• Malicious content on server - next steps advice [closed]

  - by Under435

  Possible Duplicate: My server's been hacked EMERGENCY I just got an e-mail from my hosting company that they got a report of malicious content being hosted on my vps. I was unaware of this and started looking into it. I discovered a file called /var/www/mysite.com/osc.htm. Soon after I discovered some weird php files wp-includes.php and ndlist.php both recognized as being PHP/WebShell.A.1 virus. I removed all these files but I'm unsure of what to do next. Can anyone help me analyze the output below of sudo netstat -A inet -p -e and give advice on what's best to do next.

• Iptables rules, forward between two interfaces

  - by Marco

  i have a some difficulties in configuring my ubuntu server firewall ... my situation is this: eth0 - internet eth1 - lan1 eth2 - lan2 I want that clients from lan1 can't communicate with clients from lan2, except for some specific services. E.g. i want that clients in lan1 can ssh into client in lan2, but only that. Any other comunication is forbidden. So, i add this rules to iptables: #Block all traffic between lan, but permit traffic to internet iptables -I FORWARD -i eth1 -o ! eth0 -j DROP iptables -I FORWARD -i eth2 -o ! eth0 -j DROP # Accept ssh traffic from lan1 to client 192.168.20.2 in lan2 iptables -A FORWARD -i eth1 -o eth2 -p tcp --dport 22 -d 192.168.20.2 -j ACCEPT This didn't works. Doing iptables -L FORWARD -v i see: Chain FORWARD (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 33 144 DROP all -- eth1 !eth0 anywhere anywhere 0 0 DROP all -- eth2 !eth0 anywhere anywhere 23630 20M ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED 0 0 ACCEPT all -- eth1 any anywhere anywhere 175 9957 ACCEPT all -- eth1 any anywhere anywhere 107 6420 ACCEPT all -- eth2 any anywhere anywhere 0 0 ACCEPT all -- pptp+ any anywhere anywhere 0 0 ACCEPT all -- tun+ any anywhere anywhere 0 0 ACCEPT tcp -- eth1 eth2 anywhere server2.lan tcp dpt:ssh All packets are dropped, and the count of packets for the last rule is 0 ... How i have to modify my configuration? Thank you. Regards Marco

• Under what conditions will sendmail try to immediately resend a message instead of waiting for the standard requeue interval?

  - by Mike B

  CentOS 5.8 | Sendmail 8.14.4 I used to think that if SendMail experienced a temporary (400-class) error during delivery, it would place the message in a deferred queue (e.g. /var/spool/mqueue) and retry an hour later. For the most part, that appears to be the case. But every now and then, I'll notice log entries like this (email/domains renamed to protect the innocent :-) ) : Dec 5 01:43:03 foobox-out sendmail [11078]: qBE3l7js123022: to=<[email protected]>, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=124588, relay=exbox.foo.com. [10.10.10.10], dsn=4.0.0, stat=Deferred: 421 4.3.2 The maximum number of concurrent connections has exceeded a limit, closing transmission channel Dec 5 01:53:34 foobox-out sendmail [12763]: qBE3l7js123022: to=<[email protected]>, delay=00:10:31, xdelay=00:00:00, mailer=relay, pri=214588, relay=exbox.foo.com., dsn=4.0.0, stat=Deferred: 452 4.3.1 Insufficient system resources Dec 5 02:53:35 foobox-out sendmail [23255]: qBE3l7js123022: to=<[email protected]>, delay=01:10:32, xdelay=00:00:01, mailer=relay, pri=304588, relay=exbox.foo.com. [10.10.10.10], dsn=2.0.0, stat=Sent (<[email protected]> Queued mail for delivery) Why did Sendmail try again just 10 minutes after the first attempt and then wait another hour before trying again? If this is expected behavior, what scenarios will cause this faster requeue interval to occur?

