Magento hosting on a budget

- by spa

I have to do a setup for Magento. My constraint is primarily ease of setup and fault tolerance/fail over. Furthermore costs are an issue. I have three identical physical servers to get the job done. Each server node has an i7 quad core, 16GB RAM, and 2x3TB HD in a software RAID 1 configuration. Each node runs Ubuntu 12.04. right now. I have an additional IP address which can be routed to any of these nodes. The Magento shop has max. 1000 products, 50% of it are bundle products. I would estimate that max. 100 users are active at once. This leads me to the conclusion, that performance is not top priority here. My first setup idea One node (lb) runs nginx as a load balancer. The additional IP is used with domain name and routed to this node by default. Nginx distributes the load equally to the other two nodes (shop1, shop2). Shop1 and shop2 are configured equally: each server runs Apache2 and MySQL. The Mysqls are configured with master/slave replication. My failover strategy: Lb fails = Route IP to shop1 (MySQL master), continue. Shop1 fails = Lb will handle that automatically, promote MySQL slave on shop2 to master, reconfigure Magento to use shop2 for writes, continue. Shop2 fails = Lb will handle that automatically, continue. Is this a sane strategy? Has anyone done a similar setup with Magento? My second setup idea Another way to do it would be to use drbd for storing the MySQL data files on shop1 and shop2. I understand that in this scenario only one node/MySQL instance can be active and the other is used as hot standby. So in case shop1 fails, I would start up MySQL on shop2, route the IP to shop2, and continue. I like that as the MySQL setup is easier and the nodes can be configured 99% identical. So in this case the load balancer becomes useless and I have a spare server. My third setup idea The third way might be master-master replication of MySQL databases. However, in my optinion this might be tricky, as Magento isn't build for this scenario (e.g. conflicting ids for new rows). I would not do that until I have heard of a working example. Could you give me an advice which route to follow? There seems not one "good" way to do it. E.g. I read blog posts which describe a MySQL master/slave setup for Magento, but elsewhere I read, that data might get duplicated when the slave lags behind the master (e.g. when an order is placed, a customer might get created twice). I'm kind of lost here.

Is Apache 2.2.22 able to sustain 1.000 simultaneous connected clients?

- by Fnux

For an article in a news paper, I'm benchmarking 5 different web servers (Apache2, Cherokee, Lighttpd, Monkey and Nginx). The tests made consist of measuring the execution times as well as different parameters such as the number of request served per second, the amount of RAM, the CPU used, during a growing load of simultaneous clients (from 1 to 1.000 with a step of 10) each client sending 1.000.000 requets of a small fixed file, then of a medium fixed file, then a small dynamic content (hello.php) and finally a complex dynamic content (the computation of the reimbursment of a loan). All the web servers are able to sustain such a load (up to 1.000 clients) but Apache2 which always stops to respond when the test reach 450 to 500 simultaneous clients. My configuration is : CPU: AMD FX 8150 8 cores @ 4.2 GHz RAM: 32 Gb. SSD: 2 x Crucial 240 Gb SATA6 OS: Ubuntu 12.04.3 64 bit WS: Apache 2.2.22 My Apache2 configuration is as follows: /etc/apache2/apache2.conf LockFile ${APACHE_LOCK_DIR}/accept.lock PidFile ${APACHE_PID_FILE} Timeout 30 KeepAlive On MaxKeepAliveRequests 1000000 KeepAliveTimeout 2 ServerName "fnux.net" <IfModule mpm_prefork_module> StartServers 16 MinSpareServers 16 MaxSpareServers 16 ServerLimit 2048 MaxClients 1024 MaxRequestsPerChild 0 </IfModule> User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} AccessFileName .htaccess <Files ~ "^\.ht"> Order allow,deny Deny from all Satisfy all </Files> DefaultType None HostnameLookups Off ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel emerg Include mods-enabled/*.load Include mods-enabled/*.conf Include httpd.conf Include ports.conf LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent Include conf.d/ Include sites-enabled/ /etc/apache2/ports.conf NameVirtualHost *:8180 Listen 8180 <IfModule mod_ssl.c> Listen 443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> /etc/apache2/mods-available <IfModule mod_fastcgi.c> AddHandler php5-fcgi .php Action php5-fcgi /cgi-bin/php5.external <Location "/cgi-bin/php5.external"> Order Deny,Allow Deny from All Allow from env=REDIRECT_STATUS </Location> </IfModule> /etc/apache2/sites-available/default <VirtualHost *:8180> ServerAdmin webmaster@localhost DocumentRoot /var/www/apache2 <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel emerg ##### CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> <IfModule mod_fastcgi.c> AddHandler php5-fcgi .php Action php5-fcgi /php5-fcgi Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -host 127.0.0.1:9000 -pass-header Authorization </IfModule> </VirtualHost> /etc/security/limits.conf * soft nofile 1000000 * hard nofile 1000000 So, I would trully appreciate your advice to setup Apache2 to make it able to sustain 1.000 simultaneous clients, if this is even possible. TIA for your help. Cheers.

php-fpm + persistent sockets = 502 bad gateway

- by leeoniya

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

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

Unison synchronization problem. Roots are not identical after synchronization.

