• Open source tomcat log viewer

  - by Ari

  I'm managing several tomcat instances (aprox 30-35) and looking for some console to centralize the logs. I tried php-syslog-ng before (no with tomcat), and found it useful. I would like that these software would have some of these features: -Syntax highlight according to the severity of the exceptions. -Tree view for stack traces and nested exceptions. Bonus point: -Alarm when certain pattern is matched.

• setting up synergy (multi-computer shared input devices) new to mac

  - by pedalpete

  I've just gotten a mac and the first thing I'm trying to do in setting it up for dev is to set-up synergy. I've run into countless issues, and am making progress, but that 'mac's just work' theory is getting tired really fast. I'd prefer running the mac as the server, as it's a desktop. why use my pc(laptop) as the server. So i downloaded synergy, and tried to edit the 'synergy.conf' file. First with textmate, then with apple script. Neither of these applications will open the file. Even after changing textmate to use plain text format and switching off a few other things to make it into a plain text editor. No good. Uh, isn't that what these script/text editors are for? Then I found SyneryKM which is a package to run synergy on osx. Took LOTS of fiddling, but I think I finally kinda got it figured out. I've got my pc & mac both running synergy. However, my pc will only connect to synergy using the ip address. No problem, however, my mac won't connect to itself as a synergy server using the IP address. If I use the ip address as a screen in the 'server configuration file', i get a 'Error: unknown screen name mymac'. I know this shouldn't be super complicated, and possibly not the place to find answers about synergy, but I couldn't find a better place, and there has been some talk of synergy here. Any chance somebody can help with this?

• How to use cyg-wrapper to fork a new tab in win32 gvim

  - by Peter Nore

  I would like to set up an alias in my cygwin .bashrc that translates pathnames unix-to-dos and passes them to windows gvim in a new tab of an existing instance. I am trying to use Luc Hermitte's cyg-wrapper script for running native win32 applications from Cygwin as per this vim tip. Luc's example of how to use his script is: alias vi= 'cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=-c,--cmd,-T,-t,--servername,--remote-send,--remote-expr' I do not understand this example because most of these vim parameters (-c,--cmd,--servername,--remote-send,--remote-expr, etc) require more information, and I have not found any example of how to supply the additional information to cyg-wrapper.sh. For example, calling C:/Progra~1/Edition/vim/vim63/gvim.exe --servername=GVIM --remote-tab-silent file1 & will open file1 in a new tab of existing (or non existing) instance GVIM, but calling gvim --servername accomplishes nothing on its own. Unfortunately, though, the corresponding cyg-wrapper phrase does not work: cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 file1 If ran twice, this actually opens up two instances of gvim; it is as if the servername 'GVIM' is being stripped and ignored. How do you supply a servername to gvim --servername or a .vimrc to gvim -u using cyg-wrapper.sh? Furthermore, why is it that programs must be passed to cyg-wrapper.sh in the relatively obscure "mixed form?" For example, if I try cyg-wrapper.sh "/cygdrive/c/path/to/GVimPortable.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 I get "Invalid switch - "/cygdrive"."

• How to permanently "renice" a process on Mac OS X (or iOS, etc)?

  - by mralexgray

  I use a nice (free) process manager called ATMonitor for Mac OS X that has a lot of cool hidden features... one of which is being able to click on a running process.. and set the "renice" from +20 (less priority) to -20 (highest priority). The best part.... it sticks between restarts... SO you want XYZ to get full attention all the time.. you set it once and it's done... I want to do the same thing (renice a process) on an iPad running a particular daemon.. and I don't know how to set a renice permanently. I can do it once, and it works fine... But the setting is lost on a reboot. I read somewhere.. Now, as for permanently resetting the priority of a process, this can't be done directly. You can fake it, however, with a shell script that starts the app and then immediately renice's it. Give that script a ".command" extension and it will be double-clickable in the GUI. Not very elegant, but it gets the job done. But as it says.. not very elegant, and I dont think this is how ATMonitor does it.... I found this thread.... http://superuser.com and they gave a way to do it as a launch argument, but no apparent way to save it as a persistent value... for instance - if the program wasn't going to be started by launchd... How do I set a permanent renice level, per executable binary, independent of it's PID, when, how or why it was launched?

