Fwd: Different behavior of net.ipv4.ip_local_port_range between RHEL-5 and RHEL-6
Forwarding just in case anyone is familiar with this on CentOS, thanks! -- Hello, Just found that net.ipv4.ip_local_port_range has different behavior between RHEL releases: until v6 although you have multiple source IPs you can only use a fixed number of local ports, seems that "ip_local_port_range" is a global configuration or limitation. On RHEL-6 kernel (testing with 2.6.32-279) you can bind() to N local port...

gluster peer probe failing
Thanks, but my current settings are: net.ipv4.ip_local_reserved_ports = 30000-32767 net.ipv4.ip_local_port_range = 32768 60999 meaning the reserved ports are already in the short int range, so maybe I misunderstood something? or is it a different issue?

NFS config problem
Hello, First let me say how much I appreciate Shorewall. I just downloaded shorewall-1.3.14.tgz, built and installed it without error, and had it working with only minimal fiddling with the config files. I''m having trouble getting NFS to work with Shorewall. I followed the info on the "Ports required for Various Services/ Applications" page but I couldn''t get it to

https://review.gluster.org/#/c/17494/ will it and the next update of 3.10 should have this fix. If sysctl net.ipv4.ip_local_reserved_ports has any value > short int range then this would be a problem with the current version. Would you be able to reset the reserved ports temporarily to get this going? On Wed, Jun 14, 2017 at 8:32 PM, Guy Cukierman <guyc at elminda.com> wrote: >

local ephemeral ports usage and distribution / inet_csk_get_port()
...client to connect to an iperf server (running either CentOS or Debian) requesting N parallel TCP connections. I notice that the local ephemeral ports used are not consecutive and are always even ports numbers. This can change to "only odd ports numbers" depending on the setting net.ipv4.ip_local_port_range, but basically, the idea is the Centos kernel does "+2" when finding a local port for socket, not doing +1. Doing a netstat, generally speaking, only even (or odd) local ports are used so this does not seem application dependent. It's possible, however, to request both odd and even...

Sometimes it will resolve itself after a few minutes and sometimes it needs to be restarted (it may fix itself, I usually get a phone call if it goes

hpa-tftp source port selection
Good day, I'd just like a bit of information about the source ports that hpa-tftp uses for its TFTP file transfers. We're using it to transfer files across a network that we have heavily firewalled. So, we'd like to know which ports the TFTP server might use as the source port for its data transfers and/or any ways to configure a range that it can use. I dug through the man page,

udp question
i all I use linux as GiGE router and have 6 NIC on it Those days the NIC interrupt takes around 100% CPU but the system is 4G memroy and 8 CPU. I can't see any error packet in this NIC interface too After I block the udp, the %CPU drops. but the UDP only takes around 8M in general We use UDP traffic for voice. Do you have any suggestion ? increase the kernel parameter? Thank you so much
