• EC2 AMI won't boot after edit

  - by Eric Lars0n

  I did something stupid, I got a new laptop and copied everything over to the new one, then wiped the old one clean. Then I realized that I forgot to copy the private key out of .ssh that I use to connect to my AWS EBS backed instance. So I can't log in to my custom AMI. So I created a new Volume from the Snapshot of the AMI, then started up a public instance and attached the Volume to it, edit the sshd_config to allow for password log in. Unmounted the volume, detached it, made a snapshot of it, then made a new AMI from the snapshot. The new AMI launches, but never passes the Status Checks and is not reachable. What am I doing wrong? Or alternatively how can I fix my problem? Edit: Adding some of the console output Linux version 2.6.16-xenU ([email protected]) (gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)) #1 SMP Mon May 28 03:41:49 SAST 2007 BIOS-provided physical RAM map: Xen: 0000000000000000 - 000000006a400000 (usable) 980MB HIGHMEM available. 727MB LOWMEM available.

• Thunderbird is unable to find server in DHCP controlled network.

  - by Skizz

  I have a network which consists of linux server and a combination of WinXP, Win7 and linux clients. All the systems are given dynamic IP addresses by the router which connects them all together. The server hosts an IMAP mail server. On Win7 and WinXP Thunderbird can access the IMAP server without any problems. On the linux client, using the same IMAP parameters, Thunderbird is unable to connect to the server. How do I get Thunderbird to find the server? I'm not sure if this is a linux system configuration problem or a Thunderbird issue. Additional note: The linux client is running Gnome, the server has a series of Samba shares defined. In the client, doing Places-Connect to Server and selecting Windows Share and specifying the server name, the Samba share is mounted OK.

• Have Free website Hosting with Google App Engine

  - by mickthompson

  I'm reading about Google App Engine. I'm creating a bunch of simple dynamic websites in java. I'm considering to use Google App Engine and setup my clients' website on it. In this way I've only to register a domain www.myclietdomain.com and then point that to the GoogleAppEngine application... In this way I plan to avoid hosting costs. Infact I'm paying even for hosting few static html pages... Do you think that is possible to use Google App Engine for this scope?

• How to setup RAID 1 with Intel RST on an existing Windows 7 system?

  - by instcode

  I'd like to setup RAID-1 using Intel Rapid Storage Technology on my Windows 7 64-bit system. I have an 1TB SATA HDD with Windows 7 system installed on the first primary partition (leftmost, ~200GB). The rest of this HDD is unallocated (~800GB). I bought another 2TB SATA, then created a primary partition (leftmost, ~500GB) and filled my data in. The rest of this HDD is unallocated (~1.5TB). A quick disk layout (XXX is the unallocated region): HDD1 (1TB): [ 200GB C:\ SYSTEM | XXXXXXXXXXXX ] HDD2 (2TB): [ 500GB Z:\ PROGRAM | XXXXXXXXXXXXXXXXXXXXXX ] Now, I want to create a 500GB RAID-1 partition (I'm not sure if using "partition" is correct here) on the rightmost of the 2 HDDs above without losing any existing data from both disks. Here is the expected layout: HDD1 (1TB): [ 200GB C:\ SYSTEM | XXXXXX | 500GB D:\ DATA - RAID-1 ] HDD2 (2TB): [ 500GB Z:\ PROGRAM | XXXXXXXXXXXXXXXX | 500GB D:\ DATA RAID-1] Let's not concern about data lost, is it possible to have that final layout using Intel RST? Previously, I tried this layout using dynamic disk & software RAID from Windows and it worked as expected, however, it's quite ugly in resynching after an OS failure that I don't want. If yes, is there a way to keep the data on existing partitions untouched or, at least, it should keep the SYSTEM partition safe (I'm okay if the PROGRAM partition has to be gone.)? Well, are there any strict/special steps I should follow when using the Intel RST manager in order to achieve that? If none of those questions above are "Yes", could you please suggest some other possible layouts that leave the C:SYSTEM partition untouched?

