• Why can't I build Deluge?

  - by hugemeow

  Deluge is a BitTorrent Client. I am trying to build it from source, since I don't have privilege to install it as root. I am using python setup.py build. But, it failed following message, why? copying deluge/ui/web/themes/images/gray/slider/slider-v-thumb.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/gray/slider copying deluge/ui/web/themes/images/gray/slider/slider-thumb.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/gray/slider copying deluge/ui/web/themes/images/gray/panel/top-bottom.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/gray/panel copying deluge/ui/web/themes/images/gray/tabs/tab-strip-bg.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/gray/tabs copying deluge/ui/web/themes/images/yourtheme/window/right-corners.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/window copying deluge/ui/web/themes/images/yourtheme/window/left-corners.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/window copying deluge/ui/web/themes/images/yourtheme/window/left-right.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/window copying deluge/ui/web/themes/images/yourtheme/window/top-bottom.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/window creating build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/slider copying deluge/ui/web/themes/images/yourtheme/slider/slider-v-thumb.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/slider copying deluge/ui/web/themes/images/yourtheme/slider/slider-thumb.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/slider copying deluge/ui/web/themes/images/yourtheme/slider/slider-bg.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/slider copying deluge/ui/web/themes/images/yourtheme/slider/slider-v-bg.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/slider copying deluge/ui/web/themes/images/yourtheme/panel/top-bottom.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/panel copying deluge/ui/web/themes/images/yourtheme/grid/hmenu-lock.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/grid copying deluge/ui/web/themes/images/yourtheme/grid/hmenu-unlock.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/grid copying deluge/ui/web/themes/images/yourtheme/tabs/tab-strip-bg.png -> build/lib.linux-x86_64-2.4/deluge/ui/web/themes/images/yourtheme/tabs running build_ext building 'libtorrent' extension gcc -pthread -shared -L/usr/lib64 -L/opt/local/lib -lboost_filesystem -lboost_date_time -lboost_iostreams -lboost_python -lboost_thread -lpthread -lssl -lz -o build/lib.linux-x86_64-2.4/deluge/libtorrent.so /usr/bin/ld: cannot find -lboost_filesystem collect2: ld returned 1 exit status error: command 'gcc' failed with exit status 1 [mirror@innov deluge-1.3.5]$ echo $? 1 Edit 1: gcc version and os information $(which gcc) --version gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-52) Copyright (C) 2006 Free Software Foundation, Inc.

• Monit won't run

  - by Yaniro

  I have two identical EC2 instances (the second is a replica of the first), running Gentoo. The first instance has monit running which monitors a single process and some system resources and functions great. In the second instance, monit runs but quits right away. The configuration is similar on both instances so are the versions of monit. monit.log shows: [GMT Oct 3 08:36:41] info : monit daemon with PID 5 awakened Final lines on strace monit show: write(2, "monit daemon with PID 5 awakened"..., 33monit daemon with PID 5 awakened ) = 33 time(NULL) = 1349252827 open("/etc/localtime", O_RDONLY) = 4 fstat64(4, {st_mode=S_IFREG|0644, st_size=118, ...}) = 0 fstat64(4, {st_mode=S_IFREG|0644, st_size=118, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb773a000 read(4, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\1\0\0\0\1\0\0\0\0"..., 4096) = 118 _llseek(4, -6, [112], SEEK_CUR) = 0 read(4, "\nGMT0\n", 4096) = 6 close(4) = 0 munmap(0xb773a000, 4096) = 0 write(3, "[GMT Oct 3 08:27:07] info :"..., 33) = 33 write(3, "monit daemon with PID 5 awakened"..., 33) = 33 waitpid(-1, NULL, WNOHANG) = -1 ECHILD (No child processes) close(3) = 0 exit_group(0) = ?

• httpd.conf configuration - for internal/external access

  - by tom smith

  hey. after a lot of trail/error/research, i've decided to post here in the hopes that i can get clarification on what i've screwed up... i've got a situation where i have multiple servers behind a router/firewall. i want to be able to access the sites i have from an internal and external url/address, and get the same site. i have to use portforwarding on the router, so i need to be able to use proxyreverse to redirect the user to the approriate server, running the apache/web app... my setup the external urls joomla.gotdns.com forge.gotdns.com both of these point to my router's external ip address (67.168.2.2) (not really) the router forwards port 80 to my server lserver6 192.168.1.56 lserver6 - 192.168.1.56 lserver9 - 192.168.1.59 lserver6 - joomla app lserver9 - forge app i want to be able to have the httpd process (httpd.conf) configured on lserver6 to be able to allow external users accessing the system (foo.gotdns.com) be able to access the joomla app on lserver6 and the same for the forge app running on lserver9 at the same time, i would also like to be able to access the apps from the internal servers, so i'd need to be able to somehow configure the vhost setup/proxyreverse setup to handle the internal access... i've tried setting up multiple vhosts with no luck.. i've looked at the different examples online.. so there must be something subtle that i'm missing... the section of my httpd.conf file that deals with the vhost is below... if there's something else that's needed, let me know and i can post it as well.. thanks -tom ##joomla - file /etc/httpd/conf.d/joomla.conf Alias /joomla /var/www/html/joomla <Directory /var/www/html/joomla> </Directory> # Use name-based virtual hosting. #NameVirtualHost *:80 # NOTE: NameVirtualHost cannot be used without a port specifier # (e.g. :80) if mod_ssl is being used, due to the nature of the # SSL protocol. # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for requests without a known # server name. #<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot /www/docs/dummy-host.example.com # ServerName dummy-host.example.com # ErrorLog logs/dummy-host.example.com-error_log # CustomLog logs/dummy-host.example.com-access_log common #</VirtualHost> NameVirtualHost 192.168.1.56:80 <VirtualHost 192.168.1.56:80> #ServerAdmin [email protected] #DocumentRoot /var/www/html #ServerName lserver6.tmesa.com #ServerName fforge.tmesa.com ServerName fforge.gotdns.com:80 #ErrorLog logs/dummy-host.example.com-error_log #CustomLog logs/dummy-host.example.com-access_log common #ProxyRequests Off ProxyPass / http://192.168.1.81:80/ ProxyPassReverse / http://192.168.1.81:80/ </VirtualHost> <VirtualHost 192.168.1.56:80> #ServerAdmin [email protected] DocumentRoot /var/www/html/joomla #ServerName lserver6.tmesa.com #ServerName fforge.tmesa.com ServerName 192.168.1.56:80 #ErrorLog logs/dummy-host.example.com-error_log #CustomLog logs/dummy-host.example.com-access_log common #ProxyRequests Off </VirtualHost>

