• Show Notes: Getting Past the Cloud Hype

  - by Bob Rhubart

  This week’s ArchBeat podcast features an unvarnished bit of conversation culled from a recent virtual meet-up. These meet-ups are informal conversations among architects, many of who have participated in previous ArchBeat programs. There’s no prearranged topic, so the participants talk about whatever is on their minds. The most recent meet-up included Oracle ACE Director Ran Batra, director of cloud computing product development with AT&T, and Daniel Templeton, principal product manager for Oracle Grid Engine, and the man behind Dan T’s GridBlog. The conversation took place at the end of the year – and the end of the decade – a time when most tech publications feature their predictions for the coming year.  I wanted a different spin on that theme, so I asked Ron and Dan to talk about the technologies about which they weren’t all that optimistic.   I found that ten-minute chunk of conversation particularly interesting, so that’s what you’re going to hear this week. Listen Get Social If you have questions or comment for Ron and/or Daniel you can connect via the following: Ron Batra Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Daniel Templeton Blog | Twitter | LinkedIn Coming Up Oracle ACE Director Debra Lilley talks about her role in the UKOUG’s development group and that group’s collaboration with Oracle on Oracle Fusion Applications.

• Swap partition not recognized (The disk drive with UUID=... is not ready yet or not present)

  - by ladaghini

  I think I had an encrypted swap partition, because I chose to encrypt my home directory during the installation. I believe that's what the line with /dev/mapper/cryptswap1 ... in my /etc/fstab is all about. I did something to bork my swap because on the next boot, I got a message (paraphrased): The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present. Wait to continue. Press S to skip or M to manually recover. (As a side note, pressing S or M seemed to do nothing different from just waiting.) Here's what I've tried: This tutorial on how to fix the swap partition not mounting. However, in the above, the mkswap command fails because the device is busy. So I booted from a live USB, ran GParted to reformat the swap partition (which showed up as an unknown fs type), and chrooted into the broken system to try that tutorial again. I also adjusted /etc/initramfs-tools/conf.d/resume and /etc/fstab to reflect the new UUID generated from formatting the partition as a swap. That still didn't work; instead of /dev/mapper/cryptswap1 not present, "The disk drive with UUID=[swap partition's UUID] is not ready yet or not present..." So I decided to start afresh as though I never had created a swap partition in the first place. From the Live USB, I deleted the swap partition altogether (which, again showed up in GParted as an unknown fs type), removed the swap and cryptswap entries in /etc/fstab as well as removed /etc/initramfs-tools/conf.d/resume and /etc/crypttab. At this point the main system shouldn't be considered broken because there is no swap partition and no instructions to mount one, right? I didn't get any errors during startup. I followed the same instructions to create and encrypt the swap partition, starting with creating a partition for the swap, though I think fdisk said a reboot was necessary to see changes. I was confident the 3rd process above would work, but the problem yet persists. Some relevant info (/dev/sda8 is the swap partition): /etc/fstab file: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda6 during installation UUID=4c11e82c-5fe9-49d5-92d9-cdaa6865c991 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda5 during installation UUID=4031413e-e89f-49a9-b54c-e887286bb15e /boot ext4 defaults 0 2 # /home was on /dev/sda7 during installation UUID=d5bbfc6f-482a-464e-9f26-fd213230ae84 /home ext4 defaults 0 2 # swap was on /dev/sda8 during installation UUID=5da2c720-8787-4332-9317-7d96cf1e9b80 none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 output of sudo mount: /dev/sda6 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) /dev/sda5 on /boot type ext4 (rw) /dev/sda7 on /home type ext4 (rw) /home/undisclosed/.Private on /home/undisclosed type ecryptfs (ecryptfs_check_dev_ruid,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs,ecryptfs_sig=cbae1771abd34009,ecryptfs_fnek_sig=7cefe2f59aab8e58) gvfs-fuse-daemon on /home/undisclosed/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=undisclosed) output of sudo blkid (note that /dev/sda8 is missing): /dev/sda1: LABEL="SYSTEM" UUID="960490E80490CC9D" TYPE="ntfs" /dev/sda2: UUID="D4043140043126C0" TYPE="ntfs" /dev/sda3: LABEL="Shared" UUID="80F613E1F613D5EE" TYPE="ntfs" /dev/sda5: UUID="4031413e-e89f-49a9-b54c-e887286bb15e" TYPE="ext4" /dev/sda6: UUID="4c11e82c-5fe9-49d5-92d9-cdaa6865c991" TYPE="ext4" /dev/sda7: UUID="d5bbfc6f-482a-464e-9f26-fd213230ae84" TYPE="ext4" /dev/mapper/cryptswap1: UUID="41fa147a-3e2c-4e61-b29b-3f240fffbba0" TYPE="swap" output of sudo fdisk -l: Disk /dev/mapper/cryptswap1 doesn't contain a valid partition table Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xdec3fed2 Device Boot Start End Blocks Id System /dev/sda1 * 2048 409599 203776 7 HPFS/NTFS/exFAT /dev/sda2 409600 210135039 104862720 7 HPFS/NTFS/exFAT /dev/sda3 210135040 415422463 102643712 7 HPFS/NTFS/exFAT /dev/sda4 415424510 625141759 104858625 5 Extended /dev/sda5 415424512 415922175 248832 83 Linux /dev/sda6 415924224 515921919 49998848 83 Linux /dev/sda7 515923968 621389823 52732928 83 Linux /dev/sda8 621391872 625141759 1874944 82 Linux swap / Solaris Disk /dev/mapper/cryptswap1: 1919 MB, 1919942656 bytes 255 heads, 63 sectors/track, 233 cylinders, total 3749888 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xaf5321b5 /etc/initramfs-tools/conf.d/resume file: RESUME=UUID=5da2c720-8787-4332-9317-7d96cf1e9b80 /etc/crypttab file: cryptswap1 /dev/sda8 /dev/urandom swap,cipher=aes-cbc-essiv:sha256 output of sudo swapon -as: Filename Type Size Used Priority /dev/mapper/cryptswap1 partition 1874940 0 -1 output of sudo free -m: total used free shared buffers cached Mem: 1476 1296 179 0 35 671 -/+ buffers/cache: 590 886 Swap: 1830 0 1830 So, how can this be fixed?

