• fail2ban with Cloudflare

  - by tatersalad58

  I'm using fail2ban to block web vulnerability scanners. It is working correctly when visiting the site if CloudFlare is bypassed, but a user can still access it if going through it. I have mod_cloudflare installed. Is it possible to block users with IPtables when using Cloudflare?

• Running complete Native Linux on phones that are bootloader-unlocked [on hold]

  - by james

  Since there are many phones (HTC, Samsung, LG, Nexus) today that have bootloader unlocked, I want to ask what's preventing them from running a complete native GNU/Linux. GNU/Linux has ARM port and we can run a command line GNU/Linux on top of Android by the method of chroot. So, what's preventing for existing bootloader unlocked Android phones from running a complete GNU/Linux natively? The device should get a long shelf life if it has one such port. My few thoughts.. Proprietary drivers for hardware that cannot be made to work when using a different OS. And the binary provider will never support any OS other than what the phone is shipped with. Application Interface. The interface for desktop apps doesn't fit to the mobile display with different PPI. Kernel. Since android devices use Linux kernel whose sources should be available, could the device kernel be modified to work with GNU/Linux. And any other reasons?

• Fix a tomcat6 error message "/bin/bash already running" when starting tomcat?

  - by Andrew Austin

  I have a Ubuntu 10.04 machine that has tomcat6 on it. When I start tomcat6 with /etc/init.d/tomcat6 start I get * Starting Tomcat servlet engine tomcat6 /bin/bash already running. and the server fails to start. Unfortunately, there is nothing in /var/log/tomcat/catalina.out to help debug the issue. With some cleverly placed echo statements it seems to be the line from /etc/init.d/tomcat6: start-stop-daemon --start -u "$TOMCAT6_USER" -g "$TOMCAT6_GROUP" \ -c "$TOMCAT6_USER" -d "$CATALINA_TMPDIR" \ -x /bin/bash -- -c "$AUTHBIND_COMMAND $TOMCAT_SH" The only thing I've changed in this script is TOMCAT6_USER=root. In servers.xml, the only thing I've changed is <Connector port="80" protocol="HTTP/1.1" from port 8080. I have tried reinstalling the package by first removing everything sudo apt-get --purge remove tomacat6 and then sudo apt-get install tomcat6 but this has not solved the issue. I have also restarted the server multiple times in hopes of some magic. Everything was working until I restarted my server. Any ideas?

• vncserver too many security failures

  - by cf16

  I try to connect to my vncserver running on CentOs from home computer, behind firewall. I have installed Win7 and Ubuntu both on this machine. I have an error: VNC conenction failed: vncserver too many security failures even when loging with right credentials (I reset passwd on CentOs). Is it something regarding that I try as root? I think important is also that I have to login to remote Centos through port 6050 - none else port works for me. Do I have to do something with other ports? I see that vncserver is listening on 5901, 5902 if another added - and I consider connection is established because from time to time (long time) the passwd prompt appears,... right? please help, what to do? even if prompt appeared and I put correct password I get: authentication failure. how to disable this lockout for a testing purposes?

• Cannot see http (apache) server outside home network

  - by user165155

  Ive been racking my brain with this all evening. Power went out with a tstorm today, started back up my server... running apache and a team speak server on it. TS is great, cant see my web page outside my network! Firewall is disabled on the pc running it (centos btw), apache is running and working. correct ports are forwarded on my router (my isp blocks port 80). Ive tried changing ports, pretty much everything i can think of. httpd.conf is pointing to the correct addy and port, and my domain is pointing to the correct external ip. Im at a loss, any ideas out there?

• freebsd does not recognise that php was installed via ports

  - by Alistair Prestidge

  I have php 5.2.12 installed on FreeBSD 8.0-STABLE. It was installed from ports and I am trying to upgrade it to 5.3.2. However for some reason my system is not recognising that php was installed via ports. When I run "pkg_version" the list does not include php it does however include all the extensions that I have installed. I have even tried to do "make deinstall" on "/usr/ports/lang/php5" it told me that the port had been deinstalled but php still appears to be working correctly i.e "php -v" works any ideas on how this port has become de attached from the ports system? and how I can get the ports system to recognise that it installed php?