- by binary255

Hi. When I synchronize two folders using Unison, only one of the roots seems to be affected. Below are all the information I would think is necessary to figure out why it is working like it is. I'm using $ unison -version unison version 2.27.57 From the Ubuntu repositories. My work laptop: $ echo $UNISONLOCALHOSTNAME worklaptop $ pwd /home/userfoo $ ls -lAR .unison* .unison: total 8 drwxr-xr-x 2 userfoo userfoo 4096 2010-04-26 11:39 backups -rw-r--r-- 1 userfoo userfoo 231 2010-04-26 11:38 default.prf .unison/backups: total 0 .unisonroot: total 0 $ cat .unison/default.prf # Roots of the synchronization root = /home/userfoo/.unisonroot root = ssh://devel//home/userbar/.unisonroot path = * backuplocation = central backupdir = /home/.unison/backups backupprefix = $VERSION.bak $ mkdir .unisonroot/aDirectoryFrom-$UNISONLOCALHOSTNAME $ echo something >.unisonroot/aFileFrom-$UNISONLOCALHOSTNAME $ ls .unisonroot/ aDirectoryFrom-worklaptop aFileFrom-worklaptop And the Ubuntu server I want to synchronize with: $ echo $UNISONLOCALHOSTNAME workcmpuserbardevel $ pwd /home/userbar $ ls -lAR .unison* .unison: total 4 drwxr-xr-x 2 userbar userbar 4096 2010-04-26 11:38 .unison .unison/.unison: total 0 .unisonroot: total 0 $ mkdir .unisonroot/aDirectoryFrom-$UNISONLOCALHOSTNAME $ echo something >.unisonroot/aFileFrom-$UNISONLOCALHOSTNAME $ ls .unisonroot/ aDirectoryFrom-workcmpuserbardevel aFileFrom-workcmpuserbardevel I perform the unison synchronization: $ echo $UNISONLOCALHOSTNAME worklaptop $ unison Contacting server... Connected [//worklaptop//home/userfoo/.unisonroot -> //workcmpuserbardevel//home/userbar/.unisonroot] Looking for changes Warning: No archive files were found for these roots, whose canonical names are: /home/userfoo/.unisonroot //workcmpuserbardevel//home/userbar/.unisonroot This can happen either because this is the first time you have synchronized these roots, or because you have upgraded Unison to a new version with a different archive format. Update detection may take a while on this run if the replicas are large. Unison will assume that the 'last synchronized state' of both replicas was completely empty. This means that any files that are different will be reported as conflicts, and any files that exist only on one replica will be judged as new and propagated to the other replica. If the two replicas are identical, then no changes will be reported. If you see this message repeatedly, it may be because one of your machines is getting its address from DHCP, which is causing its host name to change between synchronizations. See the documentation for the UNISONLOCALHOSTNAME environment variable for advice on how to correct this. Donations to the Unison project are gratefully accepted: http://www.cis.upenn.edu/~bcpierce/unison Press return to continue.[<spc>] Waiting for changes from server Reconciling changes local workcmps... dir ----> aDirectoryFrom-worklaptop [f] file ----> aFileFrom-worklaptop [f] Proceed with propagating updates?

The desired result would have been that the two folders would have ended up being identical, holding the union of the contents of the two roots.

Cannot log into Oracle Enterprise Manager 11g: ORA-28001

- by Álvaro G. Vicario

I can no longer log into Oracle Enterprise Manager 11g. I get this error message: ORA-28001: the password has expired (DBD ERROR: OCISessionBegin) I could log into the server using SQL*Plus. I warned me that the password was going to expire in 7 days (which is not the same as being already expired). Following advice from several documents, I ran these commands from SQL*Plus: ALTER USER sys IDENTIFIED BY new_password; ALTER USER system IDENTIFIED BY new_password; SQL*Plus no longer warns about passwords, but I still cannot use the Enterprise Manager. Then I followed this to remove password expiration: ALTER PROFILE default LIMIT password_life_time UNLIMITED And I've also restarted the Oracle services. In case it was using cached credentials, I've tried to connect from several browsers in several computers. No way: I still get ORA-28001 in Enterprise Manager. What am I missing?

OpenVPN on Tomato and Vista - can't see my network

- by Ian

I followed the instructions here (http://todayguesswhat.blogspot.ca/2011/03/quick-simple-vpn-setup-guide-using.html) to set up a TCP connection to OpenVPN on my Tomato router. Used TCP because the place I usually surf at seems to have the other ports blocked. My Vista laptop is able to connect to the router but I don't appear to be getting an IP address. I'm able to access my router's admin page, but I can't see the network at home. When I browse to Whatsmyip I see my home IP. Here are the results of route print -4 when I'm just connect to the library and when I've fired up the VP connection as well: Library only: =========================================================================== Interface List 22 ...00 ff c4 a0 e7 5c ......

