- I have seen a lot of explanations for this problem -- some seem pretty
- farfetched (6 messages in this thread so far).
-
- Anyway, we had the same problem, called DIGITAL Support and got this
- fix. As soon as we applied it, the pause went away (it first showed up
- under Ultrix 4.0, and it is still there under 4.2).
-
- 1. cd /usr/etc
-
- 2. mv dlogind dlogind.merge.mips
-
- 3 cat > dlogind
- #! /bin/sh
- ctermd_writemerge=5
- ctermd_forcedelay=50
- export ctermd_writemerge
- export ctermd_forcedelay
- exec /usr/etc/dlogind.merge.mips
- ^D
-
- 4. chmod 755 dlogind
-
- That is the solution we use and we haven't been bothered by the pause
- since.
-
- Hope it helps.
