Hello together,
I have set up a PC using jhalfs with SVN-20200201. This is not the first
time installing LFS for me.
Base is a raid made with BTRFS in MSDOS-Mode. After the base system was
setup (fixed fstab, kernel 5.5.1 compiled with btrfs, grub ) I installed
still in changeroot
- Lynx with zip/unzip/shareutils
- DHCPCD
- Sudo with LinuxPam(rebuild shadow)
- Openssh with Pam-configuration
- wget (after libtasn/p11kit/make-ca)
Lynx, wget are working, sudo is working, ssh from that PC towards other
PC's in my network are working fine.
Connecting from another PC onto the LFS-PC fails. The cennection gets
established and shuts down right away again.
I checked
/proc/sys/net/core/netdev_max_backlog 1000
/proc/sys/net/core/somaxconn 4096
The connection protocol:
[herbert@msi-lap ~]$ ssh -vv [email protected]
OpenSSH_8.1p1, OpenSSL 1.1.1d FIPS 10 Sep 2019

A restart of the LFS-PC does not change anything, as much as the tried
restart of the opensshd-service did not helped. Disabeling LinuxPam in
opensshd_config did also not help.
I have purched opennsh also already using porg, and re-installed it
again. Same result.
Changing protocol to sftp, using FileZilla was also not a success.
I hope to get a hint where to look, I am running out of ideas, what to
google.
Best regards
Herbert
