• Maxtor 500GB external hard drive not being detected but power is going to it?

  - by ClarkeyBoy

  I have 2 * Maxtor Onetouch 4 Lite 500GB external hard drives (part no. 9NT2A4-500). They both used to work fine on my old laptop (an Acer) but I have not used them for about a year, since my laptop was stolen and I got this one (also an Acer [Aspire 7738G]). I have one plugged into the mains with one of the leads I believe was supplied with them. It appears to be receiving power as it is warm and the power light (on the unit itself) is on; also the mains adapter is fairly warm. I also have it plugged into my laptop with a USB lead which I have tested on my mp3 player (so I know it works). However my hard drive is not showing on my computer. I have tried checking for new hardware, installing the software that was supplied with it, checking drive letters in case it is registered as C: or something stupid, checking for problems etc... I can't find any cause for it to do this. It does appear to be starting up and, possibly, shutting down and restarting constantly (that's what it sounds like altho I can't be certain). I have had both hard drives stored in different places for the last year and they're both doing the same thing.. if it was only one then I'd guess it had got damaged or corrupted or something but since it is both I doubt this is it. The only things in common with both of them are the leads and the laptop, however I know the USB lead works and guess the mains lead works as there is power going to the unit. Has anyone come across this before or does anyone have any idea what the cause / solution to the problem is? Any help would be greatly appreciated. Regards, Richard

• Copying email with qmail and Plesk

  - by Greg

  I need to keep a copy of all outgoing and incoming email (for a single domain if possible) using qmail or Plesk. I can't recompile qmail, so qmailtap is out of the question, as is setting QUEUE_EXTRA in extra.h. I'm pretty sure it should be possible with Plesk's mailmng utility, aka Mail Handlers but I'm having trouble getting them to work. I've registered 2 hooks: incoming hook ./mailmng --add-handler --handler-name=incoming --recipient-domain=example.com --executable=/xxx/incoming.sh --context=/xxx/incoming/ --hook=before-local incoming.sh #!/bin/bash # The email is passed on stdin - grab it to a variable e=`cat -` # $1 = context (/xxx/incoming) # $3 = recipient ([email protected]) # Create /xxx/incoming/[email protected] mkdir -p $1$3 # Save the email to /xxx/incoming/[email protected]/0123456789.txt echo "$e" > $1$3/`date +%s%N`.txt # Echo PASS to stderr echo 'PASS' >&2 # Echo the email to stdout echo "$e" outgoing hook # ./mailmng --add-handler --handler-name=outgoing --sender-domain=holidaysplease.com --executable=/xxx/outgoing.sh --context=/xxx/outgoing/ --hook=before-remote The outgoing.sh file is the same as incoming.sh, except replace $3 (recipient) with $2 (sender). The incoming hook does work, but saves 2 copies of each email - one before and one after SpamAssassin has run. The outgoing hook doesn't seem to get called at all. So finally, my questions are: How can I make the incoming hook save only a single copy (preferably after SpamAssassin has run)? How can I get the outgoing hook to work?

• Swapping Function (Fn) and Control (Ctrl) Keys on Lenovo ThinkPad W500

  - by Howiecamp

  I'd like to swap the Fn and Ctrl keys on my ThinkPad W500 (like many others!). I wanted to comment on http://superuser.com/questions/35228/how-can-i-switch-the-function-and-control-keys-on-my-laptop and StackOverflow question 514781 (please Google it because I don't have enough rep to include 2 hyperlinks) but I don't have enough rep to do so to comment. Numerous folks (in both the above questions and on other Google searches) indicate that Windows doesn't register the Fn key as a keypress but using a tool that gives the ASCII value of a keypress (visit www mihov com / eng / am.html) I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy. Short of retraining my pinky I'm actually considering removing the keyboard and resoldering the connections to swap those keys. I'd love to get some input as to the root technical issue(s) and possible solutions here. Thanks

• Microsoft Windows DHCP: Steering IPv4 clients into specific scopes based on MAC

