[08:58] <lordievader> Good morning.
[14:19] <clyfe> my apache does not serve any requests, I can't seem to debug it ..
[14:19] <clyfe> trying to set a local development env
[14:20] <clyfe> Error code: ERR_CONNECTION_REFUSED
[17:32] <|usefedora> Hi, I changed my wlan0 to use a static IP by editing /etc/network/interfaces
[17:32] <|usefedora> And now it's refusing to connect.
[17:33] <|usefedora> Anyone have ideas on how to troubleshoot?
[17:34] <ogra_> |usefedora, https://wiki.debian.org/WiFi/HowToUse#WPA-PSK_and_WPA2-PSK
[17:34] <ogra_> see point 3
[17:34] <ogra_> that should suffice
[17:34] <|usefedora> ogra_: thanks, i'll have a look.
[17:36] <|usefedora> ogra_: i'd been using http://www.thefanclub.co.za/how-to/how-add-wireless-lan-adaptor-static-ip-ubuntu-auto-connects-startup
[17:36] <|usefedora> should i not use the hex encoded psk value that it says to?
[17:43] <|usefedora> ogra_: any more ideas?
[18:10] <ac500> help. my ubuntu server is churning file IO.
[18:11] <ac500> i think i have malware
[18:11] <ac500> iotop shows a process running "sendmail"
[18:11] <ac500> "sendmail: MTA: ./somehexstring from queue
[18:11] <ac500> and it just goes on like that indefinitely
[18:11] <ac500> i killed it
[18:11] <ac500> it came back in a few minutes
[18:12] <ac500> im pretty new to linux servers but i cant figure out what i must have done wrong to get malware
[18:13] <ac500> assuming this is malware
[18:13] <ac500> i dont know what to do though to remove it
[18:13] <ac500> i installed clamav and am going to try that
[18:14] <ac500> mostly though im wondering if this is a known problem (sendmail spinning all day long churning file IO)
[18:14] <ac500> because im new to linux and servers and it could be legitimate, but i cant figure out any legitmate reason to churn io and have "sendmail" running on a box i dont use mail on
[18:22] <ac500> nobody?
[18:22] <ac500> im seriously thinking of just reinstalling the os
[18:22] <ac500> though i hope i can learn something form this
[18:22] <ac500> from*
[18:24] <bekks> tl;dr
[18:26] <ac500> tldr: i think i have malware sending mail
[18:26] <ac500> tldr ubuntu security sucks if you want to get quippey :P
[18:26] <ac500> jk
[18:30] <bekks> Can you please form a full support question on one line, and watch your language please?
[18:31] <ac500> what language?
[18:32] <bekks> Impolite language.
[18:32] <ac500> like "tldr"?
[18:32] <bekks> Like your opinion about ubuntu security.
[18:32] <ac500> question: is theres something wrong when iptop shows a "sendmail" process running perpetually, when I have none of my own mail use on this box?
[18:33] <bekks> No, there is nothing wrong. If your server is idleing so much that even sendmail makes it up to the top ten, then every is alright.
[18:33] <ac500> the HD is churning heavily
[18:33] <ac500> when i kill it the audible churn stops
[18:34] <ac500> IO >90% from iotop
[18:34] <ac500> iirc (ill check again when it starts up again)
[18:34] <bekks> The check the sendmail logs whats going on.
[18:35] <ac500> cat /var/log/mail.log | wc -l
[18:35] <ac500> 594075
[18:35] <ac500> is that normal?
[18:36] <ac500> filled with stuff like:
[18:36] <ac500> Mar 23 08:21:19 computebox sm-mta[10463]: s2K6l55T009136: Warning: program /usr/sbin/sensible-mda unsafe: No such file or directory Mar 23 08:21:19 computebox sm-mta[10463]: s2K6l55T009136: SYSERR(root): Cannot exec /usr/sbin/sensible-mda: No such file or directory Mar 23 08:21:19 computebox sm-mta[5310]: s2K6l55T009136: to=root, delay=3+08:28:41, xdelay=00:00:00, mailer=local, pri=43500000, dsn=4.0.0, stat=Operating system error
[18:36] <ac500> .... and the disk noises have started up again
[18:36] <bekks> Then check your sendmail installation. Note the "no suche file..." messages.
[18:37] <ac500> hmm well its not 90% like i thought at least
[18:37] <ac500> you might be right, its jsut 0.27% IO but still making ht disk churn audibly until i kill it
[18:38] <ac500> i never installed sendmail myself unless i assume it comes with ubuntu server
[18:39] <bekks> You'd better worry about the other 99.73% I/O.
