• php extensions & apache mods gone/not working after server restart?

  - by user1782359

  I was wondering if anyone has ever come across this before, as I'm pretty stumped to be honest, and my server admin knowledge isn't particular good so I'm not sure what could even be wrong, let alone how to fix it. Basically, Thursday last week everything was fine on our server. I come in on Friday and it's a mess: php extensions are missing/not working, apache modules are gone. (e.g. oci_* was gone completely, odbc_ not working but still there, the apache ntlm_auth for single sign on was gone and so the website wasn't even loading in IE). I'm ruling out anything deliberate because it's just incredibly unlikely. The only thing that really happened between thursday & friday is that on thursday evening one of the network guys did a RAM upgrade on the server and restarted it. That's it, nothing else. Now I'm wondering if somehow those extensions and such which we installed months ago were somehow only saved in a local memory of sorts, and a restart has wiped them? But we installed them all as root, so I don't see why it should be any different from installing anything else. It makes little/no sense to me. To expand on an example of something that's gone very wrong, the php odbc_ extension: It's still on the server, it doesn't return undefined function or anything. But it just cannot connect to the datasource any more. I've tested it through the command line and it's working perfectly fine with that datasource and login details, but all of a sudden having it in the php odbc_connect() function and it just can't connect. ( [S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source. ) But unixODBC is set up fine. Like I say i've tested it all through the terminal and it can connect, and we've not changed anything, it's just now all of a sudden not working through the PHP function. Anyone have any ideas whatsoever as to what could be going on? This is on CentOS 5.x by the way.

• empty file from tomcat https redirect?

  - by amertune

  I am using tomcat 6.0.20, with jdk 1.6.0_18 on 64 bit linux (tomcat downloaded from tomcat.apache.org, not installed from repositories). I have iptables redirects from port 80 - 8080 and 443 - 8443. In server.xml, the connector for port 8080 redirects to 443, and the 8443 connector has proxyPort="443". In conf/web.xml, I have added this bit at the end of the file (but still inside the <web-app</webapp tags). <security-constraint> <web-resource-collection> <web-resource-name>Protected Context</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <user-data-constraint> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint> I also have two contexts, ROOT and mywebapp. If I go to http://myurl.com, then I get redirected to https://myurl.com. If I go to http://myurl.com/mywebapp/, then I get redirected to https://myurl.com/mywebapp/. The problem I'm having is when I go to http://myurl.com/mywebapp (no trailing slash). When I do this I get a prompt to download an empty file that has an empty name. Going to https://myurl.com/mywebapp works. I would think that a user typing myurl.com/mywebapp is far from rare. Is there something I'm missing?

• (updated) Subfolder needs whitelist and standard redirect for all others

  - by Superstrong

  How can I allow access to the foo.html files in the .com/song/private/ subfolder for: a logged-in Wordpress user; or any referral domains (including subfolders) I add; or any URL on our own domain from the com/song/private folder; For all others, the user should be redirected to the corresponding public version of the Post, which is the same html filename and structured .com/song/foo.html. (The private versions uses a different template with different custom fields for each Post.) Update: Here's what I have so far: <Limit GET POST> order deny,allow deny from all allow from domain.com/song/private allow from otherdomain.com </Limit> RewriteRule ^(.*)$ ../$ [NC,L] More: Will that last rewrite rule take people back to the public version, from com/song/private/foo.html to com/song/foo.html? I found the following rule for detecting Wordpress logged-in status, but what do I put aferward with a RewriteRule, and will it work anyway? (If not, is there an alternative?) RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in_.*$ N.B. I have added code to my root .htaccess allowing me to insert additional .htaccess files in other subfolders as needed. Copied from Stack Overflow, where they suggested I ask here.

• auth user and exec a node app only with apache?