• Process runs slower as a scheduled task than it does interactively

  - by Charlie

  I have a scheduled task which is very CPU- and IO-intensive, and takes about four hours to run (building source code, if you're curious). The task is a Powershell script which spawns various sub-processes to do its work. When I run the same process interactively from a Powershell prompt, as the same user account, it runs in about two and a half hours. The task is running on Windows Server 2008 R2. What I want to know is why it takes so much longer to run as a scheduled task - more than an hour longer. One thing I noticed is that the task scheduler runs at Below-Normal priority, so when my task starts, it inherits the same lowered priority. However, I've updated the script to set the Powershell process priority back to Normal, and it still takes just as long. Anybody have an idea what could be different between the two scenarios? I've ruled out differences in processor and IO load - this task is the only thing the system is used for, so there's nothing else running that could be competing for resources.

• Weblogic 12 and the CLI

  - by Rig

  I am working with WebLogic on Fedora 19 and am attempting to use the CLI tools to no avail. It appears these were deprecated as far back as WebLogic 9 however I was assured they are still there and still functional. As it stands I have a need to use them if they are in fact functional. What appears to the case is that the weblogic jar file is not being loaded correctly to the classpath by this script after trying to manually add it to the classpath as it fails when trying to add those jars via java -classpath <path>. I've spent a lot of time so far trying to get this sorted out but I'm wondering what I may be missing here. My Java runtime is version 7, Fedora is 19, and WebLogic is 12.1. When I run env after running the provided set environment script it appears to have no impact from what I can see. (I'll add that later when I get back to that machine). I'm mostly a Windows developer so some of this is a topic I'm not well versed in. [foo@localhost bin]$ ./setDomainEnv.sh [foo@localhost bin]$ java weblogic.Admin -url t3://localhost:7001 -username <username> -password <password> HELP Error: Could not find or load main class weblogic.Admin [foo@localhost bin]$ ls -ltar total 72 drwxr-x--- 2 foo foo 4096 Jun 2 07:36 service_migration drwxr-x--- 2 foo foo 4096 Jun 2 07:36 server_migration drwxr-x--- 2 foo foo 4096 Jun 2 07:36 nodemanager -rwxr-x--- 1 foo foo 1267 Jun 2 07:36 setStartupEnv.sh -rwxr-x--- 1 foo foo 1105 Jun 2 07:36 startNodeManager.sh -rwxr-x--- 1 foo foo 5765 Jun 2 07:36 startWebLogic.sh -rwxr-x--- 1 foo foo 2001 Jun 2 07:36 stopWebLogic.sh -rwxr-x--- 1 foo foo 3170 Jun 2 07:36 startManagedWebLogic.sh -rwxr-x--- 1 foo foo 2776 Jun 2 07:36 stopManagedWebLogic.sh -rwxrwxrwx 1 foo foo 14136 Jun 2 07:36 setDomainEnv.sh -rwxr-x--- 1 foo foo 2060 Jun 2 07:36 startComponent.sh drwxr-x--- 5 foo foo 4096 Jun 2 07:36 . -rwxr-x--- 1 foo foo 1726 Jun 2 07:36 stopComponent.sh drwxr-x--- 12 foo foo 4096 Jun 2 07:45 ..

• How to run some commands after booting from ArchLinux disk? Or how to change some settings in .iso before booting?

