• Cisco ASA 5505 site to site IPSEC VPN won't route from multiple LANs

  - by franklundy

  Hi I've set up a standard site to site VPN between 2 ASA 5505s (using the wizard in ASDM) and have the VPN working fine for traffic between Site A and Site B on the directly connected LANs. But this VPN is actually to be used for data originating on LAN subnets that are one hop away from the directly connected LANs. So actually there is another router connected to each ASA (LAN side) that then route to two completely different LAN ranges, where the clients and servers reside. At the moment, any traffic that gets to the ASA that has not originated from the directly connected LAN gets sent straight to the default gateway, and not through the VPN. I've tried adding the additional subnets to the "Protected Networks" on the VPN, but that has no effect. I have also tried adding a static route to each ASA trying to point the traffic to the other side, but again this hasn't worked. Here is the config for one of the sites. This works for traffic to/from the 192.168.144.x subnets perfectly. What I need is to be able to route traffic from 10.1.0.0/24 to 10.2.0.0/24 for example.

• Nginx + PHP-FPM = "Random" 502 Bad Gateway

  - by david

  I am running Nginx and proxying php requests via FastCGI to PHP-FPM for processing. I will randomly receive 502 Bad Gateway error pages - I can reproduce this issue by clicking around my PHP websites very rapidly/refreshing a page for a minute or two. When I get the 502 error page all I have to do is refresh the browser and the page refreshes properly. Here is my setup: nginx/0.7.64 PHP 5.3.2 (fpm-fcgi) (built: Apr 1 2010 06:42:04) Ubuntu 9.10 (Latest 2.6 Paravirt) I compiled PHP-FPM using this ./configure directive ./configure --enable-fpm --sysconfdir=/etc/php5/conf.d --with-config-file-path=/etc/php5/conf.d/php.ini --with-zlib --with-openssl --enable-zip --enable-exif --enable-ftp --enable-mbstring --enable-mbregex --enable-soap --enable-sockets --disable-cgi --with-curl --with-curlwrappers --with-gd --with-mcrypt --enable-memcache --with-mhash --with-jpeg-dir=/usr/local/lib --with-mysql=/usr/bin/mysql --with-mysqli=/usr/bin/mysql_config --enable-pdo --with-pdo-mysql=/usr/bin/mysql --with-pdo-sqlite --with-pspell --with-snmp --with-sqlite --with-tidy --with-xmlrpc --with-xsl My php-fpm.conf looks like this (the relevant parts): ... <value name="pm"> <value name="max_children">3</value> ... <value name="request_terminate_timeout">60s</value> <value name="request_slowlog_timeout">30s</value> <value name="slowlog">/var/log/php-fpm.log.slow</value> <value name="rlimit_files">1024</value> <value name="rlimit_core">0</value> <value name="chroot"></value> <value name="chdir"></value> <value name="catch_workers_output">yes</value> <value name="max_requests">500</value> ... I've tried increasing the max_children to 10 and it makes no difference. I've also tried setting it to 'dynamic' and setting max_children to 50, and start_server to '5' without any difference. I have tried using both 1 and 5 nginx worker processes. My fastcgi_params conf looks like: fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REDIRECT_STATUS 200; Nginx logs the error as: [error] 3947#0: *10530 connect() failed (111: Connection refused) while connecting to upstream, client: 68.40.xxx.xxx, server: www.domain.com, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.domain.com" PHP-FPM logs the follow at the time of the error: [NOTICE] pid 17161, fpm_unix_init_main(), line 255: getrlimit(nofile): max:1024, cur:1024 [NOTICE] pid 17161, fpm_event_init_main(), line 93: libevent: using epoll [NOTICE] pid 17161, fpm_init(), line 50: fpm is running, pid 17161 [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17162 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17163 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17164 started [NOTICE] pid 17161, fpm_event_loop(), line 111: ready to handle connections My CPU usage maxes out around 10-15% when I recreate the issue. My Free mem (free -m) is 130MB I had this intermittent 502 Bad Gateway issue when in was using php5-cgi to service my php requests as well. Does anyone know how to fix this?

• Varnish cached 'MISS status' object?