  - by Blame

  I couldn't find an answer on the web and I'm trying for days now so I hope that someone with more experience with apache can help me out. Iam writing an web editor and the user should be able to edit a file that is on the server in a directory the user has access to. The problem Iam facing is that I need to authenticate against the system users (shadow/passwd). So the user should be able to login whith a system account and then the node app which does all the logic should be started with the users rights. I hope to get this working without any additional script and only with Apache. I found out two things: I can use mod_auth_pam to authenticate the user There is a mod called suEXEC which can exec the node app with a specified user The problem is that I have to hard code which user is used by suEXEC but I want to decide when the user logs in. Is there any way to authenticate a user against the shadow/passwd and then exec a prog with the users rights? I dont want to run the node app as root and the user should only be able to access his own files. Any help would be appreciated! Thanks, Kodak

• building a debian base image

  - by Michael

  Is there a preferred way to create base images for Debian-based customized installations? We are currently going with multistrap but although it's better than hand-crafted chroot stuff, it still has a lot of edges and corners. Is there a more reliable and less error-prone way to produce a root filesystem of a Debian installation with some additional .debs installed? (I don't want to send out a Debian installer with a preseed file though.) Addendum 1: To clarify things a bit: We are delivering some kind of software appliance to our customers. That is, a debian operating system, with some additional software packages -- both our own and third-party ones -- and some configuration changes. To ease the installation process, we have an installer that does nothing more than partitioning, copying files to the partitions and setting up grub. So it's basically an image-based installer. So we are basically running the debian installation ourselves and just distribute the already installed operating system. The question is about the installation part. I want to have that as easy and robust as possible, and of course, it should be an automated process.

• erratic response times with Apache 2.0.52 on redhat 4.

  - by Kevin

  Under load, we've noticed response times from Apache vary greatly for the same 7k image. It can range anywhere from .01 seconds to 25 seconds or greater. Unfortunately, due to corporate policy constraints we are pretty much stuck on Apache 2.0.52. I'm at best an Apache novice so I'm in over my head with this problem. My focus recently has turned to our choice of MPM modules. We use the worker model on a dual core hyper threaded blade. It doesn't appear that swapping is an issue, and I don't see any signs of a hardware problem. I've read that worker is optimal on hardware with many CPU's where prefork it more suitable for our specific hardware profile. I can see conceptually how choosing the wrong MPM could result in this erratic behavior, but I'm not confident that it's the root cause here. Has anyone else seen this type of range in your response times for simple static content? What else should I be looking into here?

• IPTables configuration help

  - by Sam

  I'm after some help with setting up IPTables. Mostly the configuration is working, but regardless of what I try I cannot allow localhost to access the local Apache only (i.e. localhost to access localhost:80 only). Here is my script: !/bin/bash Allow root to access external web and ftp iptables -t filter -A OUTPUT -p tcp --dport 21 --match owner --uid-owner 0 -j ACCEPT iptables -t filter -A OUTPUT -p tcp --dport 80 --match owner --uid-owner 0 -j ACCEPT Allow DNS queries iptables -A OUTPUT -p udp --dport 53 -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT Allow in and outbound SSH to/from any server iptables -A INPUT -p tcp -s 0/0 --dport 22 -j ACCEPT iptables -A OUTPUT -p tcp -d 0/0 --sport 22 -j ACCEPT Accept ICMP requests iptables -A INPUT -p icmp -s 0/0 -j ACCEPT iptables -A OUTPUT -p icmp -d 0/0 -j ACCEPT Accept connections from any local machines but disallow localhost access to networked machines iptables -A INPUT -s 10.0.1.0/24 -j ACCEPT iptables -A OUTPUT -d 10.0.1.0/24 -j DROP Drop ALL other traffic iptables -A OUTPUT -p tcp -d 0/0 -j DROP iptables -A OUTPUT -p udp -d 0/0 -j DROP Now I have tried many permutations and I'm obviously missing everything. I place them above the in/out bound SSH to/from, so it's not the precedence order. If someone could give me the heads up on allowing only the local machine to access the local web server, that'd be great. Cheers guys.

• How to set up a server without a hosting control panel

  - by A4J

  I have always used a control panel on my dedicated servers - from cPanel to Plesk to Virtualmin, and I am now considering ditching a CP altogether and manually editing config files. My requirements are fairly simple, I will host multiple sites on the server; some Apache with PHP & Mysql and some Passenger with Rails & Postgres. All will require email smtp/pop. FTP/Stats will not be required. Could someone please give me a quick run-down of what I would need to do - in terms of installing software and configuration? My server will come with a base install of CentOS 6.4 minimal. My thoughts so far: Install/update latest versions of MySQL & Postgres (are they 'safe' out of the box? Or do I need to do anything else like set up root passwords etc?) Install Apache & PHP (again, are the base installs good to go or do they require security tweaks?) Set up nameservers/hostnames/reverse DNS etc (Any guides on how to do this please?) Install Rubygems Install and configure Dovecot and Postfix (any tips on doing this? Or links to how-tos that cover it please?) Set up each website - any links to guides on how to do this? Install/configure firewall (or is the default install good to go?) Any other tips or advice would be greatly appreciated, as would links to guides or how-tos.