• Setting up RADIUS + LDAP for WPA2 on Ubuntu

  - by Morten Siebuhr

  I'm setting up a wireless network for ~150 users. In short, I'm looking for a guide to set RADIUS server to authenticate WPA2 against a LDAP. On Ubuntu. I got a working LDAP, but as it is not in production use, it can very easily be adapted to whatever changes this project may require. I've been looking at FreeRADIUS, but any RADIUS server will do. We got a separate physical network just for WiFi, so not too many worries about security on that front. Our AP's are HP's low end enterprise stuff - they seem to support whatever you can think of. All Ubuntu Server, baby! And the bad news: I now somebody less knowledgeable than me will eventually take over administration, so the setup has to be as "trivial" as possible. So far, our setup is based only on software from the Ubuntu repositories, with exception of our LDAP administration web application and a few small special scripts. So no "fetch package X, untar, ./configure"-things if avoidable. UPDATE 2009-08-18: While I found several useful resources, there is one serious obstacle: Ignoring EAP-Type/tls because we do not have OpenSSL support. Ignoring EAP-Type/ttls because we do not have OpenSSL support. Ignoring EAP-Type/peap because we do not have OpenSSL support. Basically the Ubuntu version of FreeRADIUS does not support SSL (bug 183840), which makes all the secure EAP-types useless. Bummer. But some useful documentation for anybody interested: http://vuksan.com/linux/dot1x/802-1x-LDAP.html http://tldp.org/HOWTO/html_single/8021X-HOWTO/#confradius UPDATE 2009-08-19: I ended up compiling my own FreeRADIUS package yesterday evening - there's a really good recipe at http://www.linuxinsight.com/building-debian-freeradius-package-with-eap-tls-ttls-peap-support.html (See the comments to the post for updated instructions). I got a certificate from http://CACert.org (you should probably get a "real" cert if possible) Then I followed the instructions at http://vuksan.com/linux/dot1x/802-1x-LDAP.html. This links to http://tldp.org/HOWTO/html_single/8021X-HOWTO/, which is a very worthwhile read if you want to know how WiFi security works. UPDATE 2009-08-27: After following the above guide, I've managed to get FreeRADIUS to talk to LDAP: I've created a test user in LDAP, with the password mr2Yx36M - this gives an LDAP entry roughly of: uid: testuser sambaLMPassword: CF3D6F8A92967E0FE72C57EF50F76A05 sambaNTPassword: DA44187ECA97B7C14A22F29F52BEBD90 userPassword: {SSHA}Z0SwaKO5tuGxgxtceRDjiDGFy6bRL6ja When using radtest, I can connect fine: > radtest testuser "mr2Yx36N" sbhr.dk 0 radius-private-password Sending Access-Request of id 215 to 130.225.235.6 port 1812 User-Name = "msiebuhr" User-Password = "mr2Yx36N" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 rad_recv: Access-Accept packet from host 130.225.235.6 port 1812, id=215, length=20 > But when I try through the AP, it doesn't fly - while it does confirm that it figures out the NT and LM passwords: ... rlm_ldap: sambaNTPassword -> NT-Password == 0x4441343431383745434139374237433134413232463239463532424542443930 rlm_ldap: sambaLMPassword -> LM-Password == 0x4346334436463841393239363745304645373243353745463530463736413035 [ldap] looking for reply items in directory...