  - by Easter Sunshine

  We have visitors on our campus who bring their own laptops and devices and use our wireless and wired networks. When we receive a copyright infringement notice (typically BitTorrenting), we are required to quarantine that MAC address so that it no longer has Internet access. No matter what website it tries to visit, it is sent to a web page explaining to the user that the device has been quarantined. We have thus far implemented this in ISC DHCP on Linux. We have multiple VLANs with one or more public-IP subnets and one RFC1918 quarantine subnet each. All clients are leased IPs in the public-IP subnet(s) unless you're in a list of known bad MACs. Then, you are sent to the quarantine subnet so that your traffic is unroutable on the Internet (you are isolated by subnet only, not by VLAN). We would like to move to Windows DHCP in light of the IPAM role but I cannot figure out how to replicate this in Windows DHCP 2012 (Assign DHCP IPs for specific MAC prefixes on Windows Server 2008 R2 suggests it was not possible in 2008 R2), even while using policies. So here's what I'd like: The administrator/help desk provides and maintains a list of MAC addresses that are to be quarantined. The DHCP server places those MACs into the quarantine subnet on the respective VLAN, no matter which VLAN the client is in. I don't think reservations would work: We currently have about 300 registered bad MACs and about 12 VLANs. I don't want to make 300 x 12 reservations nor have to add 12 reservations per new MAC address. Not to mention all of the quarantine subnets are /24s. We do not have NPS/NAC. You do not have to register your MAC address get network access. We use Cisco routers/switches. Thanks.

• One Comcast Business Gateway, One Router, Two Web Servers

  - by Kevin Scheidt

  I have a Comcast business account with a router and a web server (info) attached. behind the router there are multiple computers and a second web server (info) which also serves as a file server. (info) has two nics in it. One direct to comcast and one connected to the router. It needs to serve the world it's websites. It needs however, to also be able to see all the internal computers and (com)'s served files. With just 1 nic (the one connected to the router, not comcast), (info) works fine but no one outside can see it. (com) services port 80 and (info) needs to handle port 80 as well. I have two domain names registered, and 5 static ip's from comcast. right now h t t p: / /www.graceamazing.com handled by (com) works fine and h t t p: / /www.graceamazing.com:1307 handled by (info) works fine. but as soon as I enable the 2nd nic in (info) h t t p: / /www.graceamazing.info runs extremely slow (Horribly slow). however, h t t p: / /www.graceamazing.com:1307 and .com work fine. (com) has an ip address via the router 70.89.233.41 (info) has a ip addy of 70.89.233.46 via comcast (2nd nic) and a internal ip of 192.168.x.100 via static behind the router. Any suggestions or changes to make that will make h t t p: / /www.graceamazing.info perform with the same speed it has when going through h t t p: / /graceamazing.com:1307 is there a setting I should check / could have misssed?

• Password-protected sharing allows access to users who have no account?

  - by romkyns

  Running Win7 on two computers in my LAN. Computer A has password-protected sharing enabled, and shares a folder. It has a single user account "Bob", and the Guest account is turned off. The network is workgroup-based. According to the descriptions of the "password-protected sharing" I could find, the only people who can access the shared folder via the LAN are those who know the username+password for the "Bob" account. However a second computer on the LAN is able to view this shared folder by simply browsing to Computer A. They don't need to enter any passwords or anything. The only user account registered on that PC is called "Jim", and has a different password from "Bob". How on earth is computer B able to view this shared folder? Is the popular description of the "password-protected sharing" feature inaccurate / did I misunderstand it big time? P.S. There is a possibility that the password for "Bob" has been entered on that PC once, and possibly the "remember password" box was checked. I've looked in the "Credential Manager" on both computers and there is nothing saved anywhere.

• A star vs internet routing pathfinding

  - by alan2here

  In many respects pathfinding algorythms like A star for finding the shortest route though graphs are similar to the pathfinding on the internet when routing trafic. However the pathfinding routers perform seem to have remarkable properties. As I understand it: It's very perfromant. New nodes can be added at any time that use a free address from a finite (not tree like) address space. It's real routing, like A*, theres never any doubling back for example. IP addresses don't have to be geographicly nearby. The network reacts quickly to changes to the networks shape, for example if a line is down. Routers share information and it takes time for new IP's to be registered everywhere, but presumably every router dosn't have to store a list of all the addresses each of it's directions leads most directly to. I can't find this information elsewhere however I don't know where to look or what search tearms to use. I'm looking for a basic, general, high level description to the algorithms workings, from the point of view of an individual router.

