• Can't launch glassfish on ec2 - can't open port

  - by orange80

  I'm trying to start glassfish on an EBS-based AMI of Ubuntu 10.04 64-bit. I have used glassfish on non-ec2 servers with no problems, but on ec2 I get this message: $ sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server. Command start-domain failed. I know that ec2 has requires that firewall rules be modified using ec2-authorize to let outside traffic thru the firewall, as I had to do to make ssh work. This still doesn't explain the port error when all I'm trying to do is start glassfish so I can try $ wget localhost:8080and make sure it's working. This is very frustrating and I'd really appreciate any help. Thanks. FINAL UPDATE: Sorry if you came here looking for answers. I never figured out what was causing the problem. I created another fresh instance, installed the same stuff, and Glassfish worked perfectly. Something obviously got boned during installation, but I have no idea what. I guess it will remain a mystery. UPDATE: Here's what I get from netstat: # netstat -nuptl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 462/sshd tcp6 0 0 :::22 :::* LISTEN 462/sshd udp 0 0 0.0.0.0:5353 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:1194 0.0.0.0:* 589/openvpn udp 0 0 0.0.0.0:37940 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:68 0.0.0.0:* 377/dhclient3 UPDATE: One more thing... I know that the "net.ipv6.bindv6only" kernel option can cause problems with java networking, so I did set this: # sysctl -w net.ipv6.bindv6only=0 UPDATE: I also verified that it has nothing at all to do with the port number (4848). As you can see here, when I changed the admin-listener port in domain.xml to 4949, I get a similar message: # sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4949 -- it probably is another instance of a GlassFish server. Command start-domain failed. UPDATE: Here are the contents of /etc/hosts: 127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts I should mention that I have another Ubuntu Lucid 10.04 64-bit slice that is NOT hosted on ec2, and set it up the exact same way with no problems whatsoever. Also server.log doesn't offer much insight either: # cat ./server.log Nov 20, 2010 8:46:49 AM com.sun.enterprise.admin.launcher.GFLauncherLogger info INFO: JVM invocation command line: /usr/lib/jvm/java-6-sun-1.6.0.22/bin/java -cp /opt/glassfishv3/glassfish/modules/glassfish.jar -XX:+UnlockDiagnosticVMOptions -XX:MaxPermSize=192m -XX:NewRatio=2 -XX:+LogVMOutput -XX:LogFile=/opt/glassfishv3/glassfish/domains/domain1/logs/jvm.log -Xmx512m -client -javaagent:/opt/glassfishv3/glassfish/lib/monitor/btrace-agent.jar=unsafe=true,noServer=true -Dosgi.shell.telnet.maxconn=1 -Djdbc.drivers=org.apache.derby.jdbc.ClientDriver -Dfelix.fileinstall.dir=/opt/glassfishv3/glassfish/modules/autostart/ -Djavax.net.ssl.keyStore=/opt/glassfishv3/glassfish/domains/domain1/config/keystore.jks -Dosgi.shell.telnet.port=6666 -Djava.security.policy=/opt/glassfishv3/glassfish/domains/domain1/config/server.policy -Dfelix.fileinstall.poll=5000 -Dcom.sun.aas.instanceRoot=/opt/glassfishv3/glassfish/domains/domain1 -Dcom.sun.enterprise.config.config_environment_factory_class=com.sun.enterprise.config.serverbeans.AppserverConfigEnvironmentFactory -Dosgi.shell.telnet.ip=127.0.0.1 -Djava.endorsed.dirs=/opt/glassfishv3/glassfish/modules/endorsed:/opt/glassfishv3/glassfish/lib/endorsed -Dcom.sun.aas.installRoot=/opt/glassfishv3/glassfish -Djava.ext.dirs=/usr/lib/jvm/java-6-sun-1.6.0.22/lib/ext:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/ext:/opt/glassfishv3/glassfish/domains/domain1/lib/ext -Dfelix.fileinstall.bundles.new.start=true -Djavax.net.ssl.trustStore=/opt/glassfishv3/glassfish/domains/domain1/config/cacerts.jks -Dcom.sun.enterprise.security.httpsOutboundKeyAlias=s1as -Djava.security.auth.login.config=/opt/glassfishv3/glassfish/domains/domain1/config/login.conf -DANTLR_USE_DIRECT_CLASS_LOADING=true -Dfelix.fileinstall.debug=1 -Dorg.glassfish.web.rfc2109_cookie_names_enforced=false -Djava.library.path=/opt/glassfishv3/glassfish/lib:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64/server:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64:/usr/lib/jvm/java-6-sun-1.6.0.22/lib/amd64:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib com.sun.enterprise.glassfish.bootstrap.ASMain -domainname domain1 -asadmin-args start-domain,,,domain1 -instancename server -verbose false -debug false -asadmin-classpath /opt/glassfishv3/glassfish/modules/admin-cli.jar -asadmin-classname com.sun.enterprise.admin.cli.AsadminMain -upgrade false -domaindir /opt/glassfishv3/glassfish/domains/domain1 -read-stdin true

