  • Apache can't be restarted after changes to the configuration file

    - by Sharifhs
    Hello, I can't successfully configure the apache and php configuration files, can anybody help me in this way? Apache 2.2.16 (win32-x86-no_ssl.msi) was installed into “C:\Apache2.2 “location. Then PHP 5.3.3 (VC9 x86 Thread Safe) zip file was downloaded and extracted on “C:\php” location. From “C:\php” I renamed the “php.ini-development” file into “php.ini” “php.ini” file was opened with notepad, and modified as: doc_root = "C:\Apache2.2\htdocs" extension_dir = "C:\php\ext" The following lines were added to the Apache's configuration file “httpd.conf”: LoadModule php5_module "C:/php/php5apache2_2.dll" AddType application/x-httpd-php .php PHPIniDir "C:/php" N.B.: Thanks all for comments and answer, but I can't reply none your comments, I don't know why. May be I'm not privileged to put any comment as I'm new here (is it the case?)! That's why I'm to edit my post to reply you all. Tell me what can I do? @ jer.salamon: do you want me to post full httpd.conf file? It'll be longer then! @ davr: the server started first, but when I configured those files, its never started again @jer.salamon: did you mean keeping this way: doc_root = extension_dir = "ext" It not yet restared!

  • finding the best network latency between two countries

    - by Yoav Aner
    I know there are many tools to test for bandwidth and latency, but they all rely on having at least one host from which you can run those tests. I wonder whether there's an online source or some other way to guestimate the latency or speed between two countries (in general). For example, would a customer in Japan get lower latency if the server is located in Singapore or Australia? Is a user in India likely to get higher download speed from a server in the UK or in the US? Are there any online resources or some clever ways to answer those questions with a reasonable degree of accuracy? [UPDATE]: Thanks for the great suggestions from Raffael Luthiger. I didn't know about those looking glass servers. The submarine cable maps were also really cool to discover (Thanks to Jesper Mortensen). Also seems really wise if I could ask those network professional in the area for their experience, but obviously I don't have access to those. At least some of them are on SF :) However, I'm still a little unsure how to combine those resources to give me some measurements. This is the information I have: Two countries (A,B). I do have IP addresses of customers in country A (I can obtain those from the web server log files for example). Presumably I can find some looking glass servers in country B and run a trace to those IPs. What's the best measurements to use? Are there any scripts that help automate at least some of this process?

  • Resize a RAID 1 volume on OS X Snow Leopard - how? (Note: software raid)

    - by Emmel
    I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OS X 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

  • App for family tech support tracking?

    - by slothbear
    I do tech support for several groups within my family. They usually have a document or notebook of questions for me. They often record my advice, but then ask me again later. Some communications are by email (nice record for me, although they never think to search). Some sessions are in person, usually with a followup email from me for the record. Which they forget about. I'm not trying to force them to be more 'professional', but I would like to streamline my support a bit, and give them a place to look for past answers. Some of them would like a standard place like that, rather than reasking me the same questions. The solution has to be free. And web-based, although email-in for questions would be great. I'll be doing most (all?) updating of the system. Mobile/iPhone access would be nice, but not required. Ideally, a system with topics and responses would be good, but I'd need a way to promote one response as 'the answer'.

  • iPhone Lag Terrible - SLOW - What's going on with the iPhone OS?

    - by Sam Schutte
    I've had my iPhone 3G for about a year now, and it seems like at least once a month, it gets bogged down and gets slower and slower - horrible lag when typing, going back to the home screen or opening an app can take 20 seconds. Has anyone else run into this and found "the" solution. What you always read on other boards is to reboot the handset (hold down home and the power button), but that doesn't improve anything for me. I've reinstalled the OS like 5 times now, and I'm getting pretty sick of doing it so often. And I don't buy that it's a hardware issue really, since it works fine for weeks after a fresh install. Anyone have a solution or an idea of what specific actions cause this kind of evident data corruption (OS corruption?) and slowness? Note - I'm looking for specific things here. That is, has anyone done the research to see exactly what on the phone operating system is getting messed up that causes this lag (which is discussed all over the internet, with no working solutions). I don't own a mac, so I can't delve into the guts of the iPhone very well to see what's up with it... Some additional info: Reboots (hold down power/home) and "Sleeps" (slide off) do nothing. Only fresh re-installs help I only have about 15 apps installed - sometimes you see the answer to uninstall apps if you have too many, I'd hope that 15 isn't too many, and even when I've had none installed, it still gets hung up after a period of time. This phone is not jailbroken, and it is running the 3.0.1 release.