• Trouble connecting to a local SQL server instance from the web

  - by dfarney

  We have a small network behind a firewall (WatchGuard XTM 2 series) and network switch. On our network we have multiple instances of SQL server, but 1 in specific that I would like to be able to access remotely from our website. We have a static IP address from our ISP and then all the machines on the network have a locally assigned dynamic IP address. When trying to connect to the database from outside our network how do I get the request to be directed to the proper machine / SQL instance? Is it a parameter in my connection string or something in my firewall? A few things to rule out: 1) The firewall is allowing access from the website to our network. I added the site's IP and opened up port 1433. Also, when trying to connect and monitoring the firewall no exceptions come up as they did before I added the proper IP address. 2) Remote connections on the SQL server has been setup and enabled. I've done a lot of reading up on remote connections and I am sure it has been setup properly. I am currently getting this error message on my site: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

• Need info on scripts and Autoforward through Exchange Server in Outlook 2010

  - by user103037

  I am using the below information to auto-forward my work emails to my BB via a gmail account. The script works fine. But my work email ask's for every email to send either classifield or unclassified. What and where would I add into the below script to autoforward unclassified? I have written some VBA script to do this bypass the server's disabling of auto-forward. Basically it mimics the user forwarding the email rather than the server doing an auto-forward. It's pretty simple: Sub AutoForwardAllSentItems(Item As Outlook.MailItem) Dim strMsg As String Dim myFwd As Outlook.MailItem Set myFwd = Item.Forward myFwd.Recipients.Add "[email protected]" myFwd.Send Set myFwd = Nothing End Sub It's beyond the scope of this post to give detailed instructions, but here's a summary: Add the above code in the Visual Basic editor of Outlook (Alt-F11 should get your started). Be sure to change [email protected] to the address where you want the mail to go Tell Outlook to run this code for each inbound message (Tools - Rules and Alerts - New Rule - Check Messages when they arrive - Next - YES - Checkbox "Run a Script" - Then select the script you just created. Now Outlook should automatically forward each email you receive, but it won't be blocked by the Admin as an "Auto-forward".

• Can't access Port 80 from external

  - by dewacorp.alliances

  Hi there I have configuration like this: NETGEAR MODEM LINKSYS ROUTER SERVERS In the modem, I've setup as bridging and all the traffic is controlling by this ROUTER. Prior to this setup, I can access website from external (port 80) plus exchange servers (mail) and https. But now with this configuration, I can only send/receive using Exhcange servers and access OWA (Outlook web access using port 443) .... and no internal websites from outside. This is my config for LINKSYS ROUTER Application | Start | End | Protocol | IP Address Ms Exchange | 25 | 25 | Both (TCP/UDP) | 192.168.100.8 Internets | 80 | 80 | Both (TCP/UDP) | 192.168.100.11 SSL | 443 | 443 | Both (TCP/UDP) | 192.168.100.8 Exchange | 110 | 110 | Both (TCP/UDP) | 192.168.100.8 192.168.100.11 is a UBUNTU web server that running the apache which controlling the virtual name (extranet, cms, test) to redirect to the different servers. As you can see, the home internet is only allowing public IP address. Now I test this schenarion in internal network work nicely. For instance. If I type in extranet.XXX.local it goes to the right applicatios or if I try CMS.XXX.local again it goes to the right one. I also asked to ISP just in case if they are blocking the inbound port 80 for unknown reason. They said no. So I didn't understand why this happens. I suspect the configuration that I have between MODEM ROUTER but I counldn't work what it is. I don't have a documentation of previous settings and I don't know if there is a port that I need to open as well. I am appreciated your comment

• IP tables blocking access to most hosts but some accesses being logged

  - by epo

  What am I getting wrong? A while back I locked down my web hosting service while hardening it or at least trying to. Apache listens on port 80 only and I set up iptables using the following: IPS="list of IPs" iptables --new-chain webtest # Accept all established connections iptables -A INPUT --protocol tcp --dport 80 --jump webtest iptables -A INPUT --match state --state ESTABLISHED,RELATED --jump ACCEPT iptables -A webtest --match state --state ESTABLISHED,RELATED --jump ACCEPT for ip in $IPS; do iptables -A webtest --match state --state NEW --source $ip --jump ACCEPT done iptables -A webtest --jump DROP However looking at my apache logs I notice various log entries in access_log, e.g. 221.192.199.35 - - [16/May/2010:13:04:31 +0100] "GET http://www.wantsfly.com/prx2.php?hash=926DE27C156B40E55E4CFC8F005053E2D81E6D688AF0 HTTP/1.0" 404 206 "-" "Mozilla/ 4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 201.228.144.124 - - [16/May/2010:11:54:16 +0100] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 226 "-" "-" 207.46.195.224 - - [16/May/2010:04:06:48 +0100] "GET /robots.txt HTTP/1.1" 200 311 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)" How are these slipping through? I don't mind the indexing bots (though I am a little surprised to see them get through). I suppose they must be getting through using the ESTABLISHED,RELATED rules. And no, I can't for the life of me remember why the first match state rule is there So 2 questions: is there a better way to set up iptables to restrict access to specified hosts? How exactly are these 3 examples slipping through?

