• How to find malicious IPs?

  - by alfish

  Cacti shows irregular and pretty steady high bandwidth to my server (40x the normal) so I guess the server is udnder some sort of DDoS attack. The incoming bandwidth has not paralyzed my server, but of course consuming the bandwidth and affects performance so I am keen to figure out the possible culprits IPs add them to my deny list or otherwise counter them. When I run: netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n I get a long list of IPs with up to 400 connections each. I checked the most numerous occurring IPs but they come from my CDN. So I am wondering what is the best way to help monitor the requests that each IP make in order to pinpoint the malicious ones. I am using Ubuntu server. Thanks

• Strange PHP output buffering

  - by radek-k

  PHP: header('Content-type: text/plain'); for ($i=0; $i<10; $i++){ echo "$i\r\n"; ob_flush(); flush(); sleep(1); } I tried script above on 2 different servers. Both respond numbers 0...9 in every line. In case of first server each number is received every second. In case of second server there is no output for 10 seconds and entire output is displayed at once. What might be wrong int second case? I tried various uutput control Functions but it didn't help. Set of response headers in both cases is pretty much the same: HTTP/1.1 200 OK Date: Mon, 03 Jan 2011 19:21:21 GMT Server: Apache X-Powered-By: PHP/5.2.14 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/plain

• Why is "chmod -R 777 /" destructive?

  - by samwise

  This is a Canonical Question about File Permission and Why 777 is "destructive". I'm not asking how to fix this problem, as there are a ton of references of that already on Server Fault (reinstall OS). Why does it do anything destructive at all? If you've ever ran this command you pretty much immediately destroy your operating system. I'm not clear why removing restrictions has any impact on existing processes. For example, if I don't have read access to something and after a quick mistype in the terminal suddenly I now have access well... why does that cause Linux to break?

• Connecting to iSCSI Target

  - by Joost Verdaasdonk

  I've installed Microsoft iSCSI Software Target 3.3 on a server 2008 R2 machine and created a new iSCSI Target. In the target I created a new Virtual Disk. From another server I started iSCSI Initiator and in Targets | Target I typed the IP of the Target. (Also tried DNS name.) But when I click Refresh I never see the target. Through googling I found this Youtube tut from a French guy doing pretty much what I did (only difference is I'm in a domain). I first though that maybe Port 3260 was closed but its not I can telnet to it. Also disabled all firewalls to see if that was blocking anything... No luck so far. Does anybody know of possible reasons why I can't connect to the iSCSI Target? If I can provide more info please let me know what's needed? Extra info: I've used this tut to set things up.

• How to configure something like "Reflexive ACL" on OpenBSD?

  - by Earlz

  My U-Verse modem has something called "Reflexive ACL" described as Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). This seems like a pretty good way to keep from having to maintain a firewall on each computer behind my router that gets handed an IPv6 address. It sounds about like a NAT, which for my small home network is all I want right now. Now my modem sucks as a router though, so I'm in the process of configuring an OpenBSD router to do that. I've got IPv6 supported and all that and my OpenBSD router will hand out IPv6 addresses by rtadvd. Now I want to keep people from having instant access to my local network through IPv6. How would I best do something like Reflexive ACL with pf in OpenBSD 5.0?

• Why is 'grep -i' so slow? How to do it faster for ASCII?

  - by Vi.

  Consider: $ time lzop -d < tvtropes-index.lzo | egrep -B 5 '[Dd][eE][sS][cC][eE][nN][dD] ?[Ff][rR][oO][mM]' real 0m0.438s $ time lzop -d < tvtropes-index.lzo | egrep -B 5 'descend ?from' -i real 0m11.294s Both search case insensitively. Why is the -i version so slow? How do I make grep -i fast without entering things like [iI][nN] [tT][hH][iI][sS] [wW][aA][Yy]? For example, perl -ne 'print if /descend ?from/i' works fast, but '-B 5' is not as trivial to implement as in grep (as well as other options).