• vmware player won't run on CentOS due to missing /dev/vmmon, what could be the problem?

  - by Graphics Noob

  So I've tried installing vmware player 3.1.4 and 3.1.3 and both times had the same problem, when I try to load a VM I get the error "Could not open /dev/vmmon". When I ls /dev/ I can see there is no "vmmon" device present. When I try running: sudo /etc/init.d/vmware start I get the output: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [FAILED] which shows that the Virtual Machine Monitor fails to load. I tried following the advice on this site and ran vmware-modconfig --console --install-all I notice during the compilation there are no errors, but at the end I get the message: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [ OK ] Unable to start services Out of curiousity I tried: sudo /sbin/insmod /lib/modules/2.6.18-238.9.1.el5xen/misc/vmmod.ko But got the error message: insmod: error inserting 'vmmon.ko': -1 Invalid module format I have a feeling this may be the root of the problem, but I don't know what could be causing it or how to fix it.

• File permissions on web server

  - by plua

  I have just read this useful article on files permissions, and I am about to implement a as-strict-as-possible file permissions policy on our webserver. Our situation: we have a web server accessed through sftp by different users from within our company, and we have the general public accessing Apache - sometimes uploading files through PHP. I distinguish folders and files by their use. So based on this reading, here is my plan: All people who need to upload files will have separate users. But all of those users will belong to two groups: uploaders, and webserver. Apache will belong to the group webserver. Directories Permission: 771 Owner: user:uploaders Explanation: to access files in the folder, everybody needs to have execute permission. Only uploaders will be adding/removing files, so they also get r+w permission. Files within the web-root Permission: 664 Owner: user:uploaders Explanation: they will be uploaded and changed by different users, so both owner and group need to have w+r permissions. Webserver needs to only read files, so r permission only. Upload-directories Permission: 771 Owner: user:webserver Explanation: when files need to be uploaded, Apache needs to be able to write to this directory. But I figure it is safer to change the owner to webroot, thus giving Apache sufficient privileges (and all uploaders also belong to this group and will have the same permissions), while safeguarding from "others" writing to this folder. Uploaded files Permission: 664 Owner: user:webserver Explanation: after uploading Apache might need to delete files, but this is no problem because they have w+r permission of the folder. So no need to make this file any more accessible than r access for group. Being not an expert on file permissions, my question is whether or not this is the best possible policy for our situation? Any suggestions welcome.

• How to use LVM on Rackspace Cloud

  - by batrick

  Dear all, I am trying to set up a simple but effective solution to make a backup of my rackspace cloud servers. These servers each run subversion, trac, and some database-backed custom php applications. My idea is to set up a LVM and mount a volume under, say, /srv. In this volume, I keep the data from all applications. Instead of caring about how to back-up each app in a different way (svn hotcopy, trac-admin hotcopy, huge mess for mysql), I simply take an LVM snapshot and back this one up cloud files using the excellent cloudcity script (http://github.com/jspringman/cloudcity/blob/master/cloudcity). The advantage of this solution is that it is quick and easy, and LVM allows to make decent backups. As more apps are added, it should not be required to change the backup script much. The downside, and main point of my question here, is that I am not sure how to get LVM working on Rackspace cloud, because there is only one root volume and no service like Amazon's EBS. I was thinking it may be possible to create a large empty file and use this as a "physical volume". Has anybody done anything like this before? Or do you know why it can never work? It would be great to hear from you. Thanks, batrick

• How to resume XMPP groupchat window in Irssi (using bitlbee)?

  - by mcnesium

  I use Bitlbee to chat in XMPP-networks within my IRC-client Irssi. This works great so far, and recently I started using XMPP Multi User Chats as an alternative to IRC-channels. I set up a channel using chat add <account> <[email protected]> in the &bitlbee control window, set chan <room> set autojoin true and entered /join #room in the &bitlbee window to join that groupchat. It then appears as a unique Irssi window in the status bar. This seems to work ok too, but with one exception: Since I idle in the channels 24/7 my irssi has to cope with the every-night-24h-DSL-disconnection by the ISP. After it automatically reconnects, it does kind of rejoin that XMPP-groupchat, but the traffic of the groupchat does not go back to the unique irssi window, but keeps flooding &bitlbee with messages from root telling me about a Groupchat Message from unknown JID <jid>: <message> - which is the traffic of the groupchat. The unique groupchat window is gone after the reconnect, and I will again have to go /join #room in &bitlbee to get it back. Even worse, the window number is unused before I rejoin the groupchat, and if I get a query from any network, the window nests in that unused window spot, so I will first have to remove that query from the spot, and then move the rejoined groupchat to that window number. I want my groupchat window to resume after the reconnect just like every other IRC channel too. How can I get this done? Any ideas?