• WSUS 3.0 SP2 installation fails at "configuring database" step.

  - by flashkube

  Attempting to install WSUS 3.0 SP2 on a Windows Server 2003 Enterprise system. I'm asking the setup to create a new database on one of our existing SQL Server 2005 systems. When the setup gets to the "configuring database" step it stops and throws "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." The two logs it suggests I look at are below. I'm not seeing any errors that mean anything to me. Any direction you can give will be greatly appreciated.

• Kernel panic when bringing up DRBD resource

  - by sc.

  I'm trying to set up two machines synchonizing with DRBD. The storage is setup as follows: PV - LVM - DRBD - CLVM - GFS2. DRBD is set up in dual primary mode. The first server is set up and running fine in primary mode. The drives on the first server have data on them. I've set up the second server and I'm trying to bring up the DRBD resources. I created all the base LVM's to match the first server. After initializing the resources with `` drbdadm create-md storage I'm bringing up the resources by issuing drbdadm up storage After issuing that command, I get a kernel panic and the server reboots in 30 seconds. Here's a screen capture. My configuration is as follows: OS: CentOS 6 uname -a Linux host.structuralcomponents.net 2.6.32-279.5.2.el6.x86_64 #1 SMP Fri Aug 24 01:07:11 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux rpm -qa | grep drbd kmod-drbd84-8.4.1-2.el6.elrepo.x86_64 drbd84-utils-8.4.1-2.el6.elrepo.x86_64 cat /etc/drbd.d/global_common.conf global { usage-count yes; # minor-count dialog-refresh disable-ip-verification } common { handlers { pri-on-incon-degr "/usr/lib/drbd/notify-pri-on-incon-degr.sh; /usr/lib/drbd/notify-emergency-reboot.sh; echo b /proc/sysrq-trigger ; reboot -f"; pri-lost-after-sb "/usr/lib/drbd/notify-pri-lost-after-sb.sh; /usr/lib/drbd/notify-emergency-reboot.sh; echo b /proc/sysrq-trigger ; reboot -f"; local-io-error "/usr/lib/drbd/notify-io-error.sh; /usr/lib/drbd/notify-emergency-shutdown.sh; echo o /proc/sysrq-trigger ; halt -f"; # fence-peer "/usr/lib/drbd/crm-fence-peer.sh"; # split-brain "/usr/lib/drbd/notify-split-brain.sh root"; # out-of-sync "/usr/lib/drbd/notify-out-of-sync.sh root"; # before-resync-target "/usr/lib/drbd/snapshot-resync-target-lvm.sh -p 15 -- -c 16k"; # after-resync-target /usr/lib/drbd/unsnapshot-resync-target-lvm.sh; } startup { # wfc-timeout degr-wfc-timeout outdated-wfc-timeout wait-after-sb become-primary-on both; wfc-timeout 30; degr-wfc-timeout 10; outdated-wfc-timeout 10; } options { # cpu-mask on-no-data-accessible } disk { # size max-bio-bvecs on-io-error fencing disk-barrier disk-flushes # disk-drain md-flushes resync-rate resync-after al-extents # c-plan-ahead c-delay-target c-fill-target c-max-rate # c-min-rate disk-timeout } net { # protocol timeout max-epoch-size max-buffers unplug-watermark # connect-int ping-int sndbuf-size rcvbuf-size ko-count # allow-two-primaries cram-hmac-alg shared-secret after-sb-0pri # after-sb-1pri after-sb-2pri always-asbp rr-conflict # ping-timeout data-integrity-alg tcp-cork on-congestion # congestion-fill congestion-extents csums-alg verify-alg # use-rle protocol C; allow-two-primaries yes; after-sb-0pri discard-zero-changes; after-sb-1pri discard-secondary; after-sb-2pri disconnect; } } cat /etc/drbd.d/storage.res resource storage { device /dev/drbd0; meta-disk internal; on host.structuralcomponents.net { address 10.10.1.120:7788; disk /dev/vg_storage/lv_storage; } on host2.structuralcomponents.net { address 10.10.1.121:7788; disk /dev/vg_storage/lv_storage; } /var/log/messages is not logging anything about the crash.

