-ChanServ- [#trilug-rhce] Welcome to the TriLUG RHCE Study Group Channel <RedWolfe> hello folks? <Sinner_> howdy <Sinner_> right here, right now <Sinner_> :) <Sinner_> hi there <Sinner_> ping jeremyp ? <Sinner_> ping jimstigator ? <Sinner_> ping tanner ? <jtower> ping yahoo.com ? <jaimie> Jaimie's Here <jaimie> ping pong <Sinner_> howdie jaimie, thank you for the offer of hth <sweeper> yahoo.com not found <jtower> jaimie? that takes me twice as long to type as jon <Sinner_> http://comic.escomposlinux.org * sweeper will only be reading and chiming in occassionally <Sinner_> jtower: use tab completion <jaimie> Not a prob, Sinner <Sinner_> sweeper: that's fine with me <jtower> Sinner_: assume everything i say is laced with sarcasm <Sinner_> jtower: that's right. you've lived in the IK AND you like RedDwarf <jtower> too bad about rock, eh? <jeremyp> Evening folks. <Sinner_> it's been a real bummer the Rock thing <Sinner_> jtower: it's awful <Sinner_> g'night jeremyp <jtower> he who lives by the rock, dies by the rock <RedWolfe> Rock on. <Sinner_> Keep on Rockin! <jaimie> so what happened to Rock biz? <JonC> Someone bigger thought his location and biz model was good <JonC> They moved in down the street <Sinner_> and some thugs started breakin in and getting "free PCs" <JonC> CompUSA <RedWolfe> I heard it was CompUSA <jaimie> That's gotta hurt... <jtower> thank god they didn't take rimmer! <Sinner_> it's very sad <jeremyp> Did he not have insurance for the break-ins ? <jtower> i'm gonna throw rocks at compusa to show support for him <Sinner_> I believe that yes, he had insurance <jtower> and because it just feels right <JonC> The topic tonight...? <jeremyp> what things to people need to learn about configuration ? <jimstigator> hi all <jeremyp> s/to/do ? <jeremyp> jimstigator! <jtower> how about how to configure freeswan with multiple interfaces? <jeremyp> er... <jtower> j/k <jeremyp> Somehow I think that's a bit beyond lokkit :) <Sinner_> i believe that this is out of rhce scope <jimstigator> Oracle 9i on 64mb of ram <jeremyp> a/k/a redhat-config-firewall (?) <Sinner_> (freeswan) <jaimie> I have a question about rpm <jeremyp> err it's actually redhat-config-securitylevel <jtower> jimstigator: i hear that 640k ought to be enough for anybody <Sinner_> jaimie: shoot <JonC> Freeswan works out of the box on multiple interfaces <jaimie> will rpm -Fuv mess with in place config files, or do I need to backup, upgrade, and restore the configs from backup. Specifically, this is about Sendmail. <JonC> You configure each SPA to leave one defined interface and enter another <JonC> You configure a set of SPA's for every interface you want to connect via a tunnel <Sinner_> jaimie: it will leave your current config files in place <jeremyp> jaimie: it won't mess with your configs. If properly pacakged, the config file will be extracted as /etc/mail/sendmail.cf.rpmnew <Sinner_> jaimie: and you will get the new ones installed with the name "foo.cfg.rpmnew" <jaimie> xcellent. <RedWolfe> jaimie: when I upgraded Sendmail, it put the new stuff in place with a .rpmnew suffix <Sinner_> jaimie: welcome to "this makes sense" world of Linux and OpenSource <jeremyp> Some RPMs will replace the configs, but save the old ones as ".rpmsave" -- but Red Hat RPMs don't generally do that (it's frowned upon nowadays) <RedWolfe> you will have to edit the .rpmnews to get full functionality. <Sinner_> this will happen if the new RPM is a version that uses a completely different config file <Sinner_> as with the old config it wouldn't work <jeremyp> Right, sometimes the new program can't be backward compatible so you have to migrate changes manually <Sinner_> but you never loose the config file. it's