[Dxspider-support] New build, things not working from within crontab

[Keith Maton]

Hi Kin,

I do have sysop user and spider group, at least, as far as I’m aware.

Just to clarify, you’re saying to log in as sysop and run those four commends?  Is that effectively checking and fixing the permissions?

I want to be sure I understand what I’m doing before I do it.

Thanks,

73 Keith