• Cannot join Win7 workstations to Win2k8 domain

  - by wfaulk

  I am trying to connect a Windows 7 Ultimate machine to a Windows 2k8 domain and it's not working. I get this error: Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt. DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "example.local": The query was for the SRV record for _ldap._tcp.dc._msdcs.example.local The following domain controllers were identified by the query: dc1.example.local dc2.example.local However no domain controllers could be contacted. Common causes of this error include: Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses. Domain controllers registered in DNS are not connected to the network or are not running. The client is in an office connected remotely via MPLS to the data center where our domain controllers exist. I don't seem to have anything blocking connectivity to the DCs, but I don't have total control over the MPLS circuit, so it's possible that there's something blocking connectivity. I have tried multiple clients (Win7 Ultimate and WinXP SP3) in the one office and get the same symptoms on all of them. I have no trouble connecting to either of the domain controllers, though I have, admittedly, not tried every possible port. ICMP, LDAP, DNS, and SMB connections all work fine. Client DNS is pointing to the DCs, and "example.local" resolves to the two IP addresses of the DCs. I get this output from the NetLogon Test command line utility: C:\Windows\System32>nltest /dsgetdc:example.local Getting DC name failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN I have also created a separate network to emulate that office's configuration that's connected to the DC network via LAN-to-LAN VPN instead of MPLS. Joining Windows 7 computers from that remote network works fine. The only difference I can find between the two environments is the intermediate connectivity, but I'm out of ideas as to what to test or how to do it. What further steps should I take? (Note that this isn't actually my client workstation and I have no direct access to it; I'm forced to do remote hands access to it, which makes some of the obvious troubleshooting methods, like packet sniffing, more difficult. If I could just set up a system there that I could remote into, I would, but requests to that effect have gone unanswered.) 2011-08-25 update: I had DCDIAG.EXE run on a client attempting to join the domain: C:\Windows\System32>dcdiag /u:example\adminuser /p:********* /s:dc2.example.local Directory Server Diagnosis Performing initial setup: Ldap search capabality attribute search failed on server dc2.example.local, return value = 81 This sounds like it was able to connect via LDAP, but the thing that it was trying to do failed. But I don't quite follow what it was trying to do, much less how to reproduce it or resolve it. 2011-08-26 update: Using LDP.EXE to try and make an LDAP connection directly to the DCs results in these errors: ld = ldap_open("10.0.0.1", 389); Error <0x51: Fail to connect to 10.0.0.1. ld = ldap_open("10.0.0.2", 389); Error <0x51: Fail to connect to 10.0.0.2. ld = ldap_open("10.0.0.1", 3268); Error <0x51: Fail to connect to 10.0.0.1. ld = ldap_open("10.0.0.2", 3268); Error <0x51: Fail to connect to 10.0.0.2. This would seem to point fingers at LDAP connections being blocked somewhere. (And 0x51 == 81, which was the error from DCDIAG.EXE from yesterday's update.) I could swear I tested this using TELNET.EXE weeks ago, but now I'm thinking that I may have assumed that its clearing of the screen was telling me that it was waiting and not that it had connected. I'm tracking down LDAP connectivity problems now. This update may become an answer.

• Broken cups installation on a ubuntu server 64

  - by user67046

  Hi, I am having trouble with an cups installation. It seems to be in a broken state. When i try to reinstall it it stalls, the same if i try to remove it completely. I am running the server version 64 bit of Ubuntu 10.10 with kernel Linux version 2.6.35-22-server. When i try to start the cups daemon with the following command sudo service cups start It just stays there and nothing happens. I have tried to remove it, to be able to reinstall it, with the following command sudo apt-get purge cups It finally stalls with the following message Removing cups ... After that nothing happens. The process tree for the apt-get command looks like this. 1404 1404 1404 ? 00:00:00 sshd 26495 26495 26495 ? 00:00:00 sshd 26581 26495 26495 ? 00:00:00 sshd 26582 26582 26582 pts/4 00:00:00 bash 27158 27158 26582 pts/4 00:00:00 apt-get 27172 27172 27172 pts/2 00:00:00 dpkg 27176 27172 27172 pts/2 00:00:00 cups.prerm 27178 27172 27172 pts/2 00:00:00 stop I have tried to leave the process running for a while to see if i get any error messages but without success.

• Exchange Server 2007 Setup

  - by AlamedaDad

  Hi, I'm working on a upgrade to Exchange 2007 and I wanted to get some advise on hardware choices. We currently have an Exchange 2003 STD server with 400 users split between 6 AD Sites, that is housed on a single server. We need to move to a redundant, fault tolerant system to support our users. I'm planning on installing 2 Dell 1950 servers with W2k8-std to act as CAS and Hub servers, with NLB to allow abstraction of the actual server name to the users. There won't be an edge system since we have a Barracuda box already that will handle in/out spam/virus filtering. Backend I'm planning on 2 mailbox servers which will be Dell 2950s with 16GB RAM, 2 either dual-core or quad-core CPUs and 6 300GB SAS drives in some RAID config. These systems will be clustered using W2k8 Ent clustering and running CCR in Exchange. My questions are as follows: Is 16GB enough RAM for serving that many mailboxes along with the windows clustering and ccr? I'm trying to figure out disk layouts and I'm unsure of whether to use all local disk or some local and some SAN, via an OpenFiler iSCSI server. The SAN would be a Dell 2850 with 6 - 300GB SCSI drives and a PERC controller to slice as I want, with 8GB RAM. Option 1: 2 drives, RAID 1 - OS 2 drives, RAID 1 - Logs 2 drives, RAID 1 - Mail stores Option 2: 2 drives, RAID 1 - OS and logs 4 drives, RAID 5 - Mail Stores and scratch space for eseutil. Option 3: 2 drives, RAID 1 - OS 2 drives, RAID 1 - Logs 2 drives, RAID 0 - scratch space ~300GB iSCSI volume for mail stores Option 4: 2 drives, RAID 1 - OS 4 drives, RAID 5 - scratch space ~300GB iSCSI volume for mail stores ~300GB iSCSI volume for logs I have 2 sockets for CPUs and need to chose between dual and quad cores. The dual core have faster clocks but less cache and I'm thinking older architecture. Am I better off with more cores and cache while sacraficing clock speed? I am planning on adding the new E2K7 cluster to the E2K3 server and then move each mailbox over, all at once, then remove the old server. This seems more complicated than simply getting rid of the 2003 server and then adding the 2007 cluster and restoring the mailboxes using PowerControls or exmerge. The migration option lets me do this on my time, where a cutover means it all needs to work at once. If I go with the cutover method, how can I prebuild the servers and add them to the domain right after removing the 2003 server, or can't I? I think the answer is no and the migration is my only real option if I want to prebuild. I need to also migrate about 30GB of Public Folders. Is there anything special about this, other than specifying in the E2K7 install that I want older Outlook clients and PF's setup? I guess I could even keep the E2K3 server to host just the PFs? Lastly, if I have a mix of Outlook 200, 2003 and 2007 what do I need to do to make sure they all have access to the GAL and OAB? At time of cutover, we'll be at like 90% 2007, but we will have some older stuff around. My plan is to use Outlook Anywhere on laptops that are used outside the physical network. Are there any gotchas involved in that? I'm even thinking about using is for all Outlook clients, does anyone do that? The reason I'm considering it is that our WAN is really VPN tunnels over internet connections, so not a fully messhed, stable WAN. Thank you all very much for the assistance in advance and I look forward to discussion of these points! Regards...Michael

• Tomcat dying silently on regular basis

  - by Hendrik

  My tomcat (6.0.32, Java Sun 1.6.0_22-b04 on Ubuntu 10.04) keeps crashing multiple times daily without any specific output in catalina.out. This usually happens on high load (see top output). Update: The pid-file is properly removed when this happens.