a beauty <jeremyp> I think that might have happenned to BIND named at one point, for example <Sinner_> and to Apache, like upgrading from RH 6.2 to RH 7.3 <jeremyp> Though if you do multiple upgrades in a row, without backing up, you could lose the config file <jaimie> i assumed as much, but the less I have to do the better. <jeremyp> Because RPM will clobber that .rpmsave file on the second upgrade <jaimie> Leaves more time to kick scream and curse the Winblows servers. <Sinner_> exactly <Sinner_> you got it right <Sinner_> BTW <Sinner_> are you all patched against sendmail vulnerability? * jeremyp was patched within about 5 minutes of the errata release .. *grin* <jtower> Sinner_: yup. rpm -e sendmail && rpm -i postfix <jeremyp> (well, about 5 minutes after I found out about it) <Sinner_> ;) <Sinner_> I started with postfix so no changes here *grin* <RedWolfe> they haven't issued a patch for 8.0.94 (8.1) <jeremyp> RedWolfe: you can use the one for RHL 8.0 <jeremyp> Notice that sendmail was upgraded for the RHL 8.0 errata, so no different than what was "shipped" in 8.0.94 except for the security update <jtower> here's one: i tried installing phoebe on my mini-itx board but the kernel crashes immediately. can i use a rh8 boot disk to install rh8.1 beta? <jtower> rh8 goes on without a hitch <Sinner_> jtower: the boodisk? <Sinner_> jtower: it will bomb out <Sinner_> jtower: enter a bug <Sinner_> or check the md5sum <jtower> i used the boot.iso image burned to a cd <Sinner_> of your phoebe <jtower> md5's are good <Sinner_> and setup.exe are evil * sweeper gets caught up on the current chatter <jeremyp> jtower: does that boot.iso work on another PC ? <jtower> that little boot.iso image rocks, sure beats having to make floppies to do nfs installs <jaimie> How easy is it to go from Sendmail to Postfix, really. Is it a no-brainer drop in that I can do in 10 min at midnight, or will it require more dedicated effort? <sweeper> did we decide on-list whether or not we're meeting next week? <jtower> jeremyp: haven't tried it elsewhere <jeremyp> jtower: have you tried a floppy boot disk with that same PC ? <jeremyp> sweeper: no <jtower> mini-itc has no floppy connector, ide only <sweeper> jeremyp: do we want to? :) <Sinner_> jaimie: postfix is a "sendmail-compatible" MTA <Sinner_> jaimie: how tweaked is your sendmail config? <jaimie> Sinner_: Not very, but we do host some virtual domains for various non-profits using sendmail and bind. <Sinner_> sweeper: we haven't decided yet, nope <jeremyp> jaimie: if you have a complicated mail setup, it could take some non-trivial amount of work <Sinner_> jaimie: postfix is waaaaay simpler that sendmail to configure <JonC> The installs that I've transisitioned over worked fine (including the virtuserfile) <Sinner_> jaimie: you can confortably use webmnin to adminiser posftix <jeremyp> Oh, I didn't realize it was backward compatible with virtuserfile and stuff, cool <JonC> Well the complication in this setup is only to make Sendmail well tuned for the system its on <JonC> Postfix should do as good a job as I did in tuning (and better) <jeremyp> sweeper: Dunno. It's fine with me, I think <RedWolfe> but sendmail is *historical*! <JonC> Postfix is optimized so that it doesn't let slow MTA sites bogg it down - it moves those mails to the end of the queue <jaimie> Not too worried about tuning. The box is _way_ overkill for the job of routing mail. <JonC> In that case, have fun! <jtower> speaking of email, is it possible to make the default IMAP daemon read a user's inbox that is not in /var/spool/mail? <JonC> I think you can set an env variable <jaimie> Speaking of env vars. Where is the default lang var set for all users? <jtower> i