  • Building a Mac/PC Network in a Dorm with Network Restrictions

    - by user70340
    I have been a Windows XP user for the last few years, but I recently bought a 15'' MacBook Pro for research purposes. I would like to set up a no-hassle Mac/PC Network at home so that I can access the internet on both computers and hardware between computers (i.e. a harddrive, or a mouse/keyboard with Synergy). Unfortunately, I live in a dorm with silly network restrictions so a solution is not straightforward. In particular: The dorm has a wired and wireless network, both which provide an internet connection. The wired network provides way faster internet (download speeds of 15 MB/s vs. 2 MB/s on wireless), so I would like to somehow exploit this, at least on my PC for Bittorrent :) Multiple devices can connect to the wireless network, but cannot "see" each other on the network (so software like Synergy would not work). Only 1 MAC address can connect to the wired network at a time. Ideally I would just connect a wireless router to the wired network and then have both the Mac and the PC on that, but the 1 MAC address restriction will not allow the both computer to access the internet simultaneously. I cannot think of a way to bypass this restriction (though I'm not network savvy), so I am planning to create a private no-internet network to allow the devices to see each other and share hardware. Here are some thoughts. I would appreciate any feedback at all! If I build a private wireless network: (first choice) I will use a wireless router that is not connected to the internet. My PC and Mac will be connected to each other wirelessly. I can then connect the PC to the internet via a wired network, but then the Mac will not have internet access as its wireless card is already in use. In this case, could I stream internet access from the PC to the Mac via the wireless network? Or could I buy a USB wireless card for the Mac so that it can connect to both my private network and the dorm network? If I build a private wired network: (second choice) Then both the PC and the Mac will connect to the internet wirelessly, which means I cannot take advantage of the faster download speeds.

  • My computer's dying :(

    - by j-t-s
    Hi All I have a sweet computer and have never had any real problems with it until now. I recently formatted my computer and all was well. But now my monitor randomly flickers. The monitor will just go black for about a second or two, then it'll return back to its normal state with all the stuff still on the screen. This is getting progressively worse. Another problem that has started is my computer randomly restarts. (I've managed to prevent it from restarting by removing the check in Automatically Restart from the Startup and Recovery Dialog. But I know this doesn't solve the problem). It also completely freezes up on me. One last thing, this morning I got a big blue screen. I can't remember what it said, but if it happens again I will take note of it and repost. Or if I can find some kind of a log file containing that bluescreen error I will post. I have checked all cords, and they're all fine. Nothing's loose. My computer isn't overheating either. I've taken the case off for 3 whole days and haven't used the computer for those 3 days, which has had no effect. I've checked the connections inside and nothing's loose there either. I know there's nothing wrong with my monitor because my friend has 2 computers and it works perfectly on those computers. I don't understand how my computer could suddenly become so unstable. I'm almost certain that I have no viruses; I full-scan my pc everyday for nastys, and have strict firewall settings. Anyway, I don't see how it could be a virus anyway simply due to the fact that I had these problems right after I formatted, and before I even had the chance to install or copy anything or even connect to the internet. I know it has nothing to do with the way I formatted the computer too, I've been fixing computers for years. Sorry for rambling on, just making sure I don't leave anything out. Has anybody else had this problem? Can somebody please try to help me with this? Thank you :)

  • No Telnet login prompt when used over SSH tunnel

    - by SCO
    Hi there ! I have a device, let's call it d1, runnning a lightweight Linux. This device is NATed by my internet box/router, hence not reachable from the Internet. That device runs a telnet daemon on it, and only has root as user (no pwd). Its ip address is 192.168.0.126 on the private network. From the private network (let's say 192.168.0.x), I can do: telnet 192.168.0.126 Where 192.168.0.126 is the IP address in the private network. This works correctly. However, to allow administration, I'd need to access that device from outside of that private network. Hence, I created an SSH tunnel like this on d1 : ssh -R 4455:localhost:23 ussh@s1 s1 is a server somewhere in the private network (but this is for testing purposes only, it will endup somewhere in the Internet), running a standard Linux distro and on which I created a user called 'ussh'. s1 IP address is 192.168.0.48. When I 'telnet' with the following, let's say from c1, 192.168.0.19 : telnet -l root s1 4455 I get : Trying 192.168.0.48... Connected to 192.168.0.48. Escape character is '^]'. Connection closed by foreign host . The connection is closed after roughly 30 seconds, and I didn't log. I tried without the -l switch, without any success. I tried to 'telnet' with IP addresses instead of names to avoid reverse DNS issues (although I added to d1 /etc/hosts a line refering to s1 IP/name, just in case), no success. I tried on another port than 4455, no success. I gathered Wireshark logs from s1. I can see : s1 sends SSH data to c1, c1 ACK s1 performs an AAAA DNS request for c1, gets only the Authoritave nameservers. s1 performs an A DNS request, then gets c1's IP address s1 sends a SYN packet to c1, c1 replies with a RST/ACK s1 sends a SYN to c1, C1 RST/ACK (?) After 0.8 seconds, c1 sends a SYN to s1, s1 SYN/ACK and then c1 ACK s1 sends SSH content to d1, d1 sends an ACK back to s1 s1 retries AAAA and A DNS requests After 5 seconds, s1 retries a SYN to c1, once again it is RST/ACKed by c1. This is repeated 3 more times. The last five packets : d1 sends SSH content to s1, s1 sends ACK and FIN/ACK to c1, c1 replies with FIN/ACK, s1 sends ACK to c1. The connection seems to be closed by the telnet daemon after 22 seconds. AFAIK, there is no way to decode the SSH stream, so I'm really stuck here ... Any ideas ? Thank you !