• Unable to connect to OpenVPN server

  - by Incognito

  I'm trying to get a working setup of OpenVPN on my VM and authenticate into it from a client. I'm not sure but it looks to me like it's socket related, as it's not set to LISTEN, and localhost seems wrong. I've never set up VPN before. # netstat -tulpn | grep vpn Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 0 0 127.0.0.1:1194 0.0.0.0:* 24059/openvpn I don't think this is set up correctly.

On the client-side I've installed the p12 certs onto two devices (one is an android tablet, the other is an Ubuntu desktop). I don't see port 1194 as open either. Both clients install the cert files and then ask me for the L2TP secret (which was set on the file), but then they oddly ask me for a username and a password, which I don't know where I could possibly get those from. I attempted all of my logins, and some whacky guesses that were frantically pulling at straws. If there's any more information I could provide let me know.

• How can I recreate root dnsNode objects and their RootDNSServers folder in AD after they are deleted?

  - by TonyD

  A few days ago I was trying to permanently remove root hints from my DNS server. After much ado, I decided to go a different route and am now trying to put everything back as it was. During the original process, I opened ADUC, clicked ViewAdvanced Features, and then browsed to System MicrosoftDNS and deleted the folder RootDNSServers. Now in ADUC, I cannot create a folder here to replace the one I deleted. I can run adsiedit and load DomainDNSZones for my domain. Under there, I see MicrosoftDNS, RootDNSServers, with all of the objects still inside of it. Is there a way for me to undo what I did? Can I recreate these objects in ADUC? Can I do something else to cause them to show back up there? Thanks!

• Postfix MySql Dovecot - SMTP Authentication Failure

  - by borncamp

  Hello I have a Postfix setup with Dovecot and MySql. The server is running Debian Squeeze. The MySql server is a slave that has data pushed to it from a primary (postfix) mail server(running a different os). The emails are stored on a replicated GlusterFS volume. I am able to check email using thunderbird over IMAP. However, SMTP requests fail. After turning on query logs for the MySql server I have noticed that no query statement is executed to retrieve the user information when an SMTP client tries to authenticate.

• How to setup certificate authentication for MS SQL server 2008 R2 ?

  - by Stephane

  Hello, I have to connect an (ADO) application running on a standalone Windows 2003 R2 server to a SQL 2008 R2 database that is a member of the domain. I have setup an SQL authentication account for this and hard-coded the password into the connection string but I wonder if it wouldn't be possible to use certificate-based authentication for this instead. I haven't been able to find any documentation regarding this apparently new functionality of SQL 2008 R2 anywhere. Could someone kindly point me at some good documentation ? Or at least a description of the functionality and whether it could be used in my case or not ? Thank you in advance

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

  - by user135501

  I'm in DMZ mode, so I'm firewalling myself, stealthy all ok, but I get faulty test results from Shields Up that there are pings. Yesterday I couldn't make a connection to game servers work, because ping block was enabled (on the router). I disabled it, but this persists even due to my firewall. What is the connection between me and my router in DMZ mode (for my machine, there is bunch of others too behind router firewall)? When it allows router affecting if I'm pingable or not and if router has setting not blocking ping, rules in my iptables for this scenario do not work. Please ignore commented rules, I do uncomment them as I want.