• Configure Apache + Passenger to serve static files from different directory

  - by Rory Fitzpatrick

  I'm trying to setup Apache and Passenger to serve a Rails app. However, I also need it to serve static files from a directory other than /public and give precedence to these static files over anything in the Rails app. The Rails app is in /home/user/apps/testapp and the static files in /home/user/public_html. For various reasons the static files cannot simply be moved to the Rails public folder. Also note that the root http://domain.com/ should be served by the index.html file in the public_html folder. Here is the config I'm using: <VirtualHost *:80> ServerName domain.com DocumentRoot /home/user/apps/testapp/public RewriteEngine On RewriteCond /home/user/public_html/%{REQUEST_FILENAME} -f RewriteCond /home/user/public_html/%{REQUEST_FILENAME} -d RewriteRule ^/(.*)$ /home/user/public_html/$1 [L] </VirtualHost> This serves the Rails application fine but gives 404 for any static content from public_html. I have also tried a configuration that uses DocumentRoot /home/user/public_html but this doesn't serve the Rails app at all, presumably because Passenger doesn't know to process the request. Interestingly, if I change the conditions to !-f and !-d and the rewrite rule to redirecto to another domain, it works as expected (e.g. http://domain.com/doesnt_exist gets redirected to http://otherdomain.com/doesnt_exist) How can I configure Apache to serve static files like this, but allow all other requests to continue to Passenger?

• how to rewrite '%25' in url

  - by nn4l

  My website software replaces space characters with '+' characters in the URL, A proper link would look like 'http://www.schirmacher.de/display/INFO/How+to+reattach+a+disk+to+XenServer' for example. Some websites link to that article but somehow their embedded editor can't handle the encoding, so what I see in the httpd log files is actually GET /display/INFO/How%2525252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer which of course leads to a 404 error. It seems that the '+' character is encoded as '%2b' and then the '%' character is encoded as '%25' - several times. Since there are many such references to different pages from different websites, I would like to rewrite the url so that the visitors get the correct page. Here's my attempt which does not work: RewriteRule ^(.*)%25(.*)$ $1%$2 [R=301] What it is supposed to do is: take everything before the %25 string and everything after it, concat those strings with a '%' in between, then redirect. With the example input URL the rule should rewrite to /display/INFO/How%25252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer followed by a redirect, then it should rewrite to /display/INFO/How%252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer and again to /display/INFO/How%2bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer and so on. Finally, after a lot of redirects I should have left /display/INFO/How%2bto%2breattach%2ba%2bdisk%2bto%2bXenServer which is a valid url equivalent to /display/INFO/How+to+reattach+a+disk+to+XenServer. My problem is that the expression does not match at all, so it does not even replace a single occurrence of %25. I understand that there is a limit in the number of redirects and I should really use the [N] flag however I don't even get the first step right.

• Problem with Outlook 2010 (SMTP AUTH LOGIN)

  - by Filipe YaBa Polido

  I have to connect one customer Outlook 2010 to a remote server on which I have either no right, neither way to talk to the sysadmin. This is the thing, after installing and reviewing the logs on Wireshark: Outlook Express: HELO machine AUTH LOGIN username base64 encoded password base64 encoded mails go through. Outlook 2010: HELO machine AUTH DIGEST-MD5 response from server Outlook sends just a * AUTH LOGIN password base64 encoded So... I can send mails in the same domain, but can't send outside, it gives me a relay denied message. My point is... Why the h**l Outlook 2010 doesn't send the username AND the password?! It can never login the right way :| With other versions of Outlook it works fine, and with OE works great, it auths and allows to send mail to a different domain. I've googled and nothing worked. I'm pretty sure that I'm not alone with this one. My last resort will be to configure a local proxy/server that relays to the original one :| Any help would be appreciated. Sorry my bad english as is not my natural language. Thanks.