Launchd item no longer firing in Snow Leopard

- by ridogi

A launchd item that was working in 10.5 is no longer working after my upgrade to 10.6. I am running 10.6.2 and I have recreated the launchd item and given it a new name and that one doesn't run either. I have found a link of people with the same problem on google groups but none of the advice in that link helps. My launchd item is not listed in /private/var/db/launchd.db/com.apple.launchd/overrides.plist or in any of the overrides.plist files in the subdirectories of /private/var/db/launchd.db/ I have also tried to set this up as both a user agent and a user daemon. My launchd item simply runs a shell script, which I have no problem launching manually. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.eric.tmnotify.launchd</string> <key>ProgramArguments</key> <array> <string>/<path_to>/tmnotify.sh</string> </array> <key>StartInterval</key> <integer>3600</integer> </dict> </plist> I have tried to load it by overriding the disabled key (even though it is not disabled in any of the overrides.plist files) with both: sudo launchctl load -F /Users/eric/Library/LaunchAgents/com.eric.tmnotify.launchd.plist sudo launchctl load -w /Users/eric/Library/LaunchAgents/com.eric.tmnotify.launchd.plist and after running either of them I can see that it is running by using sudo launchctl list but the shell script never fires. Edit: I have also put this in the formerly blank file at /private/var/db/launchd.db/com.apple.launchd.peruser.501/overrides.plist : <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.eric.tmnotify.launchd</key> <dict> <key>Disabled</key> <false/> </dict> </dict> </plist> I also tried inserting this alphabetically: <key>com.eric.tmnotify.launchd</key> <dict> <key>Disabled</key> <false/> </dict> into the file /private/var/db/launchd.db/com.apple.launchd/overrides.plist but still no dice.

How to resolve high CPU + excessive stat("/etc/localtime") and clock_gettime(CLOCK_REALTIME) calls

Things tried so far: Have tried setting time zone as recommended here Made no difference and issue still persists. Content of my /etc/localtime: TZif2UTCTZif2UTC UTC0 Have tried the recommended fix for the leapsecond bug: date -s 'date' No joy so far. I'm fresh out of ideas so any help/advice on how to diagnose or resolve would be greatly appreciated.

Choice and setup of version control

- by Peter M

I am about to set up an new laptop and in the process transition to a new version control system as part of a general cleanup. Currently I use a centralized version control system (yes it is VSS, and yes I know all the pro's and con's of that system, but as a single user system it works well for me). I have very little requirements for a new system and I am free to choose among any of the current mainstream players, but cost constraints will push me towards oss. Some of my requirements are: Runs on a single machine (ie the laptop in question) under windows I am not sharing things with other developers or workers - this is more for my own historical benefits. I want to version source code, documentation and binary files I have a large hierarchy of projects that are unrelated (see below) I have files within the hierarchy that don't need to be controlled (but could be) Some projects use Visual Studio, so some integration there could be nice. There could be some sharing of files between jobs. I generally only need a small about of branching in code files The directory hierarchy that I have at the moment is somewhat like: Root | |--Customer #1 | | | |--Job #1 | | | | | |--Data files received from Customer for Job (not controlled) | | |--Documentation files (controlled) | | |--Project information files (not controlled - but could be) | | |--Software Project Files (controlled) | | |--Scratch dir for job (not controlled) | | | |--Job #2 | | (same structure as above) | |--Customer #2 | |.. | |--Cusmtomer #n |.. Currently I have about 22 customers with differing numbers of projects underneath them. At the moment I have a single VSS repository based at the root of the directory structure. If I kept with a centralized system (ie SVN) I believe that I should keep the same approach and continue with a single repository based from the root dir. Is this a valid approach? However if I move to a distributed tool then I am unsure of how I should handle the situation. My initial guess is that I should not have a repository based on the root of my entire directory structure - but that is a guess so I really don't know how valid it is. Should I pitch a distributed approach at the Root, Customer, Job or sub-Job directory level? Also what I am not clear on with distributed tools (and perhaps with SVN as well), is if I can branch parts of a repository. For example, I can see branching source code in software projects as being useful, but branching my documentation as not being useful. So if I pitch a repository at the Job level, can I just branch the Software Project Files? Or would all files in that Job be branched? Every time I look at distributed tools I get a nagging feeling that they are not suited to my style of setup. I am uncomfortable with idea of having to manually set up something like 50 to 80 separate repositories (if I pitch at the Job level, or 20+ if at the Customer level) within my directory hierarchy. This feeling also extends to having all those repositories scattered around as well - however I do have a backup strategy that I trust, so this latter feeling is pretty well unfounded. So what advice can you all give me? Thanks in advance!

SELF-SOLVED AutoHotkey Function GetMouseTaskbutton need to adapt for 64-bit OS

- by auntyEEK

SOLVED VIA SELF-HELP, HAIR-PULLING, AND TEETH-GRINDING. THANKS ANYWAY....... I'm using the GetMouseTaskbutton function from this thread on AHK forum. [http://www.autohotkey.com/forum/topic22763.html&highlight=getmousetaskbutton][1] ; Gets the index+1 of the taskbar button which the mouse is hovering over. ; Returns an empty string if the mouse is not over the taskbar's task toolbar. ; ; Some code and inspiration from Sean's TaskButton.ahk GetMouseTaskButton(ByRef hwnd) { MouseGetPos, x, y, win, ctl, 2 ; Check if hovering over taskbar.

