similar to: TCP MSS clampage

Hello, I have an interesting question. I can''t find a solution anywhere to this problem. I have an adsl connection which is able to send a full data packet in about 150ms. I want to cut this time down to decrease latency while serving files, so I thought I''d try and reduce the packet size for the offending upload streams (my webserver). The trick is that I also want all other

Clients: Some sites just show the top area not the full page. Some sites cant be reached at all. I think it 90% may be the MTU/MSS problem.

Hi,Andy Thank your very much! For the MLPPP LFI,I found that in Cisco configuration,it use "ppp multilink;ppp multilink fragmentation;ppp multilink fragment-delay 20;ppp multilink interleave " command to enable MLPPP LFI.So I think just realizing the same function on my linux router would be fine.But I got no idea how to do this on linux.So is there anything with iproute2?Would you

Hi I have a (bizarre) problem with ssh, which someone has suggested may be down to the MSS value being too high. I know that within Shorewall I can clamp the MSS value to the MTU-40 value, but is there a way I can set MSS to a discreet value? I just want to (dis)prove the MSS theory at the moment (I know it isn''t a real fix). Thanks, Keith

I have an internet router powered by gentoo+shorewall2.0.7+adsl(pppoe) but my clients(and gateway) cant access some websites----these sites must be okay,other sites are okay. The I believe it is caused by MTU or MSS, but I have no idea yet. Btw, the unaccessable sites are dynamic, it says: today I cant access www.oracle.com nextday I redail--to get another ip,I can access www.oracle.com. Help!

Hi all, I am trying to install the PPPoe server rp-pppoe-3.8 from Roaring penguin on centos PC (Centos 4.3, Kernel release 2.6.9-34.EL) but not able to start it.

I have a requirement which I guess it is not too unusually, however I haven''t quite figured out how to do it and couldn''t find any examples which handle that. I have made myself a Linux-based bridge, eth0 bridged with eth1 to form br0. In this bridge, I run ''tc'' script to handle QoS. So far nothing unusual. However, what''s different is that this

Hello all, I am trying to make a little bit more complex QoS/Shapping form and I need to shape a PPPoE conection that I serve to my clients. So this is the scope: client connects using pppoe so it gets an IP address (from pppoe pool) and open an interface into my linux box interface for this client is ppp0 client has got an ip 1.1.1.2/32 and it is poiting to pppoe-server 1.1.1.1 So,

hi all. i am currently now serving PPPoE in my area. i had a script generated from tcng that worked perfectly before i started serving PPPoE. the issue is not in the script it self BUT in that "tc" code is not shaping on the ethernet anymore BUT INSTEAD on the pppX devices. I tested it and talking jargon, what should i do? The issue is that for each PPPoE login, PPPoE-server
