Re: [ilugd] pop on public network
hi, There are many methods of achieving secure authentication already, such as APOP, KPOP, and IMAP. You can also do Secure POP via SSH. there is a mini HOWTO available on the subject. But Your mail provider may be unable or unwilling to use a more secure protocol. exactly! i have two email servers... net4india.com and vsnl.com i tried with evolution and both don't (seemingly) support IMAP/SSL/APOP/etc... only POP3 on both... this basically leaves out only the ssh tunneling option. i have managed a system based in US which is although slow, atleast can provide a ssh login! the only problem is that when i do a ssh -L 56110:pop.net4india.com:110 somebody.us.net -L56025:smtp.net4india.com:25 -C a few questions: 1. now this always asks for a password. Cant i make this automatic? i mean i give a script in /etc/rc.local (with a password) for once when the system boots, and this connection stays on? 2. is that advisable? because my system stays on for 10-12 hours, does the ssh connection die out due to no transmission?? affly rbs ___ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd

[ilugd] Client Machine's IP in PHP
Hii All ,
I Think My problem is so simple ,though i can't solve it ,
becoz i don't know how to program in PHP.
well , Problem is that , My PHP script installed in a webserver
,I just want that whenever client request for that script,Script
should return the IP address of client machine.In other word we
can say that PHP Script should return the IP address of evey
machine , where it runs.
I use getenv('REMOTE_ADDR'); function , but it returns the IP
address of server instaed of Client .
well if all of you have understand my problem then help me
Thanks in advance.

Where it runs? or IP of the person who visits your script?
$ip = getenv (REMOTE_ADDR); // get the ip number of the user
uf this dsnt work probably you have an old version of PHP

[ilugd] 7 steps to software samadhi
hi bharat, read your email with interest. especially the part on why you wish to migrate to gnuLinux. i have discovered an insightful trend over the past few years: 1) those who *react* to the problems they face in the M$ soup of OS and applications, *rush* to gnuLinux, are totally dazzled and bewildered by the completely different paradigm, and sobered, crawl back to their M$, with a 'been there, done that' attitude towards gnuLinux 2) those who *respond* to the problems they face in the claustrophobic and constrained world of M$ OS and applications, also realize M$ is really a small fraction, the visible aspect of the looming iceberg ahead, into which they crash. some aspects of the problems extend to almost all proprietory, non-freedom based software, on *any* platform. those who *respond* to the problem, always migrate successfully. so don't react, just respond. don't blame M$ or any other proprietory software company. Make your thirst for freedom, choices, of being responsible and in control of your computing, your real fuel. the desire for 'muft' and 'mukt' software should be your fuel. so how do you respond? i call it the seven steps to software samadhi by linuxlingam. step 1) get hold of a cd of gnuWin2 this cd contains freedom-based software for windoze. install openoffice, mozilla(web browser), chat software, and other stuff for windows. start using them, taking files back and forth between these and your other software, until you feel quite familiar with these software. step 2) get hold of a cd of knoppix. this is a 'live' cd of gnulinux. pop it in your cdrom, boot the machine, and presto! your pc boots into gnuLinux, forgetting the windoze in your 'c:' drive. the entire operating system and soup sits in the ram of your machine, and works off the cd. explore knoppix, reding the helpful articles provided in the browser window. explore the applications, softare, and other stuff available on the cd. you will find your openoffice, mozilla, and all other software, right there under knoppix, running under gnuLinux. so you have conquered half the battlefield already. log off from knoppix, remove the cd from the hard drive, and reboot the machine, and you are back into the world of win doze. as if nothing happened. step 3) at this point, if you feel you must migrate, buy a very good book on gnuLinux. i recommend peter norton, but you can go pick up a collection of books if you want,. this is always helpful. start reading the book, and playing with knoppix to understand the initial topics. step 4) get hold of monkeyLinux, or dragonLinux, and install them into windoze! these are special versions of gnulinux that install in the start menu of windoze, but on running them, they actually give you a complete gnulinux os! so from within windows, you can use gnuLinux. step 5) reading the book, and with help from mailing lists and friends, and tldp.org, yolinux.org, etc., learn how to partition your hard disk, and dual-boot it into windows and gnulinux. so you can use gnuLinux, and when you find you have to get back to windoze, or have to use that application not with an equivalent yet on gnulinux, use windoze. step 6) configure your gnuLinux, to network with other win based machine on the network, to access your legacy win data over partitions, etc. make sure you do all your work more and more in gnuLinux alone. step 7) my favourite one: the day you discover you don't boot into win for weeks, reformat the win partition, and free up space for more space for your data files, or install a second distribution of gnuLinux, or yet another alternative operating system, on your pc. and do go and distribute the cds of gnuWin and knoppix to your other colleagues as well. so the essence: migration is never instant. it happens in stages, and takes time, in days, weeks, or about 1 to 3 months to the outer-limit. enjoy the migration, it is a beautiful adventure in itself, and quite rewarding. it will teach you many new things. happy gnulinux software samadhi. :-) LL *** copyright 2003: LinuxLIngam. verbatim copying, distribution, and sharing of the above text is allowed in any media, so long as this notice is preserved. ___ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd

Re: [ilugd] pop on public network
Ah! You' have managed to defer snooping of the password from your local LAN to the LAN the US server is on. Don't forget, the password will still be sent in clear-text from the SSH server to the POP3 server. quite true. but that seems a slightly more acceptable idea, rather than people on the cable network here (who know that the data is easily accessible) snooping in... (i mean for that matter 99% of people on vsnl networks use pop3. and i repeat vsnl network is zillion times bigger than people on their own pop servers!! so then i guess life's not as bad as it sounds then!!! :-) but yes, i guess i need to find a better option soon!! although the password entering problem is still a bone in the neck type issue.entering a password for two such ssh logins on every boot is sounding like not a best fit solution. affly robins ___ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd
Re: [ilugd] Re: Time Lag in Linux...
OK... some background about my application We develop s/w and hardware for a small, indegeneously developed telephone exchange . The main call processing s/w runs on a i386 PC which is connected to the exchange through some properitary h/w to the main exchange. All the events are controlled and triggered through our s/w. We selected linux as OS long time back when linux was in its infancy.. This PC is not connected to external world by any means.. As this call processing s/w does all the main functinalities.. it is absolutely necessary to sync the time to real time. And also the application is expected to run for days along continusoly Now that it is clear that real-time clocking is a mission-critical business necessity, without which your actual business data would go haywire, it seems to me that someone somewhere goofed _badly_ by choosing an off-the-shelf Intel base for this project. Sorry if it sounds blunt, but that's the way I see it. At the very _least_ this project should have been on SPARC or some such better-quality hardware. All of a sudden, Ghane's SPARC suggestion does not seem like a joke at all. Now that you can't undo what has been done, I suggest that you evaluate external time clock hardware (which have Linux and NTP support) and plug some such hardware to the serial port of the PC. Such hardware is described in NTP related literature. Many options exist, including radio receivers which receive time signals from super-accurate clocks, and plain super-accurate, industrial strength external RTC hardware. And if none of that works, get a second PC, connect it to the Internet using a modem (I'd suggest a Reliance mobile phone), and run an NTP client on it. Make it connect to the Net for, say, 10 minutes every two hours, and sync its clock with NTP servers elsewhere. And get your existing telephone exchange to talk to this second PC and get its clock in sync. This is inelegant, but may be easiest to strap together with string and bandage if nothing else works.

[ilugd] upgrading kernel and installing security patches
Hi all !! I am just a beginner in Linux environment.Pleas tell me how can i upgrade my kernel and install patches that are released by redhat and others.Currently I am using RHL 9.0and please tell me does netbsd has any advantages over it as I have heard that netbsd is 'Unix-Type' and is quite secure. One more thinghow can I disable the ping and ICMP requests to my system as I am working in a LAN environment and my PC has to face a lot of scanning related to open ports and security holes. ___ ilugd mailing list [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd
Re: [ilugd] upgrading kernel and installing security patches
On Wed, 2003-08-20 at 07:04, Puneet thus hollered from the rooftop: Hi all !! I am just a beginner in Linux environment.Pleas tell me how can i upgrade my kernel and install patches that are released by redhat and others. Currently I am using RHL 9.0 If you are using RedHat and you have an available internet connection to the PC the easiest way to upgrade is to use up2date. man up2date will give you much more help on this. The relevant website is http://rhn.redhat.com I usually use up2date for upgrading everything from the RedHat site except the kernel RPM's which I prefer to download manually and install. Although up2date does a good job of upgrading the kernel RPM's also if you want it to take care of it. and please tell me does netbsd has any advantages over it as I have heard that netbsd is 'Unix-Type' and is quite secure. No flames please but IMHO OpenBSD is the more secure of the two. As to the advantages I will let someone else take up on that have not used NetBSD that much. One more thinghow can I disable the ping and ICMP requests to my system as I am working in a LAN environment and my PC has to face a lot of scanning related to open ports and security holes. Try this echo 1 /proc/sys/net/ipv4/icmp_echo_ignore_all Alternatively sysctl -w net.ipv4.icmp_echo_ignore_all=1 The above 2 methods are temporary. That is on reboot the setting will be removed. So to make this permanent either you can put any one of the above 2 lines in one of your rc files e.g /etc/rc.d/rc.local or /etc/rc.d/rc.sysinit just be careful that you put this line after the proc file system has been mounted. Or the best way is to add the following line in /etc/sysctl.conf #Stops ICMP replies from this PC. net.ipv4.icmp_echo_ignore_all = 1 To undo the above setting just substitute 0 in place of 1 in the above places. -- Arindam Dey The mind is not a vessel to be filled but a fire to be kindled.

[ilugd] SCO claims appear to be bogus
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 [Cross-posted] Evidence seems to indicate that the Linux code that SCO is claiming came from SVR4 may actually be from a much earlier, public domain version of Unix. [Quote] So...SCO's code demonstration, the one that it put up to convince its resellers of its case, comes from a version of Unix which first came out in 1979. The code was publicly circulated in the 1980's, and explicitly released under the BSD license by [the company now known as] SCO at the beginning of 2002. SCO might well have a complaint that SGI did not properly give credit for the code it used. But there is no possible way the company can argue that this code's presence in Linux is an infringement of its copyrights.