DllCall("ScreenToClient", "uint", ctl, "uint", &pt) ; Write POINT into explorer.exe. DllCall("WriteProcessMemory", "uint", hProc, "uint", pRB+0, "uint", &pt, "uint", 8, "uint", 0) ; SendMessage, 0x447,,,, ahk_id %ctl% ; TB_GETHOTITEM SendMessage, 0x445, 0, pRB,, ahk_id %ctl% ; TB_HITTEST btn_index := ErrorLevel ; Convert btn_index to a signed int, since result may be -1 if no 'hot' item. if btn_index 0x7FFFFFFF btn_index := -(~btn_index) - 1 if (btn_index > -1) { ; Get button info.

(abs(btn_index) is the index) return btn_index > -1 ? btn_index+1 : 0 } It identifies the owner of the hovered taskbar button. I'm using it in a routine to auto-activate window by hovering its taskbar button, and also a routine to close inactive window by middle-click on its taskbar button. Works great on my XP machine. The author had stated that the function does work in Vista, but it refuses to work for me in Vista 64-bit, so apparently it is only valid in 32-bit. And I am very new to AHK, and don't know how to adapt it. Unfortunately, my queries at the site sank without a trace. Does anyone have advice for me? I will be most grateful. Thanks.

Wordpress Permissions OS X & MAMP

- by Matt2020

I have installed several local versions of Wordpress for development purposes. After the install I can create posts, pages and edit admin options. However as soon as try to upload images which would be saved in wp_content/uploads I get an error: Upload Error: Unable to create directory ...../blog/wp-content/uploads/2011/05. Is its parent directory writable by the server? Looks like MAMP server runs as user _www The blog directory is owned by User1 and the group User1 _www is not in the User1 group, should it be? I do not want to chmod 777 or 765 on the directories just to get it going. Googled up a couple of references: http://codex.wordpress.org/Changing_File_Permissions in "Permission Scheme for WordPress" All files should be owned by your user (ftp) account on your web server, and should be writable by that account. On shared hosts, files should never be owned by the webserver process itself (sometimes this is www, or apache, or nobody user). Any file that needs write access from WordPress should be owned or group-owned by the user account used by the WordPress (which may be different than the server account). For example, you may have a user account that lets you FTP files back and forth to your server, but your server itself may run using a separate user, in a separate usergroup, such as dhapache or nobody. If WordPress is running as the FTP account, that account needs to have write access, i.e., be the owner of the files, or belong to a group that has write access. In the latter case, that would mean permissions are set more permissively than default (for example, 775 rather than 755 for folders, and 664 instead of 644). User and group are User1 (which is admin). Running "ps aux | grep httpd" is running as _www So I think this means Wordpress is running as user _www. So the advice seems contradictory: "files should never be owned by the webserver process" i.e. _www but then later it says "Any file that needs write access from WordPress should be owned or group-owned by the user account used by the WordPress" So isn't this _www again? Another search found this url http://dancingengineer.com/computing/2009/07/how-to-install-wordpress-on-mac-os-x-leopard States Which says: My preferred way to do this is to change the group of the wordpress directory and its contents to _www and give write permissions to the group. Keep the owner as your "username". $ cd /Users/"username"/Sites $ sudo chown -R username:_www wordpress_directory $ sudo chmod -R g+w wordpress_directory However, when I tried this, it did not work for automatic upgrades to newer versions of WordPress although it worked for automatically updating the .htaccess file for pretty permalinks. It is not entirely clear to me what should be done. This last suggestion seems to be saying change the group from User1 to _www and give the group write access, but Wordpress upgrades won't work. Is this the right solution? I would have thought there would be a clear way to set this up on OS X 10.6? Be great if there was a plugin that could run a script for each of the main OS's that Wordpress runs on.

Proliant server will not accept new hard disks in RAID 1+0?

- by Leigh

I have a HP ProLiant DL380 G5, I have two logical drives configured with RAID. I have one logical drive RAID 1+0 with two 72 gb 10k sas 1 port spare no 376597-001. I had one hard disk fail and ordered a replacement. The configuration utility showed error and would not rebuild the RAID. I presumed a hard disk fault and ordered a replacement again. In the mean time I put the original failed disk back in the server and this started rebuilding. Currently shows ok status however in the log I can see hardware errors. The new disk has come and I again have the same problem of not accepting the hard disk. I have updated the P400 controller with the latest firmware 7.24 , but still no luck. The only difference I can see is the original drive has firmware 0103 (same as the RAID drive) and the new one has HPD2. Any advice would be appreciated.

