similar to: ping failure on dual-home using -I without default route

My Linux workstation (Mandrake 10.1 kernel 2.6.8.1) is dual-homed to two ADSL Internet providers. Card eth0 (192.168.9.250) is the default route and leads to an SMC router (192.168.9.254). Card eth1 (192.168.1.250) leads to a Linksys router (192.168.1.1). I''m not doing any NAT or PPPoE in the workstation - the SMC and Linksys handle it all. I know four commands that let you set an IP

Hi, There seems to be a problem with the timer resolution on x86_64. This is clear in ping results - I don't know if it's just a ping problem or if it manifests elsewhere as well. It does also affect mtr and traceroute times. I guess it's more a kernel issue than a CentOS problem, but is anyone else seeing the same? Ping results have a resolution of 10ms - so a ping <10ms

I need to install a web based cgi that provides an attractive interface for doing traceroutes, ping, and possibly mtr. I know it is not very difficult to write this but does anyone know of a good package that provides tools like this. The target audience is upper level management that have never seen a command line.

Keith, Thanks for the reply and the pointers. > Did you remember to activate kernel ip forwarding? > i.e. echo 1 > /proc/sys/net/ipv4/ip_forward ? I actually forgot to do this, but I have enabled it now in /etc/systctl.conf and can confirm now after a reboot that it's enabled. Unfortunately, still can't ping the node on the LAN. > and when I saw that I was about to cancel

What can I do to UNDERSTAND why, periodically, I can't reach www.centos.org (but everyone else can)? Every few months, http://www.centos.org just drops off for me and for me only. It's not the web site, because I can reach it via a proxy (e.g., TOR browser bundle) and other tests show it to be alive (e.g., http://www.downforeveryoneorjustme.com/centos.org or

Hi you all guys/girls from this list, I almost never use email lists, but this problem is driving me crazy. I use shorewall for a long time ( since version 1.2.x) but now I use it where I work, and here we now have 4 different ISP for redundance and because it''s cheaper then 1 ISP and a bigger link. 3 of 4 ISP I have no problems, but on the 4th ISP here goes my problem : I have a

I was wondering if anyone knows how accurate the values are when you do a "sip show peers" from the CLI. My configuration is: Asterisk box (192.168.1.102) -> gigabit switch <- PC running x-lite (192.168.1.100) the CLI reports 101 ms delay however, ping is showing <1ms delay Where is the extra 100ms coming from?

How do I allow traceroute to reach my server? Pings work fine but traceroute stops at the last hop before my server. If I shut off the firewall it reaches it fine.

I want to use --min-size to copy just large files (and their necessary parent directories), but everything I've tried copies *all* the source directories, and creates them empty on the destination even if they don't have any big files in them. I only want the minimal directory hierarchies that contain the big files. This doesn't work: $ rm -rf /tmp/foo $ rsync -ai --min-size

Hi all, I was trying to rebuild mtr (http://vault.centos.org/6.7/os/Source/SPackages/mtr-0.75-5.el6.src.rpm) and I keep getting: ==== Executing(%install): /bin/sh -e /var/tmp/rpm-tmp.gu9Ds0 + umask 022 + cd /root/rpmbuild/BUILD + '[' /root/rpmbuild/BUILDROOT/mtr-0.75-5.el6.x86_64 '!=' / ']' + rm -rf /root/rpmbuild/BUILDROOT/mtr-0.75-5.el6.x86_64 ++ dirname

I'm not surprised, given that it is in the repo. That's why I was asking if anyone tried building it themselves and, if so, did they have the same issue as I describe below? Alternatively, any tips/advice on solving my build issue would be helpful. digimer On 07/03/16 07:29 PM, Nux! wrote: > It built just fine in mock, results here > http://li.nux.ro/download/nux/tmp/mtr6/ >

I am having an extremely strange issue with a BL460c1 (G1) blade on a c7000 enclosure. I could not for the life of me get the machine to ping the gateway or any other blade on the same enclosure (yes, the subnet mask was correct & quadruple-checked); although pinging to the local IP works. I was almost convinced that it was a network or hardware issue; until I asked someone to try

Ah... I searched for half an hour for this function... you know, the help function in R could really be a lot better... But wait a minute... looking at this, it appears you have to pass in an expression. What if it is an unknown function, where you only have a handle to the function, but you cannot see it's implementation ? Will this work then ? -----Original Message----- From: Berton Gunter