• How to configure traffic from a specific IP hardcoded to an IP to forward to another IP:PORT using i

  - by cclark

  Unfortunately we have a client who has hardcoded a device to point at a specific IP and port. We'd like to redirect traffic from their IP to our load balancer which will send the HTTP POSTs to a pool of servers able to handle that request. I would like existing traffic from all other IPs to be unaffected. I believe iptables is the best way to accomplish this and I think this command should work: /sbin/iptables -t nat -A PREROUTING -s $CUSTIP -j DNAT -p tcp --dport 8080 -d $CURR_SERVER_IP --to-destination $NEW_SERVER_IP:8080 Unfortunately it isn't working as expected. I'm not sure if I need to add another rule, potentially in the POSTROUTING chain? Below I've substituted the variables above with real IPs and tried to replicate the layout in my test environment in incremental steps. $CURR_SERVER_IP = 192.168.2.11 $NEW_SERVER_IP = 192.168.2.12 $CUST_IP = 192.168.0.50 Port forward on the same IP /sbin/iptables -t nat -A PREROUTING -p tcp -d 192.168.2.11 --dport 16000 -j DNAT --to-destination 192.168.2.11:8080 Works exactly as expected. IP and port forward to a different machine /sbin/iptables -t nat -A PREROUTING -p tcp -d 192.168.2.11 --dport 16000 -j DNAT --to-destination 192.168.2.12:8080 Connections seem to timeout. Restrict IP and port forward to only be applied to requests from a specific IP /sbin/iptables -t nat -A PREROUTING -p tcp -s 192.168.0.50 -d 192.168.2.11 --dport 16000 -j DNAT --to-destination 192.168.2.12:8080 Times out as well. Probably for the same reason as the previous entry. Does anyone have any insights or suggestions? thanks,

• Compressing and copying large files on Windows Server?

  - by Aaron

  I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

• Links break in IE9 when using Wordpress plugins in non Wordpress Page

  - by mouli

  I have a site that uses SEF URLs and htaccess RewriteRules to serve up the pages. This has worked fine for several years until the arrival of IE9. Now it appears that the links are not being rewritten and the site is dead in the water. I have tried different compatabilty modes, to no avail, and I've played with the Rewrite Rules over and over, tried different doctypes and a few other browser settings. I agree that it cannot in theory be a browser specific problem if the problem is with the htaccess file but this site works in IE8, firefox and chrome. I have run the rewriterule through a validator and it looks fine. Any ideas would be appreciated as I am running out of ideas. The site is www.marlboroughsounds.co.nz a sample link is http://www.marlboroughsounds.co.nz/walking/freedom-walk-queen-charlotte-track/4dfw and the rewrite rule thats not working looks like this: RewriteRule ^walking/.*/([a-z0-9_]*)/?$ /walking.php?act_code=$1 [L] The link fails and it serves up a browser 404 page, not even the custom 404 I have for the site. Any ideas would be much appreciated as I am stumped.

• keyboard intermittently stops working, even after reinstalling windows 7; possibly a Chrome issue?

  - by neverskipbreakfast

  My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash a couple of the ctrl+alt+windows type keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu, but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) *Unplugging & reconnecting keyboard does NOT fix it. *Connecting a different keyboard does NOT fix it. That one won't work, either. *Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. *Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears, they keyboard won't work, and neither will the icon to pull up the on-screen keyboard. Otherwise my mouse can click around just fine. I can only log onto a non-password protected account. *Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. *Clearing my Chrome browsing data stopped the problem from recurring for a week or so. *I use Avira free antivirus software, and repeated scans turn up nothing fishy. *I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. The only thing I suspect is something in Google Chrome -- I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?

• Redirection of outbound UDP port NTP.

