Re: [ILUG-BOM] Search in a file

I then need to store the date value "24-07.2001" in a variable. Which language you are using? I assume Perl, because this is much simpler in Perl. 1. Open the file for reading. 2. Search for the above string by reading every line. $_ variable contains the current line. You can do this by using pattern searching operations in Perl. 3. Once you find the above line then split that line at spaces and collect the required date in a variable. Here is the code which I would prefer to write. open(RH,"</root/sandeep/log111.txt"); while(<RH>) { if($_ =~ /##Date/) { $flag = 1; } else { $flag = 0; } if($flag eq 1) { ($str1, $str2) = split(/ /, $_); $date = $str2; } } Hope this is very much clear.

Windows/Linux IP forwarding?
by Satya 22 Dec '01

22 Dec '01

Here's the situation: Net DSL Windowsbox LAN(dhcp) Linuxbox The LAN, naturally, has a 192.168.0.0 range of IPs (I think it's a class C). The DSL modem is connected to the Winbox on USB and the LAN is a 5-port hub supporting a windows network, with my Linux box (say hello to gort, folks) creeping in using dhcpd. The Linux box, and any box on the LAN, can access everything. I think the Net cannot access anything but the Windows box on the DSL modem (see <http://gort.cjb.net/>. That's the Winbox.). Now I need POP3 (and HTTP et al, if possible) access to the Linux box from the outside world. IP forwarding is enabled on the Winbox. What do I do now? PS: Can I get a static IP on the internal network with minimal changes to the other boxen? -- Satya. <URL:http://satya.virtualave.net/> US-bound grad students!

Re: [ILUG-BOM] mail servers

>which mail servers do you guys suggest one should use? I have heard good >things about qmail, but it requires a static ip. Exim isnt very popular and >sendmail is a tad bit scary for me... anyone else got any suggestions? I have used qmail and found out to be good. Others I haven't tried. Lot of info is available on qmail all over. Any mail server if it has to be live will need a static ip. I heard Exim is the one which can be configured as a smarthost, if you do not have static ip.

mail system queries
by abhijeet 30 Sep '01

30 Sep '01

hi i am using sendmail with fetchmail with procmail and pine......for my mail system on my linux box. 1.> Inspired by Philip's SMTP howto....i tried the following: i telnetted the port 25 on localhost......and tried to mail a message to my login....that's "abhije" now,i understand that the sendmail daemon identifies me as abhije@localhost(when i telnet the port 25)-- i get "IDENT:abhije@localhost.localdomain" as part of the response to HELO. when i say...... MAIL FROM:someone@some.other.domain ....it responds that the sender's address should resolve.....what does that mean??? i thought because it sends mail ......it should accept all sender addresses!!! At the same time.....if i say MAIL FROM:some_other_login_on_my_linuxbox@localhost the mail is sent....even if "some_other_login_on_my_linuxbox" knows nothing about it!!! my argument is that if it knows that i am abhije@localhost...and hence does not accept someone@some.other.domain....how does it accept mail from some_other_login??? i am new to sendmail..and smtp..could somebody help???? i know i could use something less scarier than sendmail.....but i need to know what's happening here...... 2.> Also is there some other mail client that has the address book facility???....i just need a break from pine..... 3.>I also have a yahoo inbox.....but the yahoo server doesn't flush the mail when polled!!!! could somebody explain that???? (yes..i have registered for pop3 access) bye abhijeet

Unable to Install Dat Drive
by Deepesh Seth 29 Sep '01

29 Sep '01

Dear All, I plugged an External HP DAT drive into redhat linux 6.2 box on Adaptec SCSI Controller. After restarting the server I used dmesg to see whether SCSI card and drive are detected .. but could not find it there. Kudzu was able to detect the Card and the hwconf shows the entries as below. class: SCSI bus: PCI detached: 0 driver: aic7xxx desc: "Adaptec|AHA-2940U2/W" vendorId: 9005 deviceId: 0010 pciType: 1 After rebooting the computer again I could not find st0 in dmesg. The SCSI Configuration utility was able to detect the DAT Drive SCSI Controller ID:7 and DAT Drv ID:8. Can somebody pls help me to configure this thing. Regards lilo

Mandrake 8.1 is out, includes XFS, ReiserFS and Ext3. Gnome 1.4.1 and KDE 2.2.1 (with antialiased fonts). Good for new users as well as experienced ones. Good for servers as well as desktops. Someone should give it a try. ISO from here: http://www.linux-mandrake.com/en/ftp.php3 Philip -- "I got everybody to pay up front...then I blew up their planet."

RE: [ILUG-BOM] transparent proxy
by shahazad＠linuxplanet.nu 28 Sep '01

Thanx for the info mahesh, well i have coupla things more to clear up, [1] do i have to enable ip_forwaring in /proc [2] what should be in the dns of the win98 client. thanx in advance cheers~ </shahazad> The iptables rule for transparent proxy is #/sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/255.255.255.0 -o eth1 -j MASQUERADE in the above rule 192.168.0.0 is the local network and 255.255.255.0 is subnet. -o eth1 option specifies the external interface which connects your proxy server/gateway to the internet.for me it is eth1.for you it might be ppp0 if you are using dialup. Enable routing on the Server. Add the IP of your proxy server as gateway in the network properties of the Windows machine.That's it. reply back if have any relative problem.
