It was my problem. My network interface was in 100Mbps half-duplex instead of 100Mbps full-duplex (the switch was in 100 full).
I was using DHCP to configure the interface and for some reason it came up as half (even though a 4.3-BETA box elsewhere around here comes up in full-duplex). It seems that Cisco equipment doesn't autonegotiate well as we have seen this problem on other UNIX systems (HP-UX in particular) so we try to tie everything down these days. I have now tied down the interface at my end with this in /etc/rc.conf: ifconfig_xl0="inet 10.1.2.3 netmask 0xffffff00 media 100baseTX mediaopt full-duplex" I no longer have problems with NIS client performance. i.e. when doing my huge FTP tests I can open xterms and they now start immediately. Sorry for the false alarm. P.S. I would still like to try using DHCP but *NOT* autonegotiating. Is this possible ? Should the below work ? ifconfig_xl0="DHCP media 100baseTX mediaopt full-duplex" --- Excerpt of my complaint earlier re: NIS client caching issues --- I can see this poor performance in just trying to start an xterm under network load and can create 24 -> 32 second delays with a test as follows: % cd /usr/ports/distfiles/xc % ftp nis-server (my home there is local to that box) ftp> prompt ftp> mput *.tgz Just after pressing enter on the above line, start two xterms. Now thats quite a bit of data even when myself and the server are on 100Mbit/s full-duplex switched ethernet links. -rw-r----- 1 user group 237098 Oct 3 17:55 X336contrib.tgz -rw-r----- 1 user group 17388037 Oct 3 17:55 X336src-1.tgz -rw-r----- 1 user group 14834083 Oct 3 17:55 X336src-2.tgz -rw-r----- 1 user group 21994230 Oct 3 17:55 X401src-1.tgz -rw-r----- 1 user group 18971060 Oct 3 17:55 X401src-2.tgz -rw-r----- 1 user group 23880758 Oct 3 17:56 X402src-1.tgz -rw-r----- 1 user group 18918369 Oct 3 17:56 X402src-2.tgz -rw-r----- 1 user group 24990773 Oct 3 17:56 X410src-1.tgz -rw-r----- 1 user group 22496001 Oct 3 17:56 X410src-2.tgz The transfers go well with the larger files achieving between 5.14 and 7.78 MB/s however the xterms dont appear until after the whole FTP mput is finished. i.e. the timing was: T+0 I press enter on the "mput *.tgz" FTP command T+3s I launch xterm 1 from another xterm T+5s I launch xterm 2 from another xterm T+25s FTP mput completes T+27s xterm 1 appears on my display T+37s xterm 2 appears on my display Now xterm 1 has the message "yp_first: clnt_call: RPC: Timed out" as its first line and xterm 2 has two of these messages. So I'd like to do a little bit of investigation and was wonderring if other people have some insight as to where to look. This is not a short term problem and has been present across many months of -CURRENT (last build 19th September 2001 and typically built monthly) ever since I became a NIS client about 18 to 24 months ago. Further info: The nis-server runs HP-UX 10.20. The network is expensive Cisco switched ethernet with everything tied down to 100 MBit full-duplex at all ends except my FreeBSD box which is autonegotiating its "3Com 3c905B-TX Fast Etherlink XL" card simply because I have the line ifconfig_xl0="DHCP" in my /etc/rc.conf and I dont know how to set media options with ifconfig when DHCPing (anyone ??). -- Matthew Thyer Phone: +61 8 8259 7249 Science Corporate Information Systems Fax: +61 8 8259 5537 Defence Science and Technology Organisation, Edinburgh PO Box 1500 EDINBURGH South Australia 5111 IMPORTANT: This email remains the property of the Australian Defence Organisation and is subject to the jurisdiction of section 70 of the CRIMES ACT 1914.