• My computer gets hosted when using 3G

  - by WeaklyTyped

  I recently activated 3G(UMTS) connection on my cellular network. I use Nokia S60 phone as a modem while connecting from Scientific Linux 6. While I am able to access net pretty well, the problem is my computer gets hosted. By using ip-address in a web-browser, anyone can access my localhost (running apache), this never happens with my wireline (ADSL) connection. Furthermore, even the Shell prompt changes from: [mach2@localhost ~]$ to [[email protected] ~]$ where XX.XX.XX.XX is the IP of the 3G connection. The very thought of putting my machine 'in the wild' is disconcerting. How can I rectify the situation without disabling services like apache, sshd and others?

• Comparison of Unix shells

  - by Andy White

  Of the major Unix shells (bash, ksh, tcsh, zsh, others?), are there any compelling reasons to use one over another? Which is the most interactive/command-line friendly? Which is the most conducive/intuitive for writing scripts? Are there any major built-in features that one shell offers that others don't? Are any of these shells really good for one type of function, but not another? Or are they all pretty well-rounded/flexible? Is it just a matter of personal preference? I can make this community wiki if anyone prefers.

• Why doesn't openSUSE Linux upgrade itself through its software repositories?

  - by Dougal

  openSUSE - fast becoming my favourite Linux distro on the client - doesn't seem to upgrade itself through its own configured software repositories. Do we know why this is the case? Is it a money-making thing where they can then sell upgrade CDs / DVDs? I mean, pretty much every other Linux upgrades itself through the normal software repositories. For example, Ubuntu can upgrade itself from 10.4 to 10.10 just through the normal software package upgrade procedure. Why must it be a huge procedure to upgrade openSUSE? Any knowledge or ideas appreciated. Thank you.

• Disadvantages of using a swap file/partition on an SSD, even when swappiness is set to 0

  - by pjv

  What are the disadvantages of using a swap file/partition on an SSD, even when swappiness is set to 0 I'm particularly interested in the /proc/sys/vm/swappiness=0 case. How much writes are still done, in practice, to that swap file, and does it have a negative impact to the SSD or any other disadvantage? Or would it nearly compare to not having a swap file? I am pretty aware of what swappiness=0 means, just not of what it amounts to in practice. My question stems from a problem I am experiencing without a swap: http://stackoverflow.com/questions/4567972/error-executing-aapt-all-of-the-sudden. There are similar questions regarding SSD and swap but they don't go in-depth into the swappiness=0: Disadvantages of not having a swap partition, Should I keep my swap file on an SSD drive?

• -w test on OS X gives command not found error

  - by RobV

  I'm writing a bash script which I'm testing on OS X though it will ultimately run on a standard Linux environment and running into a weird error. I have tests like this in my script: if [ ! -w $BP ]; then echo "'$1' not writable" exit 1 fi Which seems pretty sane to me and works fine under Linux but when trying to test on OS X I get the following error message: startSvr.sh: line 135: [: missing `]' startSvr.sh: line 135: -w: command not found So is this a case of OS X not supporting the -w test or is there some other reason this isn't working for me? e.g. environment

• Can the JVM(Oracle) run into an OutOfMemory error if the heap size is below the max?

  - by user439407

  I am running a Tomcat site(with an NGinx front end) that seems to be randomly running out of memory even though the max heap size is pretty large. My question is is it possible for the JVM to get an OutOfMemory error even if the heap size is significantly less than -Xmx? For instance, here is a snapshot I took just 15 seconds before an OutOfMemory error: Tue Dec 18 23:13:28 JST 2012 Free memory: 162.31 MB Total memory: 727.75 MB Max memory: 3808.00 MB I guess theoretically it's possible that my code generated 3 gigs worth of objects in 15 seconds, but I highly doubt it. It seems like the JVM was unable to grow the heap even though it theoretically had room....Is it possible that other processes started using memory to the point that the JVM could not grow? I am running 64-bit Oracle Hotspot on a 64 bit vm running CentOS 5 with 6 gigs of ram.

• Why doesn't this batch file work for me?

  - by asdfg

  The following batch file is not woking. @echo off python -c "print('echo text')" %TEMP%\test.bat call %TEMP%\test.bat Can anyone help me with this?. edit: I needed unix eval functionality in windows. I could not find a direct way though. So I redirected the eval string to a temporary batch file and executed it. The temporary batch file was successfully created but calling it did not work in the above case. I noticed that any command after the test.bat creation did not work.