• Reliable access to Internet but not local network (not DNS or proxy issues)

  - by Ian Goldby

  I'm looking for help with a Vista Home Premium laptop that has trouble accessing any resource on our home network, but accesses the Internet just fine. The set-up is this: The Vista laptop and a MacBook Pro connect wirelessly to the router-modem. A Synology DS212j NAS drive has a wired connection to the router-modem. Devices on the local network are always referred to by IP address, so this cannot be a DNS issue. The MacBook Pro connects reliably to the NA via AFP (network shared folders), SMB (network shared folders) and HTTP. The Vista laptop connects to and browses sites on the Internet without any problems. It can log into the NAS via SMB and list the shared folders (so there is nothing wrong with the log-in credentials), but when it tries to open any of the folders Explorer just hangs with the spinning cursor for several minutes and then says "\192.168.1.64\shared\Photos is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network name is no longer available." It can ping the NAS successfully. If I try to open the NAS drive's web interface, the browser just hangs. This is the same with IE, Firefox and Chrome. (There is no proxy.) I can log into the NAS drive with FTP and navigate directories, but when I try to list the contents of a directory with more than a handful of entries, the ftp client hangs. I set up a website on the MacBook. The Vista laptop was able to load some of the pages, but loading any of the images was very hit and miss. Images embedded in HTML pages never worked no matter how many times I reloaded the page, but when I linked directly to the image it did load (though several attempts were sometimes needed). I tried all of this with the Windows Firewall turned off, and with AVG turned off. That made no difference. I'd really appreciate any suggestions anyone can make. The fact that the Vista laptop has trouble with HTTP and FTP as well as SMB connections suggests to me that this is a problem at the TCP level or below. But don't forget it accesses sites outside the LAN with no problems.