  • Hibernating and booting into another OS: will my filesystems be corrupted?

    - by Ryan Thompson
    Suppose I have Windows and Linux installed on the same computer. If I hibernate Windows, can I boot into Linux without corrupting the Windows filesystem when I resume Windows? What about the other way around? What if I hibernate one, boot into the other, and mount the hibernated filesystem read/write? Read-only? If this is unsafe, is there any way to detect the hibernated state of the other OS and prevent mounting its filesystem? Basically, how far can I push this before it breaks, and how dangerous is it near the edge? I think I know the answers to some of the above questions, but for other ones, I have no idea, and for obvious reasons I have not tested this on my own computer. If someone has tested these, please enlighten the rest of us. I'm not necessarily looking for a specific answer to every question; I'll accept any response that answers a reasonable portion. EDIT: Let me clarify that when I say "hibernate," I mean the process of writing the contents of RAM to the hard disk and completely powering down the computer. In this state, powering the computer back on brings you through the BIOS and bootloader again, and you could theoretically select another operating system on a multi-boot system. Anyway, on with the original question: RESULTS Ok, after everyone's assurances that this would work, I tested it for myself. I set up Ubuntu to remount all ntfs filesystems and external drives read-only before hibernating. There was no need for a similar Windows setup because Windows does not read Linux filesystems. Then, I tried alternately hibernating one operating system and resuming the other, back and forth a few times. I even tried mounting the Windows filesystem from Ubuntu read-write, and creating a few files. Windows didn't complain when I resumed. So, in conclusion, you can more or less freely hibernate in a dual-boot Windows/Linux scenario. Note that I did not test a dual Linux/Linux co-hibernation situation. If you have two or more Linux installs and you hibernate one of them, you might be able to corrupt the filesystem by mounting it from another.

  • apcupsd on Linux does not report on APC BackUPS Pro 900

    - by lserni
    From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64). The USB port is detected, lsusb reports Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply and lsusb -v -s002:003 confirms and expands: Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 0.90 iManufacturer 1 American Power Conversion iProduct 2 Back-UPS RS 900G FW:879.L4 .I USB FW:L4 bNumConfigurations 1 Configuration Descriptor: [...] Interface Descriptor: [...] bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 1134 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 100 Device Status: 0x0000 (Bus Powered) The kernel recognizes this and duly sets up crw------- 1 root root 180, 96 Nov 4 16:11 /dev/usb/hiddev0 As far as I know, everything is as it should be.

This confirms that it's not the Microlink problem, or it would report the battery status, if precious little else. If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

  • Why apcupsd won't see the UPS connected to the USB posrt on FreeBSD 8.0 amd64

    - by Max Kosyakov
    Hello, Recently I installed an apcusbd on a FreeBSD 8.0 amd64 box via ports system. It installed perfectly but it won't run. Here what is says in the log: FATAL ERROR in generic-usb.c at line 636 Cannot find UPS device It appeared that HID driver picked the /dev/ugen4.2 which could cause the apcusb being unable to find the device. After I had discovered this, I rebuilt the kernel and removed the hid driver. Now it just shows "ugen4.2: <Tripp Lite> at usbus4" and no uhid0 device appears. Nevertheless the problem persisted. I tried to leave the DEVICE config setting blank --- won't help. Then I specified the particular device in the config, but it did not help either. Below you is the output of several commands that can provide some useful information on my case. server# /usr/local/etc/rc.d/apcupsd start Starting apcupsd. server# tail /var/log/messages | grep apcupsd Jun 17 22:30:00 server apcupsd[1520]: apcupsd FATAL ERROR in generic-usb.c at line 636 Cannot find UPS device -- For a link to detailed USB trouble shooting information, please see .

  • DNS settings for resolving Host name to IP not working?

    - by Hasas Ali Khan
    I want to access my IIS hosted application over LAN. First I installed a DNS server. The DNS configuration steps are: Go to DNS Manager - right click on System Name - click on configure a DNS Server. DNS Server wizard open -, click on next button - Select radio button "forward lookup zone" click on next button. In the second window. click on radio button "The server maintains the zone" and then click next. Give the zone name "example.com" Click on radio button, "Do Not allow dynamic updates". and then click next button. In the next window, click on radio button "No it should not forward query" and then click next button. Complete the configure a DNS server wizard and then click on finish button. After it is managing the DNS records: In DNS server wizard. open tree of forward lookup zone and right click on the new zone name "example.com" - properties and click on "Start of authority" and write values on text boxes serial number=1 primary server=systemname.domainname responsible person=hostmaster.domainname Click on server name, highlight domain name, click on edit button and enter IP address of the server where I host my application. Highlight new zone name and right click on it and click "New Host" option. In this window there are three text boxes: Name(user parent name if blank)=scoring Fully Qualified Domain Name=scoring.example.com IP Address= My IP Address and check on "Create associated pointer(PTR) record" and click on "Add Host" Host button and then click done button. I have host header for my application is "scoring" on port 80 and its working fine on server my application setting are I have change its, Advance setting --> Application Pool Identity --> Local System application can access on server with host name "scoring" but it can not access on machines on LAN. When I change LAN machine host file that is under, C:/windows/system32/driver/etc/host and edit it and enter host name with hosted machine IP like this: scoring 192.168.1.20 By making these changes I can run the application over LAN machines as I mentioned above DNS setting by which I can run App over LAN with out editing the client's host file. What mistake am I doing in this configuration?