DRBD not syncing between my nodes when IP is reset

- by ramdaz

I am trying to setup DRBD by following the article at http://www.howtoforge.com/setting-up-network-raid1-with-drbd-on-ubuntu-11.10-p2 I am using Ubuntu 10.04 DRBD - 8.3.11 In the first run I had everything working perfectly and when shifting the systems to a production environment I decided to restart the Meta Data creation part and start from scratch. The IPs had changed entirely in the production environment. Issuing drdbadm create-md r0 in both the servers runs successfully. But when I do "drbdadm -- --overwrite-data-of-peer primary all" on the primary it fails to start the re sync. My config file is as given below resource r0 { protocol C; syncer { rate 50M; } startup { wfc-timeout 15; degr-wfc-timeout 60; } net { cram-hmac-alg sha1; shared-secret "aklsadkjlhdbskjndsf8738734jkfkjfkjf"; } on primaryds { device /dev/drbd0; disk /dev/md2; address 172.16.7.1:7788; meta-disk internal; } on secondaryds { device /dev/drbd0; disk /dev/md2; address 172.16.7.3:7788; meta-disk internal; } } Status on primary root at primaryds:~# cat /proc/drbd version: 8.3.7 (api:88/proto:86-91) GIT-hash: ea9e28dbff98e331a62bcbcc63a6135808fe2917 build by root at primaryds, 2012-05-12 15:08:01 0: cs:WFBitMapS ro:Primary/Secondary ds:UpToDate/Inconsistent C r---- ns:0 nr:0 dw:0 dr:200 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:5690352828 Status on secondary root at secondaryds:/etc/drbd.d# cat /proc/drbd version: 8.3.7 (api:88/proto:86-91) GIT-hash: ea9e28dbff98e331a62bcbcc63a6135808fe2917 build by root at secondaryds, 2012-05-12 15:25:25 0: cs:WFBitMapT ro:Secondary/Primary ds:Inconsistent/UpToDate C r---- ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:5690352828 Log of Primary May 30 13:42:23 primaryds kernel: [ 1584.057076] block drbd0: role( Secondary -> Primary ) disk( Inconsistent -> UpToDate ) May 30 13:42:23 primaryds kernel: [ 1584.086264] block drbd0: Forced to consider local data as UpToDate!

How do I reset/update my BIOS for Optiplex GX280?

- by Sam Langlhey

So far this has been a nightmare for me, which has been frustrating me constantly. I am using Dell Optiplex GX280 with Windows XP home edition, which is running a BIOS version A04. Recently, i've rebooted the pc to find out that its not booting. It will get to the Windows boot up screen with the progress bar but only to restart to the same process again, over and over. Frustrated that I am, i've inserted the Windows recovery CD to at least either repair of reinstall the operating system to find out that was not possible. I hit F8 to have the boot options, each of the boot option that I've selected gave me an error saying: "Selected boot device is not available." Right after that, I went to the BIOS setting and did a diagnostic test, which recognized all the Boot devices onboard. Now, I cannot even repair of reinstall Windows XP, because the system is not booting from none of the boot devices. The surprise is when I removed the hard-drive from the computer and loaded it on into another computer successfully; that's right, there is nothing wrong with the hard drive. After that I was totally puzzled. I found a few pointers online saying that the BIOS start-up block might be corrupted itself and I might need to flash/update the BIOS. I found the detailed instruction on how to create a Boot up disk by downloading the BIOS firmware from the manufacture's website. I did exactly as instructed below: Download the latest version or your choose version of BIOS file for your computer or motherboard from the manufacturer’s support site. Rename the downloaded file to AMIBOOT.ROM. Copy the file to a floppy disk. Insert the floppy disk to the floppy drive. Turn on the system. After I did that and powered on the PC to boot from the floppy drive, it gave me this error message: "Non-System Disk or Disk Error. Replace and Strike any key when ready." I did all that, and I kept on pressing [Ctrl]+[Home] to force it, but it did not did any satisfying result. Desperate as I am, my next attempt is to try the instruction below. Since I want to be ready, in the event it does not work, do you have any solution that you can provide? Please keep in mind that I cannot boot from any of the devices at this moment. My only hope now is to come on with a solution that will work through the Floppy drive, since that's the only drive that affected. Thank you very much for your advice and support in advance. To create a Windows startup disk, insert a floppy disk into the drive of a similarly configured, working Windows XP system, launch My Computer, right-click the floppy disk icon, and select the Format command from the context menu. When you see the Format dialog box, leave all the default settings as they are and click the Start button. Once the format operation is complete, close the Format dialog box to return to My Computer, double-click the drive C icon to access the root directory, and copy the following three files to the floppy disk: Boot.ini NTLDR Ntdetect.com

Linux: Apple Wireless A1314 Fn key not registered, looks like software bug

- by ramplank

I'm trying to set up my Apple Wireless Keyboard with my Kubuntu systems. These are PC hardware powered by Intel Atom and Intel i5 respectively. The keyboard has a US keyboard layout and has model number A1314 written on the back. It takes two AA batteries. I'm saying that because it appears there are multiple types of model A1314. I have tried this on a 10.04, 11.04, 11.10 and 12.04 system with no success. Every time using a bluetooth dongle and the KDE bluetooth notification tray applet, the keyboard can be connected. In both cases it shows up as "Apple Wireless Keyboard". Almost everything works as expected, in fact, I'm typing on it right now. But one thing doesn't: The Fn key. I'd like to use Fn + Down Arrow as PgDn / Page Down, I understand this is default behaviour on Apple keyboards. And of course I'd like the same for Page Up, Home and End. I'll stick to Page Down in my example. I used the xev tool to see the keycodes the system receives, and if I press on Fn nothing happens, and nothing is registered. If I press Fn + Down Arrow, xev only registers the down arrow. Here's the output from my 11.04 system to illustrate: Press just the Fn key: no output Press Down Arrow key: KeyPress event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2699773, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2699860, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False Press Fn+Down Arrow Keys together: KeyPress event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2701548, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x4400001, root 0x15d, subw 0x4400002, time 2701623, (44,45), root:(1352,298), state 0x10, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False I've been searching this forum and other Linux-related forums for hours but I still have not found a solution. I mostly found advice on how to fix this when using an actual apple laptop or desktop, but I don't have that. They said to try something like the following echo 2 > /sys/module/hid_apple/ ... But since there's no hid_apple directory present on my systems, I've needed to modprobe hid_apple first. That didn't help either. I'm cool with changing some config files, or compiling my own patched kernel if that's necessary. I currently have a 10.04 and 12.04 system available to test. The same issue occurs when hooked up to Windows 7. Fn key still does nothing, not by itself or in combination with other keys. With some AutoHotkey fiddling, I was able to confirm the key is registered as pressed, but ignored by default. A custom AutoHotkey script can fix that. But AutoHotkey is only for Windows, I want my problem fixed on Linux. Hooked up to an iPad 2 it only works in combination with the F1-F12 keys. Not with the arrow keys. If the screen of the ipad is off, and I press just the Fn key, the screen will come on, so the key itself is registered as pressed. So to sum up my question: Can anyone help me get Page Up, Page Down, Home and End to work on this keyboard, when that requires me to use an Fn key which is currently not registered?

