• Can't use command line – "command not found" after editing PATH

  - by MEM

  I'm running OS X Mavericks and was trying to install MAMP PRO 2.2. I was trying to configure the PATH variable to have the PHP binaries of MAMP PRO. I added the following line on my ~/.bash_profile file: export PATH=/Applications/MAMP PRO/bin/php/php5.5.3/bin:$PATH As you may notice, since I have MAMP PRO and not just MAMP, I've added a space. As a consequence, I know have the following error each time I run the terminal: -bash: export: `PRO/bin/php/php5.5.3/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin': not a valid identifier Worst: I can't get any command to run, like: ls, clear etc. I always get: "command not found" I don't even know the absolute path for ls. How can I make the commands work again, so that I can properly fix the path I was trying to setup on the .bash_profile file?

• compressing dd backup on the fly

  - by Phil

  Maybe this will sound like dumb question but the way i'm trying to do it doesn't work. I'm on livecd, drive is unmounted, etc. When i do backup this way sudo dd if=/dev/sda2 of=/media/disk/sda2-backup-10august09.ext3 bs=64k ...normally it would work but i don't have enough space on external hd i'm copying to (it ALMOST fits into it). So I wanted to compress this way sudo dd if=/dev/sda2 | gzip > /media/disk/sda2-backup-10august09.gz ...but i got permissions denied. I don't understand.

• Transfer Raid Drives to External Enclosure

  - by dubbeat

  I have 2 raid disks (a grand total of 360GB) in my laptop. I'm fast running out of space and want to install new drives. I've a pretty good idea how to do this. My question is what can I do with the drives that I remove? I've got lots of media files on these drives that I'd like to keep and maybe transfer back onto my laptop once I have the new drives installed. Bearing in mind that I know next to nothing about hardware how do you suggegst I go about reusing the removed drives somehow? Thanks,

• What RAID level for a backup server?

  - by ispirto

  I'm building a server with 12 x 3TB disks to use daily backups. I'm thinking to use RAID50 to get a good 27TB usable space. The disks will be used brutally to backup 9 servers with 1.5TB of data once a day. I'll keep the backups for 2 days. So for each server I'll have 3TB of separate partitions. Do you think this kind of huge backups would stress the disks too much and make them fail? Should I better go with RAID10? Oktay

• Reliability of S.M.A.R.T.?

  - by Mark

  I've been using ActiveSmart to monitor my hard-drives health for a few weeks now, and its telling me my brand new 1.5 TB hard-drive is half-dead already. About on-par with one of my hard-drives which I know is at least half dead because I've been having some read errors and heard ticking noises. Now I haven't actually noticed any problems with my 1.5 TB drive; should I be concerned that it's going to crap out on me too? Or could ActiveSmart be giving a mis-diagnosis because I use it a lot or something (I've used up 795 GB in the 2 and a half weeks I've had it). The events that ActiveSmart has been catching is "Hardware ECC recovered". Maybe these new fangled super big hard-drives somehow rely on ECCs to squeeze out the extra space, but this isn't actually a cause for concern?

• Transfer many Gigabytes between two servers

  - by Bernhard

  Hello, I have a big problem. I have to move data from an old Webspace which is only accessibla by ftp. The new root server is accessible by ssh of course :-) I need to move all the data from the old space but the amount is just huge. Is there a way to move all the files directly from the old ftp to the storage and not over a third station (my local machine)? I´ve tried it with ftp but it didn't work. I think I´ve used the wrong commands. Is there a way to do this? Thank you in advance Bernhard

• SQL Server tempdb size seems large, is this normal?

  - by Abe Miessler

  From what I understand the system database is used to hold temporary tables, intermediate results and other temporary information. On one of my database instances I have a tempdb that is seems very large (30GB). This database has not been modified (as in "last modified date" on the mdf file) in over a week. Is it normal to have the temp db remain that large for that long of a period? It seems to me that it should be updating fairly often and returning space that it is using fairly quickly... Am I way off here or is SQL Server doing something weird? FYI: This is a SharePoint 2010 database, not sure if that makes a difference.

• How useful is mounting /tmp noexec?

  - by Novelocrat

  Many people (including the Securing Debian Manual) recommend mounting /tmp with the noexec,nodev,nosuid set of options. This is generally presented as one element of a 'defense-in-depth' strategy, by preventing the escalation of an attack that lets someone write a file, or an attack by a user with a legitimate account but no other writable space. Over time, however, I've encountered arguments (most prominently by Debian/Ubuntu Developer Colin Watson) that noexec is a useless measure, for a couple potential reasons: The user can run /lib/ld-linux.so <binary> in an attempt to get the same effect. The user can still run system-provided interpreters on scripts that can't be run directly Given these arguments, the potential need for more configuration (e.g. debconf likes an executable temporary directory), and the potential loss of convenience, is this a worthwhile security measure? What other holes do you know of that enable circumvention?

• Resize ntfs system partitions with GParted?

