Hi list, I install dahdi-linux successfully with the module of oslec for the echo, but when I specify it in the system.conf the echo canceller oslec it shows me errors: DAHDI_ATTACH_ECHOCAN failed on channel 4: Invalid argument (22) I see that the echo cancellers is supported: mg2, kb1, sec2, and sec because oslec is not supported?, but he has support to compile it with dahdi_linux! best

...1) I'm getting incredibly slow file copy performance. Using smbclient on a linux machine on one size of the WAN, As you can imagine, this makes all of our file shares unusable over the WAN. It's not an issue with WAN performance, because using scp to transfer the same file, I get speeds of ~145k/s. A tcpdump of the file copy of ~2MB file that actually times out with the following error is up at: http://emagiccards.com/james/copyfileusingsmbclient.tar.bz2 -- Timeout Error -- Short read when getting file \Finance\monthly_reports\Aug07.xls.
