Comments:
<0> a bad idea surely?
<1> dunno. sci.crypt seems pretty useless these days - almost clueless
<0> pretty much describes usenet
<2> Jostein_: yeah, that quit
<3> Steakk: for a second I doubted your ***ual orientation :P
<4> Stand On Zanzibar
<5> Jostein_: you've known that for years. :D
<3> D-side: point
<6> I did not know you cold just DD a file to create a "Swap file". that's cool.
<3> New0rder: you know that mount can mount -anything- right?
<3> New0rder: like ISOs and stuff. why not a swapfile?
<4> must rest..later folks
<6> yeah. I know. but never thought of it
<6> good. needed that 128megs more swap space.. worked.
<6> heh.
<3> later all
<7> where do i set wich service run level start at startup?
<8> mounting "anything" is dependent on having support for the loopback device in your kernel
<2> AlexJ: inittab
<8> although I believe swapfiles are special cases
<3> Liandrin: but who doesnt? :P
<0> swap isn't 'mounted' as such
<7> and how do i swith to another runlevel?
<8> yeah, you use swapon instead of mount
<9> ooh a kittycannon
<2> fredk: i LOVE kittycannon
<9> 51ft
<9> haha
<7> ?
<2> 51 feet? thats it
<2> I had it over 3k before
<2> hit a LOT of explosives along the way
<9> first attempt, and I didnt try ;)
<7> how do i switch to another runlevel?
<0> telinit
<7> bash: telinit: command not found
<0> just init then
<7> nope
<7> can i switch over ssh?
<0> good bet
<7> a very good one :|
<6> Timing buffered disk reads: 342 MB in 3.01 seconds = 113.79 MB/sec
<10> hello there
<10> need help...our mail server is under attack
<10> someboby have any ideea ..how to escape?
<10> thanks
<11> stolniku: attack how?
<11> DoS?
<11> Brute-force?
<11> if the former you have to work with your ISP
<11> if the latter you have to work with your firewall
<10> thank you
<10> in our mail queue we have 10000 mails that ara not ours :(
<6> well, my stripe is a big faster then most of my linux servers (raid 10)... one of htem is 30meg/sec faster then mine.
<11> stolniku: then you have other problems
<11> stolniku: possibly an open relay
<11> so being used for SPAM
<11> mis-configured server
<10> i.m sure they cant send mail from our server...
<6> /dev/md0 466G 33M 466G 1% /mnt/gentoo
<12> Anyone have a Kodak camera on a 2.6 kernel?
<11> stolniku: in which case you wouldn't have a queue
<10> only the serveritself can't send
<11> devel: yes, but I prefer to use a card-reader
<12> the damn thing isnt even mounting as sda
<12> dmesg shows notta
<12> everything in kernel is great
<13> stolniku: time to call in the administrator.
<13> stolniku: or better yet: get someone qualified to administrate that box.
<10> there are a lot's of mail server phisicaly located in taiwan...that are connected on our server...
<11> devel: read up on gphoto
<11> devel: http://www.gphoto.org/
<12> stolniku: open relay problems?
<13> stolniku: time to check the logfile(s).
<8> I once came into work to find 90,000 bounced emails in the queue
<11> stolniku: it doesn't happend to run Sendmail?
<10> NO ..i have running Postfix a lot of time before
<10> no problems
<8> some spammer was sending emails to every conceivable email address at aol.com with <randomcrap>@<ourdomain> as the return address
<14> haha
<12> Im glad I dont do that anymore
<10> but now i use Oracle Collaboration suite
<11> Liandrin: that is why the recommendations is to disable bounce-messages
<13> lol
<13> stolniku: I think you should contact Oracle then :P
<8> the load was killing us, but AOL didn't even notice a spike
<11> hehe
<11> I'd just firewall aol
<8> they did automatically block us for spamming, though
<11> or was the traffic load heavy as well?
<8> has anyone else ever tried to get ahold of the AOL NOC? ;)
<11> thank god no
<8> K_F: well, think about it, tens of thousands of bounce messages per hour
<8> K_F: I don't recall the exact reason now that the messages were getting stuck in our queue
<11> inbound queue right? not outbound
<8> K_F, we ran one queue at the time
<11> yeah, but you yourself didn't bounce messages
<11> you got bounce messages from AOL
<13> K_F: adressed at non-existing accounts so it seems.
<8> we weren't generating bounce messages for AOL's bounces, if that's what you mean
<11> Lion-O: yeah, but a delete-all should do then
<11> Liandrin: yeah, it is
<8> I think we were trying to deliver them to the original sender
<8> but this is heading for a decade ago
<11> is the storage on another server, queue on NFS possibly
<8> and no matter how fast I manually cleared the queue of bounces, AOL was pouring them into us so fast the server was just ground into the floor
<11> or queue for the lookup if the users are stored in a DBMS
<11> can be a lot of reasons really
<10> thanks ---i will recheck config files
<8> oh god no, we experimented with NFS and mail for about fifteen minutes before we decided that was a Really Bad Plan(tm)
<11> Liandrin: but yeah, I can see it causing some pain
<11> Liandrin: good decision
<12> We use NFS
<12> to interface with out SAN
<11> Liandrin: my first step would be to firewall AOL, the second would be to have the ISP filter it
<12> Storedge 6850
<12> 14 Tera
<11> Liandrin: depending on the amount of data
<12> it runs fast
<12> over hba
<12> fiber
<12> just fine
<12> all our mail resides there
<8> K_F, we could have dumped everything going to or from AOL at our EGR, but we were already getting lots of complaints about problems with getting to/from AOL
<15> our mail spools are local to the mail servers, exported over NFS to the imap hosts.
<11> Liandrin: yeah, my users doesn't have anything to do with AOL so they wouldn't care
<11> Liandrin: but of course that is a consideration
<8> K_F, finally, we managed to get ahold of someone in AOL's NOC, who went to get the postmaster out of bed (!), and they resolved it in a few hours
<12> yea, I have no problem with it
<8> A few years later, when I lived near Washington, DC, I was good friends with AOL's head postmaster
<11> hehe
<11> Liandrin: that has got to be a stressful job
<11> with that amount of stupid users....
<8> he was a really smart and cool guy
<8> actually, it's weird, I knew a lot of AOL NOC staff when I lived in VA
<8> they were *all* really cool, *really* smart people
<11> Liandrin: yeah, the problem with AOL isn't the staff, but the users
<11> Liandrin: I used to have some contact with Opera Software and developers there, actually some I enjoyed going to a bar with
<11> usually I just get bored, nobody that is remotely interested in either computers nor finance / business
<11> heya Emerson
<11> Liandrin: now my problem is generally too little traffic and not too much, although I've gotten some DoSes
<11> Liandrin: my "favourite" was 26 GiB of "**** YOU" ICMPs
<11> and then there was a norwegian that attempted, bad move, the abuse department was rather helpful
<8> my husband was an Undernet IRC operator, I know all too much about being a DoS target