  - by Hesey

  My site uses nginx, varnish, jboss. And some url will be cached by varnish, it depends a response header from jboss. The first time, jboss tells varnish doesn't cache this url. Then the second request, jboss tells varnish to cache, but varnish won't cache it. I used varnishstat and found that 1 object is cached in Varnish, is that the 'MISS status' object? I remove grace code and the problem still exists. When I PURGE this url, varnish works fine and cache the url then. But I can't PURGE so much urls every startup time, how can I fix this? The configuration: acl local { "localhost"; } backend default { .host = "localhost"; .port = "8080"; .probe = { .url = "/preload.htm"; .interval = 3s; .timeout = 1s; .window = 5; .threshold = 3; } } sub vcl_deliver { if (req.request == "PURGE") { remove resp.http.X-Varnish; remove resp.http.Via; remove resp.http.Age; remove resp.http.Content-Type; remove resp.http.Server; remove resp.http.Date; remove resp.http.Accept-Ranges; remove resp.http.Connection; set resp.http.keeplive="true"; } else { if (obj.hits > 0) { set resp.http.X-Cache = "HIT"; } else { set resp.http.X-Cache = "MISS"; } } } sub vcl_recv { if(req.url ~ "/check.htm"){ error 404 "N"; } if( req.http.host ~ "store." || req.request == "POST"){ return (pipe); } if (req.backend.healthy) { set req.grace = 30s; } else { set req.grace = 10m; } set req.http.x-cacheKey = "0"; if(req.url ~ "/shop/view_shop.htm" || req.url ~ "/shop/viewShop.htm" || req.url ~ "/index.htm"){ if(req.url ~ "search=y"){ set req.http.x-cacheKey = req.http.host + "/search.htm"; }else if(req.url !~ "bbs=y" && req.url !~ "shopIntro=y" && req.url !~ "shop_intro=y"){ set req.http.x-cacheKey = req.http.host + "/index.htm"; } }else if(req.url ~ "/search"){ set req.http.x-cacheKey = req.http.host + "/search.htm"; } if( req.http.x-cacheKey == "0" && req.url !~ "/i/"){ return (pipe); } if (req.request == "PURGE") { if (client.ip ~ local) { return (lookup); } else { error 405 "Not allowed."; } } if (req.url ~ "/i/") { set req.http.x-shop-url = req.original_url; }else { unset req.http.cookie; } } sub vcl_fetch { set beresp.grace = 10m; #unset beresp.http.x-cacheKey; if (req.url ~ "/i/" || req.url ~ "status" ){ set beresp.ttl = 0s; /* ttl=0 for dynamic content */ } else if(beresp.http.x-varnish-cache != "1"){ set beresp.do_esi = true; /* Do ESI processing */ set beresp.ttl = 0s; unset beresp.http.set-cookie; } else { set beresp.do_esi = true; /* Do ESI processing */ set beresp.ttl = 1800s; unset beresp.http.set-cookie; } } sub vcl_hash { hash_data(req.http.x-cacheKey); return (hash); } sub vcl_error { if (req.request == "PURGE") { return (deliver); } else { set obj.http.Content-Type = "text/html; charset=gbk"; synthetic {"<!--ve-->"}; return (deliver); } } sub vcl_hit { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged."; } } sub vcl_miss { if (req.request == "PURGE") { error 404 "N"; } }

  We are using PHP 5.3.6 here, but we used the --without-sqlite3 command when compiling PHP. (It stands in the 'Configure Command' column). But, it is very risky to recompile PHP on that server; there are many visitors. How can we install/use sqlite3?

• Securing smtp with login

  - by Paul Peelen

  I have a ispconfig server, and it seems that someone is using it to send spam. I got about 130 "Mail Delivery System" email about declined send email. This spammer uses my email address as sent from adress, so I get all these email adresses to my mail. I am using Postfix and Courier. I installed my server according to this guide: http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3-p3 I did this a few months ago.

• Multiple Homed Windows 2008 Server / Windows 7 Client

  - by Daniel Scott

  I have a small Windows 2008 network, with some Windows 7 clients. The clients are both laptops with docking stations and I would like them to communicate with the Windows 2008 server (for filesharing) through the wired network whilst they're docked. Internet connectivity for all machines (clients and server) is via a Wireless LAN, so the wireless adapter in the Windows 7 clients stays active while they're docked. When the laptops are un-docked, it would be nice to still be able to contact the windows 2008 server for print sharing (and slower file sharing) - hence the server also being on the wireless LAN. The windows 2008 server is running Active Directory, DHCP and DNS. It controls DHCP leases on the wired network and holds the DNS records for "myserver.mycompany.local", which is what the filesharing clients connect to. Ideally I'd like the DNS records to return the wired IP first so that this is the address that the laptops will attempt initially - but there doesn't seem to be a way to do that? At present the server's IP on the wireless LAN comes out of an nslookup above the wired Lan IP. The multi-homing works perfectly - but in the wrong order! Switch on the wireless lan and ping myserver and it goes to the wireless IP. Disable the wireless on the client and do the same ping again and after a couple of seconds it starts pinging the wired address. Does anyone have any suggestions on how to make this work in a predictable order? - or even if it can work. Alternative 1? If it can't work, then would this work: Remove the wireless adapter from the server, put a wireless router/bridge on the wired network (set up to route to/from the wireless LAN's subnet), then configure the clients with two routes to the (now) single IP of the server with metrics favouring direct communication over the wired LAN first? Alternative 2? Should I instead single-home the laptops so all of their connectivity is via the wired-LAN while they're docked? (and route via the windows 2008 server - or a dedicated wireless bridge/router)? My concern here is that I'd like undocking to be seamless - and if the clients are in the middle of downloading something from the internet I wouldn't want whatever they're doing interupted as they switch IP addresses onto the Wireless network. Perhaps this isn't the case and I'm concerned over nothing? Any thoughts? :) UPDATE I seem to have cracked it (at least DNS entries come out in the order I hope for - and pinging the server with various combinations of wired, wireless and both interfaces enabled uses the IP I want) ... I set the binding order of the NICs on the Server (which is acting as Domain Controller, DHCP and DNS server) so that the Wired NIC is before the Wireless adapter. (Start -- type "Network Interfaces" -- Select "View Network Connections" -- Press Alt to show classic dropdown menus -- Advanced -- Advanced Settings) Now, an nslookup (from the client) of the server's hostname returns the Wired IP first, followed by the Wireless IP. The wired IP now seems to be used whenever it's contactable. Incidentally, the metrics on the wired and wireless routes (on the client) also favour the wired LAN (based on Windows' automatically assigned metrics) - but this was always the case, even when I was having trouble getting the wired IP to be "favoured". I'm not entirely sure if this is coincidence - or if a DNS server running on Windows, handing back IP addresses for itself does actually take the binding order of it's own network interfaces into account? It would be interesting to hear from someone who can confirm or deny that (or confirm that the binding order on the server plays a role for some other reason?)

