
discovered that when I try to upload large files ( 0.1-2MB,  mostly tar.gz
archives) via ftp it takes really long time. Trying the upload with the
hash marks on shows that uproximmately 50-100 K gets uploaded ( this is
how many
########################## appear) and then the transfer seems to stall.
Short files (1-50K) eventually get uploaded( albeit very slowly).  The
speed of FTP downloads is consistent with what I expect (2.8-3K/sec on a
28.8 modem) during the same connection, and this happens no matter what
server I try to upload a file to.

Is this likely to be an FTp or ppp problem? FTPing from WIN95 using the
same ISP  works fine both ways.

What debugging strategy would you suggest? Also-- this is something I
couldn't find from the FAQ/HOWTO/locate ppp|grep doc:
How do I find out what the negotiated connection speed has been set? (When
dialing from win, I usually get 24000 baud)

TIA for any info or suggestions. I am using the RedHat 4.1 distribution,
with no changes ( to the best of my knowledge) to relevant " factory

Best Wishes,