• iptables dos limit for all ports

  - by user973917

  I know how to use limit conntrack option to allow for DoS protection. However, I want to add a protection to limit no more than say 50 connections for each port. How can I do this? Basically, I want to make sure that each port can have no more than 50 connections, rather than globally applying 50 connections (which is what #2 does I believe?) Would I do something like: iptables -A INPUT --dport 1:65535 -m limit --limit 50/minute --limit-burst 50 -j ACCEPT or iptables -A INPUT -m limit --limit 50/minute --limit-burst 50 -j ACCEPT

• Use netcat as a proxy to log traffic

  - by deephacks

  I want to use netcat as a proxy to log http requests and responses to files, then tail these to inspect traffic. Think wireshark. Tried the following where 'fifo' is a named pipe, 'in' and 'out' are files, netcat proxy on port 8080, server on port 8081. while true; do cat fifo | nc -l -p 8080 | tee -a in | nc localhost 8081 | tee -a out 1fifo; done Problems: Netcat stop responing after first request (while loop ignored?). Netcat fails with msg localhost [127.0.0.1] 8081 (tproxy) : Connection refused if server unavailable on 8081. Question: Is it possible to "lazily" connect to 8081 when request is made? I.e. I do not want to have 8081 running when netcat is started.

• iptables to play nice with tor and ntpd

  - by directedition

  I'm setting up a server to operate as a tor relay and nothing else. I setup iptables to only allow talk on port 9001 and it worked fine, but there was an issue, the clock needs to be properly set and maintained for the relay to work properly, so I needed ntpd setup and running, but for some reason I can't get iptables to work as I want it. I'm trying to have it allow only tor and ntpd to talk over the network, but when I set it up to allow port 123 using udp, suddenly it ignores my -A OUTPUT ! -s 127.0.0.1 -j DROP and allows everything through. How should I go about this? Please excuse my ignorance, I've brand new to iptables.

• add printer on windows 7 with vbscript and wmi

  - by Jessica

  I have a problem where I can't add a printer on my Windows 7 machine, because it fails with "The printer driver is unknown" (error code 1797) using WMI/VBScript. The thing is that the printer driver already exists on the PC. I've used AddPrinterConnection to connect to the remote printer queue, and the drivers get installed. I've confirmed they exist by a) Enumerating Win32_PrinterDriver with WBEMTEST utility which shows the driver, and also in the Printer Management MMC snap-in. Is there some other scriptable way I can get this to work? I'm adding a local TCP/IP port, pointing my new printer object instance to use that port and the driver from using AddPrinterConnection, and giving it a name, but it refuses to work...

• Two Tomcat SSL Providers & One FreeBSD

  - by mosg

  Hello everyone. Question: On FreeBSD8 I need to have two opened HTTPS different ports (443 and 444, for example). In other words, I need two providers, working simultaneously: Ordinary SSL signed certificate (# Thawte) on 443 port Special russian security provider (# DIGTProvider, based on CryptoPro CSP software) on 444 port I also have to mentioned, that the major provider is the 2'nd provider. Here is some of DIGTProvider options: add to ${JRE_HOME}/lib/security/java.security this line security.provider.N=com.digt.trusted.jce.provider.DIGTProvider ssl.SocketFactory.provider=com.digt.trusted.jsse.provider.DigtSocketFactory uncomment and edit in conf/server.xml HTTPS section: sslProtocol="GostTLS" (added) edit bin/catalina.sh and add: export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/opt/cprocsp/lib/ia32" export JAVA_OPTS="${JAVA_OPTS} -Dcom.digt.trusted.jsse.server.certFile=/home//server-gost.cer -Dcom.digt.trusted.jsse.server.keyPasswd=11111111" As I know if I just define in server.xml tomcat's configuration file two SSL connectors, tomcat would not start, because in JRE you can use only one JSSE provider. Thanks for help.