• Simple Cisco ASA 5505 config issue

  - by Ben Sebborn

  I have a Cisco ASA setup with two interfaces: inside: 192.168.2.254 / 255.255.255.0 SecLevel:100 outside: 192.168.3.250 / 255.255.255.0 SecLevel: 0 I have a static route setup to allow PCs on the inside network to access the internet via a gateway on the outside interface (3.254): outside 0.0.0.0 0.0.0.0 192.168.3.254 This all works fine. I now need to be able to access a PC on the outside interface (3.253) from a PC on the inside interface on port 35300. I understand I should be able to do this with no problems, as I'm going from a higher security level to a lower one. However I can't get any connection. Do I need to set up a seperate static route? Perhaps the route above is overriding what I need to be able to do (is it routing ALL traffic through the gateway?) Any advice on how to do this would be apprecaited. I am configuring this via ASDM but the config can be seen as below: Result of the command: "show running-config" : Saved : ASA Version 8.2(5) ! hostname ciscoasa domain-name xxx.internal names name 192.168.2.201 dev.xxx.internal description Internal Dev server name 192.168.2.200 Newserver ! interface Ethernet0/0 switchport access vlan 2 ! interface Ethernet0/1 ! interface Ethernet0/2 ! interface Ethernet0/3 shutdown ! interface Ethernet0/4 shutdown ! interface Ethernet0/5 shutdown ! interface Ethernet0/6 shutdown ! interface Ethernet0/7 shutdown ! interface Vlan1 nameif inside security-level 100 ip address 192.168.2.254 255.255.255.0 ! interface Vlan2 nameif outside security-level 0 ip address 192.168.3.250 255.255.255.0 ! ! time-range Workingtime periodic weekdays 9:00 to 18:00 ! ftp mode passive clock timezone GMT/BST 0 clock summer-time GMT/BDT recurring last Sun Mar 1:00 last Sun Oct 2:00 dns domain-lookup inside dns server-group DefaultDNS name-server Newserver domain-name xxx.internal same-security-traffic permit inter-interface object-group service Mysql tcp port-object eq 3306 object-group protocol TCPUDP protocol-object udp protocol-object tcp access-list inside_access_in extended permit ip any any access-list outside_access_in remark ENABLES OUTSDIE ACCESS TO DEV SERVER! access-list outside_access_in extended permit tcp any interface outside eq www time-range Workingtime inactive access-list outside_access_in extended permit tcp host www-1.xxx.com interface outside eq ssh access-list inside_access_in_1 extended permit tcp any any eq www access-list inside_access_in_1 extended permit tcp any any eq https access-list inside_access_in_1 remark Connect to SSH services access-list inside_access_in_1 extended permit tcp any any eq ssh access-list inside_access_in_1 remark Connect to mysql server access-list inside_access_in_1 extended permit tcp any host mysql.xxx.com object-group Mysql access-list inside_access_in_1 extended permit tcp any host mysql.xxx.com eq 3312 access-list inside_access_in_1 extended permit object-group TCPUDP host Newserver any eq domain access-list inside_access_in_1 extended permit icmp any any access-list inside_access_in_1 remark Draytek Admin access-list inside_access_in_1 extended permit tcp any 192.168.3.0 255.255.255.0 eq 4433 access-list inside_access_in_1 remark Phone System access-list inside_access_in_1 extended permit tcp any 192.168.3.0 255.255.255.0 eq 35300 log disable pager lines 24 logging enable logging asdm warnings logging from-address [email protected] logging recipient-address [email protected] level errors mtu inside 1500 mtu outside 1500 ip verify reverse-path interface inside ip verify reverse-path interface outside ipv6 access-list inside_access_ipv6_in permit tcp any any eq www ipv6 access-list inside_access_ipv6_in permit tcp any any eq https ipv6 access-list inside_access_ipv6_in permit tcp any any eq ssh ipv6 access-list inside_access_ipv6_in permit icmp6 any any icmp unreachable rate-limit 1 burst-size 1 icmp permit any outside no asdm history enable arp timeout 14400 global (outside) 1 interface nat (inside) 1 0.0.0.0 0.0.0.0 static (inside,outside) tcp interface www dev.xxx.internal www netmask 255.255.255.255 static (inside,outside) tcp interface ssh dev.xxx.internal ssh netmask 255.255.255.255 access-group inside_access_in in interface inside control-plane access-group inside_access_in_1 in interface inside access-group inside_access_ipv6_in in interface inside access-group outside_access_in in interface outside route outside 0.0.0.0 0.0.0.0 192.168.3.254 10 route outside 192.168.3.252 255.255.255.255 192.168.3.252 1 timeout xlate 3:00:00 timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02 timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00 timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00 timeout sip-provisional-media 0:02:00 uauth 0:05:00 absolute timeout tcp-proxy-reassembly 0:01:00 timeout floating-conn 0:00:00 dynamic-access-policy-record DfltAccessPolicy aaa authentication telnet console LOCAL aaa authentication enable console LOCAL

