Tonight I discovered that I am unable to access my 3Com SuperStack 3300 switch from either of my Linux hosts. Note that I can use the switch, I just cannot manage the switch with either Telnet or http. However, my Windows based hosts have no problem accessing the switch (via telnet or http). After a bit of research, I've found a problem with the arp entry for the switch on both Linux hosts. The actual mac address reported on the switch is 00:90:04:b8:b7:d8. My Linux hosts report: # arp -an (host 1) ? (192.168.2.254) at 00:01:03:7B:DD:72 [ether] on eth0 # arp -an (host 2) ? (192.168.2.254) at 00:01:03:7B:DD:72 [ether] on eth0 However, my Windows hosts report the correct mac address in their arp tables. I couldn't find this documented anywhere, so I thought I would go to the source. The Linux hosts are both running 2.2.17-21mdk (Mandrake 7.2) and both machines are using the stock eepro100 driver that shipped with 'Drake 7.2. Also, arp -d 192.168.2.254 doesn't seem to kill the entry. Any ideas? Thanks! John LeMay Jr. Senior Enterprise Consultant NJMC, LLC. [tag] It is pitch black.