  - by pboin

  For my residential service, I changed ISPs to Zoom/Armstrong. Just after that, my NTP daemons stopped working. I dug deep and diagnosed the problem: Unprivileged ports are getting out. When i run 'ntpdate' for example, I go out on a high, unprivleged port, and get a response on UDP 123. That's fine. The 'ntpd' daemon though, expects to go out on 123 and get its reply there as well. This must be a common problem, because it's directly addressed in the NTP troubleshooting guide. Just to see what would happen, I wrote a detailed email to the general support address at Armstrong. They replied almost immediately with a complete technical answer! They have everything <1024 blocked, except for a few ports to support outbound VPN. So, the question: Can I use IPtables to essentially re-write my outbound UDP 123 up to 2123 or something like that? If I do, does there need to be a corresponding 2123-123 rule to translate the reply? This seems like NAT, but with ports, not addresses. True, I could run ntpdate from cron, but that loses all of the adjustment smarts of NTP.

• What's wrong with my .htaccess? Trying to simplify actual code

  - by AlexV

  This is my actual .htaccess: #If the requested URI does not end with an extension RewriteCond %{REQUEST_URI} !\.(.*) #If the requested URI is not in an excluded location RewriteCond %{REQUEST_URI} !^/(excluded1|excluded2)/ #Then serve the URI via the mapper RewriteRule .* /seo-urls/seo-urls-mapper.php?uri=%{REQUEST_URI} [L,QSA] #If the requested URI ends with .php* RewriteCond %{REQUEST_URI} \.php.*$ [NC] #If the requested file is not seo-urls-mapper.php (avoid .htaccess loop) RewriteCond %{REQUEST_FILENAME} (?<!seo-urls-mapper)\.php.*$ #Then serve the URI via the mapper RewriteRule .* /seo-urls/seo-urls-mapper.php?uri=%{REQUEST_URI} [L,QSA] Since all conditions are compatibles except the 1st ones (no extension and *.php* match) all I should have to do is to add the [OR] condition to these 2 lines, but when I'm adding it it's not working (my no extension rule don't work anymore). This is my new (not working) code: #If the requested URI does not end with an extension OR if the URI ends with .php* RewriteCond %{REQUEST_URI} !\.(.*) [OR] RewriteCond %{REQUEST_URI} \.php.*$ [NC] #If the requested file is not seo-urls-mapper.php (avoid .htaccess loop) RewriteCond %{REQUEST_FILENAME} (?<!seo-urls-mapper)\.php.*$ #If the requested URI is not in an excluded location RewriteCond %{REQUEST_URI} !^/(excluded1|excluded2)/ #Then serve the URI via the mapper RewriteRule .* /seo-urls/seo-urls-mapper.php?uri=%{REQUEST_URI} [L,QSA] Hopefully someone will be able to clarify this issue... I guess I don't fully understand the use of [OR]. Thanks!

• Simple vLAN setup

  - by Logan Bissonnette

  I have a basic lab environment set up to try and get 2 vLANs working in hyper-v. I have the following equipment 1 hyper-v server 1 Desktop PC 1 Managed Switch (d-link DES-3052P) 1 cheap router (DI-604) My end goal is to have 1 VM and the desktop on one vLAN with internet, and 1 VM on a separate vLAN with internet access. I am having troubles getting an internet connection to both vLANs. The switch does not have the ability to have asynchronous vLANs. This is my switch configuration Port 1 - Trunk Port - Connected to router Port 2 - Trunk Port - Connected to hyper-v Server Port 3 - Access Port- Connected to Desktop Within hyper-v I have 1 switch and 2 VMs. When the VMs are set up to use vlan ID 1, everything works fine. As soon as a VM is set up to use vlan ID 2, they lose all network connection and cannot communicate with the router anymore. I believe this is because the router is not vLAN aware. Can anyone help me with what settings need to be set up on my switch? I believe I want an egress rule so traffic leaving towards the router is untagged, is that right? If not, any ideas or hints as to what needs to be set up?