Connect to VPN from Mac on Time Capsule network

- by Lou Franco

I have a few clients on my network that can connect to my work VPN (Windows PPTP) when they are not on my home network. On my home network (Cable Modem with Time Capsule providing Wifi), it fails very early -- looks like it can't even establish a connection. Logs just say that it failed -- even verbose logs don't have much: I redacted the host and IP from this log, but I can ping it. Wed Feb 2 14:32:41 2011 : PPTP connecting to server 'XXX.XXX.com' (XXX.XX.XX.XX)... Wed Feb 2 14:32:41 2011 : PPTP connection established.

The only clue I have seen in other forums is to set the NAT default host on the Time Capsule -- I set this to the IP that my mac got over DHCP. I made sure that my Mac gets a different range of IP addresses that it would get if it connected to the VPN (192.168.1.x vs. 10.0.0.x). Not using any VPN client -- just Network System Preferences. It has worked in the past -- but it was a while ago, so I can't pinpoint a change. My sysadmin doesn't even see incoming connections to the VPN (nothing logged about me when I connect). Looking for any diagnostic advice at all

"The server closed the connection without sending any data"

- by Toby

Server setup The problem Diagnostic information What I've tried Specific Help needed 1. I have the following server setup: Debian Squeeze Linux 2.6.32-5-amd64 Apache2-mpm-prefork 2.2.16-6+squeeze10 PHP 5.3.3-7+squeeze14 This server is protected with the Suhosin Patch 0.9.9.1 Max Requests Per Child: 0 - Keep Alive: on - Max Per Connection: 100 Timeouts Connection: 300 - Keep-Alive: 15 Loaded Modules core mod_log_config mod_logio prefork http_core mod_so mod_alias mod_auth_basic mod_auth_digest mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_cgi mod_deflate mod_dir mod_env mod_mime mod_negotiation mod_php5 mod_reqtimeout mod_rewrite mod_setenvif mod_ssl mod_status Wordpress 3.4.2 (Upgrading to 3.5 soon :) 2. The problem When I restart the server (sudo shutdown -r now), going to any website page results in the following error from the web browser (in this case, Google Chrome, but other browsers also show the same error). This error can also occur an hour or so after all is working ok, seemingly randomly, which is my biggest concern as it means my server is not reliable: No data received Unable to load the web page because the server sent no data. Here are some suggestions: Reload this web page later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. 3. Diagnostic information The apache error log contains the folowing entries: [Fri Dec 14 22:23:27 2012] [notice] child pid 1955 exit signal Floating point exception (8) [Fri Dec 14 22:23:27 2012] [notice] child pid 1956 exit signal Floating point exception (8) [Fri Dec 14 22:23:29 2012] [notice] child pid 1957 exit signal Floating point exception (8) [Fri Dec 14 22:23:30 2012] [notice] child pid 1958 exit signal Floating point exception (8) [Fri Dec 14 22:23:32 2012] [notice] child pid 1959 exit signal Floating point exception (8) [Fri Dec 14 22:23:32 2012] [notice] child pid 1960 exit signal Floating point exception (8) [Fri Dec 14 22:23:34 2012] [notice] child pid 1961 exit signal Floating point exception (8) [Fri Dec 14 22:23:34 2012] [notice] child pid 1962 exit signal Floating point exception (8) 4. What I've tried a) I can 'fix' the website temporarily by resetting the server twice (resetting it once does not work) using the following commands. NB: the 'reload' option does not work, I have to use restart twice. However, the error can reoccur sometime later. sudo /etc/init.d/apache2 restart sudo /etc/init.d/apache2 restart b) I have tried disabling suhosin by uninstalling php5-suhosin, but a php info page still shows "This server is protected with the Suhosin Patch 0.9.9.1". I have tried putting Suhosin into simulation mode by creating a file /etc/php5/apache2/conf.d/suhosin.ini containing: [suhosin] suhosin.simulation = On The php info page shows the suhosin.ini file in the list of "Additional .ini files parsed" but the php info page still shows "This server is protected with the Suhosin Patch 0.9.9.1" c) Increasing the PHP memory limit In /etc/php5/apache2/ : ; Maximum amount of memory a script may consume (128MB) ; http://php.net/memory-limit memory_limit = 512M d) Disabling all Wordpress plugins, and going back to the default theme. 5. Specific help needed I would very much like help in debugging what is going on here. I am not sure how to determine what processes are in the Apache error log which are exiting "[notice] child pid 1955 exit signal Floating point exception (8)", or what is causing them to exit. And whether suhosin is part of the problem (and how to disable it if it is). Thank you in advance for any advice or tips you can offer in helping me debug this.