  • SMTP for multiple domains on virtual interfaces

    - by Pawel Goscicki
    The setup is like this (Ubuntu 9.10): eth0: 1.1.1.1 name.isp.com eth0:0 2.2.2.2 example2.com eth0:1 3.3.3.3 example3.com example2.com and example3.com are web apps which need to send emails to their users. 2.2.2.2 points to example2.com and vice-versa (A/PTR). MX - Google. Google handles all incoming mail. 3.3.3.3 points to example3.com and vice-versa (A/PTR). MX - Google. Google handles all incoming mail. Requirements: Local delivery must be disabled (must deliver to MX specified server), so that the following works (note that there is no local user bob on the machine, but there is an existing bob email user): echo "Test" | mail -s "Test 6" [email protected] I need to be able to specify from which IP/domain name the email is delivered when sending an email. I fought with sendmail. With not much luck. Here's some debug info: sendmail -d0.12 -bt < /dev/null Canonical name: name.isp.com UUCP nodename: host a.k.a.: example2.com a.k.a.: example3.com ... Sendmail always uses canonical name (taken from eth0). I've found no way for it to select one of the UUCP codenames. It uses it for sending email: echo -e "To: [email protected]\nSubject: Test\nTest\n" | sendmail -bm -t -v [email protected]... Connecting to [127.0.0.1] via relay... 220 name.isp.com ESMTP Sendmail 8.14.3/8.14.3/Debian-9ubuntu1; Wed, 31 Mar 2010 16:33:55 +0200; (No UCE/UBE) logging access from: localhost(OK)-localhost [127.0.0.1] >>> EHLO name.isp.com I'm ok with other SMTP solutions. I've looked briefly at nbsmtp, msmtp and nullmailer but I'm not sure thay can deal with disabling local delivery and selecting different domains when sending emails. I also know about spoofing sender field by using mail -a "From: <[email protected]>" but it seems to be a half-solution (mails are still sent from isp.com domain instead of proper example2.com, so PTR records are unused and there's more risk of being flagged as spam/spammer).

  • Ubuntu Server 12.04 CPU Load

    - by zertux
    I have a Server (2x Hexa-Core Xeon E5649 2.53GHz w/HT with 32GB RAM and 20000 GB Bandwidth) running Ubuntu Server 12.04 LTS. The server runs LAMP and serves one website only, the estimated number of users is to be ~ 15,000 at the same time. At the moment i have around 2000 users online each of them runs 50 MySQL queries (small values mostly select and insert) from the beginning until the end of the session. Server CPU Load is high at this number of connections while the RAM usage is almost 1GB out of 32GB its worth mentioning that the server was running very fast with no problems at all but am concerned about the load average. http://s12.postimage.org/z7hi6mz3h/photo.png top - 03:02:43 up 9 min, 2 users, load average: 50.83, 30.14, 12.83 Tasks: 432 total, 1 running, 430 sleeping, 0 stopped, 1 zombie Cpu(s): 0.1%us, 0.2%sy, 0.0%ni, 66.5%id, 33.1%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 32939992k total, 3111604k used, 29828388k free, 84108k buffers Swap: 2048280k total, 0k used, 2048280k free, 1621640k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2860 root 20 0 25820 2288 1420 S 3 0.0 0:11.18 htop 1182 root 20 0 0 0 0 D 2 0.0 0:01.46 kjournald 1935 mysql 20 0 12.3g 161m 7924 S 1 0.5 102:31.45 mysqld 11 root 20 0 0 0 0 S 0 0.0 0:00.38 kworker/0:1 1822 www-data 20 0 247m 25m 4188 D 0 0.1 0:01.81 apache2 2920 www-data 20 0 0 0 0 Z 0 0.0 0:01.20 apache2 <defunct> 2942 www-data 20 0 247m 23m 3056 D 0 0.1 0:00.20 apache2 3516 www-data 20 0 247m 23m 3028 D 0 0.1 0:00.06 apache2 3521 www-data 20 0 247m 23m 3020 D 0 0.1 0:00.09 apache2 3664 www-data 20 0 247m 23m 3132 D 0 0.1 0:00.09 apache2 3674 www-data 20 0 247m 23m 3252 D 0 0.1 0:00.06 apache2 3713 www-data 20 0 247m 23m 3040 D 0 0.1 0:00.09 apache2 1 root 20 0 24328 2284 1344 S 0 0.0 0:03.09 init 2 root 20 0 0 0 0 S 0 0.0 0:00.00 kthreadd 3 root 20 0 0 0 0 S 0 0.0 0:00.01 ksoftirqd/0 6 root RT 0 0 0 0 S 0 0.0 0:00.00 migration/0 7 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/0 8 root RT 0 0 0 0 S 0 0.0 0:00.00 migration/1 9 root 20 0 0 0 0 S 0 0.0 0:00.00 kworker/1:0 root@server:~/codes# vmstat 1 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 19 0 0 29684012 86112 1689844 0 0 19 590 254 231 48 0 47 5 23 0 0 29704812 86128 1697672 0 0 4 320 11100 8121 77 1 22 0 33 0 0 29671044 86156 1705308 0 0 0 5440 13190 9140 95 1 4 0 33 3 0 29670088 86160 1706288 0 0 0 32932 12275 7297 99 0 1 0 35 0 0 29693456 86188 1710724 0 0 4 676 12701 7867 98 1 1 0 ^C I have not changed any of the default configurations that comes with Ubuntu.