• apache webserver unresponsible with server-status showing all child processes waiting for connection

  - by Jeff

  My setup: i have 3 nearly identical webserver machines serving the same high loaded dynamic website with simple load balancing over dns. The service has been working for over two ears with the same apache config. apache2, php5, ubuntu 8.04 linux 2.6.24-29-server My problem: since about two weeks i'm experiencing problems with this config. Nearly every day i have one small moment about 5 minutes, in which the website is unreachable. I'm still able to login to the servers over ssh. If i run htop, i see the machine simply doing nothing. i have about 1000 apache processes running, but no cpu activity. i've used the apache mod_status to debug this situation. the process scoreboard looks like this: _C.___K_______________________R._______.__K_K____K___C_______.__ _______C__________.___________________________________.________C _.____K__________K___K_WK_____._K_____________________________._ W______K__________K________.____________________._______C_______ _C_.__K__K____.._.._____________________________________C_______ _R___________K___.______C________.C_________.______._____C______ ____________KKC____K_____K__WC_________________C_____.__.____.__ _____________________C_________K______.____C______._____________ _.___C____.___.___________________________.K______.____K________ W__.___________________C.__.____K________K_______R_._.__._______ __C__C_.__________C__C_______._____W______________C_.___C_______ ____.______C_____________C________.____C____________.________._K __.__________.K_____________K_________._____C____.K__________KW_ __K.W________R_________._______.___W___________.____.__K_____W__ W___.___..________W____K Scoreboard Key: "_" Waiting for Connection, "S" Starting up, "R" Reading Request, "W" Sending Reply, "K" Keepalive (read), "D" DNS Lookup, "C" Closing connection, "L" Logging, "G" Gracefully finishing, "I" Idle cleanup of worker, "." Open slot with no current process So the most of the processes are just waiting for connection. after about 5 minutes the situation will return to normal: i have lot least processes on every machine, the most workers have the "."-status (meaing they are open to process a request) and of course the website is reachable! so i'm trying to find something in the logs, but there is simply nothing... the apache access log is silent for about 4 minutes, the same is for the error log. i also can not figure out anything wrong in other system logs. the situation is the same on all 3 webservers (all of them have this load peak and unresposibility at the same time), so i do not thing this is hardware related. but i think, this might be related to some network (tcp) issue. any ideas? EDIT: some more information, that i have just discovered: it has just happened again. and i was able to verify that i'm also not able to connect locally when this problem occurs. i have made some connection statistics with the following command after it happend netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c 109 CLOSE_WAIT 2652 ESTABLISHED 2 FIN_WAIT1 11 LAST_ACK 12 LISTEN 91 SYN_RECV 1 SYN_SENT 16 TIME_WAIT If i execute the same command some time later, i have something like this: 4 CLOSING 108 ESTABLISHED 18 FIN_WAIT1 182 FIN_WAIT2 37 LAST_ACK 12 LISTEN 50 SYN_RECV 11276 TIME_WAIT So in the normal situation i have only 100-200 open connections by clients beeing handled by apache in this moment. when i have this "crash", i have a lot more connections. what is the best way to analyse this? EDIT2: the important lines in apache2.conf are: KeepAlive On MaxKeepAliveRequests 20 KeepAliveTimeout 1 <IfModule mpm_prefork_module> ServerLimit 920 StartServers 30 MinSpareServers 80 MaxSpareServers 120 MaxClients 920 MaxRequestsPerChild 700 </IfModule> it is an apache2 prefork with php_mod. the server has 8GB ram and a 4gb swap partition.