  - by ane

  Trying to resize 2 ntfs system and boot partitions (windows 2003 server) using GParted. Goal: Resize D: (/dev/sda1) to ~850G - this is the boot drive with D:\ntldr, boot.ini, etc. Resize C: (/dev/sda5) to 100G - this is the system drive with C:\windows Tried resizing /dev/sda5 first and got the chkdsk error shown in screenshot #2. (You must run chkdsk /f). Have already run chkdsk /f on C: multiple times with no bad sectors or errors found. Have also run multiple chkdsk /f's on the underlying hard disk multiple times and rebooted way more than a couple times with the same error. How do you force gparted to ignore this error and resize? I found there is --force option to ntfsresize but don't know how to get the GParted ISO live CD to use it. How do you move the unallocated space so an extra ~750G is to the right of /dev/sda1 (D:), and an extra 10G to the right of /dev/sda5 (C:)

• Why can I not use the full capacity of my SSD?

  - by bcmcfc

  I am using Paragon to migrate Windows 7 to an SSD. The C drive which should be migrated is a 100GB partition. During the process, Paragon formats the SSD to 80GB. Why doesn't it take the 100 GB? It later fails because it thinks there isn't enough space on the SSD. However the SSD is 11GB bigger than the partition, and only 45GB of the partition were used anyway. How do I get around this? Is there another tool to do the same job which does it better ?

• MySQL Server - Got error -1 from storage engine

  - by Bobby

  I am currently trying to restore a MySQL table from the .ibd file. I have been following the instructions on the MySQL reference manual on how to use DISCARD and IMPORT TABLESPACE to replace the .idb files. Discarding the tablespace returns no error and the file is deleted however IMPORTING the replacement .ibd file yields a "Got error -1 from storage engine" error. There doesn't seem to be too much information about what exactly an error -1 is. Does anybody have any further insight as to why an import table space isn't working?

• Uninstalled Ubuntu, no GRLDR?

  - by user32965

  So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical] I boot up, and get this: Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null Cannot find GRLDR. Press space bar to hold the screen, any other key to boot previous MBR... Timeout: 5 The timeout part just counts down to 0 from 5. I need to turn in this thing before tomorrow, please please please can someone help me out?

• Firefox, Thunderbird, Safari - hangs up on start

  - by takeshin

  I have a strange problem on Windows Vista (Automatic updates). Long time ago I had installed Firefox, Thunderbird, Safari and Opera and they all worked well. Once upon a time, after Windows restart, Firefox, Thunderbird and Safari won't start. [Opera (USB) works fine]. When I start the browser, program name is listed on the processes list, but it is not activated, doesn't show any window. I tried crating new profiles with -ProfileManager, restarting Windows, reinstalling the browsers. I scanned the system for suspected programs and it looks clean. There is 45GB of free HDD space. WTF?

• Can you shrink the sparse disk image of a Mac OS X guest OS in VMWare Fusion?

  - by Paul D. Waite

  I use VMWare Fusion on my Mac to run a virtual Windows 7 machine, and the Microsoft IE compatibility Windows XP virtual machines. In VMWare Tools on the Windows guest OSes, there’s a “Shrink” option that lets you reduce the size of the sparse disk image used by the guest OS, to save hard drive space on your host OX. I’ve recently created another virtual machine, this time running Snow Leopard Server. I was wondering if I could shrink the spare disk image used by this machine too, but I can’t find a VMWare Tools app on the Mac guest OS, even though VMWare Tools have been installed (as VMWare’s Shared Folders feature is working). Is there any way to shrink the sparse disk image used by Mac OS X guest OSes in VMWare Fusion?

• My 4 GB microSD card only allows me to use 1 GB

  - by James Litewski

  My phone came with a 4 GB microSD card. On the card it lists that 3 GB goes to Muve Music which is Cricket's music program, and I get 1 GB... Well, I don't pay for Muve Music, so why waste the space? I thought I'd be able to simply buy an adapter and reformat the microSD card to get the full 4 GB; but that wasn't the case... I could only find the 1 GB partition on the card. I even tried reformatting the disk, but I had no luck. How can I get the full 4 GB? BTW, I'm running Mac OS X v10.7 (Lion).

• Minimal Fedora Installation

  - by MA1

  I am working on a Fedora 13 minimal iso image with no Desktop environment. I just need wxPython support. I removed the gnome from kickstart and build the iso image using livecd-creator. But now my application is not loading as gnome is gone. Earlier my application(myapp.desktop) was placed in /usr/share/gnome/autostart/ and starts automatically. So what should i do now the run my application? To run my wxPython appalication should i have to install display manager(xdm, gdm, kdm etc..)? If i install gdm, it takes lots of space. what should i do? In short i need Fedora 13 minimal iso image with no desktop environment and with wxPython support.

• Why can't I copy a 7 GB file to an external USB HD with 120 GB free?

  - by Johann Gerell

  Yes, why can't I? I was stashing away some old photography backup zips last night. I could copy 4 of my 1 GB backup zips to my external USB connected hard-drive when I got the error message "Cannot copy file. Not enough free space." (sort of) for a zip of roughly 7 GB. But there are 120 GB free. Why is this? EDIT: Clarification - the files that I could copy was smaller than 4 GB. The failing one was 7 GB. The cause seems to be the FAT32 4 GB limit.