Installing EclipseFP on Mac OS X

- by Dom Kennedy

I am trying to install EclipseFP. I'm running OS X Mavericks. I've tried following both the official installation instructions and the advice in this answer on SU, but I'm still having the same problem. I can get the plugin itself installed painlessly using Help -> Install New Software..., Bbut when I restart and switch to the Haskell perspective, things start to go wrong. The installation instructions tells me that I should receive a prompt to install BuildWrapper and Scion Browser. I do not receive this prompt. Furthermore, if I create a new Haskell project, my code has no syntax highlighting, and the Hoogle search feature does not appear to do anything. It's clear that the plugin is not set up correctly yet. I've tried running cabal update in Terminal, but this does not change anything. After several attempts going round in circles with this on Eclipse Juno, I uninstalled Eclispe and the Haskell Platform and performed a clean install of Eclipse Luna and the latest Haskell Platform. However, the problems are persisting. I've tried going into Preferences to see if I could sort any of this out manually. I should initially point out that my GHC installation seems to be correctly references under Preferences -> Haskell Implementations Under Haskell -> Helper executables, there are areas for configuring the options of both BuildWrapper and Scion Browser. At present, both are blank. I tried clicking the Install from Hackage... button beside each of them with no success; I receive an error message saying Expected executable <workspace>/.metadata/.plugins/net.sf.eclipsefp.haskell.ui/sandbox/.cabal-sandbox/bin/buildwrapper not found!` (replace buildwrapper for scion-browser and the message is the same) The Eclipse console displays the following exception after doing the above with BuildWrapper: src/Language/Haskell/BuildWrapper/GHCStorage.hs:313:32: Not in scope: data constructor ‘MatchGroup’ cabal.real: Error: some packages failed to install: buildwrapper-0.7.4 failed during the building phase. The exception was: ExitFailure 1 and after doing it for Scion-Browser: zip-archive-0.2.3.4 (reinstall) changes: text-1.1.0.0 -> 0.11.3.1 pandoc-1.12.3.3 (latest: 1.13) -http-conduit (new version) Graphalyze-0.14.1.0 (reinstall) changes: pandoc-1.12.4.2 -> 1.12.3.3, text-1.1.0.0 -> 0.11.3.1 cabal.real: The following packages are likely to be broken by the reinstalls: pandoc-1.12.4.2 unordered-containers-0.2.4.0 aeson-0.7.0.4 scientific-0.2.0.2 case-insensitive-1.1.0.3 HTTP-4000.2.10 Use --force-reinstalls if you want to install anyway. After receiving similar results as the above on previous attempts, I've tried using force-reinstalls and ended up at more dead ends. I am at a loss as to what is wrong and how to solve this. I should point out that my GHC installation appears to be correctly configured under Preferences -> Haskell -> Haskell Implementations. Apologies if any of this information is irrelevant, I'm just not really sure what is important and what isn't at this point. Any help anyone could provide me with would be greatly appreciated.

How do I allow mysqld to use more than 24.9% of my cpu?

- by Joseph Yancey

I have a Web server running on RHEL that is running Apache and MySQL. It has a Quad core 3.2Ghz Xeon CPU and 8 Gigs of RAM Most of the time, we don't have any issues at all. Our web application is very database intensive. When our usage gets pretty heavy MySQL will peg out at using 24.9% of the cpu. Most of the time, it hangs around below 5%. I have speculated that it is only using one core of the CPU and it is pegging out that core but TOP shows me in the cpu column that mysqld changes cores even while the usage stays at 24.9%. When it does this MySQL gets painfully slow as it is queuing up queries Is there some magic configuration that will tell mysql to use more cpu when it needs to? Also, any other advice on my configuration would be helpful. We run two applications on this server. One that runs Innodb but doesn't get much usage (it has been replaced by the other app), and one that runs MyIsam and gets lots of use. Overall, our whole mysql data directory is something like 13Gigs if that matters at all. Here is my config: [root@ProductionLinux root]# cat /etc/my.cnf [mysqld] server-id = 71 log-bin = /var/log/mysql/mysql-bin.log binlog-do-db = oldapplication binlog-do-db = newapplication binlog-do-db