• udp through nat

  - by youllknow

  Hi everyone! I've two private networks (each of them behind a typical dsl router). The routers are connected to the WWW. The extern interface of each router have one dynamic IP address. I want to stream data via UDP directly between one client in private network A and one client in private network B. I've already tried a lot of things (see: http://en.wikipedia.org/wiki/UDP_hole_punching, or STUN). But it wasn't possible for me to transfer data between the two clients. It's possible to use a server (located in the WWW, with static IP) to transfer the extern IPs (and extern ports) from the routers between the clients. So imagine client A knows client B's external IP and client B's external port assigned by his router. I simply tried sending UDP packet to the receivers external IP/port combination, but without any result. So does anyone know what do to communicate via UDP throw the two NAT routers? It must be possible??? Or does Skype, for example, not directly communicate between the clients when the call eachother (voice over ip). I am sorry for my bad English! If something is confusing don't mind asking me!!! Thanks for your help in advance. ::::EDIT:::: I can't get pwnat or chownat working. I tried it with my own dsl-gateway - didn't work. Then I set up a complete virtual environment using VMWare.

• RHCS: GFS2 in A/A cluster with common storage. Configuring GFS with rgmanager

  - by Pavel A

  I'm configuring a two node A/A cluster with a common storage attached via iSCSI, which uses GFS2 on top of clustered LVM. So far I have prepared a simple configuration, but am not sure which is the right way to configure gfs resource. Here is the rm section of /etc/cluster/cluster.conf: <rm> <failoverdomains> <failoverdomain name="node1" nofailback="0" ordered="0" restricted="1"> <failoverdomainnode name="rhc-n1"/> </failoverdomain> <failoverdomain name="node2" nofailback="0" ordered="0" restricted="1"> <failoverdomainnode name="rhc-n2"/> </failoverdomain> </failoverdomains> <resources> <script file="/etc/init.d/clvm" name="clvmd"/> <clusterfs name="gfs" fstype="gfs2" mountpoint="/mnt/gfs" device="/dev/vg-cs/lv-gfs"/> </resources> <service name="shared-storage-inst1" autostart="0" domain="node1" exclusive="0" recovery="restart"> <script ref="clvmd"> <clusterfs ref="gfs"/> </script> </service> <service name="shared-storage-inst2" autostart="0" domain="node2" exclusive="0" recovery="restart"> <script ref="clvmd"> <clusterfs ref="gfs"/> </script> </service> </rm> This is what I mean: when using clusterfs resource agent to handle GFS partition, it is not unmounted by default (unless force_unmount option is given). This way when I issue clusvcadm -s shared-storage-inst1 clvm is stopped, but GFS is not unmounted, so a node cannot alter LVM structure on shared storage anymore, but can still access data. And even though a node can do it quite safely (dlm is still running), this seems to be rather inappropriate to me, since clustat reports that the service on a particular node is stopped. Moreover if I later try to stop cman on that node, it will find a dlm locking, produced by GFS, and fail to stop. I could have simply added force_unmount="1", but I would like to know what is the reason behind the default behavior. Why is it not unmounted? Most of the examples out there silently use force_unmount="0", some don't, but none of them give any clue on how the decision was made. Apart from that I have found sample configurations, where people manage GFS partitions with gfs2 init script - https://alteeve.ca/w/2-Node_Red_Hat_KVM_Cluster_Tutorial#Defining_The_Resources or even as simply as just enabling services such as clvm and gfs2 to start automatically at boot (http://pbraun.nethence.com/doc/filesystems/gfs2.html), like: chkconfig gfs2 on If I understand the latest approach correctly, such cluster only controls whether nodes are still alive and can fence errant ones, but such cluster has no control over the status of its resources. I have some experience with Pacemaker and I'm used to that all resources are controlled by a cluster and an action can be taken when not only there are connectivity issues, but any of the resources misbehave. So, which is the right way for me to go: leave GFS partition mounted (any reasons to do so?) set force_unmount="1". Won't this break anything? Why this is not the default? use script resource <script file="/etc/init.d/gfs2" name="gfs"/> to manage GFS partition. start it at boot and don't include in cluster.conf (any reasons to do so?) This may be a sort of question that cannot be answered unambiguously, so it would be also of much value for me if you shared your experience or expressed your thoughts on the issue. How does for example /etc/cluster/cluster.conf look like when configuring gfs with Conga or ccs (they are not available to me since for now I have to use Ubuntu for the cluster)? Thanks you very much!

• Inconsistent file downloads of (what should be) the same file

  - by Austin A.

  I'm working on a system that archives large collections of timetstamped images. Part of the system deals with saving an image to a growing .zip file. This morning I noticed that the log system said that an image was successfully downloaded and placed in the zip file, but when I downloaded the .zip (from an apache alias running on our server), the images didn't match the log. For example, although the log said that camera 3484 captured on January 17, 2011, when I download from the apache alias, the downloaded zip file only contains images up to January 14. So, I sshed onto the server, and unzipped the file in its own directory, and that zip file has images from January 14 to today (January 17). What strikes me as odd is that this should be the exact same file as the one I downloaded from the apache alias. Other experiments: I scp-ed the file from the server to my local machine, and the zip file has the newer images. But when I use an SCP client (in this case, Fugu for OSX), I get the zip file for the older images. In short: unzipping a file on the server or after downloading through scp or after downloading through wget gives one zip file, but unzipping a file from Chrome, Firefox, or SCP client gives a different zip file, when they should be exactly the same. Unzipping on the server...