prefer to send all mail ~/mail but i can't figure out how to get IMAP to read it (without compiling from scratch) <jeremyp> jtower: well you can just have procmail deliver it there <JonC> in /etc/profiles <jeremyp> jaimie: /etc/syconfig/i18n <jeremyp> /etc/sysconfig that is <jtower> jeremyp: so can postfix. the problem is with IMAP, it insists that the inbox be in /var/spool/mail <Sinner_> jaimie: you can set indivodual ones at ~/i18n <jtower> jeremyp: and i want it in ~/mail <jeremyp> jtower: I find the UW IMAP to be really annoying, as there's no config file, little documentation, etc. Tanner has it kinda figured out I think (but he did have to recompile) <jeremyp> Tanner has the UW-IMAP working in "blackbox" mode, delivering to /var/spool/imap/$USER instead of /var/spool/mail/$USER <JonC> I like UW, I've been playing with re-writing the POP <jtower> jeremyp: that's what i thought too, just wanted to be sure i wan't missing anything simple <JonC> Popd that is <jeremyp> (Blackbox mode meaning the user never reads the mail spool directly; they always go through IMAP) <jtower> but do user-created folders go there as well? <jeremyp> Look into the '.mbx' format which is a monolithic file like .mbox, but has some additional headers and such <jeremyp> jtower: yes, sorry, /var/spool/mail/$USER is a directory <jeremyp> the default folder is a file in that directory called INBOX <jeremyp> The advantage of .mbx is that you can have multiple IMAP clients reading the same mailbox(es) at once, without any locking issues <JonC> Hay where is the sylabus at these days? <jaimie> Sinner_: Are you keeping track of the syllabi? <Sinner_> yup <Sinner_> jaimie: yup <Sinner_> we'll have to modify the dates <Sinner_> I understand that we will have no "live" mmetings in the weeks tih a TriLUG meeting. <jeremyp> Does RHL 8.0 have "firstboot" or is that a Phoebe thing ? <RedWolfe> RH8.0 has it <jeremyp> I need to check into that. That's a configuration/administration thingy that will be new to the RHCE tests <Sinner_> thers'a a forstboot, yes <jeremyp> I think Phoebe moves more things out of the installer and into firstboot. I don't seem to remember firstboot when doing this current box, hmm... <jeremyp> (current box is RHL 8, that sentence didn't make too much sense...) <jtower> but firstboot in rh8 only runs in runlevel 5. what if you boot into runlevel 3? <jeremyp> I think that's what happened for me, I initially was setup in runlevel 3 <JonC> What is "firstboot" is that the script run on the first real boot into linus <jeremyp> So does that mean you get no opportunity to create a user if you install with runlevel 3 ? Because the "create-a-user" step is now done by firstboot, right? Or am I confusing things ? <JonC> s/linus/linux <JonC> What is the link to the Syllibus ? <jeremyp> http://www.trilug.org/~sinner/rhce.html <Sinner_> JonC: yup. it confirms KB, mouse, printer and things like that <RedWolfe> The "adduser" stuff still comes in anaconda, but there are additional set ups done in firstboot * Sinner_ announces that the dates and places will be modified to adapt to the change of venue <JonC> That's cool, Mandrake has done that for awhile now... <jeremyp> is firstboot a gtk+ tool like the redhat-confg-* stuff ? So it won't work if you only install KDE ? <Sinner_> jeremyp: is a framebuffer-python thingy <jeremyp> RedWolfe: okay, thanks. I think that changes in Phoebe though, hence my confusion <jtower> so does that mean i *must* boot into runlevel 5 to do those configs? cuz that would stoopid <Sinner_> you will be required to have some libs <Sinner_> ...b/c the same libs are used for redhat-config-* <Sinner_> jtower: yes <Sinner_> anyhow <Sinner_> by tomorrow I will ahve a