php anyone?

Can anyone help me with a bit of php? I need to append the copntents of one file on to another when a web page is accessed. Cron is no use as the timing isn't fixed. I can append a line of text so far, but not the contents of a file, and as I'm away for the rest of the week and have been doing this manually till I find the fix, I'm panicking! - - help! Cheers, Jenny.

This is still causing problems. Anytime I try and gain information about this samba-mounted share, (including the fuser or umount commands) I simply get "Input/output error". I wondered if the fault lies in me changing the share to "full share" from "read only" from the windows side of things,while it was still mounted. (Changing it back doesn't make a difference).

I'm only a young whippersnapper(17), and learnt how to use a computer with a 386 dx 44(Which is still around somewhere with Doom2 yeah!).and Win 3.1 when I was 11. As my dad has been in the computer world for 25+ years he had been using Linux since 0.9X (with a smug smile as well) He always used to tell me that MS was really a load of poopoo. I upgraded computer and os to MS win 95. Then I dicovered the joys of Linux. The one thing that attracted me to linux was The Gimp. My first linux distro was Redhat 6.2 Ahhh the memories; trying desperatly to compile some game or other and wondering what the hell this make and make install buisness was about. one other thing that stick out in my mind is my dad showing me this thing called the world wide web, This must have been when I was about nine/ten. Ahh the halowed sounds of a 14.4k modem :) PS Who is the youngest person on this list?

BJ asked: > How can I get the alt property within an <img src=...> to be pre formatted > or at least can I get line breaks in it? If the browser doesn't wrap the alt contents, then it's a bug in the browser interface, IMO. You can either try using literal breaks or just hope the browser wraps intelligently, but I know of browsers which do neither. Sorry I can't answer the SGML one off the top of my head, but surely the web contains the answer for the particular DTD you're using? I can't think of any way of inlining images, at least. Here's a related question to both of them: when sending an xhtml attachment to an email, and attaching referenced images, how do you refer to them from the xhtml part? Just curious. It's not something I make a habit of trying to do, but it would be nice to know how to do it from GNU/Linux. -- MJR

Thanks, Steve....that makes sense. However I can't unmount as it thinks the share is busy, and I did restart the windows - is there any way i can manually flush the names on the internal cache?

[Thinks, what am I doing in at work on a lovely saturday....] Can anyone help me on this?......I mounted a shared directory on my windows machine onto a directory called /jenshare on my linuxbox using smbmount. Then i went home, switched off the windows machine and forgot all about it. Now I have an error coming up right left and centre "File 'jenshare' exists but can not be stat-ed: Input/output error" Doing a ls-l / doesn't show the directory jenshare (I/O error again), however ls -a / does show it.

My first installation was RdHat6.2 on a laptop, I then built a computer from old cast-off bits from work and put RedHat6.2 on that. That was in autumn 2000. Late 2001 saw me installing debian on another old unwanted box at work, I then installed it on the box at home, and then the laptop. As I type I am installing a more recent version of debian onto a brand new box fresh in from the shop. When I installed on the box I built myself with old cronky hardware, it took me months to get anything going. This install here it is all "just working". Still, it is good to learn the hard way. I'm also running experiments on a hacked-about kernel running on an ipaq http://www.toby-churchill.org Jen.

Kernel compile/W00t! was RE:NVIDIA/X
by Ricardo Campos 16 Feb '02

16 Feb '02

ThankyouThankyouThankyouThankyou! Just compiled my first kernel from source (2.4.17), and- wow! That was scarily easy! THEN I compiled the NVIDIA kernel& GLX from source. Weeeeeeeeeeee! Hurrah for openGL! Any other newbies out there- follow the instructions in the HOWTO's and voila (helps if you use LILO as most docs are on that)! Anyways, only two probs: 1 module won't load, I'll see to that when it becomes a problem. The second one, though, is that it won't automatically mount hda8 (I can do it from BASH), because it says I have too many filesystems. Checking /etc/fstab I appear to have 2 swap files (oops, I mean *partitions*) mounted??????? Eh??? I didn't put that there! Any idea how it might have got there? I'm removing it, so only the correct one is present. Just bugs me how it got there.

SFPack & Soundfonts in Linux
by Edenyard 15 Feb '02

15 Feb '02

Here's a tricky one! I've managed to get ALSA and Timidity working quite nicely on my Linux box, despite its being only an ex-skip P166. Now I want to load a particular set of sound fonts. I've already got the usual GUS and Midia sets and now I've downloaded two sets that I particularly want. They're both packed in some format called SFPack, which seems to be a windoze type of format. I've searched around on Google but I haven't located anything that seems to come remotely close to SFPack that runs on Linux. Since I don't have windoze, I'm stuck. This is highly frustrating. Please does anyone have any ideas? Gerald.

pcmcia and laptop issue
by Jenny_Hopkins＠toby-churchill.com 15 Feb '02

15 Feb '02

Hello All, just a thanks to all who have helped with my laptop and the pc card not working thing. A brief history for those not at the last meeting: This laptop originally had on RH6.2, the pc card (buffalo) wouldn't work at all. Then I installed debian with a 2.2.18pre21 kernel, and it half worked, but the interrupts kept being dropped and it was very humpty. At the last meeting we installed a new kernel (2.2.4 I think but not having the laptop here I can't check, or was it 2.4 something? I really ought to know these things but life is too short to know *everything*!) but then discovered this particular kernel handles pcmcia differently and it has to be loaded as a separate module. So last night I downloaded pcmcia.cs latest version onto a floppy, copied to laptop, configured and ran make, and hey presto! it works beautifully. Cheers, Jenny.