• Adding new SPNs to existing service ids

  - by jmh

  We have a tomcat server using spring-security kerberos to authenticate users to the webpage against active directory. There are around 25 domain controllers. The site has two CNAME based DNS aliases. The site currently has one Service ID with SPNs registered for the DNS A record as well as each of the CNAMEs. While everything is working right now, I don't know how to reliably change this configuration without possible downtime. The reason is that clients cache kerberos tickets: http://www.juniper.net/techpubs/en_US/uac4.2/topics/concept/user-role-active-directory-about.html The 'kerbtray.exe' program is helpful for viewing and deleting Kerberos tickets on the endpoint. Old tickets must be purged from the endpoint if SPNs are updated or passwords are changed (assuming the endpoint still has a cached copy of the ticket from a prior SPNEGO request to the MAG Series device. During testing, you should purge tickets before each authentication request. Description of "klist" program used to inspect/delete cached tickets: http://technet.microsoft.com/en-us/library/hh134826.aspx So if each of the clients (users running windows) who connect to my web server have kerberos tickets that become invalid as soon as I update the SPNs or passwords, how do I ensure changes are seamless? Are there any operations that can be done safely? I can't just ask all of the users to install klist and delete their old tickets.

• How do I compile DarWINE in PowerPC Mac OS X 10.4.11...?

  - by Craig W. Davis

  So far I've tried using MacPorts which gives me this error: /Error: Cannot install wine for the arch(s) 'powerpc' because Error: its dependency pkgconfig is only installed for the archs 'i386 ppc'. Error: Unable to execute port: architecture mismatch To report a bug, etc...

I've also tried the build script that I found at http://code.google.com/p/osxwinebuilder/#Building_Wine_via_the_script... None of these attempts to build DarWINE have actually worked.

I run ./winemaker ~/Downloads/WINE/wine-1.2.2 or ./winemaker ~/Downloads/WINE/wine-1.2-rc2 (the reason for trying WINE 1.2-rc2 is that some people managed to get it to build on PowerPC Macs running 10.5.8...)./ I made sure to install Xcode Tools 2.5 & all the SDKs too...

• (Zywall USG 300) NAT bypassed when accessing in-house-server From LAN Via domain name

  - by mschr

  My situations is like this; i host a number of websites from within our joint network solution. On the network is basically 3 categories: the known public, registered via mac, given static dhcp lease the anonymous lan connections, given lease from specific dhcp range switches, unix hosts firewall Now, consider following hosts which are of interest 111.111.111.111 (Zywall USG 300 WAN) 192.168.1.1 (ZyWall USG 300 LAN) load balances and bw monitors plus handles NAT 192.168.1.2 (Linux www) serves mydomain1.tld and mydomain2.tld 192.168.123.123 (Random LAN client) accesses mydomain1.tld from LAN 23.234.12.253 (Random External client) accesses mydomain1.tld via WAN DNS A records are setup so that both mydomain1.tld and mydomain2.tld points to 111.111.111.111 - and the Linux www serves the http parts with VirtualHost configurations, setting up the document roots pr ServerName, this is not so interesting though.. NAT rule translates 111.111.111.111:80 to 192.168.1.2:80 (1:1 NAT) Our problem follows; When accessing http://mydomain1.tld from outside (23.234.12.253 example host) the joint network - everything is fine, zywall receives requests via port 80 and maps it to the linux host' httpd. However - once trying to go through the NAT from LAN side (in-house, 192.168.123.123 example host) then one gets filtered in the Zywall port 80 firewall. I know this only because port 443 is open for administration interface and https://mydomain1.tld prompts for zywall login. So my conclusion is, that the LAN that accesses 111.111.111.111 in fact are routed to 192.168.1.1 whilst bypassing the NAT table. I need to know how to setup NAT / Policy Route, so that LAN WAN LAN will function with proper network translations instead of doing the 'quick nameserver lookup' or whatever this might be.

• What is /etc/apache2/sites-available used for and is it necessary?

  - by Mariane

  I have 3 sites, each with a specific IP, running on apache2 (up-to-date Ubuntu). To put a site online, I just created a file in: /etc/apache2/sites-enabled and in this file I told apache which directory was the root directory for this site, and to which IP it should correspond. So I have 000-default 001-www.lapf.eu 002-www.felkin.info 003-www.seidhr.fr in this directory. My first site, lapf suddenly lost contact with its database after the domain name was transferred from another registrar unto the registrar who is also hosting the site's data. Then I did an update, and I reinstalled mysql-server and mysql-common, and I did I-have-forgotten-what to reinstall the locales (uft8 and such) which had vanished for some reason. This fixed my first site. Now I noticed that the other 2 sites are offline. Pointing a browser to them just hangs until timeout. They used to function, and their domain names did not move, they are still registered at the same place. The files are still in /etc/apache2/sites-enabled I noticed another directory: /etc/apache2/sites-available with just defaut and default.ssl in it. Why are there 2 directories, sites-enabled and sites-available? Should I copy the files from "sites-enabled" into "sites-available"? Or should I put a modified version of each in "sites-available"? command: "apache2ctl -S" VirtualHost configuration: 92.243.20.169:80 Charlotte (/etc/apache2/sites-enabled/001-www.lapf.eu:1) 92.243.21.141:80 xvm-21-141.ghst.net (/etc/apache2/sites-enabled/002-www.felkin.info:1) 92.243.4.114:80 xvm-4-114.ghst.net (/etc/apache2/sites-enabled/003-www.seidhr.fr:1) wildcard NameVirtualHosts and default servers: *:80 is a NameVirtualHost default server Charlotte (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost Charlotte (/etc/apache2/sites-enabled/000-default:1) Syntax OK

