 AIX boxes function on network, but exceedingly slow uploads I have a few AIX boxes (not installed from scratch, but 5.1) on two local subnets. FTPing files from a windows box: TO the AIX box goes 80KB/sec FROM the AIX box goes 5-6 MB/sec Although I'd like faster on a 100mbit network, I'd settle for fixing the "TO the AIX box" part. Any idea what is wrong? I've checked netstat -v, and there are no collisions/errors. I've checked the ethernet card configurations, and they all seem correct. Switching ethernet cards doesn't really help, either. Thanks in advance for advice, because I'm out of ideas. Michael Stumpf michaelstumpf @t yahoo d0t com      |

Better is to set static 100Mbit/Full_Duplex and do the same on switch port configuration. It should help. Note: it is not possible to change media_speed of being used network adapter although it is possible to change it on running system remotely executing following script/commands in the "at": /usr/sbin/ifconfig en1 down detach /usr/sbin/ifconfig et1 down detach /usr/sbin/chdev -l ent1 -a media_speed=100_Full_Duplex /usr/sbin/chdev -l en1 -a state=up /usr/sbin/mkdev -l inet0 Another soultion is to make change in database only then after reboot media_speed will be set as required regards, marek. |