• IOS not saving evaluate rule in access-list

  Hi. I have a basic firewall set up on an pretty od IOS in form of IPv6 access list exterior-in6 evaluate exterior-reflect sequence 1 permit ipv6 any host [my external address] sequence 10 permit tcp any host [my internal address] eq 22 sequence 11 permit icmp any any sequence 800 permit udp any any range 6881 6889 sequence 900 permit tcp any any range 6881 6889 sequence 901 deny ipv6 any any sequence 1000 IPv6 access list exterior-out6 permit ipv6 [my internal subnet] any reflect exterior-reflect sequence 10 Unfortunately the evaluate exterior-reflect sequence 1 line seems to get lost after each reboot, leaving my internal network without access. Any ideas?

• Use Backup Exec configuration 2010 R3 file on 2012

  - by Roger M

  I'm looking to upgrade my backup solution from Symantec Backup Exec 2010 R3 (Which i believe is the same version as 13) to Backup Exec 2012. Now, it's pretty easy to open BEutility and use the "Copy media server configuration"-function in 2010 R3, but I have not found any answers as to whether this file can be imported flawlessly into 2012 or not. It would save loads of time if it's doable. Since I HAVE TO remove the 2010 installation before installing 2012, it's not possible to just test it. I need to know before I go through with it. Anyone who's tried the same? PS: Running Windows Server Standard 2008 R2

• How do I configure ubuntu server's iptables to allow java without opening the floodgates?

  - by rofls

  I'm new to servers, so please bear with me. I have my amateur site running. Problem is, I followed Rackspace's instructions on setting up iptables and am pretty sure that's why the java server I'm trying to use on port 8080 isn't working (it runs the script but my android test app doesn't connect to it). When I try running the same java server script on port 80 it doesn't even start. I also ran nmap on my domain and saw that indeed only port 80 and 22 (for ssh) are responding. Is it possible to run Java and apache happily on the same server? If so, how can I configure my iptables correctly. (I'm aware that I should probably do some sort of filtering in the java server itself, but will figure that out later).

• Clean logging with BASH

  - by Matt Krouse

  I have a script that deletes files 7 days or older and then logs them to a folder. It logs and deletes everything correctly but when I open up the log file for viewing, its very sloppy. log=$HOME/Deleted/$(date) find $HOME/OldLogFiles/ -type f -mtime +7 -delete -print > "$log" The log file is difficult to read Example File Output: (when opened in notepad) /home/u0146121/OldLogFiles/file1.txt/home/u0146121/OldLogFiles/file2.txt/home/u0146121/OldLogFiles/file3.txt Is there anyway to log the file nicer and cleaner? Maybe with the Filename, date deleted, and how old it was? Any suggestions help!

• Reverse Proxy to filter out js files from multiple hosts in nginx

  - by stwissel

  I have a website http://someplace.acme.com that I want my users to access via http://myplace.mycorp.com - pretty standard reverse proxy setup. The special requirement: any js file - either identified by the .js extension and/or the mime-type (if that is possible) text/javascript needs to be served from a different location, a local tool that inspects the js for potential threats. So I have location / { proxy_pass http://someplace.acme.com; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; proxy_redirect off; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~* \.(js)$ { proxy_pass http://127.0.0.1:8188/filter?source=$1; proxy_redirect off; proxy_buffering off; } The JS still is served from remote and I have no idea how to check for the mime type. What do I miss?

• Cygwin creates files with special (shared) icons on windows

  - by barjonah

  I use cygwin to transfer files between linux and windows machines. Everytime I transfer a file to a windows machine it adds an extra shared user icon on the file's or folder's icon itself. This also happens if I create a file from cygwin on windows using pretty much any command: echo, vim, nano, cat. This is what the cygwin-created folders (and files) look like. This is what a normal folder (or file) looks like. I'm thinking it has to do with permission, because I'd have to chmod it everytime if I want other applications to access the files or folders on windows. How can I tell cygwin to create regular ol' files just like a user or any program would?

