Zašto ne mogu da se konektujem na 127.0.0.1?

[ Astral Projection @ 17.06.2006. 18:27 ] @

Znači ranije samo mogao da testiram ssh i ircd dok sam offline. Znači bilo je potrebno da se konektujem na 127.0.0.1 i normalno sve radi. Međutim sad ne mogu da se konektujem a ne znam zašto. Jednostavno dobijem ovo:

shiva:/home/astral# ssh 127.0.0.1 22
ssh: connect to host 127.0.0.1 port 22: Network is unreachable

Ili kad pokrenem ircd i pokušam da se konektujem dobijem:

[17:46:57] * Looking up 127.0.0.1
[17:46:57] * Connecting to 127.0.0.1 (127.0.0.1) port 6667...
[17:46:57] * Connection failed. Error: Network is unreachable

Mogu li ovo kako riješiti? Inače:

shiva:/home/astral# cat /etc/hosts
127.0.0.1 shiva
127.0.0.1 localhost

shiva:/home/astral# cat /etc/hostname
shiva

(ako je ovo dvoje kome trebalo uopšte) :)

P.S. Dok sam offline i hoću da startujem unreal dobijem

[Sat Jun 17 14:55:12 2006] - TimeSync: WARNING: Was unable to send message to server #2...

Ako se ne varam problem je do ovoga Time Sync-a, ali šta je to ustvari? :)
Još jedna stvar. Kad sam konektovan na net javlja mi:

astral@shiva:~$ ssh 127.0.0.1
ssh: connect to host 127.0.0.1 port 22: No route to host

Što da radim?

[ niceness @ 17.06.2006. 19:40 ] @

Daj output od route -n pre i posle konektovanja na net,
i probaj stavi u /etc/hosts
127.0.0.1 shiva localhost
a ona druga dva unosu izbaci.
Da li si nesto menjao u skorije vreme?

A sta ti ifconfig komanda vraca?

[ niceness @ 17.06.2006. 21:34 ] @

Probaj dodati loopback putanju

route add -net 127.0.0.0 netmask 255.0.0.0 lo

Stvarno vise ne znam sto da radim :|

btw, sad se sjetih.. neki KDE programi mi malo zastekaju pripaljenju a strace vrati ovo: (KWRITE)

bind(11, {sa_family=AF_INET, sin_port=htons(990), sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EACCES (Permission denied)
connect(11, {sa_family=AF_INET, sin_port=htons(111), sin_addr=inet_addr("127.0.0.1")}, 16

i ovdje malo stane i onda se upali poslije mozda minut. Mozda je to vezano sa ovim :)

ping 127.0.0.1 mi daje:

Kod tebe nesto nije u redu.
Kucaj ifconfig lo up, pa vidi sta ce se desiti
i daj ceo dmesg (dmesg > dmesg.log, pa taj fajl zakaci uz poruku)

[ Astral Projection @ 17.06.2006. 22:54 ] @

shiva:/home/astral# ifconfig lo up
shiva:/home/astral#

samo ovo

probao sam komandu #ifconfig eth0 127.0.0.1 i sad mi vrace ovo

astral@shiva:~$ ping 127.0.0.1
connect: Invalid argument

[ niceness @ 17.06.2006. 23:12 ] @

Posle pokretanja ifconfig lo up trebao si da proveris sa ifconfig da li je loopback podignut,
ona druga komanda nije bila potrebna.
Ajde prvo restartuj racunar, pa odmah potom pokreni dmesg i daj output ovde.

Interesuje me moram li svaki put kad bootujem da kucam ifconfig lo 127.0.0.1?
radi ssh, ircd, apache... veliko hvala.. dugujem ti nesto za ovo :)

[ VRider @ 18.06.2006. 00:27 ] @

Pogledaj konfiguracione fajlove, jer je lo interface sigurno greskom iskljucen.

[ Astral Projection @ 18.06.2006. 00:34 ] @

OK, a gdje se sad nalaze conf fajlovi?

[ VRider @ 18.06.2006. 00:40 ] @

Nikad nisam koristio Debian, ali, postoji osnovana sumnja da je u pitanju /etc/network/interfaces.
Trebalo bi da postoji ovakva linija --- iface lo inet loopback;
Nakon toga odradi restart mreze --- /etc/init.d/networking restart

[ niceness @ 18.06.2006. 00:48 ] @

VRider je u pravu, u pitanju je /etc/network/interfaces.
Pokusaj sa ovim podesavanjima:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

[ Astral Projection @ 18.06.2006. 00:58 ] @

# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

iface dsl-provider inet ppp
provider dsl-provider
# please do not modify the following line
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf

ovo mi sad stoji.. dodao sam na kraju ove linije sto mi je niceness rekao
hvala jos jednom