• Rsyslog is not working properly, it does not log anything

  - by Victor Henriquez

  I'm running a Debian server and a couple of days ago my rsyslog started to behave very weird, the daemon is running but it doesn't seem to do anything.

• Mysql: Perform of NOT EXISTS. Is it possible to improve permofance?

  - by petRUShka

  I have two tables posts and comments. Table comments have post_id attribute. I need to get all posts with type "open", for which there are no comments with type "good" and created date MAY 1. Is it optimal to use such SQL-query: SELECT posts.* FROM posts WHERE NOT EXISTS ( SELECT comments.id FROM comments WHERE comments.post_id = posts.id AND comments.comment_type = 'good' AND comments.created_at BETWEEN '2010-05-01 00:00:00' AND '2010-05-01 23:59:59') I'm not sure that NOT EXISTS is perfect construction in this situation.

• libvirt upgrade caused vms to not see drives (boot media not found)

  - by bias

  I upgraded to Ubuntu 12.04.1 and now libvirt (via open nebula) successfully runs vms but they aren't finding the 2 drives (specifically, the boot drive). One is "hd" the other is "cdrom". The machine boots but fails and displays something like "boot media not found hd" (this was in a vnc terminal and I didn't copy the output anywhere so that's not the verbatim message). I tried constructing a new disk using the new version of qemu (via vmbuilder) and this new machine has the same problem as the old machine. In case it matters (I can't see why it would) I'm using open nebula to manage the machines. There's nothing relevant in any of the logs: syslog, libvirtd, oned. Which is to say nothing interesting/anomalous is reported when the machine is brought up.

• How do I correctly use two Not Exists statements in a where clause using Access SQL VBA?

  - by Bryan

  I have 3 Tables: NotHeard,analyzed,analyzed2. In each of these tables I have two columns named UnitID and Address. What I'm trying to do right now is to select all of the records for the columns UnitID and Address from NotHeard that don't appear in either analyzed or analyzed2. The SQL statement I created was as follows: SELECT UnitID, Address INTO [NotHeardByEither] FROM [NotHeard] Where NOT EXISTS( Select analyzed.UnitID FROM analyzed WHERE [NotHeard].UnitID = analyzed.UnitID) or NOT EXISTS( Select analyzed2.UnitID FROM analyzed2 WHERE [NotHeard].UnitID = analyzed2.UnitID) Group BY UnitID, Address I thought this would work since I've used the single NOT EXISTS subquery line and it has worked just fine for me in the past. The above query however returns the same data that is in the NotHeard table whereas if I take out the or NOT EXISTS part it works correctly. Any ideas as to what I'm doing wrong or how to do what I'm wanting to do?

• Sendmail not working from local PHP when headers not specified

  - by Dan

  Hi. I'm having trouble getting my local XAMPP server to send emails via my remote SMTP server. In PHP, if I put: $headers = "From: [email protected]\r\n"; mail('[email protected]', 'test', '', $headers); Then this works. However, if I don't specify the header, ie.: mail('[email protected]', 'test', ''); Then this fails. The sendmail.log file says: smtpstatus=554 smtpmsg='554 Message refused.' errormsg='the server did not accept the mail' exitcode=EX_UNAVAILABLE I've tried changing my sendmail command in my php.ini to: sendmail_path = "C:/xampp/sendmail/sendmail.exe -t -f [email protected]" but this doesn't work either. Thanks for any help with this, Dan. ps. this is on windows.