  • Write STDOUT & STDERR to a logfile, also write STDERR to screen

    - by Stefan Lasiewski
    I would like to run several commands, and capture all output to a logfile. I also want to print any errors to the screen (or optionally mail the output to someone). Here's an example. The following command will run three commands, and will write all output (STDOUT and STDERR) into a single logfile. { command1 && command2 && command3 ; } > logfile.log 2>&1 Here is what I want to do with the output of these commands: STDERR and STDOUT for all commands goes to a logfile, in case I need it later--- I usually won't look in here unless there are problems. Print STDERR to the screen (or optionally, pipe to /bin/mail), so that any error stands out and doesn't get ignored. It would be nice if the return codes were still usable, so that I could do some error handling. Maybe I want to send email if there was an error, like this: { command1 && command2 && command3 ; } logfile.log 2&1 || mailx -s "There was an error" [email protected] The problem I run into is that STDERR loses context during I/O redirection. A '2&1' will convert STDERR into STDOUT, and therefore I cannot view errors if I do 2 error.log Here are a couple juicier examples. Let's pretend that I am running some familiar build commands, but I don't want the entire build to stop just because of one error so I use the '--keep-going' flag. { ./configure && make --keep-going && make install ; } > build.log 2>&1 Or, here's a simple (And perhaps sloppy) build and deploy script, which will keep going in the event of an error. { ./configure && make --keep-going && make install && rsync -av --keep-going /foo devhost:/foo} > build-and-deploy.log 2>&1 I think what I want involves some sort of Bash I/O Redirection, but I can't figure this out.

  • How to know the source of certain TCP traffic on AIX

    - by A.Rashad
    We have two AIX boxes, one for production system and another for testing. both systems are running ATM machine switches, where the ATM device is connected via TCP socket. we had an issue on production system where the machine would power off or get disconnected but the netstat -na | grep <IP of machine > would still mention that the socket is up when simulated that case on the UAT environment, the problem did not happen, where the socket would terminate in 3 to 5 minutes. when sniffed on the traffic between the machine and ATM we found that no traffic takes place on production while there is some sort of heartbeat on UAT. but it is not initiated by the application. $>tcpdump | grep -v "10.2.2.71" | grep -v "HSRP" | grep "10.3.1.30" tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en6, link-type 1, capture size 96 bytes 09:08:13.323421 IP server073.afs3-callback > 10.3.1.30.impera: . 278204201:278204202(1) ack 3307884029 win 164 09:08:13.335334 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:08:23.425771 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:08:23.425789 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 09:09:13.628985 IP server073.afs3-callback > 10.3.1.30.impera: . 0:1(1) ack 1 win 164 09:09:13.633900 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:09:23.373634 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:09:23.373647 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 while on production, that traffic is not there. we want to know where this traffic is initiated from to implement on production to sense disconnection our comms parameters are: tcp_keepcnt = 2 tcp_keepidle = 100 tcp_keepinit = 150 tcp_keepintvl = 150 tcp_finwait2 = 1200 can anyone help?

  • Apache Alias subfolder and starting with dot

    - by MauricioOtta
    I have a multi purpose server running ArchLinux that currently serves multiple virtual hosts from /var/www/domains/EXAMPLE.COM/html /var/www/domains/EXAMPLE2.COM/html I deploy those websites (mostly using Kohana framework) using a Jenkins job by checking out the project, removes the .git folder and ssh-copy the tar.gz to /var/www/domains/ on the server and untars it. Since I don't want to have to re-install phpMyAdmin after each deploy, I decided to use an alias. I would like the alias to be something like /.tools/phpMyAdmin/ so I could have more "tools" later if I wanted to. I have tried just changing the default httpd-phpmyadmin.conf that was installed by following the official WIKI: https://wiki.archlinux.org/index.php/Phpmyadmin Alias /.tools/phpMyAdmin/ "/usr/share/webapps/phpMyAdmin" <Directory "/usr/share/webapps/phpMyAdmin"> AllowOverride All Options FollowSymlinks Order allow,deny Allow from all php_admin_value open_basedir "/var/www/:/tmp/:/usr/share/webapps/:/etc/webapps:/usr/share/pear/" </Directory> Changing only that, doesn't seem to work with my current setup on the server, and apache forwards the request to the framework which 404s (as there's no route to handle /.tools/phpAdmin). I have Mass Virtual hosting enable and setup like this: # # Use name-based virtual hosting. # NameVirtualHost *:8000 # get the server name from the Host: header UseCanonicalName On # splittable logs LogFormat "%{Host}i %h %l %u %t \"%r\" %s %b" vcommon CustomLog logs/access_log vcommon <Directory /var/www/domains> # ExecCGI is needed here because we can't force # CGI execution in the way that ScriptAlias does Options FollowSymLinks ExecCGI AllowOverride All Order allow,deny Allow from all </Directory> RewriteEngine On # a ServerName derived from a Host: header may be any case at all RewriteMap lowercase int:tolower ## deal with normal documents first: # allow Alias /icons/ to work - repeat for other aliases RewriteCond %{REQUEST_URI} !^/icons/ # allow CGIs to work RewriteCond %{REQUEST_URI} !^/cgi-bin/ # do the magic RewriteCond %{SERVER_NAME} ^(www\.|)(.*) RewriteRule ^/(.*)$ /var/www/domains/${lowercase:%2}/html/$1 ## and now deal with CGIs - we have to force a MIME type RewriteCond %{REQUEST_URI} ^/cgi-bin/ RewriteRule ^/(.*)$ /var/www/domains/${lowercase:%{SERVER_NAME}}/cgi-bin/$1 [T=application/x-httpd-cgi] There is also nginx running on this server on port 80 as a reverse proxy for Apache: location ~ \.php$ { proxy_pass http://127.0.0.1:8000; } Everything else was setup by following the official WIKI so I don't think those would cause trouble. Do I need to have the alias for phpMyAdmin setup along the mass virtual hosting or can it be in a separate include file for that alias to work?