I can start up the service and it will run for a few days or just minutes before dying again. Is there somewhere else i could look for output? Could the kernel start killing threads due to a lack of ressources and by that bring the VM down?

• Logging to MySQL without empty rows/skipped records?

  - by Lee Ward

  I'm trying to figure out how to make Squid proxy log to MySQL. I know ACL order is pretty important but I'm not sure if I understand exactly what ACLs are or do, it's difficult to explain, but hopefully you'll see where I'm going with this as you read! I have created the lines to make Squid interact with a helper in squid.conf as follows: external_acl_type mysql_log %LOGIN %SRC %PROTO %URI php /etc/squid3/custom/mysql_lg.php acl ex_log external mysql_log http_access allow ex_log The external ACL helper (mysql_lg.php) is a PHP script and is as follows: error_reporting(0); if (! defined(STDIN)) { define("STDIN", fopen("php://stdin", "r")); } $res = mysql_connect('localhost', 'squid', 'testsquidpw'); $dbres = mysql_select_db('squid', $res); while (!feof(STDIN)) { $line = trim(fgets(STDIN)); $fields = explode(' ', $line); $user = rawurldecode($fields[0]); $cli_ip = rawurldecode($fields[1]); $protocol = rawurldecode($fields[2]); $uri = rawurldecode($fields[3]); $q = "INSERT INTO logs (id, user, cli_ip, protocol, url) VALUES ('', '".$user."', '".$cli_ip."', '".$protocol."', '".$uri."');"; mysql_query($q) or die (mysql_error()); if ($fault) { fwrite(STDOUT, "ERR\n"); }; fwrite(STDOUT, "OK\n"); } The configuration I have right now looks like this: ## Authentication Handler auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 30 auth_param negotiate program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param negotiate children 5 # Allow squid to update log external_acl_type mysql_log %LOGIN %SRC %PROTO %URI php /etc/squid3/custom/mysql_lg.php acl ex_log external mysql_log http_access allow ex_log acl localnet src 172.16.45.0/24 acl AuthorizedUsers proxy_auth REQUIRED acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl CONNECT method CONNECT acl blockeddomain url_regex "/etc/squid3/bl.acl" http_access deny blockeddomain deny_info ERR_BAD_GENERAL blockeddomain # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # Allow the internal network access to this proxy http_access allow localnet # Allow authorized users access to this proxy http_access allow AuthorizedUsers # FINAL RULE - Deny all other access to this proxy http_access deny all From testing, the closer to the bottom I place the logging lines the less it logs. Oftentimes, it even places empty rows in to the MySQL table. The file-based logs in /var/log/squid3/access.log are correct but many of the rows in the access logs are missing from the MySQL logs. I can't help but think it's down to the order I'm putting lines in because I want to log everything to MySQL, unauthenticated requests, blocked requests, which category blocked a specific request. The reason I want this in MySQL is because I'm trying to have everything managed via a custom web-based frontend and want to avoid using any shell commands and access to system log files if I can help it. The end result is to make it as easy as possible to maintain without keeping staff waiting on the phone whilst I add a new rule and reload the server! Hopefully someone can help me out here because this is very much a learning experience for me and I'm pretty stumped. Many thanks in advance for any help!