• cannot send mail to postfix /w iptables linux proxy

  - by Juzzam

  I have two separate servers, both running Ubuntu 8.04. Server 1 has the real domain name of our site, let's refer to it as example.com. Server 2 is a mail server I have setup with postfix/courier. The hostname for this server is mail.example.com. I've setup iptables on Server 1 to forward all traffic on port 25 to Server 2. I used this script (except I changed the target ip address and the port from 80 to 25). When I send an email to [email protected] it works. However, when I try to send an email to [email protected] from gmail, I get this error: 550 550 #5.1.0 Address rejected [email protected] (state 14) /var/log/mail.log shows no new lines when this happens.

• Kill Leaking Connections on SQL Server 2005

  - by Thierry Brunet

  We have a legacy ASP application that somewhere leaks SQL Connections. In Activity Monitor, I can see a bunch of idle processes with Last Batch times over an hour old. When I look at the T-SQL command batch, these are always FETCH API_CURSORXXX, which from my understanding is caused by improperly closed ASP ADO Recordsets. While we are try to pinpoint the offeding code, is there a way for me to monitor which requests open which cursors? I'm assuming profiler, but I'm not sure what I should be monitoring exactly. I can see a bunch of calls to sp_cursoropen but I don't see the API_CUSORXXX name anywhere. Second, would anyone be able to suggest a script we could run to kill these processes based on the Last Batch time 10 minutes and Last Batch Command being FETCH API_CURSORXXX? For various reasons, we unfortunately don't have any SQL Server DBAs.

• Login sometimes failing immediately after restoring a database

  - by Ian Ringrose

  We have a set of automated tests that restore a database then run some .net code against the database. Sometimes after the database is restored the login from Ado.net fails. If I re-run the test, then the restore and login works OK. The restored database looks OK when viewed with Management Studio. This is only an problem on some machines. We are using SQL server 2008. Is there a known issue with a database restore “returning “ a very short time before the restored database is up and running.

• Wi-Fi Stick with ZD1211 chip refuses to work on Ubuntu >8.10. No clue.

  - by Benjamin Maus

  I have a machine running Ubuntu 9.10 (Karmic *x86_64*). Everything is running smooth so far, except for the Wi-Fi USB Stick. The same device worked perfectly in 8.10. The wireless device is a GW-US54GXS using the Zydas Zd1211 chipset. Dmesg output after plugging in: [ 196.303436] phy0: Selected rate control algorithm 'minstrel' [ 196.304209] zd1211rw 2-1:1.0: phy0 [ 196.304227] usbcore: registered new interface driver zd1211rw [ 196.334137] usb 2-1: firmware: requesting zd1211/zd1211b_ub [ 196.357463] usb 2-1: firmware: requesting zd1211/zd1211b_uphr [ 196.402643] zd1211rw 2-1:1.0: firmware version 4725 [ 196.442611] zd1211rw 2-1:1.0: zd1211b chip 2019:5303 v4810 high 00-90-cc AL2230_RF pa0 ---N- [ 196.463814] usb 2-1: firmware: requesting zd1211/zd1211b_ub [ 196.466823] usb 2-1: firmware: requesting zd1211/zd1211b_uphr Syslog output: Nov 5 11:20:24 somesystem kernel: [ 196.303436] phy0: Selected rate control algorithm 'minstrel' Nov 5 11:20:24 kierkegaard NetworkManager: <info> Found radio killswitch rfkill0 (at /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-1/2-1:1.0/ieee80211/phy0/rfkill0) (driver <unknown>) Nov 5 11:20:24 somesystem kernel: [ 196.304209] zd1211rw 2-1:1.0: phy0 Nov 5 11:20:24 somesystem kernel: [ 196.304227] usbcore: registered new interface driver zd1211rw Nov 5 11:20:24 somesystem NetworkManager: SCPlugin-Ifupdown: devices added (path: /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-1/2-1:1.0/net/wmaster0, iface: wmaster0) Nov 5 11:20:24 somesystem NetworkManager: SCPlugin-Ifupdown: device added (path: /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-1/2-1:1.0/net/wmaster0, iface: wmaster0): no ifupdown configuration found.