• USR9108 not connecting to DSL service/not detecting carrier

  - by Salman A

  As suggested in this answer I've hooked up the phone cable to the USR9108 router. I've entered the information provided by the ISP (VPI/VCI, Username, Password etc) in the ADSL configuration section but the router does not connect to DSL service. The ASDL diagnostics fail in the first step stating that no signal was found. The same phone line when connected to ZyXEL P-660R-T1 v2 modem works successfully. Can anyone tell me how to trouble shoot this issue? Does it have something to do with 2 wire and 4 wire telephone line? PS: whats the difference between ASDL and DSL?

• UDP packets to IP addresses other than specific ones not arriving and not shown in Wireshark

  - by Max

  I'm writing a service using UDP, but I can't manage to reply to the client. When sending to the client via the DHCP-assigned IP (192.168.1.143) Wireshark shows no sent packets. The server receives and Wireshark shows any packet sent by the client (broadcasted). If I send to a random, unassigned IP Wireshark doesn't show it. I thought the NIC would happily send it, since there is a router in the way - shouldn't Wireshark show it, even though it cannot possibly be received by a remote endpoint? If I send to either the router IP or another (specific, there is only one other) computer, the packet is shown in Wireshark. I am running Windows 7, the firewall is turned off using the control panel. Does the fact that wireshark doesn't show these packets mean that they aren't sent? What reason could there be for showing packets to one IP, but not another, on the same subnet?

• Can't install Ubuntu 12 into VirtualBox (USB not recognized, ISO would not boot)

  - by wvxvw

  I'm trying out VirtualBox 4.18 and wanted to install Ubuntu 12 as a test. After installing VirtualBox (on Debian squeeze/sid), creating a virtual machine for Ubuntu and pointing it in Settings Storage IDE Controllers to the ISO with the proper version of Ubuntu, checked the "Live CD" option. Tried to define the IDE as master / slave, primary / secondary - all to no effect, and trying to boot this system, I'm getting to the screen which says: FATAL: could not read from the boot medium! System halted I've copied the same ISO to the USB stick, and I can boot from the USB (outside VirtualBox). I've looked at couple of tutorials / walk-through, there's nothing I can see that I would've done wrong. So, how would I configure it to boot from the desired ISO? Below is the snapshot with the current settings (sorry, I don't know how to get them as text).

• emacs does not open a file from argument and syntax highlight does not work

  - by Jus

  In my latest ubuntu box, When I type for example emacs ~/.bashrc, Emacs will start but not open .bashrc. This is true for any file I pass in. I've used Emacs for several years, and have never experienced this problem before. I added (global-font-lock-mode 1);; to my .emacs file, and Emacs does recognize it, for example. "(C++/; Abbrev)", but it won't do syntax highlighting. If you can solve any of these problems, it will be very appreciated.

• LEMP Stack on Ubuntu Server 13.04 not parsing PHP Switch Statement Properly

  - by schester

  On my Ubuntu 12.04 Server LTS on nginx 1.1.19, the following PHP code works properly: switch($_SESSION['user']['permissions']) { case 9: echo "Super Admin Privileges"; break; case 0: echo "Operator Privileges"; break; case 1: echo "Line Leader Privileges"; break; case 2: echo "Supervisor Privileges"; break; case 3: echo "Engineer Privileges"; break; case 4: echo "Manager Privileges"; break; case 5: echo "Administrator Privileges"; break; default: echo "Operator Privileges"; } However, I have a backup server running Ubuntu Server 13.04 on nginx 1.4.1 which has the exact same copy of the script (synced) but instead of breaking on the break; command, it echos the whole php script. The output on the 12.04 Box is similar to this: You are logged in with Super Admin Privileges But on the 13.04 Box, the output is like this: You are logged in logged in with Super Admin Privileges"; break; case 0: echo "Operator Privileges"; break; case 1: echo "Line Leader Privileges"; break; case 2: echo "Supervisor Privileges"; break; case 3: echo "Engineer Privileges"; break; case 4: echo "Manager Privileges"; break; case 5: echo "Administrator Privileges"; break; default: echo "Operator Privileges"; } ?> I have also tried changing the script from switch statement to if statements but same results. Any idea what is wrong?