• Cannot read status the monit daemon, even with allowed group

  - by jefflunt

  I cannot seem to get monit status or other CLI commands to work. I've built monit v5.8 to run on a Raspberry Pi. I'm able to add services to be monitored, and the web interface can be accessed just fine, as I've set it up for public read-only access (it's a test server, not my final production setup, so not a big deal right now). Problem is, when I run monit status while logged in as root I get: # monit status monit: cannot read status from the monit daemon I also have monit started on boot via this /etc/inittab file entry: mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc I've verified that monit is running, and I'm getting email alerts anytime I either kill the monit process manually, or reboot my raspberry pi. So, next I check my monitrc file permissions to see which group is allowed access. # ls -al /etc/monitrc -rw------- 1 root root 2359 Aug 24 14:48 /etc/monitrc Here's my relevant allow section of the control file. set httpd port 80 allow [omitted] readonly allow @root allow localhost allow 0.0.0.0/0.0.0.0 Also tried setting permissions on this file to 640 to allow group read permissions, but no matter what I try I either get the same error as noted above, or when the permissions are set to 640 I get: # monit status monit: The control file '/etc/monitrc' must have permissions no more than -rwx------ (0700); right now permissions are -rw-r----- (0640). What am I missing here? I know that the httpd must be enabled, as that's the interface that the CLI uses to get information (or so I've read), so I've done that. And in terms of monit doing its monitoring job and sending email alerts, that's all working as well. Here's my entire monitrc file - again, this is version v5.8, and it was build with both PAM and SSL support. The process runs under the root user: # Global settings set daemon 300 with start delay 5 set logfile /var/log/monit.log set pidfile /var/run/monit.pid set idfile /var/run/.monit.id set statefile /var/run/.monit.state # Mail alerts ## Set the list of mail servers for alert delivery. Multiple servers may be ## specified using a comma separator. If the first mail server fails, Monit # will use the second mail server in the list and so on. By default Monit uses # port 25 - it is possible to override this with the PORT option. # set mailserver smtp.gmail.com port 587 username [omitted] password [omitted] using tlsv1 ## Send status and events to M/Monit (for more informations about M/Monit ## see http://mmonit.com/). By default Monit registers credentials with ## M/Monit so M/Monit can smoothly communicate back to Monit and you don't ## have to register Monit credentials manually in M/Monit. It is possible to ## disable credential registration using the commented out option below. ## Though, if safety is a concern we recommend instead using https when ## communicating with M/Monit and send credentials encrypted. # # set mmonit http://monit:[email protected]:8080/collector # # and register without credentials # Don't register credentials # # ## Monit by default uses the following format for alerts if the the mail-format ## statement is missing:: set mail-format { from: [email protected] subject: $SERVICE $DESCRIPTION message: $EVENT Service: $SERVICE Date: $DATE Action: $ACTION Host: $HOST Description: $DESCRIPTION Monit instance provided by chicagomeshnet.com } # Web status page set httpd port 80 allow [omitted] readonly allow @root allow localhost allow 0.0.0.0/0.0.0.0 ## You can set alert recipients whom will receive alerts if/when a ## service defined in this file has errors. Alerts may be restricted on ## events by using a filter as in the second example below.

• Consistent PHP _SERVER variables between Apache and nginx?

  - by Alix Axel

  I'm not sure if this should be asked here or on ServerFault, but here it goes... I am trying to get started on nginx with PHP-FPM, but I noticed that the server block setup I currently have (gathered from several guides including the nginx Pitfalls wiki page) produces $_SERVER variables that are different from what I'm used to seeing in Apache setups. After spending the last evening trying to "fix" this, I decided to install Apache on my local computer and gather the variables that I'm interested in under different conditions so that I could try and mimic them on nginx. The Apache setup I've on my computer has only one mod_rewrite rule: RewriteEngine On RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ /index.php/$1 [L] And these are the values I get for different request URIs (left is Apache, right is nginx): localhost/ - http://www.mergely.com/GnzBHRV1/ localhost/foo/bar/baz/?foo=bar - http://www.mergely.com/VwsT8oTf/ localhost/index.php/foo/bar/baz/?foo=bar - http://www.mergely.com/VGEFehfT/ What configuration directives would allow me to get similar values on requests handled by nginx? My current configuration in nginx is: server { listen 80; listen 443 ssl; server_name default; ssl_certificate /etc/nginx/certificates/dummy.crt; ssl_certificate_key /etc/nginx/certificates/dummy.key; root /var/www/default/html; index index.php index.html; autoindex on; location / { try_files $uri $uri/ /index.php; } location ~ /(?:favicon[.]ico|robots[.]txt)$ { log_not_found off; } location ~* [.]php { #try_files $uri =404; include fastcgi_params; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_split_path_info ^(.+[.]php)(/.+)$; } location ~* [.]ht { deny all; } } And my fastcgi_params file looks like this: fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; 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 SCRIPT_FILENAME $document_root$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 HTTPS $https; I know that the try_files $uri =404; directive is commented and that it is a security vulnerability but, if I uncomment it, the third request (localhost/index.php/foo/bar/baz/?foo=bar) will return a 404. It's also worth noting that my PHP cgi.fix_pathinfo in On (contrary to what some of the guides recommend), if I try to set it to Off, I'm presented with a "Access denied." message on every PHP request. I'm running PHP 5.4.8 and nginx/1.1.19. I don't know what else to try... Help?

• apache2 namevirtualhost resolving wrong site

  - by joe

  Running apache 2.2.6. I'm setting up a development environment. dev and production will be hosted on the same machine, same IP address. DNS entries like prod.domain.com and dev.domain.com point to the same IP. * Imprortant: it is required that dev and prod are otherwise completely separate. Each will run it's own apache instance. Each will use it's own apache configuration. Each, prod and dev, will host http and https. I have this set up and working, but not as restrictive as I'd like. For instance, the production config: NameVirtualHost *:80 NameVirtualHost *:443 <VirtualHost *:80 > ServerName prod.domain.com # ... etc </VirtualHost> <VirtualHost *:443 > ServerName prod.domain.com # ... etc </VirtualHost> The dev site is set up similarly, using ports 8080 and 4443. Each site works fine. But assuming both apaches are running, one can also hit "cross-site" by mistake. So, inadvertently hitting prod.domain.com:8080 successfully returns a page from the dev site. It would be much better if this failed completely. This is a bit more difficult to solve (for me) because of the need for two apache configs. If all in one, the single process would have full knowledge of everything. So, I tried to solve this with brute force, including virtual hosts for the "other" site, with something that would fail, like no access to documentroot. But apache then inexplicably finds the "wrong" virtual host. Here's the full config for production, with the dummy dev configs. NameVirtualHost *:80 NameVirtualHost *:443 # ---------------------------------------------- # DUMMY HOSTS <VirtualHost *:8080 > ServerName dev.domain.com:8080 DocumentRoot /tmp/ <Directory /tmp/ > Order deny,allow Deny from all </Directory> </VirtualHost> <VirtualHost *:4443 > ServerName dev.domain.com:4443 DocumentRoot /tmp/ <Directory /tmp/ > Order deny,allow Deny from all </Directory> </VirtualHost> # ---------------------------------------------- # REAL PRODUCTION HOSTS <VirtualHost *:80 > ServerName prod.domain.com:80 DocumentRoot /something/valid/ <Directory /something/valid/> Order allow,deny Allow from all </Directory> </VirtualHost> <VirtualHost *:443 > ServerName prod.domain.com:443 DocumentRoot /something/valid/ <Directory /something/valid/> Order allow,deny Allow from all </Directory> # .... other valid ssl setup </VirtualHost> Here's the strange thing. With this configuration, a prod.domain.com:80 hit succeeds. But a prod.domain.com:443 hit fails, because it finds the dev.domain.com:4443 instead. I've also tried removing the port from the ServerName, but it still doesn't work. Sorry for the long question. Hopefully this is enough information. Thanks in advance for any help.