• Router 2wire, Slackware desktop in DMZ mode, iptables policy aginst ping, but still pingable

  - by user135501

  I'm in DMZ mode, so I'm firewalling myself, stealthy all ok, but I get faulty test results from Shields Up that there are pings. Yesterday I couldn't make a connection to game servers work, because ping block was enabled (on the router). I disabled it, but this persists even due to my firewall. What is the connection between me and my router in DMZ mode (for my machine, there is bunch of others too behind router firewall)? When it allows router affecting if I'm pingable or not and if router has setting not blocking ping, rules in my iptables for this scenario do not work. Please ignore commented rules, I do uncomment them as I want. These two should do the job right? iptables -A INPUT -p icmp --icmp-type echo-request -j DROP echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all Here are my iptables: #!/bin/sh # Begin /bin/firewall-start # Insert connection-tracking modules (not needed if built into the kernel). #modprobe ip_tables #modprobe iptable_filter #modprobe ip_conntrack #modprobe ip_conntrack_ftp #modprobe ipt_state #modprobe ipt_LOG # allow local-only connections iptables -A INPUT -i lo -j ACCEPT # free output on any interface to any ip for any service # (equal to -P ACCEPT) iptables -A OUTPUT -j ACCEPT # permit answers on already established connections # and permit new connections related to established ones (eg active-ftp) iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT #Gamespy&NWN #iptables -A INPUT -p tcp -m tcp -m multiport --ports 5120:5129 -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 6667 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 28910 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 29900 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 29901 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 29920 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p udp -m udp -m multiport --ports 5120:5129 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 6500 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 27900 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 27901 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 29910 -j ACCEPT # Log everything else: What's Windows' latest exploitable vulnerability? iptables -A INPUT -j LOG --log-prefix "FIREWALL:INPUT" # set a sane policy: everything not accepted > /dev/null iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT DROP iptables -A INPUT -p icmp --icmp-type echo-request -j DROP # be verbose on dynamic ip-addresses (not needed in case of static IP) echo 2 > /proc/sys/net/ipv4/ip_dynaddr # disable ExplicitCongestionNotification - too many routers are still # ignorant echo 0 > /proc/sys/net/ipv4/tcp_ecn #ping death echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all # If you are frequently accessing ftp-servers or enjoy chatting you might # notice certain delays because some implementations of these daemons have # the feature of querying an identd on your box for your username for # logging.

Edit: Since posting this, I also noticed that the default gateways on my 2 NICs keep getting zeroed out. Does anyone know a fix for this?

• Too many Bind query (cache) denied, DNS attack?

  - by Jake

  Once Bind crashed and I did: tail -f /var/log/messages I see a massive number of logs every second. Is this a DNS attack? or is there something wrong? Sometimes I see a domain in logs like this: dOmAin.com (upper and lower). As you see there is only one single domain in the logs with different IPs Oct 10 02:21:26 mail named[20831]: client 74.125.189.18#38921: query (cache) 'ns1.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.144.171#38833: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.17#42428: query (cache) 'ns2.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.27#37899: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 193.203.82.66#39263: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.170#59723: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 80.169.197.66#32903: query (cache) 'dOmAin.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 134.58.60.1#47558: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.34#47387: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.8#59392: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.19#64395: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 217.72.163.3#42190: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 83.146.21.252#22020: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.116#57342: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 193.203.82.66#52020: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.72#64317: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 80.169.197.66#31989: query (cache) 'dOmAin.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.18#47436: query (cache) 'ns2.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.16#44005: query (cache) 'ns1.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 85.132.31.10#50379: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 94.241.128.3#60106: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 85.132.31.10#59118: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 212.95.135.78#27811: query (cache) 'domain.com/A/IN' denied /etc/resolv.conf ; generated by /sbin/dhclient-script nameserver 4.2.2.4 nameserver 8.8.4.4 Bind config: // generated by named-bootconf.pl options { directory "/var/named"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below.