  I am building an application tshirtshop I have following configuration in /etc/apache2/sites-enabled/tshirtshop <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www/tshirtshop <Directory /var/www/tshirtshop> Options Indexes FollowSymLinks AllowOverride All Order allow,deny allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> and following in .htaccess file in location /var/www/tshirtshop/.htaccess <IfModule mod_rewrite.c> # Enable mod_rewrite RewriteEngine On # Specify the folder in which the application resides. # Use / if the application is in the root. RewriteBase /tshirtshop #RewriteBase / # Rewrite to correct domain to avoid canonicalization problems # RewriteCond %{HTTP_HOST} !^www\.example\.com # RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L] # Rewrite URLs ending in /index.php or /index.html to / RewriteCond %{THE_REQUEST} ^GET\ .*/index\.(php|html?)\ HTTP RewriteRule ^(.*)index\.(php|html?)$ $1 [R=301,L] # Rewrite category pages RewriteRule ^.*-d([0-9]+)/.*-c([0-9]+)/page-([0-9]+)/?$ index.php?DepartmentId=$1&CategoryId=$2&Page=$3 [L] RewriteRule ^.*-d([0-9]+)/.*-c([0-9]+)/?$ index.php?DepartmentId=$1&CategoryId=$2 [L] # Rewrite department pages RewriteRule ^.*-d([0-9]+)/page-([0-9]+)/?$ index.php?DepartmentId=$1&Page=$2 [L] RewriteRule ^.*-d([0-9]+)/?$ index.php?DepartmentId=$1 [L] # Rewrite subpages of the home page RewriteRule ^page-([0-9]+)/?$ index.php?Page=$1 [L] # Rewrite product details pages RewriteRule ^.*-p([0-9]+)/?$ index.php?ProductId=$1 [L] </IfModule> the site is working on localhost and is working as if there is no .htaccess rule specified i.e. if I were to view a page as http://localhost/tshirtshop/nature-d2 then I get a 404 Error but if I view the same page as http://localhost/tshirtshop/index.php?DepartmentId=2 then I can view it.

• Apache 2.4 with PHP-FPM

  - by tubaguy50035

  I'm trying to setup Apache 2.4 with PHP-FPM 5.4 using the new modules with Apache 2.4. The following is what I have currently in my virtual host file: <VirtualHost *:80> ServerAdmin root@localhost DocumentRoot /var/www #Directory permissions <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Require all granted </Directory> CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> I have PHP-FPM running using Unix sockets with a sock file located at /var/run/php5-fpm.sock. How do I proxy my requests to this sock file? I've seen some sites say to use ProxyPassMatch and others are saying Rewrite Rule. Are there pros or cons on either side? Also, most sites I'm seeing are showing ProxyPassMatch with a regex to only pass .php files. Could I also send it .html files? For whatever reason, we have a ton of PHP inside .html files. Edit: As noted in the comments, it looks like mod_proxy_fcgi doesn't support Unix sockets. Is there another module I should be using?

• Configuring postfix with Gmail

  This is what I did.. sudo apt-get install postfix This is my /etc/postfix/main.cf: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

• Can varnish cache files without specific extension or residing in specific directory

  - by pataroulis

  I have a varnish installation to cache (MANY) images that my service serves. It is about 200 images of around 4k per second and varnish happily serves them according to the following rule: if (req.request == "GET" && req.url ~ "\.(css|gif|jpg|jpeg|bmp|png|ico|img|tga|wmf)$") { remove req.http.cookie; return(lookup); } Now, the thing is that I recently added another service on the same server that creates thumbnails to serve but it does not add a specific extension. The files are of the following filename pattern: http://www.example.com/thumbnails/date-of-thumbnail/xxxxxxxxx.xx where xx are numbers, so xxxxxxxxx.xx could be 6482364283.73 (two numbers at the end) (actually this is the timestamp so I can keep extra info in the filename) That has the side effect that varnish does not cache them and I see them constantly being served by apache itself. Even though I can change the format from now on to create thumbs ending in .jpg, is there a way to change the vcl file of my varnish daemon to either cache everything under a directory (the thumbnails directory) or everything with two numbers at its extension? Let me know if I can provide any additional info ! Thanks!

• Postfix additional transports - is it working?

