Can't browse to some sites.
Hi there, At first this sounds real stupid so I apologize. I fail to connect to zap.co.il. other computers (MS) on my network go there with out any problems but another Gentoo (k2.4 and not updated at all) also fails to connect. Didn't notice any other site with similar problems. I tried everything I could. 1. removed all protection definition on the firewall. 2. removed all port forwarding on the firewall. 3. removed all services on my client. 4. changed my IP 5. switched to wireless connection. 6. tried different browsers such as FF, LYNX, IEs for Linux (IE6 on wine), Opera (lynx says: HTTP request sent; waiting for response). 7. tried via different user. 8. telnet zap.co.il 80 9. use older kernel 2.6.20-gentoo-r8. 10. check if I have iptables filtering things.

SCSI Mischif
Hi, I have come across a weird behavior of my SCSI: 1) It tends every once if a while to go offline 2) It tends on reboots (might happen after step 1, but not sure if only after step 1) to switch places, disks that used to be sda are now sdb etc. Anyone seen this? I m running: 2.6.18-4-686 Based on Debian Stable 04:00.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 08) Any other details just ask. -- Noam Rathaus CTO [EMAIL PROTECTED] http://www.beyondsecurity.com Know that you are safe.

gcc thoughts
Hi, list, This letter is probably better suited to hackers-il, but I need help from people that are better acquainted with a development process of gcc. This morning, while browsing through pages of frustratingly irrelevant cscope output, I got an idea. In every kosher *nix development environment, the cross-references (i.e. jump to definition of this struct/function) are built by some crippled 3rd party tool (such as ctags, cscope or home-brewed set of elisp scrips). On the other hand, the only tool that actually knows what is going on during compilation is gcc, so it's only logical that it should build cross-references along the way. It would be simply fantastic. The index would reflect the actual set of #ifdef's I currently work with. It would always point you to the header file that was actually #include-d. It would be immediately useful to almost everyone in FOSS world. I have a couple of ideas, how it might be tailored into gcc running sequence. However, I'm a humble gcc user and I have almost no experience with its inner workings. The idea by itself is so obvious and on-the-surface that it everyone using gcc must come up with it sooner or later. There must be a very sound technical reason not to do so.

At a first stage, it's possible to write an external utility that would take specified map files, reverse the data (i.e. turn a.c defines func1(), func2() into func1() is defined in a.c and func2() is defined in a.c) and build common index.

This way it doesn't really interfere with one-file-at-a-time paradigm, because the map file is a by-product, it's not really passed to the assembler afterwards. A map file would hold only information about this specific .c file (preprocessed, i.e. along with its headers). It would include the information about the file for its external user, such as list of functions defined (name and file:line for every one), non-static variables (name and file:line), etc. How to turn these files into something more useful is a different issue. At a first stage, it's possible to write an external utility that would take specified map files, reverse the data (i.e. turn a.c defines func1(), func2() into func1() is defined in a.c and func2() is defined in a.c) and build common index. Then you would tailor it into makefiles to build project-wide index. The result will still be much better than cscope output, because you will never see header files that were never included (such as wrong architectures and not included code during kernel development). It will also correctly see your current settings of #ifdef's (again, in kernel, it means that it reflects your current .config). Cscope also sometimes fails to parse .c file correctly, such as failing to understand that some specific line is a function declaration if you put line feed between a returned value type and a name. This issue will also be gone -- the index is effectively built by the same semantical analyzer that compiler uses. A disadvantages of this approach are also clear. The data reversing part is error-prone and actually means duplicating part of the functionality of ld, so this part should somehow move to ld. Or maybe not -- for example, duplicate symbols cause ld to fail, but should not be a problem for indexer. It all requires careful design. Tell me if all the above makes any sense. Map file is not created by gcc, it is created by ld that is called by gcc after all files are compiled to object files. So it has nothing to do with the assembler. -- Ori Idan = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

This script builds name file:line table from object/exe file. It is
easy to make tags from this.

Hi, list,
This letter is probably better suited to hackers-il, but I need help
from people that are better acquainted with a development process of gcc.
This morning, while browsing through pages of frustratingly irrelevant
cscope output, I got an idea. In every kosher *nix development
environment, the cross-references (i.e. jump to definition of this
struct/function) are built by some crippled 3rd party tool (such as
ctags, cscope or home-brewed set of elisp scrips). On the other hand,
the only tool that actually knows what is going on during compilation is
gcc, so it's only logical that it should build cross-references along
the way.
It would be simply fantastic. The index would reflect the actual set of
#ifdef's I currently work with. It would always point you to the header
file that was actually #include-d. It would be immediately useful to
almost everyone in FOSS world.
I have a couple of ideas, how it might be tailored into gcc running
sequence. However, I'm a humble gcc user and I have almost no
experience with its inner workings.
The idea by itself is so obvious and on-the-surface that it everyone
using gcc must come up with it sooner or later. There must be a very
sound technical reason not to do so. What is it?

Re: SCSI Mischif
Hi, I have many customers with similar kinds of SCSI controllers running mostly RHEL4 (though many are running RHEL3 5, and a very small part of them non-enterprise Linuxes) and never experienced such a problem. I do not believe that this is a driver issue, and this only leads me to suspect that this is an hardware problem. Actually, if you'll purchase a branded server (Sun, IBM, etc.), no one will blame the Linux. But, you might be facing support issues because of the uncertified untested Linux flavor. (And I wouldn't blame them, I did encounter a few problems in the past which involved specific community Linux releases and branded hardware) - Noam On Jan 15, 2008 9:24 PM, Noam Rathaus [EMAIL PROTECTED] wrote: Hi, Hrm, before I go and start my service agreement that usually results in a eyebrow raising on THIS IS LINUX!

Re: SCSI Mischif
1. the order of assigning a SCSI Device file to a SCSI device, is the order of discovery. for example: if you have two internal SCSI controllers, the order of loading their drivers will change the device file assignment. sometimes, the existene of a USB disk-on-key in the system could change things - if the relevant USB driver, for some reason, was loaded before the driver for the SCSI disks. 2. devices in Linux go offline too easily - it's a major headache in SAN environments that support multi-pathing (i.e. where failure to send I/O operations has no reason to put a path as being offline). i would suggest that you look in your system logs - you should have long error messages before the device was put offline. basically, if a SCSI request timed out, the Linux kernel employs some recovery operatoins that include device reset, target reset and bus reset. if they all fail - the kernel marks the device as offline, and this is not always recoverable without a reboot (you can, in some distributions and kernel versions, mark the device as 'running' again - but then it might still get 'blocked'). if you can tell us a little more about the machine's confiugration - we may be able to tell you more about problem #1. regarding problem #2 - look in the logs, and see what you get. you'll need to translate the SCSI error codes into meaningfull things - look in /usr/include/scsi/scsi.h for the different flags that together comprise the SCSI error you see in the logs. --guy Noam Rathaus wrote: Hi, Hrm, before I go and start my service agreement that usually results in a eyebrow raising on THIS IS LINUX!
