[rofug] SSHd openpty: No such file or directory
Dragos
Folosesc de multa vreme sshd in jail. Instaland o masina noua cu
8.0-CURRENT am constatat ca nu ma mai pot loga.
Eroarea pe care sshd o da in log-uri este:
error: openpty: No such file or directory
error: session_pty_req: session 0 alloc failed
In client dupa autentificare imi da "Server refused to allocate pty
"si ramane blocat(nu deconecteaza).
La trecerea de la freebsd 7 la 8 cred ca s-a renuntat la
device-urile pty in favoarea pts/. Posibil ca rezolvarea sa fie
compilarea openssh cu --with-pty=pts, insa
cum buildworld nu e in stare sa compileze corect sshd si sshd nu apare
ca port, fiind integrat in sistemul de baza, nu stiu cum sa repar
problema asta.
Ciudat este ca sshd-ul merge fara probleme in sistemul mare. Doar in
jail pare sa aiba aceasta problema.

Din ce spune in log-uri nu poate aloca device-ul:
error: openpty: No such file or directory
error: session_pty_req: session 0 alloc failed
login as: dagos
Authenticating with public key "rsa-key-20090701"
Passphrase for key "rsa-key-20090701":
Server refused to allocate pty
In Jail, /dev/ nici cu intregul /dev/ al sistemului montat nu merge
(devfs -m /usr/local/JAIL/SSHd/dev/ rule apply unhide)
Sistemul contine strictul necesar si folosesc genul asta de ssh in jail
de multa vreme si pe multe masini. Jailul contine strictul necesar sshd,
ssh, telnet si bash.
Este ciudat deoarece dev/pts/ exista in jail.