• Sudo won't execute command as another user

  - by TOdorus

  I'm trying to get a unicorn server to start when the server boots. I've created a shell script which works if I log as the ubuntu user and run /etc/init.d/unicorn start Shell script #!/bin/sh case "$1" in start) cd /home/ubuntu/projects/asbest/current/ unicorn_rails -c /home/ubuntu/projects/asbest/current/config/unicorn.rb -D -E production ;; stop) if ps aux | awk '{print $2 }' | grep `cat ~/projects/asbest/current/tmp/pids/unicorn.pid`> /dev/null; then kill `cat ~/projects/asbest/current/tmp/pids/uni$ ;; restart) $0 stop $0 start ;; esac When I rebooted the server I noticed that the unicorn server wasn't listening to a socket. Since I ran the code succesfully as the ubuntu user I modified the script to let it always use the ubuntu user via sudo. #!/bin/sh case "$1" in start) cd /home/ubuntu/projects/asbest/current/ sudo -u ubuntu unicorn_rails -c /home/ubuntu/projects/asbest/current/config/unicorn.rb -D -E production ;; stop) if ps aux | awk '{print $2 }' | grep `cat ~/projects/asbest/current/tmp/pids/unicorn.pid`> /dev/null; then sudo -u ubuntu kill `cat ~/projects/asbest/current/tmp/pids/uni$ ;; restart) $0 stop $0 start ;; esac After rebooting unicorn still wouldn't start, so I tried running the script from the command line. Now I get the following error sudo: unicorn_rails: command not found I've searched high and low to what could cause this, but I'm afraid I've tapped my limited understanding of Linux. From what I can understand is that although sudo should use the ubuntu user to execute the commands, it still uses the environment of the root user, which isn't configured to run ruby or unicorn. Does anybody have any experience with this?

• Are my web server permissions for uploading correct?

  - by user1699176

  I'm on debian and I have my website in the directory /srv/www/mysite.com/public_html I set chown for www-data:www-data on /srv/www. I have root disabled and created a sudo user which is id 1000:1000. I would also like to use this user to upload to /srv/www so I added my sudo user to the www-data group. I originally got a message saying that I didn't have permissions to upload a file to that directory. After playing around with multiple permissions for a while I finally was able to upload properly, but I'm not sure if this set up is correct. I'm hesitant to change it for now since it actually works, so I thought I'd ask for advice. I think what I ended up doing was this: sudo chown -R www-data:www-data /srv/www sudo chmod g+s /srv/www sudo usermod -aG www-data myuser sudo chgrp -R www-data /srv/www sudo chmod -R g+w /srv/www When I was finally able to successfully upload a file (with FileZilla) it showed the owner as myuser myuser. Shouldn't it have been www-data myuser? My question is whether this is correct and if there are any potential security issues? For example, I wasn't sure if I was actually supposed to use "myuser" to own the /srv/www directory instead sudo chown -R myuser:myuser /srv/www or maybe sudo chown -R www-data:myuser /srv/www If you need more info, let me know, thanks.

• Mail Server using Postfix

  - by unknown (google)

  I have currently set up my web application on Amazon EC2 server. As a well known fact sending email from EC2 has a problem. As a cheap and long lasting solution instead of using "authsmtp" is it possible to rent a server and use it as a Mail Server? I am currently looking for cheap hosting which will give me root access so that it can be configured and used as a relayhost. I am curently using Postfix as MTA. Has any one implemented this before? I am curious about its feasibility of this solution. I guess common requirements are: 1: Dedicated IP which is not black listed. 2: Open relay( open to my Server only) Any Tips for Header configurations to keep the mails out of spam folder. This is like exactly cloning authsmtp for personal use. Any suggestions for other Mail Server software instead of Postfix? Another problem is Reverse DNS for this server. Should PTR entry be present if a server is used as a relayhost?