  • How does Windows 7 taskbar "color hot-tracking" feature calculate the colour to use?

    - by theyetiman
    This has intrigued me for quite some time. Does anyone know the algorithm Windows 7 Aero uses to determine the colour to use as the hot-tracking hover highlight on taskbar buttons for currently-running apps? It is definitely based on the icon of the app, but I can't see a specific pattern of where it's getting the colour value from. It doesn't seem to be any of the following: An average colour value from the entire icon, otherwise you would get brown all the time with multi-coloured icons like Chrome. The colour used the most in the image, otherwise you'd get yellow for the SQL Server Management Studio icon (6th from left). Also, the Chrome icon used red, green and yellow in equal measure. A colour located at certain pixel coordinates within the icon, because Chrome is red -indicating the top of the icon - and Notepad++ (2nd from right) is green - indicating the bottom of the icon. I asked this question on ux.stackoverflow.com and it got closed as off-topic, but someone answered with the following: As described by Raymond Chen in this MSDN blog article: Some people ask how it's done. It's really nothing special. The code just looks for the predominant color in the icon. (And, since visual designers are sticklers for this sort of thing, black, white, and shades of gray are not considered "colors" for the purpose of this calculation.) However I wasn't really satisfied with that answer because it doesn't explain how the "predominant" colour is calculated. Surely on the SQL Management Studio icon, the predominant colour, to my eyes at least, is yellow. Yet the highlight is green. I want to know, specifically, what the algorithm is.

  • Configured Samba to join our domain, but logon fails from Windows machine

    - by jasonh
    I've configured a Fedora 11 installation to join our domain. It seems to join successfully (though it reports a DNS update failure) but when I try to access \\fedoraserver.test.mycompany.com I'm prompted for a password. So I enter adminuser and the password and that fails, so I try test.mycompany.com\adminuser and that too fails. What am I missing? EDIT (Update 9/1/09): I can now connect to the machine and see the shares on it (see my response to djhowell's answer) but when I try to connect, I get an error saying The network path was not found. I checked the log entry on the Fedora computer for the computer I'm connecting from (/var/log/samba/log.ComputerX) and it reads: [2009/09/01 12:02:46, 1] libads/cldap.c:recv_cldap_netlogon(157) no reply received to cldap netlogon [2009/09/01 12:02:46, 1] libads/ldap.c:ads_find_dc(417) ads_find_dc: failed to find a valid DC on our site (Default-First-Site-Name), trying to find another DC Config files as of 9/1/09: smb.conf: [global] Workgroup = TEST realm = TEST.MYCOMPANY.COM password server = DC.TEST.MYCOMPANY.COM security = DOMAIN server string = Test Samba Server log file = /var/log/samba/log.%m max log size = 50 idmap uid = 15000-20000 idmap gid = 15000-20000 windbind use default domain = yes cups options = raw client use spnego = no server signing = auto client signing = auto [share] comment = Test Share path = /mnt/storage1 valid users = adminuser admin users = adminuser read list = adminuser write list = adminuser read only = No I also set the krb5.conf file to look like this: [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = test.mycompany.com dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h forwardable = yes [realms] TEST.MYCOMPANY.COM = { kdc = dc.test.mycompany.com admin_server = dc.test.mycompany.com default_domain = test.mycompany.com } [domain_realm] dc.test.mycompany.com = test.mycompany.com .dc.test.mycompany.com = test.mycompany.com [appdefaults] pam = { debug = false ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false } I realize that there might be an issue with EXAMPLE.COM in there, however if I change it to TEST.MYCOMPANY.COM then it fails to join the domain with a preauthentication failure. As of 9/1/09, this is no longer the case.

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

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

  • How do I migrate Exchange 2007 to new hardware?