• `rsync` NEVER uses its 'famous' delta-transfer!

  - by o_O Tync

  I have a big iso image which is currently being downloaded by a torrent client with space-reservation turned on: that means, file size is not changing while some chunks in in (4 Mib) are constantly changing because of a download. At 90% download I do the initial rsync to save time later: $ rsync -Ph DVD.iso /some/target/ sending incremental file list DVD.iso 2.60G 100% 40.23MB/s 0:01:01 (xfer#1, to-check=0/1) sent 2.60G bytes received 73 bytes 34.59M bytes/sec total size is 2.60G speedup is 1.00 Then, when the file's fully downloaded, I rsync again: total size is 2.60G speedup is 1.00 Speedup=1 says delta-transfer was not used, although 90% of the file has not changed. Why?!

• A button to set all processes to on-hold for Linux?

  - by fuenfundachtzig

  When Linux starts swapping you're basically doomed. Very soon the system won't react to any input any more, but happily swap on until the end of days... Can you think of a command that holds all processes whatsoever, thus (and while) allowing you to open a clean shell where you can examine the source of the problem and kill the process which ate up all the memory? (I guess this won't be easy, because as the memory is probably completely filled up you'd need to swap out some more memory to gather space for opening a shell, on the other hand all other swapping processes must be stopped.) If you tied such a command to a hot key then maybe you can use this as an emergency button saving you a lot a time. Any ideas if this is possible at all? Has somebody tried something like this before? If one could realize this it would be a cool feature :)

• Can I cycle through instances of a style selected via the MS Word styles pane?

  - by Deditos

  Often when I have many co-authors on a MS Word document I find that some of them don't use the styles I've defined for the document, but have achieved similar formatting manually. This results in many styles listed as "in use", each with perhaps only a handful of instances. Word will highlight these instances for me, but then find myself browsing the entire document to check whether they need correcting or are special cases. This can be a particular pain for a long document and when these style fragments occur in the white space between words or paragraphs. Is there a way to cycle through the highlighted instances of a particular style rather than having to hunt for them visually?

• Looking for a good Web Server that is cheap

  - by SoLoGHoST

  I am a Project Manager, and former Lead Developer for a software portal system that requires a forum software to run. I am in need of a server that is cheap, reliable, and supports the latest PHP (5.2+), MySQL, unlimited e-mails (preferably), a cPanel, multiple sub-domains (atleast 3+). Currently I am paying $34.95 USD/month (approx. $420 USD/year). This is too high for me to pay to keep the site running. I just recently became Project Manager and in charge of Finances and I'm extremely concerned for the future of Dream Portal. With those prices I'm not sure I'll be able to keep it running for too long. Can someone please tell me of a good server that meets all of the requirements that I listed above that is cheaper on a yearly basis? Note: Currently on a Dedicated Server with limited disk space at 15000 MB (15 GB), monthly bandwidth = 500000 MB, 50 emails limit, 20 sub-domains limit, 30 FTP accts., and 25 SQL Databases.

• Practical tips when transitioning to xmonad?

  - by meder

  I like the idea and concept of xmonad, however I still keep going back to gnome after an hour or so. This feels like when I first tried to learn vim, but I've gotten past the learning curve point and can't live without vim nowadays. I'm sure the time will come for xmonad too, but I was wondering if current xmonad users can provide transitional tips? FYI, I'm on dual monitors ( 19 inch and 17 inch ). Example of an issue I'm having while in this "transitional" stage: How do you manage keeping the browser and other programs that are most commonly used in full screen mode, since by default I think it opens up in a small tile that takes up a portion of the screen? Do you just shortcut it to make it open full screen, or do you actually not maximize it? Or are there advanced methods through preferences in the conf file, making certain programs take up X space?

• Ad Agency storage/file server +backup needed (NAS or something else?)

  - by Rob

  Looking for a "this is all you need" recommendation. We're a small ad agency with both mac & pcs that access and share files from a 3 yr old Windows 2000 box (no server software). We currently have 1TB on the "server" and back it up to 2 different Seagate Free Agent Pro 1TB external drives. But we're low on space and are looking for something that's bigger, that we can still access from Mac & PC, EASY backup system, secure from viruses, firewall enabled. Not sure if a NAS will work or if we should have a real server. We don't really get on that box except to restore files, or run Norton on it. I hope I've provided enough for a general recommendation. Thanks. Rob Phx

• Why can't my networks reach each other?

  - by HOLOGRAPHICpizza

  We have two Buffalo WZR-HP-G300NH2 routers, with the default firmware, DD-WRT v24SP2-MULTI (10/31/11) std - build 17798. Each has a separate cable internet connection with a public static IP address. They are both in the 24.123.68.0/24 space. Both of them can contact pretty much the whole internet, and they can both be accessed out on the internet with no problem, but for some reason they can't talk to each other! When I try to ping one from the other I always get "Destination Host Unreachable". There are no strange routing or firewall rules in place. And they are both set to respond to pings, I can ping them from outside. Our main IT guy is going to call our ISP on Monday, but I'm impatient, so does anyone have any ideas?