• Tomcat with virtual hosts - 404

  - by Thardas

  I have a CentOS 5.2 server set up with Apache 2.2.3 and Tomcat 5.5.27. The server hosts multiple virtual hosts connected to multiple Tomcats. For instance we have one tomcat for development and testing and one tomcat for production. project.demo.us.com points to dev tomcat and project.us.com points to production tomcat. Here's the virtual host's configuration: <VirtualHost *:80> ServerName project.demo.us.com CustomLog logs/project.demo.us.com/access_log combined env=!VLOG ErrorLog logs/project.demo.us.com/error_log DocumentRoot /var/www/vhosts/project.demo.us.com <Directory /var/www/vhosts/project.demo.us.com> Allow from all AllowOverride All Options -Indexes FollowSymLinks </Directory> ########## ########## ########## JkMount /project/* online </VirtualHost> JkMount line defines that we use online worker and our workers.properties contains this: worker.list=..., online, ... worker.online.port=7703 worker.online.host=localhost worker.online.type=ajp13 worker.online.lbfactor=1 And tomcat's conf/server.xml contains: <Connector port="7703" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" URIEncoding="UTF-8" maxThreads="80" minSpareThreads="10" maxSpareThreads="15"/> I'm not sure what redirectPort is but I tried to telnet to that port and there's no one answering, so it shouldn't matter? Tomcat's webapps directory contains project.war and the server automatically deployed it under project directory which contains index.jsp and hello.html. The latter is for static debugging purposes. Now when I try to access http://project.demo.us.com/project/index.jsp, I get Tomcat's HTTP Status 404 - The requested resource () is not available. The same thing happens to hello.html so it's not working with static content either. Apache's access_log contains: 88.112.152.31 - - [10/Aug/2009:12:15:14 +0300] "GET /demo/index.jsp HTTP/1.1" 404 952 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2" I couldn't find any mention of the request in Tomcat's logs. If I shutdown this specific tomcat, I no longer get Tomcat's 404 but Apache's 503 Service Temporarily Unavailable, so I should be configuring the correct Tomcat. Is there something obvious that I'm missing? Is there any place where I could find out what path the Tomcat is using to look for requested files?

• HP MSR 30-10a Router - Route Traffic over Default Route

  - by SteadH

  We have a brand new HP MSR 30-10a Router. We have a fairly simple routing situation - we have two IP blocks, one which has a route out. We need things on the first block to go through the router, and out. I have an old Cisco 2801 router doing the job right now. For our example - IP Block 1: 50.203.110.232/29, Router interface on this block is 50.203.110.237, route out is 50.203.110.233. IP Block 2: 50.202.219.1/27, Router interface on this block at 50.202.219.20. I have a static route created for: 0.0.0.0 0.0.0.0 50.203.110.233 The router seems to understand this. When on the CLI via serial cable, I can ping 8.8.8.8 and hear responses from Google DNS. Woo hoo! The issue arrives when any client sits on the IP Block 2 side. I configured my client with a static IP of 50.202.219.15/27, default gateway 50.202.219.20. I can ping myself. I can ping the near side of the router (50.202.219.20), and I can ping the far side of the router (50.203.110.237. I cannot ping anything else in IP block 1, nor can I ping 8.8.8.8. Here is my configuration file: <HP>display current-configuration # version 5.20.106, Release 2507, Standard # sysname HP # domain default enable system # dar p2p signature-file flash:/p2p_default.mtd # port-security enable # undo ip http enable # password-recovery enable # vlan 1 # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user admin password cipher $c$3$40gC1cxf/wIJNa1ufFPJsjKAof+QP5aV authorization-attribute level 3 service-type telnet # cwmp undo cwmp enable # interface Aux0 async mode flow link-protocol ppp # interface Cellular0/0 async mode protocol link-protocol ppp # interface Ethernet0/0 port link-mode route ip address 50.203.110.237 255.255.255.248 # interface Ethernet0/1 port link-mode route ip address 50.202.219.20 255.255.255.224 # interface NULL0 # ip route-static 0.0.0.0 0.0.0.0 50.203.110.233 permanent # load xml-configuration # load tr069-configuration # user-interface tty 12 user-interface aux 0 user-interface vty 0 4 authentication-mode scheme # My guess right now is there is some sort of "permission" needed to use the default route. The manuals haven't turned up a lot in this area that don't make the situation much more complicated (but maybe it needs to be more complicated?) Background: we use HP switches, and I love the CLI. I bought HP thinking the command line interface would be similar, or at least speak the same language. Whoops! I'd be happy to provide more information or perform any additional tests. Thanks in advance! Update 1: The manual mentions routing rules. I hadn't previously added these (since our Cisco 2801 seems to route anything by default). I added: ip ip-prefix 1 permit 0.0.0.0 0 less-equal 32 alas, still no dice.

