Hi - I have 3 RH 6.2 servers networked in the following manner: +-- eth0 -- [file server] ------- eth1 --> LAN | -- ppp0 -- [firewall] -- eth0 --< | +--- eth0 -- [internet server] -- eth1 --> LAN I have file server mounting the firewall and internet server via NFS, and use the file server to perform nightly backups to DAT. I'm seeing some strange network slowness which is affecting connections to the firewall from the other servers. When copying a file from the file server to the firewall over NFS I only get a throughput of about 5Kb / Sec (if I'm lucky) over a 10BaseT connection. I just tried to do a test copying a file from the firewall to a server using scp but received an error: Received disconnect: Command terminated on signal 11. I tested scp between the other servers and it works fine... there's no such problems between the file server and the internet server, but both have problems communicating with the firewall - so I'm pretty sure it's the firewall at fault... Following are some stats for the firewall machine... I was hoping that someone may be able to point me in the direction of a process to troubleshoot this situation and work out what's going on. Note that this slowness does not only affect NFS - although we don't really notice it since the most of the traffic this machine sees is ipchains firewall / masqueraded traffic over a 56K link. #top 9:44am up 20 days, 35 min, 3 users, load average: 0.04, 0.04, 0.01 60 processes: 59 sleeping, 1 running, 0 zombie, 0 stopped CPU states: 2.1% user, 2.2% system, 0.0% nice, 95.6% idle Mem: 38700K av, 27176K used, 11524K free, 12520K shrd, 8016K buff Swap: 66488K av, 3780K used, 62708K free 7012K cached #ifconfig eth0 Link encap:Ethernet HWaddr 00:E0:29:16:64:B5 inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.xxx Mask:255.255.255.240 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3341455 errors:0 dropped:0 overruns:0 frame:31246 TX packets:4390377 errors:2 dropped:0 overruns:0 carrier:2 collisions:486 txqueuelen:100 Interrupt:5 Base address:0x290 Memory:c8000-ca000 #cat /proc/interrupts CPU0 0: 173020008 XT-PIC timer 1: 17 XT-PIC keyboard 2: 0 XT-PIC cascade 4: 104457121 XT-PIC serial 5: 7690294 XT-PIC SMC EtherEZ 8: 1 XT-PIC rtc 13: 1 XT-PIC fpu 14: 18218332 XT-PIC ide0 NMI: 0 -- Telezygology Manager, Technical Systems Ph (+61 2) 992 992 88 Fx (+61 2) 992 991 88 _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