• Cannot access domain from windows 2003 client

  - by Peuge

  Hey all, First off I am a novice at AD and DNS so please bear with me. This is my current situation: I have one server which is a DC and DNS server (win2k3) - Machine 1. I have another machine which is trying to join this domain - Machine2. This machine is also a win2k3 server. This is what I have done so far: I have setup DNS on the DC and its tcp/ip dns is pointing to itself. On machine2 I have set its dns to point to the dc. The DNS has been setup with a forward lookup zone with the same name as the domain (accdirect.com). I can ping machine1 from the machine2 by its FQDN and ip. I have set up forwarders on the DC for our ISP dns and can browse the internet on both machines. In the DNS mmc on the DC I can see a host (A) has been created for machine2. The problem is I still cannot join the domain. When I try join the domain via my computer - properties then it brings up the username/password box and after I go "ok" it says cannot find domain accdirect.com If I run this from machine2 dcdiag /s:accdirect.com /u:accdirect.com\admin /p: then I get the following: Performing initial setup: ** Warning: could not confirm the identity of this server in the directory versus the names returned by DNS servers. If there are problems accessing this directory server then you may need to check that this server is correctly registered with DNS [accdirect.com] Directory Binding Error 1722: Win32 Error 1722 This may limit some of the tests that can be performed. Done gathering initial info. On the dc all dcdiag and netdiag results pass. If anyone could help me I would really appreciate this! Sorry if any of my terminology is a bit off, I have only been doing this for two days. thanks Peuge

• Creating Active Directory on an EC2 box

  - by Chiggins

  So I have Active Directory set up on a Windows Server 2008 Amazon EC2 server. Its set up correctly I think, I never got any errors with it. Just to test that I got it all set up correctly, I have a Windows 7 Professional virtual machine set up on my network to join to AD. I set the VM to use the Active Directory box as its DNS server. I type in my domain to join it, but I get the following error: DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "ad.win.chigs.me": The query was for the SRV record for _ldap._tcp.dc._msdcs.ad.win.chigs.me The following domain controllers were identified by the query: ip-0af92ac4.ad.win.chigs.me However no domain controllers could be contacted. Common causes of this error include: - Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses. - Domain controllers registered in DNS are not connected to the network or are not running. It seems that I can talk to Active Directory, but when I'm trying to contact the Domain Controller, its giving a private IP to connect to, at least thats what I can make out of it. Here are some nslookup results. > win.chigs.me Server: ec2-184-73-35-150.compute-1.amazonaws.com Address: 184.73.35.150 Non-authoritative answer: Name: ec2-184-73-35-150.compute-1.amazonaws.com Address: 10.249.42.196 Aliases: win.chigs.me > ad.win.chigs.me Server: ec2-184-73-35-150.compute-1.amazonaws.com Address: 184.73.35.150 Name: ad.win.chigs.me Address: 10.249.42.196 win.chigs.me and ad.win.chigs.me are CNAME's pointing to my EC2 box. Any idea what I need to do so that I can join my virtual machine to the EC2 Active Directory set up I have? Thanks!

• Ubuntu Laptop as a wireless hotspot on bridge mode

  - by nixnotwin

  I have a wired router to which my ubuntu laptop connects via ethernet. The wierless NIC of the laptop acts as a wireless hotspot on master mode. I use hostapd fo this. I have bridged eth0 and wlan0, so my wireless clients that connect to my laptop over wifi get ip from the wired router via dhcp, so the devices get registered at the wired router ( and the laptop is just an access point). I use the following commands to get my laptop+accesspoint working: sudo brctl addbr br0 sudo brctl addif br0 eth0 sudo hostapd /etc/hostapd/hostapd.conf & sudo dhclient -d br0 & sudo ifconfig wlan0 192.168.1.15 netmask 255.255.255.0 up sudo brctl addif br0 wlan0 These commands enable me to access internet on my wireless clients and also on the laptop which is acting as wireless accesspoint. But if I reboot the wired router (without rebooting the laptop that is acting as accesspoint), Internet access on the laptop+accesspoint gets lost, but on wireless clients it works fine. Even I have not been able to figure out a command which will reset the laptop interfaces to default settings, so everytime the router reboots, I have to reboot the laptop too to get into default settings so that I can re-enter the above mentioned commands. My first question is How can I have my bridge+accesspoint up and running even-though the router reboots? And is there a command to set the interfaces to a default state? (ifdown -a doesn't work, after issuing the command the bridge still remained).

