Subject: [rlug] ciudatenie de java sub linux
> Am instalat java sdk 1.4.0, si programe simple de gen hello world merg
> bine. Dupa care am facut doua programele, unul transmite un string
> printr-un socket, celalalt il receptioneaza, il afiseaza si trimite
> inapoi o confirmare. Pe windows a mers fara nazuri, dar in linux cand ii
> dau un "java ServerS 127.0.0.1" primesc mesajul urmator:
> [mugur@enkidu mugur]$ java ServerS 127.0.0.1
> Am pornit serverul!
> Inchid sochetul!
> [mugur@enkidu mugur]$ java ServerS
> Am pornit serverul!
> Inchid sochetul!
>
> Ceva e in neregula aici. Am oprit si iptables, just in case, si tot nu
> merge. Ba mai mult, daca le rulez ca root, lucrurile merg ca pe roate.
> Deci unde e problema de permisiuni, si ce trebuie sa fac sa o corectez ?
> Am un redhat 8.0.
