[SLUG] (non) greediness in regexp ...
all, i have a ascii file which contains many lines like: first,last,occupation,someblah,[EMAIL PROTECTED] I want to replace the last email address with a bogus one. doing a reg exp replace (because of the greediness) like .*@.* will yield the entire string including the first! I want to match only the last quoted string eg .*@.* where the is the last before the @ I know how to do it in perl and awk, but I want to know how to do it using (non) greedy reg exp! thanks jobst -- Student to Teacher: Sir, what's an oxymoron?

If I could easily swap these two mount points life would be good. I've been reading up on it but I'd hate to do this without asking here first as the following just seems to easy. Is it just a matter of unmounting the filesystems and changing the mount points in fstab? Will this end up with all the files in the proper place but on swapped partitions? Unfortunately not. What you've got is: /home mountpoint using partition X /var mountpoint using partition Y Now, in partition X, you'll have directories like dazza, www, fred, etc -- that is, every single file and directory in /home is in that partition. The partition has no inherent knowledge of the fact it is being used as a /home. And over in partition Y, you'll have directories like log, run, spool, and so on -- all the stuff you see under your /var directory. If you change the /home mountpoint to use partition Y (e.g. by editing /etc/fstab), what you'll now see if you look in /home will be: /home/log, /home/run, /home/spool... which is not what you want, of course. I think you'll need to do some shuffling with a temporary partition of some sort, but I'm not really sure of the best way to do that -- hopefully someone else can offer some good suggestions on how to do that. Basically, you need to copy everything from the small partition to the big one, and vice versa. I hope I've made it clear how it works. Feel free to post again if I've confused you.

[SLUG] iptables forwarding
Hi all, Just about to take the plunge and convert all my various ipchains scripts to iptables. I like the way packets only traverse one rule, either the forward or the input rule. My question, on a firewall with PPP, a packet incoming on the PPP interface yet bound for the ethernet interface, is that counted as forward or input?

Re: [SLUG] Swapping mount points
begin Darrell Burkey quotation: I have a system that I partitioned poorly and now find that I have /home on a rather large partition and /var on a rather small partition. If I could easily swap these two mount points life would be good. I second Andrew's remarks. Go to /var and do du -Hs to find out how many bytes are stored, there. Then, do df -h to find out how much free space there is on /home (and elsewhere). If there's enough free space on /home to add a copy of /var's files alongside its existing contents, then you can probably shuffle files around without having to repartition. (Don't forget to also verify that the total size of your current /var is big enough to comfortably hold the existing contents of /home.) Assuming there's sufficient wiggle room, do this: Go to single-user mode. Do cd / ; cp -axr /var /home. Spot-check the new directory inside /home, to make sure everything seems to be there. Do rm -rf /var. Do mkdir var. Do cd / ; cp -axr /home/* /home/.??* /var Spot-check the new home directories and whatever stuff within /var. Do cd / ; umount /home /var. Edit /etc/fstab, to exchange mounting points for the two directories. Do mount -a to remount according to the revised /etc/fstab. Warning: It's morning here, and I am absolutely not a morning person.

Interesting idea! Dropping packets from a source address will mean nothing gets logged from that source IP and Apache won't see the request, but it won't necessarily stop the traffic, just filter it at your server/gateway. This is helpful if you were getting a denial of service attack that was crippling your ability to serve html to legitimate requests but isn't going to solve the problem if the attack is chewing into your bandwidth and affecting latency/data charges. Might be a cool idea to add to the script a log of the IP's being dropped that you could then email your ISP to filter out further upstream at their routers.

Interesting idea! Dropping packets from a source address will mean nothing gets logged from that source IP and Apache won't see the request, but it won't necessarily stop the traffic, just filter it at your server/gateway. This is helpful if you were getting a denial of service attack that was crippling your ability to serve html to legitimate requests but isn't going to solve the problem if the attack is chewing into your bandwidth and affecting latency/data charges. you get 1 request and quite a few incoming packets to try and establish a tcp connection. but it's not that much traffic compared to allowing the requests to happen. Anyway it's working fine for me (btw I only have one machine here anyway, but I don't want to block off the web server.) well in this solution no outgoing bandwidth is used because you don't send anything back and there is really minimal incoming traffic. I had 12 mb incoming today and 11mb yesterday because of this. I expect it to drop back to about a meg or two after this. Might be a cool idea to add to the script a log of the IP's being dropped that you could then email your ISP to filter out further upstream at their routers. Bit late at that stage you need to stop the requests in real time. by the time that happends they have finished scanning. Different if you could change the rules in real time on the other end.

[SLUG] gcc problem
Hi All, I am trying to compile some GNUstep software - MusicKit and SndKit for my debian ppc box; I'm helping out on the project where I can (mainly documentation so far). After some successful compilations of various components a gcc compiler error appears: parseScore.m:1465: Internal compiler error in `schedule_region', at haifa-sched.c: Google points me to some messages saying this has been fixed in 2.95.2, but this is Potato stable and gcc -v gives me that. Try another version of gcc he thinks. Downloads source for 2.95.3 (warned against 3.0 by one of the developers), compiles in home directory, configured ultimately for /usr/local/. Now for a very stupid question. How do I avoid interfering with my dpkg'd /usr/bin/gcc? Rename it temporarily before a make install on the new version? Is there an archive from which I could get a suitable .deb package for an earlier release of gcc even? Although some might suggest I go back to doing what I actually know about, one of the developers in particular is keen to know whether the software compiles on something other than intel machines.