NVIDIA/ X
by Ricardo Campos 15 Feb '02

15 Feb '02

> Why would you want to play Q3 anyway? ;-) Rune and Tux Racer, actually! :-P, the driver provided by X is WELL below par (in fact unusable) for openGL games. HOWEVER, I now want it back, at least it damn well worked! :'( > No, the problem is that when they fry the system, you can't debug it. The > cause is that they are needlessly restricted. I get Mark's point, though. It would be a much better idea if NVIDIA left it open for the XFree86/kernel hackers to work on, cos they seem to have a better idea of what they're doing. Sorry to selfishly steer towards my problem. I still have a seriously fscked X configuration (i.e. it don't work), with no NVdriver module anywhere. So... this module- part of X or part of the kernel? Does the kernel load this module, which is provided by X, or vice versa? I think I'm getting confuZed here. Am I gonna have to install a kernel from source whether I like it or not now, to get the module back? OR X? How could I find the headers for my existing kernel, if they're not where they're meant to be, so I can rebuild the NVIDIA kernel patch from source?

Sometimes the answer is so simple you just don't see it! Would this *just* provide fault tolerance (if one card goes down, it gives the next IP)? i.e. not load balance. Or does it alternate which IP it gives out to the client issuing the request?

OK. So I decided to test this.... I used the 'which package to use' program from Nvidia. Backed up XF86Config and XF86Config-4. I downloaded the .rpms, and installed them as root in runlevel 4 (5 starts up X). I got an error with the kernel rpm: modprobe can't find NVdriver. find / | grep NVdriver can't find it either. Where did it go? :'( I rebooted to runlevel 4 again just incase. (5 starts x it's a RH7.2 machine). I run startx . Well, all I can say is... thank fsck for ext3! I fiddled with my XF86Config-4 file and managed to get it so it doesn't lock up, but it exits saying it can't find the NVdriver module still. So I downloaded the source tars. I run a make on the kernel modules. It can't find the headers! I boot into my trusty MDK8.0 system, get online, look up every FAQ I can find and some NVIDIA walkthroughs on linuxnewbie.I need to add (apparently) SYSINCLUDE=/lib/modules/2.4.9-21/build/include Only.... there's no such path. It stops at /lib/modules/2.4.9-21/ and the contents DOES have something called BUILD in it, that is flashing for some reason. I *did* recently update the kernel due to the myriad of security errata, but I made sure I downloaded the kernel-headers package too. erm.... *eep*! >all you have to do when you rebuild the > machine is make sure your new user account has the same UID no. or you can > use the chown command as root to get access back to the files when you > have rebuilt the machine.

recovery from disaster/rebuilding kernel
by Ricardo Campos 14 Feb '02

14 Feb '02

I am going to attempt to rebuild my kernel (gulp). Now, if I TOTALLY screw it up (likely), I want to know if it is possible for me to preserve my /home partition, and my X configuration: 1. Will the new kernel build impact on my X configuration? I know that my kernel has the NVdriver module installed (the one that came with X 4.1.0), but I'm concerned as to whether if I rebuild the kernel from source, it will require a new installation of X? 2. I have a separate /home partition, on a separate drive (hdb) to where / resides (hda). I did this incase hda fails.However, as I understand it, even if I make a user with the same name and password and mount /home to the old /home partition, I will still not be able to access any of the files due to permissions- am I right? If so, would there be a way to save the user info on floppy/CD whatever so that if I did fsck it all up, I could just start an install from scratch and use those files to get access to the old /home? (an install from scratch being far quicker!) Could I possibly ask any more questions in one e-mail? ;) TIA Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze

Multiple NICs
by Ricardo Campos 14 Feb '02

14 Feb '02

OK, I'm wondering if this is possible in Linux: One server, thebeast.mydomain.com , has 2 NICS. 1 has an IP of 10.0.0.1, the other of 10.0.0.2 . It is connected to a switch (which has a few other servers attached), and the switch to the rest of the LAN. It's a pretty critical server, under quite heavy load. Is there any way that a client could connect to thebeast.mydomain.com and sometimes connect to one IP, sometimes to another? I'm looking for fault tolerance as well as load balancing between the network cards. I know that Intel Server adapters do this on NT and Novell. Anyone have any ideas? Would it involve DNS jiiggerypokery? i.e. DNS server sending requests to 1 IP then another. Or maybe a switch that could do it? Ricardo PS please don't say "buy another server and cluster it" or somesuch. an additional NIC is FAR cheaper than another high-end server. -- Get your free email from www.linuxmail.org Powered by Outblaze

Thanks, Eric, that worked a treat. I'm a shade embarrassed I didn't spot that functionality myself!
