I *think* we are finally making some progress in tracking our elusive performance problems. After employing a second 10Mb link from our ISP, along with another firewall box and proxy, we were able to determine the problem *is* our firewall. We don''t know exactly why yet, but our sporadic slow web access seems to have gone away since swapping a new firewall in this morning. The

Hi All, For my issue, first thanks to ALL, I have some idea of it. Also Thank Peter for his kind remind, I would become one good guy in this list. Most mentioned MTU, but how I assure that the problem is just MTU, how I debug it? Here is my bridge configuration: Internet | | Gateway | | eth0 Ethernet Bridge | eth1 | H u b ( one normal hub

Could the problem be that the e100 can do IP receive checksumming on the board, but the eepro driver doesn't enable it. When the board is doing checksum offload, then the csum field isn't set. Please try disabling receive checksumming on the e100 driver modprobe e100 XsumRX=0 If this is the problem, it exists both 2.4 and 2.6. On Wed, 27 Aug 2003 18:24:57 +0200 Hannes Schulz

I have tried unsuccessfully to run both Shorewall 1.2.x, 1.3.x with Proxy ARP on a Red Hat 7.2 machine. The machine was configured as the external firewall as per the ''belt and suspenders'' layout given at http://www.skippy.net/linux/firewall/ The firewall appeared to function correctly in all functions except proxy ARP, however I must say I did not test exhaustively. After

Ok, I''ve flogged this issue probably longer than some of you can stand by now. (remember, I''m the nut trying to use a PPro200 to support ~500 users on a 10Mb internet link :o) To appease those who think I''m nuts, I am ordering a new firewall shortly to allow for future growth. (probably a Dell PE750 with P4/2.8 and dual GE nics.) However, since I have yet to prove

I figured I should post this because before I went to do it I searched the web for caveats etc and didn''t really find much. So anyway, I set up bonding + vlan for a project. Computer is dell powerdge 350 with 2 intel 82559 10/100 nic running stock 2.4.20. I tried both the eepro100 and the e100 drivers for the nics, both work 802.1q and bonding are modules. Switch is cisco 2924xl-en

Just purchased a couple of T100 and E100 cards in order to interface from our company's proprietary system through a linux gateway. I am new to Asterisk and Digium. After installing the T100 card, I went looking for drivers for this card. Are the drivers built into the Asterisk application? If so, how do I enable the card through Asterisk? Are there any good getting started documents for a

I four nodes setup to do active-backup bonding and the drivers loaded for the bonded network interfaces vary between tg3 and e100. All interfaces with the e100 driver loaded report errors much like what you see here: bonding: bond0: link status definitely down for interface eth2, disabling it e100: eth2: e100_watchdog: link up, 100Mbps, full-duplex bonding: bond0: link status definitely up for

Hi all! I want to assign a physical network card (e100) to a domU: I think Dom0 is ok but domU does not recognize the pci nic. into DomU I don''t know wath should I see: I have nothing in dmesg nor in messages... Into Dom0 I have this modules.conf: options pciback hide=(0000:03: 08.0) install e100 /sbin/modprobe pciback; /sbin/modprobe --ignore-install e100 This is dmesg: pciback

2.0.6pre3 compiles and installs under FreeBSD 3.2-RELEASE; however, throughput from an NT 4 SP6 workstation with domain security and only TCP_NODELAY as a socket option is clocking around 200K/sec for large files (65MB). Hardware is PPro200, single CPU kernel (never have gotten 2.0.5 or later to work SMP), Adaptec 2944UW/3 Quantum 9GB Atlas II wide diff drives (clock 9MB/sec using bonnie), Intel

With today''s build, my domain 0 crashes during boot when it tries to bring eth0 up (it''s an E100). cb->prev (eax) is NULL in e100_exec_cb() (e100.c:827). Just from code inspection, I don''t see how this can be. e100_alloc_cbs() was just called, which looks like it should have correctly linked up all the cb->prev/cb->next pointers. It happens regardless of

Hello list, I'm trying to reuse a fairly old PC based embedded system. It has no video output at all, no VGA, nothing older, and no keyboard / mouse connectors. The console is on a standard RS232 interface, including BIOS output and the minimal BIOS loader. The BIOS emulates / redirects text output to and keyboard input from the console RS232 interface, but unfortunately, this emulation

Hello, I manage a number of servers all running 2.4 (same problem exists with 2.6). My problem is that since a few bridge versions ago, I've had to modify net/bridge/br_fdb.c in the br_fdb_insert() function -- to get rid of the checks that produce this error: Jan 16 10:35:31 host15 kernel: tap_0: received packet with own address as source address Jan 16 10:35:33 host15 kernel: tap_0:

So I just finished doing a fresh install of CentOS 6.3. The machine has three ethernet ports in it: one on the motherboard (VIA Rhine), and two add-on cards, an Intel Pro100 and an old SMC1255TX. When CentOS comes up, this is what I see in the dmesg output: # dmesg | grep eth e100 0000:00:08.0: eth0: addr 0xf6043000, irq 16, MAC addr 00:02:b3:be:02:87 eth1: ADMtek Comet rev 17

Hi! I have some problems with an bridge between wlan0 and eth0 device... It works and I can from both sides ping the router with the bridge device but I cant ping the devices from other net so I cant ping wlan devs from eth net and other way around the wlan card is an atmel usbw11 from linksys and eth is a intel e100 10/100mbit nic I have configured the bridge according to the how to and

Hi, Hopefully this won''t be too off-topic (I''ve seen both bonding & vlan mentioned on the list, but not really together). I''ve tried to get bonding (2 x 100Mb EEPro, but will want to try on 1000BaseT) and vlans to work together, but without luck. I can get them working fine (seemingly at least - I didn''t tried bursting on the bonded port) individually.

Greetings, We have purchased an IBM BladeCenter and I am in the process of testing Linux installation on these things (boot off SAN i.e. qla2300 driver, not using internal drives). My distro of choice is Debian, however, since I'm really not interested in trying to hand compile all the drivers, I decided to try CentOS (which I'm so far very impressed with). On boot, as with the

I used to be able to modify my modules.conf file so that certain NIC cards would load specific drivers. Has this changed in kernel 2.6 i.e. <snip /etc/modules.conf> alias eth0 e100 alias eth1 e1000 </snip> It used to be that I could reverse this order and eth0 would be the GigE card.
