Couldn't get password entry for current user (0): No such file or directory

• エラー出力箇所

    if (pw == NULL)
        fatal("Couldn't get password entry for current user (%i): %s",
            original_uid, strerror(errno));

• getpwuid 定義

  #define getpwuid xcegetpwuid

• xcegetpwent でファイルの走査

struct passwd *
xcegetpwent(void)
{

  if(fpw == NULL)
    return NULL;

  if(feof(fpw))
    return NULL;

  if(fgets(pwbuf, sizeof(pwbuf), fpw) == NULL)

    strcat(path, "etc\\passwd");
  else
    strcat(path, "\\etc\\passwd");

  fpw = fopen(path, "rt");

• XCEGetEnvironmentVariableFromRegA 定義

int
XCEGetEnvironmentVariableFromRegA(const char *name, char *buf, int len)
{

  if((res = XCERegOpenKeyExA(HKEY_LOCAL_MACHINE, "Environment", 0,
                             KEY_READ, &hKey)) != 0)
    {
      return 0;
    }

#define getuid xcegetuid

int
xcegetuid()
{
  return 0;
}

root:x:0:0:root:/root:/bin/bash

Cannot open \SD Card\UnixRoot/etc/services

ssh 22/tcp

その他の設定

.ssh ディレクトリの作成

root:x:0:0:root:/SD Card/UnixRoot/root:/bin/bash

ログ出力先の変更

[HKEY_LOCAL_MACHINE\Environment]
"CELIBSTDLOGDIR"="\\SD Card\\UnixRoot\\var\\log"

TERM 指定

[HKEY_LOCAL_MACHINE\Environment]
"TERM"="vt100"

起動引数

> ssh
> ssh username@hostname
> ssh username@hostname -i "/SD Card/id_rsa"
> ssh username@hostname -1 -i "/SD Card/identity"

• username@hostname を省略しても問題ない(コンソールで入力を求められる)
• SSH1/SSH2 ともに接続可
• id_rsa を .ssh ディレクトリに置いておけば勝手に読みにいく
