[opensuse-security] Proplem with scp under SuSE10.1
Hello, i have a poblem with the command scp, to copy large files to another host. After a few Bytes I got the message on the receiver: 'Disconnecting: Corrupted MAC on input' and on the sender 'received disconnect from xxx.xxx.xxx.xxx: 2: Corrupted MAC on input'. The receiver host is a SuSE 10.2 and the sender host is a SuSE 10.1, both host with all updates. When I search in the net I found the problem in context with the kernel and the nic's. Sender nic: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express Receiver nic: Broadcom Corporation NetXtreme BCM5714 Gigabit Ethernet (rev a3) Has anyone an idea to solve the problem?

I fail to see what your problem has to do with "security". You will probably get more responses on the standard list. However... We were doing experiments in routing with two suse 10.2 machines interconnected directly with gigabits cards, acting as routers for three other PCs. These two, lets say A and B, did not see each other correctly. A could ping B, but B could not ping A. Looking with wireshark, I saw that B was sending ARP requests on the interface to determine the MAC address of it's partner and getting no response. We switched to another card, and it worked. We removed the original card (brand new gigabit, I think from Realtek), cleaned the contacts with a rubber eraser, reseated, and it worked fine. Go figure. The point why I mention this is because the card failed to get a MAC address from the other side. I think it was some kind of hardware failure. - -- Cheers, Carlos E.

Hi Klaus, maybe the receiver's NIC firmware is out of date? We have some servers in use which have NICs installed that were known to be shipped with need of a firmware uodate. Every then and now such a NIC would 'forget' it's mac on reboot.

We had setup an accounting tool for student housing with switch level security (locked when switched nic). On broadcom and nforce boards mentioned nics we had a lot of broblems because we had to unlock this security features for their nic on switch level. If you want GBit lan please inform yourself which nic is the best solution for it and which one works good with your distribution of choice! If you think it's to expensive have a look at the online trading or second hand maybe there you find somewhat cheaper. There is another thing to mention: Some mainboards forget their ethernet adress if you do a firmwareupdate and afterwards forget to setup default values (this isn't documented or very hidden on some webpages). If you don't do so you have to send back this board or buy a different nic! Regards Philippe - -- Diese Nachricht ist digital signiert und enthält weder Siegel noch Unterschrift!

I don't think that the firmware is the problem. I have had the problem with one servers that run under SuSE 10.0 and on another that run under debian. I dont really solve the problem but I change the receiver thar runs no under SuSE 10.0. The problems started after the last kernel update in June before this all works fine since 1 year. I think it is a problem with openssh and the kernel. Have anyone the same problem? Klaus