• Remote Desktop failed logon event 4625 not logging correctly on 2008 Terminal Services server

  - by Zone12

  When I use the new remote desktop with ssl and try to log on with bad credentials it logs a 4625 event as expected. The problem is, it doesn't log the ip address, so I can't block malicious logons in our firewall. The event looks like this: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Microsoft-Windows-Security-Auditing" Guid="{00000000-0000-0000-0000-000000000000}" /> <EventID>4625</EventID> <Version>0</Version> <Level>0</Level> <Task>12544</Task> <Opcode>0</Opcode> <Keywords>0x8010000000000000</Keywords> <TimeCreated SystemTime="2012-04-13T06:52:36.499113600Z" /> <EventRecordID>467553</EventRecordID> <Correlation /> <Execution ProcessID="544" ThreadID="596" /> <Channel>Security</Channel> <Computer>ontheinternet</Computer> <Security /> </System> <EventData> <Data Name="SubjectUserSid">S-1-0-0</Data> <Data Name="SubjectUserName">-</Data> <Data Name="SubjectDomainName">-</Data> <Data Name="SubjectLogonId">0x0</Data> <Data Name="TargetUserSid">S-1-0-0</Data> <Data Name="TargetUserName">notauser</Data> <Data Name="TargetDomainName">MYSERVER-PC</Data> <Data Name="Status">0xc000006d</Data> <Data Name="FailureReason">%%2313</Data> <Data Name="SubStatus">0xc0000064</Data> <Data Name="LogonType">3</Data> <Data Name="LogonProcessName">NtLmSsp</Data> <Data Name="AuthenticationPackageName">NTLM</Data> <Data Name="WorkstationName">MYSERVER-PC</Data> <Data Name="TransmittedServices">-</Data> <Data Name="LmPackageName">-</Data> <Data Name="KeyLength">0</Data> <Data Name="ProcessId">0x0</Data> <Data Name="ProcessName">-</Data> <Data Name="IpAddress">-</Data> <Data Name="IpPort">-</Data> </EventData> </Event> It seems because the logon type is 3 and not 10 like the old rdp sessions, the ip address and other information is not stored. The machine I am trying to connect from is on the internet and not on the same network as the server. Does anyone know where this information is stored (and what other events are generated with a failed logon)? Any help will be much appreciated.

• Strange enduser experience with Liferay, Glassfish and Apache on RedHat

  - by Pete Helgren

  Tried multiple forums to get to the bottom of this. I hope I can get some direction here: Here is the stack I am working with: Red Hat Enterprise Linux Server release 5.6 (Tikanga) Liferay 6.0.6 on Glassfish 3.0.1 MySQL 5.0.77 Apache 2.2.3 The Liferay portal provides a variety of portlets to end users. Static content (web pages), static resources (primarily pdf and mp3 files 1mb - 80mb in size), File upload and download capabilities (primarily 40-60mb mp3 files) and online streaming of those MP3 files. Here is the strange end user experiences: Under normal load: (20-30) users uploading, downloading or streaming files and 20-30 accessing static content (some of it downloads), we see the following: 1) Clicking a link triggers the download of a portion of an MP3 (the portion is a few seconds long). 2) Clicking on a link tiggers the download of the page content rather than rendering. 3) Clicking a link causes the page to dump binary data to the end user rather than the expected content. 4) Clicking a link returns the text of a javascript file rather than rendering the page. Each occurrence is totally random (or appears so). Sometimes it works, sometimes it doesn't. It seems to have no relation to browser or client OS. The strange events seem to occur much more frequently when using an SSL connection rather than regular http. Apache serves as a proxy server only (reverse). It basically passes all the requests through to Glassfish. There isn't any static content proxy served by Apache. We rebuilt the entire stack from scratch and redeployed the portlet wars and still have the same issues. Liferay is running as a single server (not clustered). We disabled mod_cache in Apache. The problems are more frequent as the server load grows. This morning the load is pretty light and we are seeing few problems but the use of the site will grow, particularly tonight around 9pm CST through Wednesday morning. You could try the site (http://preview.bsfinternational.org) during those times and I would expect that you might experience one of the weirdnesses as you randomly click links on the site (https is invoked only when signed in). Again, https seems to exacerbate the issue. This seems very much like a caching issue but I don't know where in the stack to start peeling the onion. Apache? Liferay? Glassfish? MySQL? Maybe even Redhat? We are stumped and most forums we have posted to (LifeRay and Glassfish) have returned very few suggestions. I just need an idea of where to start looking. I understand that we could have a portlet EDIT: Opening the files in a Hex editor that appear to be pages that download rather than render, we see that the first 4000 characters are "junk" and then the "HTTP/1.1 ...." 'normal' header is seen. So something is dumping a jumble of characters up to offset 4000 (when viewing it in a Hex editor). Perhaps a clue? Ideas?

