Re: [CentOS] Performance of CentOS as a NAT gateway
LAN-to-gateway traffic (e.g., a test FTP of a large file from the gateway to a machine on one of the LANs) begins to degrade as the LAN-to-internet traffic increases. That's not surprising, but it degrades disproportionately, i.e. when the FTP begins to show intermittent stalls, the total traffic visible at the router on the internet side of the gateway is only in the just-over-10Mb/s range. Once we get to this point, no matter how many more LAN-to-internet connections become active, the router on the internet side never sees much over 10Mb/s of traffic. We're not losing data or having an unusual number of connection timeouts; each connection just slows down. We figured on some slowdown for NAT, but not 80%+. LAN-to-LAN traffic that doesn't involve the gateway behaves more like we'd expect, but I'm not sure that eliminates the switch as the culprit. Maybe it is time for some kernel networking tuning. This will definetly require more memory, but should speed things up. This is on a CentOS 4 machine .. I don't have a CentOS 3 machine to test on. Add the following lines to /etc/sysctl.conf net.core.rmem_default = 67108864 net.core.wmem_default = 67108864 net.core.rmem_max = 67108864 net.core.wmem_max = 67108864 net.ipv4.tcp_mem = 4096 67108864 67108864 net.ipv4.tcp_rmem = 4096 67108864 67108864 net.ipv4.tcp_wmem = 4096 67108864 67108864 net.ipv4.ip_local_port_range = 32768 65535 net.ipv4.tcp_max_syn_backlog = 8192 After adding these lines, run "sysctl -p" Hope this helps.

If you mean you mount the FS over /, you lose access to the real root when new apps start. A mount "hides" all items under the mounted upon directory. Existing apps may be able to access these hidden ones, I'm not sure, since they have open files in the underlying structures already. If you mean you are mounting on some directory in the root file system other than /, a very common scenario, there is no problem. As Scott said, FS info is unique to each partition and they are additive *except* as they "hide" everything contained within the directuroy upon which you mount the FS. You effectively lose access to the hidden stuff by *new* processes (unless they inherit open file descriptors for the hidden stuff I think). > > > > thanks for help > No. The inodes are part of the underlying partition, and it doesn't matter > how > many filesystems are nested or how deep. > If you have say a var partition under the root partition, and you use all the > inodes in the var partition, you can still add files to the rest of the root > partition. > -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I would then suggest getting a wireshark setup to monitor the traffic as it passes through the gateway. If the gateway host doesn't have a GUI then I suggest another host with 2 interfaces, one on each side of the NAT and compare the timestamps of traffic coming in from the Internet to the NAT, out of the NAT to the client, in to the NAT from the client and out of the NAT to the Internet.

[CentOS] Language interfaces and X.Org sessions per user
Q1: Is it possible different users to have different language interfaces (menus etc) on the same machine under X.Org (GNOME or KDE)? Q2: Is it possible to have more than one X.Org sessions running on the same machine, so as different users to log in at the same time, and switch between users X.Org sessions (one using GNOME, other using XFCE) by using the usual Ctrl-Alt-Fx keys? Thanks in advance. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Looks like a known bug and a newer version of kaffeine has corrected the problem. Deleting the offending file does not help because it is registered in the rpm database. Fedora Core 6 has kaffeine 0.8.4 which does not have this problem. The best method is to get the src file and rebuild from there. In this particular case, the Fedora binary seems to install as is (but still not recommended). Or send a request to dag and ask for a newer version of kaffeine.
