similar to: XP client missing ACK when manipulating directory

Hi. Is it possible to disable the TCP Delayed Ack? I would need to do some TCP performance test and it could be very useful to be able to control this kernel parameter. Thanks. Antonio

Guys I''m a bit rusty and in a hurry, can anyone share with me how to prioritze TCP/ACK packets on an outgoing interface... I need these acknowledgements to get through on a congested DSL link...

Uploading a >32MB file from a recent curl to tftpd fails because when the block number rolls back to 0, tftpd transmits the option ack again, instead of transmitting an acknowledgment for the block received. You don't see this problem when using the bundled tftp client because it doesn't set any of the options when uploading a file. Attached is a patch that fixes this, tested against

I just tried, on a whim, to use an OpenSSH client vs SSH 1.2.26 client, and I can connect with it... Something drastic change between pre23 and pre24? Then again, I can't get pre23 to work anymore either, after further investigation :( OpenSSH clients connect no problem, just not the old SSH 1.2.26 clients ... Marc G.

Hi Marc, I am seeing this exact same problem on OpenSSH-2.5.1p1 compiled on a PowerPC. The same code compiled for an x86 machine works fine. Your messages on the list didn't seem to indicate any resolution to this problem. Have you figured out how to make it work? checksum: 2d2711e2 stored checksum: 2d2711e2 checksum: 72f2b13c stored checksum: e230f836 Disconnecting: Corrupted check bytes

This time the problem is that the ssh server only sets TCP_NODELAY for interactive (tty) sessions or if X11 forwarding is enabled. Neither of which are true for the use of the sftp subsystem. This hurts upload performance for sftp/sshfs. I'm not sure why this hasn't cropped up earlier. Were there any TCP_NODELAY related changes in the sshd code recently? Is there a reason not to

Hi guys, My asterisk didn't send ACK for 200 ok message just for one specific extension. The ATA used by this extension is used by other extensions, with same firmware version. Looking in wireshark, I saw that ATA sent 200ok and asterisk didn't confirm it with ACK. The ATA did this during 20s, after this, asterisk hangup the call. This issue happen only one asterisk start a call.

I am trying to debug a SIP issue, between an Asterisk 1.2.32 system that is behind a network device to which I don't have ready access, which is performing NAT with possibly some kind of SIP ALG, and an Asterisk 11 system on a public IP. My question is very specific, and I don't need right now to discuss the ins and outs of the above setup. What I am seeing is that when I have set up a