• Two routers, one off-site, same ISP-assigned static IP. A recipe for conflict?

  - by boost

  This is the situation I've inherited: There are two routers, one off-site. Both are connected to the ISP. The ISP assigns both of them the same static IP (or so it seems). Presumably, the network problems we're having are related to the idea that you can't have two instances of the same IP. So we rang up the folk off-site and told them to turn off the router. Now everything's working okay here. How do I get around this? Get another static IP? Figure out how to get the router to ask for a dynamic IP (as we're not using the static IP for anything)?

• How to make a server check it's own availability on the web?

  - by Javawag

  Hi all, Just a quick question – my server is running at my house serving www pages at www.javawag.com. The problem is that my home internet connection keeps dropping randomly - for about 10 mins at a time. This is only an intermittent problem and will go away soon I hope. However, my server doesn't recover properly - when the connection comes back, I can still access it at 192.168.0.8 (locally) without any issue, but at www.javawag.com there's no reply! (Just an aside - my home internet connection is dynamic ISP, the domain www.javawag.com points to javawag.dyndns.org which in turn points to my IP, updated every minute by ddclient on the server) Is there some way for the server to check if it's accessible from the outside world periodically, and if not restart Apache/reboot? Oh, and if I reboot the problem fixes itself also! Javawag

• How do I add a second disk to my zfs root pool

  I am trying to add a new disk to my zfs root pool.

• How to set an executable white list?

  - by izabera

  Under Linux, is it possible to set a white-list of executables for a certain group of users? I need them to be unable to use, for example, make, gcc and executables on removable disks. How can this be done? Edit, let me explain better. I'm dealing with a high school IT system, young geeks that (during the lessons) want to play, surf the net, damage those computer however they can. The major step to achieve this goal was to remove the system they're familiar with and install Ubuntu in all the computers. This actually works quite well, but recent events proved that this is not enough. I want to allow them to execute certain safe programs, like Open Office, and to deny any other program, whether it is preinstalled software, something they carry in usb drives, a downloaded program or a script they program on site. It's possible to remove the 'x' permission on any file on the pc, but of course it would be impractical. Furthermore, they would be able to run anything they download. I thought the best solution would be to make a white-list of safe programs and to deny anything else, but I don't really know how to do it. Any idea is helpful.

• Using DNS entries to determine location

  - by Raphink

  I'm trying to think of a clean way to determine the location of machines (mainly, which datacenter they belong to) based on their network settings. I would like it to be dynamic, and I'm thinking of using special DNS records that would be specific to the DNS server in each datacenter. For example, you could have: root@machine1# dig TXT mysite ... mysite 3600 IN TXT "DC1" ... root@machine2# dig TXT mysite ... mysite 3600 IN TXT "DC2" ... etc. I know that DNS has a special LOC record for location, but it takes coordinates, so it doesn't help in my case. Is there a standard way of addressing this issue, another special type of record for it, or some standard entries in TXT records?

• Use old raid drive as boot device without data loss

  - by Gabriel

  There were two disks in sw-raid. There were /dev/md1 as swap, /dev/md2 as boot and a /dev/md3 with ext4. The sw-raid was disabled by stopping and removing mdadm and then zeroing the superblock on each /dev/mdX partition with: sudo mdadm --zero-superblock /dev/sda1 sudo mdadm --zero-superblock /dev/sda2 sudo mdadm --zero-superblock /dev/sda3 In the disk that is the first boot device, I don't know if it's relevant, the system type of each partition was set back from fd to 82 or 83 with fdisk, /etc/fstab was updated, changing /dev/mdX to /dev/sdaX, and grub was reinstalled on the boot partition (/dev/sda2) with grub-instal. But the system wont boot. What else should I do to use this disk as the boot device without reinstall or data loss? Current output of fdisk Device Boot Start End Blocks Id System /dev/sda1 2048 33556480 16777216+ 82 Linux swap / Solaris /dev/sda2 * 33558528 34607104 524288+ 83 Linux /dev/sda3 34609152 3907027120 1936208984+ 83 Linux With it doesn't boot I mean that it stops in the grub console (with the grub> symbol). A ls command says: (hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos1) It's weird because hd1 was formatted with ext4...