(ifdown -a doesn't work, after issuing the command the bridge still remained).

• configs for several sites in apache with ssl

  - by elCapitano

  i need to secure two different sites in apache. One of them should only be a proxy for a different server which is running on port 8069. Now one (which is natively included in apache) runs with SSL: <VirtualHost *:443> ServerName 192.168.1.20 SSLEngine on SSLCertificateFile /etc/ssl/erp/oeserver.crt SSLCertificateKeyFile /etc/ssl/erp/oeserver.key DocumentRoot /var/www/cloud ServerPath /cloud/ #CustomLog /var/www/logs/ssl-access_log combined #ErrorLog /var/www/logs/ssl-error_log </VirtualHost> The other one is not running and even not registered. When i try to access it, i get an exception (ssl_error_rx_record_too_long): <VirtualHost *:443> ServerName 192.168.1.20 ServerPath /erp/ SSLEngine on SSLCertificateFile /etc/ssl/erp/oeserver.crt SSLCertificateKeyFile /etc/ssl/erp/oeserver.key ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyVia On ProxyPass / http://127.0.0.1:8069/ ProxyPassReverse / http://127.0.0.1:8069 RewriteEngine on RewriteRule ^/(.*) http://127.0.0.1:8069/$1 [P] RequestHeader set "X-Forwarded-Proto" "https" SetEnv proxy-nokeepalive 1 </VirtualHost> My whish is the following configuration: 192.168.1.20 ->> unsecured local path to website 192.168.1.20/cloud/ ->> secured local documentpath from cloud 192.168.1.20/erp/ ->> secured proxy on port 80 for http://192.168.1.20:8069 how is this possible? is this even possible? perhaps cloud.192.168.1.20 and erp.192.168.1.20 is better?!

• Why isn't 'Low Fragmentation Heap' LFH enabled by default on Windows Server 2003?

  - by James Wiseman

  I've been investigating an issue with a production Classic ASP website running on IIS6 which seems indicative of memory fragmentation. One of the suggestions of how to ameliorate this came from Stackoverflow: How can I find why some classic asp pages randomly take a real long time to execute?. It suggested flipping a setting in the site's global.asa file to 'turn on' Low Fragmentation Heap (LFH). The following code (with a registered version of the accompanying DLL) did the trick. Set LFHObj=CreateObject("TURNONLFH.ObjTurnOnLFH") LFHObj.TurnOnLFH() application("TurnOnLFHResult")=CStr(LFHObj.TurnOnLFHResult) (Really the code isn't that important to the question). An author of a linked post reported a seemingly magic resolution to this issue, and, reading around a little more, I discovered that this setting is enabled by default on Windows Server 2008. So, naturally, this left me a little concerned: Why is this setting not enabled by default on 2003, or If it works in 2008 why have Microsoft not issued a patch to enable it by default on 2003? I suspect the answer to the above is the same for both (if there is one). Obviously, we're testing it in a non-production environment, and doing an array of metrics and comparisons to deem if it does help us. But aside from this I'm really just trying to understand if there's any technical reason why we should do this, or if there are any gotchas that we need to be aware of.