  • JNDI Datasource Problem on Tomcat 6, Hibernate

    - by Asuman AKYILDIZ
    Hello; I am using Tomcat 6 as application server, Struts-Hibernate and MyEclipse 6.0. My application uses JDBC driver but I should modify it to use JNDI Datasource. I followed steps as described in tomcat 6.0 howto tutorial. I defined my resource in tomcatconf: <Resource name="jdbc/ats" global="jdbc/ats" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@//localhost:1521/MISDEV" username="TEST" password="TEST" maxActive="20" maxIdle="10" maxWait="-1" validationQuery="SELECT 1 from dual" removeAbandoned="true" removeAbandonedTimeout="30" logAbandoned="false"/> I gave reference in my application web.xml: <resource-ref> <description>Oracle Datasource example</description> <res-ref-name>jdbc/ats</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> And I defined datasource-dialect in my hibernate-cfg.xml <property name="connection.datasource">java:comp/env/jdbc/ats</property> <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property> But when I create hibernate session, it can not open the connection: 09:18:11,322 ERROR JDBCExceptionReporter:72 - Connections could not be acquired from the underlying database! org.hibernate.exception.GenericJDBCException: Cannot open connection I also tried to set the properties at runtime: Configuration configuration = new Configuration(); configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect"); //configuration.setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/ats"); configuration.setProperty("hibernate.current_session_context_class", "thread"); configuration.setProperty("hibernate.connection.provider_class", "org.hibernate.connection.C3P0ConnectionProvider"); configuration.setProperty("hibernate.show_sql", "true"); sessionFactory = configuration.configure().buildSessionFactory(); It does not open connection again. But, when I use JDBC driver it works: Configuration configuration = new Configuration(); configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect"); //configuration.setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/ats"); configuration.setProperty("hibernate.connection.url", "jdbc:oracle:thin:@//localhost:1521/MISDEV"); configuration.setProperty("hibernate.connection.username", "test"); configuration.setProperty("hibernate.connection.password", "test"); configuration.setProperty("hibernate.connection.driver_class", "oracle.jdbc.OracleDriver"); configuration.setProperty("hibernate.transaction.factory_class", "org.hibernate.transaction.JDBCTransactionFactory"); configuration.setProperty("hibernate.current_session_context_class", "thread"); configuration.setProperty("hibernate.connection.provider_class", "org.hibernate.connection.C3P0ConnectionProvider"); configuration.setProperty("hibernate.show_sql", "true"); sessionFactory = configuration.configure().buildSessionFactory(); I have been searching for 3 days and no success. What may be de problem?

  • Specifying prerequisites for Puppet custom facts?

    - by larsks
    I have written a custom Puppet fact that requires the biosdevname tool to be installed. I'm not sure how to set things up correctly such that this tool will be installed before facter tries to instantiate the custom fact. Facts are loaded early on in the process, so I can't simply put a package { biosdevname: ensure => installed } in the manifest, since by the time Puppet gets this far the custom fact has already failed. I was curious if I could resolve this through Puppet's run stages. I tried: stage { pre: before => Stage[main] } class { biosdevname: stage => pre } And: class biosdevname { package { biosdevname: ensure => installed } } But this doesn't work...Puppet loads facts before entering the pre stage: info: Loading facts in physical_network_config ./physical_network_config.rb:33: command not found: biosdevname -i eth0 info: Applying configuration version '1320248045' notice: /Stage[pre]/Biosdevname/Package[biosdevname]/ensure: created Etc. Is there any way to make this work? EDIT: I should make it clear that I understand, given a suitable package declaration, that the fact will run correctly on subsequent runs. The difficulty here is that this is part of our initial configuration process. We're running Puppet out of kickstart and want the network configuration to be in place before the first reboot. It sounds like the only workable solution is to simply run Puppet twice during the initial system configuration, which will ensure that the necessary packages are in place. Also, for Zoredache: # This produces a fact called physical_network_config that describes # the number of NICs available on the motherboard, on PCI bus 1, and on # PCI bus 2. The fact value is of the form <x>-<y>-<z>, where <x> # is the number of embedded interfaces, <y> is the number of interfaces # on PCI bus 1, and <z> is the number of interfaces on PCI bus 2. em = 0 pci1 = 0 pci2 = 0 Dir['/sys/class/net/*'].each { |file| devname=File.basename(file) biosname=%x[biosdevname -i #{devname}] case when biosname.match('^pci1') pci1 += 1 when biosname.match('^pci2') pci2 += 1 when biosname.match('^em[0-9]') em += 1 end } Facter.add(:physical_network_config) do setcode do "#{em}-#{pci1}-#{pci2}" end end