• Unable to update the EntitySet because it has a DefiningQuery and no &lt;UpdateFunction&gt; element

  - by Harish Ranganathan

  When working with ADO.NET Entity Data Model, its often common that we generate entity schema for more than a single table from our Database.  With Entity Model generation automated with Visual Studio support, it becomes even tempting to create and work entity models to achieve an object mapping relationship. One of the errors that you might hit while trying to update an entity set either programmatically using context.SaveChanges or while using the automatic insert/update code generated by GridView etc., is “Unable to update the EntitySet <EntityName> because it has a DefiningQuery and no <UpdateFunction> element exists in the <ModificationFunctionMapping> element to support the current operation” While the description is pretty lengthy, the immediate thing that would come to our mind is to open our the entity model generated code and see if you can update it accordingly. However, the first thing to check if that, if the Entity Set is generated from a table, whether the Table defines a primary key.  Most of the times, we create tables with primary keys.  But some reference tables and tables which don’t have a primary key cannot be updated using the context of Entity and hence it would throw this error.  Unless it is a View, in which case, the default model is read-only, most of the times the above error occurs since there is no primary key defined in the table. There are other reasons why this error could popup which I am not going into for the sake of simplicity of the post.  If you find something new, please feel free to share it in comments. Hope this helps. Cheers !!!

• #twitter for Windows Phone 7 protips (#wp7)

  - by Laurent Bugnion

  I started tweeting a list of “protips” (or whatever you want to call that) related to the Twitter for Windows Phone 7 application. Since I worked as integrator on this app, my tasks involved integrating design assets in all screens, and so I had an insider view on all the screens (and that is really a LOT of screens :) Seeing some comments about the app made me understand that most users out there don’t realize how rich the application is, and how many features are available. So without further ado, here we go, a list of Twitter for WP7 protips: (note: I will extend the list if I think of new stuff, and maybe add some screenshots later). Check the dark theme in the application settings! Select a tweet, menu, Translate. Search, Nearby looks for tweets near you Custom searches can be saved. They synch up with web twitter too! Multi language support, independant from OS. supports EN, FR, DE, IT, ES Multiple accounts are supported, simply define them in the Settings Even without a Twitter account, experience is super rich. Trends, Suggested, Nearby, searches etc... Select a tweet, then press Replies To to see the whole conversation Compose, menu, Hashtags. Enter a hashtag and press Add. List is saved for the next time. Select a tweet with location info (like my own). Press the location name to see all Nearby tweets Want to remove location information just for one tweet? Press on the Places button in app bar then Clear Place Settings, General to toggle between Username/Fullname display, Relative/Absolute date/time and more Upload a picture directly from compose screen to TwitPic, yFrog or TweetPhoto (service selection in Settings) Settings, About, Support to see a log of app errors and email it to support (use wisely please) Tap your username to see your profile. Then Menu, Edit Profile to edit your info, including your picture Tap on any user's name to see his profile, tweets, mentions and favorites in a Pivot Happy Tweeting!

• Faye private pub web sockets Errno::ECONNREFUSED: Connection refused - connect(2)

