Hi folks, I have the following in my firewall (condensed version) [CentOS 4.2: 2.6.9-11.EL.i686 kernel]: INPUT: --state ESTABLISHED,RELATED -j ACCEPT -p tcp -j REJECT --reject-with tcp-reset -j REJECT OUTPUT: ACCEPT The connection is over a wireless link so packets _do_ get dropped even though throughput is around 100-400 kB/s (depending on atmospheric conditions, etc.) Now I've noticed

I was comparing some traces from SCP and SFTP when transferring the same file 200MB file between the same host pairs. Even when I put SFTP in batch mode I noticed that I saw 403208 bytes from the receiver in comparison to 3368 bytes with SCP. I've attached the relevant output from tcptrace below (the b->a column is the return side of the trace). Mostly I'm just curious as to what

A few days ago I wrote complaining that my new, cheap Compaq Presario (sr5010nx) could not create and maintain a dsl connection using Centos5. I was puzzled that that Ubuntu - with pppoeconf - would work just fine but Centos5 could not be configured. (cento4 -also) Eventually I googled and found a bug report for the r8169 Gigabit ethernet driver. Conclusion - there is a patch in new kernels

Hi all, I have this Fedora 7 system with 3 ethernet cards, eth0 servicing the local network, eth1 connected to ISP1 and eth2 connected to ISP2.

I have managed to use the connection to ISP1 for all internet connection, but failed to use ISP2 at all!

Hello, how it''s possible to download something from ftp servers without site-to-site transfer enabled? If the data transfer connection will be routed through another outgoing interface than the command connection the server denies the connection. Are there any solutions for instance with ip_conntrack_ftp module or similar? -- Markus Schulz

Hello, I would like to know if it is possible to have multiple ADSL connections going into a box running shorewall be pooled into one connection. IE: shorewall is a gateway/firewall for a server and have the server obtain double the speed to the net by "splicing" both ADSL connections into one. Regards, Justin Lorne Kaufman
