You didn't ask for xxxtopng, but xxxtopdf. So what counts isn't png's algorithm, but pdf's. While I didn't check pdf specifically, ps (which behaves close in these things) has a few ways to keep trivial, non- compressed bitmaps, and also has builtin the algorithms for some formats (jpeg, and I think png/gif). But most programs, convert included, do not know about this, and use only the trivial uncompressed bitmap. imgtops knows about the "advanced" features of ps and uses them. One more note: If it's for black/white (or blue/white (of a pen)) pages, the best I can recommend (takes some work, but is very good) is the following: 1. Scan in very high quality (600dpi or more, 8bit grayscale or 24bit). 2. Convert to pgm however you like (e.g. with convert). 3. Smooth with potrace. It's a very nice little program. Use '-g' to output pgm. 4. Convert to pbm with pgmtopbm -threshold -value 0.5 (or change 0.5 if it's too light or too dark). 5. Convert to g4 tiff (very efficient black/white lossless compression) with pnmtotiff -g4. 6. Collect to a single tiff with tiffcp. 7. Convert to pdf with tiff2pdf. Since pdf knows about g4, it won't take time, be very small, and hopefully (depending on source) of very high quality. I already saw there is a gui for potrace, and maybe one day I'll try to add this script to it. -- Didi = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
retrieving network interface information
Title: retrieving network interface information Hi. I have a server (kernel 2.4.20) with a network card and a cellular modem. On that server I run an application That waits for incoming connections on a known port. It is important to me to know to which Network Interface (in this case ppp0 and eth0) each incoming connection belongs to. How do I do it? I know the Solution involves the usage of ioctl() , but the documentation I found about this issue is very scarce. I would appreciate any idea (sample source code could be Even better J). Thanks.

RE: retrieving network interface information
Hello Gershon , I assume these interfaces have a different IP addresses. netstat -a shows the IP addresses on which you have opened sockets ; so it seems to me you can deduce from this to which interface each socket belongs.

socket shutdown and friends
Howdie,
Someone (i think it was Shachar) asked about shutdown and loosing messages -
well, I jsut came across the SO_LINGER socket options (man 7 socket) and
though it can help:
" SO_LINGER
Sets or gets the SO_LINGER option. The argument is a linger
structure.
struct linger {
int l_onoff;/* linger active */
int l_linger; /* how many seconds to linger for */
};
When enabled, a close(2) or shutdown(2) will not return until
all queued messages for the socket have been successfully sent
or the linger timeout has been reached. Otherwise, the call
returns immediately and the closing is done in the background.
When the socket is closed as part of exit(2), it always lingers
in the background.

Actually, what you are asking for is impossbile. Oh, the kernel knows each packet came through which interface, but this doesn't have to be the same for each packet! This is why a socket has no underlying "device", unless you specifically chose to bind it to one. Things you can do are: 1) Use the information returned by the accept() call to know the IP for the other side of the connection and decide according to that, in addition to using firewalling rules (iptables) to limit from where packets with certain source address can show up. 2) Create two sockets to listen to, one for each device and then use the SO_BINDTODEVICE socket option to make each one bound to one of the devices. From "man 7 socket": SO_BINDTODEVICE Bind this socket to a particular device like ×âÅeth0×âÂ, as speci- fied in the passed interface name. If the name is an empty string or the option length is zero, the socket device binding is removed. The passed option is a variable-length null termi- nated interface name string with the maximum size of IFNAMSIZ. If a socket is bound to an interface, only packets received from that particular interface are processed by the socket. Note that this only works for some socket types, particularly AF_INET sockets. It is not supported for packet sockets (use normal bind(8) there). Hope this helps, Gilad -- Gilad Ben-Yossef <[EMAIL PROTECTED]> Codefidence.

[OT] php3 app on php4
hi gang. I'm in an unknown territory and I'm sure one of you can help... since this is a bit off-topic you can answer me off list. I recently moved to a new server, with newer needs and thus updated software. the one thing that broke on the move from php3 to php4 was the IMP webmail client. I have installed IMP3 next to it, but some of my users must have something IMP 2.2.6 has - the ability to change their "from" address for different recipients, like I do with my domain. I hoped the only thing necessary would be to add this to my Apache's conf: AddType application/x-httpd-php .php3 and the PHP4 engine would parse the pages, but apperently it's broken... I get a blank page with no errors. has anyone got a clue? much appreciated, Ira. -- The little prince Ira Abramov http://ira.abramov.org/email/ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Is it really a blank page? try doing a "view source", my guess is that you will see the PHP code there, which means the PHP code isn't interpreted. Does it work with normal PHP files (*.php)? if yes, the AddType line is sufficient. If not - you probably forgot to load the module (using the LoadModule/AddModule directives).

I believe that a proxy cannot see what's going on inside an HTTPS session, and therefore such tool is of lesser value for me.

Hi all,
Shachar, I've missed the thread where you describe what your problem is and
I can't seem to find it in the Linux-IL archive. I'm actually quite curious
about the problem (as always about network programming).

I'll suggest the following steps (mind you there are a LOT of small details to cover though): 1. Enumerate all interfaces on your server using ioctl's interface option SIOCGIFCONF. It's not trivial to cover all aspects of all interfaces as Stevens clearly shows in his full-blown code that does this exact thing :) The code is in UNIX network programming in the ioctl chapter. I'd suggest AGAINST using it as it's exceedingly long and annoying. (much to learn from it though). Once this is done, keep the IP addresses of all your interfaces in whatever way you prefer. For IPv4 you can just save an array of in_addr types (along with names if you prefer..) 2. When a new connection is establihed, call getsockname to retrieve the IP address of the local end of the connection. 3. Look up the IP you got from step 2 in the array from ioctl(). Since the connection arrived on one of the interfaces, one must match and that is the interface you were looking for.

The product you describe might be useful while debugging the *server*, when you might have a copy of its key. It is not very useful when you're trying to debug a client (e.g., develop a script which automates the use of some site), and you don't have a key. A proxy-like solution can be used, however: the proxy can act as a terminator for both sides, checking the authenticity of the server, but presenting its own key to the client. In this case the client needs to recognize this proxy key as a valid one (for all sites), but this should be easy to do. I don't know if any available web-proxies can be easily set up to perform this sort of "man in the middle" task. -- Nadav Har'El| Tuesday, Jul 13 2004, 24 Tammuz 5764 [EMAIL PROTECTED] |- Phone +972-523-790466, ICQ 13349191 |Attention: There will be a rain dance http://nadav.harel.org.il |Friday night, weather permitting. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