• Photoshop changes colors when moved to a different monitor

  - by Jason

  This Yahoo! answers question pretty much sums up my predicament. Unfortunately I haven't really found an actual answer. Here's a screen shot of what happens when I place Photoshop between my monitors. Imagine that the left side of my laptop is the right square and the yellow is the right side of my monitor. When I move the program to one side fully or the other, it takes on the corresponding color. Obviously the color on the right is correct and Photoshop is changing the color of the image when it moves to my external monitor. Also notice how none of the tools or anything are different colors, just the actual image itself. How do I fix this? EDIT You may also notice that the color palette in the left corner is showing that yellow tinge. I didn't actually pick that yellow color, it's supposed to be showing the grey on the left that I used to fill in the square.

• How do i set a (open_)basedir with php using fastcgi/nginx?

  - by acidzombie24

  Essentially i found out you can limit the folders each user has access to by using php's basedir/open_basedir. I'd like to have each php only access its own files. So i wrote fastcgi_param open_basedir $document_root; in hopes that it would work. It didnt. I googled and only found results saying you cant do it via fastcgi or nginx. Is this true or can i not do it? PS: I -do- spawn php as its own user (rather then www-data) so it doesnt wreak havoc on my nonphp websites. But i still like to prevent one php script on a php site from accessing other directories (if i have a wordpress install on yourface.com its pretty obvious a valid php path is /var/www/yourface/<wordpress scripts>

• Monitoring the wall time of a process on windows?

  - by Sean Madden

  Windows Task Manager has the ability to show the current CPU time of any given running process on windows, is there any way (not necessarily through Task Manager) to get the current wall time of a process? An example, let's say I have a script that reliably runs for about 45 minutes. Without adding a progress bar to the script, is there any way to figure out for how long it has been running? The math behind this seems pretty straight forward; WallTime = CurrentWallTime - WallTimeProcessStarted. Likewise, since the math is so simple, is there anyway to get the time that a process was started at?

• Is it possible to have tab completion of drop-down lists in web pages in Firefox?

  - by Nick Booker

  Does anyone know of a Firefox plugin that would enable tab-completion (or some other key sequence like Alt-L) of items in drop-down lists in web forms? e.g. ou<TAB>in<TAB>s<TAB> for 'OurCompany - Internal Support' Vimperator's hints mode makes it very ergonomic to focus the drop-down list with a key sequence like f13 but the keyboard interface to the drop-down list still sucks. I very frequently have to pick items from a very long list with very long common prefixes among the entries (e.g. 30-40 starting with OurCompany -), which renders both the built-in keyboard interface and the mouse pretty slow and unergonomic. I basically want readline support for filling webforms!

• How do you create a SQL query in Excel 2007 with a dynamic date range?

  - by Jordan

  I am trying to create a reporting spreadsheet that can print reports for a given time period. The query below works, but when I try to use a "?" parameter in place of the date, I get an error after selecting a cell containing my date. If I use single quotes ('?') I get a conversion from string to date/time failure, if I don't (?) I get a syntax error near @p1. Eventually I will need either a start and end date or a formula adding a month or shift to the starting date/time to filter the data down to important information. The query was built in Microsoft Query. SELECT FloatTable.DateAndTime, TagTable.TagName FROM master.dbo.FloatTable FloatTable, master.dbo.TagTable TagTable WHERE FloatTable.TagIndex = TagTable.TagIndex AND ((FloatTable.DateAndTime={ts '2012-06-01 00:00:00'})) Any assistance would be much appreciated. Thanks in advance.

• How To Adjust Properly Brightness And Contrast On Monitor

  - by Johannes

  This days, it seems that I either go worse with my eyes or some settings with contrast and brightness have been changed. However, I have been searching now for some tutorial on how to adjust contrast and brightness, and I have found already some, on how to use Microsoft Win7 Calibrate Display Color program, but some people don't recommend it.. My monitor control menu shows settings (which are by default) that contrast is set to 80, contrast to 90 and sharpnes to 45, for which I belive are pretty dam high. I'm usually every day in front of my PC about 6-10h. The biggest problem is, when the night comes, and I have to read some word document, after a 10-15m of reading, eyes starts hurting. I'm using ASUS VW198 and Nvidia 9800 GT graphic card. So please suggest me, what should I decrease, contrast or brightness or both?