• Using an environment variable set to a path value: the system cannot find the path specified for %OPENCV_DIR%

  - by dumbledad

  I'm trying to set an environment variable to point to the directory into which I have extracted the latest version of OpenCV, following the instructions in OpenCV's Installation in Windows tutorial. Here's my elevated command line listing. C:\>cd C:\OpenCV2.4.6\build\x64\vc11 C:\OpenCV2.4.6\build\x64\vc11>cd ../../../.. C:\>setx -m OPENCV_DIR C:\OpenCV2.4.6\build\x64\vc11 SUCCESS: Specified value was saved. C:\>cd %OPENCV_DIR% The system cannot find the path specified. C:\>echo %OPENCV_DIR% %OPENCV_DIR% Firstly I change directory to C:\OpenCV2.4.6\build\x64\vc11 to ensure that it exists. After that is successful I change directory back to the root of the C drive. Then I use setx to make OPENCV_DIR a system wide environment variable with value the C:\OpenCV2.4.6\build\x64\vc11 path I verified in step 1. Noting the success of setx in the previous step I now change directory using the new environment variable. But it fails with the message The system cannot find the path specified. If I try to echo the value of the OPENCV_DIR environment variable it appears not to be set. Looking in the control panel the OPENCV_DIR environment variable looks correctly set: What's wrong? Why is the variable not working? Am I evoking it incorrectly when I use it to change directory or echo its value?

• SSH hangs when executing command remotely

  - by Serty Oan

  Client : OpenSSH_5.1p1 Debian-5ubuntu1 (Ubuntu 9.04) Server : OpenSSH_5.1p1 Debian-5 (Proxmox 2.6.24-7-pve) I use SSH to execute commands remotely on the server (module check_by_ssh of Nagios). But SSH hangs from time to time when trying to execute commands. I can log to the server via SSH but not executing a simple 'ls'. And it seems to block from all clients from the same IP address. Authentication is not the problem, may it be made by SSH keys or password. ssh -l root -p 2222 server.domain.tld 'ls' Here the client debug info debug1: Entering interactive session. debug2: callback start debug2: client_session2_setup: id 0 debug1: Sending environment. debug3: Ignored env ORBIT_SOCKETDIR *** skipping approx 40 env var ignored debug1: Sending command: ls debug2: channel 0: request exec confirm 1 It hangs there. Then after a random time, it works again (without doing anything). Killing all sshd process on the server seems to work too. It works from a Putty. I saw that some people had trouble like this due to ISP reverse DNS problem, but it does not seem to be the case here. It can work for hours and then not work for half an hour or so. What could explain this behaviour ?

• DNS redirecting to Apache

• Oracle Linux screen freezes during installation

  - by Fearless

  I was installing Oracle Linux 6.4 on a server, and the screen suddenly froze. Here were the previous steps: I put in the disk, clicked install, checked the disk (no errors), did pre-install setup (clock, root password, host+domain name, etc.), configured two 40GB hard drives in a RAID1 array (no swap, 3100mb encrypted raid partitions, ~100mb ext4 partition mounting to /boot, encrypted ext4 RAID device with mounting to /), selected packages, hit continue. The system did its short preinstall processes, then when to the main installation screen with the long status bar. The installer proceeded like always, but around package 250 out of ~1000, the screen suddenly went black with a text cursor in the upper left corner of the screen and the mouse cursor in its previous place. Neither cursor moved and the only thing that triggered a response was a ctrl-alt-delete that rebooted it. I have run this in VMs before without this issue. Memtest hasn't reported anything, and the media check went smoothly. The machine has supported Ubuntu server without issues before. Any ideas? I have tried booting after that, but the grub bootloader tries to find fd0 for some reason (I have no idea why it would search for the floppy disk). UPDATE My server successfully installed, but won't boot up. I think that, for some reason, it is still using the old bootloader from the previous installation. Any ideas on how to fix that?