    - by Graeme Donaldson
    As per my previous question, I have an Exchange 2007 box which is also a DC. Since I can't demote it while Exchange is installed, I want to move Exchange to a different server. Does anyone have any articles, tips or experiences to share on this? The last time I did this it was with Exchange 2003 and even that is a little rusty in my head. The setup is a single Exchange 2007 Hub/Edge/Mailbox/CAS server. Its currently on Windows Server 2008, I can migrate it to the same OS, or I can go to 2008 R2, I'm not really picky on that. We're running OWA/ActiveSync/POP3(S)/IMAP(S) for client access. I already have another fully functional DC/GC/DNS box in the same site and clients in the site are already using that for DNS. It's also the preferred site bridgehead for AD replication. Update: After reading Evan's answer I realised that my original question wasn't worded correctly. I'm not looking to do a swing migration, I actually need to move Exchange completely over to a new box. I have done swing migrations in the past, i.e. moving over to a temporary box and back to the original hardware afterwards, and I'm not really sure why I used that term in the original question since it's not what I intended. Any tips?

  • cURL - Unkown SSL protocol error - OS X 10.9

    - by saq7
    I am trying to use cURL and get the following error on every https request I make. The error is always the same. HTTP requests work flawlessly. The verbose output is quite useless.

Most people's issues involve particular servers and the configuration of SSL on these servers. Mine however is problematic anytime HTTPS is used (with any website). Can someone please suggest what I should be looking into to solve the problem? Can it be that something is not properly configured? What should I be looking for?

  • Sparing level on HP EVA 4000

    - by Samuel
    One of the disks of our EVA4000 died today. This diskgroup (all volumes vraid5 with sparing level 1 and almost no space left for more volumes, 1TiB drives) is being rebuilt with "spare space" right now, and it will take at least 15 hours to do the leveling/rebuilding. We can't get a new disk until Friday. So, the question is, what would happen if another disk dies before the leveling completes? Would we lose data? And after that, how many aditional disks could die before losing data? 1 or 2? In "usual" RAID, we would be vulnerable to data loss while the rebuild takes place, but in this case the space reserved for sparing is two times the size of the bigger disk, so at the very least the effect should be the same of having two spares. Thanks in advance. Update: I have found some interesting threads about this question but still can't answer to this question, so I'm starting a bounty. http://blog.thestoragearchitect.com/2008/10/27/understanding-eva/ http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&url=http%3A%2F%2Fwww.experts-exchange.com%2FStorage%2FStorage_Technology%2FQ_25548177.html (Expert Exchange question from google).

  • Triple-monitor set-up (2 unique, 1 cloned): Can a VGA splitter be used on one output of a dual-head

    - by stakx
    Background: I'm currently researching hardware components for some kind of information terminal we're building. This application of ours makes use of three output screens: (1) A touch screen where all user input is made; (2) A regular LCD monitor where the requested information is being displayed; and (3) A projector which displays exactly the same signal as screen (2) does. (All screens will run at the same resolution of 1024x768 btw.) Now I figured that using a dual-head video card would be sufficient, let's say a Matrox P690 low-profile PCI card. This would involve having a Y cable connected to the graphics card itself, then two DVI-to-VGA adapters at each end of the Y cable, and then having a VGA splitter on one of the VGA outputs. The following shows the setup in question: 0--1---------2-> VGA (DSUB-15) \ \ ----2-3---------> VGA (DSUB-15) \ \ -----------------> VGA (DSUB-15) 0: graphics card (LFH60 jack) 1: LFH60 to DVI-I dual monitor Y cable 2: DVI-to-VGA adapters 3: VGA splitter cable Question(s): Will this work? I'm particularly concerned about the following points: Can a low-profile PCI video card output a signal which is strong enough for three monitors (even if it's a dual-head card)? Does the combination of so many adapters and splitter cables work? (The LFH-to-DVI cable comes with the video card) Will the VGA splitter cable degrade the signal on the output screen & projector significantly? (If so, would a USB-powered splitter cable remedy this problem?) I can't possibly expect anyone to answer all those questions, but any input is appreciated.