• Decrease in disk performance after partitioning and encryption, is this much of a drop normal?

  - by Biohazard

  I have a server that I only have remote access to. Earlier in the week I repartitioned the 2 disk raid as follows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/sda1_crypt 363G 1.8G 343G 1% / tmpfs 2.0G 0 2.0G 0% /lib/init/rw udev 2.0G 140K 2.0G 1% /dev tmpfs 2.0G 0 2.0G 0% /dev/shm /dev/sda5 461M 26M 412M 6% /boot /dev/sda7 179G 8.6G 162G 6% /data The raid consists of 2 x 300gb SAS 15k disks. Prior to the changes I made, it was being used as a single unencrypted root parition and hdparm -t /dev/sda was giving readings around 240mb/s, which I still get if I do it now: /dev/sda: Timing buffered disk reads: 730 MB in 3.00 seconds = 243.06 MB/sec Since the repartition and encryption, I get the following on the separate partitions: Unencrypted /dev/sda7: /dev/sda7: Timing buffered disk reads: 540 MB in 3.00 seconds = 179.78 MB/sec Unencrypted /dev/sda5: /dev/sda5: Timing buffered disk reads: 476 MB in 2.55 seconds = 186.86 MB/sec Encrypted /dev/mapper/sda1_crypt: /dev/mapper/sda1_crypt: Timing buffered disk reads: 150 MB in 3.03 seconds = 49.54 MB/sec I expected a drop in performance on the encrypted partition, but not that much, but I didn't expect I would get a drop in performance on the other partitions at all. The other hardware in the server is: 2 x Quad Core Intel(R) Xeon(R) CPU E5405 @ 2.00GHz and 4gb RAM $ cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 32 Lun: 00 Vendor: DP Model: BACKPLANE Rev: 1.05 Type: Enclosure ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 00 Lun: 00 Vendor: DELL Model: PERC 6/i Rev: 1.11 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: HL-DT-ST Model: CD-ROM GCR-8240N Rev: 1.10 Type: CD-ROM ANSI SCSI revision: 05 I'm guessing this means the server has a PERC 6/i RAID controller? The encryption was done with default settings during debian 6 installation. I can't recall the exact specifics and am not sure how I go about finding them? Thanks

• Word 2007 "Out of Memory or Disk Space" Error on launch

  - by Adam

  Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

• How to reference individual cells in Excel to variable data from records in an external SQL table

  - by user273476

  I have a SQL table containing date oriented financial data eg. multiple daily records with fields for Date, Account code and Value. I want to set up dynamic links (formulas) from cells in an Excel speadsheet to this data so when the spreadsheet is loaded the data is fetched from all the relevant records. The spreadsheet has the Account codes on the x axis and Dates on the y. Each day the SQL table has new data in it for the new day and I want the spreadsheet to reference this new data for the column for the new day. Any ideas? I have seen how you can generally bring in data from a SQL table (in our case using ODBC as it is not MS SQL) but the data is not simply bringing in multiple records as you would a CVS file but specific records in the SQL table referencing to specific cells and columns in the spreadsheet.

• web spidering/crawling, can i do it or just search engines?

  - by bboyreason

  i already had a question answered about web-scraping with wget. but as i read a little more, i realize i may be looking for a web-crawling program. particularly the part about web-crawlers being able to get specific data like links or, in my case, products. all of the products on my site have the following naming convention, website.com/uniqueAlphaNumericID.html as far as i know, no dynamic content generation is being used and only one page per one item in the above format. should i just be thinking about: wget website.com | grep *.html or should i be looking into spiders/crawlers?