new syllabus with new dates <Sinner_> as a proposal <Sinner_> let everybody know your thoughts about the new syllabus tomorrow <Sinner_> on the RCHE list <jeremyp> Sinner_: so do you want to have an in-person meeting next Wed or not ? <RedWolfe> Well, next Thur is TriLUG meet? right? <Sinner_> right <jeremyp> Lisa has updated her syllabus at http://www.trilug.org/~lisa/rhce2003.html also <Sinner_> jeremyp: I believe not <Sinner_> jeremyp: we could do a pre-config session on IRC <Sinner_> jeremyp: as config is a loooong subject <Sinner_> what do you all think? <jeremyp> I'm really sorry I wasn't ready to present tonight. I figured that we wouldn't have a location in time so that's why I didn't say up last night and get ready... <Sinner_> jeremyp: sleeping goes first <sweeper> jeremyp: don't worry about it <jeremyp> CyberToothTyger: okay, so which one of you is Jon Carnes, which one is Jaimie, etc.. ? <Sinner_> who is who? I know that I am me <Sinner_> most of the time <jaimie> Sorry. I'm switching to a different client. <jeremyp> Frankly two weeks from now would be best for me because I have a mid-term next Wed at 5:30 pm. But I really don't want to delay this any longer than possible <jaimie> KSirc is too hard to read for my worn out eyes. <JonC> Jaimie wants to know how to modify the fonts/colors by person and told him to try x-chat <Sinner_> jaimie_2: change fonts, get them bigger <jaimie_2> that's better <jtower> JonC: are you and jaimie like clark kent/superman or something? <RedWolfe> I'm flexible, any sched is pretty much okay <Sinner_> jeremyp: then it's all well. more time for oyur term exams, more time for the talk, no much disruption in calendar <jaimie_2> LOL <JonC> Yes, but I cant tell you which is which <jaimie_2> It's a secret <Sinner_> RedWolfe: the bigest prob is the clashes with TriLUG meetings <Sinner_> yo! <jaimie_2> I know there is a preference to keep the rhce meets on Wed, but HAHT's facilities are availble Mon-Sat after 6:30 <jasont> man, that jtower is such an idiot <RedWolfe> yow! <jp_home> there are too many j's here! <jpportz> jp_home: I'll say. <JonC> Saturday is cool with me! <jtower> i agree <jasont> no kidding <jaimie_2> Saturdays any time after 1pm. <sweeper> saturdays are pretty much out for me and Lisa <Sinner_> saturdays are pretty awful for me <jeremyp> Same here, I have a part-time job which is hard to work around <Dpsyno> That better? <ccw> make that 2 PM Sat for me. (Gotta listen to "wait wait don't tell me!' <Sinner_> ccw: you too? <ccw> :) yeah, love it! <Sinner_> :) * sweeper wanders off to have another fajita <Dpsyno> Note about Wed night meetings. We will be sharing the parking lot with a church that uses a part of the building. Just FYI. <Sinner_> Dpsyno: do they hate penguins? go they use Hasefroch? <jeremyp> Tribot: what are you ? <Tribot> i heard i was an infobot (http://www.infobot.org/) or an obstinate, ignorant, stupid bot that isn't worth the bits he's remembered by. <jtower> finally a reason to wear my marilyn manson t-shirt <jeremyp> Tribot: the syllabus is at http://www.trilug.org/~sinner/rhce.html <jeremyp> Tribot: the syllabus is also at http://www.trilug.org/~lisa/rhce2003.html <Tribot> okay, jeremyp. <Dpsyno> Sinner_: Don't know if they hate penguins or not. Just watch out for kids and old ladies walking blindly in the dark. <jtower> Tribot: where is the syllabus <Tribot> i think the syllabus is at http://www.trilug.org/~sinner/rhce.html or at http://www.trilug.org/~lisa/rhce2003.html <Sinner_> Tribot: Hasefroch is here: http://bulmalug.net/~bercab/HasefrochXP.jpg <jeremyp> Sinner_: is SinnerP taken? Why are you Sinner_ ? <Sinner_> jeremyp: sinner / Sinner / SinnerP / Sinner_ / Sinner_P is all the