scp vs scpexe
I have a bit of a problem understanding why these 2 (scp and scpexe) behave so differently. I know the scpexe actually calls the command while the other runs from java, but with my setup (Fedora Core 3, jdk 1.5, maven 1.0.2), the scpexe takes a very long time to complete, but works every single time. While the scp executes much faster but gives me sporadic SSH_MSG_DISCONNECT errors, sporadic in the sense that it never occurs at the same place, but still consistent enough to break any build that implies 2-3 artifact deployment. Are those known issues? I can keep things working using scpexe, but I'd really prefer getting the speed of scp... Any suggestions? Thanks, Steve
Re: scp vs scpexe
Wow, the change in sshd_config had no effect (I think Protocol 2,1 is actually default), but turning on nscd seems to have solved my problem... Thanks!

Our developers recently were experiencing problems with cvs within eclipse, where the ext method worked fine(system command ssh) but not with extssh(eclipse builtin) after our sysadmin changed over to LDAP authentication. The problems were similiar to what you describe. Our system admin turned on nscd(name service cacher) and in the /etc/ssh/sshd_config file on the server, uncommented the line that said Protocol 2,1 since the default for ssh is protocol 2 but Eclipse uses protocol 1. Assuming that Eclipse uses some basic Java ssh/scp api and Maven does the same, the problem may be the same. Hope this helps.

Re: scp vs scpexe
Steve, I think the SSH_MSG_DISCONNECT problem can be solved by upgrading the dependency on jsch.