  • Oracle logical standby fails with ORA-01919

    - by DCookie
    I have an Oracle logical standby database being managed via data guard. Just this morning the redo apply process began failing with an ORA-01919 error, indicating one of our application roles did not exist. However, I can see the role on both primary and standby databases. We also have a physical standby that has long since applied the redo where this is happening on the logical, without issue. I have opened an SR with Oracle. I was wondering if anyone out there has seen this before. I guess I should mention: Oracle 10.2.0.4, Win2003 Server SP2. UPDATE: So far, Oracle Support has not provided an answer. I thought I'd post here what I have learned so far. It appears that a grant of DBA on the primary host to a role works fine for users granted the role. It does not work on the logical standby. IOW: create role TEST; grant dba to TEST; grant TEST to auser; connect auser set role TEST; grant <existing role> to <existing user>; This works on the primary instance but fails on the logical. A workaround appears to be to grant each role on the primary to the role TEST with admin option in the logical: grant <existing role> to TEST with admin option; <== do this on the logical standby Then the command works on the logical standby.

  • Cannot properly read files on the local server

    - by Andrew Bestic
    I'm running a RedHat 6.2 Amazon EC2 instance using stock Apache and IUS PHP53u+MySQL (+mbstring, +mysqli, +mcrypt), and phpMyAdmin from git. All configuration is near-vanilla, assuming the described installation procedure. I've been trying to import SQL files into the database using phpMyAdmin to read them from a directory on my server. phpMyAdmin lists the files fine in the drop down, but returns a "File could not be read" error when actually trying to import. Furthermore, when trying to execute file_get_contents(); on the file, it also returns a "failed to open stream: Permission denied" error. In fact, when my brother was attempting to import the SQL files using MySQL "SOURCE" as an authenticated MySQL user with ALL PRIVILEGES, he was getting an error reading the file. It seems that we are unable to read/import these files with ANY method other than root under SSH (although I can't say I've tried every possible method). I have never had this issue under regular CentOS (5, 6, 6.2) installations with the same LAMP stack configuration. Some things I've tried after searching Google and StackExchange: CHMOD 0777 both directory and files, CHOWN root, apache (only two users I can think of that PHP would use), Importing SQL files with total size under both upload_max_filesize and post_max_size, PHP open_basedir commented out, or = "/var/www" (my sites are using Apache VirtualHosts within that directory, and all the SQL files are deep within that directory), PHP safe mode is OFF (it was never ON) At the moment I have solved this issue with the smaller files by using the FILE UPLOAD method directly to phpMyAdmin, but this will not be suitable for uploading my 200+ MiB SQL files as I don't have a stable Internet connection. Any light you could shed on this situation would be greatly appreciated. I'm fair with Linux, and for the things that do stump me, Google usually has an answer. Not this time, though!

  • OpenSolaris livecd, NForce NIC driver, and NTFS USB mounting. Oh My!

    - by Jake Wharton
    I'm attempting to install OpenSolaris 2009.06 on my server. Before I do I would like to test that everything works and am running in to problems. It has an Abit AN-M2 motherboard with an NForce chipset. The driver config utility says that I need a third-party driver and links me to http://homepage2.nifty.com/mrym3/taiyodo/eng/. Scrolling to the bottom, I have downloaded both tgzs just in case. Now the fun part: The only way to get this on to the computer is via a USB drive since I can't access the network. Also, install CD in the drive otherwise I'd just burn them to DVD. Since my USB key is NTFS formatted I cannot mount it since the install CD seems to be lacking NTFS drivers which require more downloaded packages. What should I do? The server will simply be a dumb NAS and I know that there exists other OpenSolaris-based flavors such as Nexenta but from what I read the stock install is likely the best. If this is not the case and pursuing a different flavor is required or better I will also accept that as an answer (but please don't jump straight to it).

  • Why cache static files with Varnish, why not pass

    - by Saif Bechan
    I have a system runnning nginx / php-fpm / varnish / wordpress and amazon s3. Now I have looked at a lot of configuration files while setting up the system, and in all of them I found something like this: /* If the request is for pictures, javascript, css, etc */ if (req.url ~ "\.(jpg|jpeg|png|gif|css|js)$") { /* Remove the cookie and make the request static */ unset req.http.cookie; return (lookup); } I do not understand why this is done. Most of the examples also run NginX as a webserver. Now the question is, why would you use the varnish cache to cache these static files. It makes much more sense to me to only cache the dynamic files so that php-fpm / mysql don't get hit that much. Am I correct or am I missing something here? UPDATE I want to add some info to the question based on the answer given. If you have a dynamic website, where the content actually changes a lot, chaching does not make sense. But if you use WordPress for a static website for example, this can be cached for long periods of time. That said, more important to me is static conent. I have found a link with some test and benchmarks on different cache apps and webserver apps. http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/ NginX is actually faster in getting your static content, so it makes more sense to just let it pass. NginX works great with static files. -- Apart from that, most of the time static content is not even in the webserver itself. Most of the time this content is stores on a CDN somewhere, maybe AWS S3, something like that. I think the varnish cache is the last place where you want to have you static content stored.