  - by Alexander Ovchinnikov

  How to install Arch Linux with traditional installer with only ssh-access to server? There is nice guide: https://wiki.archlinux.org/index.php/Install_from_SSH I try test this on my home vps: Start VPS with any linux bootable cd and login to remote server (vps) wget http://mirrors.kernel.org/archlinux/iso/latest/archlinux-2010.05-netinstall-x86_64.iso dd if=archlinux-2010.05-netinstall-x86_64.iso of=/dev/sda reboot ... I see, it works but without ssh connection... I need make script, which will send this commands after reboot: aif -p partial-configure-network (and write some information about my server ip etc.) /etc/rc.d/sshd start (need to start sshd) echo "sshd: ALL" /etc/hosts.allow (to allow me login to server, by default deny all) passwd (by default its empty, can't login via ssh with empty password) Can I edit .iso or may be /dev/sda? May be I need write script, which will start after system boot and do this things or may be I can set this settings by default and system will start with correct settings (i think its possible at least in 2. and 3.). Thank you!

• How to register an agent with launchd

  - by Konrad Rudolph

  I’m unable to schedule a periodic launch with launchctl/launchd on OS X (Leopard). Basically, I’m unable to find a step-by-step list of instructions on the web and the intuitive approach doesn’t work. The sync.plist file: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>net.madrat.utils.sync</string> <key>Program</key> <string>rsync</string> <key>ProgramArguments</key> <array> <string>-ar</string> <string>/path/to/folder/</string> <string>/path/to/backup/</string> </array> <key>StartInterval</key> <integer>7200</integer> </dict> </plist> I’ve put this script inside the path ~/Library/LaunchAgents. Next, I’ve registered the script using launchctl load ~/Library/LaunchAgents/sync.plist Finally, to test that it works, I started the job: launchctl start net.madrat.utils.sync – Nothing happened. Manually executing the rsync command in the terminal yields the expected result. I’m fairly sure that the job was registered correctly because if I try to start a non-existing job, I get an error message (which I didn’t get in the above command). What did I do wrong?

• python mysqldb - mysql server gone away - can't reconnect

  - by david.barkhuizen

  Hi Folks, When attempting to import a bunch of data into mysql tables using python and mysqldb, I run into the following error '2006 - mySQL Server has gone away', and then I am unable to reconnect again within the script. I am iniitially re-using a connection object across transactions ( delineated by conn.commit() ), then when I first encounter this exception, if I create a new connection by calling MySQLdb.connect(), this new connection also fails with the same exception. This error does not occur immediately, I can pump a fair amount of data into the db, but then faithfully occurs after I have inserted a couple thousand records, so roughly once the db has committed a certain transaction volume, it always falls over like this. If I rerun the script, WITHOUT restarting the db server. then it resumes where it left off, pumps in some data, then falls over again. Before recommendations to change time-out timings, does anyone know why I am not able to establish a new connection after the initial failure ? - Even if I try a couple of times waiting a couple of seconds between each. (btw, I'm running Windows 7, mysql server 5.1.48, mysqldb 1.2.3.gamma.1, python 2.6)

• memcached append() php ubuntu - bad protocol

  - by awongh

  I am running ubuntu gutsy(7.1) , php5 and I am trying to get memcached running locally. I installed everything as per the docs: memcached daemon, php PECL extension, libevent, etc. But now I can only run half of the example script for memcached append(): <?php $m = new Memcached(); $m->addServer('localhost', 11211); $m->setOption(Memcached::OPT_COMPRESSION, false); $m->set('foo', 'abc'); $m->append('foo', 'def'); var_dump($m->get('foo')); ?> the script terminates @ append() with an RES_BAD_PROTOCOL error message. It still runs the get(). I don't know why memcached would otherwise be working fine (connect, set, get - with the correct value of 'abc') and not work for append. it also doesnt work with prepend. I believe I have the setup correct, but I am not sure. Maybe there are compatibility problems between the versions of the dependecies? thanks much

• Extracting data from Visual FoxPro databases

  I just got some 20Gb of data in a Visual FoxPro database with a custom frontend probably written in the same framework, and need to extract that data in any well-known format. I don't know anything about VFP in particular, but as it is SQL, there should be a way of opening an SQL console, or maybe an vfpdump utility. How can I do that? Everything I have now are a bunch of obscure binary files and a frontend executable.