• php-fpm + persistent sockets = 502 bad gateway

  - by leeoniya

  Put on your reading glasses - this will be a long-ish one. First, what I'm doing. I'm building a web-app interface for some particularly slow tcp devices. Opening a socket to them takes 200ms and an fwrite/fread cycle takes another 300ms. To reduce the need for both of these actions on each request, I'm opening a persistent tcp socket which reduces the response time by the aforementioned 200ms. I was hoping PHP-FPM would share the persistent connections between requests from different clients (and indeed it does!), but there are some issues which I havent been able to resolve after 2 days of interneting, reading logs and modifying settings. I have somewhat narrowed it down though. Setup: Ubuntu 13.04 x64 Server (fully updated) on Linode PHP 5.5.0-6~raring+1 (fpm-fcgi) nginx/1.5.2 Relevent config: nginx worker_processes 4; php-fpm/pool.d pm = dynamic pm.max_children = 2 pm.start_servers = 2 pm.min_spare_servers = 2 Let's go from coarse to fine detail of what happens. After a fresh start I have 4x nginx processes and 2x php5-fpm processes waiting to handle requests. Then I send requests every couple seconds to the script. The first take a while to open the socket connection and returns with the data in about 500ms, the second returns data in 300ms (yay it's re-using the socket), the third also succeeds in about 300ms, the fourth request = 502 Bad Gateway, same with the 5th. Sixth request once again returns data, except now it took 500ms again. The process repeats for several cycles after which every 4 requests result in 2x 502 Bad Gateways and 2x 500ms Data responses. If I double all the fpm pool values and have 4x php-fpm processes running, the cycles settles in with 4x successful 500ms responses followed by 4x Bad Gateway errors. If I don't use persistent sockets, this issue goes away but then every request is 500ms. What I suspect is happening is the persistent socket keeps each php-fpm process from idling and ties it up, so the next one gets chosen until none are left and as they error out, maybe they are restarted and become available on the next round-robin loop ut the socket dies with the process. I haven't yet checked the 'slowlog', but the nginx error log shows lots of this: *188 recv() failed (104: Connection reset by peer) while reading response header from upstream, client:... All the suggestions on the internet regarding fixing nginx/php-fpm/502 bad gateway relate to high load or fcgi_pass misconfiguration. This is not the case here. Increasing buffers/sizes, changing timeouts, switching from unix socket to tcp socket for fcgi_pass, upping connection limits on the system....none of this stuff applies here. I've had some other success with setting pm = ondemand rather than dynamic, but as soon as the initial fpm-process gets killed off after idling, the persistent socket is gone for all subsequent php-fpm spawns. For the php script, I'm using stream_socket_client() with a STREAM_CLIENT_PERSISTENT flag. A while/stream_select() loop to detect socket data and fread($sock, 4096) to grab the data. I don't call fclose() obviously. If anyone has some additional questions or advice on how to get a persistent socket without tying up the php-fpm processes beyond the request completion, or maybe some other things to try, I'd appreciate it. some useful links: Nginx + php-fpm - recv() error Nginx + php-fpm "504 Gateway Time-out" error with almost zero load (on a test-server) Nginx + PHP-FPM "error 104 Connection reset by peer" causes occasional duplicate posts http://www.linuxquestions.org/questions/programming-9/php-pfsockopen-552084/ http://stackoverflow.com/questions/14268018/concurrent-use-of-a-persistent-php-socket http://devzone.zend.com/303/extension-writing-part-i-introduction-to-php-and-zend/#Heading3 http://stackoverflow.com/questions/242316/how-to-keep-a-php-stream-socket-alive http://php.net/manual/en/install.fpm.configuration.php https://www.google.com/search?q=recv%28%29+failed+%28104:+Connection+reset+by+peer%29+while+reading+response+header+from+upstream+%22502%22&ei=mC1XUrm7F4WQyAHbv4H4AQ&start=10&sa=N&biw=1920&bih=953&dpr=1

• How can I stop my laptop display from flickering when I connect my TV?

  - by Lord Torgamus

  I have a laptop with an HDMI output port running Vista, and an HDTV with HDMI input ports. The laptop is set to extend its desktop onto a second monitor. When I connect the computer to the TV with an HDMI cable, my laptop screen usually flickers rapidly. Most of the time it lasts for about 30 seconds, but sometimes it lasts for several minutes and once in a while it doesn't happen at all. It wouldn't be so bad except that the cursor moves back to the center of the laptop screen with each flicker, so I can't really do anything until the machine decides it's ready to calm down. I haven't been able to find any pattern at all for the causes or duration of the flickering. It doesn't seem to matter what programs the laptop is running when I connect it to the TV, whether I enable the extended display before or after I connect the TV or which HDMI port/cable I use. What could be causing this, and how can I make it go away?

• Firebox Edge 11 and SBS 2008 VPN produces error 721

  - by Charlie Bear

  My VPN has stopped working. I have sbs 2008 and have run the VPN wizard. I have opened the port 1723 on my firebox edge as it instructed me to do. It was working but I think that an upgrade of the firebox software to version 11 has affected it. The port is still open. When connecting I get to verifying username and password then I get Error 721. Not sure whats wrong here. can anyone help?