  • Home Sharing and Remote on iTunes causing firewall nags

    - by BoltClock
    It seems that enabling Home Sharing and/or hooking up my iPhone's Remote to iTunes causes Mac OS X Snow Leopard's firewall to freak out and keep nagging every time I launch iTunes to ask if I'd like it to accept incoming connections. If I turn off Home Sharing and forget all Remotes, the nag dialog no longer comes up. I could also disable the firewall, but I think that's a silly thing to do. iTunes is already in the firewall whitelist, so the only thing I know that could cause Mac OS X to nag is a bad application bundle code signature. I checked with this Terminal command: $ codesign -vvv /Applications/iTunes.app/ And sure enough, this is what it outputs: /Applications/iTunes.app/: a sealed resource is missing or invalid /Applications/iTunes.app/Contents/Resources/English.lproj/AutofillSettings.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/iTunesDJSettings.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/MobilePhonePrefs.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/MobilePhoneSetup.nib/objects.xib: resource added /Applications/iTunes.app/Contents/Resources/English.lproj/UniversalAccess.nib/objects.xib: resource added I've tried reinstalling iTunes as suggested by this answer, but Mac OS X still nags about incoming connections and the exact same output is generated when I run the above command again. On my PC, Windows Firewall has never nagged whenever I turn on Home Sharing and hook up Remote on my iPhone. Both computers use iTunes 9.2.1. My Mac runs Mac OS X 10.6.4. Is there anything special I need to do that I might have missed? Or how do I resolve the issue? EDIT: I've updated to iTunes 10, but the nags on my Mac are still there and only go away if I turn off Home Sharing and Remote. EDIT 2: I've updated to Remote 2.0 on my iPhone, but the firewall nags are persisting. Has anyone else had this firewall issue at all?

  • IP-dependent local port-forwarding on Linux

    - by chronos
    I have configured my server's sshd to listen on a non-standard port 42. However, at work I am behind a firewall/proxy, which only allow outgoing connections to ports 21, 22, 80 and 443. Consequently, I cannot ssh to my server from work, which is bad. I do not want to return sshd to port 22. The idea is this: on my server, locally forward port 22 to port 42 if source IP is matching the external IP of my work's network. For clarity, let us assume that my server's IP is 169.1.1.1 (on eth1), and my work external IP is 169.250.250.250. For all IPs different from 169.250.250.250, my server should respond with an expected 'connection refused', as it does for a non-listening port. I'm very new to iptables. I have briefly looked through the long iptables manual and these related / relevant questions: http://serverfault.com/questions/57872/iptables-question-forwarding-port-x-to-an-ssh-port-of-different-machine-on-the-n http://serverfault.com/questions/140622/how-can-i-port-forward-with-iptables However, those questions deal with more complicated several-host scenarios, and it is not clear to me which tables and chains I should use for local port-forwarding, and if I should have 2 rules (for "question" and "answer" packets), or only 1 rule for "question" packets. So far I have only enabled forwarding via sysctl. I will start testing solutions tomorrow, and will appreciate pointers or maybe case-specific examples for implementing my simple scenario. Is the draft solution below correct? iptables -A INPUT [-m state] [-i eth1] --source 169.250.250.250 -p tcp --destination 169.1.1.1:42 --dport 22 --state NEW,ESTABLISHED,RELATED -j ACCEPT Should I use the mangle table instead of filter? And/or FORWARD chain instead of INPUT?

  • How does the Windows RENAME command interpret wildcards?