• wget not working with domain on local machine

  - by user568829

  Basically - I have some PHP scripts that need to be run as cron jobs. Lets say the script needing to be run is: http://admin.somedomain.com/cron_jobs/get_stats If I run the script from the local machine it gives me a 404 Not Found error. So I entered the following into /etc/hosts XX.XX.XX.45 admin.somedomain.com Now wget works fine from the local machine to that domain. However when I restart Apache that domain no longer works. Here is the config for that site in /etc/apache2/sites-available NameVirtualHost XX.XX.XX.45:80 <VirtualHost XX.XX.XX.45:80> ServerName admin.somedomain.com DocumentRoot /var/www/admin.somedomain.com/ <Directory "/var/www/admin.somedomain.com"> allowoverride all Options Indexes order deny,allow allow from all </Directory> ErrorLog /var/log/apache2/admin.somedomain.com-error_log CustomLog /var/log/apache2/admin.somedomain.com-access_log combined </VirtualHost> It just goes to the default site config showing "It Works". If I take out that setting in /etc/hosts and restart apache the website at that domain works fine again. Can anyone point me in the right direction here? Thanks

• Force Windows Local Subnet Traffic through a Gateway

  - by Beerey

  Hi all, We are attempting to route all traffic from a certain machine to a gateway. This works ok for traffic destined for subnets outside of the machine's subnet. However, traffic to machines in the same subnet as the source machine goes through an On-Link gateway in Windows. This means that the default gateway is ignored, and traffic in a subnet (for example, 192.168.50.10 - 192.168.50.11) flows. Destination Netmask Gateway Interface Metric 192.168.50.0 255.255.255.0 On-link 192.168.50.214 276 This route can be deleted from Windows, but when the machine is rebooted it always comes back. Adding a persistant static route to the gateway with a lower metric doesn't work, since it will still try the On-Link gateway after the persistant route fails. Adding each machine in a VLAN isn't an option due to the setup we have Adding a startup script to delete the gateway isn't a great option either, since users will have full admin access to the machine and might disable the script. We cannot transperantly intercept all network traffic on the subnet using Gratuitous ARPs or transparent proxying, since there are other machines on the subnet which use a different gateway The only way we have gotten it to work is by adding a persistant route to the gateway for the subnet traffic, and deleting the On-link route on reboot. The question is then. Is there a way to permanently remove this On-link route If not, is there a way to otherwise force even local subnet traffic to go through a gateway?

• Monitor Exchange Email Address and run scripts

  - by WernerCD

  Okay... Not sure how "out there" this thought is... Right now to send a pager message (aka text message), a user logs into our AS400... logs into the program... enters user name and message and hit's F10 to send. With a little looking, it seems that you can run remote commands to the AS400 via FTP. So I'm working on building a script (batch or otherwise) that, given two parameters (user, message), will FTP into the AS400 and run a remote command: c:\>ftp server user: admin password: ***** ftp> quote rcmd SNDPGRMSG TOPGR(JDOE) MSG('This is a Test') ftp> quit So... what I want to do is setup an email account on our Exchange server Monitor the account for incoming mail upon receipt of incoming mail, parse it... say for example subject is defined as "Recipient" and email text is defined as "Pager message" run a batch that uses the above mentioned TOPGR and MSG as parameters... via FTP to the AS400 mark email as "read" The main thing I'm not sure about is monitoring an exchange account and running a script on incoming emails. I'm sure what I want to do is possible... but where would I start? EDIT: Clarification The main reasons for using this four part system are logging (messages sent via this are logged and reported by the AS400 program) and the existing scheduler for redirecting pages (For example, the weekly on-call person = TOPGR(oncall) gets updated by the AS400 program). I'm also trying to remove duplicate work. If I can get this setup working, I can redirect pages from OTHER systems into this one. I then don't have to update 2, soon to be 3, systems with current phone numbers, carriers, on-call schedules, etc. System #2 and #3 can just "email" [email protected].

