| |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. | 17:32 |
| |usefedora | Anyone have ideas on how to troubleshoot? | 17:33 |
| 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. | 17:34 |
| |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? | 17:36 |
| |usefedora | ogra_: any more ideas? | 17:43 |
| ac500 | help. my ubuntu server is churning file IO. | 18:10 |
| 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 | 18:11 |
| ac500 | im pretty new to linux servers but i cant figure out what i must have done wrong to get malware | 18:12 |
| 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 | 18:13 |
| 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 | 18:14 |
| 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* | 18:22 |
| bekks | tl;dr | 18:24 |
| 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 | 18:26 |

| bekks | Can you please form a full support question on one line, and watch your language please? | 18:30 |
| ac500 | what language? | 18:31 |
| 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? | 18:32 |
| 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 | 18:33 |
| 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. | 18:34 |
| ac500 | cat /var/log/mail.log | wc -l | 18:35 |
| ac500 | 594075 | 18:35 |
| ac500 | is that normal? | 18:35 |
| 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. | 18:36 |
| 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 | 18:37 |
| ac500 | i never installed sendmail myself unless i assume it comes with ubuntu server | 18:38 |
| bekks | You'd better worry about the other 99.73% I/O. | 18:39 |
| 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. | 18:40 |
| 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. | 18:42 |
| bekks | And not using enter is just nettiquette, not a guideline. | 18:43 |
| ac500 | depends on who you're talking to. | 18:43 |
| 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 | 18:44 |
| 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) | 18:46 |
| 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 | 18:47 |
| 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 | 18:48 |
| 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. | 18:49 |
| 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. | 18:50 |
| 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. | 18:51 |
| 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. | 18:52 |
| 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 | 18:53 |
| shredding | k | 18:54 |
| shredding | thanks | 18:54 |