  - by Rubytastic

• On StringComparison Values

  - by Jesse

  When you use the .NET Framework’s String.Equals and String.Compare methods do you use an overloStringComparison enumeration value? If not, you should be because the value provided for that StringComparison argument can have a big impact on the results of your string comparison. The StringComparison enumeration defines values that fall into three different major categories: Culture-sensitive comparison using a specific culture, defaulted to the Thread.CurrentThread.CurrentCulture value (StringComparison.CurrentCulture and StringComparison.CurrentCutlureIgnoreCase) Invariant culture comparison (StringComparison.InvariantCulture and StringComparison.InvariantCultureIgnoreCase) Ordinal (byte-by-byte) comparison of  (StringComparison.Ordinal and StringComparison.OrdinalIgnoreCase) There is a lot of great material available that detail the technical ins and outs of these different string comparison approaches. If you’re at all interested in the topic these two MSDN articles are worth a read: Best Practices For Using Strings in the .NET Framework: http://msdn.microsoft.com/en-us/library/dd465121.aspx How To Compare Strings: http://msdn.microsoft.com/en-us/library/cc165449.aspx Those articles cover the technical details of string comparison well enough that I’m not going to reiterate them here other than to say that the upshot is that you typically want to use the culture-sensitive comparison whenever you’re comparing strings that were entered by or will be displayed to users and the ordinal comparison in nearly all other cases. So where does that leave the invariant culture comparisons? The “Best Practices For Using Strings in the .NET Framework” article has the following to say: “On balance, the invariant culture has very few properties that make it useful for comparison. It does comparison in a linguistically relevant manner, which prevents it from guaranteeing full symbolic equivalence, but it is not the choice for display in any culture. One of the few reasons to use StringComparison.InvariantCulture for comparison is to persist ordered data for a cross-culturally identical display. For example, if a large data file that contains a list of sorted identifiers for display accompanies an application, adding to this list would require an insertion with invariant-style sorting.” I don’t know about you, but I feel like that paragraph is a bit lacking. Are there really any “real world” reasons to use the invariant culture comparison? I think the answer to this question is, “yes”, but in order to understand why we should first think about what the invariant culture comparison really does. The invariant culture comparison is really just a culture-sensitive comparison using a special invariant culture (Michael Kaplan has a great post on the history of the invariant culture on his blog: http://blogs.msdn.com/b/michkap/archive/2004/12/29/344136.aspx). This means that the invariant culture comparison will apply the linguistic customs defined by the invariant culture which are guaranteed not to differ between different machines or execution contexts. This sort of consistently does prove useful if you needed to maintain a list of strings that are sorted in a meaningful and consistent way regardless of the user viewing them or the machine on which they are being viewed. Example: Prototype Names Let’s say that you work for a large multi-national toy company with branch offices in 10 different countries. Each year the company would work on 15-25 new toy prototypes each of which is assigned a “code name” while it is under development. Coming up with fun new code names is a big part of the company culture that everyone really enjoys, so to be fair the CEO of the company spent a lot of time coming up with a prototype naming scheme that would be fun for everyone to participate in, fair to all of the different branch locations, and accessible to all members of the organization regardless of the country they were from and the language that they spoke. Each new prototype will get a code name that begins with a letter following the previously created name using the alphabetical order of the Latin/Roman alphabet. Each new year prototype names would start back at “A”. The country that leads the prototype development effort gets to choose the name in their native language. (An appropriate Romanization system will be used for countries where the primary language is not written in the Latin/Roman alphabet. For example, the Pinyin system could be used for Chinese). To avoid repeating names, a list of all current and past prototype names will be maintained on each branch location’s company intranet site. Assuming that maintaining a single pre-sorted list is not feasible among all of the highly distributed intranet implementations, what string comparison method would you use to sort each year’s list of prototype names so that the list is both meaningful and consistent regardless of the country within which the list is being viewed? Sorting the list with a culture-sensitive comparison using the default configured culture on each country’s intranet server the list would probably work most of the time, but subtle differences between cultures could mean that two different people would see a list that was sorted slightly differently. The CEO wants the prototype names to be a unifying aspect of company culture and is adamant that everyone see the the same list sorted in the same order and there’s no way to guarantee a consistent sort across different cultures using the culture-sensitive string comparison rules. The culture-sensitive sort would produce a meaningful list for the specific user viewing it, but it wouldn’t always be consistent between different users. Sorting with the ordinal comparison would certainly be consistent regardless of the user viewing it, but would it be meaningful? Let’s say that the current year’s prototype name list looks like this: Antílope (Spanish) Babouin (French) Cahoun (Czech) Diamond (English) Flosse (German) If you were to sort this list using ordinal rules you’d end up with: Antílope Babouin Diamond Flosse Cahoun This sort is no good because the entry for “C” appears the bottom of the list after “F”. This is because the Czech entry for the letter “C” makes use of a diacritic (accent mark). The ordinal string comparison does a byte-by-byte comparison of the code points that make up each character in the string and the code point for the “C” with the diacritic mark is higher than any letter without a diacritic mark, which pushes that entry to the bottom of the sorted list. The CEO wants each country to be able to create prototype names in their native language, which means we need to allow for names that might begin with letters that have diacritics, so ordinal sorting kills the meaningfulness of the list. As it turns out, this situation is actually well-suited for the invariant culture comparison. The invariant culture accounts for linguistically relevant factors like the use of diacritics but will provide a consistent sort across all machines that perform the sort. Now that we’ve walked through this example, the following line from the “Best Practices For Using Strings in the .NET Framework” makes a lot more sense: One of the few reasons to use StringComparison.InvariantCulture for comparison is to persist ordered data for a cross-culturally identical display That line describes the prototype name example perfectly: we need a way to persist ordered data for a cross-culturally identical display. While this example is 100% made-up, I think it illustrates that there are indeed real-world situations where the invariant culture comparison is useful.

