I'm a Linux user. I'm happy that PostgreSQL does not have win32 version. If someone wants to use a real database server, then they should install Linux (or *bsd,etc). This is what Oracle offers,too. Native Windows support will cause some problems; such as some dummy windows users will begin using it. I do not believe that PostgreSQL needs native windowz support. Ooops. I'm a Linux user too, but i have a SCO Openserver, UnixWare, Netware and lot of windows boxes in my office. Also I have Informix, Sybase ... etc. This isn't for my entertainment. Our customers need to use a real database server. But what about small business? A lot of our small customers can't spent money for dedicated linux box :((( I spent 2 month in trying open source databases (PostgreSQL, SAP DB, Interbase/Firebird) finaly i choose PostgreSQL. Now we port one of our products from Sybase SQL Anywhere to PostgreSQL. We have more than 100 customers with small networks (2-10). Most of them cant't aford dedicated linux box. Another situation DHL Bulgaria and TNT Worldwide Express Bulgaria are our customers too. In HQ they choose windows nt (i don't comment how smart is this decision), pay a lot of money to mr.Gates and now what - we say PostgreSQL is great , but .. ( and i have personal contacts with their sysadmins i don't believe they are dummy windows users) So if you don't want windows support just don't use it! ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org

Re: [HACKERS] Shrinkwrap Windows Product, any issues? Anyone? (postmaster windows shell)
I am working on getting a shrink-wrapped version of PostgreSQL for WindowsCurrently it installs a customized version of Cygwin, PostgreSQL 7.2.3, cygipc, psqlodbc, and pgadminIII currently have the setup done. Cool :) I'm now working on postmaster windows shell. It's not finished yet but main things work. Funcionality implemented now is : Console redirection for capture output from postmaster Starting-stoping postmaster Choose for shutdown mode System tray icon Postmaster options are read from registry -postmaster path -datadir -additional options Funcionality not implementedyet, but planned: Writing captured output from postmaster to log file Options setup dialog Edit pg_hba.conf ??? Application is MFC free pure windows API (compiler:gcc-mingw, Dev-C++ IDE) . Here is the screenshot I also be GLAD to read about plans for native windows port in 7.4. If anyone is interested i can post source code, or maybe this firrst steps can go to gborg as a separate project i'm not sure yet. PS: Excuse me for my english, I'm better in C :)

Re: [HACKERS] Security question : Database access control
Next your going to ask what will stop root from stopping your PostgreSQL, compiling a second copy with authentication disabled and using your data directory as it's source :) He he somebody can blow up ur home with C4, but this don't stop you from locking ur door !?! ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send unregister YourEmailAddressHere to [EMAIL PROTECTED])
[HACKERS] Security question : Database access control
Is there any way to prevent superuser to acces the database ? I mean something like "GRANT / REVOKE CONNECT" MECHANISM I have no idea how to prevent root from access data in one of this ways : root @ linux:~#su - postgres postgres @ linux:/usr/local/pgsql/bin$pg_dump or edit pg_hba.conf # Allow any user on the local system to connect to any # database under any username, but only via an IP connection: host all 127.0.0.1 255.255.255.255 trust # The same, over Unix-socket connections: local all trustor my nightmare a cygwin on Win 98 everybody can can access everything :-
Re: [HACKERS] Security question : Database access control
edit *pg_hba.conf * # Allow any user on the local system to connect to any # database under any username, but only via an IP connection: host all 127.0.0.1 255.255.255.255 trust # The same, over Unix-socket connections: local all trust what about reading pg_hba.conf comments? local all md5 Ok, but my question actually isn't about pg_hba.conf comments, i read enough but what will stop root from adding this lines or doing su - postgres ??
Re: [HACKERS] [ADMIN] Security question : Database access control
They can just read the raw database files as well. wow I'm not sure how about this edit pg_hba.conf # Allow any user on the local system to connect to any # database under any username local all trust su - posgres psql test -U dba or pg_dump test You have to be able to trust whoever has root access to the system, as well as anyone who has physical access to the system.
Re: [HACKERS] Security question : Database access control
Next your going to ask what will stop root from stopping your PostgreSQL, compiling a second copy with authentication disabled and using your data directory as it's source :) He he i'm enough paranoic :)) If you want to prevent root from accomplishing these things, you're going to have to look to your kernel for help. The kernel must prevent root from changing users, starting / stopping applications, or touching certain filesystems. PostgreSQL will let you put a password on the data. But that only works if they actually try to use PostgreSQL to get at the data. use PostgreSQL to get at the data -Yeah this will be enough i want just only REVOKE CONNECT PRIVILEGES on database
[HACKERS] COPY FROM recognize \xDD sequence - addition to copy.c idea 4 developers
1. Why i do
this:
I try to migrate a database with
a 200 tables from Sybase SQL Anywhere to PostgreSQL,
but SQL Anywhere escapes special
characters like a HEX values ( like \x0D \x2C . ).
PostgreSQL COPY FROM recognize
only OCT values ( lie \001 ... )
2. How-to it' easy :)))
2.1 - Open
$UrSourceDir/src/backend/commands/copy.c
2.2 - Add #include
ctype.h in te begining
2.3 find
function
static char
*
CopyReadAttribute(FILE *fp, bool *isnull, char *delim, int *newline, char
*null_print)
/**/
/* Add this code before it */
static int
HEXVALUE( int
c )
{
if (isdigit(c))
{
c -= '0';
}
else
{
if (islower(c))
c=
c-'a'+10;
else
c=
c-'A'+10;
}
return(c);
}
2.4 in body of CopyReadAttribute
find this
code and modify it like this
if (c == '\\')
{
c =
CopyGetChar(fp);
if (c ==
EOF)
goto
endOfFile;
switch
(c)
{
/*-- Here is my additional code --*/
case 'x':
case 'X':
{
int val;
CopyDonePeek(fp, c, true /*pick up*/); /* Get x always
*/
c = CopyPeekChar(fp); /* Get next */
if (isxdigit(c))
{
val = HEXVALUE(c);
c = CopyPeekChar(fp);
if (isxdigit(c))
{
val = (val 4)
+ HEXVALUE(c);
CopyDonePeek(fp, c,
true /*pick up*/);
}
else
{
if (c == EOF)
goto
endOfFile;
CopyDonePeek(fp, c,
false /*put back*/);
}
}
else
{
if (c == EOF)
goto
endOfFile;
CopyDonePeek(fp, c, false /*put
back*/);
}
c = val;
}
break;
/*--End of myadditional code --*/
case
'0':
case
'1':
case
'2':
case
'3':
case
'4':
case
'5':
case
'6':
case
'7':
{
int val;
val = OCTVALUE(c);
2.4 he he now make , make install
3. An idea to developers : maybe u include this
addition to COPY in future releases
10x
P.S. Excuse me for my English ( i'm better in C
:)