• DB Schema for ACL involving 3 subdomains

  - by blacktie24

  Hi, I am trying to design a database schema for a web app which has 3 subdomains: a) internal employees b) clients c) contractors.

• MySQL Database Query Problem

  - by moustafa

  I need your help!!!. I need to query a table in my database that has record of goods sold. I want the query to detect a particular product and also calculate the quantity sold. The product are 300 now, but it would increase in the future. Below is a sample of my DB Table #---------------------------- # Table structure for litorder #---------------------------- CREATE TABLE `litorder` ( `id` int(10) NOT NULL auto_increment, `name` varchar(50) NOT NULL default '', `address` varchar(50) NOT NULL default '', `xdate` date NOT NULL default '0000-00-00', `ref` varchar(20) NOT NULL default '', `code1` varchar(50) NOT NULL default '', `code2` varchar(50) NOT NULL default '', `code3` varchar(50) NOT NULL default '', `code4` varchar(50) NOT NULL default '', `code5` varchar(50) NOT NULL default '', `code6` varchar(50) NOT NULL default '', `code7` varchar(50) NOT NULL default '', `code8` varchar(50) NOT NULL default '', `code9` varchar(50) NOT NULL default '', `code10` varchar(50) NOT NULL default '', `code11` varchar(50) character set latin1 collate latin1_bin NOT NULL default '', `code12` varchar(50) NOT NULL default '', `code13` varchar(50) NOT NULL default '', `code14` varchar(50) NOT NULL default '', `code15` varchar(50) NOT NULL default '', `product1` varchar(100) NOT NULL default '0', `product2` varchar(100) NOT NULL default '0', `product3` varchar(100) NOT NULL default '0', `product4` varchar(100) NOT NULL default '0', `product5` varchar(100) NOT NULL default '0', `product6` varchar(100) NOT NULL default '0', `product7` varchar(100) NOT NULL default '0', `product8` varchar(100) NOT NULL default '0', `product9` varchar(100) NOT NULL default '0', `product10` varchar(100) NOT NULL default '0', `product11` varchar(100) NOT NULL default '0', `product12` varchar(100) NOT NULL default '0', `product13` varchar(100) NOT NULL default '0', `product14` varchar(100) NOT NULL default '0', `product15` varchar(100) NOT NULL default '0', `price1` int(10) NOT NULL default '0', `price2` int(10) NOT NULL default '0', `price3` int(10) NOT NULL default '0', `price4` int(10) NOT NULL default '0', `price5` int(10) NOT NULL default '0', `price6` int(10) NOT NULL default '0', `price7` int(10) NOT NULL default '0', `price8` int(10) NOT NULL default '0', `price9` int(10) NOT NULL default '0', `price10` int(10) NOT NULL default '0', `price11` int(10) NOT NULL default '0', `price12` int(10) NOT NULL default '0', `price13` int(10) NOT NULL default '0', `price14` int(10) NOT NULL default '0', `price15` int(10) NOT NULL default '0', `quantity1` int(10) NOT NULL default '0', `quantity2` int(10) NOT NULL default '0', `quantity3` int(10) NOT NULL default '0', `quantity4` int(10) NOT NULL default '0', `quantity5` int(10) NOT NULL default '0', `quantity6` int(10) NOT NULL default '0', `quantity7` int(10) NOT NULL default '0', `quantity8` int(10) NOT NULL default '0', `quantity9` int(10) NOT NULL default '0', `quantity10` int(10) NOT NULL default '0', `quantity11` int(10) NOT NULL default '0', `quantity12` int(10) NOT NULL default '0', `quantity13` int(10) NOT NULL default '0', `quantity14` int(10) NOT NULL default '0', `quantity15` int(10) NOT NULL default '0', `amount1` int(10) NOT NULL default '0', `amount2` int(10) NOT NULL default '0', `amount3` int(10) NOT NULL default '0', `amount4` int(10) NOT NULL default '0', `amount5` int(10) NOT NULL default '0', `amount6` int(10) NOT NULL default '0', `amount7` int(10) NOT NULL default '0', `amount8` int(10) NOT NULL default '0', `amount9` int(10) NOT NULL default '0', `amount10` int(10) NOT NULL default '0', `amount11` int(10) NOT NULL default '0', `amount12` int(10) NOT NULL default '0', `amount13` int(10) NOT NULL default '0', `amount14` int(10) NOT NULL default '0', `amount15` int(10) NOT NULL default '0', `totalNaira` double(20,0) NOT NULL default '0', `totalDollar` int(20) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='InnoDB free: 4096 kB;