• GRUB reporting wrong partition type

  - by plok

  It all started when I had to replace one of the disks that the software RAID 1 on this machine currently uses. From that moment on I have not been able to boot to the Windows XP that is installed on the fourth hard drive, /dev/sdd. I am almost positive that the problem is related not to Windows but to GRUB, as if I unplug all the other hard drives so that the Windows XP disk is now /dev/sda it boots with no problem. The problem seems to be that GRUB detects a wrong partition type, which I understand suggest that something is really messed up. This is what I get when I try to follow the steps that until now had worked like a charm: grub> map (hd0) (hd3) grub> map (hd3) (hd0) grub> root (hd3,0) Filesystem type is ext2fs, partition type 0xfd 0xfd? That doesn't make sense. /dev/sdb and sdc are 0xfd (Linux raid), but not /dev/sdd: edel:~# fdisk -l [...] Disk /dev/sdd: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00048d89 Device Boot Start End Blocks Id System /dev/sdd1 * 1 30400 244187968+ 7 HPFS/NTFS edel:/boot/grub# cat device.map (hd0) /dev/sda (hd1) /dev/sdb (hd2) /dev/sdc (hd3) /dev/sdd I have been trying to work this out for hours, to no avail. Can anyone point me in the right direction?

• Debian Wheezy (testing) df reported volume size

  I am a bit confused about the /dev/sda* references since I installed Wheezy instead of Squeeze on a testing box. fdisk -l returns: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e9623 Device Boot Start End Blocks Id System /dev/sda1 * 2048 480278527 240138240 83 Linux /dev/sda2 480280574 488396799 4058113 5 Extended /dev/sda5 480280576 488396799 4058112 82 Linux swap / Solaris This seems correct. But df -h /dev/sda (and /dev/sda1 and /dev/sda2 and /dev/sda5) returns: Filesystem Size Used Avail Use% Mounted on udev 10M 0 10M 0% /dev The same happens with every entry under /dev/disk/by-id and /dev/disk/by-path. Only one of two entries under /dev/disk/by-uuid returns the correct volume size: df -h /dev/disk/by-uuid/cacdbad6-7e6b-4e80-84ba-e3c77ef48796 Filesystem Size Used Avail Use% Mounted on /dev/disk/by-uuid/cacdbad6-7e6b-4e80-84ba-e3c77ef48796 229G 22G 196G 11% / Contents of /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

Is this because Wheezy is in testing, and should it be reported as an error?

• 150 TB and growing, but how to grow?

  - by seandavi

  My group currently has two largish storage servers, both NAS running debian linux. The first is an all-in-one 24-disk (SATA) server that is several years old. We have two hardware RAIDS set up on it with LVM over those. The second server is 64 disks divided over 4 enclosures, each a hardware RAID 6, connected via external SAS. We use XFS with LVM over that to create 100TB useable storage. All of this works pretty well, but we are outgrowing these systems. Having build two such servers and still growing, we want to build something that allows us more flexibility in terms of future growth, backup options, that behaves better under disk failure (checking the larger filesystem can take a day or more), and can stand up in a heavily concurrent environment (think small computer cluster). We do not have system administration support, so we administer all of this ourselves (we are a genomics lab). So, what we seek is a relatively low-cost, acceptable performance storage solution that will allow future growth and flexible configuration (think ZFS with different pools having different operating characteristics). We are probably outside the realm of a single NAS. We have been thinking about a combination of ZFS (on openindiana, for example) or btrfs per server with glusterfs running on top of that if we do it ourselves. What we are weighing that against is simply biting the bullet and investing in Isilon or 3Par storage solutions. Any suggestions or experiences are appreciated.

• Combine several locations with regex in nginx

  - by AlexAtNet

  I dynamic number of Joomla installations in subfolders of the domain. For example: http://site/joomla_1/ http://site/joomla_2/ http://site/joomla_3/ ... Currently I have the follwing config that works: index index.php; location / { index index.php index.html index.htm; } location /joomla_1/ { try_files $uri $uri/ /joomla_1/index.php?q=$uri&$args; } location /joomla_2/ { try_files $uri $uri/ /joomla_2/index.php?q=$uri&$args; } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm/joomla.sock; ... } I'm trying to combine joomla_N rules in one: location ~ ^/(joomla_[^/]+)/ { try_files $uri $uri/ /$1/index.php?q=$uri&$args; } but server starts to return index.php as is (does not call the php-fpm). It looks like the nginx stops the processing of the regex rules after the first match. Is there any way to combine this rules with something like regex?