  • Looking for a NTP Server Software for Windows

    - by Simon
    I'm looking for a, preferably free, NTP Server for Windows Server 2003/2008. We have already tried the built in Windows Time Server, but our tests did show that it is not very accurate, we see time differences up to 500ms. The max time difference we can allow for our application is ~100ms. Now we have already used the Meinberg NTPd for Windows. It works great except we have one big issue with it: If there is a network connection problem between the client and server, the ntp server is in a panic state It won't give the client a new time until we restart the ntp service. This is a big issue which has caused us some trouble. It was working fine for months until there was a network problem we didn't notice, we only noticed it after a week when the time difference was already 30 sec. on the clients. So please suggest some alternative NTP Server for windows. I did Google but I get a lot of unrelated search results. Edit: So far the ntpd windows version was very accurate and I'd like to stick with it. The only problem is the "panic state" after a network disconnect. Maybe some knows here what the cause of this is and how to fix it. Also, I forgot to mention that we have a server/client setup like this: Server1 -- Server2 -- Server3 -- Client1 -- Client2 -- Client3 So Server2 gets its time from Server1, Server3 gets its time from Server2, and the Clients get their time from Server3. Also, there are clients connected directly to Server2. It is important that all Servers and Clients have the exact same time (within ~100ms) Now there was a network problem with Server3 and its clients. The servers run the ntpd port for Windows, which acts as NTP server and client. The clients have Dimension4 as NTP client. After the network problem, the error message in D4 was something like this (out the top of my head, don't have the exact error message): Server response: The server is in a panic state (could not sync clock) I read through the ntpd docs, and the only mention of "panic" is when the time difference is 10000 seconds which will cause to exit the ntpd server but this was not the case. Also there is a "-g" command line switch to disable the panic exit, but it is already set by default. Any ideas what could cause the panic state and how to get rid of it next time?

  • Need an excel macro to produce a formatted text file

    - by user139238
    I am just learning how to make macros and I found a macro that nearly does what I need it to do, which is output a text file from Excel. What I need it to do is output this in a .mhd format, which I have done, and then take all the data written in the #fnum cells and place a return after each in the Excel file. Essentially I just need all the data to have their a specific line in the text file. I am certain there is an elegant way to go about this, but I can't seem to get it. Sub CreateFile() Do While Not IsEmpty(ActiveCell.Offset(0, 1)) MyFile = ActiveCell.Value & ".mhd" 'set and open file for output fnum = FreeFile() Open MyFile For Output As fnum 'use Print when you want the string without quotation marks Print #fnum, ActiveCell.Offset(0, 5); " " & ActiveCell.Offset(0, 6); " " & ActiveCell.Offset(0, 7); " " & ActiveCell.Offset(0, 8); " " & ActiveCell.Offset(0, 9); " " & ActiveCell.Offset(0, 10); " " & ActiveCell.Offset(0, 11); " " & ActiveCell.Offset(0, 12); " " & ActiveCell.Offset(0, 13); " " & ActiveCell.Offset(0, 14); " " & ActiveCell.Offset(0, 15); " " & ActiveCell.Offset(0, 16); " " & ActiveCell.Offset(0, 17); " " & ActiveCell.Offset(0, 18); " " & ActiveCell.Offset(0, 19); " " & ActiveCell.Offset(0, 20); " " & ActiveCell.Offset(0, 21); " " & ActiveCell.Offset(0, 22); " " & ActiveCell.Offset(0, 23); " " & ActiveCell.Offset(0, 24); " " & ActiveCell.Offset(0, 25); " " & ActiveCell.Offset(0, 26) Close #fnum ActiveCell.Offset(1, 0).Select Loop End Sub

  • UAE and the mysteries of unreachable websites

    - by 0plus1
    I write here because I'm really lost, please stay with me because it's not easy to explain. A company asked me to set-up a private server, now I'm a programmer so I got a solution with technical support and cpanel which helped me to setup everything and it's working smoothless. I'm by no means a professional sysadmin, but I have a fair knowledge of server configurations, but this problem is way over my knowledge, and apparently way over the knowledge of most sysadmins, I really hope that here I'll find someone with enough experience to help me or at least give me more insight. Now this company for which I'm consulting operates in the UAE (United Arab Emirates) and from there the server is almost unreachable. It started with ns not registering in the UAE, after a week that sorted itself out and now the site is indeed reachable, but it takes almost 2 minutes to load a webpage with one line of text. Emails go in timeout. The domain currently parked there has been bought appositely for tests, the main one that was supposed to go there, after a catastrophic week has been transferred to a shared hosting solution in the UK, and from there it works like a charme. Now after doing some research I discovered that I'm not alone in this, there are several reports of webmasters discovering that their website is not reachable inside the UAE, and mind this has nothing to do with the state-wide block of questionable sites, because in that case an error message appears, this seems to be related to the infrastructure of the UAE, which apparently reroutes everything through their own "fake" internet. Apparently new servers with their own IP are not recognized (yet?) by the UAE infrastructure, while shared hosting solutions seeing that they operates tons of other websites are more likely to be part of the UAE network. Now my questions are: 1) Has someone a real explanation for this? The only thing I can think of is that the server is on a new IP that is not yet recognized by the UAE, but that doesn't explain why it loads (even if after 2 minutes). I don't have any help from within the UAE as the only people that are "experts" are questionable companies that simply try to sell their own services. 2) If there is really some kind of block of new servers, is it possible to know before if a server is reachable from within the UAE, currently this is not a ns problem as even accessing the server with its IP result in a 2 minute wait. 3) Can it be that the problem lies somewhere else? There are some tests that I can perform? I'm not physically in the UAE, but I can ask the people there, or use teamviewer. Could it be some misconfiguration on the server (mind that the site works EVERYWHERE else in the world). Thank you for ANY kind of help