same <Sinner_> just a plain old sinner <ccw> jeremyp: why should I tell it my name? <jpportz> ccw: so we can use it to look up people's nicknames <JonC> The 2nd edition of ORielly's network security book just hit the shelves, anyone bought it yet? <jtower> jpportz: hey, he asked jeremyp , not you <jpportz> err.... <jeremyp> oops <Sinner_> BTW <jtower> i know, i know! By The Way <Sinner_> at B&N there's Red Hat Linux Firewalls 20% off <Sinner_> by RedHatPress <RedWolfe> by the way what? <Sinner_> and is about RH 8.0 <ccw> I entered my real name in the IRC session info. <JonC> very cool <jtower> the red hat press books are pretty good overall IMHO <JonC> If TriLUG library gets a copy of either book I would love to check them out - being poor and all <Sinner_> 523 pages including index <jtower> someone donated one to the trilug library this weekend <Sinner_> kwel <jeremyp> ccw: oh, in answer to your question "who started Tribot" -- it was originally started by Kevin Sonney ("alchemist") but Tanner Lovelace and I currently maintain it (it lives on the TriLUG server, moya) <ccw> cool, how does one barrow same? <JonC> I've noticed that the Wake Libraries carry a wide variety of the ORielly books <Sinner_> I must add that it's cheeper online that on the b&N shoppe <Dpsyno> Has anyone here taken the RH133 class? <jeremyp> The trilug library does have a new book, hold on and I can tell you the title of it... <jtower> i've seen running linux there many times but not many other orielly books <jtower> not at the garner library anyway, which says very little <JonC> Will the Librarian be at the meeting next week? <JonC> you can look at the whole system via their web-site and even suggest books to purchase <JonC> They'll even move books around to a convient library near you! <ccw> jeremyp: can you make it listen but not talk? <jtower> they have a whole collection of cisco books. heavy stuff too, like "building scalable multi-layered redundent networks" or whatever <jeremyp> The "new" book is _Maximum Linux Security_ from Sams. It's not Red Hat specific. Ask clotman on #trilug about it <jeremyp> JonC: I don't know. Some of the library's books are in the BBOS however, which will be at the meeting <ccw> jeremyp: ok, i'll bite, what a BBOS? <Dpsyno> Big Box o' Stuff <ccw> I had to ask ... <JonC> The SAMS books are *okay* but not as good as the ORielly books <jeremyp> The "o'" part is important, glad you got it spelled right, Dpsyno :) <Dpsyno> jeremyp: College warn't for nuthin. <Sinner_> what language is that? <Dpsyno> NC Redneck <Sinner_> I see <Dpsyno> Eastern Dialect <Sinner_> the first i18n language in RedHat <Dpsyno> Specific to the farming and fishing villages of the Albermarle region <Sinner_> cool <Sinner_> good to know <jtower> i got a parking ticket in albemarle last year <RedWolfe> Okracoke has a cooler dialect <jtower> $5 * Sinner_ likes languages, antropology, Linux and other wierd stuff <jeremyp> jtower: that Albemarle is not the one they were talkking about though <Dpsyno> Gimme Gullah... <jeremyp> The town of Albemarle is near Charlotte, the Albemarle sound area is near the coast <jtower> jeremyp: i know, but i wanted to tell my $5 parking ticket story really really bad <Dpsyno> Go, Go, Jeremy! You from Down East? <JonC> Did anyone read about the remote control surgery they did this week? <jeremyp> I got a $3 parking ticket from Durham Tech, so there :) <RedWolfe> track/sector/byte <JonC> The doc did the job remotely from a few hundred miles away <ccw> using what? <jeremyp> I didn't pay it. They're gonna have to deduct it from my paycheck if they really want it *grin* <Sinner_> JonC: I did <jtower> the $5 ticket was written on an envelope, you stuck a