  - by threecheeseopera

  I have enabled two additional transports in my postfix config to deal with recipient domains that demand connection limiting, per the instructions here at serverfault. However, I have no idea if this is working or not; in fact, I think it is not working, due to the send speeds I am seeing in the logs. How might I determine if my additional transports are working? If they aren't, do you have any tips on figuring out why? And, do you have any comments on my particular configuration? (am I a bucket of fail?) I have enabled the additional transports in master.cf: smtp inet n - - - - smtpd careful unix - - n - 10 smtp -o smtp_connect_timeout=5 -o smtp_helo_timeout=5 cautious unix - - n - - smtp -o smtp_connect_timeout=5 -o smtp_helo_timeout=5 I have set up the transport mapping file /etc/postfix/transport: hotmail.com cautious: yahoo.com careful: gmail.com cautious: earthlink.net cautious: msn.com cautious: live.com cautious: aol.com careful: I have set up the transport mapping and some connection-limiting settings in main.cf: transport_maps = hash:/etc/postfix/transport careful_initial_destination_concurrency = 5 careful_destination_concurrency_limit = 10 cautious_destination_concurrency_limit = 50 Finally, I have run converted the transport file to a db per the postfix docs: #> postmap /etc/postfix/transport And then restarted postfix. I do see my transport_maps setting when I run postconf, but I do not see any of the transport-specific settings ('careful_xxx_yyy_zzz'). Also the mail logs do not appear to be different in any way to what they were previously. Thanks!!!

• Linux port-based routing using iptables/ip route

  - by user42055

  I have the following setup: 192.168.0.4 192.168.0.6 192.168.0.1 +-----------+ +---------+ +----------+ |WORKSTATION|------| LINUX |------| GATEWAY | +-----------+ +---------+ +----------+ 192.168.150.10 | 192.168.150.9 +---------+ | VPN | +---------+ 192.168.150.1 WORKSTATION has a default route of 192.168.0.6 LINUX has a default route of 192.168.0.1 I am trying to use the gateway as the default route, but route port 80 traffic via the VPN. Based on what I read at http://www.linuxhorizon.ro/iproute2.html I have tried this: echo "1 VPN" >> /etc/iproute2/rt_tables sysctl net.ipv4.conf.eth0.rp_filter = 0 sysctl net.ipv4.conf.tun0.rp_filter = 0 sysctl net.ipv4.conf.all.rp_filter = 0 iptables -A PREROUTING -t mangle -i eth0 -p tcp --dport 80 -j MARK --set-mark 0x1 ip route add default via 192.168.150.9 dev tun0 table VPN ip rule add from all fwmark 0x1 table VPN When I run "tcpdump -i eth0 port 80" on LINUX, and open a webpage on WORKSTATION, I don't see the traffic go through LINUX at all. When I run a ping from WORKSTATION, I get this back from some packets: 92 bytes from 192.168.0.6: Redirect Host(New addr: 192.168.0.1) Vr HL TOS Len ID Flg off TTL Pro cks Src Dst 4 5 00 0054 de91 0 0000 3f 01 4ed3 192.168.0.4 139.134.2.18 Is this why my routing is not working ? Do I need to put GATEWAY and LINUX on different subnets to prevent WORKSTATION being redirected to GATEWAY ? Do I need to use NAT at all, or can I do this with routing alone (which is what I want) ?

• Exchange 2003 -- Mailbox Management not deleting ALL messages aged 30 days or older...

  - by tcv

  I've recently created a Mailbox Management task within Exchange 2003 that, every night, looks at the contents of the Deleted Items within a particular mailbox and deletes mail that's 30 days or older. The scheduled task ran on its own last night and I have confirmed that messages within the right mailbox and the right folder were, in fact, processed. Many mails were deleted ... but not never email older than 30 days. In fact, the choice seems kinda random. Last night 3/10/2010 was the 30 day watermark. Mails were deleted from 3/10/2010, sure enough, but not all of them. Mails older than 3/10/2010 were deleted as well, but, again, not all of them. The only criteria I have on the management -- aside from the single mailbox and single folder scopes -- is the age criteria. The size criteria is set to Any, meaning I don't care about the size. I care about the age. It's made me wonder where there is some sort of limit on how many mails can be processed? The schedule is set for 12am and 1am every night. Any hints appreciated.
