cinelerra & libstdc++so.3

Well, i installed the SuSe 8.2 pro, and it's really nice. Found Kino and got my firewire DV video camera to download some AVI files. wow! To get a final product SVCD of my little princess riding horses, i decided to use Cinelerra.it won't install, because libstdc++so.3 isn't found. I have all the C++ from SuSe, but, not this.

My Questions: 1 i have the files from a Linux Format DVD "essentials" section. It looks "involved" to install. Do i need the one file libstdc++so.3, or the whole group?

2 Could you recommend a course of action. I would like to do some video editing again. I'm 1/2 way there and real excited. Dang! i'm getting all shaky again!

This looks like a classic case of "I cannot find the symlink". I usually get annoyed at programs that do this, but the solution is simple:

1. Find "libstdc++" (possibly in /usr/lib/)

2. ln -s /usr/lib/libstdc++ /usr/lib/libstdc++so.3

(What you may find is that a file called "libstdc++so.so" exists, and should that point of a library file, symlink it as appropriate).

3. run "ldconfig -X" (as root)

(Step 3 is there to keep the cache happy, although it is usually not needed).

HTH,

Thank you very much. Cinelerra is working, the frame rate is up w/ my NVIDIA driver, and i have 2 week's vacation starting today!. whoo hoo!

I am requesting your permission to post your suggestion to the web - chat sites where a few are experiencing similar difficulties.

thanks a 1 EE6.

problem in dns setting up

Hi, We have leaseline from our isp and they have given us 8 ethernet ipz(public ip) for our internal servers. The problem is that our ispz dns doesnt work properly. so i thought of setting up my own dns.

I was able to setup the dns on the private

network(192.168.1.1-first ethernet card) successfully but was not able to setup the dns properly on the public ip(another ethernet card). What wud be reverse lookup zone file in the case of public ip?(I was given by my isp only 8 pulic ipz ). Anticipating ur reply

[Kapil] This can only be done by subnet assignment. The ISP needs to create entries for your in their reverse zone file which point to your server. Look for CIDR or Classless Internet Domain Routing on google.

I think this is only applicable if bot hyou and the ISP use "bind". If you use DJBernstein's domain name server programs then things are different.

To repeat, this is only possible through co-operation with the entity (presumably your ISP) who has been authorised to provide reverse lookup to the entire Class C net to which your eight addresses belong.

As an example you can get for our domain:

$ host -t PTR 81.209.199.203.in-addr.arpa.
81.209.199.203.in-addr.arpa     CNAME   81.imsc.209.199.203.in-addr.arpa
81.imsc.209.199.203.in-addr.arpa        PTR     proxy.imsc.res.in

$ host -t NS 209.199.203.in-addr.arpa.
209.199.203.in-addr.arpa        NS      md3.vsnl.net.in
209.199.203.in-addr.arpa        NS      md2.vsnl.net.in

$ host -t NS imsc.209.199.203.in-addr.arpa.
imsc.209.199.203.in-addr.arpa   NS      ns1.imsc.res.in
imsc.209.199.203.in-addr.arpa   NS      ns2.imsc.res.in

Home LAN setup question

Hi there dude,

i have a general question regarding Home LAN setup on Linux

I have 2 PCs to be networked and sharing a connection. Do i need 2 network cards, 1 leading out to the outside world, another leading to my internal LAN? Is this setup common? Will it help in LAN security?

Thanks a mil

[Faber] These days, the Dude has been upgraded to Dudes and a Dudette. We're now known as The Answer Gang. The Answer Guy is still around , but he's got help these days.

Generally speaking, if you're using one of the Linux boxes as a router/firewall. If you're using, say a LInksys router/firewall, then no, you don't need two NICS in one Linux box.

Check out www.tldp.org for various documents on setting up networks and routers using Linux.

Anyone for winRAID?

[hugo] I seem to be getting a small but steady flow of people
[hugo] asking me about the Adaptec Serial ATA RAID card and Linux.
[editorgal] hrmmmm
[editorgal] is there a distro being buggy about it?
[hugo] No, it just doesn't work right.
[editorgal] a pal tells me that aacraid code is busted in some of the gentoo kernel kits but is safe to use in their vanilla source kit
[hugo] It's not AAC at all.
[hugo] It's the AAR-1210SA.
[editorgal] is theer a secret handshake for it or is it just Being Evil right now?
[hugo] It's based on the SiI3112 chip, but Adaptec mangled it.
[hugo] You can write stuff to the disk drive and read it back again,
[editorgal] since I'm working on the tips section anyway....
[hugo] but every disk access just causes a DMA timeout,
[editorgal] ouch
[hugo] which takes anything up to about 45 seconds to clear.
[editorgal] urgh
[hugo] So it's basically worthless.
[editorgal] that's millenia in computer time
[hugo] I wrote a patch to the kernel to recognise the PCI ID of the card,
[hugo] which works (I've got code in the kernel! Woohoo!)
[hugo] but it has the unfortunate effect above.
[editorgal] this a private patch or submitted?
[hugo] Submitted.
[hugo] It went in 2.4.21-ac1, and 2.4.22 I think.
[hugo] (Or was it 2.4.20-ac1 and 2.4.21? I can't remember)
[editorgal] ok, it wasn't handled at all, but you provided code which tries to handle it, only DMA is still wicked?
[hugo] Yes, that's about the size of it.
[hugo] Adaptec provide Linux drivers for the card,
[hugo] but they're only for certain stock Red Hat kernel packages.
[hugo] and they're binary-only.
* Editorgal avoids ranting about RH's concept of "stock"
[hugo] I've tried asking moderately noisily on LKML about the problems with this card,
[hugo] but nobody seems to be able to give me any information at all.
[hugo] All I've achieved is having several email threads archived where I appear to be
[hugo] the font of all knowledge about getting the 1210SA working under Linux.
[tonytiger] heh
[hugo] As soon as this month's pay cheque clears, I'm buying an SIIG card instead,
[hugo] and selling the Adaptec on eBay.
[editorgal] what's the info you want to get, I could post a wanted note for you in LG?
[hugo] Why isn't it working, and how do you fix it?
[hugo] TBH, I can't be arsed at this point.
[editorgal] it isn't working because adaptec's too lame to cough up a source module instead of a binary for RH's heavily mangled kernels.
[hugo] Well, yes, that's about the size of it.
* Editorgal captures this thread for the 2c Tips column
[hugo] Also, I think they want to hide the fact that the RAID (0, 1, 0+1) part of the card is effectively done in software.
[hugo] (Or so it is rumoured)

That "rumor" is per a Linux Kernel Mailing List (LKML) post by Sam Flory. It's probably mirrored lots of places, but here's a pointer:
https://marc.theaimsgroup.com/?l=linux-kernel&m=105484662322837&w=2
In the rest of the thread, Hugo notes that he's only looking for basic drive-access features, but above, he notes that he hasn't managed to code them up himself, and is giving up (his main contribution having been patching the PCI ID recognition). For fairness sake they have binary modules for a few other stock boxed-linux kernels but as soon as you stray off the beaten path - and possibly as soon as you upgrade even if staying within the distro's offered kernels - someone else will have to figure out why the SiI3112 chip hates Seagate SATA drives.