    - by dbenham
    How does the Windows RENAME (REN) command interpret wildcards? The built in HELP facility is of no help - it doesn't address wildcards at all. The Microsoft technet XP online help isn't much better. Here is all it has to say regarding wildcards: "You can use wildcards (* and ?) in either file name parameter. If you use wildcards in filename2, the characters represented by the wildcards will be identical to the corresponding characters in filename1." Not much help - there are many ways that statement can be interpretted. I've managed to successfully use wildcards in the filename2 parameter on some occasions, but it has always been trial and error. I haven't been able to anticipate what works and what doesn't. Frequently I've had to resort to writing a small batch script with a FOR loop that parses each name so that I can build each new name as needed. Not very convenient. If I knew the rules for how wildcards are processed then I figure I could use the RENAME command more effectively without having to resort to batch as often. Of course knowing the rules would also benefit batch development. (Yes - this is a case where I am posting a paired question and answer. I got tired of not knowing the rules and decided to experiment on my own. I figure many others may be interested in what I discovered)

  • CloneZilla Broke My System? Ubunut Installation Lost After Running CloneZilla

    - by nicorellius
    I just read through this post and tried to get my installation back using this answer to no avail. What happened to me is this: I spent an hour or more reading through the CloneZilla docs. I thought I was ready to test it out so I burned the disc with the ISO image on it and ran it. The system I used was Ubuntu 10.04, 32-bit. Everything seemed to go fine. I made a clone of my first partition and copied it to my second partition. I followed the instructions, removed the disc and rebooted my system. At this point, I would expect to have two bootable Linux installations, identical to one another. However, upon booting, I got this error message: error: no such device: 4cf1a6ef-xxxx-xxxx-xxxx-4e3a3ce92bcd error: file not found I booted from a Live Ubuntu disc and was able to see my to partitions: 4cf1(1) and 4cf1(2) (abbreviated, because the volumes have long numbers to identify them). The 50 GB partition, on which the original Ubuntu installation sits is the number and the second partition (175 GB) is the same number with an "_" at the end. I could browse the disc partitions and see the files, but I'm not sure what to do next. I know there is a way to restore my grub loader and actually boot either of these installations, but my Linux know-how is limited. Can I edit the boot loader file to fix this problem? The only clue I have is CloneZilla said something about making a new GRUB but I thought it was going to basically modify it so I could boot either installation. Not sure what happened. I am going to look through this post for the time being to see if I can learn anything to help my problem. But I thought that, since this happened as a result of using CloneZilla, it may be a unique question for this board.

  • IP Phone over VPN - one way calls unless default route?

    - by dannymcc
    I have come across a strange problem with our VPN and BCM 50 (Nortel/Avaya) phone system. As you can tell by my other questions I have been doing some work on setting a VPN up from one location to another and it's all working well. With one exception. We have an IP phone that is connected at the remote location, straight to a router which has a VPN tunnel to our main practice. The phone works mostly, but every few calls it turns into a one way call. As in, the caller (from the remote phone) can't hear the receiver- but the receiver can hear the caller. This is fixed by setting the VPN tunnel to be the default route for all traffic. The problem with fixing it that way is that all traffic then goes through the tunnel which slows internet access etc. down considerably. The router is set to send the following over the VPN: 192.168.1.0/24 192.168.2.0/24 192.168.4.0/24 The IP of the remote location is: 192.168.3.0/24 The remote router (where the phone is) is a Draytek 2830n, and the local router (at the main practice) is a Draytek 2820. We are using an IPSec tunnel with AES encryption <- as a result of a previous answer pointing to the incompatibility in the hardware encryption. Any advice would be appreciated!

  • Monospace font which supports at least both of Korean hangul and the Georgian alphabet?

    - by hippietrail
    Being both a language enthusiast and a programmer, I find myself often doing programming or text processing involving foreign language alphabets and scripts. One annoyance however is that CJK fonts (those which support Chinese, Japanese, and/or Korean) usually only contain glyphs for Latin, Greek, and Cyrillic at best. Often the Asian glyphs will be beautiful but the other glyphs can be quite ugly. Just as often in text editors you can only choose a single font, not one for CJKV and one for other, which will be each used for rendering the appropriate characters. Korean is one of the languages I'm most interested in currently. I only need hangul / hangeul for monospaced editing, hanja isn't common enough to be a problem. Another of the languages I'm currently involved in is Georgian, which has its own alphabet which is a little exotic but has pretty good support in common fonts on Windows and *nix. But I am as yet unable to find a font with good Korean glyphs and also Georgian glyphs. My editor of choice is gVim, so an answer telling me how to set it to use two fonts together would be just as good. Currently I'm using it mostly under Windows 7 so a vim-specific solution would be needed rather than a *nix-specific solution.
