We have a NFS server which exports everyone's home directory, and I'm developing my Qualnet code on another machine (NFS client) under my home directory. However, when I make my code, linking takes extremely long time (it takes more than 5 minutes while on my laptop it only takes 15 seconds). I examed the /var/log/messages on the NFS server and it was like this: May 6 19:51:49 raptors kernel: TCP: [131.179.96.24]:985 to [131.179.96.25]:2049 tcpflags 0x10; syncache_expand: Segment failed SYNCOOKIE authentication, segment rejected (probably spoofed) The above message appears every time I make my code ( and only when I make my code). I turned on linux binary compatiblity on the NFS client because Qualnet needs to be run in that mode. Here are some more details: both the NFS server and client are amd64 machines. The server has 8 cpus and the client has 16 cpus. Any one can help me out? Thanks!!! Zhenkai For detail info for the NFS server is as following: kern.ostype: FreeBSD kern.osrelease: 7.3-PRERELEASE kern.osrevision: 199506 kern.version: FreeBSD 7.3-PRERELEASE #0: Tue Feb 9 12:59:50 PST 2010 root@raptors.cs.ucla.edu:/usr/obj/usr/src/sys/RAPTORS kern.maxvnodes: 100000 kern.maxproc: 6164 kern.maxfiles: 12328 kern.argmax: 262144 kern.securelevel: 2 kern.hostname: raptors.cs.ucla.edu kern.hostid: 2180312168 kern.clockrate: { hz = 1000, tick = 1000, profhz = 2000, stathz = 133 } kern.posix1version: 200112 kern.ngroups: 16 kern.job_control: 1 kern.saved_ids: 0 kern.boottime: { sec = 1267039765, usec = 441091 } Wed Feb 24 11:29:25 2010 kern.domainname: uclairlnew kern.osreldate: 702106 kern.bootfile: /boot/kernel/kernel kern.maxfilesperproc: 11095 "~/info" 2185L, 121063C kern.bootfile: /boot/kernel/kernel kern.maxfilesperproc: 11095 kern.maxprocperuid: 5547 kern.ipc.maxsockbuf: 262144 kern.ipc.sockbuf_waste_factor: 8 kern.ipc.somaxconn: 128 kern.ipc.max_linkhdr: 16 kern.ipc.max_protohdr: 60 kern.ipc.max_hdr: 76 kern.ipc.max_datalen: 100 kern.ipc.nmbjumbo16: 3200 kern.ipc.nmbjumbo9: 6400 kern.ipc.nmbjumbop: 12800 kern.ipc.nmbclusters: 25600 kern.ipc.piperesizeallowed: 1 kern.ipc.piperesizefail: 0 kern.ipc.pipeallocfail: 0 kern.ipc.pipefragretry: 0 kern.ipc.pipekva: 16384 kern.ipc.maxpipekva: 103321600 kern.ipc.msgseg: 2048 kern.ipc.msgssz: 8 kern.ipc.msgtql: 40 kern.ipc.msgssz: 8 kern.ipc.msgtql: 40 kern.ipc.msgmnb: 2048 kern.ipc.msgmni: 40 kern.ipc.msgmax: 16384 kern.ipc.semaem: 16384 kern.ipc.semvmx: 32767 kern.ipc.semusz: 152 kern.ipc.semume: 10 kern.ipc.semopm: 100 kern.ipc.semmsl: 60 kern.ipc.semmnu: 30 kern.ipc.semmns: 60 kern.ipc.semmni: 10 kern.ipc.semmap: 30 kern.ipc.shm_allow_removed: 0 kern.ipc.shm_use_phys: 0 kern.ipc.shmall: 8192 kern.ipc.shmseg: 128 kern.ipc.shmmni: 192 kern.ipc.shmmin: 1 kern.ipc.shmmax: 33554432 kern.ipc.maxsockets: 25600 kern.ipc.shmmax: 33554432 kern.ipc.maxsockets: 25600 kern.ipc.numopensockets: 74 kern.ipc.nsfbufsused: 0 kern.ipc.nsfbufspeak: 0 kern.ipc.nsfbufs: 0 kern.dummy: 0 kern.ps_strings: 140737488355296 kern.usrstack: 140737488355328 kern.logsigexit: 1 kern.iov_max: 1024 kern.hostuuid: 00020003-0004-0005-0006-000700080009 kern.cam.cam_srch_hi: 0 kern.cam.scsi_delay: 5000 kern.cam.cd.retry_count: 4 kern.cam.cd.changer.max_busy_seconds: 15 kern.cam.cd.changer.min_busy_seconds: 5 kern.cam.da.da_send_ordered: 1 kern.cam.da.default_timeout: 60 kern.cam.da.retry_count: 4 kern.cam.da.0.minimum_cmd_size: 6 kern.cam.da.1.minimum_cmd_size: 6 kern.cam.da.2.minimum_cmd_size: 6 kern.cam.da.1.minimum_cmd_size: 6 kern.cam.da.2.minimum_cmd_size: 6 kern.cam.da.3.minimum_cmd_size: 6 kern.cam.da.4.minimum_cmd_size: 6 kern.cam.da.5.minimum_cmd_size: 6 kern.cam.da.6.minimum_cmd_size: 6 kern.cam.da.7.minimum_cmd_size: 6 kern.cam.da.8.minimum_cmd_size: 6 kern.cam.da.9.minimum_cmd_size: 6 kern.cam.da.10.minimum_cmd_size: 6 kern.cam.da.11.minimum_cmd_size: 6 kern.dcons.poll_hz: 100 kern.disks: da11 da10 da9 da8 da7 da6 da5 da4 da3 da2 da1 da0 kern.geom.collectstats: 1 kern.geom.debugflags: 0 kern.geom.label.debug: 0 kern.elf64.fallback_brand: -1 kern.init_shutdown_timeout: 120 kern.init_path: /sbin/init:/sbin/oinit:/sbin/init.bak:/rescue/init:/stand/sysinstall kern.acct_suspended: 0 kern.acct_configured: 0 kern.acct_chkfreq: 15 kern.acct_configured: 0 kern.acct_chkfreq: 15 kern.acct_resume: 4 kern.acct_suspend: 2