• iptables to block non-VPN-traffic if not through tun0

  - by dacrow

  I have a dedicated Webserver running Debian 6 and some Apache, Tomcat, Asterisk and Mail-stuff. Now we needed to add VPN support for a special program. We installed OpenVPN and registered with a VPN provider. The connection works well and we have a virtual tun0 interface for tunneling. To archive the goal for only tunneling a single program through VPN, we start the program with sudo -u username -g groupname command and added a iptables rule to mark all traffic coming from groupname iptables -t mangle -A OUTPUT -m owner --gid-owner groupname -j MARK --set-mark 42 Afterwards we tell iptables to to some SNAT and tell ip route to use special routing table for marked traffic packets. Problem: if the VPN failes, there is a chance that the special to-be-tunneled program communicates over the normal eth0 interface. Desired solution: All marked traffic should not be allowed to go directly through eth0, it has to go through tun0 first. I tried the following commands which didn't work: iptables -A OUTPUT -m owner --gid-owner groupname ! -o tun0 -j REJECT iptables -A OUTPUT -m owner --gid-owner groupname -o eth0 -j REJECT It might be the problem, that the above iptable-rules didn't work due to the fact, that the packets are first marked, then put into tun0 and then transmitted by eth0 while they are still marked.. I don't know how to de-mark them after in tun0 or to tell iptables, that all marked packet may pass eth0, if they where in tun0 before or if they going to the gateway of my VPN provider. Does someone has any idea to a solution? Some config infos: iptables -nL -v --line-numbers -t mangle Chain OUTPUT (policy ACCEPT 11M packets, 9798M bytes) num pkts bytes target prot opt in out source destination 1 591K 50M MARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 MARK set 0x2a 2 82812 6938K CONNMARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 CONNMARK save iptables -nL -v --line-numbers -t nat Chain POSTROUTING (policy ACCEPT 393 packets, 23908 bytes) num pkts bytes target prot opt in out source destination 1 15 1052 SNAT all -- * tun0 0.0.0.0/0 0.0.0.0/0 mark match 0x2a to:VPN_IP ip rule add from all fwmark 42 lookup 42 ip route show table 42 default via VPN_IP dev tun0

• MX setup for a domain registrar and web host with the same domain name

  - by Honus Wagner

  I have a client that has registered their domain through a registrar, then signed up for hosting on through a different provider, but used the same domain for said provider (didn't re-register the domain, I think the declaration of domain on the host was for CNAME records specifically). The registrar properly routes his emails at his domain name (email hosted by Google), but the problem is, on the hosted site, when an administration action occurs, he is supposed to get an email stating so. The site is sending him an email with PHP and he never receives an email when its to his address with the same domain name; all other domain addresses work just fine. I have to imagine its something misconfigured on the host. From what I can assume, I think that the host sees that the to and from domains are the same, and it decides not to route the email externally. Currently, the registrar uses the proper nameservers for the host, and there are MX records on both the registrar and the host (they are identical entries). I hope I've been clear in my question. If you need further clarification, or additional information of any kind, I can provide it. Thanks in advance.

• conflicting info about the running kernel version in FreeBSD

  - by John

  I asked a related question about uname before, now want to ask from another angle because the following simple yet obvious conflicting outputs may mean there is something many people did not think of (me included). I'm running FreeBSD 9 RELEASE, please see the following commands: # sysctl kern.bootfile kern.bootfile: /boot/kernel/kernel # strings /boot/kernel/kernel |grep RELEASE|grep 9 @(#)FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 9.2-RELEASE-p7 The above kernel file suggests the running kernel is 9.2-RELEASE-p7. But... # dmesg Copyright (c) 1992-2012 The FreeBSD Project. Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 The Regents of the University of California. All rights reserved. FreeBSD is a registered trademark of The FreeBSD Foundation. FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 ... # uname -a FreeBSD localhost.localdomain 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 So dmesg and uname says it's 9.1-RELEASE. I also did an extensive find / -type f -exec grep -l "9.1-RELEASE" {} \; but found no possible kernel file that contains 9.1-RELEASE. What could lead to the above conflict, and what kernel I am actually running? Please note I run RELEASE and ran freebsd-update to do binary update, so no compiled kernel is involved. And I have rebooted multiple times after freebsd-update. And the system is not in jail etc, just the only system on that computer.

• Arch Linux: How to handle patches which only you will use?

  - by user12932

  I'm using freerdp together with xmonad and it has been giving me a lot of trouble. The super key (or "windows key") is my mod key in xmonad and it has been interfering with my freerdp usage rather annoyingly. Whenever I switched workspaces (or did anything else in xmonad involving the super key), windows (controlled by the freerdp instance in focus) registered a keypress as well. This event combined with the loss of focus got the super key stuck in windows indefinitely: the press of the keys d and r would first show my desktop, then open the run dialog (as if I was pressing the windows key constantly). I've tried several versions of freerdp, but all exhibited this annoying behavior. So I resorted to patching freerdp myself to just ignore the left super key on my keyboard. I love free software for a lot of reasons (especially the ability to alter things like this myself), however I still find it annoying to patch and rebuild freerdp on all version (and dependency) changes. How do you deal with situations like this? Is there even a "right way" to resolve this issue?