[18:40] <ac500> oh yeah
[18:40] <ac500> it was some archive manager
[18:40] <ac500> or something about dfile system archiving i think
[18:40] <ac500> but yeah now that i killed it
[18:40] <ac500> the 99% io is gone
[18:40] <ac500> now that i killed the sendmail thing, that is
[18:40] <ac500> it'll come back in a few minutes like it always does
[18:40] <bekks> Can you please NOT use enter as a punctuation sign?
[18:40] <bekks> Thank you.
[18:42] <ac500> are there rules for chat for this channel i can read somewhere?
[18:42] <bekks> https://wiki.ubuntu.com/IRC/Guidelines
[18:42] <ac500> i see no mention of punctuation.
[18:43] <bekks> And not using enter is just nettiquette, not a guideline.
[18:43] <ac500> depends on who you're talking to.
[18:44] <bekks> To make it pretty easy for you: if you want to continue talking with me, dont use enter as a punctuation sign. Thank you.
[18:44] <ac500> i'd rather get my tech advise from someone who is mentally stable
[18:44] <ac500> you may want to see your doctor about OCD or something of that sort
[18:44] <bekks> ac500: Ignore set. Good luck.
[18:44] <ac500> thanks you.
[18:44] <ac500> :P
[18:46] <ac500> wow i hope all of the ubuntu community isnt as abrasive and demanding (whining about punctuation, reacting with 'tldr' when nobody else is in the room, etc) as bekks
[18:46] <ac500> im going to go try the centos forums even though thats a different distro, and maybe move over if they're more friendly
[18:46] <ac500> i mean irc)
[18:47] <shredding> I'm learning system administration and http://wiki.ubuntuusers.de/IP-Adresse_wechseln says that I can edit my ip address in  /etc/network/interfaces
[18:47] <bekks> shredding: Yes, it does.
[18:47] <ac500> i was able to do that
[18:47] <ac500> its only on a local level though
[18:48] <shredding> Did I misunderstood something fundamentally on the internet or can everyone just say: This is my ip address?
[18:48] <ac500> (of course) so you cant change your public ip
[18:48] <shredding> How do I know if it's already in use.
[18:48] <ac500> no you cant do that
[18:48] <ac500> thats up to your ISP
[18:48] <bekks> shredding: you did misunderstand something fundamentally. :)
[18:48] <ac500> the IP address you assign is just local to your home router / network
[18:48] <shredding> That's what i thought ac500
[18:48] <ac500> but this helps though
[18:48] <ac500> so for example i set up a script that updates my DNS every 5 minutes to whatever my public IP is
[18:48] <bekks> shredding: you have to use the IP adress(es) assigned to you by your internet provider.
[18:48] <shredding> so, if i have a server, which network is meant there?
[18:48] <ac500> then my router forwards the traffic to the static local IP i set for my linux box
[18:49] <sheptard> shredding: there's also reserved ranges that are used for internal networks
[18:49] <bekks> shredding: Ask your server provider.
[18:49] <sheptard> shredding: You can use any of those to your hearts content
[18:49] <shredding> Okay, so it's a private network on behalf of my server provider.
[18:49] <bekks> No.
[18:49] <sheptard> bekks: he might be nat'd you never know
[18:49] <bekks> It is a public network which is devided into subnets which are administered by different providers.
[18:50] <shredding> bekks: What is a public network?
[18:50] <shredding> I'm referring to that network that hosts the ip in my  /etc/network/interfaces
[18:50] <bekks> shredding: the opposite of the "private" network you mentioned seconds ago.
[18:51] <bekks> shredding: You have to know which IP was assigned to you by your provider. This IP is to be setup in /etc/network/interfaces
[18:51] <shredding> Okay, but the ip in  /etc/network/interfaces belongs to a private network.
[18:51] <bekks> shredding: Where is that server located?
[18:51] <shredding> it's not a specific server, I want to understand how it works.
[18:51] <shredding> but for the sake of this discussion, say it's digitalocean
[18:51] <shredding>  /etc/network/interfaces comes preconfigured there.
[18:51] <bekks> Then ask digitalocean which IP they assigned to you.
[18:52] <shredding> And that's the one in  /etc/network/interfaces?
[18:52] <bekks> If it is located in your home LAN, then assign an IP from the network you are using.
[18:52] <shredding> Okay, i come to understand: The ip in  /etc/network/interfaces is not the ip that connects to "the internet" (e.g. is publicly available) but to the network of my server provider.
[18:53] <shredding> And that network is connected to an isp.
[18:53] <shredding> Is that close to the truth?
[18:53] <bekks> shredding: No.
[18:53] <shredding> damn
[18:53] <bekks> Far away actually.
[18:53] <bekks> shredding: Since this is far beyond ubuntu support, and since you are reading german actually, you're better of in #ubuntu-de-offtopic
[18:54] <shredding> k
[18:54] <shredding> thanks