• STL operator= behavior change with Visual Studio 2010?

  - by augnob

  Hi, I am attempting to compile QtScriptGenerator (gitorious) with Visual Studio 2010 (C++) and have run into a compile error. In searching for a solution, I have seen occasional references to compile breakages introduced since VS2008 due to changes in VS2010's implementation of STL and/or c++0x conformance changes. Any ideas what is happening below, or how I could go about fixing it? If the offending code appeared to be QtScriptGenerator's, I think I would have an easier time fixing it.. but it appears to me that the offending code may be in VS2010's STL implementation and I may be required to create a workaround? PS. I am pretty unfamiliar with templates and STL. I have a background in embedded and console projects where such things have until recently often been avoided to reduce memory consumption and cross-compiler risks.

• How does + operator behaves differently with numbers and strings in Java?

  - by Abhishek Jain

  Java does not have concept of operator overloading. Still + operator behaves as addition operator with numbers and concatenate operator with strings. This is similar to the operator overloading behavior. Please suggest.

• vector does not erase content correctly (infite amount run of copy asignment operator untill crash [BEX])?

  - by Gam Erix

  Well my problem is that after I want to "unload" loaded DLL's the copy assignmnent operator is called an unlimited amount of times until crash. The code from which I remove the vector data looks like this: void UnloadPlugins() { dbg(("[DBG]UnloadPlugins()")); for(std::vector<DLLInfo>::iterator it = plugins.begin(); it != plugins.end(); ++it) { plugins.erase(it); } dbg(("[DBG]UnloadPlugins()::Done")); } however "[DBG]UnloadPlugins()::Done" gets never printed. this is my copy assignmnent operator: // 2. copy assignment operator DLLInfo& operator=(const DLLInfo& that) { dbg(("[DBG]Start-DLLInfo& operator=(const DLLInfo& that)")); Instance = that.Instance;//hinstance dbg(("[DBG]DLLInfo 1")); //Identifier.assign(that.Identifier);//string dbg(("[DBG]DLLInfo 2")); IsAMX = that.IsAMX;//integer dbg(("[DBG]DLLInfo 3")); dwSupportFlags = that.dwSupportFlags;//integer dbg(("[DBG]DLLInfo 4")); Load = that.Load;//integer dbg(("[DBG]DLLInfo 5")); Unload = that.Unload;//integer dbg(("[DBG]DLLInfo 6")); Supports = that.Supports;//integer dbg(("[DBG]DLLInfo 7")); ProcessTick = that.ProcessTick;//integer dbg(("[DBG]DLLInfo 8")); AmxLoad = that.AmxLoad;//integer dbg(("[DBG]DLLInfo 9")); AmxUnload = that.AmxUnload;//integer dbg(("[DBG]DLLInfo 10")); UseDestructor = that.UseDestructor;//bool dbg(("[DBG]DLLInfo 11")); KeyboardHit = that.KeyboardHit;//integer dbg(("[DBG]End-DLLInfo& operator=(const DLLInfo& that)")); return *this; } So the log looks like: [17:50:50] [DBG]UnloadPlugins() [17:50:50] [DBG]~DLLInfo [17:50:50] [DBG]~DLLInfo::if(this->UseDestructor) passed [17:50:50] [DBG]~DLLInfo::if(this->UseDestructor)::if(this->Unload != NULL && this->IsAMX) passed [17:50:50] [DBG]~DLLInfo::end [17:50:50] [DBG]Start-DLLInfo& operator=(const DLLInfo& that) [17:50:50] [DBG]DLLInfo 1 [17:50:50] [DBG]DLLInfo 2 [17:50:50] [DBG]DLLInfo 3 [17:50:50] [DBG]DLLInfo 4 [17:50:50] [DBG]DLLInfo 5 [17:50:50] [DBG]DLLInfo 6 [17:50:50] [DBG]DLLInfo 7 [17:50:50] [DBG]DLLInfo 8 [17:50:50] [DBG]DLLInfo 9 [17:50:50] [DBG]DLLInfo 10 [17:50:50] [DBG]DLLInfo 11 [17:50:50] [DBG]End-DLLInfo& operator=(const DLLInfo& that) [17:50:50] [DBG]Start-DLLInfo& operator=(const DLLInfo& that) ...