Also, within ifdef's, arguments # containing commas must be quoted. # *.err;kern.notice;auth.notice /dev/sysmsg *.err;kern.debug;daemon.notice;mail.crit /var/adm/messages *.alert;kern.err;daemon.err operator *.alert root *.emerg * # if a non-loghost machine chooses to have authentication messages # sent to the loghost machine, un-comment out the following line: #auth.notice ifdef(`LOGHOST', /var/log/authlog, @loghost) mail.debug ifdef(`LOGHOST', /var/log/syslog, @loghost) # # non-loghost machines will use the following lines to cause "user" # log messages to be logged locally. # ifdef(`LOGHOST', , user.err /dev/sysmsg user.err /var/adm/messages user.alert `root, operator' user.emerg * ) Very interesting. when shutting down,, alerts go to all users probably through *.emerg * Looking at ifdef, it seems that the first parameter checks to see if current machine is a loghost, second parameter is what to do if it is and third parameter is what to do if it is not. Edit: If you want to test a logging rule you can use svcadm restart system-log to restart the logging service and then logger -p notice "test" to send a test log message where notice can be replaced with any type such as user.err, auth.notice, etc.

• Config nginx for slow connection to avoide corrupted doanlowds

  - by user1850273

  We have a Windows 2003 server that nginx 1.3.8 is running. Our problem is users with slow connction about 10K . Our server is serving our program update files and when they download from our server the downloade file is incompleted or crrupted. (Users can not download file with DL manager and the problem is in IE ) for example in slow connection a file with 25mb , after 2Mb downloaded finish . in high speed connections there is no problem. Also when we redirect these slow connection to other port F.e 50005 with the same config they download will be much better but not good as other servers. Which config we must apply to avoide such these download stops or corrupted downloads in slow connection ? this is our server config : worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent ' '"$http_user_agent"'; access_log logs/access.log main; sendfile off; keepalive_timeout 60; server { listen 80; server_name localhost; location / { root html; deny 127.0.0.3; index index.html index.htm; } } server_tokens off; } Our server use Htaccess password accounting and we can not use IIS on windows , Which soloution you think is better ? IIS with a extention to use apache htaccess ? Or use apache for windows insted of nginx ? Thank You.

• How do I install Apache Portable Runtime?

  - by apache

  My Apache is installed by yum install apache And now I'm trying to install subversion server from source following instructions here. But when I try to configure,get an error: [root@vps303 subversion-1.6.9]# ./configure configure: Configuring Subversion 1.6.9 configure: creating config.nice checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes ... checking for APR... no configure: WARNING: APR not found The Apache Portable Runtime (APR) library cannot be found. Please install APR on this system and supply the appropriate --with-apr option to 'configure' or get it with SVN and put it in a subdirectory of this source: svn co \ http://svn.apache.org/repos/asf/apr/apr/branches/1.2.x \ apr Run that right here in the top level of the Subversion tree. Afterwards, run apr/buildconf in that subdirectory and then run configure again here. Whichever of the above you do, you probably need to do something similar for apr-util, either providing both --with-apr and --with-apr-util to 'configure', or getting both from SVN with: svn co \ http://svn.apache.org/repos/asf/apr/apr-util/branches/1.2.x \ apr-util configure: error: no suitable apr found How do I get around this problem? BTW,will both client and server software be installed by compiling from source?

• How to make my Ubuntu an internet gateway for my Android phone

  - by yacine

  I want to use the internet of my school on my Android, the problem is they have a Squid proxy, and many applications on my phone don't use the proxy at all. The obvious solution is to install a transparent proxy on my Android to force all applications to connect through it. The problem is that I need to root the phone to make it work, and I don't want to do it because it's not really my phone and rooting is a little risky- Another solution, which is safer, is to make my computer run as a gateway, so I put my Ubuntu IP in the gateway parameter of the phone. I'm running a small proxy on my ubuntu (cntlm), so I redirect the Android traffic to it. I did it with "iptables" as follows: iptables -t nat -A PREROUTING -s 10.0.1.118 -p tcp -j REDIRECT --to-ports 8888 iptables -t nat -A PREROUTING -s 10.0.1.118 -p udp -j REDIRECT --to-ports 8888 10.0.1.118 is the IP of the phone, 8888 is the port of cntlm (proxy on my PC). Now, on the phone: When I enter www.google.com on the navigator I get nothing (web site not found, error message of Firefox). But, when I enter http://74.125.143.101 (IP of Google) I get an error message from the school proxy (so it worked in some way – my PC redirected the traffic of the phone to the Squid proxy). The error message is : The requested URL could not be retrieved while trying to process the request get / http/1.1 host 74.125.143.101 user-Agent ... ... I think the problem is in the "GET" header,it should be GET 74.125.143.101 HTTP/1.1. But I don't understand what's happening, and I'm a certified CCNA.