• Disable error_log. Error_log flooding

  - by user36646

  Hello, i got an webserver running and old version of gambio (xt:commerce fork). The error_log in the dir over the public_html is flooding with errors. About 30mb in 15min. How can I disable this log? I can't fix all the errors. Here are a few examples of the errors: [warn] mod_fcgid: stderr: PHP Notice: Undefined variable: key in /usr/www/users/foo//includes/classes/class.inputfilter.php on line 98 [warn] mod_fcgid: stderr: PHP Notice: Undefined index: in /usr/www/users/foo/templ [warn] mod_fcgid: stderr: in /usr/www/users/foo/templates/gambio/source/inc/xtc_show_category_sectionc.inc.php on line 47 They are all errors of: "mod_fcgid: stderr". I tried to grep "error_log" and "error_report" in the public html dir, but i did not find anything.

• Strange Upload Problem on Hyper-V

  - by Ring0

  Hi, This one is driving me totally nuts. I have being trying to upload a file to www.virustotal.com (its a harmless exe I have since found out - DiskWipe.exe from diskwipe.org). Using IE8. From Win 7 and Win 2008 R2 Datacenter (which I select to boot from vhd's) onto my main machine hardware, and also on another Win 7 PC elsewhere on my network, when I upload the file to virustotal.com it works perfectly. So, using my native NIC's everything is fine. Using another machine also perfect. Right. OK, from my boot menu the default is my main development machine - the one I'm typing on now. This runs on the metal and has Hyper-V role and I have some guests. All guests are not running. Amazingly, from my console (root partition to be exact) or any guest OS 2003 /XP / 2008 R2 etc. My upload to virustotal.com slows at 32% then HANGS at 38.something% & never finishes!! Here is the kicker. I have another box (my main server) running Hyper-V on the metal and three live guests. Identical H/W to my main dev machine in another room. (Except OS is Datacenter - Mine is Enterprise). If I try and upload from its bare metal console or any guest this file to virustotal.com using IE8 it stops exactly in the same place!! As for "steps I have tried etc." are kind-of blown out of the water as my server box is doing the precise same thing as the machine in my room here. OK, comonalities: Mobo: Gigabyte GA-X58-UD5, 12GB Kingston RAM, Corei7 920 4 cores hyperthreading = 8 & Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC's. All 3 machines have this same motherboard - revision F11 Bios, all have 12GB RAM, all have the Realtek Nic's. All x64 by the way as I mentioned before I have a Win 7 box also with the UD5 m/Board, 12 GB RAM - bit of an overkill. :-) All these machines when NOT running Hyper-V can upload this file. Perhaps you may like to try it on a Hyepr-v (2008 R2) yourselves with IE8 and the desktop experience is on. See if it works or fails for you. Root OS or any guest. So, looking like its the NIC + Hyper-V = Cannot upload this file (any file I must add.) Realtek Nic is Ver 7.002.1125.2008. Using IE8 I see in the nic settings there are the usual parameters for Jumbo frames / Checksum offloading etc. several others. Should I fiddle with these? I ran Netmon 3.3 in a guest and the TCP session halted as the upload failed. I suppose I could study that further. I dont have Netmon on the root partition machine (yet)! All OS's fully patched - including todays defender files. My box running Office 2007 - but identical server in another room is not. Also, if I fire up a VPN to a distant client and do the upload it works! Of course its a different network path. Suggestions welcome please. If I left out anything important - please yell at me. Many Thanks,

• Outlook 2013 keeps freezing, semi-consistently

  - by AviD

  I have an oddity of problem with my Outlook's stability. It seems to be freezing up, not at random intervals, but based on a seemingly strange combination of configurations. I have been trying many different combinations, I've even devolved to "Cargo-cult" debugging, since I have no clue what is causing this... Here is my set up - since I don't know for sure which settings are causing the lockup, I'll probably mention irrelevant things: (relatively) clean install of Windows 8 (on hyper-v, if that matters) Clean install of Outlook 2013, fully updated 3 accounts configured: Hotmail account configured with ActiveSync Gmail account Large-ish account (several GB) connected with IMAP Only a few folders are subscribed in IMAP Outlook is set to only display subscribed folders configured to keep messages permanently Google Apps account, connected with IMAP Small account connected with IMAP All folders IMAP subscribed Outlook is set to only display subscribed folders configured to keep messages permanently Several Send/Receive Groups configured, to try different configurations of enabling/disable/partial the different accounts - with different send times, from 60 minutes down to 5 minutes. The problem is that at certain points Outlook completely freezes up and I have to kill it. This is not consistent - there are some things that cause it immediately almost consistently, there are some times that it just happens by itself after some period of time (sometimes a few moments, sometimes a few hours; sometimes while using it, sometimes after I've been away from it for a few hours). I have searched all over, and there seem to be many with similar (apparently) problem, and found numerous "solutions" (some even more cargocultish than mine), but so far none of them worked. I've removed all the accounts, both all together and one at a time, and re-configured them - eventually it freezes up. I've tried uninstalling Outlook, cleaning it up completely - removing files, app settings, registry keys, etc - then reinstalling - eventually it freezes up. I've only enabled the Hotmail account, disabling (but not removing) the Google accounts - apparently this does not lock up. I've enabled the Hotmail and the Gmail accounts, leaving the Apps one disabled - it seems like it does not lock up. With all accounts enabled, it locks up almost immediately after doing a send/receive. With only the Apps account enabled, it seems to not lock up. With the Hotmail and the Apps accounts enabled (Gmail disabled), it seems like it locks up after a random amount of time. With Hotmail enabled, and Gmail and Apps both enabled but set to receive only custom folder downloading (not all subscribed folders) - sometimes it locks up right after a send/receive, sometimes it goes for hours without locking up, and sometimes it only locks up when I send an email. I've tried switching the ports for the Google accounts (SSL/465 vs TLS/587), though I have no idea if this should affect, but no real difference. In short, I honestly have no idea what is actually causing Outlook to lock up, I might be completely barking up the wrong tree. At this point I don't really know what else to try, I'm flipping switches at random here. I would like to have all 3 accounts enabled, ideally in several groups (e.g. pull down only important folders in a group with short interval, and all other folders in a longer interval) - obviously without freezing up at all. I've tried putting in all the important details, if there is anything else important to add please let me know. Another issue that occurred to me might also be connected - the Google accounts don't always synchronize properly, even after a send/receive or "update folder". At least not consistently... though I haven't been able to find a significant connection between this and that.