  • Building an SSL server farm

    - by dan
    I'm interested in building the the architecture in the article referenced below. I currently have a modestly-priced layer-4 load balancer and my application servers are the SSL endpoints. I want to put an SSL server farm in between my load balancer and my app servers. Then I will put another inexpensive load balancer between the SSL farm and my app servers, to do layer-7 routing. My web application has a fairly high amount of consumer traffic, that 6 servers can handle at about 50% capacity. Additionally, I have infrastructure traffic that is several orders of magnitude heavier than my consumer traffic. This is data coming in from all over the world that must integrate with my web application in real time. In total I have 18 app servers to handle all the traffic, plus 6 database servers. I will be adding 6 more app servers over the next 2 weeks and another 6 the 2 weeks after that. Conservatively, I estimate I will need to scale to 120 servers by the end of the year. My motivation right now is to separate the consumer traffic from the infrastructure traffic. The consumer traffic is higher priority than the infrastructure traffic and I cannot allow a stampede on the infrastructure side to take down my consumer-facing servers. Having a website that is always up is the top priority. However if there is a failure in one of the consumer app servers, I want to route that traffic to the servers designated for infrastructure traffic. The complication is that all the traffic is addressed using the same hostname and is nearly 100% https. The only way in my case to distinguish infrastructure from consumer traffic is by URL (poor architecture I inherited), so I need a layer 7 load balancer to be able to route. However for that to work I need either a fancy hardware-based SSL terminator or an SSL server farm as described above. Because my user base is rapidly scaling, I worry that if I go down the hardware path it will become very expensive very fast, especially since I will need 4 of everything for high availability (2 identical setups in 2 facilities). Meanwhile, the above diagram seems very flexible and more horizontally scalable. Has anyone built this before? Are there pre-built configurations? What considerations should I make and what software should I use (I've heard of people using apache with mod-ssl, nginx, and stunnel)? Also, when does it make sense to buy an expensive load balancer vs building an SSL server farm? http://1wt.eu/articles/2006_lb/index_05.html

  • Pinning based on origin of a reprepro repository.

    - by Shtééf
    I'm on Ubuntu 10.04, and trying to set up a repository using reprepro. I'd also like the pin everything in that repository to be preferred over anything else, even if packages are older versions. (It will only contain a select set of packages.) However, I cannot seem to get the pinning to work, and believe it has something to do with the repository side of things, rather than the apt configuration on the client. I've taken the following steps to set up my repository Installed a web server (my personal choice here is Cherokee), Created the directory /var/www/apt/, Created the file conf/distributions, like so: Origin: Shteef Label: Shteef Suite: lucid Version: 10.04 Codename: lucid Architectures: i386 amd64 source Components: main Description: My personal repository Ran reprepro export from the /var/www/apt/ directory. Now on any other machine, I can add this (empty) repository over HTTP to my /etc/apt/sources.list, and run apt-get update without any errors: Ign http://archive.lan lucid Release.gpg Ign http://archive.lan/apt/ lucid/main Translation-en_US Get:1 http://archive.lan lucid Release [2,244B] Ign http://archive.lan lucid/main Packages Ign http://archive.lan lucid/main Sources Ign http://archive.lan lucid/main Packages Ign http://archive.lan lucid/main Sources Hit http://archive.lan lucid/main Packages Hit http://archive.lan lucid/main Sources In my case, now I want to use an old version of Asterisk, namely Asterisk 1.4. I rebuilt the asterisk-1:1.4.21.2~dfsg-3ubuntu2.1 package from Ubuntu 9.04 (with some small changes to fix dependencies) and uploaded it to my repository. At this point I can see the new package in aptitude, but it naturally prefers the newer Asterisk 1.6 currently in the Ubuntu 10.04 repositories. To try and fix that, I have created /etc/apt/preferences.d/personal like so: Package: * Pin: release o=Shteef Pin-Priority: 1000 But when I try to install the asterisk package, it will still prefer the 1.6 version over my own 1.4 version. This is what apt-cache policy asterisk shows: asterisk: Installed: (none) Candidate: 1:1.6.2.5-0ubuntu1 Version table: 1:1.6.2.5-0ubuntu1 0 500 http://nl.archive.ubuntu.com/ubuntu/ lucid/universe Packages 1:1.4.21.2~dfsg-3ubuntu2.1shteef1 0 500 http://archive.lan/apt/ lucid/main Packages Clearly, it is not picking up my pin. In fact, when I run just apt-cache policy, I get the following: Package files: 100 /var/lib/dpkg/status release a=now 500 http://archive.lan/apt/ lucid/main Packages origin archive.lan 500 http://security.ubuntu.com/ubuntu/ lucid-security/multiverse Packages release v=10.04,o=Ubuntu,a=lucid-security,n=lucid,l=Ubuntu,c=multiverse origin security.ubuntu.com [...] Unlike Ubuntu's repository, apt doesn't seem to pick up a release-line at all for my own repository. I'm suspecting this is the cause why I can't pin on release o=Shteef in my preferences file. But I can't find any noticable difference between my repository's Release files and Ubuntu's that would cause this. Is there a step I've missed or mistake I've made in setting up my repository?

  • Win7 x64 unresponsive for a minute or so. HD failing?