• cannot connect with huawei e173 after upgrade to 12.10 using network manager

  - by user104195

  Since upgrade from 12.04 to 12.10 I can't connect to internet using mobile broadband modem Huawei e173. It worked earlier without problems and now it seems to be properly recognized (at least its connections appear in network manager applet), and after selecting connection manually it starts connection procedure. After about 20 seconds it returns to state disconnected. After browsing internet I've found that running network manager with: NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon After inserting modem I get: NetworkManager[507]: <warn> (ttyUSB2): failed to look up interface index NetworkManager[507]: <info> (ttyUSB2): new GSM/UMTS device (driver: 'option1' ifindex: 0) NetworkManager[507]: <info> (ttyUSB2): exported as /org/freedesktop/NetworkManager/Devices/2 NetworkManager[507]: <info> (ttyUSB2): now managed NetworkManager[507]: <info> (ttyUSB2): device state change: unmanaged -> unavailable (reason 'managed') [10 20 2] NetworkManager[507]: <info> (ttyUSB2): deactivating device (reason 'managed') [2] NetworkManager[507]: <info> (ttyUSB2): device state change: unavailable -> disconnected (reason 'none') [20 30 0] where 'failed to look up interface index' seems to be suspicious.

I've tried to downgrade network manager but failed due to many dependencies. Can anyone point me to solution or tell what should I do to further investigate the problem?

