vsftpd resource hogging on 4.2
by Chris Mauritz 07 Nov '05

07 Nov '05

I've just noticed an odd bit of behaviour with 4.2. I'm using FTP to send a number of large binary files from a windows 2000 machine to a CentOS 4.2 system. Both systems are similarly configured (Athlon64 3200+, 1gig RAM, 80gig system disk, 1.2TB scratch RAID 0 array, gigabit ether to a dumb switch on which they are the only hosts). On the very first file, about 17.5gigs, I got about 30MB/sec. Not spectacular, but reasonably fast. On subsequent files, I only get about 25% of that throughput and vsftpd on the CentOS machine is eating 99.9% of the cpu, which is probably what is killing performance. Both machines are reading or writing to a RAID 0 array of 4 reasonably fast drives so I'm assuming that's not the bottleneck. I've also disabled SElinux and iptables on the Linux machine since the machines are in a non-internet sandbox. Any suggestions would be greatly appreciated. Cheers,

Legato Networker packs a sad (it handles sparse files, but it takes a *very* long time to do so). ;-) C ======================================================================= Attention: The information contained in this message and/or attachments from AgResearch Limited is intended only for the persons or entities to which it is addressed and may contain confidential and/or privileged material.

I resolved the problem with the PuTTY in XP. but what you mean running/accessible via firewall and system-config-securitylevel? in XP or CentOS? and what is this? can i use samba in centos? and how connect from XP? ----- Original Message ----- From: George Ginis To: ivazquez(a)ivazquez.net Cc: centos(a)centos.org Sent: Sunday, November 06, 2005 11:24 AM Subject: Hi Ignacio Hi Ignacio, apology for my English... my name is George Ginis... what you mean running/accessible via firewall and system-config-securitylevel? in XP or CentOS? and what is this? the PuTTY I have in XP or in CentOS? thank for your answer... By default CentOS doesn't have ftp, telnet, nor rlogin services running/accessible via firewall. Use an ssh client such as PuTTY. And don't forget to use system-config-securitylevel to open the ssh port.

auto hide gnome desktop TOP panel - solved
by Jerry Geis 06 Nov '05

06 Nov '05

I turned on the auto hide of the TOP panel on gnome desktop. I does hide but I still see like 2 or 3 pixel lines of the panel??? How can I completely hide the top panel? I tried change the number of pixels in the panel it always still shows a couple pixel lines. I have a dell inspiron 8200 laptop. THanks, for any suggestions. Jerry -------------- Using gconf-editor path /apps/panel/toplevels/top_panel I found auto_hide_size=6 and change to 0 That seems to have taken care of it. Jerry

Sendmail
by Sam Drinkard 05 Nov '05

05 Nov '05

I am apparently doing something wrong somewhere, as I cannot get sendmail to listen on port 25. I've edited the sendmail.mc, commenting out the daemon process on port 127, rerun the m4 macro, rebuilt per documentation on sendmail, yet I still get a refusal on connection when trying to telnet to port 25. Is there something else I'm overlooking causing sendmail to not listen on port 25? Getting desperate now! Sam -- Snowman