• PHP.ini does not load

  - by Jonathan Park

  Ok this is probably just me not knowing enough about php but here it goes. I'm on Ubuntu Hardy. I have a custom compiled version of PHP which I have compiled with these parameters. ./configure --enable-soap --with-zlib --with-mysql --with-apxs2=[correct path] --with-config-file-path=[correct path] --with-mysqli --with-curlwrappers --with-curl --with-mcrypt I have used the command pecl install pecl_http to install the http.so extension. It is in the correct module directory for my php.ini. My php.ini is loading and I can change things within the ini and effect php. I have included the extension=http.so line in my php.ini. That worked fine. Until I added these compilation options in order to add imap --with-openssl --with-kerberos --with-imap --with-imap-ssl Which failed because I needed the c-client library which I fixed by apt-get install libc-client-dev After which php compiles fine and I have working imap support, woo. HOWEVER, now all my calls to HttpRequest which is part of the pecl_http extention in http.so result in Fatal error: Class 'HttpRequest' not found errors. I figure the http.so module is no longer loading for one reason or another but I cannot find any errors showing the reason. You might say "Have you tried undoing the new imap setup?" To which I will answer. Yes I have. I directly undid all my config changes and uninstalled the c-client library and I still can't get it to work. I thought that's weird... I have made no changes that would have resulted in this issue. After looking at that I have also discovered that not only is the http extension no longer loading but all my extensions loaded via php.ini are no longer loading. Can someone at least give me some further debugging steps? So far I have tried enabling all errors including startup errors in my php.ini which works for other errors, but I'm not seeing any startup errors either on command line or via apache. And yet again the php.ini appears to be being parsed given that if I run php_info() I get settings that are in the php.ini. Edit it appears that only some of the php.ini settings are being listened to. Is there a way to test my php.ini? Edit Edit It appears I am mistaken again and the php.ini is not being loaded at all any longer. However, If I run php_info() I get that it's looking for my php.ini in the correct location. Edit Edit Edit My config is at the config file path location below but it says no config file loaded. WTF Permission issue? It is currently 644 so everyone should be able to read it if not write it. I tried making it 777 and that didn't work. Configuration File (php.ini) Path /etc/php.ini Loaded Configuration File (none) Edit Edit Edit Edit By loading the ini on the command line using the -c command I am able to run my files and using -m shows that my modules load So nothing is wrong with the php.ini

• Transparent proxy which preserves client mac address

  - by A G

  I have a customer that wants to intercept SSL traffic as it leaves their network. My proposed solution is to setup a proxy that is transparent and both layer 2 and layer 3 so it can simply be dropped into their network without any change in config required. The proxy has two NICs, one connected to the server, the other to the client. The client, proxy and gateway are under control of the customer, the server is not. For example: client --- Proxy --- gateway -|- server I have my proxy program configured with IP_TRANSPARENT socket option to it can respond to connections destined for a remote IP. I am using the following setup: iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --on-port 3128 --tproxy-mark 1/1 iptables -t mangle -A PREROUTING -p tcp -j MARK --set-mark 1 ip rule add fwmark 1/1 table 1 ip route add local 0.0.0.0/0 dev lo table 1 The client in question is on its own subnet and has been configured so that the proxy is the default gateway. The result is: Client sends a frame to the proxy; source IP is client, source mac is client, destination IP is server, destination mac is proxy Proxy forwards this frame to the gateway; source IP is proxy, source mac is proxy, destination IP is server, destination mac is gateway Gateway forwards this to the server and gets a response back. Gateway sends reply back to proxy; source IP is server, source mac is gateway, destination IP is proxy, destination mac is proxy Proxy forwards this reply to client; source IP is server, source mac is proxy, destination IP is client, destination mac is client. The tproxy and iptables configuration lets the proxy send packets with a non local ip address. Is there a way to make something transparent at the mac address level? That is, put the client on the same subnet as the gateway. The gateway sees the source IP and mac as that of the client, even though they originated from the proxy. Could this be done by configuring the proxy as a bridge then use ebtables to escalate the traffic to be handled by iptables? When I use ebtables to push something up to iptables, it appears my proxy program doesn't respond to the packets as they are destined for the gateways's mac address, not the proxy's. What are some other potential avenues I could investigate? EDIT: When the client and gateway are on different subnets (and client has set the proxy as the gateway), it works as described in 1 to 5. But I want to know if it is possible to have the client and gateway on the same subnet and have the proxy fully transparent (ie client is not aware of the proxy). Thanks! EDIT 2: I can configure the proxy as a bridge using brctl, but cannot find a way to direct this traffic to my proxy program - asked here Possible for linux bridge to intercept traffic?. Currently, with the description numbered 1 to 5, it operates at layer 3; it is transparent on the client side (client thinks it is talking to the server's IP), but not on the gateway side (gateway is talking to the proxy's IP). What I want to find out is, is it possible to make this operate at layer 2, so it is fully transparent? What are the available options I should research? Thanks