    - by Gaia
    On a fully updated Win7 x64, every so often the system stalls for a minute or so. This has been going on for a couple months now. By stalling I mean the mouse responds and I can move windows around, but any window, any program, that is open becomes whiteish when I select it AND any new programs will not open. It doesn't matter what kind of program it is. When the stall stops all clicks I made (open new programs for example) take effect. Nothing shows up consistently (as in every time this happens) in the event log. Today though I was able to find something, but it doesn't reveal much other than the "system was unresponsive". It's a 7009 for "A timeout was reached (30000 milliseconds) while waiting for the Windows Error Reporting Service service to connect." It doesn't matter if I have any USB devices plug-in or not. I've ran Microsoft Security Essentials and Malwarebytes. While the machine is unresponsive, I've noticed that Drive D (the other partition on the single internal HD in this laptop) is displayed like this in explorer. This never occurs with Drive C or any other drive on the machine. . SMART report for the physical drive: Read benchmark by HD Tune 5 Pro, probably the most telling piece of the puzzle. Isn't this alone enough to see there is a problem with the drive, regardless of whether the unresponsiveness is caused by such purported problem? Here is a short hardware report: Computer: LENOVO ThinkPad T520 CPU: Intel Core i5-2520M (Sandy Bridge-MB SV, J1) 2500 MHz (25.00x100.0) @ 797 MHz (8.00x99.7) Motherboard: LENOVO 423946U Chipset: Intel QM67 (Cougar Point) [B3] Memory: 8192 MBytes @ 664 MHz, 9.0-9-9-24 - 4096 MB PC10600 DDR3 SDRAM - Samsung M471B5273CH0-CH9 - 4096 MB PC10600 DDR3 SDRAM - Patriot Memory (PDP Systems) PSD34G13332S Graphics: Intel Sandy Bridge-MB GT2+ - Integrated Graphics Controller [D2/J1/Q0] [Lenovo] Intel HD Graphics 3000 (Sandy Bridge GT2+), 3937912 KB Drive: ST320LT007, 312.6 GB, Serial ATA 3Gb/s Sound: Intel Cougar Point PCH - High Definition Audio Controller [B2] Network: Intel 82579LM (Lewisville) Gigabit Ethernet Controller Network: Intel Centrino Advanced-N 6205 AGN 2x2 HMC OS: Microsoft Windows 7 Professional (x64) Build 7601 The drive less than 1 year old. Do I have a defective drive? Seagate Tools diag says there is nothing wrong with the drive... UPDATE: I noticed that the windows error reporting service entered the running state then the stopped state and the space between the two events was exactly 2 minutes. Which error it was trying to report I don't know. I check the "Reliability Monitor" and it shows no errors to be reported. I've disabled the windows error reporting service to see if the problem stops.

  • Routing RFC1918 addresses through dd-wrt via a switch

    - by espenfjo
    I am a bit stuck with an experiment of mine. I have a network looking somewhat like this. | Internet | | ---- |Switch| ---- | | Server w/pub IP | DD-WRT router 192.168.1.1 | | RFC1918 clients 192.168.1.0/24 What I want is for the RFC1918 clients to speak directly with each others. On the server with the public IP I have this route: 192.168.1.0/24 dev eth0 scope link and can see that packets are infact reaching the dd-wrt router for 192.168.1.1, even though if I get no answer. Trying to reach one of the RFC1918 clients from the public IP server will get no result, as the dd-wrt router is not announcing that network on to its external interface (arp who-has 192.168.1.107 tell xxx.xxx.xxx.xxx, but no answer). The router being an WLAN dd-wrt router has of course a load of routes, VLANs and interfaces: xxx.xxx.xxx.1 dev vlan2 scope link 192.168.1.0/24 dev br0 proto kernel scope link src 192.168.1.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.244 84.215.64.0/18 dev vlan2 proto kernel scope link src xxx.xxx.xxx.xxx 169.254.0.0/16 dev br0 proto kernel scope link src 169.254.255.1 127.0.0.0/8 dev lo scope link 0.0.0.0 via xxx.xxx.xxx.1 dev vlan2 xxx.xxx.xxx.xxx being the public IP, and xxx.xxx.xxx.1 being the default route for the public IP. I am not sure where to continue with this. I would recon that I both need routing on the dd-wrt router, as well as some iptables magic? Why do something this complex? Why not ;) Also, do not mind that "Internet" can get RFC1918 traffic, it wont go outside of the walls. EDIT 1: Following the tip from stew I do indeed get the correct ARP flowing. And adding an iptables rule for allowing traffic from that specific public IPd machine I get traffic between the systems! Oddly enough though, the speed I get from Server w/pub IP - RFC1918 clients are the same as if the traffic were routed out onto the Internet and back. Edit 2: Ok, disconnecting the external Internet connection will still give the same, crappy transfer speed. So it has to be something else. Edit 3: Ok, I guess there are other reasons for this crappy speed. Case closed. :)

  • Command-line connect to wired network for Ubuntu

    - by Tim
    I like to know how to use command-line to connect to a wired network in general for Ubuntu 8.10? In my case, I connect a cable to my laptop but it doesn't work with my WICD. So I like to try command-line method. Here is the ifconfig of my network adapters: $ ifconfig eth0 Link encap:Ethernet HWaddr 00:c0:9f:8d:23:74 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:19 Base address:0x1800 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4457 errors:0 dropped:0 overruns:0 frame:0 TX packets:4457 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:493002 (493.0 KB) TX bytes:493002 (493.0 KB) wlan0 Link encap:Ethernet HWaddr 00:0e:9b:ab:56:19 UP BROADCAST NOTRAILERS PROMISC ALLMULTI MTU:576 Metric:1 RX packets:1508929 errors:0 dropped:0 overruns:0 frame:0 TX packets:768144 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:806027375 (806.0 MB) TX bytes:78834873 (78.8 MB) wlan0:avahi Link encap:Ethernet HWaddr 00:0e:9b:ab:56:19 inet addr:169.254.5.92 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST NOTRAILERS PROMISC ALLMULTI MTU:576 Metric:1 wmaster0 Link encap:UNSPEC HWaddr 00-0E-9B-AB-56-19-00-00-00-00-00-00-00-00-00-00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Thanks and regards!

  • Lag spikes at full CPU usage, maybe video card

    - by Roberts
    I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).