fiver in it and dropped in through a slot in the courthouse door <JonC> The details are up on /. <Sinner_> Dpsyno: BTW, I'm a resident in Greenville, NC <JonC> Now that is the kind of robots I would like to build <jeremyp> Dpsyno: pretty much lived in the Triangle my whole life so I try to stay knowledgeable about NC geography in both directions :) <jtower> not likely to star on battlebots though <Sinner_> JonC: it's pretty cool. although tele-healthcare is been around for a while <JonC> jeremyp: so you know where yonder is? <Dpsyno> Sinner_: My older bro', the psycho nut, lives in Greenville. Watch your back. ;) <Sinner_> Dpsyno: I see, so he has a brother, and it's you! <ccw> worked on tele-xray interp at UNC BME. <JonC> Sinner_: I know you and ChrisH have been helping tele-healthcare in the area <Dpsyno> Sinner_: Could be. The voices confuse me sometimes. <Sinner_> JonC: yes, and I was into healthcare IT before, back in Europe <jeremyp> JonC: yeah, Chris H lives over "yonder way" <jeremyp> Tribot: good one! <JonC> Sinner_: You guys doing anything interesting over there? <Sinner_> JonC: playing with hi-res monitors for medical imaging <jeremyp> ccw: Chris H is Chris Hedemark, a former active trilug member who's now in Pennsylvania <Sinner_> JonC: and using Linux servers for database (terabyte arcihvers and so on) <jeremyp> Hey Louis. <clotman> hey Jeremy <JonC> Sinner_: same ol same ol <Sinner_> JonC: and also owrking now on digital x-ray plaques available form everywhere east of Wilson :) <JonC> Sinner_: via web https <Sinner_> JonC: is there another way? <JonC> Well is there any more linux to talk about? <clotman> What time did you guys start the virtual meeting? <Dpsyno> Around about 8 <JonC> 8:00 <RedWolfe> abut 8 <Sinner_> clotman: at 8:00pm <Sinner_> I'm keeping logs <Sinner_> hahaha <jeremyp> clotman: we haven't really done much tonight <JonC> Sinner_: I hope you edit the logs! <Dpsyno> Has anyone here taken the RH133 class? <jeremyp> JonC: guess not really. <jeremyp> Dpsyno: which one is that again ? <Sinner_> JonC: sure :) <Dpsyno> sysadmin + rhct exam <jeremyp> Dpsyno: okay, that's what i thought. I took the RHCT exam <jeremyp> But I skipped the first 4 days of the class (the exam is on the fifth day) <Dpsyno> jeremyp: What's the exam like? <Dpsyno> jeremyp: Is it both multi-choice and hands on? <jeremyp> Dpsyno: http://www.redhat.com/training/rhce/courses/rh133.html <RedWolfe> Troubleshooting, Multiple Guess, System Install? <jeremyp> Dpsyno: it's just hands-on, a "troubleshooting" portion and an "isntallation and configuration" portion <jeremyp> No multiple choice. Only the RHCE has the multiple choice portion <clotman> This guy in my office says the RHCE has 50 percent failure rate. Anyone else heard that? <Dpsyno> jeremyp: What kind of trouble shooting? <Sinner_> clotman: I've heard that is worst <jeremyp> Dpsyno: see http://www.redhat.com/training/rhce/courses/rh133_content.html <JonC> clotman: look at the dregs that try to get certs... <jeremyp> clotman: I've heard worse than that <jeremyp> Dpsyno: there's an NDA so I can't really comment too much more unfortunately <Dpsyno> jeremyp: Ah. I C, said the blind man... <Dpsyno> Well, getting late. Gotsa go. Good night, all. <jeremyp> Dpsyno: good night. Hopefully we can have a more productive session next time <jeremyp> I will have some stuff prepared I promise <Sinner_> good night all <jeremyp> And then the regular meeting will be March 19th <clotman> Sinner_: Are you placing the notes on your site for this meeting? <Sinner_> clotman: of course <Sinner_> and tomorrow, There will be a first draft of proposed new schedule Generated by irclog2html.pl 2.1 by Jeff Waugh - find it at freshmeat.net!