Exchange Server 2007 Send and Receive Connectors

- by Mistiry

I have gotten awesome advice from users on here for getting Exchange on Windows SBS 2008 set up. I think this is the final piece and I'm ready for roll-out! I need to set up Exchange so that it RECEIVES mail from our existing mail server as a Forward [aliases on the existing mail server to forward mail from [email protected] to [email protected]] (not using the POP3 Connector), and SENDS mail through that server as well (sends from [email protected] to [email protected] and then out to the world, showing in the headers as from [email protected] or at absolute least have the reply-to set as this). Alternatively, as long as the .net email address doesn't show in the From and replies are directed to the .com account, email can go from Exchange to the outside world without directing through the existing mail server. External Domain: domain.com Internal Domain: domain.local Internet Domain Name Set in SBS Console: domain.net When I go to http://remote.domain.net I get the Remote Web Workspace, and can login to both Sharepoint and OWA. I can send an email from OWA to a GMail account. I receive it from [email protected], which is an alias of [email protected]. I cannot, however, send an email from OWA to ANY domain.com email addresses. I am also not receiving any email to this Exchange account (except for NDRs). When I try sending an email to a domain.com account, here is the error (I had to replace all < and with { and }): Delivery has failed to these recipients or distribution lists: [email protected] The recipient's e-mail address was not found in the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator. Generating server: IFEXCHANGE.domain.local [email protected] #550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ## Original message headers: Received: from IFEXCHANGE.domain.local ([fe80::4d34:abc5:f7fd:e51a]) by IFEXCHANGE.domain.local ([fe80::4d34:abc5:f7fd:e51a%10]) with mapi; Tue, 17 Aug 2010 14:14:14 -0400 Content-Type: application/ms-tnef; name="winmail.dat" Content-Transfer-Encoding: binary From: John Doe {[email protected]} To: "[email protected]" {[email protected]} Date: Tue, 17 Aug 2010 14:14:12 -0400 Subject: asdf Thread-Topic: asdf Thread-Index: AQHLPjf+h6hA5MJ1JUu1WS4I4CiWeA== Message-ID: {E4E10393768D784D8760A51938BA456A029934BA30@IFEXCHANGE.domain.local} Accept-Language: en-US Content-Language: en-US X-MS-Has-Attach: X-MS-TNEF-Correlator: {E4E10393768D784D8760A51938BA456A029934BA30@IFEXCHANGE.domain.local} MIME-Version: 1.0 I hope I explained the situation well enough for someone to be able to explain to me what I'm missing. If I could, I'd be putting a 10K bounty, but unfortunately I've got only 74 reputation (hey, I'm a newbie here!). I'm pretty sure the obvious "RecipNotFound" error is why its not working, my question is how to resolve this. The email account exists, it receives mail just fine, yet when I send it from the Exchange server it fails. EDIT In OC-Hub Transport, the Email Address Policies has 2 entries. "Windows SBS Email Address Policy" is set up to: Include All Recipient Types, no conditions, and SMTP %[email protected]. "Default Policy" set to: Include All Recipient Types, no conditions, and SMTP @domain.net. Three Authoritative Accepted domains domain.com domain.local (Default) domain.net Remote Domains tab has two entries. Default with domain * Windows SBS Company Web Domain with domain companyweb.

Network config / gear question

- by mcgee1234

I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

Getting sendmail to install/work for using php mail()

- by harryg

I'm running WordPress on a Ubuntu VPS. When WordPress tries to send an email like a password reset or registration email it never gets delivered. WordPress uses php's mail() function. I figure it's not working as my VPS didn't have sendmail installed. So I went into SSH and installed it with sudo apt-get install sendmail which appeared to succeed. Following more googled advice I edited the php.ini file to have the sendmail path. I located it as being /usr/sbin/sendmail which I believe is typical for many *nix servers. To check I browsed to this directory on FTP. The "sendmail" directory appears to be a shortcut. Is this correct/expected? Either way the php mail function is not working. I have created a phpinfo file and a test mail php file which contains just a mail() function with my email as the recipient. Note: my VPS doesn't yet have a domain, just an IP address. Would this affect sendmail functionality? My phpinfo is here for your reference: http://95.142.166.209/phpinfo.php Do I also need postfix? I don't think I have it... Here is some of the mail log. I executed the mail function towards the end: Nov 27 18:41:02 sergeserver sm-msp-queue[5450]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:00:01 sergeserver sm-msp-queue[5497]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:01:01 sergeserver sm-msp-queue[5497]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:20:01 sergeserver sm-msp-queue[5532]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:21:01 sergeserver sm-msp-queue[5532]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:40:01 sergeserver sm-msp-queue[5568]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:41:01 sergeserver sm-msp-queue[5568]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:00:01 sergeserver sm-msp-queue[5605]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:01:01 sergeserver sm-msp-queue[5605]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:20:01 sergeserver sm-msp-queue[5641]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:21:01 sergeserver sm-msp-queue[5641]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:40:01 sergeserver sm-msp-queue[5675]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:41:01 sergeserver sm-msp-queue[5675]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:00:01 sergeserver sm-msp-queue[5712]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:01:01 sergeserver sm-msp-queue[5712]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:20:02 sergeserver sm-msp-queue[5747]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:21:02 sergeserver sm-msp-queue[5747]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:40:01 sergeserver sm-msp-queue[5782]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:41:01 sergeserver sm-msp-queue[5782]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:00:01 sergeserver sm-msp-queue[5831]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:01:01 sergeserver sm-msp-queue[5831]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:20:01 sergeserver sm-msp-queue[5866]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:21:01 sergeserver sm-msp-queue[5866]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:37:19 sergeserver sendmail[5903]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:38:19 sergeserver sendmail[5903]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:38:19 sergeserver sendmail[5903]: qARLcJYI005903: from=adminftp, size=158, class=0, nrcpts=0, msgid=<201211272138.qARLcJYI005903@sergeserver>, relay=adminftp@localhost
