Dupa ce incearca sa faci ssh pe masina respectiva, uita-te in /var/log/messages dupa ssh si vezi ce zice.

[mufa]

Daca incerci sa faci ssh pe masina respectiva de pe alta masina, ce se intimpla ?
Porneste si sshd-ul in debug mode si vezi ce se intimpla.

[GabyBoy]

nu inteleg ce vreis a zici

[cianura]

posibil sa nu te lase sa te loghezi ca root
ssh username@localhost

posibil sa nu te lase sa te loghezi de pe loopback/IP-ul masiniii; de pe o alta masina incearca:
ssh username@IP-masina-nazdravana

SSH merge la tine, trebuie sa verifici si ca nu ai vreun firewall prin zona.

[GabyBoy]

ok... acum o s avad (IMG:style_emoticons/default/tongue.gif) ms..

[GabyBoy]

salut... Nustiu ce sa fac... am incercat din nou sa deshid ssh`ul 22... merge zice [OK] Dar cand incerc sa intru pe portu ala nu merge (IMG:style_emoticons/default/sad.gif) (( ce se intampla... dc nu se deshide... sau dc nu merge sa intru pe portu ala ??! ce sa fac ??! mercy... poate de data asta gasim raspunsul la aceasta intrtebare care ma framanta de multa vreme (IMG:style_emoticons/default/biggrin.gif) ... se poate ca sa existe firewall sis a nu dea voie sa intru pe portu ala ??? cum il scot.. sa imi dea voie sa intru ?? mercy mult tuturor !!!!!

[GabyBoy]

aha... am aflat ceva... am dat asa: ssh 10.13.0.1

si s-a conectat ...

Last login: Sun Apr 24 03:58:25 2005 from 10.13.0.1
No value for $TERM and no -T specified
No value for $TERM and no -T specified
[root@local root]# ps x

ma-m logat ca root.. dar acum nustiu cum sa deschid port pe ssh sa ma loghez direct.. acum am bind deschis pe telnet (IMG:style_emoticons/default/sad.gif) si nu imi convine sa imi intre toti in el (IMG:style_emoticons/default/biggrin.gif)

10.13.0.1 fiind ipul de pe server


stie cineva ce sa fac ?? sa mearga ssh`ul ?

[Alice]

oooooooooooooooooooooooof gramatica asta bat-o vina...

[retele]

...mercy... mercy  mult tuturor !!!!!

Probabil tu îţi închipui ca eşti "jmeker", dar să ştii că mercy înseamnă milă în engleză....
Ori foloseşti clasicul mulţumesc, ori mersi, sau franţuzescul merci...

[GabyBoy]

dar tu esti smecher ma ?
mai bine taci !

[cianura]

dar tu esti smecher ma ?

[OT]
Atentie la limbaj. Valabil si pt tine si pt retele care sper sa nu se lase antrenat in flame. Oricum, din pctul meu de vedere sa stii ca retele are un punct de vedere intemeiat.[/OT]

Revenind, ai cautat sa vezi daca nu cumva ai firewall intre tine si server? Ai incercat sa te legi de la consola prin ssh?Ti-am spus ca e posibil ca login-ul de root sa fie dezactivat (si pe buna dreptate). Creaza un cont de user normal, te loghezi ca username@ip-host si apoi folosesti su sau sudo ca sa obtii drepturi de root.
