Anonymous FTP

Anonymous FTP

[David A. Cobb]

At least the GNU "glibc" page any your own "glibc" page, plus possibly
many
others have links < ftp://sourceware.cygnus.com/pub/glibc/ >
But, when I click, I get a username/password challenge and
"anonymous/mailname"
gets me an authorization reject.

Does your site (still) do anonymous ftp?  If so, what's the secret?

And use Netscape instead of IE.  It is a feature of IE to think you need
to authenticate yourself even if it is as simple as too many users.

Oh yeah, another bizarreness!

I have three drives/partitions: c, d, and f.  The 
mounts are correct and I can get to all of the 
drives.  c is FAT16 and d & f are NTFS.  I am 
running with ntsec.

Looky at this:

$ cd /cygdrive
$ ls
d f

Bug!?  Where is c??

Re: anonymous ftp

[Jacek Trzcinski]

Hi !

User jacek is only member of group users.
You were right as far as passwd file. For anonymous user I created in
directory /home/ftp new directory
etc where I placed passwd and group from my /etc directory. After
logging as anonymous user rights were displayed OK ( user root , group
root). Unfortunately , main problem is actual. I stll can delete as a
anonymous all files and directories from /home/ftp which after chroot is
/ for anonymous.

Here is my group file:

Is your user `jacek' member of the administrators group?

anonymous ftp does work in a chroot environment. If you don't duplicate
the /etc/passwd file to /home/ftp/etc/passwd, Cygwin can't determine
the user info correctly. I'm not quite sure why it may delete everything.
Does it have ownership and write access to it's own home dir?

> Here I show my passwd file

I'm missing /etc/group. It's not that important but it sometimes
helps to analyze the situation.

anonymous ftp

[Jacek Trzcinski]

Hi !
I have just testing setting anonymous ftp under cygwin. I have few
remarks
1) My "ftp" user has to posses the same uid as user "guest" but gid may
be any. if uid is not equal
   to "guest" uid then error "can not set uid" appeared under ftp
client. In description concerning ftp
   daemon there was example where ftp user had uid=100 and gid=10. It of
course does not work at me.
   Where is mistake ?

2) Rights problem. I utilize in my system "ntsec" switch. When I'm
logging via ftp to my cygwin ftp daemon as for example user "jacek" ,
rights to files and directories displaying by "ls -al" seem to look OK.
If locally being "root" I set owner as "root" and group as "root" to any
file or directory , ls for ftp user "jacek" displays it but... even if
only user "root" has right to write to any file and directory and "root"
is its owner , I can as a user "jacek" via ftp to delete this file or
directory !!!
If I'm logging to my ftpd daemon as a "anonymous" user then "ls -al"
shows that owner of the file is not "root" but "guest" !!! and group is
not "root" but "Administ". Without any problem I can delete
anything !!!. Where are errors ?

Here I show my passwd file

root::0:0:root for
cygwin,U-Administrator,S-1-5-21-1309239993-2107901829-782984527-500:/home/root:/bin/bash
