SecNet
by Vikram Rangnekar 17 Dec '01

17 Dec '01

Hi philip, Feeling slightly disappointed that I didnt know about SecNet in time I would have loved to talk on the IPsec implementation I'm working on unlike FreeSwan I'm writing it on top of the new netfilter architecture ( > 2.4) so no recompiles of the kernel the entire IPSEC (ESP & AH) handling will be a single module and the ISAKMP daemon will be a userspace program. The only thing that really cheered me up was the Flynn Baba bashing :) I work with him on the Cyber Crime Cell as an advisor and I was pretty sick of him calling himself a network security specialist (I was suprised that he knew how to clear the IE cache ). Also I'm waiting around for my IBM linux programming contest results. Is there ANYONE ELSE ON THIS LIST who has taken part in the contest. (Known when the results r comming out ??) regards Vicky

Tiff image support in QT
by Rahul Torvi 17 Dec '01

17 Dec '01

Hi all, I am loading an image using QPixmap and successfully displaying the image in the client area of the application. But when I am working with TIF image, it is unable to load it in the QPixmap, TIFF format is not in the supported format list of QT, So when I searched, I got the following TWO options to support TIFF format in QT. First is QImageFormat's decoding procedure to install the new format. where you have to override DecoderFor, FormatName and Decode. Which I was unable to do, So any help in this case would be really appreciated. Secondly, I got the following code for defining the new format support. Which is crashing after the last line of the code. My code goes this way QImageIO::defineIOHandler( "TIF", // format name "\\x49\\x49\\x2A\\x01", // header-regexp 0, // binary format,text:"T" read_tif_image, // read-routine write_tif_image ); // write-routine QImageIO *myImageIO; myImageIO = new QImageIO( strFileName,"TIFF"/"TIF"); //tried with TIFF and TIF QIODevice *d = myImageIO->ioDevice(); QDataStream s( d ); const buflen = 24; char buf[buflen]; d->readBlock( buf, 4 ); // read signature Waiting for an early reply... Best Regards Rahul T.

You can try Astaro Firewal it includes Ipsec VPN & Pptp Vpn on Linux 2.4 Kernal. Its a German Product. For more details u can go on www.astaro.com Rgds Girish On Sat, 15 Dec 2001 Philip S Tellis wrote : > > Mr. Ambrish Kumar took the next lecture on IPSec, > touching on > implementations in windows and linux.

No.Current Linux kernel does not have built in IPSec compatibility,because of the US regulation(NSA can decrypt upto only 64-bit encryption).IPSec allows much better and easy encryption than anybody can decrypt. Some Distrubutions made outside the US like Polish distribution does provide inbuilt IPSec. I have recompiled the Linux(2.4.12) with Freeswan-IPSec(1.91) and currently using it with 2048-bit RSA encryption for my VPN network.It gives me descent(and the most secure) performance over the cable connection.

Problem with 2 NIC
by Desai Ashish 16 Dec '01

16 Dec '01

Dear Luggers, Hi...2 all..... I m facing a problem for configuring 2 NIC for sharing my Internet Connection. Plz. find the complete problembelow. I m having 2 Machines. On one I m having Direct Cable Internet Connection...i.e. on Ethernet Technology. And that machine is having Linux 7.1 with Squid configured properly. I want to share that on 2-3 machines. All other machines having Win98. I want to set up its TCP/IP Configuration as Using DHCP Server and I want to make my first PC as DHCP Server for my Internal Network. For that matter I edited the file /etc/dhcpd.conf Its contents is as follows in /etc/dhcpd.conf subnet 192.168.0.0 netmask 255.255.255.0 { range 192.168.0.2 192.168.0.10; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; option routers 192.168.0.1; } subnet 202.131.99.81 netmask 255.255.255.0 { option broadcast-address 202.131.99.255; option routers 202.131.99.81; } And then I restart DHCP Service using "dhcpd -f" command. Then it has given me error as follows. Listening on Socket /etc/192.168.0.0 Sending on Socket /etc/192.168.0.0 No subnet declaration for eth0 (202.131.99.81) Please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth0 is attched. exiting. My Internet Service Provider has provided us some fixed IPs...I would like to mentioned that I already started Squid for Netsharing. After that I've provided all the machines IP address manually. And I can be able to browse the websites. But I want to make my Linux machine as DHCP server for my Internetwork. So, in above situation where the defect amy be left by me...???? Plz. suggese me some solution for that. Regards, [Ashish Desai] __________________________________________________ Do You Yahoo!? Check out Yahoo! Shopping and Yahoo!

RE: [ILUG-BOM] mozilla problem

> /usr/X11R6/bin/mozilla: error while loading shared libraries: > > libgtk-1.2.so.0: cannot open shared object file: Input/output error > > ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > > What could the error message mean? A `shared object' file, as the name itself implies is the object file that is shareb by many programs. You have a bunch of them put up in /usr/lib. It is a DLL (dynamic linked library), which is linked at runtime. Your error suggests that GTK is not installed properly, try reinstalling it. Uninstall can be done with rpm -e <pkg name>. Then again install the GTK rpm, and yes, take care of the dependencies while install/uninstall process. Also, on a second thought, try replacing libgtk. HTH --amar -- Amarendra A. Godbole / Spare time LINUX Hacker / Microsoft ``Services For UNIX'' / These opinions are _MINE_.

Is Secnet an annual event at IITB ? Is it open for all ? (As in can an interested non-IITian engg student get in without getting bankrupt ? ;) ) Are the lectures basic, intermediate or advanced ?