• Postfix: LDAP not working (warning: dict_ldap_lookup: Search base not found: 32: No such object)

  - by Heinzi

  I set up LDAP access with postfix. ldapsearch -D "cn=postfix,ou=users,ou=system,[domain]" -w postfix -b "ou=users,ou=people,[domain]" -s sub "(&(objectclass=inetOrgPerson)(mail=[mailaddr]))" delivers the correct entry. The LDAP config file looks like root@server2:/etc/postfix/ldap# cat mailbox_maps.cf server_host = localhost search_base = ou=users,ou=people,[domain] scope = sub bind = yes bind_dn = cn=postfix,ou=users,ou=system,[domain] bind_pw = postfix query_filter = (&(objectclass=inetOrgPerson)(mail=%s)) result_attribute = uid debug_level = 2 The bind_dn and bind_pw should be the same as I used above with ldapsearch. Nevertheless, calling postmap doesn't work: root@server2:/etc/postfix/ldap# postmap -q [mailaddr] ldap:/etc/postfix/ldap/mailbox_maps.cf postmap: warning: dict_ldap_lookup: /etc/postfix/ldap/mailbox_maps.cf: Search base 'ou=users,ou=people,[domain]' not found: 32: No such object If I change LDAP configuration, so that anonymous users have complete access to LDAP olcAccess: {-1}to * by * read then it works: root@server2:/etc/postfix/ldap# postmap -q [mailaddr] ldap:/etc/postfix/ldap/mailbox_maps.cf [user-id] But when I restrict this access to the postfix user: olcAccess: {-1}to * by dn="cn=postfix,ou=users,ou=system,[domain]" read by * break it doesn't work but produces the error printed above (although ldapsearch works, only postmap doesn't). Why doesn't it work when binding with a postfix DN? I think I set up the LDAP ACL for the postfix user correctly, as the ldapsearch command should prove. What can be the reason for this behaviour?

• Samba server NETBIOS name not resolving, WINS support not working

  - by Eric

  When I try to connect to my CentOS 6.2 x86_64 server's samba shares using address \\REPO (NETBIOS name of REPO), it times out and shows an error; if I do so directly via IP, it works fine. Furthermore, my server does not work correctly as a WINS server despite my samba settings being correct for it (see below for details). If I stop the iptables service, things work properly. I'm using this page as a reference for which ports to use: http://www.samba.org/samba/docs/server_security.html Specifically: UDP/137 - used by nmbd UDP/138 - used by nmbd TCP/139 - used by smbd TCP/445 - used by smbd I really really really want to keep the secure iptables design I have below but just fix this particular problem.
