Hi,
I've a network problem on my Fedora Core 1.
on my switch the 100 led is ok.
But if I make an mii-tool command I've this result :
eth0: 10 Mbit, full duplex, link ok
And it's bad. Why the led on my switch ok in 100 Mbit but mii-tool see it with 10 Mbit ?
I've try this : mii-tool -v -A 100baseTx-FD
But no changes..
Thanks for help ;D

Are you certain that it is saying 100Mb? I have seen several switches that have a slightly different color for 10/100.

Did you try -F to force it?

Yes for sur ! My old Linux Mandrake server is ok at 100 mbits and led is ok too !

After this command :
mii-tool -v -F 100baseTx-FD
Result :
[root@bisol root]# mii-tool eth0: 10 Mbit, full duplex, link ok

Hmmm, had a poster with a similar problem last week. It seemed to come down to either a problems with mii-tool and ethtool or a problem with the mii interface in the NIC driver. I put my money on the driver as both mii-tool and ethtool work for myself and others.
However, I think this same advice should pertain to you both. Just because the software interface is returning incorrect information doesn't mean that the mii hardware isn't doing it's job. Link negotiation happens at the hardware level even without the presence of a driver. WOL cards maintain link even when the machines they are in are powered off. Software, if properly implemented, can allow you to query and sometimes even set mii parameters, but usually this is best left to the hardware.
Does your NIC have both link and speed leds? If so, what speed do they indicate? I would be willing to be they show 100Mbps. In this case, I would trust what the hardware is telling you and not what the software is telling you.
Mind you, I don't think it's good that mii-tool and ethtool are reporting faulty information, but I do think that if you dig deep enough, you're going to find that the problem is with the NIC and the available driver. You might check the manufacturers page to see if there are any known problems with linux in general and fedora in particular. While you're there, look into the manufacturers policy on linux support and also their usage of hardware tweaks. Not all OEM chipsets are created equal.
BTW, what NIC are you using?

2 led but my transfer rate is 5mo / sec. With my other Mandrake server I've (with same NIC) 11mo / sec ! Then it's all my problem !

What units are you using? Mo/sec is not one I'm familiar with. Also, what kind of transfers are you doing? You could be looking at an application issue rather than a driver/NIC issue.

Hmmm. 3Com with a cyclone chipset. Is it a new card? Hate to say it, but the 3Com name doesn't inspire the same warm-n-fuzzies it used to... At least we know the driver is sound. At this point I think it's time to ask if you have any other cards you could try?

Tinker with mii-tool. Specifically mii-too --advertise=media interface
media can be one of: 100baseT4, 100baseTx-FD,100baseTx-HD, 10baseT-FD, and 10baseT-HD.
What you should see is the link light go dark for a blink then a new physical layer connection is made. It could be that the negotiation is not good and kicking it again might link up .... I am finding that FD is hard for many inexpensive cards, switches and drivers.

I don't know about that. The problem is not that he can't get a link, he is and the connection is up at 100Mb/s, but mii-tool says it's only 10Mb/s.
As for full duplex having poor support on cheaper hardware, I can easily believe that. You don't really need (and can't really take advantage of) full duplex in anything but a server anyway. And it would have to be a busy one at that for you to really tell the difference.

Right... he is seeing a slow link that is also being reported as a slow link by mii-tool. This tells me that what the LEDs are stuck or something. Perhaps the link needs to be kicked into gear any gear to get hardware, LEDs and software all on the same page.
The LEDs "should" blink as the new rate is negotiated. This part could be important and give us hints about driver issues. Not all drivers support the layer that mii-tool uses. Perhaps some logic is stuck and...
It may be worth the effort to force it into slow 10baseT-HD one time them kick it up a notch....
Lastly do not ignore the posibility of a bad cable. Watchout for ports that have double plugs. A four port hub often has five connectors, one is cross wired so a null connection cable is not needed.
Snoop on the link for IP error symptoms even if the hardware is not reporting errors.
In general 'forcing' links presents problems because both ends need to play the same games or nothing works. Double check the other end too. Tidy up when done tinkering.

What if you get:
SIOCGMIIPHY on 'eth0' failed: Operation not supported no MII interfaces found
dmesg| grep eth0 gives:
eth0: registered as PCnet/PCI 79C970
It's an old box, does is not have support for MII?
ciao!

mii-tool does not valid correspond with the PHY on the NIC; mii-tool does not works with each card, especially old NICs.

Ah! I see said the blnd man...
So that means Sébastien was seeing 5 MegaBytes per second vs. 11 MegaBytes per second. By my math (and I'm only approximating link overhead) that's 50+ MegaBits per second vs. 110+ MegaBits per second. To me, that sounds like the difference between 100Mbps at half and full duplex respectfully.

If I understand it full duplex does not double the download speed. But rather upload can progress at the same time as download. This can be useful for a file-server where my reads do not conflict with your writes (on the network wire).
For download the ACK packets can flow without interrupting the up/download. Thus it can be possible to approach the theoretical bit rate in any one direction.
Am I confused?

That depends on flow control method.
With stop&wait flow control max throughput is always 50% of the max line bit rate, Full duplex helps very little on this. protocol like sftp are of this type.
Better flow control methods like sliding windows is very sensitive to the latency of ACK packets. typical efficency of s-window is ~60% on half dulplex and 80% on full duplex. 100% efficency is nvr achived with a single s-window connection though. http/ftp belong to this cat.

A few years ago when the 3C905 cards were the default card for our hardware we had alot of problems with the 3c905b variant. None of these cards would auto-negotiate properly to high speeds, all of them were replaced with 905c and the problem went away. This may be what you are encountering. Check your other server for the model of the card, it might be a newer one.

A distinct possibility. I also remember lots of framing errors coming off of 3C595s as well.
Of course I also remember a time (back in the thin-net days) when the 3C509b was the Cadalac, no that's wrong, they were more like the Rolls Royce of ethernet cards. We could get a good 30% more run length if we used only those cards. Just one from another vendor could take an entire segment down...
Now I see a 3Com card and cringe. Give me a Intel 10/100 any day.

Hi,
I'm having a problem with MySQL authentification with apache (for protected folders).
Now i'm using a thing like this :

AuthMySQLUser fdfdsfds AuthMySQLPassword fdsfdsfds AuthMySQLDB auth AuthMySQLUserTable users AuthMySQLNameField user_name AuthMySQLPasswordField user_passwd AuthMySQLGroupField user_group
require group fdsfds </Directory>
But i have 10 folders to make like this then i'm searching for a solution which is more simple... Have you ?
I have a second problem. For adding people in my auth database, i'm using PHPMyadmin and i make a SQL query but i need a more simple web interface to do this.. it exist or not ?
Thanks !
PS : Sorry for my BAD english but i'm french

If you need a specific web interface for only the purpose to fill the AUTH table for your Apache users, then simply write it your own using PHP. This can be done within a few minutes. Though I don't really understand what's simpler than using phpMyAdmin. You don't need to make SQL queries but could edit the table content like an Excel sheet. Or simply store SQL statement for reuse.

If you want to store the AUTH data in a MySQL database, then using mod_auth_mysql is the right way. But you should consider not to use .htaccess but to set the AUTH settings in the main httpd.conf or vhosts configuration. Please read
http://httpd.apache.org/docs-2.0/howto/htaccess.html#when
about pros and cons of using .htaccess.