• Reverse Proxy (mod_rewrite) and Rails (absolute paths)

  - by SooDesuNe

  I have front end rails app, that reverse proxies to any of a number of backend rails apps depending on URL, for example http://www.my_host.com/app_one reverse proxies to http://www.remote_host_running_app_one.com such that a URL like http://www.my_host.com/app_one/users will display the contents of http://www.remote_host_running_app_one.com/users I have a large, and ever expanding number of backends, so they can not be explicitly listed anywhere other than a database. This is no problem for mod_rewrite using a prg:/ rewrite map reverse proxy. The question is, the urls returned by rails helpers have the form /controller/action making them absolute to the root. This is a problem for the page served by mod_rewrite because links on the proxied page appear as absolute to the domain. i.e.: http://www.my_host.com/app_one/controller/action has links that end up looking like /controller/action/ when they need to look like /app_one/controller/action mod_proxy_html seems like the right idea, but it doesn't seem to be as dynamic as I would need, since the rules need to be hard coded into the config files. Is there a way to fix this server-side, so that the links will be routed correctly?

• Shortcuts located in "D:\Program Data\..." not working even though they're pointing to the right targets (Windows 7)

  - by Kevin

  I just made a fresh install of my windows 7 home premium using my laptop's recovery disks (HP Pavilion dv6-2151cl) using minimal settings. After install, I set up "Program Data" and "Users" to my D partition to save space changing the folders in the registry. Then I updated windows (including W7 SP1), and installed all other programs. After installing all other programs I noticed that the icons of all new programs (not included in the windows install) in "All Programs" had a blank sheet as icon and they don't do anything. Looked into "D:\Program Data\Microsoft\Windows\Start Menu\Programs" in the windows explorer and the same is true there. All the shortcuts in C: and "D:\Users..." work both in the "Windows Explorer" and "All Programs". Also I noticed that the shortcuts do display the right icons inside the "open" dialog boxes. And if I copy the shortcuts in "D:\Program Data..." to the desktop they also work as expected. I checked file association for .lnk and it was OK, but also tried the registry fixers for this file association and they had no effect. There are no missing programs that I can tell in the "All Programs" menu, the just don't do anything if they lay in "D:\Program Data...". Any thoughts on how to make Windows 7 treat shortcuts in "D:\Program Data..." as they should?

• Why does my simple Raid 1 backup storage perform really slow sometimes?

  - by randomguy

  I bought 2x Samsung F3 EcoGreen 2TB hard disks to make a backup storage. I put them in Raid 1 (mirror) mode. Made a single partition and formatted it to NTFS, running Windows 7. For some reason, accessing the drive's contents (simply by navigating folders) is sometimes really slow. Like opening D:/photos/ can sometimes take several seconds before it starts showing any of the folder's contents. Same applies for other folders. What could be causing this and what could I do to improve the performance? I remember that there was an option somewhere inside Windows to choose fast access but less reliable persistence operations (read/write). It was a tick inside some dialog. At the time, it felt like a good idea to take the tick away from the option and get more reliable persistence but slower access, but now I'm regretting. I'm unable to find this dialog.. I've looked hard. I don't know, if it would make any difference. Oh, and I've ran scan disk and defrag on the drive. No errors and speed isn't improved.

