what is the limit on the arp cache entires ?! Does someone have very big LANs with linux-routers ? How big ? (i mean flat L2 network, not segmented) I want to know how much can my net can scale ? thanx _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I have been trying to figure out why my domU NIC becomes unreachable (could not even ping) at various times. (Normally when the server was trying to update clamav from the various busy mirrors at 4am). There also seemed to be some latency when connecting which I chalked up to it being a virtual machine. When I checked my logs, I found thousands of : Nov 17 04:07:52 nomad kernel: Neighbour

Hopefully this is an easy question.... I''m using a leaf router (bearing) running shorewall. Three interfaces net, loc, and dmz. Only one computer in the dmz and its being proxy arp''d. External and internal (net and loc) can reach the dmz but the dmz cannot reach the isp''s gateway and beyond, but can reach a system adjacent to the firewall.

I want only to ignore the arp request for alias ip ,at the same time I don't want disable the arp function of the interface ? How do ? thanks! --------------------------------- DO YOU YAHOO!?

Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

Hello, I''m following this HOWTO http://linux-ip.net/html/adv-multi-internet.html to route outgoing SSH from a secondary ISP. I can see using tcpdump,jnettop,iftop that when one of the computers located in my internal network is trying to SSH to a box online using SSH, packets are routed via the secondary internet ethernet card. However, packets don''t seem to know how to get back.

Hello, I'am trying to efi-netboot a HP ProLiant DL120 Gen9[1], that has multiple NICs, one embedded 2-port and an extra 4-port, so I got to the HP/EFI/multinic problem. I read through the multinic mailthreads and using current master[2], it booted successfully to syslinux but then another problem manifested: Syslinux for some reason asks the gateway and not next-server about ldlinux.e64 (I

Hi! Me and two friends are trying to get a VPN working, but we cant get routing between two tunnels. This is how it looks, all servers (192.168.*.1) are running IP Masquerade to enable the other computers behind them to access the internet. Both elayne and glenn are connecting to melc, and the tunnel between melc and glenn are running TCPOnly because that glenn doesnt have a public IP (it's

Hello all. I know this does not directly relay to Ethernet bridging but I need some advise... anyone want to give me some info/help on the subject. In the interest of multipath routing I need to know if it is possible to do a one-way arp spoof. Lets start with the machines layout... br1------ADSL br2------cisco router-----serial line. br0-----Internal network. I already have

Hello alltogether, I''m new to the list, so please excuse any violations of listiquette...