• Pushing DNSSEC updates with offline keys

  - by eggyal

  In a non-professional capacity, I look after the DNS of some 18 domains: mostly personal/vanity domains for immediate family. I outsource the whole shebang to an inexpensive managed hosting provider with a web interface through which I manage the zones; since the provider also offers DNSSEC, I have successfully deployed that too. These domains are so unimportant that an attack targetted against them seems much less likely than a general compromise of my provider's systems, at which point the records of all their customers might be changed to misdirect traffic (perhaps with extremely long TTLs). DNSSEC could protect against such an attack, but only if the zone's private keys are not held by the hosting provider. So, I wonder: how can one keep DNSSEC private keys offline yet still transfer signed zones to an outsourced DNS host? The most obvious answer (to me, at least) is to run one's own shadow/hidden master (from which the provider can slave) and then copy offline-signed zonefiles to the master as required. The problem is that the only machine I (want to*) control is my personal laptop, which usually connects from a typical home ADSL (behind NAT over a dynamically-assigned IP address). Having them slave from that (e.g. with a very long Expiry time on the zone for periods when my laptop is offline/unavailable) would not only require a Dynamic DNS record from which they can slave (if indeed they can slave from a named host rather than a static IP address), but would also involve me running a DNS server on my laptop and opening both it and my home network up to the incoming zone transfer requests: not ideal. I would prefer a much more push-oriented design, whereby my laptop initiates transfer of offline-signed zonefiles/updates to the provider's servers. I looked into whether nsupdate could fit the bill: documentation is a little sketchy, but my testing (with BIND 9.7) suggests it can indeed update DNSSEC zones, but only where the server holds the keys to perform the zone signing; I have not found a way to have it take an update including the relevant RRSIG/NSEC/etc. records and have the server accept them. Is this a supported use-case? If not, I suspect the only solutions which could fit the bill will involve non-DNS-based transfer of the zone updates and would welcome recommendations that are supported by (hopefully inexpensive) hosting providers: SFTP/SCP? rsync? RDBMS replication? Proprietary API? Finally, what would be the practical implications of such a setup? Key rotation is jumping out at me as being an obvious difficulty, especially if my laptop is offline for extended periods. But the zones are extremely stable, so perhaps I could get away with long-lived ZSKs**...? * Whilst I could run a shadow/hidden master on e.g. an outsourced VPS, I dislike the overhead of having to secure / manage / monitor / maintain yet another system; not to mention the additional financial costs of so doing. ** Okay, this would enable a concerted attacker to replay outdated records—but the risk and impact of such are both tolerable in the case of these domains.

• Setting up home DNS with Ubuntu Server

  - by Zeophlite

  I have a webserver (with static IP 192.168.1.5), and I want to have my machines on my local network to be able to access it without modifying /etc/hosts (or equivalent for Windows/OSX). My router has Primary DNS server 192.168.1.5 Secondary DNS server 8.8.8.8 (Google's public DNS). Nginx is set up to server websites externally as *.example.com Internally, I want *.example.local to point to the server. My webserver has BIND9 installed, but I'm unsure of the settings. I've been through various contradicting tutorials, and so most of my settings have been clobbered. I've stripped out the lines which I'm confused about. The tutorials I looked at are http://tech.surveypoint.com/blog/installing-a-local-dns-server-behind-a-hardware-router/ and http://ubuntuforums.org/showthread.php?t=236093 . They mostly differ on what should be put in /etc/bind/zones/db.example.local and /etc/bind/zones/db.192, so I've left the conflicting lines out below. Can someone suggest what the correct lines are to give my above behaviour (namely *.example.local pointing to 192.168.1.5)? /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255 gateway 192.168.1.254 /etc/hostname avalon /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN /etc/bind/named.conf.options options { directory "/var/cache/bind"; forwarders { 8.8.8.8; 8.8.4.4; }; dnssec-validation auto; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; /etc/bind/named.conf.local zone "example.local" { type master; file "/etc/bind/zones/db.example.local"; }; zone "1.168.192.in-addr.arpa" { type master; file "/etc/bind/zones/db.192"; }; /etc/bind/zones/db.example.local $TTL 604800 @ IN SOA avalon.example.local. webadmin.example.local.

( 4 ; Serial, increment each edit 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; What do I need to add to the above files so that on a laptop on the internal network, I can type in webapp.example.local, and be served by my webserver? EDIT I made several changes to the above files on the webserver. /etc/network/interfaces (end of file) dns-nameservers 127.0.0.1 dns-search example.local /etc/bind/zones/db.example.local (end of file) @ IN NS avalon.example.local. @ IN A 192.168.1.5 avalon IN A 192.168.1.5 webapp IN A 192.168.1.5 www IN CNAME 192.168.1.5 /etc/bind/zones/db.192 (end of file) IN NS avalon.example.local. 73 IN PTR avalon.example.local. As a side note, my spare Win7 machine was able to connect directly to webapp.example.local, but for a Ubuntu 13.10 machine, I had to make the following changes as well (not on the webserver, but on a separate machine): /etc/nsswitch.conf before hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 after hosts: files dns /etc/NetworkManager/NetworkManager.conf before dns=dnsmasq after #dns=dnsmasq The issue remains that its not wildcard DNS, and so I have to add entries to /etc/bind/zones/db.example.local for webapp1, webapp2, ...

• amplified reflected attack on dns

  The term is new to me. So I have a few questions about it. I've heard it mostly happens with DNS servers? How do you protect against it? How do you know if your servers can be used as a victim?