• Computer not finding hard drives on boot -sometimes-

  - by todd.pund

  Computer specs: Mobo: Gigabyte ultradurable 3 - GA-970A-UD3 Processor: First gen I7 3.2GHZ Ram: 8GB Kingston DDR3 1066 Video Card: EVGA NVidia GTX 460 1GB Hard Drive: 500MB 7200rpm x2 (can't remember brand, sorry I'm at work.) Last week my developer preview for Windows 8 ran out so I put my copy of windows 7 back on the computer. The computer at that point started suffering from frequent freezing and crashing. When I rebooted the computer sometimes it wouldn't find the system HD at all. When I looked at the post screen it seemed to show that it wasn't finding either of the HDs. Then yesterday when turning on the computer I just got GRUB as a message (not a GRUB prompt, just GRUB) I haven't had a dual boot of Linux for at least a year. I loaded windows 7 recovery console from the disk and ran: bootrec /fixboot bootrec /fixmbr Which did not help. At that point I just installed Ubuntu 13.04 over the windows 7 install and still received the GRUB post. I went into the BIOS and switched the Hard Drive priorities and then it loaded into Ubuntu fine. For several days everything was just hunky dory until I installed the Ubuntu version of Steam, install Portal and tried to run it. At that point the computer froze and after hard rebooting couldn't find the hard disks again. Then after restarting the system it loaded up fine again and no issues since. (I have not tried to launch portal again). My next thought is to remove the system hard drive and try to use the secondary as the master to see if the primary HD is bad. I'm sorry if this has been confusing, I'll answer any questions I can. Any thoughts?

• Best way to use mod_rewrite to replace WordPress pages with static files

  Here's the situation: I've got an old WordPress installation that I'd like to archive as static files, but I'd also like to preserve old URLs. I've already created the static archive with wget and sorted out the filenames and links. Now I'd like to configure Apache to intercept requests for the old dynamic URL and replace them with the new static one, e.g.: http://www.example.org/log/?p=1234 or http://www.example.org/log/index.php?p=1234 should redirect to http://www.example.org/log/archives/1234.html I've tried adding the following to the VirtualHost config for example.org, but to no effect -- I just get the PHP page. RewriteCond %{REQUEST_URI} /log/ RewriteCond %{QUERY_STRING} p=([^&;]*) RewriteRule ^/$ http://%{SERVER_NAME}/log/archives/%1.html [R,L] I've enabled logging and I can see what look like other rules being applied, but not this one. None of my other guesses at match patterns for %{REQUEST_URI} seem to have any effect either (log, log/, log.*, even .*). I'm new to mod_rewrite and this is mostly cargo cult, so I'm pretty sure I've gotten it wrong. Anyone know what I should be doing here?

• Windows 7 breaks even in safe mode

  - by delenda

  Hi, I have a Dell XPS M1730 with Windows 7 installed. I noticed last night that after a few hours of use, the fans kicked into full and I couldn't do anything without it taking forever. Minimising windows, opening device manager or even opening process explorer took minutes and a game install I had just started took nearly 4 hours to complete. When procexp finally loaded, the refresh was so slow that it was mostly useless. From what I could gather, it was reporting 60% idle processes with procexp using nearly 40%. There were no hardware interrupts listed. When I rebooted, the problem went away for about 10 minutes and then the same thing happened. The issue persists in safe mode and even after I removed the graphics drivers, which have been an issue in the past, it still happens. Icons flash quite quickly on the desktop periodically and screen refresh is painfully slow. When booting now, the fans kick in to full as soon as the windows logon box comes up and it's taking 10 minutes to bring the desktop up. Chkdsk reports nothing and the raid check says that everything is fine. I'm thinking hardware failure, probably HDD but wanted some other opinions. I'm planning to try a linux live cd to see if it works without using the hard disks. If anyone has any input, it would be greatly appreciated. Delenda

• Do I need to recompile PHP to make use of CURL API?

  - by amn

  I have both Apache and PHP set up manually, albeit the latter without CURL. There is this jungle of instructions and explanations on extensions for PHP. I have a very straightforward question - what do I need to do to enable CURL in a more dynamic way. I resent the idea of static linking, in fact I hate and avoid static linking like the plague. Is it possible to have my Apache and PHP understand that there is CURL in town? I can compile CURL if necessary. Package management may be out of the question, because I built PHP myself - I am on Ubuntu, and it does not provide PHP without Suhosin and a a whole lot of time, so I removed it and built PHP myself. The whole slew of related questions simply propse installing "php5-curl" package, which is exactly one thing I CANNOT do since it installs it in a completely unrelated directory, which my PHP does not even seem to bother linking to.