• How to perform SCP as a Sudo user

  - by Ramesh.T

  What is the best way of doing SCP from one box to the other as a sudo user. There are two servers Server A 10.152.2.10 /home/oracle/export/files.txt User : deploy Server B 10.152.2.11 /home/oracle/import/ User : deploy Sudo user : /usr/local/bin/tester all i want is to copy files from server A to Server B as a sudo user... In order to do this, first i normally login as deploy user on the target server and then switch as a sudo user without password. after that SCP to copy file, this is the normal way i perform this activity... In order to auotmate i have written script #!/bin/sh ssh deploy@lnx120 sudo /usr/local/bin/tester "./tester/deploy.sh" I have generated the private key for deploy user, so it allows me to login as deploy user without password. afterthar the sudo command is executed it will switch the user to tester... after that nothing happens.. i mean the script is not getting executed ... is there any way to accomplish this in a different way...

• How does a vsftpd server work and how to configure it?

  - by ysap

  I was asked to configure a FTP server, based on the vsftpd package. The server is running on a remote machine to which I have a superuser privilege access. Being unfamiliar with the mechanics of FTP servers, I tried to figure out how user ftp accounts are configured. The previous maintainer used a shell script, which works on a list that we maintain to track users accounts and passwords, to configure the ftp accounts. From reading the script, I see that he generates a list of usernames and passwords, and actually creates a user account on the Linux machine. This means that for each user that we configure in the list, a new user account is being added by the adduser command: adduser --home /home/ftp --no-create-home $user (but w/o a private /home/username directory - using the /home/ftp instaed). Each of these users can log into his account using the ssh command. This fact seems a little strange to me, as I'd think that the ftp account should be decoupled from the Ubuntu user accounts. As another side effect, when a user connects using a web browser, he is connected to the /home/ftp directory. However, he can then use "Up to a higher level directory" link to go up and effectively have access to all of our system. So, the questions are: Is this really how the FTP server supposed to work in terms of configuring ftp accounts? If not, how do I configure the vsftpd server in a way that I have only the superuser Ubuntu account on that machine and all ftp account are... just FTP user accounts? Additionally, these ftp account should be configured in terms of how and what they are allowed to access.