• Optimise Apache for EC2 micro instance

  - by Shiyu Sekam

  I'm running apache2 on a EC2 micro instance with ~600 mb RAM. The instance was running for almost a year without problems, but in the last weeks it just keeps crashing, because the server reached MaxClients. The server basically runs few websites, one wordpress blog(not often used), company website(most used) and 2 small sites, which are just internal. The database for the blog runs on RDS, so there's no Mysql running on this web server. When I came to the company, the server already was setup and is running apache + mod_php + prefork. We want to migrate that in the future to a nginx + php-fpm, but it still needs further testing. So for now I have to stick with the old setup. I also use CloudFlare DDOS protection in front of the server, because it was attacked a couple of the times in the last weeks. My company don't want to pay money for a better web server at this point, so I have to stick with the micro instance also. Additionally the code for the website we run is really bad and slow and sometimes a single page load can take up to 15 seconds. The whole website is dynamic and written in PHP, so caching isn't really an option here. It's a customized search for users. I've already turned off KeepAlive, which improved the performance a little bit. My prefork config looks like the following: StartServers 2 MinSpareServers 2 MaxSpareServers 5 ServerLimit 10 MaxClients 10 MaxRequestsPerChild 100 The server just becomes unresponsive after a while running and I've run the following command to see how many connections there are: netstat | grep http | wc -l 75 Trying to restart apache helps for a short moment, but after that a while the apache process(es) become unresponsive again. I've the following modules enabled(output of apache2ctl -M) Loaded Modules: core_module (static) log_config_module (static) logio_module (static) version_module (static) mpm_prefork_module (static) http_module (static) so_module (static) alias_module (shared) authz_host_module (shared) deflate_module (shared) dir_module (shared) expires_module (shared) mime_module (shared) negotiation_module (shared) php5_module (shared) rewrite_module (shared) setenvif_module (shared) ssl_module (shared) status_module (shared) Syntax OK apache2.conf # Security ServerTokens OS ServerSignature On TraceEnable On ServerName "web.example.com" ServerRoot "/etc/apache2" PidFile ${APACHE_PID_FILE} Timeout 30 KeepAlive off User www-data Group www-data AccessFileName .htaccess <Files ~ "^\.ht"> Order allow,deny Deny from all Satisfy all </Files> <Directory /> Options FollowSymLinks AllowOverride None </Directory> DefaultType none HostnameLookups Off ErrorLog /var/log/apache2/error.log LogLevel warn EnableSendfile On #Listen 80 Include /etc/apache2/mods-enabled/*.load Include /etc/apache2/mods-enabled/*.conf Include /etc/apache2/ports.conf LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %b" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent Include /etc/apache2/conf.d/*.conf Include /etc/apache2/sites-enabled/*.conf Vhost of main site <VirtualHost *:80> ServerName www.example.com ## Vhost docroot DocumentRoot /srv/www/jenkins/Web ## Directories, there should at least be a declaration for /srv/www/jenkins/Web <Directory /srv/www/jenkins/Web> AllowOverride All Order allow,deny Allow from all </Directory> ## Load additional static includes ## Logging ErrorLog /var/log/apache2/www.example.com.error.log LogLevel warn ServerSignature Off CustomLog /var/log/apache2/www.example.com.access.log combined ## Rewrite rules RewriteEngine On RewriteCond %{HTTP_HOST} !^www.example.com$ RewriteRule ^.*$ http://www.example.com%{REQUEST_URI} [R=301,L] ## Server aliases ServerAlias www.example.invalid ServerAlias example.com ## Custom fragment <Location /srv/www/jenkins/Web/library> Order Deny,Allow Deny from all </Location> <Files ~ "^\.(.+)"> Order deny,allow deny from all </Files> </VirtualHost>

• Primefaces tabview: set the active index on tab change

  - by Virgi

  I've got a tab view that contains two tab. When I switch from tab 1 to tab 2, I'm calling some code that executes a validation and updates some values. Depending on the result of this validation, I would like to stay on tab 1, or go to tab 2, and refresh the tabs' content. My tabview: <h:form id="form"> <p:tabView id="tabview" activeIndex="#{ctrl.idx}" dynamic="true" cache="false"> <p:ajax event="tabChange" listener="#{ctrl.doStuff}" update=":form:tabview"/> <p:tab title="Tab 1" id="t1"> <h:panelGrid columns="1" cellpadding="10"> <h:outputText value="#{ctrl.s1}"/> </h:panelGrid> </p:tab> <p:tab title="Tab 2" id="t2"> <h:panelGrid columns="1" cellpadding="10"> <h:outputText value="#{ctrl.s2}"/> </h:panelGrid> </p:tab> </p:tabView> </h:form> My test code that simly changes the values: public void doStuff() { s1 = String.valueOf(Math.random()); s2 = String.valueOf(Math.random()); } I thought that changing the active tab index in my method would be enough, like that: public void doStuff() { // ... idx = 0; } On tabChange event, the method is called but the tabview components goes to the clicked tab, ignoring the idx new value. I thought adding an update attribute to p:ajax would render the whole tabview but only the tabs and/or the tabs' content is re rendered. And weirdest of all, if I change update=":form:tabview" to update=":form" or update="@form", I only receive the tab's content in the ajax response - the component disappears from the page! My bean is viewscoped, I'm using Primefaces 3.5, JSF 2.1 and Tomcat 7. Any idea? Thanks.