• C++ Mutexes and STL Lists Across Subclasses

  - by Genesis

  I am currently writing a multi-threaded C++ server using Poco and am now at the point where I need to be keeping information on which users are connected, how many connections each of them have, and given it is a proxy server, where each of those connections are proxying through to. For this purpose I have created a ServerStats class which holds an STL list of ServerUser objects. The ServerStats class includes functions which can add and remove objects from the list as well as find a user in the list an return a pointer to them so I can access member functions within any given ServerUser object in the list. The ServerUser class contains an STL list of ServerConnection objects and much like the ServerStats class it contains functions to add, remove and find elements within this list. Now all of the above is working but I am now trying to make it threadsafe. I have defined a Poco::FastMutex within the ServerStats class and can lock/unlock this in the appropriate places so that STL containers are not modified at the same time as being searched for example. I am however having an issue setting up mutexes within the ServerUser class and am getting the following compiler error: /root/poco/Foundation/include/Poco/Mutex.h: In copy constructor âServerUser::ServerUser(const ServerUser&)â: src/SocksServer.cpp:185: instantiated from âvoid __gnu_cxx::new_allocator<_Tp::construct(_Tp*, const _Tp&) [with _Tp = ServerUser]â /usr/include/c++/4.4/bits/stl_list.h:464: instantiated from âstd::_List_node<_Tp* std::list<_Tp, _Alloc::_M_create_node(const _Tp&) [with _Tp = ServerUser, _Alloc = std::allocator]â /usr/include/c++/4.4/bits/stl_list.h:1407: instantiated from âvoid std::list<_Tp, _Alloc::_M_insert(std::_List_iterator<_Tp, const _Tp&) [with _Tp = ServerUser, _Alloc = std::allocator]â /usr/include/c++/4.4/bits/stl_list.h:920: instantiated from âvoid std::list<_Tp, _Alloc::push_back(const _Tp&) [with _Tp = ServerUser, _Alloc = std::allocator]â src/SocksServer.cpp:301: instantiated from here /root/poco/Foundation/include/Poco/Mutex.h:164: error: âPoco::FastMutex::FastMutex(const Poco::FastMutex&)â is private src/SocksServer.cpp:185: error: within this context In file included from /usr/include/c++/4.4/x86_64-linux-gnu/bits/c++allocator.h:34, from /usr/include/c++/4.4/bits/allocator.h:48, from /usr/include/c++/4.4/string:43, from /root/poco/Foundation/include/Poco/Bugcheck.h:44, from /root/poco/Foundation/include/Poco/Foundation.h:147, from /root/poco/Net/include/Poco/Net/Net.h:45, from /root/poco/Net/include/Poco/Net/TCPServerParams.h:43, from src/SocksServer.cpp:1: /usr/include/c++/4.4/ext/new_allocator.h: In member function âvoid __gnu_cxx::new_allocator<_Tp::construct(_Tp*, const _Tp&) [with _Tp = ServerUser]â: /usr/include/c++/4.4/ext/new_allocator.h:105: note: synthesized method âServerUser::ServerUser(const ServerUser&)â first required here src/SocksServer.cpp: At global scope: src/SocksServer.cpp:118: warning: âstd::string getWord(std::string)â defined but not used make: * [/root/poco/SocksServer/obj/Linux/x86_64/debug_shared/SocksServer.o] Error 1 The code for the ServerStats, ServerUser and ServerConnection classes is below: class ServerConnection { public: bool continue_connection; int bytes_in; int bytes_out; string source_address; string destination_address; ServerConnection() { continue_connection = true; } ~ServerConnection() { } }; class ServerUser { public: string username; int connection_count; string client_ip; ServerUser() { } ~ServerUser() { } ServerConnection* addConnection(string source_address, string destination_address) { //FastMutex::ScopedLock lock(_connection_mutex); ServerConnection connection; connection.source_address = source_address; connection.destination_address = destination_address; client_ip = getWord(source_address, ":"); _connections.push_back(connection); connection_count++; return &_connections.back(); } void removeConnection(string source_address) { //FastMutex::ScopedLock lock(_connection_mutex); for(list<ServerConnection>::iterator it = _connections.begin(); it != _connections.end(); it++) { if(it->source_address == source_address) { it = _connections.erase(it); connection_count--; } } } void disconnect() { //FastMutex::ScopedLock lock(_connection_mutex); for(list<ServerConnection>::iterator it = _connections.begin(); it != _connections.end(); it++) { it->continue_connection = false; } } list<ServerConnection>* getConnections() { return &_connections; } private: list<ServerConnection> _connections; //UNCOMMENTING THIS LINE BREAKS IT: //mutable FastMutex _connection_mutex; }; class ServerStats { public: int current_users; ServerStats() { current_users = 0; } ~ServerStats() { } ServerUser* addUser(string username) { FastMutex::ScopedLock lock(_user_mutex); for(list<ServerUser>::iterator it = _users.begin(); it != _users.end(); it++) { if(it->username == username) { return &(*it); } } ServerUser newUser; newUser.username = username; _users.push_back(newUser); current_users++; return &_users.back(); } void removeUser(string username) { FastMutex::ScopedLock lock(_user_mutex); for(list<ServerUser>::iterator it = _users.begin(); it != _users.end(); it++) { if(it->username == username) { _users.erase(it); current_users--; break; } } } ServerUser* getUser(string username) { FastMutex::ScopedLock lock(_user_mutex); for(list<ServerUser>::iterator it = _users.begin(); it != _users.end(); it++) { if(it->username == username) { return &(*it); } } return NULL; } private: list<ServerUser> _users; mutable FastMutex _user_mutex; }; Now I have never used C++ for a project of this size or mutexes for that matter so go easy please :) Firstly, can anyone tell me why the above is causing a compiler error? Secondly, can anyone suggest a better way of storing the information I require? Bear in mind that I need to update this info whenever connections come or go and it needs to be global to the whole server.