I'm using CentOS 6.2 as both host and guest, not using libvirt, just running qemu-kvm directly as follows: /usr/libexec/qemu-kvm \ -drive file=/data2/vm/rb-dev2-www1-vm.img,index=0,media=disk,cache=none,if=virtio \ -boot order=c \ -m 2G \ -smp cores=1,threads=2 \ -vga std \ -name rb-dev2-www1-vm \ -vnc :84,password \ -net nic,vlan=0,macaddr=52:54:20:00:00:54,model=virtio \ -net tap,vlan=0,ifname=tap84,script=/etc/qemu-ifup \ -monitor unix:/var/run/vm/rb-dev2-www1-vm.mon,server,nowait \ -rtc base=utc \ -device piix3-usb-uhci \ -device usb-tablet /etc/qemu-ifup (used by the above command) is a very simple script, containing the following: #!/bin/sh sudo /sbin/ifconfig $1 0.0.0.0 promisc up sudo /usr/sbin/brctl addif br0 $1 sleep 2 And here's the info on br0 and other interfaces: avl-host3 14# brctl show bridge name bridge id STP enabled interfaces br0 8000.180373f5521a no bond0 tap84 virbr0 8000.525400858961 yes virbr0-nic avl-host3 15# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000 link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff 3: em2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000 link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff 4: em3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 18:03:73:f5:52:1e brd ff:ff:ff:ff:ff:ff 5: em4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 18:03:73:f5:52:20 brd ff:ff:ff:ff:ff:ff 6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff inet6 fe80::1a03:73ff:fef5:521a/64 scope link valid_lft forever preferred_lft forever 7: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 18:03:73:f5:52:1a brd ff:ff:ff:ff:ff:ff inet 172.16.1.46/24 brd 172.16.1.255 scope global br0 inet6 fe80::1a03:73ff:fef5:521a/64 scope link valid_lft forever preferred_lft forever 8: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 52:54:00:85:89:61 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 9: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500 link/ether 52:54:00:85:89:61 brd ff:ff:ff:ff:ff:ff 12: tap84: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500 link/ether ba:e8:9b:2a:ff:48 brd ff:ff:ff:ff:ff:ff inet6 fe80::b8e8:9bff:fe2a:ff48/64 scope link valid_lft forever preferred_lft forever bond0 is a bond of em1 and em2. virbr0 and virbr0-nic are vestigial interfaces left over from CentOS's default installation. They are unused (as far as I know). The guest runs perfectly until I run a large 'rsync', when the network will freeze after some seemingly-random time (usually under a minute). When it freezes, there is no network activity in or out of the guest. I can still connect to the guest's console via vnc, but it is unable to speak out its network interface. Any attempt to 'ping' from the guest gives a "Destination Host Unreachable" error for 3/4 packets and no reply for every fourth packet. Sometimes (perhaps two thirds of the time), I can bring the interface back to life by doing a "service network restart" from the guest's console. If this works (and if I do it before the rsync times out), the rsync will resume. Usually it will freeze again within a minute or two. If I repeat, the rsync will eventually finish, and I presume the machine goes back to waiting for another period of heavy load. Throughout the whole process, there are no console errors or relevant (that I can see) syslog messages on either guest or host machine. If the "service network restart" doesn't work the first time, trying again (and again and again) never seems to work. The command completes normally, with normal output, but the interface stays frozen. However, a soft reboot of the guest machine (without restarting qemu-kvm) always seems to bring it back. I am aware of the "lowest mac address" assignment problem, where the bridge takes on the mac address of the slave interface with the lowest mac address. This causes temporary network freezes, but is definitely not what's happening for me. My freezes are permanent until manual intervention, and you can see from the 'ip addr show' output above that the mac address being used by br0 is that of the physical ethernet. There are no other virtual machines running on the host. I've verified that each virtual machine on the subnet has its own unique mac address. I have rebuilt the guest machine several times, and I have tried this on three different host machines (identical hardware, built identically). Oddly, I do have one virtual host (the second of this series) which never seemed to have a problem. It never had its network freeze when it was running the same rsync during its build. It's particularly odd because it was the second build. The first, on a different host, did have the freezing problem, but the second did not. I assumed at the time that I had done something wrong with the first build, and that the problem was resolved. Unfortunately, the problem reappeared when I built the third VM. Also unfortunately, I can't do many tests with the working VM, as it's now in production use, and I'm hoping I can find the cause of this issue before that machine starts having problems. It's possible that I just got really lucky while running the rsync on the working machine, and that one time it didn't freeze. Of course it's possible that I somehow changed the build scripts without realizing it and re-broke something, but I can't find any such thing. In any case, I'm hoping someone has some idea what could cause this. Addendum: Preliminary tests suggest that I don't have the problem if I substitute e1000 for virtio in the first -net flag to qemu-kvm. I don't consider this a solution, but it is suitable for a stopgap. Has anyone else had (or better yet, solved) this problem with the virtio network driver?

• "Hide from exchange address lists" not working in Exchange 2007

  - by Abdullah

  Hiding a user by checking the "hide from exchange address lists" from exchange management console is not working. The user still shows up in GAL. When I ran Get-Mailbox -Identity _user_ | FL I got HiddenFromAddressListsEnabled : True So the check-box is working but the user still shows up. It's been over 3 weeks since hiding the user so it's not a time issue. This is what I have tried: Using Outlook in online mode Using OWA Regenerating GAL Un-checking then re-checking the "hide" check-box