Re: [SLUG] SMS trought modem
Matthieu Chauzit was once rumoured to have said: I am currently trying to see how I can implement a C program that would send a SMS throught a classic modem (without internet connection). Does anybody have some simple source code or information that would help me to implement my program ? Hey! Why bother learning to use a search engine when all these SLUG guys will do it for free? In this case, STFA (Search the friendly archives) - its been on SLUG before. I already spent a week on the net before soliciting SLUG help. Indeed I could not find a C program.

SMS transmission is not simple unless you're using something like TAP or the ASCII dialup interface that the script that was provided. Do you know which protocol your desired service uses? GSM protocol. The part which deals with that kind of application is described in: European digital cellular telecommunications system (Phase 2); Interface protocols for the connection of Short Message Service Centres (SMSCs) to Short Message Entities (SMEs) (GSM 03.39) (author: European Telecommunications Standards Institute) I'm currently working on a C implementation to handle ETS 300 916 (GSM 07.07 v5.9.1 - AT command set for GSM Mobile Equipment) and TS 100 585 (GSM 07.05 v7.0.1 - Equipment Interface for SMS and CBS) in my spare time, so I can get linux to interact with my Ericsson phone. If/when I've eventually finished this, you may find it of some use since I will have some code to handle SMS TPDUs (I already have some code to handle GSM string encoding). From what I've seen of GSM 03.39, it is outside the operational domain for most users, consquentially there is unlikely to be a free implementation of it yet. [However, if there is free implementations of this stuff, can somebody *please* point me at them :)] One of the most common methods for generating SMS traffic from land-line is by communicating with a TAP gateway - I have personally used Vodafone and Telstra's services, and I'm fairly sure that Optus also provides a similar service.

You cant get much simpler than
http://www.progsoc.uts.edu.au/lists/slug/1999/December/msg00571.html
It is about perl scripts.
Oh I see - you want someone to do the actual coding for you?
Actually its a shell-script wrapper for a chat script.
Perhaps you thought it was complex, and didnt want to reinvent the wheel.
Looking for existing code is often a good idea. But in this case you
can plainly see that it is trivial. To quote from Craig Southeren:
/usr/sbin/chat -v $DEV $DEV REPORT CONNECT ABORT BUSY ABORT 'NO
DIALTONE' ABORT 'NO CARRIER' '' ATZ OK \\dATDT${SMS_NUMBER} CONNECT ''
'QUIT)' $TARGET\\n KEY $MSG BEING SENT ATH $DEV $DEV
ie dialup, then send two lines of text: the number, and message. Its
mind-bogglingly trivial.
protocols for the connection of Short Message Service Centres (SMSCs) to
Short Message Entities (SMEs) (GSM 03.39)
Are you sure? It sounded like you wanted to use a POTS dialup SMS gateway.
I am still looking for a simple C implementation of it.
Perhaps you want to see the code for the chat program?
Why 'C'?

I shutdown all services (httpd, named, squid ...), disconnected
my LAN and the LAN based router shows no packages.
Yet I still get this when I run ngrep on the internet based
card. In case you ask the empty hash are dport 80
based requests:

RE: [SLUG] Remote X login on RH 7.1 - followup
OK, that's fixed it now, thanks, TERM=xterm .. and testing on both remote Xterminal, local console, root user and normal user is all OK now.

[SLUG] CCNA
Is CCNA worth doing these days ? I hear it's hard and expensive (?). I did a google on +ccna +sydney site:.au and turned up some broken links and seemingly dodgy sites. Is there an authoritative CCNA site ?

You want to kill a user? Thats understandable but extreem, most of us just learn to live with them. if I run it as root it works fine, as a user it complains about permissions on files and directories and users etc We need more info on what you are trying to do. Kill all processes that are running as a particular user? Cant see that you could do this without being root, unless you are themself. The print queue script will also depend on what print software you are using (and how it's been installed) BB -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
Re: [SLUG] CCNA
Expensive, maybe, but hard, i highly doubt ... CCIE theorical exams was not that difficult (ok, the lab is another story), so, if you prepare yourself correctly, you should try directly take the CCNP (my 2cent tip).

Not sure whether it is worth anything tho, typing CCNA into Seek gives a reasonable number of hits but most would expect experience to match. - Original Message - From: Minh Van Le [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, September 19, 2001 2:43 PM Subject: [SLUG] CCNA Is CCNA worth doing these days ?

There are firewall programs - not as good as a linux firewall box, but OK for personal use. Especially when you dont need any services open. Perhaps. But why the fsck would we want to discuss or recommend them on the Sydney LINUX users group mailing list? But I think the best answer was GTFOML. Amen! Can't argue with that.
